MariaDB is an open source database server which is created & developed by Michael ‘Monty’ Widenius (creator of MySQL).We can also say MariaDB is drop-in replacement to MySQL Server and is compatible with MySQL database.
In this post we will discuss how to install & connect MariaDB in CentOS 7
By default MariaDB packages are not listed in CentOS repositories , so to install this first we have to enable MariDB repositories.
Setting up MariaDB Repositories
Create a file /etc/yum.repos.d/MariaDB.repo
# MariaDB 10.0 CentOS repository list - created 2014-10-23 13:06 UTC # http://mariadb.org/mariadb/repositories/ [mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.0/centos7-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1
Install MariaDB
Open the terminal and type below yum command.
# yum install MariaDB-server MariaDB-client
while Installing we can get below conflicting error :
Transaction check error:
file /etc/my.cnf from install of MariaDB-common-10.0.14-1.el7.centos.x86_64 conflicts with file from package mariadb-libs-1:5.5.35-3.el7.x86_64
file /usr/share/mysql/charsets/Index.xml from install of MariaDB-common-10.0.14-1.el7.centos.x86_64 conflicts with file from package mariadb-libs-1:5.5.35-3.el7.x86_64
So to resolve this problem remove postfix & mariadb-libs
# yum remove postfix mariadb-libs-5.5.35-3.el7.x86_64
Now Again re-run above yum command to install MariaDB Server
Starting MariaDB Service
[root@localhost ~]# systemctl start mysql.service
Now Set MariaDB root password
[root@localhost ~]# 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!
