在Unix, Linux and Mac OS X 系统中,官方MySQL程序推荐从下面的文件指定的顺序读取启动配置选项: /etc/my.cnf /etc/mysql/my.cnf user-home-dir/my.cnf $MYSQL_HOME/my.cnf 其中$MYSQL_HOME 是指MySQL安装的路径,默认安装在/var/lib/mysql。 在实际环境中

在Unix, Linux and Mac OS X 系统中,官方MySQL程序推荐从下面的文件指定的顺序读取启动配置选项:

/etc/my.cnf
/etc/mysql/my.cnf
user-home-dir/my.cnf
$MYSQL_HOME/my.cnf

其中$MYSQL_HOME 是指MySQL安装的路径,默认安装在/var/lib/mysql。

如何找到MySQL配置文件

在实际环境中,需要准确找到MySQL的配置文件位置,我们可以尝试一下方法。

查看开始MYSQL进程命令的全部命令:

[root@localhost ~]# cat /proc/$(pidof mysqld)/cmdline | tr ‘\0′? ‘\n’
/usr/local/mysql/libexec/mysqld
–basedir=/usr/local/mysql
–datadir=/var/lib/mysql
–user=mysql
–log-error=/var/log/mysqld.log
–pid-file=/var/run/mysqld/mysqld.pid
–socket=/var/lib/mysql/mysql.sock

但这种方法也并不是100%准确的,它可能不会告诉你实际使用的配置文件位置(如上)。
