如何在Ubuntu 16.04上安装和配置Puppet 4
慕飞章
本文向大家介绍如何在Ubuntu 16.04上安装和配置Puppet 4，包括了如何在Ubuntu 16.04上安装和配置Puppet 4的使用技巧和注意事项，需要的朋友参考一下
在本文中，我们将学习–如何在Ubuntu 16.04上安装和配置Puppet 4。Puppet是一种配置管理工具，可帮助系统管理员自动化任务。这些类型的工具也将节省大量时间和精力。
先决条件
在本文的此处，我们至少需要两到三台具有以下要求的Ubuntu计算机。
所有具有非root用户且对计算机具有Sudo权限的计算机。
一位木偶大师
一两个木偶代理来测试配置。
配置主机文件
与主机名进行通信所需的所有服务器和客户端，通常，这将由DNS服务器完成。在本演示中，我们没有任何DNS服务器，因此我们需要手动将主机名添加到/ etc / hosts文件中。
需要使用以下文本添加所有/ etc / hosts文件
$sudo vi /etc/hosts 192.168.0.1 puppet 192.168.0.200 ubuntu1
默认情况下，人偶主控被称为人偶，这使设置人偶变得容易。这意味着，我们需要如以下示例192.168.0.1所示分配Puppet服务器，如果我们未在Puppet主服务器中指定值，则puppet客户端将无法与服务器通信。
安装和配置Puppet服务器
默认情况下，Ubuntu软件包管理器不提供puppet软件包，因为我们将从Puppet官方存储库下载并安装它。以下是用于将the存储库安装并添加到服务器计算机的命令。
以下是用于将人偶存储库安装并添加到服务器计算机的命令–
puppet$ sudo curl -O https://apt.puppetlabs.com/puppetlabs-release-pc1-xenial.deb % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 13662 100 13662 0 0 7787 0 0:00:01 0:00:01 --:--:-- 7784 puppet$ sudo dpkg -i puppetlabs-release-pc1-xenial.deb Selecting previously unselected package puppetlabs-release-pc1.

更新完成后，我们需要运行以下命令在本地人偶服务器上安装人偶。

为Puppet服务器启用防火墙
安装完成后，我们需要默认情况下为人偶打开防火墙，人偶的默认端口为8140，以下是用于为人偶服务器打开防火墙(UFW)的命令，以允许来自客户端的传入连接。
ubuntu@puppet:~$ sudo ufw allow 8140 Rules updated Rules updated (v6)
自定义Puppet服务器和节点的内存分配
默认情况下，会将2 GB内存分配给Puppet主服务器，我们可以根据Puppet服务器的内存进行自定义。
我们需要编辑下面的文件“ / etc / default / puppet server”，我们需要找到下面的行并进行相应的编辑`JAVA_ARGS =”-Xms2g -Xmx2g -XX：MaxPermSize = 256m”`，这里我使用的是4 GB内存
ubuntu@puppet$ sudo nano /etc/default/puppetserver ########################################### # Init settings for puppetserver ########################################### # Location of your Java binary (version 7 or higher) JAVA_BIN="/usr/bin/java" # Modify this if you'd like to change the memory allocation, enable JMX, etc JAVA_ARGS="-Xms4g –Xmx4g -XX:MaxPermSize=256m" # These normally shouldn't need to be edited if using OS packages USER="puppet" GROUP="puppet" INSTALL_DIR="/opt/puppetlabs/server/apps/puppetserver" CONFIG="/etc/puppetlabs/puppetserver/conf.d" # Bootstrap path BOOTSTRAP_CONFIG="/etc/puppetlabs/puppetserver/services.d/,/opt/puppetlabs/server/apps/puppetserver/config/services.d/" # SERVICE_STOP_RETRIES can be set here to alter the default stop timeout in # seconds. For systemd, the shorter of this setting or 'TimeoutStopSec' in # the systemd.service definition will effectively be the timeout which is used. SERVICE_STOP_RETRIES=60 … …
完成配置后，我们需要启动Puppet Master，并将检查Puppet Master的状态。
ubuntu@puppet:~$ sudo systemctl start puppetserver ubuntu@puppet:~$ sudo systemctl status puppetserver puppet server.service - puppet server Service Loaded: loaded (/lib/systemd/system/puppetserver.service; disabled; vendor preset: enabled) Active: active (running) since Mon 2017-02-13 13:19:02 IST; 3s ago Process: 4943 ExecStart=/opt/puppetlabs/server/apps/puppetserver/bin/puppetserver start (code=exited, status=0/SUCCESS) Main PID: 4954 (java) Tasks: 26 Memory: 983.1M CPU: 50.819s CGroup: /system.slice/puppetserver.service └─4954 /usr/bin/java -Xms2g -Xmx2g -XX:MaxPermSize=256m -Djava.security.egd=/dev/urandom -XX:OnOutOfMemoryError=k Feb 13 13:18:10 puppet systemd[1]: Starting puppetserver Service...

