Mysql57

Description

This contrib purpose is to help configuring mysql57 on 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 5.7.

Most of configuration options are explained for mysql here : MySQL are also available for mysql57 ( except innoDB options). Only difference is to prefix mysqld and mysql.init db entry by "mysql57-".

Note that default behaviour will be socket only, and if you enable networking, it will listen on 3309 locally. You then will need to open port to 3309 to access remotely. Also if you want another port you need to define mysql57-mysqld property port to whatever you want. Also remember that default mysql port is reserved to original mysql server

this RPM will allow you to have 2 versions of mysql running!!!

Installation

A description of the Redhat Software Collections can be found here and can be downloaded manually from here

To use these repos on SME please see this page http://wiki.contribs.org/PHP_Software_Collections

For SME 9.x 64-bit ONLY

for the rebase of Red-Hat sfotware collection : http://mirror.centos.org/centos/6/sclo/x86_64/rh/

/sbin/e-smith/db yum_repositories set centos-sclo-rh repository \
Name 'Centos - RH Software Collections' \
BaseURL 'http://mirror.centos.org/centos/$releasever/sclo/$basearch/rh/' \
EnableGroups no \
Visible yes \
status disabled

For the community based software collection: http://mirror.centos.org/centos/6/sclo/x86_64/sclo/

/sbin/e-smith/db yum_repositories set centos-sclo-sclo repository \
Name 'Centos - RH Software Collections' \
BaseURL 'http://mirror.centos.org/centos/$releasever/sclo/$basearch/sclo/' \
EnableGroups no \
Visible yes \
status disabled

Be carefull some collection are available on both repo, and migh conflict : sclo-python27 and (rh/) python27.

After adding it to the database updating the configuration file is required by issuing:

signal-event yum-modify

yum install --enablerepo=smecontribs,centos-sclo-rh smeserver-mysql57

	Warning:
	You have to do the signal-event post-upgrade; signal-event reboot; or your mysql57 installation will remain in a definitive failed state. They are MANDATORY.

signal-event post-upgrade
signal-event reboot

	Warning:
	Again, If you do not issue the previous two commands and try to start the service on your own you will end with a non functional mysql server, failed in the middle of its initialization with no way to return back except by deinstalling it all and manually remove all (absolutely all) created files by the failed initialization

NB : starting from SME 9.2 and smeserver-yum-2.4.0-15.el6.sme.noarch.rpm installed you will be able to install this scl version of mysql57 simply doing the following, without enabling the rh scl repo :

yum install --enablerepo=smecontribs smeserver-mysql57

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:3309), 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/mysql57.sock
localhost;unix_socket=/var/lib/mysql/mysql57.sock
localhost:3309

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

define( 'DB_HOST', 'localhost:/var/lib/mysql/mysql57.sock' );

command line

For your convenience, aliases have been added : mysql57, mysqlshow57, mysqladmin57, mysqldump57, mysqlimport57 and mysqlbinlog57

mysql57 wordpress

will connect you to database wordpress in mysql57 server, and let you with the mysql prompt to work.

However the full command line to access, per instance to mysql57 server with the mysql client agianst its version would be :

/opt/rh/rh-mysql57/root/usr/bin/mysql  --socket=/var/lib/mysql/mysql57.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 mysql57-mysqld stop
expand-template /root/.my.cnf
expand-template /var/service/mysql57-mysqld/set.password
/opt/rh/mysql57/root/usr/libexec/mysqld --socket=/var/lib/mysql/mysql57.sock --bootstrap --user=mysql --skip-grant-tables < /var/service/mysql57-mysqld/set.password
service mysql57-mysqld start
