1、軟件環(huán)境：

OpenSUSE 13.1 x64

MySQL 5.6.20 x64

2、採(cǎi)用RPM包安裝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服務(wù)

      # /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.
    

可見(jiàn)。MySQL服務(wù)未啟動(dòng)。

4、啟動(dòng)MySQL服務(wù)

      # /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.
    

報(bào)錯(cuò)，無(wú)法啟動(dòng)MySQL服務(wù)。

用systemctl方法

      # systemctl start mysql.service
    

仍然報(bào)例如以下錯(cuò)誤
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、解決方法

      # systemctl enable mysql.service
    

6、再次啟動(dòng)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

      
    

可見(jiàn)，MySQL已被正確執(zhí)行。
