Apache Svn Server

1: Install Apache HTTP server and required modules:

sudo apt-get install libapache2-svn apache2

2: Enable SSL

sudo a2enmod ssl
sudo vi /etc/apache2/ports.conf

Add or check that the following is in the file:

<IfModule mod_ssl.c>
    Listen 443
</IfModule>

3: Generate an SSL certificate:

sudo apt-get install ssl-cert
sudo mkdir /etc/apache2/ssl
sudo /usr/sbin/make-ssl-cert /usr/share/ssl-cert/ssleay.cnf /etc/apache2/ssl/apache.pem

4: Create virtual host

sudo cp /etc/apache2/sites-available/default /etc/apache2/sites-available/svnserver
sudo kate /etc/apache2/sites-available/svnserver

Change (in ports.conf):

"NameVirtualHost *" to "NameVirtualHost *:443"

and (in svnserver)

<VirtualHost *> to <VirtualHost *:443>

Add, under ServerAdmin (also in file svnserver):

SSLEngine on
SSLCertificateFile /etc/apache2/ssl/apache.pem
SSLProtocol all
SSLCipherSuite HIGH:MEDIUM

5: Enable the site:

sudo a2ensite svnserver
sudo /etc/init.d/apache2 restart

To overcome warnings:

sudo vi /etc/apache2/apache2.conf

Add: "ServerName $your_server_name"

Add, under ServerAdmin (also in file svnserver):

SSLEngine on
SSLCertificateFile /etc/apache2/ssl/apache.pem
SSLProtocol all
SSLCipherSuite HIGH:MEDIUM

6: Adding repository(ies): The following setup assumes we want to host multiple repositories. Run this for creating the first repository:

sudo mkdir /var/svn
sudo svnadmin create /var/svn/mysvnrepository
sudo chown -R www-data:www-data /var/svn/mysvnrepository
sudo chmod -R g+ws /var/svn/mysvnrepository<

6.a. For more repositories: do step 6 again (changing mysvnrepository Name)

7: Add an authenticated user

sudo htpasswd -c -m /etc/apache2/dav_svn.passwd $user_name

8: Enable and configure WebDAV and SVN:

sudo vi /etc/apache2/mods-available/dav_svn.conf

Add or uncomment:

<Location /svn>
DAV svn

# for multiple repositories - see comments in file
SVNParentPath /var/svn

AuthType Basic
AuthName "Subversion Repository"
AuthUserFile /etc/apache2/dav_svn.passwd
Require valid-user
SSLRequireSSL
</Location>

9: Restart apache server:

sudo /etc/init.d/apache2 restart

10: Validation:

Fired up a browser:

http://localhost/svn/$REPOS https://localhost/svn/$REPOS

Commit something:

svn import --username $user_name anyfile.txt https://localhost/svn/$REPOS/anyfile.txt -m “Testing”

Accept the certificate and enter password. Check out what you've just committed:

svn co --username $user_name https://localhost/svn/$REPOS

Server Setup

Open DKIM

Web site [1] For each domain:

• Create folder

  mkdir /etc/opendkim/keys/domain_name 

• Update configuration file /etc/opendkim/KeyTable
• Generate Key

  opendkim-genkey -s mail -d domain_name

• Change Owner

  chown opendkim: /etc/opendkim/KeyTable/domaine_name/mail.private

• Copy the key (mail.txt) into the dns record.
