一键升级openssh脚本

#!/bin/bash
tar -xzf openssh-9.3p2.tar.gz
tar -xzf openssl-1.1.1v.tar.gz
tar -xzf zlib-1.2.13.tar.gz
cd zlib-1.2.13
./configure --prefix=/usr/local/zlib
make && make install
echo '/usr/local/zlib/lib' >> /etc/ld.so.conf  
ldconfig -v
cd ../openssl-1.1.1t
./config --prefix=/usr/local/ssl -d shared
make && make install
echo '/usr/local/ssl/lib' >> /etc/ld.so.conf
ldconfig -v
cd ../openssh-9.3p2
./configure --prefix=/usr/local/openssh --with-zlib=/usr/local/zlib --with-ssl-dir=/usr/local/ssl
make && make install
echo 'PermitRootLogin yes' >>/usr/local/openssh/etc/sshd_config
echo 'PubkeyAuthentication yes' >>/usr/local/openssh/etc/sshd_config
echo 'PasswordAuthentication yes' >>/usr/local/openssh/etc/sshd_config
mv /etc/ssh/sshd_config /etc/ssh/sshd_config.bak
cp /usr/local/openssh/etc/sshd_config /etc/ssh/sshd_config
mv /usr/sbin/sshd /usr/sbin/sshd.bak
cp /usr/local/openssh/sbin/sshd /usr/sbin/sshd
mv /usr/bin/ssh /usr/bin/ssh.bak
cp /usr/local/openssh/bin/ssh /usr/bin/ssh
mv /usr/bin/ssh-keygen /usr/bin/ssh-keygen.bak
cp /usr/local/openssh/bin/ssh-keygen /usr/bin/ssh-keygen
mv /etc/ssh/ssh_host_ecdsa_key.pub /etc/ssh/ssh_host_ecdsa_key.pub.bak
cp /usr/local/openssh/etc/ssh_host_ecdsa_key.pub /etc/ssh/ssh_host_ecdsa_key.pub
cp -r contrib/redhat/sshd.init /etc/init.d/sshd
chmod +x /etc/init.d/sshd
chkconfig --add sshd
chkconfig sshd on
chmod 600 /etc/ssh/ssh_host_rsa_key
chmod 600 /etc/ssh/ssh_host_ecdsa_key
systemctl restart sshd
systemctl status sshd -l
ssh -V

后期升级更换版本脚本里面版本
