master的配置安装
查看CentOS版本和其内核版本及安装配置阿里云yum源
[root@master ~]# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)
[root@master ~]# uname -r
3.10.0-862.el7.x86_64
[root@master ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
安装epel-release和salt-master工具包
[root@master ~]# yum install epel-release -y
[root@master ~]# yum install salt-master -y
配置saltstack开机自启动服务
[root@master ~]# systemctl enable salt-master.service
启动saltstack master 服务
[root@master ~]# systemctl start salt-master.service
检查saltstack端口及进程的运行状态，其中4505是saltstack管理服务器发送命令消息的端口，4506是消息返回时所用的端口。saltstack一般是会启动多个进程来进行不同工作的。
[root@master ~]# netstat -tunlp | grep python

关闭防火墙
[root@master ~]# systemctl disable firewalld.service
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
修改selinux为Permissive模式
[root@master ~]# setenforce 0
[root@master ~]# getenforce
Permissive
minion的配置安装
查看CentOS版本和其内核版本及安装配置阿里云yum源
(同master)
安装epel-release和salt-master工具包
[root@slave1 ~]# yum install epel-release -y
[root@slave1~]# yum install salt-minion-y
在minion端配置master
[root@slave1 ~]# vi /etc/salt/minion
master: master (大概再17行的位置)
配置开机minion开启自启动服务
[root@slave1 ~]# systemctl enable salt-minion.service
启动salt-minion服务
[root@slave1 ~]# systemctl start salt-minion.service
关闭防火墙服务
[root@slave1 ~]# systemctl disable firewalld.service
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@slave1 ~]# systemctl stop firewalld.service
查看salt-minion进程的启动状况
[root@slave1 ~]# ps -ef | grep salt | grep -v grep
root 1360 1 0 10:55 ? 00:00:00 /usr/bin/python /usr/bin/salt-minion
root 1967 1360 0 11:10 ? 00:00:00 /usr/bin/python /usr/bin/salt-minion
按照以上方法配置slave2, slave3...
具体操作
设置auto_accept为True
[root@master ~]# vi /etc/salt/master
auto_accept: True (位置比较靠中间，多搜索几下)
[root@master ~]# salt-key -L
Accepted Keys:
slave1
slave2
slave3
Denied Keys:
Unaccepted Keys:
Rejected Keys:
[root@master ~]# cd /etc/salt/pki/master/
[root@master master]# ls
master.pem master.pub minions minions_autosign minions_denied minions_pre minions_rejected
[root@master master]# cd minions
[root@master minions]# ls
slave1 slave2 slave3
[root@master minions]# cat slave1
