centos6.5 openssh升级

1. 首先挂载CentOS6.5镜像mkdir/mnt/cdrommount/dev/cdrom /mnt/cdrom2. 修改repo文件Vi/etc/yum.repos.d/yum.repo[local]Name=localBaseurl=file:///mnt/cdrom/ServerEnabled=1Gpgcheck=03. Yum clean allYum 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 stopStopping sshd: [ OK ] [root@CentOS tmp]# rpm -qa opensshopenssh-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_649. 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
