使用salt-ssh批量管理主机

Posted 2020-09-05

安装salt-ssh：yum install -y salt-master salt-ssh
master配置文件：cat /etc/salt/master
file_roots:
  base:
    - /srv/salt/
  dev:
    - /srv/salt/dev/services
    - /srv/salt/dev/states
  prod:
    - /srv/salt/prod/services
    - /srv/salt/prod/states
top.sls文件：cat /srv/salt/top.sls
base:
  ‘roles:nginx‘:
    - match: grain
    - init.pkg
    - init.limit
limit文件：cat /srv/salt/init/limit.sls
limit-conf-config:
  file.managed:
    - name: /tmp/limits.conf
    - source: salt://init/files/limits.conf
    - user: root
    - group: root
    - mod: 644
    - name: /tmp/df.sh
    - source: salt://init/files/df.sh
    - user: root
    - group: root
    - mod: 644
files目录：ls /srv/salt/init/files
df.sh  limits.conf
df.sh文件：cat /srv/salt/init/files/df.sh
#!/bin/bash
hostname
roster文件：cat /etc/salt/roster
test1.discuz.com:
  host: test1.discuz.com
  user: root
  passwd: redhat
test2.discuz.com:
  host: test2.discuz.com
  user: root
  passwd: redhat
tomcat1.discuz.com:
  host: tomcat1.discuz.com
  user: root
  passwd: centos
tomcat2.discuz.com:
  host: tomcat2.discuz.com
  user: root
  passwd: centos
  
传送文件到各主机：salt-ssh ‘*‘ state.sls init.limit
在各主机执行脚本：salt-ssh ‘*‘ cmd.run ‘bash /tmp/df.sh‘
生成roster脚本
roster.sh文件：cat /root/roster.sh
#!/bin/bash
>/etc/salt/roster
IFS=‘ ‘
cat /root/hosts | while read line
do
   arr=($line)
   echo ${arr[0]}":">>/etc/salt/roster
   echo "  host: "${arr[0]}>>/etc/salt/roster
   echo "  user: "${arr[1]}>>/etc/salt/roster
   echo "  passwd: "${arr[2]}>>/etc/salt/roster
done
hosts文件：cat /root/hosts
test1.discuz.com root redhat
test2.discuz.com root redhat
tomcat1.discuz.com root centos
tomcat2.discuz.com root centos
