centos系统编译openssl和openssl-lib的rpm安装包
由于漏洞原因需要升级系统的openssl版本到新的版本，但是openssl最新版本需要自己编译生成rpm安装文件，以下是编译步骤：
1、下载对应版本的源码包
可以去openssl github下载，https://github.com/openssl/openssl/releases，找到对应版本的tar.gz文件
2、安装相关依赖包
yum -y install curl which make gcc perl perl-WWW-Curl rpm-build zlib-devel
3、创建相应目录
mkdir -p /root/rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS}
4、创建spec的文件，以下spec的文件包含打包openssl-libs的rpm
cat << 'EOF' > /root/rpmbuild/SPECS/openssl.spec

EOF
如果不需要openssl-libs的rpm，仅仅只需要openssl的rpm，使用一下spec文件
cat << 'EOF' > /root/rpmbuild/SPECS/openssl.spec
Summary: OpenSSL 1.1.1w for Centos
Name: openssl
Version: %{?version}%{!?version:1.1.1w}

%make_installmkdir -p %{buildroot}%{_bindir}
mkdir -p %{buildroot}%{_libdir}
ln -sf %{openssldir}/lib/libssl.so.1.1 %{buildroot}%{_libdir}
ln -sf %{openssldir}/lib/libcrypto.so.1.1 %{buildroot}%{_libdir}
ln -sf %{openssldir}/bin/openssl %{buildroot}%{_bindir}%clean
[ "%{buildroot}" != "/" ] && %{__rm} -rf %{buildroot}%files
%{openssldir}
%defattr(-,root,root)
/usr/bin/openssl
/usr/lib64/libcrypto.so.1.1
/usr/lib64/libssl.so.1.1%files devel
%{openssldir}/include/*
%defattr(-,root,root)%post -p /sbin/ldconfig%postun -p /sbin/ldconfig
EOF
以上的spec文件里面有对应版本信息1.1.1w，需要根据自己的版本情况进行替换。
5、准备源码包，并编译rpm包
cp openssl-1.1.1w.tar.gz /root/rpmbuild/SOURCES
cd /root/rpmbuild/SPECS && \rpmbuild \-D "version 1.1.1w" \-ba openssl.spec
6、等待编译完成，完成之后，在/root/rpmbuild/RPMS/下面会有对应系统的编译包，我这里是x86_64的，进去之后可以看到rpm包
[root@hadoop-master x86_64]# ll
total 5804
-rw-r--r--. 1 root root 4134132 May 29 14:55 openssl-1.1.1w-1.el7.x86_64.rpm
-rw-r--r--. 1 root root 133000 May 29 14:55 openssl-debuginfo-1.1.1w-1.el7.x86_64.rpm
-rw-r--r--. 1 root root 234860 May 29 14:55 openssl-devel-1.1.1w-1.el7.x86_64.rpm
-rw-r--r--. 1 root root 1429624 May 29 14:55 openssl-libs-1.1.1w-1.el7.x86_64.rpm
7、升级安装openssl
rpm -ivh openssl-1.1.1w-1.el7.x86_64.rpm --nodeps --force
rpm -ivh openssl-libs-1.1.1w-1.el7.x86_64.rpm --nodeps --force
