<h2>NAME</h2> | |
<div class="sectionbody"> | |
<p>git-daemon - | |
A really simple server for git repositories | |
</p> | |
</div> | |
</div> | |

</div> | |
<h2>DESCRIPTION</h2> | |
<div class="sectionbody"> | |
<p>A really simple TCP git daemon that normally listens on port "DEFAULT_GIT_PORT" | |
aka 9418. It waits for a connection asking for a service, and will serve | |
that service if it is enabled.</p> | |
<p>It verifies that the directory has the magic file "git-daemon-export-ok", and | |
it will refuse to export any git directory that hasn't explicitly been marked | |
for export this way (unless the <em>--export-all</em> parameter is specified). If you | |
pass some directory paths as <em>git-daemon</em> arguments, you can further restrict | |
the offers to a whitelist comprising of those.</p> | |
<p>By default, only <tt>upload-pack</tt> service is enabled, which serves | |
<tt>git-fetch-pack</tt> and <tt>git-peek-remote</tt> clients that are invoked | |
from <tt>git-fetch</tt>, <tt>git-ls-remote</tt>, and <tt>git-clone</tt>.</p> | |
<p>This is ideally suited for read-only updates, i.e., pulling from | |
git repositories.</p> | |
<p>An <tt>upload-archive</tt> also exists to serve <tt>git-archive</tt>.</p> | |
</div> | |
<h2>OPTIONS</h2> | |
<div class="sectionbody"> | |
<dl> | |
<dt> | |
--strict-paths | |
</dt> | |
<dd> | |
<p> | |
Match paths exactly (i.e. don't allow "/foo/repo" when the real path is | |
"/foo/repo.git" or "/foo/repo/.git") and don't do user-relative paths. | |
git-daemon will refuse to start when this option is enabled and no | |
whitelist is specified. | |
</p> | |
</dd> | |
<dt> | |
--base-path | |
</dt> | |
<dd> | |
<p> | |
Remap all the path requests as relative to the given path. | |
This is sort of "GIT root" - if you run git-daemon with | |
<em>--base-path=/srv/git</em> on example.com, then if you later try to pull | |
<em>git://example.com/hello.git</em>, <tt>git-daemon</tt> will interpret the path | |
as <em>/srv/git/hello.git</em>. | |
</p> | |
</dd> | |
<dt> | |
--base-path-relaxed | |
</dt> | |
<dd> | |
<p> | |
If --base-path is enabled and repo lookup fails, with this option | |
<tt>git-daemon</tt> will attempt to lookup without prefixing the base path. | |
This is useful for switching to --base-path usage, while still | |
allowing the old paths. | |
</p> | |
</dd> | |
<dt> | |
--interpolated-path=pathtemplate | |
</dt> | |
<dd> | |
<p> | |
To support virtual hosting, an interpolated path template can be | |
used to dynamically construct alternate paths. The template | |
supports %H for the target hostname as supplied by the client but | |
converted to all lowercase, %CH for the canonical hostname, | |
%IP for the server's IP address, %P for the port number, | |
and %D for the absolute path of the named repository. | |
After interpolation, the path is validated against the directory | |
whitelist. | |
</p> | |
</dd> | |
<dt> | |
--export-all | |
</dt> | |
<dd> | |
<p> | |
Allow pulling from all directories that look like GIT repositories | |
(have the <em>objects</em> and <em>refs</em> subdirectories), even if they | |
do not have the <em>git-daemon-export-ok</em> file. | |
</p> | |
</dd> | |
<dt> | |
--inetd | |
</dt> | |
<dd> | |
<p> | |
Have the server run as an inetd service. Implies --syslog. | |
Incompatible with --port, --listen, --user and --group options. | |
</p> | |
</dd> | |
<dt> | |
--listen=host_or_ipaddr | |
</dt> | |
<dd> | |
<p> | |
Listen on an a specific IP address or hostname. IP addresses can | |
be either an IPv4 address or an IPV6 address if supported. If IPv6 | |
is not supported, then --listen=hostname is also not supported and | |
--listen must be given an IPv4 address. | |
Incompatible with <em>--inetd</em> option. | |
</p> | |
</dd> | |
<dt> | |
--port=n | |
</dt> | |
<dd> | |
<p> | |
Listen on an alternative port. Incompatible with <em>--inetd</em> option. | |
</p> | |
</dd> | |
<dt> | |
--init-timeout | |
</dt> | |
<dd> | |
