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 status
MysqL is not running                                                                                                    Failed
MysqL.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 start
redirecting to systemctl start MysqL
Failed 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 MysqL
root     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.pid
MysqL    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.pid
root     28074 25545  0 16:30 pts/1    00:00:00 grep --color=auto MysqL

可见，MysqL已经正常运行。
