Apache 上面运行 Asp.NET 配置与性能测试
昨天测试了一下在 Apache 下面部署 Asp.NET (3.5) 的网站，其实一开始就在想这东西效率应该不会好多少。后面经过多番测试的确是要比 IIS 慢许多。我是拿公司的项目做的测试，这是一个 Web2.0 网站，功能还是算比较多，很多种应用都有，除了一开始修改了一点点 Rewrite 以外，其它的功能完全能用，没发现任何问题。
先说一下我的安装过程：
Apache 的安装我这里就不说了
需要下载 mod_aspdotnet 这个 Apache Module
项目地址：http://sourceforge.net/projects/mod-aspdotnet
安装过程很简单，只要选对 Apache 的安装目录就好了，并且安装程序会自动发现 Apache 的安装位置的。
修改 httpd.conf (source)
# 添加 80 端口的监听 (得要把 IIS 停了，当然也可以换 8080 或其它，哪么下面的端口号也要跟着改)
Listen 80
# 添加 Module 引用
LoadModule aspdotnet_module modules/mod_aspdotnet.so
# 添加 Handler
AddHandler asp.net asax ascx ashx asmx aspx axd config cs csproj licx rem resources resx soap vb vbproj vsdisco webinfo
# 加入新的 关于 mod_aspdotnet 的 IfModule
<IfModule mod_aspdotnet.cpp>
# For all virtual ASP.NET webs, we need the aspnet_client files
# to serve the client-side helper scripts.
AliasMatch /aspnet_client/system_web/(\d+)_(\d+)_(\d+)_(\d+)/(.*) "C:/Windows/Microsoft.NET/Framework/v$1.$2.$3/ASP.NETClientFiles/$4"
<Directory "C:/Windows/Microsoft.NET/Framework/v*/ASP.NETClientFiles">
Options FollowSymlinks
Order allow,deny
Allow from all
</Directory>
</IfModule>
# 配置虚拟主机
NameVirtualHost *
# tmitter app Config
<VirtualHost *:80>
ServerName www.tmitter.us
DocumentRoot D:/work/tmitter
AspNetMount / "D:/work/tmitter"
<Directory "D:/work/tmitter/www">
Options Indexes FollowSymLinks Includes ExecCGI
Order allow,deny
AllowOverride All
Allow from all
DirectoryIndex index.html default.aspx
</Directory>
</VirtualHost>
<VirtualHost *:80>
ServerName static.tmitter.us
DocumentRoot D:/work/tmitter/static
AspNetMount / "D:/work/tmitter/static"
<Directory "D:/work/tmitter/static">
Options FollowSymlinks ExecCGI
Options Indexes FollowSymLinks Includes ExecCGI
Order allow,deny
AllowOverride All
Allow from all
DirectoryIndex index.html default.aspx
</Directory>
</VirtualHost>
配置本地域名解析 hosts 文件
打开 c:\windows\system32\drivers\etc\hosts 这个文件，并加入
127.0.0.1 www.tmitter.us
127.0.0.1 static.tmitter.us
最后保存，这里名字和解析的细节跟据自已需求修改。
最后保存重启 Apache，重启过程会有些慢，估计是在编译 Asp.net 程序。完成后，打开 http://www.tmitter.us就可以看到效果了。
性能测试
我用的是公司的项目，这里面有使用 Memcached 做页面缓存的，但从 Url 请求到 Memcached 取数据中间还有一些逻辑，现在我开着缓存测试，结果是差距很明显。
