源码编译安装openssh 最新版

# 创建几个目录备用

mkdir -p /usr/local/zlib/
mkdir -p /usr/local/openssl/
mkdir -p /usr/local/openssh/

# 安装编译需要用到的依赖包

yum -y install wget dnf vim gcc gcc-c++ make perl pam-devel

# 下载相关源码包

cd /root
wget https://ftp.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-9.3p1.tar.gz --no-check-certificate &&
wget http://www.zlib.net/zlib-1.2.13.tar.gz &&
wget https://www.openssl.org/source/openssl-1.1.1t.tar.gz --no-check-certificate

# 解压源码包

tar -zxvf openssl-1.1.1t.tar.gz &&
tar -zxvf openssh-9.3p1.tar.gz &&
tar -zxvf zlib-1.2.13.tar.gz
