How To Install MariaDB on Ubuntu 14.04

Install MariaDB on Ubuntu 14.04

MariaDB is a drop-in replacement for MySQL. It is easy to install, offers many speed and performance improvements, and is easy to integrate into most MySQL deployments. MariaDB is widely used and several Linux distributions and large companies have already switched from MySQL to MariaDB.

This article assumes you have at least basic knowledge of linux, know how to use the shell, and most importantly, you host your site on your own VPS.

The installation is quite simple. I will show you through the step by step installation MariaDB on Ubuntu 14.04.

Install MariaDB on Ubuntu 14.04

Step 1. First need to enable MariaDB repository.

sudo apt-get install software-properties-common
sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xcbcb082a1bb943db

Step 2. Installation of MariaDB.

Once the key is imported and the repository added you can install MariaDB with:

apt-get update
apt-get install mariadb-server

At the time of installation mariadb would ask for the password of user root. Enter the password and make sure not to forget.

Step 3. Secure MariaDB after installation to.

By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script. you should read and below each steps carefully which will set root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MariaDB.

# 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!
[root@wpcademy]#

Step 4. Start MariaDB service.

 service mysql start

Step 5. Login into MariaDB.

After completing installation you can connect to MariaDB using following command.

 mysql -u root -p

FTP stands for “file transfer protocol”, and it allows you to transfer files to a remote computer. The most common FTP server software for Ubuntu is the vsftpd package, which stands for “very secure FTP daemon.” It’s the default FTP package for Ubuntu, and most other Linux distributions as well.

This article assumes you have at least basic knowledge of linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple. I will show you through the step by step installation vsftpd on Ubuntu 14.04.

In this tutorial we will show you how to install and configuration of vsftpd on your Ubuntu 14.04 server.

Step 1. Install vsftpd (Very Secure FTP Deamon) package.

#nano /etc/vsftpd.conf

listen=YES
anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022
nopriv_user=vsftpd
virtual_use_local_privs=YES
guest_enable=YES
user_sub_token=$USER
chroot_local_user=YES
hide_ids=YES
guest_username=vsftpd

Step 3. Creating and applying the SSL certificate.

Lets go and create our encryption key or certificate to use to connect to the server. First, create a folder that will be used to store the keys.

 mkdir /etc/ssl/certificates

Then run the commands below to create the encryption key that will last for 365 days.

 sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/certificates/vsftpd.pem -out /etc/ssl/certificates/vsftpd.pem

Once creating the key, go and change add and change these parameters in the default VSFTPD configuration file.

#nano /etc/vsftpd.conf

rsa_cert_file=/etc/ssl/certificates/vsftpd.pem
rsa_private_key_file=/etc/ssl/certificates/vsftpd.pem
ssl_enable=YES
allow_anon_ssl=NO
force_local_data_ssl=YES
force_local_logins_ssl=YES
ssl_tlsv1=YES
ssl_sslv2=YES
ssl_sslv3=YES
require_ssl_reuse=NO
ssl_ciphers=HIGH

Step 4. Restart the vsftpd service.

 service vsftpd restart

Step 5. Configuring user access.

With the vsftpd FTP server you have the option to leave the FTP service authentication for only anonymous access or you can allow users , defined in /etc/passwd or in relevant access list, to login.

Step 6. Configure the user’s home directory.

With certain version of vsftpd you may receive the following error: 500 OOPS: vsftpd: refusing to run with writable root inside chroot(). Not to worry! Create a new directory for the user receiving the error(wpcademy in this case) that is a subdirectory of their home directory (/home/wpcademy). For example:

Fix permissions for wpcademy home directory:

 chmod a-w /home/wpcademy/

Make a new directory for uploading files:

mkdir /home/wpcademy/files
chown wpcademy:wpcademy/home/wpcademy/files/

Congratulation’s! You have successfully installed vsftpd. Thanks for using this tutorial for installing vsftpd in Ubuntu 14.04 system. For additional help or useful information, we recommend you to check the official vsftpd web site.
