# 下载openssl1.1
wget https://www.openssl.org/source/openssl-1.1.1.tar.gz

tar -xf openssl-1.1.1.tar.gz –C /usr/local/src
# 安装
cd /usr/local/src/openssl-1.1.1
./config --prefix=/usr/local/ssl -Wl,-rpath=/usr/local/ssl/lib
make
sudo make install
# 安装成功后，您可以在系统中查找OpenSSL
ls /usr/local/ssl/bin/

#配置环境变量让系统自动识别OpenSSL
sudo vi /etc/profile  or  sudo vi ~/.bashrc
export PATH=/usr/local/ssl/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/ssl/lib:$LD_LIBRARY_PATH
source /etc/profile   or  source ~/.bashrc
