第一步：安装Apache

1.1安装Apache

yum install httpd httpd-devel

1.2启动Apache服务器 

systemctl start  httpd

1.3设置httpd重启服务器 

systemctl enable  httpd

1.4一些步骤（centos7.4忽略因为它的centos7.4）

#查看服务状态
    [root@nmserver-7 ~]# systemctl status httpd


#防火墙设置开启80端口
[root@nmserver-7 ~]# firewall-cmd --permanent --zone=public  --add-service=http
success
[root@nmserver-7 ~]# firewall-cmd --permanent --zone=public  --add-service=https
success
[root@nmserver-7 ~]# firewall-cmd --reload
success


#确认80端口监听中
[root@nmserver-7 ~]# netstat -tulp

1.5测试Apach成功  

两步安装mysql：

2.1：安装mysql

[root@nmserver-7 ~]# yum install mariadb mariadb-server mariadb-libs mariadb-devel

root@nmserver-7 ~]# rpm -qa |grep maria
mariadb-libs-5.5.52-1.el7.i686
mariadb-5.5.52-1.el7.i686
mariadb-server-5.5.52-1.el7.i686
mariadb-devel-5.5.52-1.el7.i686

2.2启动mysql服务器并设置open system start并检查mysql状态

[root@nmserver-7 ~]# systemctl start  mariadb

[root@nmserver-7 ~]# systemctl enable  mariadb

[root@nmserver-7 ~]# systemctl status  mariadb 





[root@nmserver-7 ~]# netstat -tulp

2.3：数据库安全设置 

[root@nmserver-7 ~]# mysql_secure_installation 

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, 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): 
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] y
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB 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
 ... 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] n
 ... skipping.

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
 - 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
 ... 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!

2.4登录数据库测试

[root@nmserver-7 ~]# mysql -uroot -p
Enter password:

~                                                                                        
~                                                                                        
~

:wq

3.5重启Apach服务器

[root@nmserver-7 html]# systemctl restart httpd

3.6测试PHP

           输入地址：ip / info.php

所以灯安装好了！但是没有通过客户端连接数据库！因为没有打开数据库电源，一般有两种状态！这些会谈下一篇文章！
