Fedora 18 安装完MySQL 无法启动问题

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

# chown mysql.mysql -R *
# service mysqld start这个时候，mysql 就启动成功了。。更多Fedora相关信息见Fedora 专题页面 http://www.linuxidc.com/topicnews.aspx？tid=5Oracle RMAN 清除归档日志Ubuntu 通过Deb 安装 MySQL 5.5相关资讯 Fedora 18 Fedora MySQL 启动MySQL
