解压
tar -zxvf zlib-1.3.1.tar.gz
tar -zxvf openssh-9.8p1.tar.gz
tar -zxvf openssl-3.2.1.tar.gz

备份
cp -rf /etc/ssh /etc/ssh.bak
cp -rf /usr/bin/openssl /usr/bin/openssl.bak
cp -rf /etc/pam.d /etc/pam.d.bak
cp -rf /usr/lib/systemd/system /system.bak

如有IPMI可用，可以不用安装telnet,否则建议安装telnet,防止失联

------------zlib
cd /usr/local/src/zlib-1.3.1

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

make -j 4 && make test && make install

----------------安装OpenSSL

cd /usr/local/src/openssl-3.2.1

./config --prefix=/usr/local/src/openssl

make -j 4 && make install

mv /usr/bin/openssl /usr/bin/oldopenssl
ln -s /usr/local/src/openssl/bin/openssl /usr/bin/openssl
ln -s /usr/local/src/openssl/lib64/libssl.so.3 /usr/lib64/libssl.so.3
ln -s /usr/local/src/openssl/lib64/libcrypto.so.3 /usr/lib64/libcrypto.so.3
#5.更新动态库
echo "/usr/local/src/openssl/lib64" >> /etc/ld.so.conf
ldconfig
#6.查看更新后的版本
openssl version -v

-------openssh
yum remove -y openssh
mv /etc/ssh /etc/ssh.20240702
rm -rf /etc/ssh/*

cd /usr/local/src/openssh-9.8p1/
./configure --prefix=/usr/local/src/ssh --sysconfdir=/etc/ssh --with-pam --with-ssl-dir=/usr/local/src/openssl --with-zlib=/usr/local/src/zlib
make -j 4 && make install

/usr/local/src/ssh/bin/ssh -V

cp -rf /usr/local/src/openssh-9.8p1/contrib/redhat/sshd.init /etc/init.d/sshd
cp -rf /usr/local/src/openssh-9.8p1/contrib/redhat/sshd.pam /etc/pam.d/sshd

cp -rf /usr/local/src/ssh/sbin/sshd /usr/sbin/sshd
cp -rf /usr/local/src/ssh/bin/ssh /usr/bin/ssh
cp -rf /usr/local/src/ssh/bin/ssh-keygen /usr/bin/ssh-keygen

echo 'PermitRootLogin yes' >> /etc/ssh/sshd_config
echo 'PasswordAuthentication yes' >> /etc/ssh/sshd_config

chkconfig --add sshd

ssh服务重启
/etc/init.d/sshd restart
