前言

这一系列文章主要包含的内容主要是 各种常用软件的调试环境的搭建  

主要的目的是 搭建一个可打断点的一个调试环境 

c 系列 主要是基于 clion 调试, java 系列主要是基于 idea 调试, js 系列主要是基于 webstorm 调试 

需要有一定的 c, c++, java, js 相关基础 

基于的环境是一个 ubuntu16.04 desktop, 初始的时候 仅仅更新了源, 安装了 clion 
 

redis, nginx, mysql, vsftpd
javac, javap, jstack, jmap, jinfo
kafka,
spark, flink
coreutils, glibc, gdb 
hotspotVM, linux
... 等等其他

 

 

编译 nginx-1.22.1 

首先去官方网站下载最新源码, 然后拷贝自 目标虚拟机 

 

 

 

开始配置, 有条件的话可以安装一下 pcre, ssl, zip 相关库, 这里没有安装

开始编译 

调整编译时优化级别, 不优化

make -f objs/Makefile

clion 中调试

clion 中打开 nginx-1.22.1 项目 

新建 make application, 配置名称 

target 配置 make 相关, build 配置 Makefile 中 build 的命令, clean 配置 Makefile 中 clean 的命令 

executable 配置编译好的 nginx-server 的可执行文件 

program arguments 即为 nginx-server 所需要的参数, 这里配置为配置文件  

 

然后启动 nginx-server 服务 

 

 

访问 nginx 的服务

 

 

但是 还存在一个问题是, 我们期望调试的是请求流程的处理, 因此 我们需要调试 work 进程     

因此 我们这里交换 master, worker 的业务, 以便于 我们直接在 clion 中调试 worker 

 

 

ngx_http_static_module.ngx_http_static_handler 中打上断点, 然后 访问 nginx 的静态资源, 发现断点如下, 至此 可以正常调试了
