SSH靜默模式

遠程自動生成ssh key

# 安裝自動輸入密碼 sshpass
yum -y install sshpass
# 遠程靜默安裝 ssh-key 
sshpass -p root  ssh root@10.10.0.5 "ssh-keygen -t rsa -N '' -f /root/.ssh/id_rsa -q"
# 遠程同步公鑰到公鑰集中服務器
mkdir  -p  /root/.ssh/pubs
sshpass -p root scp root@10.10.0.5:/root/.ssh/id_rsa.pub /root/.ssh/pubs/
cat id_rsa.pub >> /root/.ssh/authorized_keys
# 公鑰分發
sshpass -p root scp /root/.ssh/authorized_keys root@10.10.0.5:/root/.ssh/authorized_keys
