        Failed to issue method call: Unit mysql.service failed to load: No such file or directory的解决办法

        1、软件环境：

        OpenSUSE 13.1 x64

        MySQL 5.6.20 x64

        2、采用RPM包安装MySQL 5.6.20

# rpm -ivh MySQL-server-5.6.20-1.sles11.x86_64.rpm# rpm -ivh MySQL-client-5.6.20-1.sles11.x86_64.rpm# rpm -ivh MySQL-devel-5.6.20-1.sles11.x86_64.rpm# rpm -ivh MySQL-shared-5.6.20-1.sles11.x86_64.rpm
3、查看MySQL服务 # /etc/init.d/mysql statusMySQL is not running                                                                                                    failedmysql.service   Loaded: not-found (Reason: No such file or directory)   Active: inactive (dead)Aug 22 15:42:26 173-168-58-139 systemd[1]: Stopped LSB: Start the MySQL database server.

        可见，MySQL服务未启动。

4、启动MySQL服务 # /etc/init.d/mysql startredirecting to systemctl start mysqlFailed to issue method call: Unit mysql.service failed to load: No such file or directory.报错，无法启动MySQL服务。
用systemctl方法
# systemctl start mysql.service仍然报如下错误
Failed to issue method call: Unit mysql.service failed to load: No such file or directory. See system logs and 'systemctl status mysql.service' for details.

        5、解决方法
# systemctl enable mysql.service
6、再次启动MySQL # systemctl start mysql# ps -ef | grep mysqlroot     27930     1  0 16:30 ?        00:00:00 /bin/sh /usr/bin/mysqld_safe --datadir=/var/lib/mysql --pid-file=/var/lib/mysql/173-168-58-139.pidmysql    28045 27930  0 16:30 ?        00:00:00 /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib64/mysql/plugin --user=mysql --log-error=/var/lib/mysql/173-168-58-139.err --pid-file=/var/lib/mysql/173-168-58-139.pidroot     28074 25545  0 16:30 pts/1    00:00:00 grep --color=auto mysql可见，MySQL已经正常运行。
