Bye多实例设置服务:
停止MySQL服务用 pkill mysqld , 启动服务用 /usr/local/mysql/support-files/mysqld_multi.server start
1.设置开机自启 ：把 /usr/local/mysql/bin/support.files/mysqld_multi.server 文件复制到 /etc/init.d/mysqld.server
[root@localhost ~]# cd /etc/init.d/
[root@localhost init.d]# cp /usr/local/mysql/support-files/mysqld_multi.server ./mysqld.server
[root@localhost init.d]# ls
functions mysqld.server README
[root@localhost init.d]# 2. 在/etc/init.d/mysqld.server 文件中增加环境变量设置 export PATH=/usr/local/mysql/bin: $PATH
[root@localhost init.d]# vim mysqld.server
16 export PATH=/usr/local/mysql/bin/:$PATH //添加环境变量3. chkconfig --add mysqld.server
[root@localhost init.d]# chkconfig --add mysqld.server
[root@localhost init.d]# chkconfig --list注：该输出结果只显示 SysV 服务，并不包含
原生 systemd 服务。SysV 配置数据
可能被原生 systemd 配置覆盖。 要列出 systemd 服务，请执行 'systemctl list-unit-files'。查看在具体 target 启用的服务请执行'systemctl list-dependencies [target]'。mysqld.server 0:关 1:关 2:开 3:开 4:开 5:开 6:关
