# Squidロギングオン

### 1. ForwardプロキシでSquidを使用する時、PLURA ロギング(logging)連動設定方法です。 <a href="#id-1" id="id-1"></a>

httpdと同様のロギング方法は下記の通りです。

{% hint style="info" %}

```
logformat httpd %>a %[ui %[un [%tl] “%rm %ru HTTP/%rv” %>Hs %<st “%{Referer}>h” “%{User-Agent}>h” %Ss:%Sh
access_log /var/log/squid/access.log httpd
```

{% endhint %}

### 2. jsonでPLURA V5ロギング形式で保存する方法は下記の通りです。 <a href="#id-2" id="id-2"></a>

`# vi /etc/squid/squid.conf`

{% hint style="info" %}

```
 forwarded_for on
 acl has-xff req_header X-Forwarded-For ^(([0-9]+\.[0-9]+\.[0-9]+\.[0-9]+)|(\[([0-9a-f]+)?:([0-9a-f:]+)?:([0-9a-f]+|0-9\.]+)?\]))

 # add logging for PLURA
 logformat combinedjson {“Remote-addr”: “%>a”, “X-forwarded-for”: “%{X-Forwarded-For}>h”, “Request-date”: “%tl”, “Method”: “%rm”, “Request”: “%rm %rp HTTP/%rv”, “Host”: “%>rd”, “Uri”: “%ru”, “Resp-Content-Type”: “%mt”, “Refere”: “%{Referer}>h”, “User-Agent”: “%{User-Agent}>h”, “Status”: “%>Hs”, “Resp-Content-Length”: “%<st”, “ProxyStatus”: “%Ss:%Sh”}

 #access_log /var/log/squid/access.log combinedjson
 access_log stdio:/var/log/plura/weblog.log combinedjson !has-xff
 access_log stdio:/var/log/plura/weblog.log combinedjson has-xff
```

{% endhint %}

### 3. Squidをウェブシステムとして認識させるコマンド <a href="#id-3" id="id-3"></a>

`# echo “ModPlura-squid” > /etc/modplura`

`# echo “0.0.1” >> /etc/modplura`

`# touch /etc/.modplura`

### 4. Squid accessログファイルに権限付与 <a href="#id-4" id="id-4"></a>

`# touch /var/log/plura/weblog.log`

`# chmod -R 766 /var/log/plura/weblog.log`

`# chcon -t squid_log_t /var/log/plura/weblog.log`

<br>

**PLURA > システム > システム管理**でリストのシステムを拡張すると、下記のように確認されます。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.plura.io/ja/faq/siem/logging/squid.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
