MYSQL TO MARIA DB SWITCH

What is MariaDB ?
MariaDB is a binary drop in replacement of the same MySQL version (for example MySQL 5.1 -> MariaDB 5.1, MariaDB 5.2 & MariaDB 5.3 are compatible. MySQL 5.5 will be compatible with MariaDB 5.5). What this means is that:
* Data and table definition files (.frm) files are binary compatible.
* All client APIs, protocols and structs are identical.
* All filenames, binaries, paths, ports, sockets, and etc… should be the same.
* All MySQL connectors (PHP, Perl, Python, Java, .NET, MyODBC, Ruby, MySQL C connector etc) work unchanged with MariaDB.
* The mysql-client package also works with MariaDB server.
* The shared client library is binary compatible with MySQL’s client library.


*There are some installation issues with PHP5 that you should be aware of ( REF:https://mariadb.com/kb/en/installation-issues-with-php5 ).


#mysqldump --all-databases --routines --triggers > /home/db_dump/alldb.sql
# service mysql stop
# cp -r /var/lib/mysql/mysql /home/db_dump/
# service mysql start



# /scripts/update_local_rpm_versions --edit target_settings.MySQL50 uninstalled
# /scripts/update_local_rpm_versions --edit target_settings.MySQL51 uninstalled
# /scripts/update_local_rpm_versions --edit target_settings.MySQL55 uninstalled


Disable the targets so cPanel no longer handles MySQL updates ONLY FOR cPanel 11.36+

# /scripts/check_cpanel_rpms --fix --targets=MySQL50,MySQL51,MySQL55


Above command remove rpms


#nano /etc/yum.repos.d/MariaDB.repo

name = MariaDB
baseurl = http://yum.mariadb.org/5.5/centos6-amd64

Create yum repo , Edit the mariadb version and os distribution by checking current statistics



 yum install MariaDB-server MariaDB-client MariaDB-devel
# /etc/init.d/mysql start

Apache tuning documentation

Apache bench marking ======================= Things or checklist to be considered before the test     CPU: avoid power-saving mode. cpufreq-set -g performance.     File descriptors: raise the limit to (at least) the number of concurrent connections you wish to handle, using ulimit -n in your shell, or setrlimit(RLIMIT_NOFILE) in your server. Beware, some systems forbid you to raise the limit, you might need to investigate a bit to find how to unlock it.     Disable the logs of your server (you do not want to lose time logging thousands of requests instead of answering them).     Raise /proc/sys/net/somaxconn to the number of concurrent connections you want to handle. To understand why this is necessary, read the technical report or the excellent paper Measuring the Capacity of a Web Server (Banga and Druschel, Usenix 97). More on the fascinating topic of the accept() queue can be found in accept()able Strategies for Im...
