問題描述

阿里云ECS 安裝了mysql 5.6，使用 systemctl start mysql成功啟動mysql，可使用 systemctl enable mysql將mysql加入到開機自啟動，可卻報錯：

[root@go ~]# mysql -Vmysql Ver 14.14 Distrib 5.6.29, for Linux (x86_64) using EditLine wrapper[root@go ~]#[root@go ~]# systemctl enable mysqlFailed to execute operation: No such file or directory[root@go ~]# systemctl enable mariadbFailed to execute operation: No such file or directory[root@go ~]#

使用systemctl enable mariadb 也是一樣的，我在Linode中的centos7是直接使用 systemctl enable mariadb 加入自啟動的

但是運行 systemctl enable httpd 是沒有報錯。

問題解答

systemctl list-unit-files 查看下有沒有mysql.service 文件

systemctl enable mysqld

systemctl enable mysqld.service

上面層主說的幾個命令都試了，還是沒有用：ystemctl enable mysqld.servicemysqld.service is not a native service, redirecting to /sbin/chkconfig.Executing /sbin/chkconfig mysqld on[root@iZj6c5y812icw80hzp696gZ ~]# systemctl enable mysqldmysqld.service is not a native service, redirecting to /sbin/chkconfig.Executing /sbin/chkconfig mysqld on[root@iZj6c5y812icw80hzp696gZ ~]# /sbin/chkconfig mysqld onhttp://aliyun.youhuima.cc

===========更新=============

找到了解決方法：編輯文件：vi /etc/rc.d/rc.local增加下面命令，保存/etc/rc.d/init.d/mysqld start

然后添加該文件可執行權限：chmod +x /etc/rc.d/rc.local

經過驗證該方案可行。
