yum install mysql 裝好了，
運行mysql ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)。有文章說是權限問題，後來把權限搞成777也不行。說是沒啟動MYSQL。那就啟動吧
[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。
有人是裝的mysql-server. 刪除用yum remove mysql 。
再yum install mysql-server
裝好了。啟動
[root@localhost mysql]# service mysql start mysql: unrecognized service
然後 /etc/rc.d/init.d/mysql 啟動

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!

加到自啟動了吧。省的麻煩
chkconfig mysqld on
注意一下，這裡是mysqld 不是mysql
運行一下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.
再試試 [root@localhost mysql]# service mysqld restart Stopping MySQL: [ OK ] Starting MySQL: [ OK ]
都OK了！
