以下笔记为简略记录，详细实战内容待补充。

修改yum源

http://mirrors.aliyun.com/repo/Centos-6.repo

[zeal@data1 ~]$ cd /etc/yum.repos.d/

[zeal@data1 yum.repos.d]$ sudo vi CentOS-Base.repo

[root@data1 yum.repos.d]# yum clean all

[root@data1 yum.repos.d]# yum install mysql-server

[root@data1 /]# which mysql

/usr/bin/mysql

[root@data1 /]# service mysqld status

mysqld 已停

[root@data1 /]# service mysqld start

初始化 MySQL 数据库： Installing MySQL system tables...

OK

Filling help tables...

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 data1.zeal.name 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 /usr/mysql-test ; perl mysql-test-run.pl

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