需求：经常对线上服务器做一些修改配置文件，搭建等操作，很麻烦
系统环境是RHEL5
安装过程和很多网友一样，先安装epel
rpm -Uvh http://mirror.pnl.gov/epel/5/x86_64/epel-release-5-4.noarch.rpm yum update yum install salt-minion yum install salt-master
安装过程巨简单，装好后，因为saltstack 是用zeromq来进行通信的，minion运行的时候log报错，[WARNING ] You have a version of ZMQ less than ZMQ 3.2! There are known connection keep-alive issues with ZMQ < 3.2 which may result in loss of contact with minions. Please upgrade your ZMQ!
解决办法：
http://copr-be.cloud.fedoraproject.org/results/saltstack/zeromq4/epel-5-x86_64/python-zmq-14.3.1-3.el5/python26-zmq-14.3.1-3.el5.x86_64.rpm
rpm -Uvh python26-zmq-14.3.1-3.el5.x86_64.rpm zeromq-4.0.4-2.el5.x86_64.rpm
由于安装的版本是7.1，有个bug ，log日志如下
Starting salt-master daemon: Traceback (most recent call last): File "/usr/bin/salt-master", line 10, in <module> salt_master() File "/usr/lib/python2.6/site-packages/salt/scripts.py", line 20, in salt_master master.start() File "/usr/lib/python2.6/site-packages/salt/__init__.py", line 114, in start if check_user(self.config['user']): File "/usr/lib/python2.6/site-packages/salt/utils/verify.py", line 296, in check_user if user in e.gr_mem] + [pwuser.gid]) AttributeError: 'pwd.struct_passwd' object has no attribute 'gid'
解决办法：重新编译saltstack
wget https://github.com/saltstack/salt/archive/develop.zip unzip develop cd salt-develop/ python2.6 setup.py install
重启服务后，master和minion 正常通信
