How to install Apache, MariaDB and PHP on CentOS 7 minimal

After install and configure network under CentOS 7 minimal I continue with LAMP section. Since the machine has 4GB memory I prefer to use old fashion LAMP. Only switch MySQL with MariaDB 🙂

The steps for LAMP installation for my own reference and my vps need :

Install required Package

Install nano

# yum install nano

Install Apache, PHP and MariaDB

# yum install httpd mariadb-server mariadb php php-mysql php-mysqli php-gd php-pear php-mbstring

Configure Apache

Start httpd

# systemctl start httpd.service

Set httpd to auto start after reboot or boot process

# systemctl enable httpd.service
ln -s ‘/usr/lib/systemd/system/httpd.service’ ‘/etc/systemd/system/multi-user.target.wants/httpd.service’

By default firewall will block access. To exclude http from firewall block :

# firewall-cmd --permanent --add-service http

# systemctl restart firewalld.service

Try visit ip address from browser

httpd_centos7

Configure MariaDB

Start mariadb

# systemctl start mariadb

Set mariadb to autostart

# systemctl enable mariadb.service
ln -s ‘/usr/lib/systemd/system/mariadb.service’ ‘/etc/systemd/system/multi-user.target.wants/mariadb.service’

Set password for mariadb, delete unnecessary database and users.

# mysql_secure_installation
/usr/bin/mysql_secure_installation: line 379: find_mysql_client: command not found

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!

I also need to enable firewall to exclude future database remote backup. Port 3306 is required to open.

# firewall-cmd --permanent --add-port=3306/tcp
success
# systemctl restart firewalld.service

Done.

Next step is measure time needed from start server to get login display and make my report.
