[英]Bash script to push ssh_keys
I'm trying to read a file with the names of approx 500 server names on their own individual lines, and then for each of those, ssh in and append the roots authorized_keys
file for each. 我试图读取一个单独的行上带有大约500个服务器名称的文件,然后对其中的每个ssh输入ssh并为每个文件附加roots
authorized_keys
文件。 I keep getting errors each time I run the script and/or modify it. 每次运行脚本和/或修改脚本时,都会不断出现错误。 Can you please help me figure out what's wrong?
您能帮我找出问题所在吗? My OS is Mac OS X:
我的操作系统是Mac OS X:
#!/usr/bin/expect
set timeout 60
set SERVERS "cat /Users/macuser/server.lst"
set USER "myuser"
set MY_PASS "mypasswordhere"
for EACH in $SERVERS; do
cat /Users/macuser/.ssh/id_rsa.pub | ssh $USER@$EACH "tee -a .ssh/authorized_keys"
expect {
eof {break}
"The authenticity of host" {send "yes\r"}
"password:" {send "$MY_PASS\r"}
}
interact
done
here is the error: 这是错误:
wrong # args: should be "for start test next command"
while executing
"for EACH in $SERVERS"
(file "./keyssh_push.sh" line 7)
From Use expect in bash script to provide password to SSH command , sshpass
looks like the easiest way to do this. 从使用bash脚本中的
sshpass
为SSH命令提供密码中 , sshpass
看起来是最简单的方法。 I would do: 我会做:
#!/bin/sh
servers=`cat /Users/macuser/server.lst`
user="myuser"
my_pass="mypasswordhere"
for server in $servers
do
</Users/macuser/.ssh/id_rsa.pub sshpass -p"$my_pass" \
ssh -o StrictHostKeyChecking=no $user@$server cat '>>.ssh/authorized_keys'
done
With @alvits's suggestion: 随着@alvits的建议:
#!/bin/sh
servers=`cat /Users/macuser/server.lst`
user="myuser"
my_pass="mypasswordhere"
for server in $servers
do
sshpass -p"$my_pass" ssh-copy-id -o StrictHostKeyChecking=no \
-i /Users/macuser/.ssh/id_rsa $user@$server
done
