CTRL+D退出。
#vi /etc/profile #添加系统环境变量。
export MYSQL_HOME=/usr/local/mysql/bin
export PATH=$PATH:$MYSQL_HOME
重启让环境变量生效。
启动：
引用
#cd /usr/local/mysql
#mysqld_multi --config-file=/usr/local/mysql/bin/my_multi.cnf start 1,2,3,4


查看端口是否被监听
#netstat -lt |grep 33
tcp     0    0 *:3301      *:*       LISTEN      
tcp     0    0 *:3302      *:*       LISTEN
tcp     0    0 *:3303      *:*       LISTEN      
tcp     0    0 *:3304      *:*       LISTEN
停止某实例的mysql
#mysqld_multi  --config-file=/usr/local/mysql/bin/my_multi.cnf stop 1,2,3,4
访问方法：
#mysql -u root -S /tmp/mysql_5_1.sock -p
添加
#mysqld_multi --config-file=/usr/local/mysql/bin/my_multi.cnf start 1,2,3,4
至/etc/rc.local开机自动启动。
