优点
*性能:nginx因为精简,运行起来非常快速,许多人声称它的比pound更高效。
*日志,调试:在这两个方面,nginx比pound更简洁。
*灵活性:nginx的处理SSL客户端验证是在应用层上实现的,而不会终止SSL连接。
*nginx可以拿来即用, 不需要像pound打补丁,同时配置的语法也很直观。
缺点
一但在服务端使用puppetca进行sgin以后,无法主动在服务端撤销授权,
不过你可以在客户端删除ssl目录来取消授权,一般情况下没什么影响。
配置步骤
配置yum
用光盘iso在本地建个yum软件仓库,并配置好epel源
mount rhel54.iso /mnt -o loop,ro
vim /etc/yum.repos.d/local.repo 写入以下配置
[Server]
name=Red Hat Enterprise Linux $releasever - $basearch - Server
baseurl=file:///mnt/Server
enabled=1
gpgcheck=0
[epel]
name=Red Hat Enterprise Linux $releasever - $basearch - epel
baseurl=http://mirrors.sohu.com/fedora-epel/5Server/$basearch
enabled=1
gpgcheck=0
配置Mongrel
安装puppet软件包
yum install puppetmaster puppet rubygem-mongrel
编辑 /etc/sysconfig/puppetmaster添加以下两行
PUPPETMASTER_PORTS=( 18140 18141 18142 18143 )
PUPPETMASTER_EXTRA_OPTS="—servertype=mongrel —ssl_client_header=HTTP_X_SSL_SUBJECT"
启动服务
service puppetmaster start
配置nginx
下面我们来配置nginx代替默认的webserver,我们可以用nginx来实现动静分离,
把静态的文件直接交给nginx来处理,比如files和modules模块中的files,
动态的再交给puppet,各扬所长,使其支持更多的节点
下载nginx-0.8.7或以上的源码包
wget http://nginx.org/download/nginx-0.8.47.tar.gz
tar zxf nginx-0.8.47.tar.gz
./configure —with-http_stub_status_module —with-http_ssl_module
make && make install
vim /usr/local/nginx/conf/nginx.conf 写入以下配置

worker_processes 4;
worker_rlimit_nofile 65535;
error_log /var/log/nginx-puppet.log notice;
