mysql [ERROR] Fatal error: Can't open and lock privilege tables: Table 'mysql.host' doesn't exist （转载）

 

在安装MySQL后，启动时候没有启动成功，查看了下日志报错如下:

---------------------------------------------

[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]
