通过nginx git-http-backend 部署git 仓库

Intro

需要一下简易的内部Git服务供给给发布系统，gitlab的话太重了所以才有了以下方案

选型

centos 6
git http-backend
fcgiwrap
nginx
需注意使用bare repo交互
salt(可选，用于发布系统)

git http-backend

假如直接yum,的话一般在/usr/lib/git-core/,或者/usr/libexec/git-core下面

fcgiwrap

install

get source:

cd /usr/local/src/
git clone git://github.com/gnosek/fcgiwrap.git

compile:

cd /usr/local/src/fcgiwrap
autoreconf -i
./configure
make
mv fcgiwrap /usr/local/bin/

Init script

/etc/init.d/fcgiwrap

#!/usr/bin/perl
use strict;
use warnings FATAL => qw( all );

use IO::Socket::UNIX;

my $bin_path = '/usr/local/bin/fcgiwrap';
my $socket_path = $ARGV[0] || '/tmp/cgi.sock';
my $num_children = $ARGV[1] || 1;

close STDIN;

unlink $socket_path;
my $socket = IO::Socket::UNIX->new(
    Local => $socket_path,
    Listen => 100,
);

die "Cannot create socket at $socket_path: $!\n" unless $socket;

for (1 .. $num_children) {
    my $pid = fork;
    die "Cannot fork: $!" unless defined $pid;
    next if $pid;

    exec $bin_path;
    die "Failed to exec $bin_path: $!\n";
}

Don’t forget chmod +x /etc/init.d/fcgiwrap

/etc/rc.local

sudo -u www /etc/init.d/fcgiwrap to /etc/rc.local , www is your nginx user

usage

fastcgi_pass unix:/tmp/cgi.sock

Config nginx

nginx　server 配置

server {
    listen       80;
    server_name  git.example.com;

    auth_basic            "Restricted";
    auth_basic_user_file  /path/htpasswd;

    location ~ /git(/.*) {
        # fcgiwrap is set up to listen on this host:port
        fastcgi_pass unix:/tmp/cgi.sock;
        include       fastcgi_params;
        fastcgi_param SCRIPT_FILENAME     /usr/libexec/git-core/git-http-backend;
        # export all repositories under GIT_PROJECT_ROOT
        fastcgi_param GIT_HTTP_EXPORT_ALL "";
        fastcgi_param GIT_PROJECT_ROOT    /path1/git;
        fastcgi_param PATH_INFO           $1;
        fastcgi_param   REMOTE_USER     $remote_user;

    }
}

生成htpasswd
```
htpasswd -c /path/htpasswd user
```

测试

生成bare git repo

cd /path1/git/
mkdir my-repo
cd my-repo
git --bare init

git clone

git clone http://git.example.com/git/my-repo

make commit

date >> readme.md ; git add * ; git commit -m "first commit"

注意，全程中用户要用你nginx的work进程用户　，比如html ,www 之类的
