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.rpm3、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.serviceFailed 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# 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