在人偶节点上安装代理
我们需要为所有客户端安装代理，为此，我们需要添加Official Puppet存储库，然后在客户端上安装代理。

添加存储库后，我们需要运行以下命令来安装代理

安装成功后，我们需要启动代理并在启动时启用它。
ubuntu@ubuntu1:~$ sudo systemctl start puppet ubuntu@ubuntu1:~$ sudo systemctl enable puppet
在Puppet Master上对代理节点签名证书
当我们第一次运行代理节点时，该节点会将签名请求发送到Puppet主服务器，在该节点与Puppet主服务器之间发生任何通信之前，将在Puppet主服务器上创建证书签名请求
要使用Puppet主服务器查看当前的证书请求列表，请运行bellow命令
root@puppet:~# sudo /opt/puppetlabs/bin/puppet cert list "ubuntu1" (SHA256) 60:4C:AE:CE:BD:3F:EC:2F:C6:70:F6:45:62:EC:9A:AF:B2:8B:1C:42:4A:67:BB:C5:F6:F4:AE:BF:38:87:EA:9E
签署请求
要签署请求，请对特定节点运行以下命令。
$ sudo /opt/puppetlabs/bin/puppet cert sign ubuntu1 Signing Certificate Request for: "ubuntu1" (SHA256) 60:4C:AE:CE:BD:3F:EC:2F:C6:70:F6:45:62:EC:9A:AF:B2:8B:1C:42:4A:67:BB:C5:F6:F4:AE:BF:38:87:EA:9E Notice: Signed certificate request for ubuntu1 Notice: Removing file Puppet::SSL::CertificateRequest ubuntu1 at '/etc/puppetlabs/puppet/ssl/ca/requests/ubuntu1.pem'
要对请求进行签名，一次对所有节点运行以下命令
$ sudo /opt/puppetlabs/bin/puppet cert sign –all
创建和执行演示列表
演示示例列表
# vi /etc/puppetlabs/code/environments/production/manifests/site.pp
file {'/tmp/example-ip': # resource type file and filename
ensure => present, # make sure it exists
mode => '0644', # file permissions
content => "The Node IP address is ${ipaddress_eth0}!\n", # note the ipaddress_eth0 fact
}
这将显示/ tmp文件夹中的IP地址，列表将确保/ tmp文件夹中的所有节点都具有example-IP文件。
从客户端执行列表
以下是运行我们在服务器上创建的演示列表的命令
root@ubuntu1:~# sudo /opt/puppetlabs/bin/puppet agent --test
Info: Using configured environment 'production'
Info: Retrieving pluginfacts
Info: Retrieving plugin
Info: Caching catalog for ubuntu1

在上面的教程中，我们了解了–如何安装和配置Puppet Master和Puppet节点，以及如何为这些节点添加Sign in证书。此外，我们还创建了一个演示以从节点列表并执行以获取结果。
