saltstack學習一：安裝與升級

weixin_33858249發表於2017-11-12

由於我的伺服器是centos5，安裝後還要把zeromq升級，有點蛋疼


一：服務端的安裝：

1
2
3
4
rpm -Uvh http://mirror.pnl.gov/epel/5/i386/epel-release-5-4.noarch.rpm
yum install salt-master
chkconfig salt-master on
service salt-master start


二、客戶端的安裝：

1
2
3
4
5
6
7
rpm -Uvh http://mirror.pnl.gov/epel/5/i386/epel-release-5-4.noarch.rpm
yum install salt-minion
chkconfig salt-minion on
#修改/etc/salt/minion配置：
master: 192.168.1.100   #服務端IP
id: 192.168.1.101       #標識，我用本機IP做標識
service salt-minion start


起始以為就這樣快樂的安裝完了，但測試過程中發現minion端會產生一個殭屍程式，問了群上的大神綠肥才知道這是一個BUG，要把minion端升級到2014.1.1版本：

1
2
yum --enablerepo=epel-testing install salt-minion
service salt-minion restart

這樣殭屍程式的BUG總算解決了，後來網上一看原來centos5安裝salt還有一個BUG，就是zeromq的版本太低，還需要升級一下，於是又找到這個辦法來升級：

1
2
3
4
wget -O /etc/yum.repos.d/ownsource.repo http://www.comingchina.com:8080/testing/ownsource/ownsource.repo
yum clean all
yum update zeromq libzmq3 python26-zmq
service salt-minion restart

檢查一下版本：

1
2
3
4
5
6
7
8
9
10
11
[root@localhost Server]# salt-minion  --versions-report
           Salt: 2014.1.1
         Python: 2.6.8 (unknown, Nov  7 2012, 14:47:45)
         Jinja2: unknown
       M2Crypto: 0.21.1
 msgpack-python: 0.1.12
   msgpack-pure: Not Installed
       pycrypto: 2.3
         PyYAML: 3.08
          PyZMQ: 13.1.0
            ZMQ: 3.2.2

確實是升級成功了，於是後面就想用salt的state功能來完成剩下機器的升級，可是不會弄呀，果斷網上抄一份配置：

getownsourcerepo:
    cmd.run:
        - name: wget -O /etc/yum.repos.d/ownsource.repo http://www.comingchina.com:8080/testing/ownsource/ownsource.repo
        - unless: test -f /etc/yum.repos.d/ownsource.repo
                                                                                                           
zeromqs:
    pkg.installed:
        - pkgs:
            - zeromq
            - libzmq3
            - python26-zmq
        - require:
            - cmd: getownsourcerepo
                                                                                                           
salt-minion:
    service.running:
        - enable: True
        - watch:
            - pkg: zeromqs

放在/etc/salt/updatezeromq.sls，然後先找一臺機器測試一下：

1
salt '192.168.1.102' state.sls updatezeromq

哇，好神奇，這樣就可以更新了，等命令跑完，看一下版本，還是沒變，擦，這是什麼情況，認真看了一下日誌，是zeromq python26-zmq這兩個包已經存在，沒有升級，於是找了一下文件，看看pkg.installed 怎麼升級軟體，突然發現原來還可以指定版本的，果斷把sls檔案改成：

    cmd.run:
        - name: wget -O /etc/yum.repos.d/ownsource.repo http://www.comingchina.com:8080/testing/ownsource/ownsource.repo
        - unless: test -f /etc/yum.repos.d/ownsource.repo
zeromqs:
    pkg.installed:
        - pkgs:
            - zeromq: 3.2.2-13.1
            - libzmq3
            - python26-zmq: 13.1.0-1
        - require:
            - cmd: getownsourcerepo
salt-minion:
    service.running:
        - enable: True
        - watch:
            - pkg: zeromqs

終於順利升級成功！感覺玩這東西還真不容易。。。
