第一步，用centos安装好mysql.
用yum方法实现。
yum list | grep mysql
mysql安装
然后我们可以通过输入
yum install -y mysql-server mysql mysql-devel
命令将mysql mysql-server mysql-devel都安装好(注意:安装mysql时我们并不是安装了mysql客户端就相当于安装好了mysql数据库了，我们还需要安装mysql-server服务端才行)

我们发现，通过yum方式安装mysql数据库省去了很多没必要的麻烦，当出现下面的结果时，就代表mysql数据库安装成功了
通过以下命令来判断我的mysql是否已经安装成功
rpm -qi mysql-server
启动mysql服务可以用以下命令
service mysqld start
会显示以下信息
[root /]# service mysqld start
Initializing MySQL database: 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 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 /usr/mysql-test ; perl mysql-test-run.pl
Please report any problems with the /usr/bin/mysqlbug script!
[ OK ]
Starting mysqld: [ OK ]
重新启动mysqld
service mysqld restart
之后就是这些信息：
[root /]# service mysqld restart
Stopping mysqld: [ OK ]
Starting mysqld: [ OK ]
我们在使用mysql数据库时，都得首先启动mysqld服务，我们可以 通过 chkconfig --list | grep mysqld命令来查看mysql服务是不是开机自动启动，如：
[root /]# chkconfig --list | grep mysqld
mysqld 0:off 1:off 2:off 3:off 4:off 5:off 6:off
开机自启动
chkconfig mysqld on
检查以下
chkconfig --list | grep mysql
mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off
第二步
