CentOS7下搭建postfix邮箱服务器并实现extmail的web访问

转载http://blog.51cto.com/zero01/2064693

闲来无事想着尝试使用postfix搭建一个邮箱服务器，我是边搭建边写这个笔记，搭建过程中遇到坑也会一并记录，使用的系统版本如下：

[root@localhost ~]# cat /etc/redhat-releaseCentOS Linux release 7.2.1511 (Core)

本示例基于LNMP环境。

1. 准备工作

关闭selinux

[root@localhost ~]# setenforce 0[root@localhost ~]# getenforce Permissive[root@localhost ~]#

关闭firewalld防火墙，并清空iptables规则：

[root@localhost ~]# systemctl stop firewalld[root@localhost ~]# iptables -F[root@localhost ~]# iptables -X[root@localhost ~]# iptables -nvLChain INPUT (policy ACCEPT 38 packets, 7291 bytes) pkts bytes target prot opt in out source destination Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 12 packets, 1208 bytes) pkts bytes target prot opt in out source destination [root@localhost ~]#

由于CentOS7默认安装的是MariaDB，所以要添加MySQL的yum源，有些编译需要的devel包只有epel扩展源有，所以我们需要把epel源也一并添加。因为是通过wget命令从下载地址中下载，但是最小化安装的CentOS7不自带wget命令，还需要先安装这个命令：

yum install -y wgetwget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpmrpm -ivh mysql-community-release-el7-5.noarch.rpmwget http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpmrpm -ivh epel-release-latest-7.noarch.rpm

2. 安装postfix

首先需要安装编译环境及其他所需要的包，免得一会编译过程中老报缺少包的错误，因为需要安装的包有点多，所以这个过程有点慢：

yum install nginx vim gcc gcc-c++ openssl openssl-devel db4-devel ntpdate mysql mysql-devel mysql-server bzip2 php-mysql cyrus-sasl-md5 perl-GD perl-DBD-MySQL perl-GD perl-CPAN perl-CGI perl-CGI-Session cyrus-sasl-lib cyrus-sasl-plain cyrus-sasl cyrus-sasl-devel libtool-ltdl-devel telnet mail libicu-devel  -y

安装完以上所需的包后，开始编译安装postfix：

1.首先卸载系统自带的postfix，并删除postfix用户，重新指定uid、gid创建新用户postfix，postdrop，嫌一条条命令去执行有点麻烦就写成脚本文件去执行：

yum remove postfix -yuserdel postfixgroupdel postdropgroupadd -g 2525 postfixuseradd -g postfix -u 2525 -s /sbin/nologin -M postfixgroupadd -g 2526 postdropuseradd -g postdrop -u 2526 -s /sbin/nologin -M postdrop

2.下载源码包并解压编译（如果下载地址失效就到官网去找下载连接）：

cd /usr/local/src/wget http://cdn.postfix.johnriley.me/mirrors/postfix-release/official/postfix-3.0.11.tar.gztar -zxvf postfix-3.0.11.tar.gzcd postfix-3.0.11make makefiles 'CCARGS=-DHAS_MYSQL -I/usr/include/mysql -DUSE_SASL_AUTH -DUSE_CYRUS_SASL -I/usr/include/sasl -DUSE_TLS ' 'AUXLIBS=-L/usr/lib64/mysql -lmysqlclient -lz -lrt -lm -L/usr/lib64/sasl2 -lsasl2 -lssl -lcrypto' make && make install echo $?

