SSH免密碼登入遠端電腦

YUM安裝SSH

$ yum -y install openssh

用ssh-keygen做出公用和私有鑰匙，並且設置無密碼連接，把master的id_rsa.pub傳給slave

$ ssh-keygen -t rsa -C root
Generating public/private dsa key pair.
Enter file in which to save the key (/home/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase): > /root/.ssh/authorized_keys
$ exit

再登入一次slave

$ ssh 192.168.1.29

已經不用再輸入密碼囉，這樣就完成了。
