Install Mysql Database on Centos 7
MySQL is a popular choice of database for use in web applications, and is a central component of the widely used LAMP open source web application software stack (and other 'AMP' stacks). LAMP is an acronym for "Linux, Apache, MySQL, Perl/PHP/Python." Free-software-open source projects that require a full-featured database management system often use MySQL.
Not yet in the repos list, so I had to download the lastest MySQL yum repo for mysql from http://dev.mysql.com/downloads/repo/yum/
At the time of this article it was mysql-community-release-el7-5.noarch.rpm
Install MySQL repo
You can download that from our server
wget http://briansnelson.com/stuff/mysql-community-release-el7-5.noarch.rpm
yum localinstall mysql-community-release-el7-5.noarch.rpm
Install MySQL via Yum
yum install mysql-server mysql
Enable MySQL to start on boot
systemctl enable mysqld.service
You should see something like the following:
ln -s '/usr/lib/systemd/system/mysqld.service' '/etc/systemd/system/mysql.service' ln -s '/usr/lib/systemd/system/mysqld.service' '/etc/systemd/system/multi-user.target.wants/mysqld.service'
Disable MySqL from start on boot
systemctl disable mysqld.service
You should see something like the following:
rm '/etc/systemd/system/multi-user.target.wants/mysqld.service' rm '/etc/systemd/system/mysql.service'
Start/Stop/Restart MySQL
Start
systemctl start mysqld.service
Stop
systemctl stop mysqld.service
Restart
systemctl restart mysqld.service
Check if MySQL is running
systemctl is-active mysqld.service
