零基础学习Puppet自动化配置管理系列文档
描述：puppet使用SSL(https)协议来进行通讯，默认情况下，puppet server端使用基于Ruby的WEBRick HTTP服务器。由于WEBRick HTTP服务器在处理agent端的性能方面并不是很强劲，因此需要扩展puppet，搭建nginx或者其他强劲的web服务器来处理客户的https请求。
需要解决的问题：
Nginx+Passenger方式：
1、安装编译nginx所需要的开发包
[root@TKPUPT-M1 ~]# groupadd -g 3001 nginx [root@TKPUPT-M1 ~]# useradd -u 3001 -g 3001 nginx [root@TKPUPT-M1 ~]# yum install ruby-devel gcc make pcre-devel zlib-devel openssl-devel pam-devel curl-devel rpm-build
2、安装passenger（将gem软件包copy到本地）
备注：需要先将gem包下载到本地，当然也可以联网安装，会非常慢。
[root@TKPUPT-M1 gem]# gem install --localhost rake rack passenger --no-rdoc --no-ri
3、解压nginx、pcre源码包
[root@TKPUPT-M1 gem]# tar xf pcre-8.32.tar.gz -C /usr/local/src/ [root@TKPUPT-M1 gem]# tar xf nginx-1.4.2.tar.gz -C /usr/local/src/
4、编译并安装nginx
备注：主要是为了将模块passenger-config编译进来。
[root@TKPUPT-M1 ~]# cd /usr/local/src/nginx-1.4.2/ [root@TKPUPT-M1 nginx-1.4.2]# ./configure --user=nginx --group=nginx --prefix=/etc/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.32 --add-module=`passenger-config --root`/ext/nginx [root@TKPUPT-M1 nginx-1.4.2]# make && make install
5、与passenger结合
备注：注意config.ru的属主和属组应该为puppet
[root@TKPUPT-M1 nginx-1.4.2]# mkdir -p /etc/puppet/rack/public [root@TKPUPT-M1 nginx-1.4.2]# cp /usr/share/puppet/ext/rack/config.ru /etc/puppet/rack/ [root@TKPUPT-M1 nginx-1.4.2]# chown -R puppet. /etc/puppet/rack/
6、复制启动脚本到
[root@TKPUPT-M1 init.d]# cp /root/gem/nginx /etc/init.d/ [root@TKPUPT-M1 ~]# chmod a+x /etc/init.d/nginx
7、配置nginx
备注：注意和puppet结合的证书名称及路径
[root@TKPUPT-M1 gem]# vim /etc/nginx/conf/nginx.conf
user nginx nginx;
worker_processes 1;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
passenger_root /usr/lib/ruby/gems/1.8/gems/passenger-4.0.19;
passenger_ruby /usr/bin/ruby;
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 8140 ssl;
server_name puppetmaster;
passenger_enabled on;
passenger_set_cgi_param HTTP_X_CLIENT_DN $ssl_client_s_dn;
passenger_set_cgi_param HTTP_X_CLIENT_VERIFY $ssl_client_verify;
proxy_buffer_size 4000k;
proxy_buffering on;
proxy_buffers 32 1280k;
proxy_busy_buffers_size 17680k;
client_max_body_size 10m;
client_body_buffer_size 4096k;
access_log /var/log/nginx/puppet_access.log;
error_log /var/log/nginx/puppet_error.log;
root /etc/puppet/rack/public;
ssl off;
ssl_session_timeout 5m;
ssl_certificate /var/lib/puppet/ssl/certs/puppetmaster.pem;
ssl_certificate_key /var/lib/puppet/ssl/private_keys/puppetmaster.pem;
ssl_client_certificate /var/lib/puppet/ssl/certs/ca.pem;
ssl_crl /var/lib/puppet/ssl/ca/ca_crl.pem;
ssl_verify_client optional;
ssl_ciphers SSLv2:-LOW:-EXPORT:RC4+RSA;
ssl_prefer_server_ciphers on;
ssl_verify_depth 1;
ssl_session_cache shared:SSL:128m;
# File sections
location /production/file_content/files/ {
types { }
default_type application/x-raw;
alias /etc/puppet/files/;
}
}
}
8、配置puppet.conf
[root@TKPUPT-M1 ~]# vim /etc/puppet/puppet.conf [master] certname = puppetmaster ca = false ssl_client_verify_header = HTTP_X_CLIENT_VERIFY ssl_client_header = HTTP_X_CLIENT_DN
8、启动nginx
[root@TKPUPT-M1 gem]# mkdir /var/log/nginx/ [root@TKPUPT-M1 nginx-1.4.2]# /etc/init.d/puppetmaster stop [root@TKPUPT-M1 nginx-1.4.2]# chkconfig puppetmaster off [root@TKPUPT-M1 nginx-1.4.2]# /etc/init.d/nginx start [root@TKPUPT-M1 nginx-1.4.2]# chkconfig nginx on
9、测试
在多个节点发起puppet agent -t命令动作，查看nginx日志看nginx+passenger是否代理成功。
[root@TKPUPT-CA ~]# puppet agent -t [root@TKPUPT-M1 ~]# tailf /var/log/nginx/puppet_access.log
