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!!!

For SME9 Software collection is only available for x64 architectures.
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:
yum install --enablerepo=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 signal-event post-upgrade ; signal-event reboot
By default mysql57 uses a socket for connections.
PHP applications that are aware of sockets are few, and most typically try to connect to a port. You will have to craft 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):
PHP applications that are aware of sockets are few, and most of them will try to connect to a port. To enable mysql57 to use a port you will need to do the following:
config setprop mysql57-mysqld port 3309 LocalNetworkingOnly no signal-event post-upgrade;signal-event reboot
mysq57 should now be listening on port 3309. you can check this using netstat:
netstat -atn |grep 3309
Beware that some applications just assume the running port number, so to connect to mysql55 on 3307 instead of stock mysql on 3306 you will need to carefully investigate and modify your application accordingly e.g.
For Wordpress adjust the DB_HOST value in the wp-config.php file accordingly.
define( 'DB_HOST', 'localhost:/var/lib/mysql/mysql57.sock' );
For your convenience, aliases have been added : mysql57, mysqlshow57, mysqladmin57, mysqldump57, mysqlimport57 and mysqlbinlog57
Assuming you have a wordpress database setup, the following will connect to database wordpress in mysql57 server, and present the mysql prompt so you can work with the database.
However the full command line to access, per instance to mysql55 server with the mysql client against its version would be :
The complete path to the specific version of mysql57 server with the mysql client would be:
# /opt/rh/rh-mysql57/root/usr/bin/mysql --socket=/var/lib/mysql/mysql57.sock
or use TCP on port 3309:
PHP applications that are aware of sockets are few, and most of them will try to connect to a port. To enable mysql57 to use a port you will need to do the following
# config setprop mysql57-mysqld port 3309 LocalNetworkingOnly no # config show mysql57-mysqld # mysql57-mysqld=service LocalNetworkingOnly=no port=3309 status=enabled # signal-event post-upgrade; signal-event reboot
# /opt/rh/mysql57/root/usr/bin/mysql --protocol=TCP --port=3309
Note that using the regular 5.1 client may work, but can lead to unexpected results. Please avoid this type of command invocation:
# 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
