【Linux】saltstack 安装及简单使用
准备三台server，一台为master(10.96.20.113)，另两台为minion(10.96.20.117,10.96.20.118)
主机名（master、minion1、minion2）、IP配置好（10.96.20.113、10.96.20.117、10.96.20.118）
master-side和minion-side：
[root@master ~]# uname -rm
2.6.32-431.el6.x86_64 x86_64
[root@master ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.5(Santiago)
[root@master ~]# yum -y install python-requests PyYAML python-crypto python-jinja2 #（先使用CentOS6-Base-163.repo或其它yum源安装好这几个包，再用epel源安装salt-master，因为epel源中缺少这几包导致安装会报如下错）
……
Error: Package:salt-2015.5.10-2.el6.noarch (epel)

Youcould try using --skip-broken to work around the problem
Youcould try running: rpm -Va --nofiles --nodigest

举例（增加需求，各minion的httpd port号不一致；业务数据应独立存放，/srv/salt/apache/deploy.sls中仅存放业务处理逻辑，/srv/pillar/apache/pillar_deploy.sls中存放数据）：

注：
主机名一定要能解析到master和所有minion（#hostname所得出的主机名，主机名最好为fqdn）
生产环境复杂，不要开启自动认证功能（auto_accept: False）；
minion-side在每次启动时会在minion-side的/etc/salt/pki/minon/下生成minion.pem（private key）和minion.pub（public key），并将minion.pub发给master-side，经master-side认证（#salt-key-a MINION_ID）之后会放在master-side的/etc/salt/pki/master/minions/下（此目录下存放所有认证过的minion，以minion_id为文件名）；同时minion-side的/etc/salt/pki/minion/下存放master-side的public key（文件名为minion_master.pub）；以此双方实现互相认证；
minion-side与master-side的4505port保持长连接，如果断了会自动重连，所以执行操作很快；
file_roots中的base（默认/srv/salt/）定义的是基础环境，在其下按不同部门或业务，对应的创建不同的目录，规划好，例如/srv/salt/init/下放所有server都要执行的操作；
/srv/salt/top.sls（在/etc/salt/master中定义state_top:top.sls，定义在什么环境下，哪些server，该做什么事；The state system uses a "top" file to tell the minionswhat environment to use and what modules to use. The state_top file is definedrelative to the root of the base environment as defined in "File Serversettings" below.）；
