Puppet 代理到 Puppet Master(在 nginx/ruby1.9 上运行)SSL 证书问题

Puppet 代理到 Puppet Master(在 nginx/ruby1.9 上运行)SSL 证书问题

我有两台机器,puppet master--主机名puppet--和一个单独的客户端,主机名git。主机上的 puppet 代理工作正常。代理git失败,并显示“400 未发送所需的 SSL 证书”。首先,puppet master 的配置是 thin/nginx 事务:

puppet:~# ruby -v
ruby 1.9.2p0 (2010-08-18 revision 29036) [i486-linux]

puppet:~# puppet --version
2.7.9

puppet:~# cat /etc/nginx/sites-enabled/default 
server {
  listen puppet:8140;

  ssl on;
  ssl_certificate /var/lib/puppet/ssl/certs/puppet.pem;
  ssl_certificate_key /var/lib/puppet/ssl/private_keys/puppet.pem;
  ssl_ciphers ALL:-ADH:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP;
  ssl_client_certificate  /var/lib/puppet/ssl/ca/ca_crt.pem;
  ssl_verify_client on;

  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-Client-Verify  SUCCESS;
  proxy_set_header X-Client-DN      $ssl_client_s_dn;
  proxy_set_header X-SSL-Subject    $ssl_client_s_dn;
  proxy_set_header X-SSL-Issuer     $ssl_client_i_dn;

  default_type application/x-raw;

  location /production/file_content/ {
    rewrite ^/production/file_content/modules/([^/]+)/(.*) /$1/files/$2;
    break;
    root /etc/puppet/modules/;
  }
  location / {
    proxy_pass http://puppet-production;
  }
}


# cat /etc/nginx/conf.d/puppet-production-upstream.conf 
upstream puppet-production {  
  server unix:/var/run/puppet/master.00.sock;
  server unix:/var/run/puppet/master.01.sock;
  server unix:/var/run/puppet/master.02.sock;
}


puppet:~# cat /etc/supervisor/conf.d/puppetmaster.conf 
# This file is autogenerated by Puppet. Manual changes will be overwritten!
[program:puppetmaster]
command=/usr/bin/thin start -e development --socket /var/run/puppet/master.%(process_num)02d.sock --user puppet --group puppet --chdir /etc/puppet -R /etc/puppet/config.ru
process_name=%(program_name)s_%(process_num)02d
numprocs=3
priority=999
autostart=true
autorestart=unexpected
startsecs=3
startretries=3
exitcodes=0,2
stopsignal=TERM
stopwaitsecs=10
redirect_stderr=false
stdout_logfile=/var/log/supervisor/puppetmaster/puppetmaster.out
stdout_logfile_maxbytes=250MB
stdout_logfile_backups=10
stderr_logfile=/var/log/supervisor/puppetmaster/puppetmaster.err
stderr_logfile_maxbytes=250MB
stderr_logfile_backups=10

puppet:~# cat /etc/puppet/puppet.conf 
[main]
ssldir=$vardir/ssl

[master]
certname=puppet

应用解决方法这里git当我尝试git向傀儡大师介绍时,我只能让代理到达这一点:

git:~# puppet agent --waitforcert 30 --test
err: Could not request certificate: Error 400 on SERVER: <html>
<head><title>400 No required SSL certificate was sent</title></head>
<body bgcolor="white">
<center><h1>400 Bad Request</h1></center>
<center>No required SSL certificate was sent</center>
<hr><center>nginx/1.1.8</center>
</body>
</html>

资源建议模拟 SSL 连接git从我的盒子中运行部分:

openssl s_client -host puppet -port 8140 -cert /var/lib/puppet/ssl/certs/git.troutwine.us.pem -key /var/lib/puppet/ssl/private_keys/git.troutwine.us.pem -CAfile /var/lib/puppet/ssl/certs/ca.pem

问题是我遗漏了/var/lib/puppet/ssl/certs/git.troutwine.us.pem

git:~# tree /var/lib/puppet/ssl/
/var/lib/puppet/ssl/
├── certificate_requests
├── certs
│   └── ca.pem
├── private
├── private_keys
│   └── git.troutwine.us.pem
└── public_keys
    └── git.troutwine.us.pem

普通的 webrick puppetmasterd 运行良好——只有 nginx/puppet 组合让我失望。两台机器都运行 ntpd,时间分布可以接受。我做错了什么?

答案1

频道中的 newl#puppet建议将其修改ssl_verify_client为“可选”,而不是“启用”。我已经这样做了,现在一切都很顺利。

我自己也确信这是一件坏事,但在 newl 的建议之后,我记不起为什么了。如果有人相信这是一个不太理想的配置设置,请告诉我。

如果您在主服务器上运行 Puppet 代理,则应确保它们不共享 SSL 目录。我曾见过该配置导致的奇怪结果。

摘自我的/etc/puppet/puppet.conf

[main]
# Where SSL certificates are kept for the puppet master and other
# subcommands.
# Note that this is a global setting because most of the subcommands
# other than 'agent' are only valid in puppetmaster context.
# The default value is '$confdir/ssl'.
vardir = /var/lib/puppetmaster
ssldir = $vardir/ssl

[agent]
# The var & SSL dir for the agent; listed explicitly because the master
# and other subcommands intended for the master should use
# the different SSL state.
# The default value is '$confdir/ssl'.
vardir = /var/lib/puppet
ssldir = $vardir/ssl
