二、遇到的问题

（1）lost connection to mysql server at reading initial communication packet system error:0

http://www.jb51.net/article/51480.htm

启动mysql 报错：

（2）ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’ (2)

1、先查看 /etc/rc.d/init.d/mysqld status 看看MySql是否已经启动.

2、确定你的mysql.sock是不是在那个位置，
mysql -u 你的mysql用户名 -p -S /var/lib/mysql/mysql.sock

3、试试：service mysqld start (我遇到的是这种情况)

4、如果是权限问题，则先改变权限 #chown -R mysql:mysql /var/lib/mysql

[root@localhost ~]# /etc/init.d/mysqld start
启动 MySQL： [ 确定 ]
[root@localhost ~]# mysql -uroot -p

（3）host 'xxx.xx.xxx.xxx' is not allowed to connect to this mysql server

mysql> CREATE USER 'monty'@'localhost' IDENTIFIED BY 'some_pass';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'monty'@'localhost'
->     WITH GRANT OPTION;
mysql> CREATE USER 'monty'@'%' IDENTIFIED BY 'some_pass';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'monty'@'%'
->     WITH GRANT OPTION;

(3)1405-Access denied for user (using password: YES)

ip没有访问权限
