Trac installation with mod_python

Overview

Installing trac on a server with Apache and mod_python

Requirements

Tested with the below ,

Apache 2.2
Mysql 5.0

Objective

Installing trac and apache module mod_python for a project system on a domain subdirectory

Configuration

Step 1

Make sure that you have the required version of python , flew, setuptools and mysql-python installed.
This installation was done on a DirectAdmin server and it had python version as Python 2.4.3, so had to install a secondary python of version 2.5 on a different location

To install python 2.5

root@serv:~# cd /usr/local/src
root@serv:~# mkdir -p /usr/local/TRAC/PYTHON/
root@serv:~# wget http://www.python.org/ftp/python/2.5/Python-2.5.tgz
root@serv:~# tar -zxvf Python-2.5.tgz
root@serv:~# cd Python-2.5
root@serv:~# ./configure –enable-shared –prefix=/usr/local/TRAC/PYTHON/
root@serv:~# make
root@serv:~# make install

To install flex 2.5

root@serv:~# cd /usr/local/src
root@serv:~# wget http://sourceforge.net/projects/flex/files/flex/flex-2.5.35/flex-2.5.35.tar.gz/download?use_mirror=biznetnetworks
root@serv:~# tar -zxvf flex-2.5.35.tar.gz
root@serv:~# cd flex-2.5.35
root@serv:~# ./configure
root@serv:~# make
root@serv:~# make install

To install setup tools

root@serv:~# cd /usr/local/src
root@serv:~# wget http://peak.telecommunity.com/dist/ez_setup.py
root@serv:~# /usr/local/TRAC/PYTHON/bin/python ez_setup.py

To install mysql-python

root@serv:~# cd /usr/local/src
root@serv:~# wget http://sourceforge.net/projects/mysql-python/files/mysql-python/1.2.3/MySQL-python-1.2.3.tar.gz/download?use_mirror=biznetnetworks
root@serv:~# tar -zxvf MySQL-python-1.2.3.tar.gz
root@serv:~# cd MySQL-python-1.2.3
root@serv:~# /usr/local/TRAC/PYTHON/bin/python ./setup.py install

Step 2

Linking the libraries
As you have installed the python to a custom location you have to link the libraries so as properly compile the mod_python

root@serv:~# echo “/usr/local/TRAC/PYTHON/lib/” > /etc/ld.so.conf.d/python2.5.conf
root@serv:~# ldconfig -v

Step 3

Installing trac

root@serv:~# cd /usr/local/src
root@serv:~# wget http://ftp.edgewall.com/pub/trac/Trac-0.12.1.tar.gz
root@serv:~# tar -zxvf Trac-0.12.1.tar.gz
root@serv:~# cd Trac-0.12.1/
root@serv:~# /usr/local/TRAC/PYTHON/bin/python setup.py install

Step 4

Installing mod_python and loading the module
Please note to give the apxs and python binary path correctly according to the installed location.

root@serv:~# wget http://www.ecoficial.com/apachemirror//httpd/modpython/mod_python-3.3.1.tgz
root@serv:~# tar -zxvf mod_python-3.3.1.tgz
root@serv:~# cd mod_python-3.3.1/
root@serv:~# ./configure –with-apxs=/usr/sbin/apxs –with-python=/usr/local/TRAC/PYTHON/bin/python
root@serv:~# make
root@serv:~# make install

Please make sure that the module is loaded on the proper file which is included in apache conf or you can load the module directly in the main conf file ( httpd.conf )

root@serv:~# echo “LoadModule python_module /usr/lib/apache/mod_python.so” > /etc/httpd/conf/extra/httpd-python.conf

Step 5

Creating a project
Create a mysql db/db_user and grant all privileges to the database with a password

root@serv:~# /usr/local/TRAC/PYTHON/bin/trac-admin /var/project initenv desired_projectname mysql://db_user:db_pass@localhost:3306/db_name

