1. 主机规划| 服务器名称 | 操作系统版本 | 内网IP | 外网IP(模拟) | Hostname | 部署模块 |
|---|---|---|---|---|---|
| salt100 | CentOS7.5 | 172.16.1.100 | 10.0.0.100 | salt100 | salt-master、salt-minion |
| salt01 | CentOS7.5 | 172.16.1.11 | 10.0.0.11 | salt01 | salt-minion |
| salt02 | CentOS7.5 | 172.16.1.12 | 10.0.0.12 | salt01 | salt-minion |
| salt03 | CentOS7.5 | 172.16.1.13 | 10.0.0.13 | salt01 | salt-minion |
salt100、salt01、salt02、salt03的hosts文件都追加如下信息。
这样主机名相互之间可以解析。
[root@salt100 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.16.1.11 salt01
172.16.1.12 salt02
172.16.1.13 salt03
172.16.1.14 salt04
172.16.1.15 salt05
172.16.1.100 salt1001、 运维人员使用的登录账号；
2、 所有的业务都放在 /app/ 下「yun用户的家目录」，避免业务数据乱放；
3、 该用户也可用于后期salt-ssh使用，因为几乎所有的生产环境都是禁止root远程登录的（因此进行了 sudo 提权）。
# 使用一个专门的用户，避免直接使用root用户
# 添加用户、指定家目录并指定用户密码
useradd -u 1050 -d /app yun && echo ‘123456‘ | /usr/bin/passwd --stdin yun
# sudo提权
echo "yun ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers
# 让其它普通用户可以进入该目录查看信息
chmod 755 /app/监控

在salt100、salt01、salt02、salt03机器上执行
yum install -y https://repo.saltstack.com/yum/redhat/salt-repo-latest-2.el7.noarch.rpm根据规划在salt100安装salt的master和minion，在其他机器安装salt的minion。
yum install -y salt-master salt-minion yum install -y salt-minion [root@salt100 ~]# salt --version # master版本查看
salt 2018.3.3 (Oxygen)
[root@salt100 ~]# salt-minion --version # minion版本查看
salt-minion 2018.3.3 (Oxygen)在salt100上执行，无需任务配置修改
[root@salt100 ~]# systemctl start salt-master.service 1、 minion端指向的master是哪个
2、 minion端的ID是什么
[root@salt100 salt]# pwd
/etc/salt
[root@salt100 salt]# vim minion
………………
# 可以是IP或者hostname
# 如果是hostname那么必须能够解析【最佳实践配置为 主机名】
master: salt100
………………
# Explicitly declare the id for this minion to use, if left commented the id
# will be the hostname as returned by the python call: socket.getfqdn()
# Since salt uses detached ids it is possible to run multiple minions on the
# same machine but with different ids, this can be useful for salt compute
# clusters.
# 如果id不配置，那么默认为hostname
# 如果下次要更改该配置，那么要把 /etc/salt/minion_id 也给删除掉，并重启客户端【会生成一个新的minion_id】
#id:
………………[root@salt100 ~]# systemctl start salt-minion.service systemctl enable salt-master.servicesystemctl enable salt-minion.service[root@salt100 salt]# pwd
