Fedora 18 和之前版本的有一些区别 ，故而不能像以前的一样 。 使用 # yum install mysql-server mysql 安装成功后，启动mysql 服务，使用 # systemctl start mysqld.service 可是 会有如下问题Job for mysqld.service failed. See 'systemctl status mysqld.service' and 'journalctl -xn' for details. 使用 # journalctl -xn ，提示 -- Logs begin at 四 2013-04-11 16:13:02 CST, end at 四 2013-04-11 22:07:06 CST. -- 4月 11 22:05:47 localhost.localdomain dbus-daemon[654]: dbus[654]: [system] Rejected send message, 2 matched rules; type="method_return", sender=":1.0 4月 11 22:05:47 localhost.localdomain dbus[654]: [system] Rejected send message, 2 matched rules; type="method_return", sender=":1.0" (uid=0 pid=648 c 4月 11 22:06:13 localhost.localdomain dbus-daemon[654]: ** Message: No devices in use, exit 4月 11 22:07:03 localhost.localdomain systemd[1]: Starting MySQL database server... -- Subject: Unit mysqld.service has begun with start-up -- Defined-By: systemd -- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel -- Documentation: http://www.freedesktop.org/wiki/Software/systemd/catalog/7d4958e842da4a758f6c1cdc7b36dcc5 -- -- Unit mysqld.service has begun starting up. 4月 11 22:07:03 localhost.localdomain mysqld_safe[7422]: 130411 22:07:03 mysqld_safe Logging to '/var/log/mysqld.log'. 4月 11 22:07:04 localhost.localdomain mysqld_safe[7422]: 130411 22:07:04 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql 4月 11 22:07:06 localhost.localdomain mysqld_safe[7422]: 130411 22:07:06 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended 4月 11 22:07:06 localhost.localdomain systemd[1]: mysqld.service: control process exited, code=exited status=1 4月 11 22:07:06 localhost.localdomain systemd[1]: Failed to start MySQL database server. -- Subject: Unit mysqld.service has failed -- Defined-By: systemd -- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel -- Documentation: http://www.freedesktop.org/wiki/Software/systemd/catalog/be02cf6855d2428ba40df7e9d022f03d -- -- Unit mysqld.service has failed. -- -- The result is failed. 4月 11 22:07:06 localhost.localdomain systemd[1]: Unit mysqld.service entered failed state 查看 /var/log/mysqld.log 内容如下 [root@localhost log]# more mysqld.log 130413 13:45:12 mysqld_safe Starting mysqld daemon with databases from /var/lib/ mysql 130413 13:45:12 [Note] Plugin 'FEDERATED' is disabled. /usr/libexec/mysqld: Can't find file: './mysql/plugin.frm' (errno: 13) 130413 13:45:12 [ERROR] Can't open the mysql.plugin table.
