HOW TO INSTALL SUBVERSION WITH APACHE ON LINUX (svn server)

• Log as root user in to your system

[root@pasindu ~]# yum search subversion

• We need to install following packages .

subversion-devel.i686
subversion.i686
subversion-libs.i686


[root@pasindu ~]# yum install subversion-devel subversion-libs subversion

Your subversion installation done. Now we have to configure subversion Apache compatibility using mod_dav_svn. we assume  Apache server already installed .
if not  ...  [root@pasindu svn]# yum insatll http


After that we need to install mod_dav_svn package to our Apache server 

[root@pasindu ~]#yum install mod_dav_svn

• configuring Apache Server

[root@pasindu ~]# vim /etc/httpd/conf/httpd.conf
add following two lines
LoadModule dav_svn_module modules/mod_dav_svn.so
LoadModule authz_svn_module modules/mod_authz_svn.so 
Make sure you will add these lines after LoadModule dav_module


[root@pasindu ~]# /etc/init.d/httpd configtest
[root@pasindu ~]# /etc/init.d/httpd restart

• Creating svn repos using  svnadmin command 

[root@pasindu var]# svnadmin create repos
[root@pasindu var]# ls -aslt | grep repos
4 drwxr-xr-x   6 root root  4096 Jan 26 12:02 repos  
[root@pasindu var]# ls repos/
conf  db  format  hooks  locks  README.txt
[root@pasindu var]# chown apache:apache /var/repos

• Then at the end of the httpd.conf file you have to add

[root@pasindu var]# vim /etc/httpd/conf/httpd.conf
#for svn path
<Location /svn/repos>
DAV svn
SVNPath /var/repos
<Location>

[root@pasindu ~]# /etc/init.d/httpd configtest
[root@pasindu ~]# /etc/init.d/httpd restart

• configuring  Authentication 

[root@pasindu var]# htpasswd -cm /var/svn/svnuser pasindu
htpasswd: cannot create file /var/svn/svnuser
[root@pasindu var]# mkdir /var/svn
[root@pasindu var]# htpasswd -cm /var/svn/svnuser pasindu
New password:
Re-type new password:
Adding password for user pasindu

• Configuring svn policy files 

[root@pasindu var]# vim svn/svnpolicy


[/]
* = rw


You can specify this inside httpd.conf file as,
<Location /svn/repos>
DAV svn
SVNPath /var/repos
AuthzSVNAccessFile /var/svn/svnpolicy
AuthType Basic
AuthName "Subversion repository"
AuthUserFile /var/svn/svnuser
Require user user_name
</Location>



[root@pasindu ~]# /etc/init.d/httpd configtest
[root@pasindu svn]# /etc/init.d/httpd restart

IP Addresses

IP Addresses Explained

IP Address (Internet Protocol Address): This number is an exclusive number all information technology devices (printers, routers, modems, et al) use which identifies and allows them the ability to communicate with each other on a computer network. There is a standard of communication which is called an Internet Protocol standard (IP). In laymans terms it is the same as your home address. In order for you to receive snail mail at home the sending party must have your correct mailing address (IP address) in your town (network) or you do not receive bills, pizza coupons or your tax refund. The same is true for all equipment on the internet. Without this specific address, information cannot be received. IP addresses may either be assigned permanently for an Email server/Business server or a permanent home resident or temporarily, from a pool of available addresses (first come first serve) from your Internet Service Provider. A permanent number may not be available in all areas and may cost extra so be sure to ask your ISP.
