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.rpmyum install salt-masterchkconfig salt-master onservice salt-master start
二、客户端的安装：
rpm -Uvh http://mirror.pnl.gov/epel/5/i386/epel-release-5-4.noarch.rpmyum install salt-minionchkconfig salt-minion on#修改/etc/salt/minion配置：master: 192.168.1.100 #服务端IPid: 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-minionservice 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.repoyum clean allyum update zeromq libzmq3 python26-zmqservice 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.repozeromqs: pkg.installed: - pkgs: - zeromq: 3.2.2-13.1 - libzmq3 - python26-zmq: 13.1.0-1 - require: - cmd: getownsourcereposalt-minion: service.running: - enable: True - watch: - pkg: zeromqs
再来一次：

终于顺利升级成功！感觉玩这东西还真不容易。。。
