Looking to Hire Python Developers India<\/a>?<\/p>\n

A.Dependencies
\n1<\/strong>.Basic
\n1.1.Python 2.5 or higher
\n1.2.Setup tools
\n1.3.Genshi
\n1.4.sqlite database
\nNote:-<\/strong>
\n1.1.Python2.4 is already installed with centOS.It does not support full swing operation of Trac.So install “virtualenv” python<\/a> tool.Get the tar ball from\u00a0 http:\/\/pypi.python.org\/pypi\/virtualenv<\/a><\/strong>.Just untar it,get into the directory and do Hire Python Developers India<\/p>\n

[bash] #python setup.py install [\/bash]<\/p>\n

Now it’ll be installed(Python2.7 will be automatically installed with it)!Then create an environment by<\/p>\n

[bash]#python virtualenv.py ENV[\/bash]
\n[bash]#virtualenv ENV[\/bash]<\/p>\n

Done!!!<\/p>\n

Note<\/strong>:-Now new binaries will be available under ‘\/root\/ENV\/bin<\/strong>‘. We’re going to use commands from this directory for further.<\/p>\n

Activate the new virtual environment by<\/p>\n

[bash]#source .\/ENV\/bin\/activate[\/bash]<\/p>\n

(Here ENV is the virtual environment)<\/p>\n

From now onwards,it’ll take commands from virtual environment itself if available! Otherwise it will go for default system binaries! If you want to return to the real environment, trigger<\/p>\n

[bash]#deactivate[\/bash]<\/p>\n

1.2.Setup tools
\nThis will be installed automatically along the installation of ‘virtualenv’.
\n1.3.Install Genshi by<\/p>\n

[bash]#easy_install Genshi[\/bash]<\/p>\n

1.4.Sqlite can be installed using ‘yum’.Install ‘devel’ for sqlite also!<\/p>\n

2<\/strong>.mod_wsgi module for apache
\nFor compiling mod_wsgi with apache,simply follow the instructions given in: http:\/\/code.google.com\/p\/modwsgi\/wiki\/QuickInstallationGuide<\/a><\/strong><\/p>\n

B.Installing Trac<\/strong><\/p>\n

[bash]#easy_install Babel==0.9.5
\n#easy_install Trac
\n#easy_install -U Trac
\n#easy_install -U Trac==dev[\/bash]<\/p>\n

C.Creating a project environment<\/strong><\/p>\n

1<\/strong>.Before you proceed,create a directory for keeping trac project files under a directory accessible to apache.(Here default path is used)<\/p>\n

[bash]#mkdir \/var\/www\/trac[\/bash]<\/p>\n

Now make sure apache user can access all the directories and files under ‘trac’<\/p>\n

[bash]#chown -R apache.apache \/var\/www\/trac[\/bash]<\/p>\n

2<\/strong>.Create an environment<\/p>\n

[bash]#trac-admin \/var\/www\/myproject initenv[\/bash]<\/p>\n

Enter the name of project and database when you are prompted for. Leave database name as default if you wish to use the default database!<\/p>\n

D.Deploying Trac<\/strong><\/p>\n

[bash]#tracd –port 8000 \/var\/www\/trac\/myproject[\/bash]<\/p>\n

(include ‘-s’ for single instance)<\/p>\n

Now open browser and go to : http:\/\/localhost:8000 . Trac web-based interface will be appeared!<\/p>\n

E.Granting admin rights to admin user<\/strong><\/p>\n

[bash]#trac-admin \/var\/www\/myproject permission add admin TRAC_ADMIN[\/bash]<\/p>\n

Warning<\/strong>:- If you failed to activate virtual environment as described under section A-1.1, you will need to specify path for all the commands (For eg:\/root\/ENV\/bin easy_install) and you may encounter an error ”\u00a0 File “\/usr\/lib\/python2.4\/site-packages\/_xmlplus\/parsers\/expat.py”, line 4, in <module> from pyexpat import * ImportError: \/usr\/lib\/python2.4\/site-packages\/_xmlplus\/parsers\/pyexpat.so: undefined symbol: PyUnicodeUCS4_Decode”. “.<\/p>\n

For resolving this,trigger<\/p>\n

[bash]#export\u00a0 PYTHONPATH=\/path\/to\/lib\/python2.7\/site-packages\/[\/bash]<\/p>\n

on each shell or edit files like \/etc\/profile or \/etc\/bashrc etc to take a permanent effect. But,this is not recommended and you should activate the virtual environment instead (see<\/em> A-1.1) to avoid this scenario!!\u00a0 Happy doing \ud83d\ude42<\/p>\n
