5.配置配置文件/etc/my.cnf
[root@localhost ~]# vim /etc/my.cnf
[root@localhost ~]# cat /etc/my.cnf
[mysqld_multi]
mysqld = /usr/local/mysql/bin/mysqld_safe
mysqladmin = /usr/local/mysql/bin/mysqladmin
[mysqld3306]
datadir = /opt/data/3306
port = 3306
socket = /tmp/mysql3306.sock
pid-file = /opt/data/3306/mysql_3306.pid
log-error=/var/log/3306.log
[mysqld3307]
datadir = /opt/data/3307
port = 3307
socket = /tmp/mysql3307.sock
pid-file = /opt/data/3307/mysql_3307.pid
log-error=/var/log/3307.log
[mysqld3308]
datadir = /opt/data/3308
port = 3308
socket = /tmp/mysql3308.sock
pid-file = /opt/data/3308/mysql_3308.pid
log-error=/var/log/3308.log
6.启动各示例
[root@localhost ~]# mysqld_multi start 3306
-bash: /usr/local/mysql/bin/mysqld_multi: /usr/bin/perl: bad interpreter: No such file or directory //需要下载perl包
[root@localhost ~]# dnf -y install perl
[root@localhost mysql]# yum install ncurses-compat-libs
[root@localhost mysql]# file /usr/local/mysql/bin/mysqld_multi

[root@localhost ~]# mysqld_multi start 3306
[root@localhost ~]# mysqld_multi start 3307
