写在前面
- CentOS Linux release 7.9.2009 (Core) 系统已验证
- 默认root账户, 其他账户无效
- 创建[auto_mm.sh]必须vi创建文件然后粘贴
1.安装expect
1.1.在线安装
yum install -y tcl
yum install -y expect1.2.离线安装(选其中一个即可)
1.2.1.在能联通公网的机器导出rpm包到不能联通公网的机器安装
参考 shell(30) : yum导出依赖包并离线安装_yum 导出包-CSDN博客
repotrack expect
1.2.2.百度网盘下载
待补充 ...
1.2.3.CSDN下载
待补充 ...
2.填下ip和密码信息(填好直接粘贴即可)
cat > ips <<'EOF'
192.168.1.1 abc123
192.168.1.2 abc123
EOF
若执行失败则创建ips文件, 填入以下内容
192.168.1.1 abc123
192.168.1.2 abc1233.创建执行脚本 auto_mm.sh , 粘贴以下