Step 6

Setting up a Login
Limit the access with a login

root@serv:~# htpasswd -c /var/project/ .htpasswd admin

Step 7

Setup the VirtualHost
Open your Apache VirtualHost file and add the below lines into it

<Location /project>

RewriteEngine Off  ### to override any redirect rules on .htaccess of parent directory
SetHandler mod_python
PythonInterpreter main_interpreter
PythonHandler trac.web.modpython_frontend
PythonOption TracEnv /var/project
PythonOption TracUriRoot /project
AuthType Basic
AuthName “Trac”
AuthUserFile /var/project/.htpasswd
Require valid-user

</Location>

You will be able to access the project trac now using

http://your_domain.com/project

DirectAdmin migration

Overview

A how to for doing DirectAdmin to DirectAdmin server migration. This can assist you on  complete account migration from Oldserver to Newserver , with rsync, sysbackup and manual restoration.

Requirements

  • Basic idea of DireactAdmin files and directories
  • You must have a new server with DirectAdmin Licensed and installed
  • You must make sure that the version of Apache, php and mysql installed on both servers matches

Migration

DirectAdmin does have a utility called System Backup to backup all the needed configuration files and directories in the  server, but unfortunately it doesn’t come with a restoration tool. So we will have to do it in the manual way. Home directories will be synced and mysql databases will be backedup and restored  separately.

Step 1

Run System Backup on the old server.

System Backup

Admin Tools >> System Backup

 

We will be backuping home directories and mysql db’s manually so Uncheck and unselect the following options on System Backup

Add user home directories to directory list below

Backup httpd data

Backup MySQL Databases

Check and Select

Backup DNS data

Backup Directories and Files listed below

All directories/files listed in bottom section of the System Backup

now click on the Run System Backup Now icon . The backup will be stored mostly in /home/backup ( it will depend upon how you have set it in DA )

Step 2

rsync the system backup to the Newserver.

root@old:~# rsync -avurz -e ssh –delete /home/backup root@Newserver_IP:/home/backup

Step 3

On the Newserver restore the system backups one by one manually.

For example, for restoring your /etc/virtual directory,

root@new:~# cd /etc
root@new:~# tar xvzfp /home/backup/<backup_date>/custom/etc/virtual.tar.gz

Please check here for the complete paths and files used on a DirectAdmin system.

( Do take extra care while restoring /etc/passwd /etc/shadow /etc/group etc.. )

Step 4

Synchronise the home directory

root@old:~# rsync -avurz -e ssh –delete /home root@Newserver_IP:/home

Step 5

Backup and restore the mysql DB’s

On Oldserver

root@old:~# cat /usr/local/directadmin/conf/mysql.conf

Get the da_admin password from the above file

root@old:~# mysqldump -u da_admin -p  –all-databases > /root/all_databases.sql

root@old:~# scp /root/all_databases.sql root@Newserver_IP:/root

On Newserver

root@new:~# cat /usr/local/directadmin/conf/mysql.conf

root@new:~# mysql -u da_admin -p < /root/all_databases.sql

Step 6

Use the ipswap script to change the Oldserver IP’s

root@new:~# cd /usr/local/direactadmin/scripts/

root@new:~# ./ipswap.sh Oldserver_IP  Newserver_IP

Step 7

Update the nameservers to the Newserver IP’s.

Step 8

To resolve all the queries correctly to the new server . You will have to setup the multi server dns clustering on the new server

Multi Server Setup

on, Add Remote Server

Input the Oldserver IP , login :  admin and password

IP:

Port:

 

 

SSL:

 

 

Username:

Password:

 

 

Click Add

next on, List of External Servers

Zone Transfer:
Domain Check:

select the server

Click connections “Test Connection(s)”  to check the connection.

If the test runs OK, Turn Multi Server On on the top

and run the below to sync the zone files

root@new:~# echo “action=rewrite&value=named” >> /usr/local/directadmin/data/task.queue

Now you’ll be able to access the domains from the new server , do tail the logs to see if everything is fine :)
