更改脚本权限(可执行):
[root@jumpserver jumpserver]# chmod 755 jumpserver.sh
[root@jumpserver jumpserver]# chown root.root /home/jumpserver/jumpserver.sh
说明: 至此跳板机以搭建完成,以下是一些菜单选项,可以根据个人需求选择使用!!!
使用本菜单选项的方法:将上面jumpserver.sh脚本中“登录界面”下的参数换成下面的参数即可。

------------------------------跳板机帮助手册---------------------------------
(1)回车或输入"命令菜单"以外的任意字符,是退出跳板机服务。
(2)命令菜单"0"自定义跳转(即:ssh 任意ip)
(3)菜单1以上的选项是服务器列表,这里只有12台服务器提供选择。
(4)跳板机上面服务器包含:各项目存储服务器,日志服务器,应用服务。
-----------------------------------------------------------------------------
以下为命令菜单,请选择:
**0)(自定义输入服务器ip、账号和密码等)

说明: 该文件的作用是设定在使用jumpserver.sh时的跳板机验证标识。
以下内容只在普通用户测试使用。。。
在/home/junpserver目录下创建file_useradd.txt:
[root@jumpserver jumpserver]# vim file_useradd.txt
#文件内容格式:账号 密码
192.168.8.130 123456
之后直接执行脚本即可!
[root@jumpserver jumpserver]# vim /home/jumpserver/ssh-key-add.sh
#!/bin/bash
#定义账号密码:
#PWDD='XXXX'
#定义账号密码文件(必须修改)
