1.masterless配置
1.1修改配置文件minion
- 注释master行
- 取消注释file_client并设其值为local
- 设置file_roots
- 设置pillar_roots
[root@localhost ~]# vi /etc/salt/minion
....
#master: salt
file_client: local
file_roots:
base:
- /srv/salt/base
prod:
- /srv/salt/prod
pillar_roots:
base:
- /srv/pillar/base
prod:
- /srv/pillar/prod
1.2关闭salt-minion服务
[root@localhost ~]# systemctl disable --now salt-minion
[root@localhost ~]# systemctl status salt-minion
● salt-minion.service - The Salt Minion
Loaded: loaded (/usr/lib/systemd/system/salt-minion.service; disabled; vendor preset: disabled)
Active: inactive (dead)
Docs: man:salt-minion(1)
file:///usr/share/doc/salt/html/contents.html
https://docs.saltstack.com/en/latest/contents.html
1.3salt-call
masterless模式执行模块或状态时需要使用salt-call命令，而不再是salt或者salt-ssh。需要注意的是要使用salt-call的–local选项。
[root@localhost ~]# salt-call --local cmd.run 'ls /root'
local:
anaconda-ks.cfg
[root@localhost ~]# salt-call --local cmd.run 'uptime'
local:
17:36:43 up 4:17, 2 users, load average: 0.00, 0.01, 0.05
启动apache服务
[root@localhost base]# pwd
/srv/salt/base
[root@localhost base]# mkdir apache
[root@localhost base]# cd apache/
[root@localhost apache]# vi init.sls
apache-install:
pkg.installed:
- name: httpd
apache-service:
service.running:
- name: httpd
- enable: True
[root@localhost base]# salt-call --local state.sls apache.init

2.salt-master高可用
用node01和node02当maser，node03当minion
[root@node01 ~]# yum -y install salt-master

[root@node03 ~]# yum -y install salt-minion
已加载插件：product-id, search-disabled-repos, subscription-manager
This system is not registered with an entitlement server. You can use subscription-manager to register.
在node03上修改配置文件.重启minion
[root@node03 ~]# tail /etc/salt/minion
master:
- 192.168.100.131
- 192.168.100.132
master_type: failover
[root@node03 ~]# systemctl restart salt-minion
在master上接受等待的key
[root@node01 ~]# salt-key -L
Accepted Keys:
Denied Keys:
Unaccepted Keys:
node03
Rejected Keys:
[root@node01 ~]# salt-key -Ay
The following keys are going to be accepted:
Unaccepted Keys:
node03
Key for minion node03 accepted.
[root@node01 ~]# salt-key -L
Accepted Keys:
node03
Denied Keys:
Unaccepted Keys:
Rejected Keys:
测试连通性
[root@node01 ~]# salt '*' test.ping
node03:
True
在node01的master上开启master_sign_pubkey
[root@node01 ~]# vi /etc/salt/master
..此处省略
master_sign_pubkey: True
···此处省略
然后在/etc/salt/pki/上就有master_sign.pem和master_sign.pub
[root@node01 pki]# tree /etc/salt/pki/
/etc/salt/pki/
├── master
│ ├── master.pem
│ ├── master.pub
│ ├── master_sign.pem
│ ├── master_sign.pub
│ ├── minions
│ │ └── node03
│ ├── minions_autosign
│ ├── minions_denied
│ ├── minions_pre
│ └── minions_rejected
└── minion
├── minion_master.pub
├── minion.pem
└── minion.pub
然后将node01的/etc/salt/pki/master/master_sign.pem和/etc/salt/pki/master/master_sign.pub 和/etc/salt/pki/master/master_sign.pub 传到node02上面去
[root@node01 pki]# scp /etc/salt/pki/master/master_sign.pem [email protected]:/etc/salt/pki/master/
[root@node01 pki]# scp /etc/salt/pki/master/master_sign.pub [email protected]:/etc/salt/pki/master/
[root@node01 pki]# scp /etc/salt/master [email protected]:/etc/salt/master
然后在node02上重启服务,查看已经传过来了
[root@node02 pki]# systemctl restart salt-master
[root@node02 pki]# tree /etc/salt/pki/
/etc/salt/pki/
├── master
│ ├── master.pem
│ ├── master.pub
│ ├── master_sign.pem
│ ├── master_sign.pub
│ ├── minions
│ ├── minions_autosign
│ ├── minions_denied
│ ├── minions_pre
│ │ └── node03
│ └── minions_rejected
└── minion
├── minion_master.pub
├── minion.pem
└── minion.pub
然后将node01的/etc/salt/pki/master/master_sign.pub 传到minionnode03上面去
[root@node01 pki]# scp /etc/salt/pki/master/master_sign.pub [email protected]:/etc/salt/pki/minion/
[root@node03 ~]# tree /etc/salt/minion
/etc/salt/minion [error opening dir]
0 directories, 0 files
[root@node03 ~]# tree /etc/salt/pki/minion/
/etc/salt/pki/minion/
├── master_sign.pub
├── minion_master.pub
├── minion.pem
└── minion.pub
然后设置node03的配置文件,重启服务
[root@node03 ~]# tail /etc/salt/minion
#event_match_type: startswith
master:
- 192.168.100.131
- 192.168.100.132
master_type: failover
master_shuffle: True
master_alive_interval: 1
verify_master_pubkey_sign: True
alway_verify_signature: True
[root@node03 ~]# systemctl restart salt-minion
在node03测试一下
[root@node03 ~]# salt-minion -l debug
/usr/lib/python2.7/site-packages/salt/scripts.py:212: DeprecationWarning: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won’t be maintained after that date. Salt will drop support for Python 2.7 in the Sodium release or later.

