安装编译环境

yum -y install curl  which  make gcc perl  perl-WWW-Curl  rpm-build

mkdir -p /root/rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS}

cp openssl-1.1.1w.tar.gz /root/rpmbuild/SOURCES/

准备openssl.spec文件

openssl.spec文件注意这行，这里为openssl安装路径，后续openssh会使用到

%global openssldir /usr/local/openssl

cd /root/rpmbuild/SPECS
rpmbuild -ba openssl.spec

生成rpm包在

/root/rpmbuild/RPMS/x86_64

安装rpm包

rpm -ivh  openssl-1.1.1w-1.el7.x86_64.rpm openssl-devel-1.1.1w-1.el7.x86_64.rpm --force --nodeps
