Cenos7下nginx+mysql+php环境的搭建

首先更新系统软件

$ yum update

第一步：安装nginx

1.安装nginx源

$ yum localinstall http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

2.安装nginx

$ yum install nginx

3.启动nginx

$ service nginx start

Redirecting to /bin/systemctl start nginx.service

4.访问http://你的ip/

如果成功安装会出来nginx默认的欢迎界面

第二步：安装mysql

RPM安装MySQL：

1.下载安装包

wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

2.准备

rpm -ivh mysql-community-release-el7-5.noarch.rpm

3.安装mysql

yum install -y mysql-community-server

4.成功安装之后重启mysql服务：

service mysqld restart 或 systemctl restart mysqld.service

初次安装mysql是root账户是没有密码的：

　　mysql -u root -p 　　遇到密码提示，回车即可进入

设置root密码的方法：

quit; 退出mysql

　　mysqladmin -u root password "root" 设置密码

进入mysql：

　　mysql -u root -p

　　Enter Password: root

设置mysql最大连接数：

　　执行sql：set global max_connections = 3000; (重启mysql后失效)

第三步：PHP源码安装：

1. 下载源码包

wget http://cn2.php.net/distributions/php-5.6.3.tar.gz

2.解压

tar zxvf php-5.6.3.tar.gz

cd php-5.6.3

4.安装php依赖包

yum install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl 
libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel 
gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel

libmcrypt 和libmcrypt-devel 依赖包

yum install epel-release //扩展包更新包
yum update //更新yum源
yum install libmcrypt libmcrypt-devel mcrypt mhash 就ok了

5.编译配置，这一步我们会遇到很多configure error，我们一一解决，基本都是相关软件开发包没有安装导致

 ./configure \--prefix=/usr/local/php \--with-config-file-path=/etc \--enable-fpm \--with-fpm-user=nginx  \--with-fpm-group=nginx \--enable-inline-optimization \--disable-debug \--disable-rpath \--enable-shared  \--enable-soap \--with-libxml-dir \--with-xmlrpc \--with-openssl \--with-mcrypt \--with-mhash \--with-pcre-regex \--with-sqlite3 \--with-zlib \--enable-bcmath \--with-iconv \--with-bz2 \--enable-calendar \--with-curl \--with-cdb \--enable-dom \--enable-exif \--enable-fileinfo \--enable-filter \--with-pcre-dir \--enable-ftp \--with-gd \--with-openssl-dir \--with-jpeg-dir \--with-png-dir \--with-zlib-dir  \--with-freetype-dir \--enable-gd-native-ttf \--enable-gd-jis-conv \--with-gettext \--with-gmp \--with-mhash \--enable-json \--enable-mbstring \--enable-mbregex \--enable-mbregex-backtrack \--with-libmbfl \--with-onig \--enable-pdo \--with-mysqli=mysqlnd \--with-pdo-mysql=mysqlnd \--with-zlib-dir \--with-pdo-sqlite \--with-readline \--enable-session \--enable-shmop \--enable-simplexml \--enable-sockets  \--enable-sysvmsg \--enable-sysvsem \--enable-sysvshm \--enable-wddx \--with-libxml-dir \--with-xsl \--enable-zip \--enable-mysqlnd-compression-support \--with-pear \--enable-opcache

6.编译与安装

make && make install

这里要make好久，要耐心一下

7.添加 PHP 命令到环境变量

vim /etc/profile

在末尾加入

PATH=$PATH:/usr/local/php/bin

export PATH

要使改动立即生效执行

./etc/profile

或

source /etc/profile

查看环境变量

echo $PATH

查看php版本

php -v

8.配置php-fpm

cp php.ini-production /etc/php.ini

cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf

cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

chmod +x /etc/init.d/php-fpm

9.启动php-fpm

/etc/init.d/php-fpm start

10.配置nginx虚拟机,绑定域名

vim /etc/nginx/conf.d/default.conf

把下面的内容复制到default.conf里

server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;

    location / {

autoindex on;autoindex_exact_size off;autoindex_localtime on;

        root /usr/share/nginx/html;
        index  index.html index.htm;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root  /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php$ {
        root           /usr/share/nginx/html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

server {
    listen       80;
    server_name localhost;

    #charset koi8-r;
    #access_log /var/log/nginx/log/host.access.log main;

    location / {
        root   /usr/share/nginx/html;
        index index.html index.htm;
    }

    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80

    location ~ \.php$ {
        root           /var/www/;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {

    #}
}