然后进行测试,当在node上ping通的时候。node01就ping不通
[root@node02 pki]# salt ‘’ test.ping
node03:
True
[root@node01 pki]# salt '’ test.ping
node03:
Minion did not return. [No response]
当我把node02的服务停了之后，node01就能ping通
[root@node02 pki]# systemctl stop salt-master
[root@node01 pki]# salt ‘*’ test.ping
node03:
True
### 3.salt-syndic部署

### 3.2 安装软件
在syndic上安装salt-master和salt-syndic

### 3.3 配置master
在master的配置文件将order_master的值设为True
[root@node01 ~]# vim /etc/salt/master
…此处省略N行
Set the order_masters setting to True if this master will command lower
masters’ syndic interfaces.
order_masters: True
### 3.4配置syndic
在syndic的配置文件上将syndic_master的值设为master的IP
[root@node02 ~]# vi /etc/salt/master
…此处省略N行
Set the order_masters setting to True if this master will command lower
masters’ syndic interfaces.
syndic_master: 192.168.100.131
### 3.5配置minion
在minion上将master指向syndic所在主机
[root@node03 salt]# tail -1 /etc/salt/minion
master: 192.168.100.133
### 3.6在syndic上接受minion主机的key
[root@node02 ~]# salt-key -L
Accepted Keys:
Denied Keys:
Unaccepted Keys:
node03
Rejected Keys:
[root@node02 ~]# salt-key -A
The following keys are going to be accepted:
Unaccepted Keys:
node03
Proceed? [n/Y] Y
Key for minion node03 accepted.
[root@node02 ~]# salt-key -L
Accepted Keys:
node03
Denied Keys:
Unaccepted Keys:
Rejected Keys:
### 3.7 在master上接受syndic主机的key
[root@node01 ~]# salt-key -L
Accepted Keys:
Denied Keys:
Unaccepted Keys:
node02
Rejected Keys:
[root@node01 ~]# salt-key -A
The following keys are going to be accepted:

Proceed? [n/Y] y
Key for minion node02 accepted.
[root@node01 ~]# salt-key -L
Accepted Keys:
node02

### 3.8 在master上去ping一下
发现master进行的ping的时候是minion端进行答应，而不是syndic
[root@node01 ~]# salt ‘*’ test.ping
node03:
True
