== Installation ==
  
02) su to root
+
Update or install to the latest version of cvs and xinetd (as root):
 +
# pacman -S cvs xinetd
  
 +
Create the cvs group - members of this group will have write access to the repository (as root):
 +
# groupadd cvs
  
03) Make sure you have the latest version of CVS
+
Create the cvs user in the cvs group (-md makes the home directory) (as root):
  pacman -Sy cvs
+
  # useradd -md /home/cvsroot -g cvs -p Insecure0 cvs
  
 +
== Initialization ==
  
04) Make sure you have the latest version of xinetd
+
Initialize your CVS repository (as cvs):
  pacman -S xinetd
+
  cvs% cvs -d /home/cvsroot init
  
 +
The permissions on the directory (not the files inside, however) should be 2775 (drwxrwxr-x), but if not, run (as cvs):
 +
cvs% chmod 2775 /home/cvsroot
  
05) Now create the directory that will become your CVS repository.
+
Add any users that you want to have local access to the repository to the group cvs by using the following two steps. The 'adduser' script is very handy.
mkdir /home/cvsroot
+
  
 +
You can add pre-existing users to the cvs group with the command (as root):
 +
# gpasswd -a username cvs
  
06) Initialize your CVS repository
+
Make a file in {{ic|/etc/xinetd.d/}} called cvspserver with these contents (as root):
cvs init -d /home/cvsroot
+
 
+
 
+
07) Create a group called cvs - members of this group will have write access to the repository
+
groupadd cvs
+
 
+
 
+
08) Create a user named cvs
+
useradd -d /home -g cvs -p password cvs
+
 
+
 
+
09) Set the owner and group of the repository
+
chown -R cvs:cvs /home/cvsroot
+
 
+
 
+
10) Set the proper permissions for the repository(set group ID, owner: read write execute, group: read write execute, others: read execute)
+
chmod 2775 /home/cvsroot
+
 
+
 
+
Add any users that you want to have local access to the repository to the group cvs by using the following two steps.
+
 
+
 
+
11) Get a list of the groups for a user.
+
groups someuser
+
 
+
 
+
12) Set the groups for the user. The group1 group2 etc. are the groups you got from the previous step. '''NOTE: make sure not to use spaces when listing the additional groups'''
+
usermod -g users -G group1,group2,group3,cvs someuser
+
 
+
 
+
13) Make a file in /etc/xinetd.d/ called cvspserver with these contents:
+
  
 
  service cvspserver
 
  service cvspserver
Line 65: Line 42:
 
  }
 
  }
  
14) Edit /etc/services and add cvspserver service if does not exist:
+
Edit {{ic|/etc/services}} and add this line containing the information for cvspserver service if does not exist (as root):
  cvspserver 2401/tcp #CVS PServer
+
  cvspserver 2401/tcp     #CVS PServer
  
 +
Now restart xinetd (as root):
 +
/etc/rc.d/xinetd restart
  
15) Create some files in CVSROOT
+
== Configuration ==
  /home/cvsroot/CVSROOT/passwd  # user and passwd, refer to the following
+
 
+
  anonymous::
+
  lnzju:YKy0EJBP5vDpY:cvs
+
  
 +
Become cvs ("su cvs") and create a 'passwd' file in {{ic|~/CVSROOT}}. To add entries in the file you can use htpasswd command (present in the apache package) like that:
  
  /home/cvsroot/CVSROOT/writers #  users that have write permission of the repository,every user take a newline
+
  htpasswd -b filename username password
  lnzju
+
  /home/cvsroot/CVSROOT/readers  #  users that have read permission of the repository,every user take a newline
+
  anonymous
+
  
16)Allow clients to connect to the Server
+
then edit che file and add che group, should look like this:
edit /etc/hosts.allow ,add a newline ,as the following
+
 
 +
# Format is username:password:group
 
   
 
   
  cvs:ALL
+
anonymous::
 +
luser:HopefullySecure0:cvs
 +
other:Insecure0:cvs
  
 +
Now create a 'writers' file in {{ic|~/CVSROOT}}, which grants write privileges to the users you created in 'passwd':
 +
luser
 +
other
  
17) You must unset the variable HOME before you restart xinetd
+
Now create a 'readers' file in {{ic|~/CVSROOT}}, which grants read privileges to the users you created in 'passwd':
  unset HOME
+
  anonymous
  
 +
{{note|If a user is present in the readers file cannot have write access too.}}

== Use ==
/etc/rc.d/xinetd restart

"Concurrent Versions System is a version control system, an important component of Source Configuration Management (SCM). Using it, you can record the history of sources files, and documents. It fills a similar role to the free software RCS, PRCS, and Aegis packages."

This is a quick guide on how to set up the latest CVS server.

Installation

Update or install to the latest version of cvs and xinetd (as root):

# pacman -S cvs xinetd

Create the cvs group - members of this group will have write access to the repository (as root):

# groupadd cvs

Create the cvs user in the cvs group (-md makes the home directory) (as root):

# useradd -md /home/cvsroot -g cvs -p Insecure0 cvs

Initialization

Initialize your CVS repository (as cvs):

cvs% cvs -d /home/cvsroot init

The permissions on the directory (not the files inside, however) should be 2775 (drwxrwxr-x), but if not, run (as cvs):

cvs% chmod 2775 /home/cvsroot

Add any users that you want to have local access to the repository to the group cvs by using the following two steps. The 'adduser' script is very handy.

You can add pre-existing users to the cvs group with the command (as root):

# gpasswd -a username cvs

Make a file in /etc/xinetd.d/ called cvspserver with these contents (as root):

service cvspserver
{
        port            = 2401
        socket_type     = stream
        protocol        = tcp
        wait            = no
        user            = root
        passenv         = /home/cvsroot
        server          = /usr/bin/cvs
        server_args     = -f --allow-root=/home/cvsroot pserver
}

Edit /etc/services and add this line containing the information for cvspserver service if does not exist (as root):

cvspserver 2401/tcp     #CVS PServer

Now restart xinetd (as root):

/etc/rc.d/xinetd restart

Configuration

Become cvs ("su cvs") and create a 'passwd' file in ~/CVSROOT. To add entries in the file you can use htpasswd command (present in the apache package) like that:

htpasswd -b filename username password

then edit che file and add che group, should look like this:

# Format is username:password:group

anonymous::
luser:HopefullySecure0:cvs
other:Insecure0:cvs

Now create a 'writers' file in ~/CVSROOT, which grants write privileges to the users you created in 'passwd':

luser
other

Now create a 'readers' file in ~/CVSROOT, which grants read privileges to the users you created in 'passwd':

anonymous
Note: If a user is present in the readers file cannot have write access too.

Use

You can test out the server using the following commands:

export CVSROOT=:pserver:my_user_name@127.0.0.1:/home/cvsroot
cvs login
mkdir ~/sandbox
mkdir ~/sandbox/myproject
cd ~/sandbox/myproject
echo "this is a sample file" > myfile
cvs import -m "description of myproject" myproject v1 r1
cd ..
rm -R myproject
cvs checkout myproject
cd myproject
echo "some changes to the file" >> myfile
cvs commit -m "Explain changes here" myfile
