Linux通过expect配置自动登录

在home目录下创建.expect目录，并添加两个文件： expect登陆脚本ssh-login.exp #!/usr/bin/expect -fset timeout 30set host [

在home目录下创建.expect目录，并添加两个文件：

1. expect登陆脚本ssh-login.exp

#!/usr/bin/expect -fset timeout 30set host [lindex $argv 0]set port [lindex $argv 1]set user [lindex $argv 2]set password [lindex $argv 3]spawn ssh -p $port $user@$hostexpect {    "yes/no" { send "yes/r"; exp_continue }    "password:" { send "$password/r" }}interact

1. expect配置脚本ssh-login.sh

# alias ssh-name="./expect/ssh-login.exp host port username password"alias ssh-n1.cluster=".expect/ssh-login.exp 192.168.9.181 22 root cluster"alias ssh-n2.cluster=".expect/ssh-login.exp 192.168.9.182 22 root cluster"alias ssh-n3.cluster=".expect/ssh-login.exp 192.168.9.183 22 root cluster"alias ssh-n4.cluster=".expect/ssh-login.exp 192.168.9.184 22 root cluster"alias ssh-n5.cluster=".expect/ssh-login.exp 192.168.9.185 22 root cluster"

在.bashrc下添加

if [ -f ~/.expect/ssh-login.sh ]; then    . ~/.expect/ssh-login.shfi
