1，遵循前面的环境设定，我们这里的服务器环境及软件版本分别为:
服务器系统：centos5.8 x86_64
Ruby版本：ruby-1.8.5
Puppet版本：puppet-2.7.9
nginx版本：nginx-0.8.46
2，Mongrel安装
要使用puppet多端口配置，需要指定mongrel类型，默认没有安装，需要安装：
3，配置puppetmaster
在/etc/sysconfig/puppetmaster文件末尾添加如下两行，分别代表多端口、mongrel类型，内容如下所示：
4，安装Nginx服务
安装之前请确保系统已经安装pcre-devel正则库，然后再编译安装Nginx，需要添加SSL模块参数支持，Nginx的安装过程如下所示：
添加www用户组及用户，命令如下所示：
5，我们依据puppet需求来修改配置文件nginx.conf，内容如下所示：
user www;
worker_processes 8;
events {
worker_connections 65535;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
tcp_nopush on;
keepalive_timeout 65;
#定义puppet客户端访问puppet-server端日志格式
log_format main '$remote_addr - $remote_user [$time_local] "$request" $request_length $request_time $time_local'
'$status $body_bytes_sent $bytes_sent $connection $msec "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for $upstream_response_time $upstream_addr $upstream_status ';
access_log /usr/local/nginx/logs/access.log main;
upstream puppetmaster {
server 127.0.0.1:8141;
server 127.0.0.1:8142;
server 127.0.0.1:8143;
server 127.0.0.1:8144;
server 127.0.0.1:8145;
}
server {
listen 8140;
root /etc/puppet;
ssl on;
ssl_session_timeout 5m;
#如下为puppetmaster服务器端证书地址
ssl_certificate /var/lib/puppet/ssl/certs/server.cn7788.com.pem;
ssl_certificate_key /var/lib/puppet/ssl/private_keys/server.cn7788.com.pem;
ssl_client_certificate /var/lib/puppet/ssl/ca/ca_crt.pem;
ssl_crl /var/lib/puppet/ssl/ca/ca_crl.pem;
ssl_verify_client optional;
#File sections
location /production/file_content/files/ {
types { }
default_type application/x-raw;
#定义puppet推送路径别名
alias /etc/puppet/files/;
}
# Modules files sections
location ~ /production/file_content/modules/.+/ {
root /etc/puppet/modules;
types { }
default_type application/x-raw;
rewrite ^/production/file_content/modules/(.+)/(.+)$ /$1/files/$2 break;
}
location / {
##设置跳转到puppetmaster负载均衡
proxy_pass http://puppetmaster;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Client-Verify $ssl_client_verify;
proxy_set_header X-SSL-Subject $ssl_client_s_dn;
proxy_set_header X-SSL-Issuer $ssl_client_i_dn;
proxy_buffer_size 10m;
proxy_buffers 1024 10m;
proxy_busy_buffers_size 10m;
proxy_temp_file_write_size 10m;
proxy_read_timeout 120;
}
}
}
6，修改完nginx.conf文件以后，要启动nginx及puppet-server，这时应该如何操作呢？
1.首先关闭puppetmaster进程，然后先启动nginx，不然nginx是会启动失败的，命令如下所示：
nginx占用puppetmaster默认的8140端口后，我们可以用如下命令来检查8140端口是否被nginx接管，如下所示：
lsof -i:8140
此命令显示结果表明8140被nginx进程接管，如下所示：
再启动puppetmaster，命令如下所示：
service puppetmaster start
如果ruby版本为1.8.5的话，等会运行puppetmaster会有如下警告，如下所示：
这段警告值的意思为：
It's just a warning. Mongrel wants a Ruby version of at least 1.8.6.
But it still runs just fine with previous versions. Just ignore the warning.
中文意思：
Mongrel需要ruby至少是1.8.6以上的版本，但它仍然在当前版本运行，请忽略当前警告，为保证整个puppet运行环境的稳定，这里选择沿用1.8.5版本的ruby。
