fedora27安装ssh

Fedora安装sshd

先确认是否已安装ssh服务：

[root@localhost ~]# rpm -qa | grep openssh-server

openssh-server-5.3p1-19.fc12.i686 （这行表示已安装）

若未安装ssh服务，可输入：

#yum install openssh-server

进行安装

2、修改配置文件

#vi /etc/ssh/sshd_config

Port 22 监听的端口号，默认是22，可以自定义。

Protocol 2 支持的协议，默认就好，不用修改

PermitRootLogin yes 是否允许root直接登录，最好设置为no

MMaxAuthTries 6 最大登录数，默认是6，建议设置为3，防止别人密码穷举。

To start the sshd daemon, type the following at a shell prompt:

ystemctl start sshd.service

To stop the running sshd daemon, use the following command:

ystemctl stop sshd.service

If you want the daemon to start automatically at the boot time, type:

ystemctl enable sshd.service

Refer to Chapter 7, Services and Daemons for more information on how to configure services in Fedora.
