Fedora5中安装Nginx
注意：该文只能供参考在fedota安装Nginx时遇到的问题，如果版本是fedora5并且全部按照本文的做法，可能会
导致操作系统出现问题。
在Fedora5中安装Nginx，绝对是件痛苦的事情，下面是痛苦的过程：
为了解决"Cannot find a valid baseurl for repo: core"问题，修改yum软件源：
对于Fedora，首先修改yum的软件源，使用速度比较快的国内镜像。按照以下修改/etc/yum.repos.d目录的下面fedora-core.repo,fedora-extras.repo和fedora-updates.repo这几个文件：
#/etc/yum.repos.d/fedora-core.repo
[core]
name=Fedora Core $releasever - $basearch - Base
#baseurl=http://download.fedora.redhat.com/pub/fedora/linux/core/$releasever/$basearch/os/
baseurl=ftp://ftp3.tsinghua.edu.cn/mirror/fedora/updates/10/i386/
#baseurl=http://mirrors.geekbone.org/fedora/core/$releasever/$basearch/os/
#mirrorlist=http://fedora.redhat.com/download/mirrors/fedora-core-$releasever
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora file:///etc/pki/rpm-gpg/RPM-GPG-KEY#/etc/yum.repos.d/fedora-extras.repo#/etc/yum.repos.d/fedora-updates.repo
[extras]
name=Fedora Extras $releasever - $basearch
#baseurl=http://download.fedora.redhat.com/pub/fedora/linux/extras/$releasever/$basearch/
baseurl=ftp://ftp3.tsinghua.edu.cn/mirror/fedora/updates/10/i386/
#baseurl=http://mirrors.geekbone.org/fedora/extras/$releasever/$basearch/
#mirrorlist=http://fedora.redhat.com/download/mirrors/fedora-extras-$releasever
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-extras
gpgcheck=1
[updates]
name=Fedora Core $releasever - $basearch - Released Updates
#baseurl=http://download.fedora.redhat.com/pub/fedora/linux/core/updates/$releasever/$basearch/
baseurl=ftp://ftp3.tsinghua.edu.cn/mirror/fedora/updates/10/i386/
#baseurl=http://mirrors.geekbone.org/fedora/core/updates/$releasever/$basearch/
#mirrorlist=http://fedora.redhat.com/download/mirrors/updates-released-fc$releasever
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora
为了解决问题"g++: command not found"，安装gcc-c++：
出现该情况是由于c++编译器的相关package没有安装，以root用户登陆，在终端上执行：
# yum install glibc-headers
# yum install gcc-c++
为了确保能在 Nginx 中使用正则表达式进行更灵活的配置，安装之前需要确定系统是否安装有 PCRE（Perl Compatible Regular Expressions）包。您可以到 ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/ 下载最新的 PCRE 源码包，使用下面命令下载编译和安装 PCRE 包：
# wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-7.7.tar.gz |
为了能使Nginx编译通过，解决"zlib.h 没有那个文件"问题，升级zlib，zlib-devel。
#Update the package deciding which yum repositories to use,Switch repositories:
rpm -Uhv http://mirror.liberty.edu/pub/fedora/linux/releases/10/Fedora/i386/os/Packages/fedora-release-10-1.noarch.rpm http://mirror.liberty.edu/pub/fedora/linux/releases/10/Fedora/i386/os/Packages/fedora-release-notes-10.0.0-1.noarch.rpm
yum install zlib-devel
yum install zlib
接下来安装 Nginx，Nginx 一般有两个版本，分别是稳定版和开发版，您可以根据您的目的来选择这两个版本的其中一个，下面是把 Nginx 安装到 /opt/nginx 目录下的详细步骤：
# wget http://sysoev.ru/nginx/nginx-0.6.36.tar.gz |
其中参数 --with-http_stub_status_module 是为了启用 nginx 的 NginxStatus 功能，用来监控 Nginx 的当前状态。

Tapestry5用Redirect-After-Post模式保证刷新和后退的安全
Redirect-after-post
Once Tapestry knows which page is next, why doesn't Tapestry just render it and return it? Because Tapestry uses the Redirect-After-Post pattern: it constructs a render request URL to the next page, just like PageLink does, and returns that URL to the browser as a redirect. So when the next page shows, its URL will not be the URL that submitted the form. Its URL will be safe to bookmark, reload or return to. The cost is 2 trips to the server, but it's worth it.

通过Java访问需用户密码和Windows域认证的代理
Java通过代理访问网络设置，代理服务器需要用户/密码和Windows域验证：
System.setProperty( "proxySet", "true" );
System.setProperty( "http.proxyHost", "localhost" );
System.setProperty( "http.proxyPort", "8080" );
System.setProperty( "http.auth.ntlm.domain", "searchfull.net" );
Authenticator.setDefault(new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("username",
new String("password").toCharArray());
}
});
System.setProperty( "proxySet", "true" );
System.setProperty( "http.proxyHost", "localhost" );
System.setProperty( "http.proxyPort", "8080" );
System.setProperty( "http.auth.ntlm.domain", "searchfull.net" );
Authenticator.setDefault(new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("username",
new String("password").toCharArray());
}
});
