下面以CentOS平台为例,说明怎么安装ssh服务器。下面为了方便,都是以root用户权限去操作,实际情况下,请使用一般用户权限去使用,只需要加入sudo就行。
[root@localhost ~]# yum install openssh-server
这样就可以安装好ssh-server了。
检验SSH是否安装好了,可以用下面的命令:
[linuxidc@localhost ~]$ ssh -version
OpenSSH_5.3p1, OpenSSL 1.0.0-fips 29 Mar 2010
Bad escape character ‘rsion‘.
如果显示上面的信息,说明安装好了SSH。
有些用户可能会问,我怎么记地是安装openssh-server而不是直接yum install ssh呢?这里告诉大家一个方法(CentOS平台),可以快速知道我们需要安装程序的名称。如下:
[root@localhost ~]# yum search ssh
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
* base: mirrors.btte.net
* extras: mirrors.btte.net
* updates: www.ftp.ne.jp

从上面我们可以看到openssh-server,这就是我们需要安装的程序名称。
如果你是Ubuntu平台呢?没关系,可以运行下面的命令,也可以达到上面一样的效果
[root@localhost ~]# apt-get update //这行可以不要
[root@localhost ~]# apt-cache search ssh
下面我们列出ssh服务sshd在各个执行等级的启动情况:
[root@localhost ~]# chkconfig --list sshd
sshd 0:off 1:off 2:off 3:off 4:off 5:off 6:off
手动启动sshd服务(需要root权限),命令如下:
[root@localhost ~]# /etc/init.d/sshd start
Generating SSH1 RSA host key: [ OK ]
Generating SSH2 RSA host key: [ OK ]
Generating SSH2 DSA host key: [ OK ]
Starting sshd: [ OK ]
这样可以在putty或别的客户端登录到这台Linux机器了。如果需要停止ssh服务可以运行下面的命令
[root@localhost ~]# /etc/init.d/sshd stop
Stopping sshd: [ OK ]
