Mercurial仓库架设

Mercurial是使用python编写的，因此需要安装python包管理器，常见的包管理器有easy install和pip。个人推荐使用pip，因为pip比easy install更成熟，不会出现某个python模块安装不完整，导致无法卸载也无法重新安装的问题。

安装easy install

1

sudo apt-get install python-setuptools

用easy install安装pip 

1

sudo easy_install pip

在安装mercurial之前, 需要先安装gcc等编译工具，以及python的开发支持库

1

sudo apt-get install build-essential python-dev

安装mercurial

1

sudo pip install mercurial

到目前为止mercurial已经安装完成了，命令行下输入”hg”就可以看到mercurial的help信息了。接下来配置一个mercurial的公共仓库，方便代码共享。

平时我的开发网站放在/web目录下面，比如域名为demo.example.com的网站，物理路径是/web/demo.example.com

首先初始化一个mercurial的仓库

1

mkdir /web/demo.example.com && cd /web/demo.example.com && hg init

接下来使用hgweb的wsgi脚本配置一个服务，详细信息可以参考: http://mercurial.selenic.com/wiki/PublishingRepositories#hgweb

个人喜欢gunicorn作为python app的WSGI服务器，因此先安装gunicorn

1

sudo pip install gunicorn

/web/hgweb.py (wsgi脚本)

# An example WSGI for use with mod_wsgi, edit as necessary
# See http://mercurial.selenic.com/wiki/modwsgi for more information

# Path to repo or hgweb config to serve (see 'hg help hgweb')
config = "/web/hgweb.config"

# Uncomment and adjust if Mercurial is not installed system-wide
# (consult "installed modules" path from 'hg debuginstall'):
#import sys; sys.path.insert(0, "/path/to/python/lib")

# Uncomment to send python tracebacks to the browser if an error occurs:
import cgitb; cgitb.enable()

# enable demandloading to reduce startup time
from mercurial import demandimport; demandimport.enable()

from mercurial.hgweb import hgweb
application = hgweb(config)

/web/hgweb.config 配置文件

[paths]
/ = /web/*

[web]
style = monoblue
push_ssl = false
allow_push = *

绑定hgrepos.example.com到开发环境IP
gunicorn —workers=2 hgweb:application —bind=0.0.0.0:8001 启动guincorn服务器看看

可以看到前面建立的仓库demo.example.com，成功的列出了。

下面使用apache代理gunicorn的请求，首先启用代理模块

LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy.so
LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so

配置apache虚拟主机 hgrepos.example.com.conf (apache2.4需要 “Require all granted”, 详细信息见http://httpd.apache.org/docs/2.4/upgrading.html)
