我有一个魔鬼的时间试图让MySQL启动Fedora的安装。
每当我尝试启动它，我会得到：
[root@server1 log]# service mysqld start Redirecting to /bin/systemctl start mysqld.service Job failed. See system logs and 'systemctl status' for details. 然后当我做一个systemctl查询时，我得到：
[root@server1 log]# systemctl status mysqld.service mysqld.service - MySQL database server Loaded: loaded (/lib/systemd/system/mysqld.service; enabled) Active: failed since Sat, 18 Aug 2012 21:06:48 -0400; 1min 59s ago Process: 747 ExecStartPre=/usr/libexec/mysqld-prepare-db-dir (code=exited, status=254) CGroup: name=systemd:/system/mysqld.service
有趣的是当我检查/var/log/mysqld.log时，那里绝对没有
更新。 我做了mysql_install_db（我甚至应该这样做？），现在这里是我的错误日志看起来像：
