快速生成ssh-keygen免密登录脚本

reio

脚本可快速为用户生成ssh免密的keygen，建议扔到服务器的/etc/profile.d/目录
Cshell模式

1. #!/bin/csh
   
2. if ( ! -e ~/.ssh/id_rsa ) then
   
3.        mkdir -p ~/.ssh
   
4.        chmod 700 ~/.ssh
   
5.        ssh-keygen -t rsa -f ~/.ssh/id_rsa -N "" >/dev/null
   
6.        cp ~/.ssh/id_rsa.pub ~/.ssh/authorized_keys
   
7.        echo "Host * ">~/.ssh/config
   
8.        echo "StrictHostKeyChecking no">>~/.ssh/config
   
9.        chmod 644 ~/.ssh/config
