hy000,(HY000): Cant connect to local ...

安装mysql数据库后，在设置数据库密码的时候报错，错误信息如下:
[root@anchnet client]# mysqladmin -u root password "123456^"
mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/tmp/mysql.sock' exists!
[root@anchnet client]# mysql -uroot -p
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
解决方法：
说明：首先检查是否启动了mysql服务。>>./mysqld_safe --user=mysql&
由于mysql 默认的mysql.sock 是在/var/lib/mysql/mysql.sock，但linux系统总是去/tmp/mysql.sock查找，所以会报错
[root@localhost ~]# find / -name mysql.sock
/var/lib/mysql/mysql.sock
1.直接指定mysql通道
[root@localhost ~]# mysql --socket=/var/lib/mysql/mysql.sock
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 2 to server version: 5.0.22
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql>
2. 创建符号连接：
为mysql.sock增加软连接（相当于windows中的快捷方式）。
ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock
举例:
[root@localhost ~]# mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
[root@localhost ~]# ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock
[root@localhost ~]# mysql
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 3 to server version: 5.0.22
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
