ssh互信自动化脚本（待更新）

1.建立一个ip，端口，用户，密码列表

[root@localhost shell-key]# cat arg_list.txt
172.16.56.237 clouds root   172.16.56.215
172.16.56.53  clouds  root  172.16.56.215
172.16.56.215 clouds root  172.16.56.215
[root@localhost shell-key]# 

2.建立expect交互交脚本：

[root@localhost shell-key]# cat expect_run_config.exp
#!/usr/bin/expect -f
set ip [lindex $argv ]
set passwd [lindex $argv ]
set username [lindex $argv ]
set port [lindex $argv ]
set localip [lindex $argv ]
set ssh_file [lindex $argv ]
 
set remo_ip [lindex $argv ]
set key_name [lindex $argv ]
set timeout  
 
#
#create the key in the every node
#生成公共密钥
 
spawn ssh $username@$ip
expect {
"*yes/no" { send "yes\r"; exp_continue}
"*password:" { send "$passwd\r" }
}  
 
expect "*#\n"
send "rm -fr /root/.ssh\r"
send "mkdir /root/.ssh\r"
send "chmod 700 /root/.ssh\r"
send "cd /root/.ssh\r"
send "ssh-keygen\r"
 
expect "*_rsa):"
send "\r"
expect "*ase):"
send "\r"
expect "*again:"
send "\r"
 
expect "#\n"
send  "exit\r"
expect eof  
 
spawn ssh $username@$remo_ip
 
expect {
"*yes/no" { send "yes\r"; exp_continue}
"*password:" { send "$passwd\r" }
}
 
expect "*#\n"
send "scp /root/.ssh/id_rsa.pub $username@$localip:/root/shell-key/pub_key/$key_name\r"
expect "*(yes/no)?"
send "yes\r"
 
expect "*password: \n"
send "$passwd\r"
 
#expect "*password:\n"
#send "$passwd\r"
 
expect "*#\n"
send  "exit\r"
expect eof
 
[root@localhost shell-key]# 

3.建立一个shell循环脚本：

[root@localhost shell-key]# cat loop-out.sh
#!/bin/sh
#loop_sh.sh
echo "########******loding*******#########"
rm -fr /root/shell-key/pub_key/*
rm -fr /root/shell-key/hello.txt
 
while read line
do
    echo $line  >> hello.txt
done < arg_list.txt
sleep 3
 
rm -fr /root/shell-key/exp_list.txt
 
while read sl
do
    echo $sl | sed "s/$/ ${RANDOM}.key/" >> exp_list.txt
done < hello.txt
 
sleep 3
 
while read list
do
    echo $list | awk '{print $1}'
    rem_ip=$(echo $list | awk '{print $1}')
    rem_keyname=$(echo $list | awk '{print $6}')
    ./expect_run_config.exp $list $rem_ip $rem_keyname
done < exp_list.txt
 
cat /root/shell-key/pub_key/* > /root/.ssh/authorized_keys
 
if [ $? -eq 0 ];then
        echo "******************************************"
        echo "Congratulations, you create a public key *"
        echo "******************************************"
else
        echo "Please check_your script $0 and expect config! "
        echo "Good luck !"
fi
[root@localhost shell-key]#

4.执行脚本：

[root@localhost shell-key]# ./loop-out.sh
