  yum install openssl openssl-devel -y

• Ubuntu安装

  apt install openssl libssl-dev -y

源码编译安装OpenSSL

Downloads Old Releases

1. 依赖安装

   • Centos安装

     yum install perl-IPC-Cmd zlib -y

   • Ubuntu安装

     暂未发现所需安装额外依赖

2. 下载源码包

   wget https://www.openssl.org/source/openssl-3.2.1.tar.gz --no-check-certificate

3. 解压

   tar -zxvf openssl-*.tar.gz && cd openssl-*

4. 配置编译项

   ./config --prefix=/usr/local/openssl --openssldir=/usr/local/openssl shared zlib

   指定静态库：-fPIC

5. 开始编译

   make & make install

   同时运行

   make -j 4 & make install

6. 移除旧版本

   mv /usr/bin/openssl /usr/bin/openssl.bak
   mv /usr/include/openssl/ /usr/include/openssl.bak

7. 创建软连接

   ln -s /usr/local/openssl/include/openssl /usr/include/openssl
   ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl
   ln -s /usr/local/openssl/lib/libssl.so.3 /usr/lib64/libssl.so.3
   ln -s /usr/local/openssl/lib/libcrypto.so.3 /usr/lib64/libcrypto.so.3

8. 添加到动态链接库

   echo "/usr/local/openssl/lib" >> /etc/ld.so.conf
   ldconfig

9. 验证

   openssl version
