Setup LAMP on centos 7

Here are steps provided to install LAMP on centos 7.

Check version of OS using command

cat /etc/redhat-release

Command to install all packages required for Apache, mysql and php

yum install httpd php php-mysql mariadb-server -y

Let’s enable and start all services using commands

systemctl enable httpd mariadb

Now start httpd and mariadb services.

systemctl start httpd mariadb

Try to access your server IP in browser and you will find apache accessible.

To check php version execute following command

echo "<?php phpinfo(); ?>" > /var/www/html/phpinfo.php

Try to access this page using url

http://IP-of-machine/phpinfo.php

Let’s configure mysql service.

To configure MariaDB, run ‘mysql_secure_installation’

[root@midnight~]# 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: NewPasswordHere
Re-enter new password: NewPasswordHere
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!

 

Now your server is ready to host website supporting php and mysql database.

creating database without cpanel user prefix

Creating mysql user and database without cPanel user prefix.

By default cPanel used to create database and DB user with cPanel username _as prefix. But now cPanel version 68 allows you to disable prefixing so you can create single DBs and DB users.

You can enable disable prefix feature from

WHM > Tweak Setting >  Require a username prefix on names of new databases and database user

Example: If you create database with name wp as cPanel user india. It will create database as india_wp but if you disable this then it will allow you to create database with name wp only.

Automated Backup of mysqlDB on cpanel

Here we will learn how to backup all databases of cPanel server in specified folder say /home/mysqlbackup

First of all we will list all databases in a file using command

  • echo “show databases” | mysql > /home/DB_list.txt

By default first line of the output is DATABASE and rest of lines are name of databases.

Second command will help to get rid of first line.

  • tail -n +2 /home/DB_list.txt > /home/DB_list2.txt

So we have DB_list2.txt with list of all databases.

Here we will use for loop to backup all databases listed in DB_list2.txt

  • for m in `cat /home/DB_list2.txt`;do mysqldump $m > /home/mysqlbackup/$m.sql;done
