talend 连接mysql数据库没有权限

使用talend连接一个mysql数据库，提示没有权限，最后发现mysql服务器的配置中只监听了127.0.0.1的端口，拒绝非本地的请求。通过将/etc/mysql/my.cnf中的bind_address项注释掉，/etc/init.d/mysql restart重启mysql服务器后，talend可以正常的访问该数据库：

root@ubuntu:~/extract/extract_mysql# vi /etc/mysql/my.cnf ## The MySQL database server configuration file.## You can copy this to one of:# - "/etc/mysql/my.cnf" to set global options,# - "~/.my.cnf" to set user-specific options.# # One can use all long options that the program supports.# Run program with --help to get a list of available options and with# --print-defaults to see which it would actually understand and use.## For explanations see# http://dev.mysql.com/doc/mysql/en/server-system-variables.html# This will be passed to all mysql clients# It has been reported that passwords should be enclosed with ticks/quotes# escpecially if they contain "#" chars...# Remember to edit /etc/mysql/debian.cnf when changing the socket location.[client]port= 3306socket  = /var/run/mysqld/mysqld.sock# Here is entries for some specific programs# The following values assume you have at least 32M ram# This was formally known as [safe_mysqld].

使用grant all 对部署talend的机器ip赋予权限：
