1 描述
使用 OEL7.2 系统 system 管理源码安装的 mysql5.7 多实例.
2 操作环境
2.1OS info
OEL7.2 x64
3 过程设计
编辑 /etc/my.cnf，本文创建 mysqld@3307.service 与 mysqld@3308.service 两个实例，分别对应 3307 与 3308 端口。创建相应实例目录。
复制 systemd 服务文件, 复制 mysql base 目录下 /usr/local/mysql/usr/lib/systemd/system/ 的 mysqld@.service 文件到系统 /usr/lib/systemd/system 目录下，并重命名成与多实例名一致的文件。
systemctl daemon-reload
systemctl start mysqld@3307.service
systemctl start mysqld@.service3308
