下载nginx源码

nginx 源码: https://github.com/nginx/nginx

编译运行Nginx

修改 /auto/cc/conf 文件，将ngx_compile_opt=“-c” 修改为 ngx_compile_opt=“-c -g”
执行 sudo ./auto/configure --prefix=nginx工程目录，如果遇到错误 “the HTTP rewrite module requires the PCRE library”，执行以下命令安装pcre和pcre
- brew install pcre
- brew install pcre2
执行 sudo make

执行 ./objs/nginx，打开浏览器访问下 127.0.0.1，没问题的话就可以看到Nginx的欢迎界面了。
但是在执行的时候启动失败：

处理方法：

按提示创建nggix/logs/error.log
退出nginx目录，使用 ./nginx/objs.nginx 启动

访问 http://127.0.0.1 打开页面如下：
