5、安装MySQL
 
检查是否安装mysql,使用YUM 自动安装:
 
[root@server ~]# rpm –qa |grep mysql
 
 [root@server ~]# yum -y install mysql mysql-server  #是否要安装,输入Y即可自动安装,直到安装完成
 
 
 
启动MySQL
 
[root@server ~]# service mysqld start
 
                                                          [确定]
 
正在启动 mysqld:                                          [确定]
 
 
 
设为开机启动
 
[root@server ~]# chkconfig mysqld on
 
 
 
[root@server ~]# cp /etc/my.cnf /etc/my.cnfbak
 
[root@server ~]# cp /usr/share/mysql/my-medium.cnf /etc/my.cnf
 
cp:是否覆盖"/etc/my.cnf"? y  #拷贝配置文件(注意:如果/etc目录下面默认有一个my.cnf,直接覆盖即可)
 
 
 
为root账户设置密码
 
[root@server ~]# mysql_secure_installation
 
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
 
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!
 
 
 
In order to log into MySQL to secure it, we'll need the current
 
password for the root user.  If you've just installed MySQL, and
 
you haven't set the root password yet, the password will be blank,
 
so you should just press enter here.
 
 
 
Enter current password for root (enter for none):  #按回车键
 
OK, successfully used password, moving on...
 
 
 
Setting the root password ensures that nobody can log into the MySQL
 
root user without the proper authorisation.
 
 
 
Set root password? [Y/n] y      #输入y
 
New password:              #输入新密码
 
Re-enter new password:        #重输入新密码
 
Password updated successfully!
 
Reloading privilege tables..
 
 ... Success!
 
 
 
By default, a MySQL installation has an anonymous user, allowing anyone
 
to log into MySQL without having to have a user account created for
 
them.  This is intended only for testing, and to make the installation
 
go a bit smoother.  You should remove them before moving into a
 
production environment.
 
 
 
Remove anonymous users? [Y/n] y    #输入y
 
 ... Success!
 
 
 
Normally, root should only be allowed to connect from 'localhost'.  This
 
ensures that someone cannot guess at the root password from the network.
 
 
 
Disallow root login remotely? [Y/n] y    #输入y
 
 ... Success!
 
 
 
By default, MySQL comes with a database named 'test' that anyone can
 
access.  This is also intended only for testing, and should be removed
 
before moving into a production environment.
 
 
 
Remove test database and access to it? [Y/n] y    #输入y
 
 - Dropping test database...
 
 ... Success!
 
 - Removing privileges on test database...
 
 ... Success!
 
 
 
Reloading the privilege tables will ensure that all changes made so far
 
will take effect immediately.
 
 
 
Reload privilege tables now? [Y/n] y    #输入y
 
 ... Success!
 
 
 
Cleaning up...
 
 
 
All done!  If you've completed all of the above steps, your MySQL
 
installation should now be secure.
 
 
 
Thanks for using MySQL!    #最后出现:Thanks for using MySQL!
 
 
 
MySql密码设置完成,重新启动 MySQL:
 
[root@server ~]# service mysqld restart
 
停止 mysqld:                                              [确定]
 
正在启动 mysqld:                                          [确定]
 
[root@server ~]# service mysqld stop
 
停止 mysqld:                                              [确定]
 
[root@server ~]# service mysqld start
 
正在启动 mysqld:                                          [确定]
 
[root@server ~]#linux
