centos6.5 openssh 升级

1.      首先挂载 CentOS6.5 镜像站群
mkdir/mnt/cdrom
mount/dev/cdrom /mnt/cdrom
2.      修改 repo 档案
Vi/etc/yum.repos.d/yum.repo
[local]
Name=local
Baseurl=file:///mnt/cdrom/Server
Enabled=1
Gpgcheck=0
3.      Yum clean all
Yum install gcc*
 
4.      解除安装系统自带的 openssh，解除安装之前先停止 sshd 服务，再用 rpm 删除，同时清除系统/etc/ssh 目录
[root@CentOS tmp]# service sshd stop
Stopping sshd:                                            [  OK  ]
[root@CentOS tmp]# rpm -qa openssh
openssh-5.3p1-94.el6.x86_64
[root@CentOS tmp]# rpm -e –nodeps openssh-server
[root@CentOS tmp]# rpm -e –nodeps openssh-clients
[root@CentOS tmp]# rpm -e –nodeps openssh-askpass
[root@CentOS tmp]# rpm -e–nodeps openssh
[root@CentOS tmp]# rm -rf /etc/ssh
重启！！！
5.      上传 zlib，安装 zlib
[root@CentOS tmp]# tar -xvf zlib-1.2.8.tar.gz
[root@CentOS tmp]# cd zlib-1.2.8
[root@CentOS zlib-1.2.8]# ./configure –prefix=/usr/local/zlib &&make && make install
 
6.      上传 openssl 档案，解压，资料夹下开启 console
./config –prefix=/usr/local/openssl && make && make install
 
7.      上传 openssh 档案，解压，
./configure–prefix=/usr/ –sysconfdir=/etc/ssh –with-ssl-dir=/usr/local/openssl–with-zlib=/usr/local/zlib –with-md5-passwords –without-hardening &&make && make install
 
8.      修改配置档案
[root@CentOSopenssh-6.6p1]# cp contrib/redhat/sshd.init /etc/init.d/sshd
[root@CentOSopenssh-6.6p1]# chmod +x /etc/init.d/sshd 一般自带 x 许可权
不用再修改档案了
[root@CentOSopenssh-6.6p1]#rpm -qa openssh
openssh-5.3p1-122.el6.x86_64
9.      加入到系统服务
 
[root@CentOSopenssh-6.6p1]# chkconfig –add sshd
[root@CentOSopenssh-6.6p1]# service sshd start
 
10.   检查版本
ssh -V   注意大写
OpenSSH_5.3p1, OpenSSL 1.0.1e-fips 11 Feb 2013
