Nginx模块如何调试

编写nginx.conf，将nginx设置为单进程调试模式

worker_processes  1;

error_log  logs/error.log debug; #  记录调试日志 
master_process  off;             #  单进程模式
daemon          off;            

pid /tmp/nginx_debug.pid;
events {
    worker_connections  1024;
}
http {
    include       /etc/nginx/mime.types;
    sendfile        on;
    keepalive_timeout  65;
    tcp_nodelay        on;
    server {
        listen   80;
        server_name  localhost;
        access_log  /tmp/access.log;
        error_log  /tmp/error.log debug;
        location /hello {
            echo "helloworld";
        }
    }
}

为了方便使用调试器, 可以单进程非daemon方式启动, 使用参数:

daemon off;
master_process off;

编写模块ngx_module_echo
在ngx_module_echo
回到nginx的源码目录进行安装:

~/nginx-0.8.9/#./configure --add-module=/home/doyoueat/ngx_module_echo/ --with-debug
make
sudo make install

然后运行一下看看,先测一下配置文件的正确性:

~/nginx-0.8.9/#./objs/nginx -c /home/doyoueat/ngx_module_echo/nginx.conf -t
the configuration file /home/doyoueat/ngx_module_echo/nginx.conf syntax is ok
configuration file /home/doyoueat/ngx_module_echo/nginx.conf test is successful

运行之:

~/nginx-0.8.9/#./objs/nginx -c /home/renlu/ngx_module_echo/nginx.conf

在另一个终端执行一个curl:

~#curl http://127.0.0.1/hello
helloworld