在make install环节的时候会有个交互式的界面，可以自定义一些目录，我这里只更改了第二项临时文件目录，其他的都选择了默认目录：

Please specify the prefix for installed file names. Specify this ONLYif you are building ready-to-install packages for distribution to OTHERmachines. See PACKAGE_README for instructions.install_root: [/] Please specify a directory for scratch files while installing Postfix. You must have write permission in this directory. tempdir: [/usr/local/src/postfix-3.0.11] /tmp/extmail // 就只更改这一项为tmp目录，其他的全部默认 Please specify the final destination directory for installed Postfix configuration files. config_directory: [/etc/postfix] Please specify the final destination directory for installed Postfix administrative commands. This directory should be in the command search path of adminstrative users. command_directory: [/usr/sbin] Please specify the final destination directory for installed Postfix daemon programs. This directory should not be in the command search path of any users. daemon_directory: [/usr/libexec/postfix] Please specify the final destination directory for Postfix-writable data files such as caches or random numbers. This directory should not be shared with non-Postfix software. data_directory: [/var/lib/postfix] Please specify the final destination directory for the Postfix HTML files. Specify "no" if you do not want to install these files. html_directory: [no] Please specify the owner of the Postfix queue. Specify an account with numerical user ID and group ID values that are not used by any other accounts on the system. mail_owner: [postfix] Please specify the final destination pathname for the installed Postfix mailq command. This is the Sendmail-compatible mail queue listing command. mailq_path: [/usr/bin/mailq] Please specify the final destination directory for the Postfix on-line manual pages. You can no longer specify "no" here. manpage_directory: [/usr/local/man] Please specify the final destination pathname for the installed Postfix newaliases command. This is the Sendmail-compatible command to build alias databases for the Postfix local delivery agent. newaliases_path: [/usr/bin/newaliases] Please specify the final destination directory for Postfix queues. queue_directory: [/var/spool/postfix] Please specify the final destination directory for the Postfix README files. Specify "no" if you do not want to install these files. readme_directory: [no] Please specify the final destination pathname for the installed Postfix sendmail command. This is the Sendmail-compatible mail posting interface. sendmail_path: [/usr/sbin/sendmail] Please specify the group for mail submission and for queue management commands. Specify a group name with a numerical group ID that is not shared with other accounts, not even with the Postfix mail_owner account. You can no longer specify "no" here. setgid_group: [postdrop] Please specify the final destination directory for Postfix shared-library files. shlib_directory: [no]

3.更改目录的属主和属组：

chown -R postfix:postdrop /var/spool/postfixchown -R postfix:postdrop /var/lib/postfix/chown root /var/spool/postfixchown -R root /var/spool/postfix/pid

4.修改postfix的配置文件：

[root@localhost ~]# vim /etc/postfix/main.cfmyhostname = mail.everyoo.com//设置主机名mydomain = everyoo.com//指定域名myorigin = $mydomain//指明发件人所在的域名inet_interfaces = //all指定postfix系统监听的网络接口mydestination = $myhostname, localhost.$mydomain, localhost,$mydomain //指定postfix接收邮件时收件人的域名 [使用虚拟域需要禁用] mynetworks_style = host //指定信任网段类型 mynetworks = 192.168.77.1/24, 127.0.0.0/8 //指定信任的客户端 relay_domains = $mydestination //指定允许中转邮件的域名 alias_maps = hash:/etc/aliases //设置邮件的别名

5.然后需要在/etc/init.d/目录下提供一个脚本来管理postfix的启动与停止：

[root@localhost /var/www/extsuite/extman]# vim /etc/init.d/postfix

把下面的内容放在/etc/init.d/postfix里面：

#!/bin/bash## postfix  Postfix Mail Transfer Agent## chkconfig: 2345 80 30 # description: Postfix is a Mail Transport Agent, which is the program \ # that moves mail from one machine to another. # processname: master # pidfile: /var/spool/postfix/pid/master.pid # config: /etc/postfix/main.cf # config: /etc/postfix/master.cf # Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network # Check that networking is up. [ $NETWORKING = "no" ] && exit 3 [ -x /usr/sbin/postfix ] || exit 4 [ -d /etc/postfix ] || exit 5 [ -d /var/spool/postfix ] || exit 6 RETVAL=0 prog="postfix" start() { # Start daemons. echo -n $"Starting postfix: " /usr/bin/newaliases >/dev/null 2>&1 /usr/sbin/postfix start 2>/dev/null 1>&2 && success || failure $"$prog start" RETVAL=$? [ $RETVAL -eq 0 ] && touch /var/lock/subsys/postfix echo retu $RETVAL } stop() { # Stop daemons. echo -n $"Shutting down postfix: " /usr/sbin/postfix stop 2>/dev/null 1>&2 && success || failure $"$prog stop" RETVAL=$? [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/postfix echo retu $RETVAL } reload() { echo -n $"Reloading postfix: " /usr/sbin/postfix reload 2>/dev/null 1>&2 && success || failure $"$prog reload" RETVAL=$? echo retu $RETVAL } abort() { /usr/sbin/postfix abort 2>/dev/null 1>&2 && success || failure $"$prog abort" retu $? } flush() { /usr/sbin/postfix flush 2>/dev/null 1>&2 && success || failure $"$prog flush" retu $? } check() { /usr/sbin/postfix check 2>/dev/null 1>&2 && success || failure $"$prog check" retu $? } restart() { stop start } # See how we were called. case "$1" in start) start ;; stop) stop ;; restart) stop start ;; reload) reload ;; abort) abort ;; flush) flush ;; check) check ;; status) status master ;; condrestart) [ -f /var/lock/subsys/postfix ] && restart || : ;; *) echo $"Usage: $0 {start|stop|restart|reload|abort|flush|check|status|condrestart}" exit 1 esac exit $?

