Puppet的server端与agent端的通讯创建

想让两台(或N台)机器相互通讯，先要设置它们之间的Host文件。
每一台机器分别执行以下命令sudo vi /etc/hosts把要相互通讯的全部机器的IP 和 别名添加进来。好比先以server端为例127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.23.10.237 puppet-server.noah.blogjava.net
#上面多是打开这个文件里默认的，不用管，直接在下面加agent的ip就能够了,有多少加多少。
10.52.27.71 agent001.noah-test.net
10.52.27.72 agent002.noah-test.net
10.52.27.73 agent003.noah-test.net
接下来把上面的都复制，而后，分别考到其它的机器里面。

接下来回到agent端，配置puppet 的配置文件，执行以下命令
sudo vi /etc/puppetlabs/puppet/puppet.conf在打开的文件里面填写以下信息
[main]
#这个certname就是上面host里面的名字
certname = agent001.noah-test.net
#server 就是puppet的server的地址
server = puppet-server.noah.blogjava.net
environment = production
runinterval = 1h

而后在agent端，执行以下命令，向server端申请证书
sudo /opt/puppetlabs/bin/puppet agent --test而后，会出现这样的信息
Info: Creating a new SSL key for agent01.noah-test
Info: Caching certificate for ca
Info: csr_attributes file loading from /etc/puppetlabs/puppet/csr_attributes.yaml
Exiting; no certificate found and waitforcert is disabled

证实，申请成功，等待server端赞成。这时能够转到server端，执行以下命令查看如些机器要申请证书sudo /opt/puppetlabs/bin/puppet cert list --all这里会显示出全部申请过的和正在等待审批的agent的certname 的名字。审批经过的前面有个“+”。
接下来执行以下命令进行单独审批
 sudo /opt/puppetlabs/bin/puppet cert sign agent001.noah-test.net

也能够直接在sgin 后面加 "--all",进行所有审批。

审批完成后，再回到agent端，执行一样的命令
sudo /opt/puppetlabs/bin/puppet agent --test
以下显示的全是相似以下绿色的信息，证实它们之间的通讯已经创建成功
Info: Using configured environment 'production'Info: Retrieving pluginfactsInfo: Retrieving pluginInfo: Caching catalog for agent001.noah-test.netInfo: Applying configuration version '1481877703'
