yum install mysql 装好了，

运行mysql

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)。有文章说是权限问题，后来把权限搞成777也不行。说是没启动MYSQL。那就启动吧

[root@localhost mysql]# service mysql start

mysql: unrecognized service

不行。。。网上也找不到个所以然来。说是用RC.D启动

/etc/rc.d/init.d/mysqld start

-bash: /etc/rc.d/init.d/mysqld: No such file or directory

依然不行。

后来找文章，有人是装的mysql-server.就把前面装的删了。删除用yum remove mysql  。YUM还是很方便的，呵呵。

再yum install mysql-server

装好了。启动

 [root@localhost mysql]# service mysql start

mysql: unrecognized service

再试

 [root@localhost mysql]# service mysqld start

居然成功了！！！(红色是本人自己的试法)

 

 

 

如果依旧。。。。。。。。继续下面的操作

然后 /etc/rc.d/init.d/mysql 启动

/etc/init.d/mysqld start

OK

To start mysqld at boot time you have to copy

support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !

To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'

/usr/bin/mysqladmin -u root -h localhost.localdomain password 'new-password'

Alternatively you can run:

/usr/bin/mysql_secure_installation

which will also give you the option of removing the test

databases and anonymous user created by default.  This is

strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

cd /usr ; /usr/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

cd mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/bin/mysqlbug script!

好了。。竟然。。。呵呵

加到自启动了吧。省的麻烦

chkconfig mysqld on

注意一下，这里是mysqld 不是mysql

运行一下mysql

[root@localhost /]# mysql

Welcome to the MySQL monitor.  Commands end with ; or \g.

Your MySQL connection id is 2

Server version: 5.0.77 Source distribution

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

 

呵呵，好了！问题解决了！

再试试 [root@localhost mysql]# service mysqld restart

Stopping MySQL:                                            [  OK  ]

Starting MySQL:                                            [  OK  ]

都OK了！
