CentOS5.x下用YUM升级OpenSSH和OpenSSL
最近有些客户希望升级openssh和ssl，发现CentOS默认的库无法直接升级,可以下面的升级命令：
1.查看当前ssh的版本： [root@CentOS ~]# ssh -v OpenSSH_4.3p2, OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008
2.升级ssh： [root@CentOS ~]# wget http://www.ctohome.com/linux-vps-pack/webmin/upgrade-openssh.sh;sh upgrade-openssh.sh;
3.如果你发现还是ssh4.x版本，而且提示有错误： openssh-clients-5.5p1-24.el5.i386 from centalt has depsolving problems --> Missing Dependency: libedit.so.0 is needed by package openssh-clients-5.5p1-24.el5.i386 (centalt) Error: Missing Dependency: libedit.so.0 is needed by package openssh-clients-5.5p1-24.el5.i386 (centalt) You could try using --skip-broken to work around the problem
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
然后重新执行命令：
wget http://www.ctohome.com/linux-vps-pack/webmin/upgrade-openssh.sh;sh upgrade-openssh.sh;
附：升级php5.2
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;sh php5.2.sh;
