mkdir -p /root/soft cd /root/soft
一、下载安装包、解压、配置、安装 wget https://www.openssl.org/source/openssl-1.1.1i.tar.gz tar -zxvf openssl-1.1.1i.tar.gz cd openssl-1.1.1i ./config shared zlib
make make install
二、建立新的软连接及命令执行路径 mv /usr/bin/openssl /usr/bin/openssl.bak mv /usr/include/openssl /usr/include/openssl.bak ln -s /usr/local/bin/openssl /usr/bin/openssl ln -s /usr/local/include/openssl /usr/include/openssl echo "/usr/local/ssl/lib" >> /etc/ld.so.conf
三、解决：openssl: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory ln -s /usr/local/lib64/libssl.so.1.1 /usr/lib64/libssl.so.1.1 ln -s /usr/local/lib64/libcrypto.so.1.1 /usr/lib64/libcrypto.so.1.1
四、配置环境变量 echo "export LD_LIBRARY_PATH=/usr/local/lib:/usr/local/lib64" >>/etc/profile
五、加载配置 ldconfig -v
六、查看版本 openssl version
