我配置了nginx。如下所示。但是,在运行客户端请求后,我在日志文件中仍然看不到任何内容。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,我调用了日志记录函数,如下所示。
ngx_log_debug0(NGX_LOG_INFO, r->connection->log, 0, "Calling ngx_http_hello_world_handler");
重启nginx服务器进程(sudo ../nginx-1.12.1-install/sbin/nginx),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

我看到了错误。日志文件包含如下,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
,但您只在http
部分启用了error_log ... debug
指令。但是根据文档,
error_log
可以放在这些上下文中:上下文:
main, http, mail, stream, server, location
我认为
NGX_LOG_INFO
是main
,所以尝试在http
之外的顶层添加error_log logs/error.log debug;
,如下所示:这也解释了为什么从
NGX_LOG_INFO
更改为NGX_LOG_DEBUG_HTTP
时会出现日志消息。kcrjzv8t2#
您可以尝试删除日志文件并重新启动nginx,以查看是否会创建新的日志文件。我在nginx文件夹中启动,可能路径不正确。nginx可能会在当前文件夹中找到,而不是nginx文件夹。也许有用

我通过修改日志参数使日志消息工作,如下所示。
我从NGX_LOG_INFO更改为NGX_LOG_DEBUG_HTTP。我不知道这些组件是什么,但我需要工作和理解的东西。
现在,我将在所有应用程序代码中继续使用相同的日志消息。

好吧,虽然这个问题已经发布很久了,我想澄清一下发生了什么,并详细说明一下@AnilJ为解决这个问题所做的工作。我先带你去看
ngx_log.h
头文件:前8个宏是从最高优先级到最低的主日志级别。而第二个堆栈是调试日志级别。如你所见
因此,以下措施应发挥作用:
为了验证这一点,我们可以看到这里的逻辑:
如果你在源代码中进一步研究,我们可以看到如果我们将日志级别设置为
debug
,则会设置以下内容:其中
NGX_LOG_DEBUG_ALL
等于0x 7 ffffff 0返回到问题中的问题,调用以下代码:
由于
r->connection->log=NGX_LOG_DEBUG_ALL=0x7ffffff0
和NGX_LOG_INFO=8
,而且您不会看到任何调试日志。要使它工作,应该选择
NGX_LOG_DEBUG_CORE,NGX_LOG_DEBUG_ALLOC,NGX_LOG_DEBUG_MUTEX,NGX_LOG_DEBUG_EVENT,NGX_LOG_DEBUG_MAIL,NGX_LOG_DEBUG_STREAM
或NGX_LOG_DEBUG_ALL
本身之一。
