Deploy SVN by using svnserve

Procedure

• Step 1: Install SVN
• Step 2: Configure SVN
• Step 3: Use a Windows client to test the SVN service

Step 1: Install SVN

1. Connect to a Linux instance by using password authentication.
2. Run the following command to install SVN:

   yum install subversion

3. Run the following command to check the SVN version:

   svnserve --version

   

Step 2: Configure SVN

1. Run the following command to create a root directory for an SVN repository:

   mkdir /var/svn

2. Run the following commands in sequence to create an SVN repository.

   cd /var/svn

   svnadmin create /var/svn/svnrepos

3. Run the following commands in sequence to check the files that are automatically generated in the SVN repository:

   cd svnrepos

   ls

   

   The following table describes the SVN directories.

   Directory	Description
   db	Stores all version control data files.
   hooks	Stores hook scripts.
   locks	The client used to track access to the SVN repository.
   format	The text file that contains a single integer value which indicates the version number of the current SVN repository.
   conf	The configuration file of the SVN repository, which stores the usernames and permissions for accessing the repository.

4. Configure the username and password of the SVN repository.
   1. Run the cd conf/ command.
   2. Run the vi passwd command to open the configuration file.
   3. Press the I key to enter the edit mode.
   4. Move the pointer to [users] and add the username and password.
      Note You can add the username and password in the username = password format, such as userTest = passWDTest shown in the following figure. You must add a space before and after the equal sign (=).

      
   5. Press the Esc key to exit the edit mode, and enter :wq to save and close the file.
5. Configure the read and write permissions for the account.
   1. Run the vi authz command to open the access control file.
   2. Press the I key to enter the edit mode.
   3. Move the pointer to the end of the file and add the following code. In the code, userTest specifies the username, r specifies the read permission, and w specifies the write permission.

      [/]
      userTest=rw

      
   4. Press the Esc key to exit the edit mode, and enter :wq to save and close the file.
6. Modify the configurations of the SVN service.
   1. Run the vi svnserve.conf command to open the configuration file of the SVN service.
   2. Press the I key to enter the edit mode.
   3. Move the pointer to the following lines and delete the number sign (#) and space from the beginning of each line:
      Note Each line cannot start with a space. You must add a space before and after the equal sign (=).

      anon-access = read #Grants read permissions to anonymous users. You can also set anon-access to none to deny access by anonymous users. If you set anon-access to none, the revision history of the SVN service can show dates properly.
      auth-access = write #Grants write permissions.
      password-db = passwd #Specifies the password database file.
      authz-db = authz #Specifies the file that stores the authorization rules for path-based access control.
      realm = /var/svn/svnrepos #Specifies the authentication realm of the repository.

      
   4. Press the Esc key to exit the edit mode, and enter :wq to save and close the file.
7. Run the following command to start the SVN repository:
   The absolute path to the SVN repository is specified in the following example command:

   svnserve -d -r /var/svn/svnrepos/

   Note You can run the killall svnserve command to stop the SVN service.
8. Run the ps -ef |grep svn command to check whether the SVN service is started.
   A command output similar to the following one indicates that the SVN service is started.

Step 3: Use a Windows client to test the SVN service

1. Download and install the TortoiseSVN client on your local computer.
2. Right-click the blank area in the local project folder.
   In this example, the project folder is C:\KDR.
3. Select SVN Checkout... from the shortcut menu.
4. Configure the following settings and click OK:
   • In the URL of repository: field, enter the URL of the SVN repository from which to check out a working copy. In these examples, the SVN service is started by using the svnrepos repository and svnserve works only for the svnrepos repository. The URL of the SVN repository is in the format of svn://<Public IP address of the instance>.
   • In the Checkout directory: field, enter a directory to which to check out a working copy from the specified SVN repository. In this example, the directory is C:\Test.

   Note On you first logon, you must provide the username and password that you have configured in the passwd file.
