I had the same issue after reinstalling nginx to newer version. Seems like log files ownership changed and new nginx couldn't save anything there. 

Removing log files and reloading nginx worked for me:

<pre><code>$ sudo rm -f /var/log/nginx/*
$ sudo nginx -s reload
</code></pre>

It looks like by default they are set to go to stdout and stderr. 

<pre><code>lrwxrwxrwx 1 root root 11 Apr 27 2016 access.log -&gt; /dev/stdout
lrwxrwxrwx 1 root root 11 Apr 27 2016 error.log -&gt; /dev/stderr
</code></pre>

So you can remove the symlinks and should be fine.

<pre><code>rm -f /var/log/nginx/*
</code></pre>

blocks|key|5976778|text|对于那些像我一样来到这里找出为什么日志文件是空的，并且没有意识到您实际上可能像另一个答案中的一个评论所建议的那样在docker容器中的所有人，只需打开一个新的shell并在日志后面加上|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5976779|docker+logs+{your-container-id-here}+-f|offset|length|style|CODE|5976780|entityMap^0|0|0|13|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@$D|L|E|M|F|G]]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

For all of those whose, like me, came here to figure out why the logs file are empty, and did not realise that you might actually be inside a docker container like one of the comments on another answer suggests, just open a new shell and tail the logs with 

<code>docker logs {your-container-id-here} -f</code>

By default Nginx image output the logs access/error to stdout/stderr.
<pre><code>lrwxrwxrwx 1 root root 11 Apr 27 2016 access.log -&gt; /dev/stdout
lrwxrwxrwx 1 root root 11 Apr 27 2016 error.log -&gt; /dev/stderr
</code></pre>
We can also check the same by visit this <a href="https://github.com/nginxinc/docker-nginx/blob/master/Dockerfile-alpine.template" rel="nofollow noreferrer">Nginx Dockerfile</a>, look for the comment # forward request and error logs to docker log collector
Now Use the below configuration in order to view the files.
I have changed file name
*error.log = error.logs
access.log = access.logs*
<pre><code>error_log /var/log/nginx/error.logs notice;
access_log /var/log/nginx/access.logs;

Your answer is <a href="http://techies-world.com/configure-nginx-to-send-logs-to-rsyslog/" rel="nofollow noreferrer">here</a>
Step1: Open the rsyslog config file
<pre><code>#vi /etc/rsyslog.conf
</code></pre>
Step2: Add the following line before the line <code>$IncludeConfig /etc/rsyslog.d/*.conf</code>
<pre><code>$ModLoad imfile
</code></pre>
Step3: Create a new file for nginx rsyslog configuration
<pre><code>#vi /etc/rsyslog.d/nginx.conf
</code></pre>
Step4: Update the following lines.
<pre><code># error log
$InputFileName /var/log/nginx/error.log
$InputFileTag nginx:
$InputFileStateFile stat-nginx-error
$InputFileSeverity error
$InputFileFacility local6
$InputFilePollInterval 1
$InputRunFileMonitor

# access log
$InputFileName /var/log/nginx/access.log
$InputFileTag nginx:
$InputFileStateFile stat-nginx-access
$InputFileSeverity notice
$InputFileFacility local6
$InputFilePollInterval 1
$InputRunFileMonitor
</code></pre>
Step5: Restart rsyslog service
<pre><code>#service rsyslog restart
</code></pre>

I have just installed nginx on Ubuntu 14.04 using the command

<pre><code>sudo apt-get install nginx
</code></pre>

Now, when I open my browser and type in the address <code>localhost</code> then I am correctly shown the "Welcome to nginx" page. Also, I checked the config file located in <code>/etc/nginx/nginx.conf</code> and found the following log settings:

<pre><code>access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
</code></pre>

However, when I check these two files, both are empty. I have opened the <code>localhost</code> page multiple times but still the log files are empty. What might be wrong with my setup ?

nginx : access.log and error.log file empty
