[系统运维]centos环境提示「openssl/ssl.h: No such file or directory」解决方法

问题描述

在docker镜像（centos系统）中，编译代码时，有如下错误

fatal error: openssl/ssl.h: No such file or directory
#include <openssl/ssl.h>                   // SSL_*

解决方法

找不到 openssl/ssl.h 头文件是因为 openssl-devel 缺失导致的，安装该库即可，可用如下命令：
sudo yum install -y openssl-devel

• 安装完成后，可以通过 sudo yum list installed | grep openssl-devel 查看是否安装成功。
• 安装前可以通过sudo yum info openssl-devel 查看源中对应的版本

openssl-devel安装过程中报错

使用『sudo yum install openssl-devel -y』安装openssl-dev过程中有相关依赖包安装失败，如下

 You could try using --skip-broken to work around the problem

解决方法：

• 切换源，以下切换为aliyun源，相关命令为：

sudo curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
sudo yum clean all
sudo yum makecache
sudo yum install -y openssl-devel

参考

• centos7 yum 切换成阿里源
