Second, install Apache
[root@apache ~] # yum-y install httpd
[root@apache ~] # systemctl start httpd
[root@apache ~] # systemctl enable httpd

[root@apache ~] # vim / var/www/html/index.html
Tianyun
[root@apache ~] # vim / var/www/html/2.php
192.168.31.154/index.html
[root@apache ~] # sed-ri'/ ^ SELINUX=/cSELINUX=disabled' / etc/selinux/config
[root@apache ~] # setenforce 0
[root@apache] # firewall-cmd-- permanent-- add-service=http
[root@apache] # firewall-cmd-- permanent-- add-service=https
[root@apache] # firewall-cmd-- reload
Third, install PHP
[root@apache ~] # yum-y install php / / php as a module of Apache
[root@apache ~] # ll / etc/httpd/modules/libphp5.so
-rwxr-xr-x. 1 root root 4588368 Jun 24 2015 / etc/httpd/modules/libphp5.so
[root@apache ~] # ll / etc/httpd/conf.d/php.conf
-rw-r--r--. 1 root root 691 Jun 24 2015 / etc/httpd/conf.d/php.conf
[root@apache ~] # systemctl restart httpd
192.168.31.154/2.php
Fourth, install Mariadb
[root@apache ~] # yum-y install mariadb-server mariadb
[root@apache ~] # systemctl start mariadb.service
[root@apache ~] # systemctl enable mariadb.service
[root@apache ~] # mysql_secure_installation / / improve mariadb security [optional]
Set root password? [Y/n]
New password: 123
Re-enter new password: 123
[root@apache ~] # mysql-uroot-p123 / / login mariadb test
MariaDB [(none)] >\ Q
[root@apache ~] # rm-rf / var/www/html/*
[root@apache ~] # vim / var/www/html/index.php
Test result: php cannot connect to mysql
5. Configure php to connect to Mariadb
[root@apache ~] # yum-y install php-mysql
[root@apache ~] # php-m / / check what extensions are available in php
[PHP Modules]
Mysql
Mysqli
[root@apache ~] # systemctl restart httpd
