Saltstack
类似于puppet
salt的核心功能
使用命令 发送到远程系统是并行的而不是串行的
使用安全加密的协议
使用最小最快的网络载荷
提供简单的编程接口
Python编写，相当轻量级
通讯层采用zeromq
安装：
master：
[root@yz6205 ~]# yum -y install epel-release
[root@yz6205 ~]# rpm -q epel-release
epel-release-6-8.noarch
[root@yz6205 ~]# yum -y install salt-master
[root@yz6245 ~]# salt '*' test.ping
minion-yz6205:
True
[root@yz6245 ~]# salt 'minio?-yz6205' test.ping
minion-yz6205:
True
正则表达式
[root@yz6245 ~]# salt -E '(minion|minion)-yz6205' test.ping
minion-yz6205:
True
客户端只有一台，所以只出现一条
[root@yz6245 ~]# cat /etc/salt/states/top.sls
base:
'minion.yz205':
- match: pcre #支持正则表达式来匹配
- init.pkg
问题：
