启动MYSQL是出现以下错误：
[root@www ~]# /usr/local/webserver/mysql/bin/mysqladmin -u root -p 12345678
Enter password:
/usr/local/webserver/mysql/bin/mysqladmin: connect to server at ‘localhost’ failed
error: ‘Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (111)’
Check that mysqld is running and that the socket: ‘/tmp/mysql.sock’ exists!
解决方法：
| 代码如下 | 复制代码 |
|
[root@www ~]# /usr/local/webserver/mysql/bin/mysql -u root -p -S /tmp/mysql.sock Enter password: Welcome to the MySQL monitor. Commands end with ; or g. Your MySQL connection id is 3 Server version: 5.1.38-log Source distribution Type ‘help;’ or ‘h’ for help. Type ‘c’ to clear the current input statement. |

mysql>
mysql的参数说明：
/usr/local/webserver/mysql/bin/mysql –help | less
列举常用参数：
-u, –user=name User for login if not current user.
-p, –password[=name]
Password to use when connecting to server. If password is
not given it’s asked from the tty.
-S, –socket=name Socket file to use for connection.
另一种解决办法
我通过vim /etc/my.cnf，修改了[mysqld]选项下面的socket的值
| 代码如下 | 复制代码 |
| socket=/var/lib/mysql/mysql.sock | |
ok，mysqld可以启动了
接下来，是mysql启动不了，同样，vim /etc/my.cnf,添加了如下脚本：
[mysql]
| 代码如下 | 复制代码 |
| socket=/var/lib/mysql/mysql.sock | |
然后，mysqladmin启动不了，还是一样，在[mysqladmin]下面socket值设置为同样的路径
ok,可以启动了
