Linux升级openssl版本 1、下载最新版本wget https://www.openssl.org/source/openssl-1.1.1w.tar.gz2、解压并进入解压目录后执行：./config --prefix=/usr/local/openssl shared zlib make depend make && make install3、备份当前openssl：mv /usr/bin/openssl /usr/bin/openssl.bak mv /usr/local/openssl /usr/local/openssl.bak mv /usr/include/openssl /usr/include/openssl.bak mv /usr/local/openssl/bin/openssl /usr/local/openssl/bin/openssl.bak4、配置使用新版本：ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl ln -s /usr/local/openssl/include/openssl /usr/include/openssl5、更新动态链接库数据：echo “/usr/local/ssl/lib” >> /etc/ld.so.conf ldconfig -v6、重新查看版本号：openssl version结果报错了，这是由于openssl库的位置不正确造成的。可以做一个软连接：ln -s /usr/local/openssl/lib/libssl.so.1.1 /usr/lib/ ln -s /usr/local/openssl/lib/libcrypto.so.1.1 /usr/lib/然后再执行第5步再查看版本号openssl version转载自：https://blog.csdn.net/qq_41570012/article/details/125597119
