mysql安装教程

1．使用yum安装mysql数据库的软件包 

[root@xuegod63 ~]# yum -y install mariadb-server mariadb 

注：  

mariadb-server  #MariaDB数据库 

mariadb      # MariaDB服务器Linux下客户端 

注：从centos7系统开始，系统中自带的mysql数据库变成了mariadb-server，mariadb-server和mysql操作上一样。mariadb-server是mysql的一个分支。

2．启动数据库服务

[root@xuegod63 ~]# systemctl start  mariadb #启动MariaDB服务

[root@xuegod63 ~]# systemctl enable  mariadb #设置开启自动启动MariaDB服务

3. 安装完mariadb-server后，运行mysql_secure_installation去除安全隐患

[root@xuegod63 ~]# mysql_secure_installation #进入安全配置导向

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):  #初次运行直接回车，因为root用户没有密码

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 #是否设置root用户密码,输入Y

New password: 123456  #新密码123456

Re-enter new password: 123456

Password updated successfully!

。。。

Remove anonymous users? [Y/n] Y  #是否删除匿名用户,生产环境建议删除，所以直接回车或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 #是否禁止root远程登录,根据自己的需求选择Y/n并回车,建议禁止

 ... Success!

By default, MariaDB 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  #是否删除test数据库,直接回车或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  #是否重新加载权限表，直接回车

 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB

installation should now be secure.

Thanks for using MariaDB!

… Success!

至此数据库安装成功。

4. 登录数据库

[root@xuegod63 ~]# mysql -u root -p123456 

MariaDB [(none)]> show databases;    #没有test数据库 #执行时，所有命令以；号结尾 

+-------------------------+ 

| Database | 

+-------------------------+ 

| information_schema | 

| mysql | 

| ucenter | 

+-------------------------+ 

3 rows in set (0.00 sec) 

MariaDB [(none)]> exit #退出命令可以加分号，也可以不加分号。

总结：

1、使用yum安装mysql数据库的软件包 

2、启动数据库服务

3、运行mysql_secure_installation去除安全隐患

4、登录数据库
