httpd+passenger处理puppet大并发

 

httpd+passenger处理puppet大并发

puppetmaster默认使用的是ruby自带的web服务器WEBRick，它太过简陋，无法满足puppet客户端成百上千的并发，apache成熟稳定、功能强大，这里用apache替换WEBRick。步骤如下

禁用selinux ，修改/etc/selinux/config

SELINUX=disabled

（必须果断禁用selinux，我测试好久没成功都怪它捣鬼。方法有很多，在grub内核启动参数后加selinux=0 也可）

 

用puppet的方式安装apache 和 mod_ssl (等效于yum install)

# puppet resource package httpd ensure=present
# puppet resource package mod_ssl ensure=present
# puppet resource service httpd ensure=stopped

 

安装passenger

passenger是一套apache的ruby模块，工作方式跟mod_php差不多

# rpm -Uvh  http://passenger.stealthymonkeys.com/rhel/6/passenger-release.noarch.rpm
# yum install mod_passenger --enablerepo=epel

 

1、httpd的配置文件 

# cp /usr/share/puppet/ext/rack/files/apache2.conf /etc/httpd/conf.d/rack.conf

很不幸，这里的配置文件是给debian/ubuntu用的，需要修正一些设置，譬如ssl路径为/var/lib/puppet/ssl

 

还有两行要注意，证书名字需要替换，否则httpd报错文件不存在，无法启动httpd。

 

 将

SSLCertificateFile  /etc/puppet/ssl/certs/squigley.namespace.at.pem
SSLCertificateKeyFile   /etc/puppet/ssl/private_keys/squigley.namespace.at.pem

替换成

SSLCertificateFile  /var/lib/puppet/ssl/certs/puppet.test.org.pem
SSLCertificateKeyFile   /var/lib/puppet/ssl/private_keys/puppet.test.org.pem

 

2、建立httpd虚拟主机的根目录，/etc/puppet/rack  

# mkdir -p /etc/puppet/rack/{public,tmp}
# cp /usr/share/puppet/ext/rack/files/config.ru /etc/puppet/rack/
# chown puppet:puppet /etc/puppet/rack/config.ru

 (config.ru 文件为触发apache调用puppetmaster )

3、测试成功

# chkconfig puppetmaster off
# chkconfig httpd on
# service httpd start
# puppet agent --test
info: Caching catalog for apache01.test.org
info: Applying configuration version '1343463477'
notice: Finished catalog run in 0.02 seconds

 （补充说明，8140端口被apache占据，因此puppetmaster应该禁用。 ）