为脚本添加执行权限，并将服务添加到开机启动项中：

[root@localhost /var/www/extsuite/extman]# chmod +x /etc/init.d/postfix[root@localhost /var/www/extsuite/extman]# chkconfig --add postfix[root@localhost /var/www/extsuite/extman]# chkconfig postfix on[root@localhost /var/www/extsuite/extman]# chown postfix.postfix -R /var/lib/postfix/[root@localhost /var/www/extsuite/extman]# chown postfix.postfix /var/spool/ -R

3. 安装dovecot

yum安装：

[root@localhost ~]# yum install -y dovecot dovecot-mysql

配置dovecot：

[root@localhost ~]# cd /etc/dovecot/[root@localhost dovecot]# vim dovecot.conf //直接在配置文件最后添加即可protocols = imap pop3!include conf.d/*.conflisten = *base_dir = /var/run/dovecot/[root@localhost dovecot]# cd conf.d/[root@localhost conf.d]# vim 10-auth.confdisable_plaintext_auth = no[root@localhost conf.d]# vim 10-mail.conf mail_location = maildir:~/Maildir mail_location = maildir:/var/mailbox/%d/%n/Maildir mail_privileged_group = mail [root@localhost conf.d]# vim 10-ssl.conf ssl = no [root@localhost conf.d]# vim 10-logging.conf log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot.info log_timestamp = "%Y-%m-%d %H:%M:%S " [root@localhost conf.d]# cp auth-sql.conf.ext auth-sql.conf [root@localhost conf.d]# vim auth-sql.conf passdb { driver = sql # Path for SQL configuration file, see example-config/dovecot-sql.conf.ext args = /etc/dovecot/dovecot-sql.conf.ext } userdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext }

编辑dovecot通过mysql认证的配置文件：

[root@localhost conf.d]# vim /etc/dovecot-mysql.confdriver = mysqlconnect = host=localhost dbname=extmail user=extmail password=extmaildefault_pass_scheme = CRYPTpassword_query = SELECT useame AS user,password AS password FROM mailbox WHERE useame = '%u'user_query = SELECT maildir, uidnumber AS uid, gidnumber AS gid FROM mailbox WHERE useame = '%u'

4. 安装courier-authlib

下载解压并编译：

[root@localhost ~]# cd /usr/local/src/[root@localhost /usr/local/src]#  wget https://sourceforge.net/projects/courier/files/authlib/0.66.2/courier-authlib-0.66.2.tar.bz2[root@localhost /usr/local/src]# tar -jxvf courier-authlib-0.66.2.tar.bz2 [root@localhost /usr/local/src]# cd courier-authlib-0.66.2 [root@localhost /usr/local/src/courier-authlib-0.66.2]# ./configure --prefix=/usr/local/courier-authlib --sysconfdir=/etc --without-authpam --without-authshadow --without-authvchkpw --without-authpgsql --with-authmysql --with-mysql-libs=/usr/lib64/mysql --with-mysql-includes=/usr/include/mysql --with-redhat --with-authmysqlrc=/etc/authmysqlrc --with-authdaemonrc=/etc/authdaemonrc --with-mailuser=postfix [root@localhost /usr/local/src/courier-authlib-0.66.2]# make && makeinstall

