PHP 5.4 is available in centos 7 main repository . To install PHP 7.x we need to install remi repository on the centos server. To do this we need to execute the below steps.

Installation Steps of PHP 7.0, 7.1 & 7.2 on CentOS 7 Server

To install remi repo first we need to install EPEL repo and yum-utils .To install these packages we need to execute the below command.

[root@localhost ~]#yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm

Base on your requirement, configure the PHP 7.x repository

To configure PHP 7.0 repository, execute below command,

[root@localhost ~]#yum-config-manager --enable remi-php70

To configure PHP 7.1 repository, execute below command,

[root@localhost ~]#yum-config-manager --enable remi-php71

To configure PHP 7.2 repository, execute below command

[root@localhost ~]#yum-config-manager --enable remi-php72

After doing the above tasks we execute the below command to install the php packages.

[root@localhost ~]#yum install php php-common php-opcache php-mcrypt php-cli php-gd php-curl php-mysql -y

How to install and simple setup LAMP stack on CentOS 7 step by step guide

January 04, 2019 Add Comment Edit

In this article we learn what is LAMP stack and how to install and setup LAMP stack on centos 7.

What is LAMP stack

LAMP stack is used to host web site as well as web application on server.LAMP stand for Linux,Apache(to host the web site),Mysql (to store the data used as a database server),Php (for php application).

Install Apache web server on centos 7

To install apache server execute the below command.

[root@localhost ~]# yum install httpd

After installing the APACHE server we need to turn on(enable the APACHE service at the startup mode) httpd service to turn on the service we execute the below command.

For linux(5/6)

#chkconfig httpd on

For linux 7

#systemctl enable httpd

To start,stop and restart the APACHE service we need to execute the below command.

For linux(5/6)

#service httpd start

#service httpd stop

#service httpd restart

For linux 7

#systemctl start httpd

#systemctl stop httpd

#systemctl restart httpd

How to install and simple setup LAMP stack on CentOS 7 step by step guide

Install Mariadb server on centos 7

To install MariaDB on CentOS 7 we need to execute the below command.

#yum install mariadb-server mariadb

To start and enable the MariaDB service on CentOS 7 we need to execute the below command.

#systemctl start mariadb

#systemctl enable mariadb

CentOS 7 uses firewalld as a software firewall instead of iptables. By default MariaDB server is running on 3306 port. We need to allow this port into firewall rule to access it. To allow the incoming connection to the standard MySQL tcp port we need to execute the below command.

#firewall-cmd - -permanent - -add-service=mysql

#firewall-cmd -- reload

To secure MariaDB we use “mysql_secure_installation” .After executing the “mysql_secure_installation” command we need to set root password,remove test database, remove anonymous user login and disable the remote login.

#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] y

... 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

- 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!

After that restart the service using the below command.

#systemctl restart mariadb

Install PHP on centos 7

To install php on centos server we need to execute the below command.

yum install php php-mysql php-gd

after executing this above command we need to restart the httpd service using the below command.

#systemctl restart httpd

That’s all. We have configured the LAMP stack. If this article is helpful please share it!!!!!
