1. 首先挂载CentOS6.5镜像
mkdir/mnt/cdrom
mount/dev/cdrom /mnt/cdrom
2. 修改repo文件
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. 卸载系统自带的openssh,卸载之前先停止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文件,解压,文件夹下打开console
./config --prefix=/usr/local/openssl && make && make install
7. 上传openssh文件,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. 修改配置文件
[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权限
不用再修改文件了
[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_6.6p1, OpenSSL 1.0.1e-fips 11 Feb 2013
