# rpm -qa | grep openssh openssh
# rpm -qa | grep openssh openssl
卸载用rpm -e 如果出现依赖包导致无法卸载,在最后面加上–nodeps即可,例:
# rpm -e openssl --nodeps
具体安装过程如下:
http://ftp5.usa.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-7.3p1.tar.gz
http://www.openssl.org/source/openssl-1.0.2j.tar.gz
http://www.openssl.org/source/openssl-fips-2.0.13.tar.gz
# yum install -y zlib-devel pam-devel tcp_wrappers-devel
具体说明见 http://www.openssl.org/docs/fips ;
# tar zxpf openssl-fips-2.0.5.tar.gz
# cd openssl-fips
# ./config
# make && make install
# tar zxpf openssl-1.0.1h.tar.gz
# cd openssl-1.0.1h
# ./config fips --shared
# make && make install
# echo "/usr/local/ssl/lib" >> /etc/ld.so.conf
# ldconfig
# tar zxpf openssh-6.6p1.tar.gz
# cd openssh-6.6p1
# ./configure \
--prefix=/usr \
--sysconfdir=/etc/ssh \
--with-md5-passwords \
--with-pam \
--with-tcp-wrappers \
--with-ssl-dir=/usr/local/ssl
# make && make install
# ssh -V
修改相关配置
# cp -p contrib/redhat/sshd.init /etc/init.d/sshd (此处的contrib路径为解压后的OpenSSH包路径)# chmod u+x /etc/init.d/sshd (加执行权限)# chkconfig --add sshd (增加sshd服务)# chkconfig sshd on (把sshd加入启动项)# yum install openssh (安装OpenSSH客户端)# vim /etc/ssh/sshd_configPermitRootLogin yes #允许root账户登录,单root账户必须加上,其他的参数请自行修改
# /etc/init.d/sshd start
