CentOS7升级openssl版本到1.0.2

wget http://www.openssl.org/source/openssl-1.0.2.tar.gz  

tar zxvf openssl-1.0.2.tar.gz  

cd openssl-1.0.2

./config  

make && make install

不指定安装路径，则安装在/usr/local/ssl中

mv /usr/bin/openssl /usr/bin/openssl.old

mv /usr/include/openssl /usr/include/openssl.old

ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl  

ln -s /usr/local/ssl/include/openssl /usr/include/openssl  

echo "/usr/local/ssl/lib">>/etc/ld.so.conf  

ldconfig -v  

openssl version -a