<p> | |
Timeout between the moment the connection is established and the | |
client request is received (typically a rather low value, since | |
that should be basically immediate). | |
</p> | |
</dd> | |
<dt> | |
--timeout | |
</dt> | |
<dd> | |
<p> | |
Timeout for specific client sub-requests. This includes the time | |
it takes for the server to process the sub-request and time spent | |
waiting for next client's request. | |
</p> | |
</dd> | |
<dt> | |
--syslog | |
</dt> | |
<dd> | |
<p> | |
Log to syslog instead of stderr. Note that this option does not imply | |
--verbose, thus by default only error conditions will be logged. | |
</p> | |
</dd> | |
<dt> | |
--user-path, --user-path=path | |
</dt> | |
<dd> | |
<p> | |
Allow ~user notation to be used in requests. When | |
specified with no parameter, requests to | |
git://host/~alice/foo is taken as a request to access | |
<em>foo</em> repository in the home directory of user <tt>alice</tt>. | |
If <tt>--user-path=path</tt> is specified, the same request is | |
taken as a request to access <tt>path/foo</tt> repository in | |
the home directory of user <tt>alice</tt>. | |
</p> | |
</dd> | |
<dt> | |
--verbose | |
</dt> | |
<dd> | |
<p> | |
Log details about the incoming connections and requested files. | |
</p> | |
</dd> | |
<dt> | |
--reuseaddr | |
</dt> | |
<dd> | |
<p> | |
Use SO_REUSEADDR when binding the listening socket. | |
This allows the server to restart without waiting for | |
old connections to time out. | |
</p> | |
</dd> | |
<dt> | |
--detach | |
</dt> | |
<dd> | |
<p> | |
Detach from the shell. Implies --syslog. | |
</p> | |
</dd> | |
<dt> | |
--pid-file=file | |
</dt> | |
<dd> | |
<p> | |
Save the process id in <em>file</em>. Ignored when the daemon | |
is run under <tt>--inetd</tt>. | |
</p> | |
</dd> | |
<dt> | |
--user=user, --group=group | |
</dt> | |
<dd> | |
<p> | |
Change daemon's uid and gid before entering the service loop. | |
When only <tt>--user</tt> is given without <tt>--group</tt>, the | |
primary group ID for the user is used. The values of | |
the option are given to <tt>getpwnam(3)</tt> and <tt>getgrnam(3)</tt> | |
and numeric IDs are not supported. | |
</p> | |
<p>Giving these options is an error when used with <tt>--inetd</tt>; use | |
the facility of inet daemon to achieve the same before spawning | |
<tt>git-daemon</tt> if needed.</p> | |
</dd> | |
<dt> | |
--enable=service, --disable=service | |
</dt> | |
<dd> | |
<p> | |
Enable/disable the service site-wide per default. Note | |
that a service disabled site-wide can still be enabled | |
per repository if it is marked overridable and the | |
repository enables the service with an configuration | |
item. | |
</p> | |
</dd> | |
<dt> | |
--allow-override=service, --forbid-override=service | |
</dt> | |
<dd> | |
<p> | |
Allow/forbid overriding the site-wide default with per | |
repository configuration. By default, all the services | |
are overridable. | |
</p> | |
</dd> | |
<dt> | |
<directory> | |
</dt> | |
<dd> | |
<p> | |
A directory to add to the whitelist of allowed directories. Unless | |
--strict-paths is specified this will also include subdirectories | |
of each named directory. | |
</p> | |
</dd> | |
</dl> | |
</div> | |
<h2>SERVICES</h2> | |
<div class="sectionbody"> | |
<p>These services can be globally enabled/disabled using the | |
command line options of this command. If a finer-grained | |
control is desired (e.g. to allow <tt>git-archive</tt> to be run | |
against only in a few selected repositories the daemon serves), | |
the per-repository configuration file can be used to enable or | |
disable them.</p> | |
<dl> | |
<dt> | |
upload-pack | |
</dt> | |
<dd> | |
<p> | |
This serves <tt>git-fetch-pack</tt> and <tt>git-peek-remote</tt> | |
clients. It is enabled by default, but a repository can | |
disable it by setting <tt>daemon.uploadpack</tt> configuration | |
item to <tt>false</tt>. | |
</p> | |
</dd> | |
<dt> | |
upload-archive | |
