How can I change the location of ...log file location?

To change pm2's log file location, there are 2 solutions: define log path as parameter when pm2 command is executed (<code>-l</code>, <code>-o</code>, <code>-e</code>), or start pm2 from a configuration file.

For the parameter solution, here is an example:

<pre><code>pm2 start app.js -o ./out.log -e ./err.log
</code></pre>

If you don't want to define log path every time when pm2 is executed, you can generate a configuration file, define <code>error_file</code> and <code>out_file</code>, and start pm2 from that:

<ol>
<li>Generate a configuration file: <code>pm2 ecosystem simple</code>. This would generate a file <code>ecosystem.config.js</code>, with following content:

<pre><code>module.exports = {
 apps : [{
 name : "app1",
 script : "./app.js"
 }]
}
</code></pre></li>
<li>Define <code>error_file</code> (for error log) and <code>out_file</code> (for info log) in the file, such as:

<pre><code>module.exports = {
 apps : [{
 name : "app1",
 script : "./app.js",
 error_file : "./err.log",
 out_file : "./out.log"
 }]
}
</code></pre></li>
<li>Delete existing processes in pm2:

<pre><code>pm2 delete &lt;pid&gt;
</code></pre>

You can get pid by doing:

<pre><code>pm2 status
</code></pre></li>
<li>Start the process from the configuration file:

<pre><code>pm2 start ecosystem.config.js
</code></pre></li>
</ol>

In this way, the logs are saved to <code>./err.log</code> and <code>./out.log</code>.

Please refer to the <a href="http://pm2.keymetrics.io/docs/usage/application-declaration/#log-files" rel="noreferrer">document</a> for detail information.

Can I log the error and info in database instead of a log file?

I didn't find any resources in official document. It seems you need to write code and save log to database yourself.

blocks|key|25528|text|我只想在@shaochuancs中添加答案，在执行步骤3之前，请确保删除旧流程。如果不删除旧进程，则在启动应用程序后，您对进程文件所做的更改将不会生效。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|25529|在执行上面的步骤3之前，您需要发出此命令：|25530|pm2+delete+<pid>|code-block|syntax|javascript|25531|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|L|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|M|8|@]|9|@]|A|$G|H]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Just wanted to add to @shaochuancs answer, that before doing step 3, make sure you delete the old process. If you don't delete the old process, the changes that you made to your process file will not take into effect after you start your app. 

You will need to issue this command before doing step 3 above: 

<pre><code>pm2 delete &lt;pid&gt;
</code></pre>

In case you want pm2 on startup with changed logs path:

<ol>
<li>pm2 delete all</li>
<li>pm2 start ecosystem.js </li>
<li>pm2 save </li>
<li>pm2 startup </li>
</ol>

If you want to write both an error log and console log to the same file, might be a use case, like I am interested to have log in OneFile to push to ELK.you can use <code>-l</code>

<pre><code>-l --log [path] specify filepath to output both out and error logs
</code></pre>

Here is the example

<pre><code>pm2 start server.js -l /app/logs/server.log
</code></pre>

After doing changes do not forget to run this command as mentioned in the answer.

<pre><code>pm2 delete &lt;pid&gt;
</code></pre>

I have couple of questions regarding pm2

<ul>
<li>How can I change the location of <code>server-error-0.log</code> and
<code>server-out-0.log</code> files location from <code>c:\users\user\.pm2\logs</code> to other drive, due to restriction in server's c drive access.</li>
<li>Can I log the error and info in database instead of a log file? Do I need to write a separate module for that or is there any way to achieve this?</li>
</ul>

Pm2 changing log file location

日志文件

数据库

服务器

我有几个关于pm2的问题由于服务器的c驱动器访问限制，如何将server-error-0.log和server-out-0.log文件的位置从c:\users\user\.pm2\logs更改到其他驱动器。是否可以将错误和信息记录在数据库中，而不是日志文件中？我需要为此编写一个单独的模块吗?或者有什么方法可以实现这一点...
