我非常费劲地尝试让 mysql 在 Fedora 安装上启动。
每当我尝试启动它时我都会得到：
[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，当我执行 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，那里什么都没有
更新。我执行了 mysql_install_db（我是否应该执行此操作？），现在我的错误日志如下所示：
