First you need to install the CVS package. On Redhat Linux use:
cd /mnt/cdrom/Redhat/RPMS rpm -i rcs*.rpm rpm -i cvs*.rpm rpm -i openssh*.rpm To see the list of files installed do - rpm -qpl cvs*.rpm | less
The Openssh is required if you want to use ssh (Secure Shell) with CVS.
On other flavors of Unix, you may need to download the RCS and CVS tar balls and follow the README, INSTALL files to setup CVS. Visit http://www.cyclic.com and http://www.loria.fr/~molli/cvs-index.html
The following environment variables need to be setup in /etc/profile - default values required for all users. If not set in /etc/profile, then you should add these to your local profile file /.bash_profile.
export EDITOR=/bin/vi export CVSROOT=/home/cvsroot # WARNING!! WARNING: If you set CVSREAD to yes, checkout and update will try hard to # make the files in your working directory read-only. When this is not set, # the default behavior is to permit modification of your working files. #export CVSREAD=yes
# File ~/.bash_profile # Overriding env variables by resetting export EDITOR=/usr/bin/emacs export CVSROOT=/home/someotherdir/java/cvsroot
Create a directory to store the source code repository and give read, write access to Unix group/user. Also make sure that the directory name of CVSROOT does not contain any blank spaces. For example CVSROOT should not be like '/home/my rootcvs'.
bash$ su - root bash# export CVSROOT=/home/cvsroot bash# groupadd --help bash# groupadd cvs bash# useradd --help bash# useradd -g cvs -d $CVSROOT cvs bash# mkdir $CVSROOT bash# ls -ld $CVSROOT ... (you should see the listing) bash# chgrp -R cvs $CVSROOT bash# chmod o-rwx $CVSROOT bash# chmod ug+rwx $CVSROOT # To initialize the CVS repository and to put in source code files # do (but requires env CVSROOT to be set) : bash# cvs init # Add the unix users to the cvs group. Create supplementary groups for users. # Note that you MUST not put any blank spaces after comma separating the # group names in -G option. # In example below user tom belongs to groups cvs, users and staff and user # johnson belongs to group cvs only. bash# usermod --help bash# usermod -G cvs some_unix_username bash# usermod -G cvs,users,staff tom bash# usermod -G cvs,users,staroffice billclinton bash# usermod -G cvs johnson bash# exit .... (logout of root superuser mode) # Login as a user and import files into cvs.... bash$ su - billclinton bash$ export EDITOR=/bin/vi bash$ export CVSROOT=/home/cvsroot # WARNING! WARNING: If you set CVSREAD to yes, checkout and update will try hard to # make the files in your working directory read-only. When this is not set, # the default behavior is to permit modification of your working files. bash$ export CVSREAD=yes # Change directory is a must (MANDATORY) bash$ cd $HOME/somedir/anotherdir/directory/my_source_code_dir # Must give vendor tag and revision tag cvs import somedir/anotherdir/directory/my_source_code_dir vendor_1_0 rev_1_0 # Also note that it is very important to give the directory tree starting # from the $HOME, that is, in above example starting from somedir. # For example I did: bash$ cd $HOME/howto/foobar bash$ cvs import howto/foobar vendor_1_0 rev_1_0 # Another example is: bash$ cd $HOME/javafilesdir bash$ cvs import javafilesdir vendor_1_0 rev_1_0 # A sample testing and verification: bash$ cd $HOME/howto/foobar bash$ cvs checkout myfoo.java
TROUBLESHOOTING: When doing checkout it says module is unknown. It is a common mistake not to change directory while doing cvs import. You MUST change directory to the source-code-directory and then do cvs import. For example:
bash$ cd $HOME/somedirectory/foobardir bash$ cvs import somedirectory/foobardir vendor_1_0 rev_1_0
On client boxes where you want to use the CVS, you should install cvs packages and ssh package (if you want to use ssh). Setup the environment variables:
bash$ export CVSROOT=":ext:developer@cvs_server_box.domain.com:/home/cvsroot" bash$ export CVS_RSH="ssh"
bash$ export CVSROOT=:pserver:email@example.com:/cvsroot bash$ export CVS_RSH="ssh"
To migrate the existing RCS files to CVS, use the following script from downloadsoftware . Make sure that you installed the Korn shell package pdksh*.rpm from the Linux contrib cdrom.
NOTE : Get the Korn shell /bin/ksh by installing pdksh*.rpm from the Linux contrib cdrom
Now the RCS is migrated to CVS as 'project'. You can start using the CVS commands on module 'project'.
