hg repository 有多种的发布方式，前面我讲到过hg serve，这次主要写一下hgweb，它可以做到像http://xenbits.xen.org/hg/ 这样的效果。
新版的hgweb.cgi支持多个repository的发布了（我目前就是使用的hgweb.cgi），如果是比较老的Mercurial，就需要使用hgwebdir.cgi才能支持多个repository。我刚好使用过Mercurial的1.6.4和较老的1.4.3版本（是RHEL6.2自带的，我使用hgwebdir.cgi）。新老两种方法都分别介绍一下吧。
Mercurial可以从这里下载：http://mercurial.selenic.com/release/?M=D
新的Mercurial使用hgweb.cgi
1. 安装Mercurial： （略）
找到source code中的hgweb.cgi这个文件，将其copy到/var/www/hgweb/下。
2. 配置Web Server：以Apache为例
vim /etc/httpd/conf/httpd.conf 添加如下一行
ScriptAlias /hg “/var/www/hgweb/hgweb.cgi”
在/var/www/hgweb目录下，配置rewrite规则，vim .htaccess 做如下配置
1 2 3 4 5 6 7 8 9 10 11 12 13 | # Taken from http://www.pmwiki.org/wiki/Cookbook/CleanUrls#samedir # Used at http://ggap.sf.net/hg/ Options +ExecCGI RewriteEngine On #write base depending on where the base url lives RewriteBase /hg RewriteRule ^$ hgweb.cgi [L] # Send requests for files that exist to those files. RewriteCond %{REQUEST_FILENAME} !-f # Send requests for directories that exist to those directories. RewriteCond %{REQUEST_FILENAME} !-d # Send requests to hgweb.cgi, appending the rest of url. RewriteRule (.*) hgweb.cgi/$1 [QSA,L] |
3. 配置hgweb.cgi及其配置文件：
vim /var/www/hgweb/hgweb.cgi 做如下配置：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | #!/usr/bin/env python # # An example hgweb CGI script, edit as necessary # See also http://mercurial.selenic.com/wiki/PublishingRepositories # Path to repo or hgweb config to serve (see 'hg help hgweb') config = "/etc/hgweb.config" # Uncomment and adjust if Mercurial is not installed system-wide: #import sys; sys.path.insert(0, "/path/to/python/lib") # Uncomment to send python tracebacks to the browser if an error occurs: #import cgitb; cgitb.enable() from mercurial import demandimport; demandimport.enable() from mercurial.hgweb import hgweb, wsgicgi application = hgweb(config) wsgicgi.launch(application) |
vim /etc/hgweb.config 做如下配置：
1 2 3 | [paths] xen-unstable.hg = /home/repo/pub/xen-unstable.hg xen-unstable-staging.hg = /home/repo/pub/xen-unstable-staging.hg |
4. 重启Web Server 即可
5. 使用repository：浏览器访问：http://vt-repo/hg/
client端执行命令：hg clone http://vt-repo/hg/xen-unstable.hg xen-unstable.hg
老的Mercurial使用hgwebdir.cgi
其使用方法和上面新的hgweb.cgi是类似的了。
1. vim httpd.conf
ScriptAlias /hg “/var/www/hgweb/hgwebdir.cgi”
vim /var/www/hgweb/.htaccess
1 2 3 4 5 6 7 8 9 10 11 12 13 | # Taken from http://www.pmwiki.org/wiki/Cookbook/CleanUrls#samedir # Used at http://ggap.sf.net/hg/ Options +ExecCGI RewriteEngine On #write base depending on where the base url lives RewriteBase /hg RewriteRule ^$ hgwebdir.cgi [L] # Send requests for files that exist to those files. RewriteCond %{REQUEST_FILENAME} !-f # Send requests for directories that exist to those directories. RewriteCond %{REQUEST_FILENAME} !-d # Send requests to hgwebdir.cgi, appending the rest of url. RewriteRule (.*) hgwebdir.cgi/$1 [QSA,L] |
2. vim hgwebdir.cgi 配置
1 2 | application = hgwebdir('/etc/hgweb.config') wsgicgi.launch(application) |
vim /etc/hgweb.config 配置
[paths]
xen-unstable.hg = /home/repo/pub/xen-unstable.hg
xen-unstable-staging.hg = /home/repo/pub/xen-unstable-staging.hg
3. 重启Web Server
4. 使用方法就是一样的了
repository支持hg push的配置：
使用http/web方式push：在server端的repo中修改.hg/hgrc文件。
（或者修改your Web server user’s .hgrc file, such as /home/www-data/.hgrc, or a system-wide hgrc file like /etc/mercurial/hgrc）
添加如下配置信息：
1 2 3 | [web] push_ssl = false allow_push = * |
注意：以上配置皆为我在测试环境中的配置，请自己根据实际情况略作修改。运行Web Server的user一定要对repository有可读的权限（如果要push，则需要有读写权限）。