编译过程中发生了一个错误：

configure: error: The Courier Unicode Library 1.2 appears not to be installed. You may need to install a separate development subpackage, in addition to the main package

这是因为Courier Unicode Library没有安装，我们下载courier-unicode-1.2并编译安装：

[root@localhost ~]# wget https://sourceforge.net/projects/courier/files/courier-unicode/1.2/courier-unicode-1.2.tar.bz2[root@localhost ~]# tar jxvf courier-unicode-1.2.tar.bz2 [root@localhost ~]# cd courier-unicode-1.2[root@localhost courier-unicode-1.2]# ./configure[root@localhost courier-unicode-1.2]# make && make install

完成Courier Unicode Library的安装后，倒回去再次编译courier-authlib就没问题了

配置courier-authlib：

[root@localhost  courier-authlib-0.66.2]# chmod 755 /usr/local/courier-authlib/var/spool/authdaemon[root@localhost  courier-authlib-0.66.2]# cp /etc/authdaemonrc.dist  /etc/authdaemonrc[root@localhost  courier-authlib-0.66.2]# cp /etc/authmysqlrc.dist  /etc/authmysqlrc[root@localhost  courier-authlib-0.66.2]# vim /etc/authdaemonrc  //配置文件里的验证方法比较多，我们这里只使用authmysqlauthmodulelist="authmysql" authmodulelistorig="authmysql" [root@localhost courier-authlib-0.66.2]# vim /etc/authmysqlrc //直接添加到配置文件尾部，然后去上面将响应系统默认的注视掉，或者删除即可 MYSQL_SERVER localhost MYSQL_USERNAME extmail MYSQL_PASSWORD extmail MYSQL_SOCKET /var/lib/mysql/mysql.sock MYSQL_PORT 3306 MYSQL_DATABASE extmail MYSQL_USER_TABLE mailbox MYSQL_CRYPT_PWFIELD password DEFAULT_DOMAIN test.com MYSQL_UID_FIELD '2525' MYSQL_GID_FIELD '2525' MYSQL_LOGIN_FIELD useame MYSQL_HOME_FIELD concat('/var/mailbox/',homedir) MYSQL_NAME_FIELD name MYSQL_MAILDIR_FIELD concat('/var/mailbox/',maildir)

courier-authlib添加服务启动脚本及其他：

[root@localhost  courier-authlib-0.66.2]# cp courier-authlib.sysvinit /etc/init.d/courier-authlib[root@localhost  courier-authlib-0.66.2]# chmod +x /etc/init.d/courier-authlib[root@localhost  courier-authlib-0.66.2]# chkconfig --add courier-authlib[root@localhost  courier-authlib-0.66.2]# chkconfig courier-authlib on[root@localhost  courier-authlib-0.66.2]# echo "/usr/local/courier-authlib/lib/courier-authlib" >> /etc/ld.so.conf.d/courier-authlib.conf [root@localhost courier-authlib-0.66.1]# ldconfig [root@localhost courier-authlib-0.66.1]# service courier-authlib start Starting Courier authentication services: authdaemond

smtp以及虚拟用户相关的设置：

[root@localhost ~]# vim /usr/lib64/sasl2/smtpd.conf//文件不存在，要自己创建pwcheck_method: authdaemondlog_level: 3mech_list: PLAIN LOGINauthdaemond_path:/usr/local/courier-authlib/var/spool/authdaemon/socket [root@localhost ~]# vim /etc/postfix/main.cf ##postfix支持SMTP## smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain = '' smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination broken_sasl_auth_clients=yes smtpd_client_restrictions = permit_sasl_authenticated smtpd_sasl_security_options = noanonymous ##postfix支持虚拟用户## virtual_mailbox_base = /var/mailbox virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf //这里的配置文件需在后面extman 里复制过来 virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf virtual_alias_domains = virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf virtual_uid_maps = static:2525 virtual_gid_maps = static:2525 virtual_transport = virtual

