centos6.5(32位)  ruby可以直接安装（yum install ruby）

安装puppet的时候先要设定yum源：

rpm -Uvh http://yum.puppetlabs.com/el/5/products/i386/puppetlabs-release-5-7.noarch.rpm

yum clean all

yum install puppet-server(master端)

yum install puppet（agent端）

有时候会报错：

Error: Package: ruby-libs-1.8.7.374-2.el5.i386 (puppetlabs-deps)
           Requires: libtcl8.4.so
Error: Package: ruby-libs-1.8.7.374-2.el5.i386 (puppetlabs-deps)
           Requires: libtk8.4.so
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

 google之后，基本上都是是没有指定yum源，但是我开始就按照《pro puppet 2nd》和刘宇的《Puppet实战》指定了yum源，开始总是报错，后面敲上面命令却成功安装puppet,真是奇怪。
