编译某个软件的时候提示openssl版本过低，yum不给力，只要编译安装了。

系统：CentOS release 6.7 (Final)

自带openssl版本是：

OpenSSL 1.0.1e-fips 11 Feb 2013

openssl官网是：https://www.openssl.org

随便一个就行

wget https://www.openssl.org/source/openssl-1.0.2h.tar.gz
tar xf openssl-1.0.2h.tar.gz
mv openssl-1.0.2h /usr/local/openssl
cd /usr/local/openssl
./config shared zlib
make depned
make
make install

以前的openssl还在，先备份再替换

mv /usr/local/ssl/bin/openssl{,.back}
mv /usr/local/ssl/include/openssl{,.back}
mv /usr/bin/openssl{,.back}
mv /usr/lib64/openssl/engines{,.back}   //32bit是lib

ln -s /usr/local/openssl/apps/openssl /usr/local/ssl/bin/openssl
ln -s /usr/local/openssl/include/openssl /usr/local/ssl/include/openssl
ln -s /usr/local/openssl/engines /usr/lib64/openssl/engines
ln -s /usr/local/openssl/apps/openssl /usr/bin/openssl

ldconfig
