我已将nginx.conf配置为进行日志记录,如下所示 . 但是,在运行客户端请求后,我仍然没有在我的日志文件中看到任何内容 . 我刚开始学习nginx模块开发 .
#user nobody;
worker_processes 1;
pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
error_log logs/error.log debug;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log logs/access.log combined;
sendfile on;
#tcp_nopush on;
在其中一个模块代码中,我调用了日志功能,如下所示 .
ngx_log_debug0(NGX_LOG_INFO, r->connection->log, 0, "Calling ngx_http_hello_world_handler");
在我重新启动nginx服务器进程(sudo ../nginx-1.12.1-install/sbin/nginx)之后,我使用以下命令执行HTTP GET:
wget http://localhost/test
--2017-09-05 19:28:30-- http://localhost/test
Resolving localhost... ::1, 127.0.0.1

我看到error.log文件包含如下,但我打印的日志没有出来 .

有人能告诉我我错过了什么吗?

这可能是因为您登录到
NGX_LOG_INFO, r->connection->log
,但是您只在http
部分启用了error_log ... debug
指令 .但是根据docs,
error_log
可以放在这些上下文中:我认为
NGX_LOG_INFO
是main
,所以尝试在http
之外的顶级添加error_log logs/error.log debug;
,如下所示:这也解释了当您从
NGX_LOG_INFO
更改为NGX_LOG_DEBUG_HTTP
时出现日志消息的原因 .您可以尝试删除日志文件并重新启动nginx以查看是否将创建新的日志文件 . 我在nginx文件夹中启动它,可能路径不正确 . nginx可能在当前文件夹中找不到nginx文件夹 . 也许它很有用
我通过修改日志参数得到了我的日志消息,如下所示 .
我从NGX_LOG_INFO更改为NGX_LOG_DEBUG_HTTP . 我不确定这些组件是什么,但我需要工作和理解 .
现在,我将继续在我的所有应用程序代码中使用相同的日志消息 .
