前述
注意事项：
此文升级是基于9.3p1升级9.3p2（如是7.4升级9.3p2，可参考文章最后的参考文章）
备份openssh9.3p1的配置文件
[root@localhost ~]# mv /usr/sbin/sshd /usr/sbin/sshd-9.3p1
[root@localhost ~]# mv /usr/bin/ssh /usr/bin/ssh-9.3p1
[root@localhost ~]# mv /usr/bin/ssh-keygen /usr/bin/ssh-keygen-9.3p1
[root@localhost ~]# mv /etc/init.d/sshd /etc/init.d/sshd-9.3p1
[root@localhost ~]# mv /etc/pam.d/sshd.pam /etc/pam.d/sshd.pam-9.3p1
下载 openssh9.3p2 的安装包：
或者是使用我提供的离线包：openssh7.4p1 升级到 openssh9.3p2 所需的离线包

wget https://cdn.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-9.3p2.tar.gz
解压并编译安装OpenSSH9.3p2
# 将下载的openssh安装包移动到/usr/local下
[root@localhost ~]# mv openssh-9.3p2.tar.gz /usr/local/
# 进入/usr/local/目录解压openssh9.3
[root@localhost ~]# cd /usr/local/
[root@localhost local]# tar xf openssh-9.3p2.tar.gz
# 进入openssh目录
[root@localhost local]# cd openssh-9.3p2
# 编译安装
[root@localhost openssh-9.3p2]# CCFLAGS="-I/usr/local/include" \
LDFLAGS="-L/usr/local/lib64" \
./configure \
--sysconfdir=/etc/ssh \
--with-zlib \
--with-ssl-dir=/usr/local/openssl
[root@localhost openssh-9.3p2]# make -j 4
[root@localhost openssh-9.3p2]# make install
授权
[root@localhost openssh-9.3p2]# chmod 600 /etc/ssh/*
复制配置文件
[root@localhost openssh-9.3p2]# cp -rf /usr/local/sbin/sshd /usr/sbin/sshd
[root@localhost openssh-9.3p2]# cp -rf /usr/local/bin/ssh /usr/bin/ssh
[root@localhost openssh-9.3p2]# cp -rf /usr/local/bin/ssh-keygen /usr/bin/ssh-keygen
[root@localhost openssh-9.3p2]# cp -ar /usr/local/openssh-9.3p2/contrib/redhat/sshd.init /etc/init.d/sshd
[root@localhost openssh-9.3p2]# cp -ar /usr/local/openssh-9.3p2/contrib/redhat/sshd.pam /etc/pam.d/sshd.pam
给sshd授予权限
chmod 755 /etc/init.d/sshd
启用sshd，生成服务配置文件，并重启服务
# 启用sshd，生成服务配置文件
[root@localhost openssh-9.3p2]# systemctl enable sshd
sshd.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig sshd on
# 重启服务
[root@localhost openssh-9.3p2]# systemctl restart sshd
# 查看服务状态
[root@localhost openssh-9.3p2]# systemctl status sshd
验证升级是否成功
[root@localhost ~]# ssh -V
OpenSSH_9.3p2, OpenSSL 1.1.1t 7 Feb 2023