安装extmail

下载extmail和extman：

[root@localhost ~]# cd /usr/local/src/[root@localhost /usr/local/src]# wget http://7xivyw.com1.z0.glb.clouddn.com/extmail-1.2.tar.gz[root@localhost /usr/local/src]# wget http://7xivyw.com1.z0.glb.clouddn.com/extman-1.1.tar.gz

创建站点目录并解压、重命名extmail包：

[root@localhost /usr/local/src]# mkdir -p /var/www/extsuite[root@localhost /usr/local/src]# tar -zxvf extmail-1.2.tar.gz -C /var/www/extsuite/[root@localhost /usr/local/src]# mv /var/www/extsuite/extmail-1.2/ /var/www/extsuite/extmail

更改extmail的配置文件：

[root@localhost ~]# cd /var/www/extsuite/extmail[root@localhost extmail]# cp webmail.cf.default webmail.cf[root@localhost extmail]# vim webmail.cfSYS_SESS_DIR = /tmp/extmailSYS_UPLOAD_TMPDIR = /tmp/extmail/uploadSYS_USER_LANG = zh_CNSYS_MIN_PASS_LEN = 8SYS_MAILDIR_BASE = /var/mailboxSYS_MYSQL_USER = extmailSYS_MYSQL_PASS = extmailSYS_MYSQL_DB = extmailSYS_MYSQL_HOST = localhostSYS_MYSQL_SOCKET = /var/lib/mysql/mysql.sockSYS_MYSQL_TABLE = mailboxSYS_MYSQL_ATTR_USERNAME = useameSYS_MYSQL_ATTR_DOMAIN = domainSYS_MYSQL_ATTR_PASSWD = passwordSYS_AUTHLIB_SOCKET = /usr/local/courier-authlib/var/spool/authdaemon/socket

建立临时文件目录与session目录，并更改权限：

[root@localhost extmail]# mkdir -p /tmp/extmail/upload[root@localhost extmail]# chown -R postfix.postfix /tmp/extmail/

安装extman

回到extman的下载目录下，解压extman包：

[root@localhost ~]# cd /usr/local/src/[root@localhost /usr/local/src]# tar -zxvf extman-1.1.tar.gz -C /var/www/extsuite/[root@localhost /usr/local/src]# cd /var/www/extsuite/ [root@localhost /var/www/extsuite]# mv extman-1.1/ extman

拷贝extman的配置文件：

[root@localhost /var/www/extsuite]# cd extman/[root@localhost /var/www/extsuite/extman]# cp webman.cf.default webman.cf

更改cgi目录的属主属组：

[root@localhost /var/www/extsuite/extman]# chown -R postfix.postfix /var/www/extsuite/extman/cgi/[root@localhost /var/www/extsuite/extman]# chown -R postfix.postfix /var/www/extsuite/extmail/cgi/

导入数据库：
由于数据库不能识别TYPE=MyISAM，所以这里直接导入会出错，需要先编辑extmail.sql数据库文件，将文件中的TYPE=MyISAM更改为ENGINE=MyISAM，共有五处修改：

[root@localhost /var/www/extsuite/extman]# vim docs/extmail.sql:% s/TYPE/ENGINE/g

我这里导入数据的时候发生了一个错误，提示找不到mysql.sock文件：

[root@localhost /var/www/extsuite/extman]# mysql -uroot < docs/extmail.sqlERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)[root@localhost /var/www/extsuite/extman]# ls /var/lib/mysql/mysql.sockls: 无法访问/var/lib/mysql/mysql.sock: 没有那个文件或目录

解决：然后我去查看了一下/etc/my.cnf文件，发现没问题，socket参数指向的也是 /var/lib/mysql/mysql.sock 这个路径，于是我就重启了mysql服务，然后再尝试就没有报找不到mysql.sock文件的错误了，但是报了另一个错误：

[root@localhost /var/www/extsuite/extman]# mysql -uroot < docs/extmail.sqlERROR 1364 (HY000) at line 31: Field 'ssl_cipher' doesn't have a default value[root@localhost /var/www/extsuite/extman]#

