卸载原有 openssl 版本

<span style="color: #57a64a;font-style: italic;line-height: 26px">#&nbsp;sudo&nbsp;apt-get&nbsp;remove&nbsp;openssl</span>

下载最新源码

<span style="color: #57a64a;font-style: italic;line-height: 26px">#&nbsp;sudo&nbsp;wget&nbsp;https://www.openssl.org/source/openssl-1.1.0f.tar.gz</span>

解压下载的源码

<span style="color: #57a64a;font-style: italic;line-height: 26px">#&nbsp;sudo&nbsp;tar&nbsp;-zxvf&nbsp;openssl-1.1.0f.tar.gz</span>

进入源码目录

<span style="color: #57a64a;font-style: italic;line-height: 26px">#&nbsp;sudo&nbsp;cd&nbsp;openssl-1.1.0f/</span>

配置

<span style="color: #57a64a;font-style: italic;line-height: 26px">#&nbsp;sudo&nbsp;./config&nbsp;shared&nbsp;--prefix=/usr/local/openssl&nbsp;--openssldir=/usr/lib/openssl</span>

编译并按照

<span style="color: #57a64a;font-style: italic;line-height: 26px">#&nbsp;sudo&nbsp;make&nbsp;&amp;&amp;&nbsp;make&nbsp;install</span>

设置环境变量

<span style="color: #57a64a;font-style: italic;line-height: 26px">#&nbsp;sudo&nbsp;vim&nbsp;~/.bashrc</span>

在最后一行添加<span style="color: #4ec9b0;line-height: 26px">export</span>&nbsp;PATH=<span style="color: #bd63c5;line-height: 26px">$PATH</span>:/usr/<span style="color: #4ec9b0;line-height: 26px">local</span>/openssl/bin&nbsp;保存退出

使上面的设置生效

<span style="color: #57a64a;font-style: italic;line-height: 26px">#&nbsp;sudo&nbsp;source&nbsp;~/.bashrc</span>

创建软连接

<span style="color: #57a64a;font-style: italic;line-height: 26px">#&nbsp;sudo&nbsp;ln&nbsp;-s&nbsp;/usr/local/openssl/lib/libssl.so.1.1&nbsp;/usr/lib/libssl.so.1.1</span>

<span style="color: #57a64a;font-style: italic;line-height: 26px">#&nbsp;sudo&nbsp;ln&nbsp;-s&nbsp;/usr/local/openssl/lib/libcrypto.so.1.1&nbsp;/usr/lib/libcrypto.so.1.1</span>

最后使用 openssl version 校验版本

<span style="color: #57a64a;font-style: italic;line-height: 26px">#&nbsp;openssl&nbsp;version</span>
