centos的ssh配置

默认情况是，CentOS的sshd服务是开启的，但是需要我们修改一下相关的配置文件。

这里介绍CentOS配置ssh安装设置使用，帮助大家安装更新CentOS配置ssh系统。绝大部分内容适用于CentOS /RHEL ，同时也适用于其他发行版本。

1.在hosts.deny文件尾添加CentOS配置ssh:ALL意思是拒绝所有访问请求

[root@localhost ~]# vi /etc/hosts.deny修改后看起来如下：
#hosts.denyThis file describes the names of the hyusaosts which are
#*not* allowed to use the local INET services, as decided
#by the '/usr/sbin/tcpd' server.
#The portmap line is redundant, but it is left to remind you that
#the new secure portmap uses hosts.deny and hosts.allow.  In particular
#you should know that NFS uses portmap!
sshd:ALL

2.在hosts.allow文件尾添加CentOS配置ssh:192.168.0.
意思是允许192.168.0.1 到254的主机，内网。
[root@localhost ~]# vi /etc/hosts.allow
#
# hosts.allow   This file describes the names of the hosts which are
#               allowed to use the local INET services, as decided
#               by the '/usr/sbin/tcpd' server.

sshd:192.168.0.

3.重启CentOS配置ssh
[root@localhost ~]# /etc/rc.d/init.d/sshd restart
停止 ssh  [  确定  ]
启动 ssh  [  确定  ]

这样，就可以远程登录主机，进行其它相关配置了。
