一鍵部署Saltstack腳本

最近一批新機器需要安裝Saltstack，由於操作系統版本之繁雜，涉及到的問題之多，索性寫了個腳本，一鍵運行安裝，解決所有操作系統遇到的問題，省去重複工作的時間。

#!/bin/bash
#腳本使用的時候注意，運行到最後檢查minion_id的ip是否正確，此處取的ip只是第一行，但第一行不一定是本機IP，另外，安裝的salt-minion是2018.3.3版本的
HOSTNAME=$(hostname) #主機名
HOST_IP=$(ifconfig -a|grep inet|grep -v 127.0.0.1|grep -v inet6|awk '{print $2}'|tr -d "addr:"| awk "NR==1") #主機IP
SYS_VER=$(cat /etc/redhat-release) #操作系統版本
DIR=$(pwd) #當前目錄
function common(){   #所有操作系統（除了suse）通用的步驟
   cd /etc/yum.repos.d/
   yum clean all
   yum makecache
   yum install salt-minion
   cd $DIR
   wget http://xxxxxx/mirrors/saltstack/yum/redhat/6/x86_64/minion
   cp minion /etc/salt/minion
   sed -i "s/client_ehp4/${HOSTNAME}_${HOST_IP}/g" /etc/salt/minion
   service salt-minion start

}
