MySQL is a relational database management system (RDBMS) that runs as a server providing multi-user access to a number of databases.

The service version (shown in native reported format ) is:

# mysql --version
mysql  Ver 14.14 Distrib 5.1.37, for debian-linux-gnu (x86_64) using  EditLine wrapper

MySQL is configured to start at the VM boot time.

Before you can access the database from other computers in your network, you have to change its bind address. Note that this can be a security problem, because your database can be accessed by others computers than your own. Skip this step if the applications which require mysql are running on the same machine.

type:

vim /etc/mysql/my.cnf

and change the line:

bind-address           = localhost

to your own internal ip address e.g. 192.168.1.20

bind-address           = 192.168.1.20

To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h ubuntu.domain.com password 'new-password'

Alternatively you can run:

/usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers. See the manual for more instructions.

You can start the MySQL daemon with:

cd /usr ; /usr/bin/mysqld_safe

or using rc.d script:

/etc/init.d/mysql start

Please report any problems with the /usr/bin/mysqlbug script!

The latest information about MySQL is available on the web at

Troubleshooting Apache

If you get this error:

then use a text editor such as vim to create a new file

# vim /etc/apache2/conf.d/fqdn

then add

ServerName localhost

to the file and save. This can all be done in a single command with the following:

echo "ServerName localhost" | sudo tee /etc/apache2/conf.d/fqdn

Virtual Hosts

Apache2 has the concept of sites, which are separate configuration files that Apache2 will read. These are available in /etc/apache2/sites-available. By default, there is one site available called default this is what you will see when you browse to http://localhost or http://127.0.0.1. You can have many different site configurations available, and activate only those that you need.

As an example, we want the default site to be /home/user/public_html/. To do this, we must create a new site and then enable it in Apache2.
To create a new site:

# sudo cp /etc/apache2/sites-available/default /etc/apache2/sites-available/mysite

# vim /etc/apache2/sites-available/mysite

Now, we must deactivate the old site, and activate our new one. Ubuntu provides two small utilities that take care of this: a2ensite (apache2enable site) and a2dissite (apache2disable site).

# sudo a2dissite default && sudo a2ensite mysite

Finally, we restart Apache2:

sudo /etc/init.d/apache2 restart

If you have not created /home/user/public_html/, you will receive an warning message

To test the new site, create a file in /home/user/public_html/:

# echo 'Hello! It is working!' > /home/user/public_html/index.html

Finally, browse to http://localhost/

For more server settings, please check configuration files from /etc/apache2/conf.d/ and /etc/apache2/sites-enabled/ directories.

The system runs under Ubuntu 9.10 (Karmic) Server Edition with the latest set of packages installed on amd64 platform. The kernel is the latest XEN DomU version 2.6.31-14-server designed for Ubuntu distributive.

Image Information & Recommendation:

Storage: The ‘/’ file-system usage is about 835Mb, only 200 packages are installed.
This ‘basic-minimal’ installation provide you an ability to design the system to be much suitable for your needs.
The recommended total disk size is 10Gb. Note: the disk size depend from applications and services you plan to run on the system

Memory: The system use ~100Mb of memory to run mandatory services like init, disk management, logging and networking. We recommend use at least 256Mb of RAM according to the vendors requirements.

CPU and processes: ~70 processes run by default on the system for a minimal CPU load. The recommended CPU is >= 400 MHz

Apache and CloudLinux LVE settings and configuration

The server is configured with:

• mod_hostinglimits - LVE limits for apache
mod_hostinglimits works with existing cgi/php modules, to put them into LVE context. It can switch user/group of apache process (making PHP run under user context) via LVE.

Please take a look into it configuration file /etc/httpd/conf.d/modhostinglimits.conf and find more about module configuration options at http://www.cloudlinux.com/docs/mod_hostinglimits_lve.php

• mod_sucgid - high performance CGI daemon
mod_sucgid is a cross between suExec and mod_cgid. It runs CGI scripts more efficiently via daemon process, but it runs them under correct user id/group id, in similar way to suExec

Please take a look into it configuration file /etc/httpd/conf.d/modsucgid.conf and find more about module configuration options at http://www.cloudlinux.com/docs/mod_sucgid.php

• mod_fcgid - FastCGI for LVE
mod_fcgid is CloudLinux packages modified version of mod_fcgid, that supports LVE

Please take a look into it configuration file /etc/httpd/conf.d/mod_fcgid.conf and find more about module configuration options at http://www.cloudlinux.com/docs/fastcgilve.php
You will get the following warning in case the module is installed but not enabled (by default):

# /etc/init.d/httpd restart
Stopping httpd: [ OK ]
Starting httpd: [Thu Feb 18 08:38:51 2010] [notice] sucgid: LVE is disabled
[Thu Feb 18 08:38:51 2010] [notice] mod_fcgid: LVE is disabled
[ OK ]

To avoid it, just turn on the module. Set EnableLVE On in the config file.

Regular Apache settings and configuration

The server is configured:

• with default settings, please consult the on-line docs for your own settings and change /etc/httpd/conf/httpd.conf if required
• to serve https connections. Please reffer to /etc/httpd/conf.d/ssl.conf configuration file which provides SSL support.
• with Mod_perl - a Perl interpreter into the Apache web server. Configuration file is /etc/httpd/conf.d/perl.conf
• with php5_module - a PHP interpreter version 5 module. Configuration file is /etc/httpd/conf.d/php.conf
• with Mod_python module - the Python language interpreter. Configuration file is /etc/httpd/conf.d/python.conf

For more server settings, plaese check *.conf configuration files from /etc/httpd/conf.d directory.

CloudLinux is an operating system (OS) that is commercially supported and compatible with the most popular RPM-based distribution on the market..

CloudLinux delivers better efficiency and stability to drive a more profitable operation for shared hosting providers and datacenters.
CloudLinux increases server density by improving stability and reliability using isolation technology to create Lightweight Virtual Environments (LVE) Proprietary to CloudLinux, LVEs deliver better resource management by limiting the amount of resources any site can use, so that no single account can slow or take down a whole server

Shared hosters benefits:

• Increase the number of accounts per server, reducing hardware, electricity, data center space and management costs
• Isolation technology prevents any single site from hogging resources or taking down a server
• Improved security reduces outages and means less support time spent managing down servers

Datacenter’s benefits:

• Well tested, commercially supported and maintained OS
• Better security reduces churn and the costs associated with security support issues
• CloudLinux was fine tuned to work well with most popular control panels
• Fully tested for reliability

The service version (shown in native reported format ) is:

# cat /etc/redhat-release
CloudLinux Server release 5.4

# uname -r
2.6.18-264.2.1.el5.7.cloudlinuxxen

# rpm -qa|grep lve
lve-utils-0.3-0.1.20100214git.el5.cloudlinux
lve-0.6rc5-1.20100212git.el5.cloudlinux

Enabling/Desabling LVE

Edit the /etc/sysconfig/lve and setting LVE_ENABLE
Setting it to yes will enable LVE, setting it to no will disable LVE
You need to reboot the server, after you set this option.

Adjusting LVE default values

Values set in /etc/container/ve.cfg are used by default when processes are run within LVE You can edit that file, and run /etc/init.d/lvectl restart To adjust the values

More at Working with LVE

We propose ready to use CloudLinux with Apache installation. Please take a look into the ‘CloudLinux Server 5.4 x64 Apache‘ image.
