centos配置ssh已被广泛应用但是也在不断的更新，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。
在vmware安装一个CentOS的Sever版，终端里的内容不可滚动，不方便。在win下远程登录不错（win下有个Xshell）。默认安装ssh是有的。只是hosts访问问题。
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 ]
以上介绍CentOS配置ssh。
