Git: Setting up private server on CentOS via HTTP using git-http-backend

1. Install git and apache

Open terminal and run commands:

$yum install httpd git

Start apache

$apachectl start

2. Create users file

/etc/git-users

username:password
othername:otherpassword

If you don't know how to create that file then install nano editor:
$yum install nano
and create file
$nano /etc/git-users
enter content and press Ctr + O to save, Ctr + X to exit.

3. Create folder that you want to push git base in

$mkdir /var/www/git

4. Create apache config file

/etc/httpd/conf.d/git.conf

SetEnv GIT_PROJECT_ROOT /var/www/git
SetEnv GIT_HTTP_EXPORT_ALL
ScriptAlias /git/ /usr/libexec/git-core/git-http-backend/

RewriteCond %{QUERY_STRING} service=git-receive-pack [OR]
RewriteCond %{REQUEST_URI} /git-receive-pack$
RewriteRule ^/git/ - [E=AUTHREQUIRED:yes]

<LocationMatch "/git">
  Order Deny,Allow
  Deny from env=AUTHREQUIRED

  AuthType Basic
  AuthName "Git Access"
  AuthUserFile /etc/git-users
  Require valid-user
</LocationMatch>

If you don't know how to find apache config folder, use this command
$apachectl -V
For example we found that apache config file in /etc/httpd/conf/httpd.conf then we create file
/etc/httpd/conf.d/git.conf

Restart apache

$apachectl restart

5. Create git base

$cd /var/www/git # folder that we created in step 3
$mkdir test.git
$cd test.git
$git init --bare --shared

Open config file /var/www/git/test.git/config in git base then add this

[http]
 receivepack = true

6. Using

Access git server via http://your_server_ip_address/git/test.git with username and password set at step 2.
