saltstack学习一：安装与升级

由于我的服务器是centos5，安装后还要把zeromq升级，有点蛋疼

一：服务端的安装：

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、客户端的安装：

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   #服务端IP
id: 192.168.1.101       #标识，我用本机IP做标识
service salt-minion start

起始以为就这样快乐的安装完了，但测试过程中发现minion端会产生一个僵尸进程，问了群上的大神绿肥才知道这是一个BUG，要把minion端升级到2014.1.1版本：

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

这样僵尸进程的BUG总算解决了，后来网上一看原来centos5安装salt还有一个BUG，就是zeromq的版本太低，还需要升级一下，于是又找到这个办法来升级：

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

检查一下版本：

[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

确实是升级成功了，于是后面就想用salt的state功能来完成剩下机器的升级，可是不会弄呀，果断网上抄一份配置：

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，然后先找一台机器测试一下：

salt '192.168.1.102' state.sls updatezeromq

哇，好神奇，这样就可以更新了，等命令跑完，看一下版本，还是没变，擦，这是什么情况，认真看了一下日志，是zeromq python26-zmq这两个包已经存在，没有升级，于是找了一下文档，看看pkg.installed 怎么升级软件，突然发现原来还可以指定版本的，果断把sls文件改成：

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: 3.2.2-13.1
            - libzmq3
            - python26-zmq: 13.1.0-1
        - require:
            - cmd: getownsourcerepo
salt-minion:
    service.running:
        - enable: True
        - watch:
            - pkg: zeromqs

再来一次：
