下午没事,闲的蛋疼,刚搞了一个FTP的服务器,也是个摆设,平时不咋用。所以就想装个MYSQL学习学习。

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
依旧。。。。。。。。

然后 /etc/rc.d/init.d/mysql 启动

/etc/init.d/mysqld start
Initializing MySQL database:  Installing MySQL system tables...

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!
