1.解压安装包
tar zxvf openssl-1.1.1t.tar.gz -C /usr/local/src/
tar zxvf openssh-9.7p1.tar.gz -C /usr/local/src/
tar zxvf zlib-1.2.13.tar.gz -C /usr/local/src/
2.安装zlib
cd /usr/local/src/
cd zlib-1.2.13/
./configure --prefix=/usr/local/zlib && make -j 4 && make install
3.安装openssl
cd /usr/local/src/openssl-1.1.1t/
./config --prefix=/usr/local/ssl -d shared
make -j 4 && make install
echo '/usr/local/ssl/lib' >> /etc/ld.so.conf
ldconfig -v
4.安装opnessh
mv /etc/ssh /etc/ssh.bak
cd /usr/local/src/openssh-9.7p1/
./configure --prefix=/usr/local/openssh --sysconfdir=/etc/ssh --with-ssl-dir=/usr/local/ssl --with-zlib=/usr/local/zlib
make -j 4 && make install
5.修改配置文件
echo "X11Forwarding yes" >> /etc/ssh/sshd_config
echo "X11UseLocalhost no" >> /etc/ssh/sshd_config
echo "XAuthLocation /usr/bin/xauth" >> /etc/ssh/sshd_config
echo "UseDNS no" >> /etc/ssh/sshd_config
echo 'PermitRootLogin yes' >> /etc/ssh/sshd_config
echo 'PubkeyAuthentication yes' >> /etc/ssh/sshd_config
echo 'PasswordAuthentication yes' >> /etc/ssh/sshd_config
6.备份原来的配置文件
mv /usr/sbin/sshd /usr/sbin/sshd.bak
cp -rf /usr/local/openssh/sbin/sshd /usr/sbin/sshd
mv /usr/bin/ssh /usr/bin/ssh.bak
cp -rf /usr/local/openssh/bin/ssh /usr/bin/ssh
mv /usr/bin/ssh-keygen /usr/bin/ssh-keygen.bak
cp -rf /usr/local/openssh/bin/ssh-keygen /usr/bin/ssh-keygen
7.设置开机自启动
systemctl enable sshd
systemctl restart sshd
8.再次设置开启自启动
systemctl enable sshd
