执行明令：
wget http://www.ctohome.com/linux-vps-pack/webmin/upgrade-openssh.sh
sh upgrade-openssh.sh
升级成功后会自动重启ssh服务，效果图如下：
Stopping sshd: [ OK ]
Starting sshd: [ OK ]

如果你发现还是ssh4.x版本，而且提示有错误： openssh-clients-5.8p1-24.el5.i386 from centalt has depsolving problems 那么，先需要安装libedit0类库，如下： centos 5.x 32位用如下命令安装 rpm -Uvh ftp://ftp.pbone.net/mirror/atrpms.net/el5-i386/atrpms/stable/libedit0-3.0-1.20090722cvs.el5.i386.rpm centos 5.x 64位用如下命令安装 rpm -Uvh ftp://ftp.pbone.net/mirror/atrpms.net/el5-x86_64/atrpms/stable/libedit0-3.0-1.20090722cvs.el5.x86_64.rpm 上面的两个包推荐使用迅雷下载！ 附件里的包是32位的系统用的 ，将文件的.jpg改成rpm然后上传到服务器中安装即可。 其他系统，请在这里找对应版本： http://rpm.pbone.net/index.php3/stat/3/srodzaj/1/search/libedit.so.0 如果你还是用的php5.1，也可以考虑这个脚本： 一键升级php5.2 wget http://www.CTOHome.com/linux-vps-pack/php5.2.sh
--> Missing Dependency: libedit.so.0 is needed by package openssh-clients-5.8p1-24.el5.i386 (centalt)
Error: Missing Dependency: libedit.so.0 is needed by package openssh-clients-5.8p1-24.el5.i386 (centalt)
You could try using --skip-broken to work around the problem
sh php5.2.sh