</dt> | |
<dd> | |
<p> | |
This serves <tt>git-archive --remote</tt>. It is disabled by | |
default, but a repository can enable it by setting | |
<tt>daemon.uploadarchive</tt> configuration item to <tt>true</tt>. | |
</p> | |
</dd> | |
<dt> | |
receive-pack | |
</dt> | |
<dd> | |
<p> | |
This serves <tt>git-send-pack</tt> clients, allowing anonymous | |
push. It is disabled by default, as there is _no_ | |
authentication in the protocol (in other words, anybody | |
can push anything into the repository, including removal | |
of refs). This is solely meant for a closed LAN setting | |
where everybody is friendly. This service can be | |
enabled by <tt>daemon.receivepack</tt> configuration item to | |
<tt>true</tt>. | |
</p> | |
</dd> | |
</dl> | |
</div> | |
<h2>EXAMPLES</h2> | |
<div class="sectionbody"> | |
<dl> | |
<dt> | |
We assume the following in /etc/services | |
</dt> | |
<dd> | |
<div class="listingblock"> | |
<div class="content"> | |
<pre><tt>$ grep 9418 /etc/services | |
git 9418/tcp # Git Version Control System</tt></pre> | |
</div></div> | |
</dd> | |
<dt> | |
git-daemon as inetd server | |
</dt> | |
<dd> | |
<p> | |
To set up <tt>git-daemon</tt> as an inetd service that handles any | |
repository under the whitelisted set of directories, /pub/foo | |
and /pub/bar, place an entry like the following into | |
/etc/inetd all on one line: | |
</p> | |
<div class="listingblock"> | |
<div class="content"> | |
<pre><tt> git stream tcp nowait nobody /usr/bin/git-daemon | |
git-daemon --inetd --verbose --export-all | |
/pub/foo /pub/bar</tt></pre> | |
</div></div> | |
</dd> | |
<dt> | |
git-daemon as inetd server for virtual hosts | |
</dt> | |
<dd> | |
<p> | |
To set up <tt>git-daemon</tt> as an inetd service that handles | |
repositories for different virtual hosts, <tt>www.example.com</tt> | |
and <tt>www.example.org</tt>, place an entry like the following into | |
<tt>/etc/inetd</tt> all on one line: | |
</p> | |
<div class="listingblock"> | |
<div class="content"> | |
<pre><tt> git stream tcp nowait nobody /usr/bin/git-daemon | |
git-daemon --inetd --verbose --export-all | |
--interpolated-path=/pub/%H%D | |
/pub/www.example.org/software | |
/pub/www.example.com/software | |
/software</tt></pre> | |
</div></div> | |
<p>In this example, the root-level directory <tt>/pub</tt> will contain | |
a subdirectory for each virtual host name supported. | |
Further, both hosts advertise repositories simply as | |
<tt>git://www.example.com/software/repo.git</tt>. For pre-1.4.0 | |
clients, a symlink from <tt>/software</tt> into the appropriate | |
default repository could be made as well.</p> | |
</dd> | |
<dt> | |
git-daemon as regular daemon for virtual hosts | |
</dt> | |
<dd> | |
<p> | |
To set up <tt>git-daemon</tt> as a regular, non-inetd service that | |
handles repositories for multiple virtual hosts based on | |
their IP addresses, start the daemon like this: | |
</p> | |
<div class="listingblock"> | |
<div class="content"> | |
<pre><tt> git-daemon --verbose --export-all | |
--interpolated-path=/pub/%IP/%D | |
/pub/192.168.1.200/software | |
/pub/10.10.220.23/software</tt></pre> | |
</div></div> | |
<p>In this example, the root-level directory <tt>/pub</tt> will contain | |
a subdirectory for each virtual host IP address supported. | |
Repositories can still be accessed by hostname though, assuming | |
they correspond to these IP addresses.</p> | |
</dd> | |
<dt> | |
selectively enable/disable services per repository | |
</dt> | |
<dd> | |
<p> | |
To enable <tt>git-archive --remote</tt> and disable <tt>git-fetch</tt> against | |
a repository, have the following in the configuration file in the | |
repository (that is the file <em>config</em> next to <em>HEAD</em>, <em>refs</em> and | |
<em>objects</em>). | |
</p> | |
<div class="listingblock"> | |
<div class="content"> | |
<pre><tt> [daemon] | |
uploadpack = false | |
uploadarchive = true</tt></pre> | |
</div></div> | |
</dd> | |
