Ubuntu 升级 openssl 的方案

首先要准备编译包，肯定是去官网下载了：[https://www.openssl.org/source/][https_www.openssl.org_source]，我下载的是 openssl-1.1.0g.tar.gz 这个版本。  
解压并且进入此目录。

tar -zxvf openssl-1.1.0g.tar.gz cd openssl-1.1.0g

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> <p>2</p> </td> 
   <td> <p>tar -zxvf openssl-1.1.0g.tar.gz</p> <p>cd openssl-1.1.0g</p> </td> 
  </tr> 
 </tbody> 
</table>

下面就是操作的流程了：

1. 备份旧的openssl。

mv /usr/bin/openssl /usr/bin/openssl.old mv /usr/include/openssl /usr/include/openssl.old mv /usr/local/openssl /usr/local/openssl.old

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> <p>2</p> <p>3</p> </td> 
   <td> <p>mv /usr/bin/openssl /usr/bin/openssl.old</p> <p>mv /usr/include/openssl /usr/include/openssl.old</p> <p>mv /usr/local/openssl /usr/local/openssl.old</p> </td> 
  </tr> 
 </tbody> 
</table>

2. 进入目录并编译:

cd openssl-1.1.0g ./config --prefix=/usr/local/ssl shared zlib make depend make && make install

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> <p>2</p> <p>3</p> <p>4</p> </td> 
   <td> <p>cd openssl-1.1.0g</p> <p>./config --prefix=/usr/local/ssl shared zlib</p> <p>make depend</p> <p>make &amp;&amp; make install</p> </td> 
  </tr> 
 </tbody> 
</table>

3.将软链接添加上:

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

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> <p>2</p> <p>3</p> </td> 
   <td> <p>ln -s /usr/local/ssl /usr/local/openssl</p> <p>ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl</p> <p>ln -s /usr/local/ssl/include/openssl /usr/include/openssl</p> </td> 
  </tr> 
 </tbody> 
</table>

执行 openssl version 还是报错了:  
错误如下:

openssl: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> </td> 
   <td> <p>openssl: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory</p> </td> 
  </tr> 
 </tbody> 
</table>

这是由于openssl库的位置不正确造成的。  
解决方法:

ln -s /usr/local/openssl/lib/libssl.so.1.1 /usr/lib/libssl.so.1.1

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> </td> 
   <td> <p>ln -s /usr/local/openssl/lib/libssl.so.1.1 /usr/lib/libssl.so.1.1</p> </td> 
  </tr> 
 </tbody> 
</table>

再执行 openssl version 还报错:

openssl: error while loading shared libraries: libcrypto.so.1.1: cannot open shared object file: No such file or directory

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> </td> 
   <td> <p>openssl: error while loading shared libraries: libcrypto.so.1.1: cannot open shared object file: No such file or directory</p> </td> 
  </tr> 
 </tbody> 
</table>

解决方法:

ln -s /usr/local/openssl/lib/libcrypto.so.1.1 /usr/lib/libcrypto.so.1.1

<table> 
 <tbody> 
  <tr> 
   <td> <p>1</p> </td> 
   <td> <p>ln -s /usr/local/openssl/lib/libcrypto.so.1.1 /usr/lib/libcrypto.so.1.1</p> </td> 
  </tr> 
 </tbody> 
</table>
