Deploying Lamp in Centos 7

Deploying Lamp in CentOS 7 (linux,apache,mariadb,php)

Description : Centos 7 replaces MySQL with mariadb, but the PHP connection mariadb still uses the Php-mysql module.

"From Wikipedia"
MARIADB database management System is a branch of MySQL, mainly by the open source community in the maintenance, the use of GPL license. One of the reasons for developing this branch is that after Oracle acquired MySQL, there is a potential risk of shutting MySQL out of the source, so the community uses a branching approach to avoid this risk.
MARIADB is designed to be fully compatible with MySQL, including APIs and command lines, making it easy to be a replacement for MySQL. In the storage engine, the 10.0.9 version uses xtradb (named aria) instead of MySQL's InnoDB.

1. Preparation before installation
Shutting down firewalls and Seliux

• temporarily close Seliux setenforce=0

• Temporary shutdown iptables/firewalld systemctl stop Firewalld.service

Temporarily closed, effective immediately, but fails after rebooting the system.

• Permanently close seliux sed-i s/^selinux=enforcing$/selinux=disabled/g/etc/selinux/config

• Permanently close iptables systemctl disable Firewalled.service

Permanently closed, does not take effect immediately, but takes effect after the system restarts.

2. Configure the Yum source

3. Deploying Apache

1. yum Install httpd  //install Apache

2. systemctl start Httpd.service  //Start Apache now

3. systemctl enable Httpd.service  //Add Apache to boot from boot

• Firewall-cmd--zone=public--add-port=80/tcp--permanent

• Firewall-cmd--reload

4. Deploying MARIADB

1. yum Install mariadb-server /install mariadb

2. systemctl Start Mariadb.service

3. systemctl enable Mariadb.service  //Add mariadb to boot from startup

• Firewall-cmd--zone=public--add-port=3306/tcp--permanent

• Firewall-cmd--reload

5. Initialize the MARIADB Administrator password (optional action)

• mysqladmin-u root password ' 123456 ' //Set Administrator password to 123456, default is empty.

5. Deploying PHP

1. Yum install php php-mysql //install PHP and connect mariadb module

2. echo "extension=msql.so" >>/ect/php.ini //Open PHP connection mariadb extension function

6. Verification

1. Create a test page
   

cat/var/www/html/test.php
<?php
$conn = mysql_connect ("localhost", "root", "");
if ($conn)
echo "OK";
Else
echo "Fail";
Mysql_close ();
Phpinfo ();
?>
