zabbix-agent 一键安装脚本

1. 前期准备

• 离线安装包

  • ubuntu deb包

  • centos rpm包

• samba配置

  • 共享windows文件夹，可挂载

• 配置文件

  • 提前配置代理指向位置，避免出错

2. 脚本

#!/bin/bash
# 00.vars
mount_share_dir=“挂载路径”
mount_dir=/mnt
agent_dir=$mount_dir/package/
conf_dir=$mount_dir/conf
# 01.mount
mount  $mount_share_dir  $mount_dir
# 02.select proxy
cat <<EOF
请选择您需要配置的指向代理：
                                01 - ***
                                02 - ***
                                03 - ***
                                04 - ***
EOF

# 03.chk num
