192.168.154.138 agent1.localdomain #Puppet Agentshell
這裏的機器名稱不要有下劃線等特殊符合,不然後面會報「the scheme puppet does not accept registry part」這樣的錯誤信息。centos
centos的官方軟件庫裏面不包含puppet包,可是在epel項目裏面有包含puppet包。epel 是一個對rhel軟件倉庫的擴展,把一些有用的,可是rhel庫沒包含的軟件收集在一塊兒作成的一個軟件倉庫。緩存
$ yum install epel-release
$ hostnamectl set-hostname master.localdomain #設置機器名稱 $ systemctl reboot #重啓 $ cat /etc/hosts 192.168.154.137 master.localdomain 192.168.154.138 agent1.localdomain $ yum install puppet-server #安裝Puppet Server # firewall-cmd --permanent --add-port=8140/tcp6 #修改防火牆,增長8140端口
$ hostnamectl set-hostname agent1.localdomain #設置機器名稱 $ systemctl reboot #重啓 $ cat /etc/hosts 192.168.154.137 master.localdomain $ yum install puppet #安裝Puppet Agent
建立測試文件site.pp(Server端):bash
$ cat /etc/puppet/manifests/site.pp node default { file { "/tmp/helloworld.txt" : content => "Hello World!", } }
啓動server,以no-daemonize方式,這樣能夠在控制檯看到操做信息(Server端):less
$ puppet master --no-daemonize --debug ... ... Notice: Starting Puppet master version 3.6.2 #啓動成功,會看到這樣的信息
編輯客戶端puppet.conf,增長server配置項(Agent端):dom
$ cat /etc/puppet/puppet.conf [agent] ... ... server = master.localdomain
啓動agent(Agent端,以root用戶):tcp
$ puppet agent --test Info: Creating a new SSL key for agent1.localdomain Info: Caching certificate for ca Info: csr_attributes file loading from /etc/puppet/csr_attributes.yaml Info: Creating a new SSL certificate request for agent1.localdomain Info: Certificate Request fingerprint (SHA256): 1D:08:61:3B:1F:43:8C:B5:81:83:0F:FF:CC:4A:4F:8E:BA:B4:5F:7C:94:77:15:72:A2:0C:C0:44:D9:1D:16:9E Info: Caching certificate for ca Exiting; no certificate found and waitforcert is disabled
啓動後,agent向server申請證書,由於證書尚未被server審覈,因此目前通訊是不成功的。測試
回到server,經過puppet cert查詢證書:
$ puppet cert list --all "agent1.localdomain" (SHA256) 1D:08:61:3B:1F:43:8C:B5:81:83:0F:FF:CC:4A:4F:8E:BA:B4 + "master.localdomain" (SHA256) 47:A1:12:28:22:05:75:A5:E5:92:2B:F6:53:05:A8:D6:1F:9B
證書列表中有cs_agnet1的申請,目前是未審覈狀態(最前面沒有+)。審覈證書:
$ puppet cert sign agent1.localdomain $ puppet cert list --all + "agent1.localdomain" (SHA256) 39:7F:59:A8:3C:B8:EF:B9:E2:AD:1D:5C:D7:66:B6:02:CF:70 + "master.localdomain" (SHA256) 47:A1:12:28:22:05:75:A5:E5:92:2B:F6:53:05:A8:D6:1F:9B:
再次啓動agent:
# puppet agent --test Info: Retrieving pluginfacts Info: Retrieving plugin Info: Caching catalog for agent1.localdomain Info: Applying configuration version '1479087051' Notice: /Stage[main]/Main/Node[default]/File[/tmp/helloworld.txt]/ensure: defined content as '{md5}ed076287532e86365e841e92bfc50d8c' Notice: Finished catalog run in 0.02 seconds
這時候,查看/tmp/helloworld.txt,該文件就自動同步了。
在證書申請過程當中,若是有問題,能夠刪除證書從新申請,通常都能解決問題。
Agent: $ rm -rf /var/lib/puppet #刪除緩存文件 Server: $ puppet cert clean agent1.localdomain
在測試時,先啓動Server,再經過Agent測試,回到Server經過puppet cert list --all怎麼都找不到證書。
後來發現問題緣由是這樣的:在Server端,puppet.conf使用的是默認配置:
[main]
# Where SSL certificates are kept.
ssldir = $vardir/ssl
而後用admin賬號(不是root,另外建立的賬號)啓動Server:
[admin@master ~]$ sudo puppet master --no-daemonize --debug
這時候,Agent傳過來的證書申請實際上都存放在/home/admin/.puppet/ssl/目錄下。而後,我再開了另一個SSH Client,用的是不一樣的root賬號,結果就是怎麼也找不到證書了。因此,在配置Server端時,ssldir最好這樣配置:
ssldir = /var/lib/puppet/ssl
建立autosign.conf文件:
$ cat /etc/puppet/autosign.conf *.localdomain
修改Server配置:
$ cat /etc/puppet/puppet.conf [master] autosign = /etc/puppet/autosign.conf
刪除Server和Agent的過時證書:
Server: $ puppet cert clean --all Agent: $ rm -rf /var/lib/puppet
OK,這樣就能夠了。
$ cat /etc/puppet/manifests/site.pp node default { file { '/tmp/hello.txt': content => 'Hello World!', } user { 'admin': ensure => 'present', comment => 'admin', gid => '1000', groups => ['wheel', 'admin'], home => '/home/admin', password => '$6$o.PFkMC14Xd2gOTk$atsNGzVmLFtQlvVr9imERjmw9n8vNr0quliqW6EdcZR6zyXFGfUv3EIbc9UZd3kJDIuxuMfyonVdm0OT5SJHM.', password_max_age => '99999', password_min_age => '0', shell => '/bin/bash', uid => '1000', } package { 'epel-release': ensure => 'installed', } package { 'tcping': ensure => 'installed', } package { 'tree': ensure => 'installed', } package { 'net-tools': ensure => 'installed', } service { 'firewalld.service': ensure => 'stopped', enable => 'false', } exec { "selinux": command => "setenforce 0", path => "/usr/bin:/usr/sbin:/bin:/sbin", unless => "getenforce |grep -i Permissive", } }
