1、下载文件并解压:

cd /data

mkdir openssh

http://www.zlib.net/zlib-1.2.11.tar.gz

https://www.openssl.org/source/openssl-1.1.1g.tar.gz

https://cdn.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-8.2p1.tar.gz


tar --no-same-owner -zxf zlib-1.2.11.tar.gz

tar --no-same-owner -zxf openssl-1.1.1g.tar.gz

tar --no-same-owner -zxf openssh-8.2p1.tar.gz


2、安装更新:

yum -y update openssh

yum -y install wget tar gcc make


3、安装zlib:

cd zlib-1.2.11

./configure --prefix=/usr/local/zlib

make && make install


4、安装openssl:

cd ../

cd openssl-1.1.1g

./config --prefix=/usr/local/ssl -d shared

make && make install

echo '/usr/local/ssl/lib' >> /etc/ld.so.conf

ldconfig -v


5、安装openssh:

cd ../

cd openssh-8.2p1

./configure --prefix=/usr/local/openssh --with-zlib=/usr/local/zlib --with-ssl-dir=/usr/local/ssl

make && make install


6、移除以前安装的老版本:

yum remove openssh


7、更新配置信息

vim /usr/local/openssh/etc/sshd_config

添加:

8、复制并配置参数

cp  /data/openssh/openssh-8.2p1/contrib/redhat/sshd.init /etc/init.d/sshd

chkconfig --add sshd

cp /usr/local/openssh/etc/sshd_config /etc/ssh/sshd_config

cp /usr/local/openssh/sbin/sshd /usr/sbin/sshd

cp /usr/local/openssh/bin/ssh /usr/bin/ssh

cp /usr/local/openssh/bin/ssh-keygen /usr/bin/ssh-keygen

cp /usr/local/openssh/etc/ssh_host_ecdsa_key.pub /etc/ssh/ssh_host_ecdsa_key.pub
