查看“Salt安装”的源代码

==pre==
master 192.168.23.50

client 192.168.20.208

  个人观点puppet最大缺点就是默认情况下Agent每隔30分钟向master同步状态，master主动推送功能比较薄弱(2.7版本），ansible基于SSH服务执行，如果服务器过多不建议使用，他是使用轮训的方式。Salt基于消息队列。性能相当好，适合大量生产环境。

=== salt-ssh批量安装minion===
<pre>
  yum install salt-ssh  
  可以用key   --key-deploy        Set this flag to attempt to deploy the authorized ssh

但是必先   Are you sure you want to continue connecting (yes/no)?

[https://www.cnblogs.com/yanjieli/p/10912572.html salt-ssh ]

==防火墙规则 ==
注意 这个才是对的 比较 安全的 
在主控端添加(所有 minion)TCP 4505,TCP 4506 的规则，而在被控端无须配置防火墙，原理是被控端直接与主控端的zeromp建立链接接收

===1.on master ===
 #salt-master服务需要监听4045和4046端口，因此需要开放这两个端口 一般加这个就行了 小伙伴今天又加反了 哈哈 2020
 iptables -I INPUT -s minion_ip -p tcp -m multiport --dports 4505,4506 -j ACCEPT

  #Allow Salt to communicate with Master on the loopback interface
 iptables -A INPUT -i lo -p tcp -m multiport --dports 4505,4506 -j ACCEPT

===2.on minion===
 iptables -I INPUT -s 192.168.30.94 -p tcp -m multiport --dports 4510,4511 -j ACCEPT



<pre>
#这个平时一般为了删除而查看 哈哈
iptables -L -n --line-number |grep 21 # //--line-number可以显示规则序号，在删除的时候比较方
iptables -D INPUT 3 # //删除input的第3条规则
iptables -R INPUT 3 -j DROP # //将规则3改成DROP

##官方的写得有点开放 不太好 
为SALT开启防火墙配置
http://docs.saltstack.cn/topics/tutorials/firewall.html
http://yango.iteye.com/blog/2264641

RHEL 6 / CENTOS 6
一些Linux发行版带有的``lokkit``命令行软件可以很简单的通过命令行打开iptables防火墙的端口。只是需要小心不要太粗心而关闭了ssh端口。

lokkit范例：
lokkit -p 22:tcp -p 4505:tcp -p 4506:tcp

#iptables 
iptables -A INPUT -m state --state new -m tcp -p tcp --dport 4505 -j ACCEPT
iptables -A INPUT -m state --state new -m tcp -p tcp --dport 4506 -j ACCEPT


MASTER端白名单

# Allow Minions from these networks
iptables -I INPUT -s 192.168.1.0/22 -p tcp -m multiport --dports 4505,4506 -j ACCEPT
-I INPUT -s 10.1.2.0/24 -p tcp -m multiport --dports 4505,4506 -j ACCEPT
-I INPUT -s 10.1.3.0/24 -p tcp -m multiport --dports 4505,4506 -j ACCEPT
# Allow Salt to communicate with Master on the loopback interface
-A INPUT -i lo -p tcp -m multiport --dports 4505,4506 -j ACCEPT
# Reject everything else
-A INPUT -p tcp -m multiport --dports 4505,4506 -j REJECT</pre>

==配置key==
<pre>在master端通过salt-key -L查看Keys如下：
[root@vm1 test]# salt-key -L
Accepted Keys:
Unaccepted Keys:
test1
Rejected Keys:
[root@vm1 test]# salt-key -A
Key for minion test1 accepted.

[root@vm1 test]# salt 'test1' test.ping 
test1:
True

显示所有minion的认证信息
salt-key  -L

接受所有 Unaccepted Keys 状态的minion的认证信息
salt-key  -A

# 接受192.168.30.100的认证信息，不需要手动验证
salt-key -a 192.168.30.100 -y


# 拒绝认证192.168.0.100
salt-key -d 192.168.0.100
 
#删除单个  有时minion 挂掉 是因为key 重名了 
salt-key  -d prod-web01 然后重启minion

# 拒绝所有 Unaccepted Keys 状态的minion
salt-key -D

</pre>

==常用命令==
<pre>
1)检查master与minion的连接状态：salt '*' test.ping or salt 'test1' test.ping
2)远程执行命令：salt '*' cmd.run 'ls /root'
test1:
anaconda-ks.cfg
bootstrap-salt.sh
install.log
install.log.syslog
vm2

3)从master上传文件至minion：
salt-cp nodeid source_file target_file
例子：salt-cp 'vm01' /root/test/bootstrap-salt.sh /root
4)master同步命令：
salt '*' state.highstate

To have the Minion start automatically at boot time:
chkconfig salt-minion on
#7
systemctl enable salt-minion.service
to start the Minion:
#7
systemctl start salt-minion.service

==遇到问题==
<pre>
2017
[root@da ~]# /etc/init.d/salt-master restart 
Stopping salt-master daemon:                               [FAILED]

                                                           [FAILED]

打开blind ip 
# The address of the interface to bind to:
interface: 0.0.0.0


问题1
[root@localhost soft]# yum install python-jinja2
Loaded plugins: fastestmirror, security
Determining fastest mirrors
Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

编辑/etc/yum.repos.d/epel.repo和/etc/yum.repos.d/epel-testing.repo
将mirrorlist注释，将baseurl打开

问题2：
file /usr/lib64/python2.6/zipfile.pyo from install of python-libs-2.6.6-64.el6.x86_64 conflicts with file from package python-2.6.6-29.el6_2.2.x86_64
64 conflicts with file from package python-2.6.6-36.el6.x86_64
Error Summary 

升级下python版本
yum update python or yum install python

问题其一
minion 有这些log 加上 salt-key -L 为空 
017-08-04 16:35:57,645 [salt.utils.parsers            ][WARNING ][5761] Minion received a SIGTERM. Exiting.

记录配置 master ip on master 好搞笑 各种搞错了 笨蛋

[root@ ~]# cat  /etc/salt/minion    |  grep -v   \^# | grep -v \^$
master:  10.10.1.25
master_port: 4506
id: ad_web
tcp_pub_port: 4510
tcp_pull_port: 4511


问题其二 
To repair this issue, delete the public key for this minion on the Salt Master and restart this minion.
Or restart the Salt Master in open mode to clean out the keys. The Salt Minion will now exit.

原因：
大概的意思就是，minion端拿到的key与master端的不符，验证无法通过。
解决方法是删除minion端的key，再重新与master进行连接和认证。

on master上删除key
/etc/salt/pki/master/minions

如果实在不行 就把minion的也删除了
解决方法是删除minion端的key，再重新与master进行连接和认证
