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

/etc/rc.d/init.d/mysqld start -bash: /etc/rc.d/init.d/mysqld: No such file or directory 依然不行。

 有人是装的mysql-server. 删除用yum remove mysql 。

再yum install mysql-server

装好了。启动

[root@localhost mysql]# service mysql start mysql: unrecognized service

然后 /etc/rc.d/init.d/mysql 启动

/etc/init.d/mysqld start Initializing MySQL database: Installing MySQL system tables... 110112 15:24:06 [Warning] option ‘max_join_size‘: unsigned value 18446744073709551615 adjusted to 4294967295 110112 15:24:06 [Warning] option ‘max_join_size‘: unsigned value 18446744073709551615 adjusted to 4294967295 OK Filling help tables... www.111cn.net

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: www.111cn.net 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!

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.

再试试 [root@localhost mysql]# service mysqld restart Stopping MySQL: [ OK ] Starting MySQL: [ OK ]

都OK了！
