expect+TCL实现批量机器SSH免登录

my2005lb

分享一段expect+TCL自动化代码，作用是在在任何一台Linux机器执行对其他Linux节点的免密码登录SSH：

1. #!/usr/bin/expect
   
2. set ip [lindex $argv 0]
   
3. set passwd [lindex $argv 1]
   
4. spawn scp /root/.ssh/authorized_keys  root@$ip:/root/.ssh/authorized_key1
   
5. set i 1
   
6. while {$i<3} {
   
7.   expect {
   
8.     "password" {send "$passwd\n";set i 4}
   
9.     "yes" {send "yes\n"}
   
10.   }
    
11. }
    
12. expect eof
    
13. 
    
14. spawn ssh root@10.1.1.1
    
15. set j 1
    
16. while {$j<3} {
    
17. expect {
    
18.    "password" {send "abc123\n";set j 4}
    
19.    "yes"  {send "yes\n"}
    
20.    "]#" {send "exit\n"; set j 4}
    
21. }
    
22. }
    
23. expect "#"
    
24. send "hostname\n"
    
25. expect "#"
    
26. send "cat /root/.ssh/authorized_key1 >> /root/.ssh/authorized_keys\r"
    
27. expect "#"
    
28. send "exit\n"
    
29. expect eof
