Draft notes on installing mariadb 'alongside' mysql

# yum repos aren't useful; use the side-by-side install
# Install mariadb side-by-side with mysql on SME Server v8
# From: https://mariadb.com/kb/en/installing-mariadb-alongside-mysql/
#
# create user 'mariadb' in server-manager
#
cd ~
mkdir -p addons
cd addons
RELEASE=5.5.34
wget https://downloads.mariadb.org/interstitial/mariadb-$RELEASE/kvm-bintar-hardy-x86/mariadb-$RELEASE-linux-i686.tar.gz/from/http://mirror.jmu.edu/pub/mariadb
cd /opt
tar zxvf ~/addons/mariadb-$RELEASE-linux-i686.tar.gz
ln -s mariadb-$RELEASE-linux-i686 mariadb
mkdir mariadb-data
cp mariadb/support-files/my-medium.cnf mariadb-data/my.cnf
#
# edit my.cnf as described on the mariadb-alongside-mysql howto (link above)
chown -R mariadb:mariadb mariadb-data mariadb mariadb-$RELEASE-linux-i686
#
cp mariadb/support-files/mysql.server /etc/init.d/mariadb
chmod +x /etc/init.d/mariadb
#
# edit /etc/init.d/mariadb as described in the howto
#
cd /opt/mariadb
scripts/mysql_install_db --defaults-file=/opt/mariadb-data/my.cnf
cd /etc/init.d
chkconfig --add mariadb 
chkconfig --levels 3 mariadb on
# SME Server uses runlevel 7...
mv /etc/rc3.d/S64mariadb /etc/rc7.d
#
# customizations not mentioned in the howto:
mkdir /var/run/mariadb
chown mariadb:maridb /var/run/mariadb
#
# customize the execution line in /etc/init.d/mariadb
#
# version from howto:
#  $bindir/mysqld_safe --defaults-file=/opt/mariadb-data/my.cnf --datadir="$datadir" --pid-file="$mysqld_pid_file_path" $other_args >/dev/null 2>&1 &
#
# version I'm using:
# $bindir/mysqld_safe --defaults-file=/opt/mariadb-data/my.cnf --datadir="/opt/mariadb-data" --pid-file="/var/run/mariadb/mariadb.pid" $other_args >/dev/null 2>&1 &
#
# Finally, testing access requires asking for a password, then entering an empty password (SME feeds the 'root'@'localhost' password to mysql by default:
# mysql -e "SELECT VERSION();" --port=3307 --protocol=TCP -p
#
# set root password in mariadb same as root password in mysql
mysql --port=3307 --protocol=TCP -p < /var/service/mysqld/set.password
#
# Now the example version check from the howto works:    
mysql -e "SELECT VERSION();" --socket=/opt/mariadb-data/mariadb.sock

Notes on check_earlytalker

Why did you remove the Request_for_deletion template on the check_earlytalker page? AFAIK it is obsolete and should be deleted according to http://forums.contribs.org/index.php/topic,46234.msg226418.html#msg226418 - — Cactus (talk | contribs)  07:05, 16 February 2012 (MST)

Here's my understanding of the Request_for_deletion addition to this page:

1) Piran posted a link to this page in a thread with the text "Install the check_earlytalker plugin": http://forums.contribs.org/index.php/topic,46229.msg226377.html#msg226377

2) Charlie noticed Piran's post, and assumed the wiki page described how to install check_earlytalker, so he made his post that the page is obsolete: http://forums.contribs.org/index.php/topic,46234.msg226418.html#msg226418

3) The page was updated with the 'Request_for_deletion' template

4) I added the reasoning to the 'talk' page outlining why the page is NOT obsolete (see below)

5) Over a year later, I removed the 'Request_for_deletion' template, assuming everyone had read and agreed with the reasoning I outlined on the 'talk' page.

Copied from http://wiki.contribs.org/Talk:Qpsmtpd_check_earlytalker - Unless there is more information elsewhere, I don't feel that this page is obsolete.

Despite the language used by piran in his mention of this page at http://forums.contribs.org/index.php/topic,46229.msg226377.html#msg226377, this page is not about adding check_earlytalker - which is included by default as mentioned by Charlie in the forum post referenced above.

This page is about:

   Documenting the functionality of check_earlytalker (what it does and why it does it)
   Documenting how to change the timeout value applied by check_earlytalker
   Documenting how to monitor check_earlytalker to see if it is being used to deny email