这错误的意思是：字段 'ssl密码' 没有默认值

于是又得去查看一下/etc/my.cnf文件，然后把sql_mode参数给注释掉：

接着重启mysql服务后，继续导入数据，这次就没问题了：

[root@localhost /var/www/extsuite/extman]# !serviceservice mysqld restartRedirecting to /bin/systemctl restart  mysqld.service[root@localhost /var/www/extsuite/extman]# mysql -uroot < docs/extmail.sql[root@localhost /var/www/extsuite/extman]# mysql -uroot < docs/init.sql

导入数据成功后再次修改/etc/my.cnf文件，把刚刚注释的那行给去掉注释，不去掉的话，mysql服务可能会出现不能启动的问题：

数据导入成功后，登录mysql，创建一个mysql数据库用户extmail并授予权限：

[root@localhost /var/www/extsuite/extman]# mysql -urootmysql> GRANT ALL ON extmail.* to extmail@'%' identified by 'extmail';  //我这里是直接授予全部权限在任意的IP地址上了，实际情况根据需求而定Query OK, 0 rows affected (0.00 sec)mysql> FLUSH PRIVILEGES;Query OK, 0 rows affected (0.00 sec)mysql>

复制之前提到的配置文件：

[root@localhost ~]# cd /var/www/extsuite/extman/docs/[root@localhost /var/www/extsuite/extman/docs]# cp mysql_virtual_* /etc/postfix/

为extman创建临时目录：

[root@localhost /var/www/extsuite/extman/docs]# mkdir /tmp/extman[root@localhost /var/www/extsuite/extman/docs]# chown -R postfix.postfix /tmp/extman/

启动postfix、dovecot、saslauthd服务，并查看进程是否正常：

[root@localhost /var/www/extsuite/extman]# service postfix startStarting postfix (via systemctl):  [  确定  ][root@localhost /var/www/extsuite/extman]# ps aux |grep postfixroot  63586  0.0  0.1  95392  2160 ?Ss01:290:00 /usr/libexec/postfix/master -wpostfix63587  0.0  0.2  95448  3808 ?S01:290:00 pickup -l -t unix -upostfix63588  0.0  0.2  95496  3816 ?S01:290:00 qmgr -l -t unix -uroot  63592  0.0  0.0 112680976 pts/0S+01:330:00 grep --color=auto postfix[root@localhost /var/www/extsuite/extman]# ss -tnluo | grep :25 tcp LISTEN 0 100 *:25 *:* [root@localhost /var/www/extsuite/extman]# service dovecot start Redirecting to /bin/systemctl start dovecot.service [root@localhost /var/www/extsuite/extman]# ps aux |grep dovecot root 63834 0.3 0.0 15652 1484 ?

7. 测试

测试虚拟用户：

[root@localhost courier-authlib-0.66.2]# /usr/local/courier-authlib/sbin/authtest -s login postmaster@extmail.org extmailAuthentication succeeded.//显示这个表示成功，测试时使用的是postmaster@extmail.org，因为我们导入的数据库init.sql里面自带了这个。Authenticated: postmaster@extmail.org  (uid 2525, gid 2525)Home Directory: /var/mailbox/extmail.org/postmaster  //这里需要注意/var/mailbox这个目录现在我们还没有创建，后面web访问的时候如果没有会报错,所以提前创建。Maildir: /var/mailbox/extmail.org/postmaster/Maildir/Quota: (none)Encrypted Password: $1$phz1mRrj$3ok6BjeaoJYWDBsEPZb5C0Cleartext Password: extmailOptions: (none)[root@localhost courier-authlib-0.66.2]# mkdir /var/mailbox [root@localhost courier-authlib-0.66.2]# chown -R postfix.postfix /var/mailbox/

8. 启动nginx实现web访问

nginx本身并不能解析cgi，extmail自带了解析cgi的程序，但是有些地方需要修改下：

[root@localhost ~]# vim /var/www/extsuite/extmail/dispatch-initSU_UID=postfixSU_GID=postfix

