puppet自動部署安裝VSFTP後，客戶端需要拉取兩次才能安裝、啓動服務

Q: puppet自動部署安裝VSFTP後，客戶端需要拉取兩次才能安裝、啓動服務

[root@agent1 mnt]# puppet agent -t
Info: Retrieving pluginfacts
Info: Retrieving plugin
Info: Caching catalog for agent1.yu.net
Info: Applying configuration version '1525403897'
Error: Could not start Service[vsftpd]: Execution of '/sbin/service vsftpd start' returned 1: vsftpd: unrecognized service
Error: /Stage[main]/Vsftpd/Service[vsftpd]/ensure: change from stopped to running failed: Could not start Service[vsftpd]: Execution of '/sbin/service vsftpd start' returned 1: vsftpd: unrecognized service
Notice: /Stage[main]/Vsftpd/Package[vsftpd]/ensure: created
Notice: Finished catalog run in 8.40 seconds

A:

1.第一次拉取資源顯示上面錯誤。自己service啓動成功。

    [root@agent1 mnt]# service vsftpd start
    Starting vsftpd for vsftpd:                                [  OK  ]

2.將vsftpd卸載，重新用puppet安裝

    [root@agent1 mnt]# rpm -e vsftpd
    [root@agent1 mnt]# service vsftpd status
    vsftpd: unrecognized service
    //卸載成功

3.重新使用puppet安裝、啓動。

    [root@agent1 mnt]# puppet agent -t
    Info: Retrieving pluginfacts
    Info: Retrieving plugin
    Info: Caching catalog for agent1.yu.net
    Info: Applying configuration version '1525403897'
    Error: Could not start Service[vsftpd]: Execution of '/sbin/service vsftpd start' returned 1: vsftpd: unrecognized service
    Error: /Stage[main]/Vsftpd/Service[vsftpd]/ensure: change from stopped to running failed: Could not start Service[vsftpd]: Execution of '/sbin/service vsftpd start' returned 1: vsftpd: unrecognized service
    Notice: /Stage[main]/Vsftpd/Package[vsftpd]/ensure: created
    Notice: Finished catalog run in 6.12 seconds

再次出錯！

4.再次使用puppet

[root@agent1 mnt]# puppet agent -t
Info: Retrieving pluginfacts
Info: Retrieving plugin
Info: Caching catalog for agent1.yu.net
Info: Applying configuration version '1525403897'
Notice: /Stage[main]/Vsftpd/Service[vsftpd]/ensure: ensure changed 'stopped' to 'running'
Info: /Stage[main]/Vsftpd/Service[vsftpd]: Unscheduling refresh on Service[vsftpd]
Notice: Finished catalog run in 0.35 seconds
[root@agent1 mnt]# service vsftpd status
vsftpd (pid 26895) is running...

成功啓動！

總結：爲何無法一次成功？需要puppet拉去兩次？

5.嘗試更改執行服務方式，改爲執行命令

  1 class vsftpd{
  2         yumrepo {"Server":
  3         descr => "Server repo",
  4         baseurl => "file:///mnt/dvd",
  5         gpgcheck=>"0",
  6         enabled =>"1";
  7 
  8 }
  9 
 10         package {"vsftpd":
 11         ensure=>installed,
 12         require=>Yumrepo["Server"];
 13 }
 14 
 15 
 16         exec  {"vsftpd":                        
 17         command=>'/etc/init.d/vsftpd start',
 18         owner =>'root',
 19         path=>["/bin/sbin/vsftpd"];
 20 }


或者
exec  {"/etc/init.d/vsftpd start":
          owner =>'root'；
          }


//以上命令執行語法格式有問題，正確格式如下：
exec{'vsftpd':
        path =>'/bin:/sbin:/usr/bin:/usr/sbin',
        command => '/etc/init.d/vsftpd start',
    }

並不好使！報錯

[root@agent2 ~]# puppet agent -t
Info: Retrieving pluginfacts
Info: Retrieving plugin
Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Invalid parameter owner on Exec[vsftpd] at /etc/puppet/modules/vsftpd/manifests/init.pp:20 on node agent2.yu.net
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run

6.更改服務執行位置到vim /etc/puppet/manifests/site.pp

 1 node 'default' {
  2         include vsftpd
  3 
  4         service {"vsftpd":
  5         ensure => running;
  6   }

 10 }

 報錯：
[root@agent2 ~]# puppet agent -t
Info: Retrieving pluginfacts
Info: Retrieving plugin
Info: Caching catalog for agent2.yu.net
Info: Applying configuration version '1525659052'
Error: Could not start Service[vsftpd]: Execution of '/sbin/service vsftpd start' returned 1: vsftpd: unrecognized service
Error: /Stage[main]/Main/Node[default]/Service[vsftpd]/ensure: change from stopped to running failed: Could not start Service[vsftpd]: Execution of '/sbin/service vsftpd start' returned 1: vsftpd: unrecognized service
Notice: /Stage[main]/Vsftpd/Package[vsftpd]/ensure: created
Notice: Finished catalog run in 11.69 seconds
[root@agent2 ~]# 

和之前一樣的錯誤！

7.改爲執行命令

  1 node 'default' {
  2         include vsftpd
  3 
  4 exec  {"/etc/init.d/vsftpd start":
  5         owner =>'root';
  6 }
  7 
  8 }
~          

還是報錯！
[root@agent2 ~]# puppet agent -t
Info: Retrieving pluginfacts
Info: Retrieving plugin
Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Invalid parameter owner on Exec[/etc/init.d/vsftpd start] at /etc/puppet/manifests/site.pp:6 on node agent2.yu.net
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run

8.經查找資料發現是依賴關係問題，puppet中的多個命令並不會按順序依次執行，可能會跳躍執行，所以啓動服務命令在安裝命令之前執行了，造成了錯誤，第二次拉取時，因爲已經安裝了，跳過安裝步驟，直接執行，所以就成功了。如果想解決問題，應當在服務之間加上依賴：

 18         package {"vsftpd":
 19                 ensure=>present,
 20                 name =>vsftpd,
 21 
 22         }->                             //次序連；作用和require/before類似
 23         service {"vsftpd":
 24                 ensure =>running,
 25                 name =>vsftpd,
 26                 require=>Package['vsftpd'],   //本模塊需要在package['vsftpd']模塊之後執行
 27         }

成功解決！
