安装mysql后，启动时候没有启动成功，查看了下日志报错如下:---------------------------------------------

1   可以：初始化mysql：mysql_install_db

2   目录权限问题chown -R mysql:mysql  /var/lib/mysql

[root@localhost local]# less /var/log/mysqld.log
1、查看报错信息如下:
[ERROR] Fatal error: Can‘t open and lock privilege tables: Table ‘mysql.host‘ doesn‘t exist

2、经过查阅资料得知。要敲如下命令解决:
mysql_install_db –usrer=mysql datadir=/var/lib/mysql
datadir是我的mysql存放文件目录

3、然后重启mysql还是不行:
MySQL Daemon failed to start.
正在启动 mysqld：                                          [失败]

4、然后试了下单独的命令，启动完成
mysql_install_db

5、启动mysql服务
[root@mysql mysqld]# /etc/init.d/mysqld restart
停止 mysqld：                                              [确定]
正在启动 mysqld：                                         [确定]
