Shell腳本+expect批量部署ssh
一、準備工作及思路
1，三臺機器做實驗（centos6.5、IP：192.168.0.22 （主控制）、192.168.0.156、192.168.0.157）
2，IP：22這一臺做主控機器，另外2臺做客戶機。
3，提前在主控制機器上創建好公鑰，安裝好expect，使用腳本批量推送ssh公鑰。
4，本次部署是以root身份進行下面的操作。
二、正式部署
1，首先創建祕鑰
[root@Ansible .ssh]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
a3:08:ab:02:bf:7b:12:7d:d9:8f:9c:a9:67:38:53:a1 [email protected]
The key's randomart image is:
+--[ RSA 2048]----+
.
.. +S.
. .o..E.o.
.......+ =
..o . + B .
o o= .*
+-----------------+2，在根目錄下創建一個scripts來存放腳本文件和 ip.txt文件
[root@Ansible /]# mkdir scripts
[root@Ansible /]# cd scripts/
[root@Ansible scripts]# touch ip.txt3，接着在scripts目錄下編輯腳本文件及ip.txt內容：
[root@Ansible scripts]# cat fenfa.sh
#!/bin/bash
#date:2018-04-11
#author tony
#批量ssh認證建立
for p in $(cat /scripts/ip.txt)
do
ip=$(echo "$p"|cut -f1 -d":")
password=$(echo "$p"|cut -f2 -d":")
expect -c "
spawn ssh-copy-id -i /root/.ssh/id_rsa.pub root@$ip
expect {
\"*yes/no*\" {send \"yes\r\"; exp_continue}
\"*password*\" {send \"$password\r\"; exp_continue}
\"*Password*\" {send \"$password\r\";}
}
"
done
for h in $(cat /scripts/ip.txt|cut -f1 -d":")
do
ssh root@$h ' ifconfig '
#如果命令是多行的，請參照下面
#ssh root@$h '此處寫要執行的命令1'
#ssh root@$h '此處寫要執行的命令2'
#ssh root@$h '此處寫要執行的命令3'
done查看一下ip.txt
[root@Ansible scripts]# cat ip.txt
192.168.0.156:hwg123
192.168.0.157:hwg1234,最後執行腳本即可
[root@Ansible scripts]# sh fenfa.sh
spawn ssh-copy-id -i /root/.ssh/id_rsa.pub [email protected]
Now try logging into the machine, with "ssh '[email protected]'", and check in:
.ssh/authorized_keys
to make sure we haven't added extra keys that you weren't expecting.
