1.hadoop安装好之后，执行ssh localhost无法执行，

提示“ssh: connect to host localhost port 22: Connection refused”。

2.ps -e |grep ssh查看后只有

“3748 ?        00:00:00 ssh-agent"

3.安装

sudo apt-get install openssh-server

4.启动sshd。

sudo /etc/init.d/ssh start

5.再次查看：

ps -e |grep ssh
3748 ? 00:00:00 ssh-agent
4085 ? 00:00:00 sshd

6.执行ssh localhost
