如何升级openssl版本

查看当前openssl版本

openssl version
openssl version
openssl version

查看当前openssl安装位置

which openssl
which openssl
which openssl

下载openssl最新版本

wget https://www.openssl.org/source/openssl-1.1.1i.tar.gz
wget https://www.openssl.org/source/openssl-1.1.1i.tar.gz
wget https://www.openssl.org/source/openssl-1.1.1i.tar.gz

解压openssl

编译并安装openssl

cd openssl-1.1.1i
./config --prefix=/usr/local/openssl
make && make install
cd openssl-1.1.1i
./config --prefix=/usr/local/openssl
make && make install
cd openssl-1.1.1i
./config --prefix=/usr/local/openssl
make && make install

备份旧版openssl

mv /usr/bin/openssl /usr/bin/openssl.bak
mv /usr/bin/openssl /usr/bin/openssl.bak
mv /usr/bin/openssl /usr/bin/openssl.bak

建立软链接，使用新版openssl

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

更新动态链接库

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

重新加载动态链接库

ldconfig -v
ldconfig -v
ldconfig -v

查看当前版本
