RHEL 6.3下学习puppet(安装篇)

安装完RHEL 6.3 首要做的就是添加centos 6.3的软件源

1. 先把RHEL自带的yum卸载

rpm -e --nodeps yum-metadata-parser-1.1.2-16.el6.i686 yum-3.2.29-30.el6.noarch yum-rhn-plugin-0.9.1-40.el6.noarch

2. 安装centos的yum版本

curl -O mirrors.163.com/centos/6.3/os/i386/Packages/yum-3.2.29-30.el6.centos.noarch.rpm
curl -O http://mirrors.163.com/centos/6.3/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm
curl -O http://mirrors.163.com/centos/6.3/os/i386/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm
curl -O http://mirrors.163.com/centos/6.3/os/i386/Packages/yum-utils-1.1.30-14.el6.noarch.rpm

3. 添加centos 163源

[base]
name=CentOS-6.3 - Base - 163.com
baseurl=http://mirrors.163.com/centos/6.3/os/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=6.3&arch=$basearch&repo=os
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

#released updates 
[updates]

gpgcheck=1

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

4. 更新源

yum makecache

安装puppet，facter

环境说明：

puppet master ：

yum install ruby ruby-libs ruby-shadow ruby-rdoc
yum install puppet facter
#如果是puppet master 还需要安装
yum install puppet-server  #for redhat or centos
apt-get install puppetmaster # for ubuntu

默认puppet的配置文件在 /etc/puppet

在配置puppet之前，要做很重要的一件事就是设置好master和agent的主机名，并把puppet master的主机ip解析写入到hosts文件

10.217.12.115 puppet puppet.example.com #ip地址换成你的puppet master主机的ip

修改puppet master 的配置文件 puppet.conf

[master]
certname = puppet.example.com #添加这一行

修改puppet agent配置文件 puppet.conf

[main]
    server = puppet.example.com #添加这一行

master端启动puppet

puppet master --verbose --no-daemonize

agent端启动

agent发出证书等待master签名

puppet agent --verbose --no-daemonize

master端执行

puppet cert --list #查看等待前面的agent证书
puppet cent --sign --all #签名所有需要签名的证书

如果没有问题，大概2分钟agent端就有屏幕输出，表示已经收到master的签名证书
