Disabling listening IPv6 in config file of Apache2 server

By default, Apache will listen on all IPs, both IPv6 and IPv4.
This is controlled by the Listen directive:

root@localhost ~ # egrep -r Listen /etc/apache2
/etc/apache2/ports.conf:Listen 80
root@localhost ~ # 

To turn off IPv6 in Apache, just change the Listen directive to:


This will limit Apache to listening only to IPv4 connections. Repeat this for port 443 if you want to stop Apache from listening for HTTPS on IPv6.

Installing Ruby, Gem, Thin and Redmine on Linux in User Space with CloudLinux

Ruby is best known as the language behind the rails web application framework. However, it is a very flexible general purpose language that can be used for tasks of direct interest to R Developers (parsing files, interacting with databases, processing XML or JSON, math functions, statistics, machine learning, etc).

If you do not have root access on a Linux server, you may still be able to install the ruby language and rubgems. Start by checking the version currently installed (if any):

user@lve [~]# which ruby
user@lve [~]# ruby --version
ruby 1.8.7 (2009-06-12 patchlevel 174) [x86_64-linux]
user@lve [~]#

automysqlbackup: Unknown table engine ‘PERFORMANCE_SCHEMA’

This error seems to be related to the MySQL-Bug #58406 (status: verified).

For the moment, you can ignore that message. The process skips the table and continues as always.
