If not, check whether apache started up +successfully. + + +Step 2: enable DAV on this repository +------------------------------------- + +First make sure the dav_module is loaded. For this, insert in httpd.conf: + + LoadModule dav_module libexec/httpd/libdav.so + AddModule mod_dav.c + +Also make sure that this line exists which is the file used for +locking DAV operations: + + DAVLockDB "/usr/local/apache2/temp/DAV.lock" + + On Debian these steps can be performed with: + + Enable the dav and dav_fs modules of apache: + $ a2enmod dav_fs + (just to be sure. dav_fs might be unneeded, I don't know) + $ a2enmod dav + The DAV lock is located in /etc/apache2/mods-available/dav_fs.conf: + DAVLockDB /var/lock/apache2/DAVLock + +Of course, it can point somewhere else, but the string is actually just a +prefix in some Apache configurations, and therefore the _directory_ has to +be writable by the user Apache runs as. + +Then, add something like this to your httpd.conf + + <Location /my-new-repo.git> + DAV on + AuthType Basic + AuthName "Git" + AuthUserFile /usr/local/apache2/conf/passwd.git + Require valid-user + </Location> + + On Debian: + Create (or add to) /etc/apache2/conf.d/git.conf : + + <Location /my-new-repo.git> + DAV on + AuthType Basic + AuthName "Git" + AuthUserFile /etc/apache2/passwd.git + Require valid-user + </Location> + + Debian automatically reads all files under /etc/apach2/conf.d. + +The password file can be somewhere else, but it has to be readable by +Apache and preferably not readable by the world. + +Create this file by + $ htpasswd -c /usr/local/apache2/conf/passwd.git <user> + + On Debian: + $ htpasswd -c /etc/apache2/passwd.git <user> + +You will be asked a password, and the file is created. Subsequent calls +to htpasswd should omit the '-c' option, since you want to append to the +existing file. + +You need to restart Apache. + +Now go to http://<username>@<servername>/my-new-repo.git in your +browser to check whether it asks for a password and accepts the right +password. + +On Debian: + + To test the WebDAV part, do: + + $ apt-get install litmus + $ litmus http://<servername>/my-new-repo.git <username> <password> + + Most tests should pass. + +A command line tool to test WebDAV is cadaver. + +If you're into Windows, from XP onwards Internet Explorer supports +WebDAV. For this, do Internet Explorer -> Open Location -> +http://<servername>/my-new-repo.git [x] Open as webfolder -> login . + + +Step 3: setup the client +------------------------ + +Make sure that you have HTTP support, i.e. your git was built with curl. +The easiest way to check is to look for the executable 'git-http-push'. + +Then, add the following to your $HOME/.netrc (you can do without, but will be +asked to input your password a _lot_ of times): + + machine <servername> + login <username> + password <password> + +...and set permissions: + chmod 600 ~/.netrc + +If you want to access the web-server by its IP, you have to type that in, +instead of the server name. + +To check whether all is OK, do: + + curl --netrc --location -v http://<username>@<servername>/my-new-repo.git/ + +...this should give a directory listing in HTML of /var/www/my-new-repo.git . + + +Now, add the remote in your existing repository which contains the project +you want to export: + + $ git-repo-config remote.upload.url \ + http://<username>@<servername>/my-new-repo.git/ + +It is important to put the last '/'; Without it, the server will send +a redirect which git-http-push does not (yet) understand, and git-http-push +will repeat the request infinitely. + + +Step 4: make the initial push +----------------------------- + +From your client repository, do + + $ git push upload master + +This pushes branch 'master' (which is assumed to be the branch you +want to export) to repository called 'upload', which we previously +defined with git-repo-config. + + +Troubleshooting: +---------------- + +If git-http-push says + + Error: no DAV locking support on remote repo http://... + +then it means the web-server did not accept your authentication.
