Mysql57
Description
This contrib purpose is to help configuring mysql57 on SME9 using software collection.
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!!!

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=smedev,smecontribs,centos-sclo-rh smeserver-mysql57
signal-event post-upgrade signal-event reboot
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
