RMagick requires ImageMagick and ImageMagick-devel libraries.
Your distribution may include at least some of these libraries by default and probably provides pre-built packages for the others. If not, these are available as source code tarballs from http://www.imagemagick.org/pub/delegates/.
Or you can install these using the yum command:
$yum install ImageMagick
$yum install ImageMagick-devel
RMagick also needs Windows TureType font, download the rpm from here:
http://www.zacharywhitley.com/linux/rpms/fedora/core/6/i386/msttcorefonts-2.0-1.noarch.rpm
Install this:
$ rpm -ivh msttcorefonts-2.0-1.noarch.rpm
Make a symbolic link the font dir to the place rmagick expects them:
ln -s /usr/share/fonts/msttcorefonts /usr/share/fonts/default/TrueType
Some applications based on RMagick also requires freeimage header files.
Download freeimage from here
http://freeimage.sourceforge.net/download.html
Unzip the file and cd to the freeimage dir and run following commands
# make
# make install
Now install RMagic using the gem
$ gem install RMagick --include-dependencies
memcached is a general-purpose distributed memory caching system.
It is often used to speed up dynamic database-driven websites by caching data and objects in memory to reduce the amount the database needs to be read.
memcached is dependent on libevent library, so firstly download the source files for Libevent
from http://www.monkey.org/~provos/libevent/
Install libevent:
$ tar -xvf libevent-1.3c.tar.gz
$ cd libevent-1.3c
$ ./configure
$ make
$ make install
In Fedora the library (libevent-1.3c.so.1.0.3) will be installed at
/usr/local/lib
Create a link or copy this file to standard libarary location (/lib) of Fedora
$ cd /lib
$ ln -s /usr/local/lib/libevent-1.3c.so.1.0.3 libevent-1.3c.so.1
Download the latest memcached from http://www.danga.com/memcached/download.bml
$ tar -xzf memcached-1.2.2.tar.gz
$ cd memcached-1.2.2
$ ./configure
$ make
$ make install
Running:
$ memcached -h
(Will display various options)
To run as a deoman
$ memcached -d -u apache
Will start as daemon with default options Port(p): 11211 and Max memory (m) to use: 64MB
Download latest & stable nagios from here. Select the tarball
Download
Also download the plugins
Here these steps have been performed on Fedora 2 and Fedora5 using the nagios-2.9 and nagios-plugin-1.4.9.
Add one user nagios and one group nagcmd
$adduser nagios
(There is no need of assigning password to this user as this user is not going to login to the
system)
$groupadd nagcmd
Add user nagios and web server user apache to this group
(To know who is the owner of web server
$grep "^User" /etc/httpd/conf/httpd.conf
)
$usermod -G nagcmd nagios
$usermod -G nagcmd apache
$cd /usr/local/
Create one dir to hold all the nagios files
$ mkdir nagios
Change ownership of this dir to nagios
$chown -R nagios:nagios nagios
Untar the downloaded nagios tar file
$tar -xzf nagios-x.x.tar.gz
It will create one dir nagios-x.x inside the /usr/local
$cd nagios-x.x/
Configure the nagios and install
$./configure --prefix=/usr/local/nagios --with-cgiurl=/nagios/cgi-bin --with-htmurl=/nagios --with-nagios-user=nagios --with-nagios-group=nagios --with-command-group=nagcmd
$make all
$make install
$make install-init
$make install-commandmode
$make install-config
Installing Plugins
$ cd /usr/local
Untar the downloaded nagios plugin
$tar -xzf nagios-plugins-1.x.x.tar.gz
$cd nagios-plugins-1.x.x/
Configure the nagios plugin, and install plugins
$./configure --prefix=/usr/local/nagios
$make
$make install
Plugins will be installed at
/usr/local/nagios/libexec
Setup The Web Interface
Configure Aliases and Directory Options For The Web Interface
Add these line (at last) in the httpd.conf file (at /etc/httpd/conf dir)
ScriptAlias /nagios/cgi-bin /usr/local/nagios/sbin
Options ExecCGI
AllowOverride None
Order allow,deny
Allow from all
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
Alias /nagios /usr/local/nagios/share
Options None
AllowOverride None
Order allow,deny
Allow from all
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
Restart the webserver
$ /etc/init.d/httpd restart
Configure Web Authentication
$htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
(Enter the password)
Rename the config sample file
Nagios creates sample configurtion files at /usr/local/nagios/etc
Rename these files
$cd /usr/local/nagios/etc
$mv nagios.cfg-sample nagios.cfg
...and so on
Start nagios
$/etc/init.d/nagios start
After changing any config file check the main nagios.config
$ /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
It will display any syntax error in any config file with file name and line number, rectify the errors and reload the nagios.
$/etc/init.d/nagios reload
Point your browser at:
http://localhost/nagios
It will ask for apache authentication, supply the user: nagiosadmin and password
1. add one svn user and group
$ useradd svn -c "SVN Owner" -s /bin/false
(-c comment, -s shell , here no shell access)
2. If we want more than one repository then add group for each one.
$ groupadd reposgp
$ usermod -G reposgp svn
(Add this group to svn user/group)
3. Create a Subversion repository
We are creating it at /var ; svn will be the folder containing all repos
$ install -v -m 0755 -o svn -g svn -d /var/svn
$ svnadmin create --fs-type fsfs /var/svn/repos
(Here 'repos' will be our repos)
Now we can import some files/dir to the repos
$ svn import -m "Initial import." /path/to/source/tree
file:///var/svn/repos
Now change owner and group information on the repository, and add
an unprivileged user to the svn and reposgp groups:
$ chown -R svn:odotgp /var/svn/repos
$ chmod -R g+w /var/svn/repos
$ chmod g+s /var/svn/repos/db
$ usermod -G svn,repsogp sanjay
(here sanjay is already a user in the system)
We can verify the existing groups of user with the commands
$ groups sanjay
Syntax:
* * * * * command
# Use the hash sign to prefix a comment
# +---------------- minute (0 - 59)
# | +------------- hour (0 - 23)
# | | +---------- day of month (1 - 31)

Download latest stable Bugzilla from here
Untar the package at /var/www/html folder
$ tar -xzf bubzilla.x.x.tar.gz
Bugzilla's installation process is based on a script called checksetup.pl. The first thing it checks is whether you have appropriate versions of all the required Perl modules. The aim of this section is to pass this check. When it passes, proceed to Section 2.2.
To check you have the required modules, run:
bash# ./checksetup.pl --check-modules
checksetup.pl will print out a list of the required and optional Perl modules, together with the versions (if any) installed on your machine. The list of required modules is reasonably long; however, you may already have several of them installed
$ perl -MCPAN -e 'install "
Create one database in mysql with user/passord
Change the localcongif file of bugzilla (db related)
Run the
./checksetup.pl
Change the apache httpd.conf file add
AddHandler cgi-script .cgi
Options +Indexes +ExecCGI
DirectoryIndex index.cgi