启动dispatch-init：

[root@localhost ~]# /var/www/extsuite/extmail/dispatch-init startStarting extmail FCGI server...[root@localhost ~]# /var/www/extsuite/extman/daemon/cmdserver -v -d loaded ok

添加nginx虚拟主机：

vim /etc/nginx/conf.d/extmail.conf

文件内容如下：

server {listen8080;server_name  mail.everyoo.com;index index.html index.htm index.php index.cgi;root  /var/www/extsuite/extmail/html/;location /extmail/cgi/ { fastcgi_pass  127.0.0.1:8888; fastcgi_index index.cgi; fastcgi_param  SCRIPT_FILENAME/var/www/extsuite/extmail/cgi/$fastcgi_script_name; includefcgi.conf;}location  /extmail/  { alias  /var/www/extsuite/extmail/html/;}location /extman/cgi/ { fastcgi_pass  127.0.0.1:8888; fastcgi_index index.cgi; fastcgi_param  SCRIPT_FILENAME/var/www/extsuite/extman/cgi/$fastcgi_script_name; includefcgi.conf;}location /extman/ { alias  /var/www/extsuite/extman/html/;}  access_log  /var/log/extmail_access.log; }

创建fcgi.conf文件：

vim /etc/nginx/fcgi.conf

文件内容如下：

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;fastcgi_param  SERVER_SOFTWAREnginx;fastcgi_param  QUERY_STRING$query_string;fastcgi_param  REQUEST_METHOD $request_method;fastcgi_param  CONTENT_TYPE$content_type;fastcgi_param  CONTENT_LENGTH $content_length;fastcgi_param  SCRIPT_NAME$fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name;

安装Unix::Syslog：

[root@localhost ~]# cd /usr/local/src/[root@localhost /usr/local/src]# wget http://www.cpan.org/authors/id/M/MH/MHARNISCH/Unix-Syslog-1.1.tar.gz[root@localhost /usr/local/src]# tar zxvf Unix-Syslog-1.1.tar.gz [root@localhost /usr/local/src]# cd Unix-Syslog-1.1 [root@localhost /usr/local/src/Unix-Syslog-1.1]# perl Makefile.PL [root@localhost /usr/local/src/Unix-Syslog-1.1]# make && make install

启动nginx，并检查进程和监听端口是否正常：

[root@localhost ~]# service nginx startRedirecting to /bin/systemctl start  nginx.service[root@localhost ~]# ps aux |grep nginxroot  72338  0.0  0.1 122892  2296 ?Ss03:220:00 nginx: master process /usr/sbin/nginxnginx 72339  0.0  0.1 123336  3192 ?S03:220:00 nginx: worker processnginx 72340  0.0  0.1 123336  3192 ?S03:220:00 nginx: worker processnginx 72341  0.0  0.1 123336  3192 ?S03:220:00 nginx: worker processnginx 72342  0.0  0.1 123336  3192 ?S03:220:00 nginx: worker processroot  72344  0.0  0.0 112680976 pts/0S+03:220:00 grep --color=auto nginx[root@localhost ~]# netstat -lntpActive Inteet connections (only servers)Proto Recv-Q Send-Q Local AddressForeign Address StatePID/Program nametcp0  0 0.0.0.0:110 0.0.0.0:*LISTEN  63834/dovecottcp0  0 0.0.0.0:143 0.0.0.0:*LISTEN  63834/dovecottcp0  0 0.0.0.0:80  0.0.0.0:*LISTEN  72338/nginx: master tcp0  0 0.0.0.0:80800.0.0.0:*LISTEN  72338/nginx: master tcp0  0 0.0.0.0:22  0.0.0.0:*LISTEN  1482/sshdtcp0  0 127.0.0.1:8888  0.0.0.0:*LISTEN  64100/dispatch.fcgi tcp0  0 0.0.0.0:25  0.0.0.0:*LISTEN  64328/mastertcp60  0 :::3306 :::*LISTEN  62442/mysqldtcp60  0 :::80:::*LISTEN  72338/nginx: master tcp60  0 :::22:::*LISTEN  1482/sshd[root@localhost ~]#

然后到windows上访问你服务器IP的8080端口：
