Software Collections:MySQL55

Description

This contrib purpose is to help configuring mysql55 on SME8 and SME9 using software collection.

This RPM will allow you to have 2 versions of Mysql running side by side. You will have to select the one to use in the setup of the specific application - please see "usage" below. Please note that applications and contribs like phpmyadmin etc. will as standard use the original Mysql DBM for your OS unless you change the database connection to Mysql 5.5.

Most of configuration options are explained for mysql here : MySQL are also available for mysql55 ( except innoDB options). Only difference is to prefix mysqld and mysql.init db entry by "mysql55-".

Note that default behaviour will be socket only, and if you enable networking, it will listen on 3307 locally. You then will need to open port to 3307 to access remotely. Also if you want another port you need to define mysql55-mysqld property port to whatever you want. Also remember that default mysql port is reserved to original mysql server

signal-event post-upgrade
signal-event reboot

Command line

For your convenience, aliases have been added : mysql55, mysqlshow55, mysqladmin55, mysqldump55, mysqlimport55 and mysqlbinlog55

mysql55 wordpress

will connect you to database wordpress in mysql55 server, and let you with the mysql prompt to work.

However the full command line to access, per instance to mysql55 server with the mysql client against its version would be : If you need to work with this version of MySql on the command line you will have to specify the right socket.

/opt/rh/mysql55/root/usr/bin/mysql  --socket=/var/lib/mysql/mysql55.sock

or use TCP on port 3307:

/opt/rh/mysql55/root/usr/bin/mysql --protocol=TCP --port=3307

Usage

PHP application aware of sockets are few, most of them will try to connect to a port, you will have to find a way to define the one you want to use for your particular app. Some let you put it in a variable, some will just need you to add it after the hostname or ip (localhost:3307), some will just assume 3306 and just ignore anything else.

Possible host strings (localhost can be replaced with 127.0.0.1 if needed):

• localhost:/var/lib/mysql/mysql55.sock
• localhost;unix_socket=/var/lib/mysql/mysql55.sock
• localhost:3307

For Wordpress adjust the DB_HOST value in the wp-config.php file accordingly.

define( 'DB_HOST', 'localhost:/var/lib/mysql/mysql55.sock' );

Resetting the MySQL root password

To reset the password for the MySQL root account. The MySQL root user on SME Server has a random generated password which is generated during installation. You do not need to know this password to login to MySQL with root privileges on SME Server. If you might have changed the MySQL root password you can reset it like this after getting command line access as root user.

service mysql55-mysqld stop
expand-template /root/.my.cnf
expand-template /var/service/mysql55-mysqld/set.password
/opt/rh/mysql55/root/usr/libexec/mysqld --socket=/var/lib/mysql/mysql55.sock --bootstrap --user=mysql --skip-grant-tables < /var/service/mysql55-mysqld/set.password
service mysql55-mysqld start
