確認

パッケージコマンドはwp package listで一覧表示ができます。

$ wp package list

追加できていますね。

使ってみる

とりあえずwp help doctorで何ができるかみてみます。

$ wp help doctor
NAME

  wp doctor

DESCRIPTION

  Diagnose what ails WordPress.

SYNOPSIS

  wp doctor <command>

SUBCOMMANDS

  check      Run a series of checks against WordPress to diagnose issues.
  list       List all available checks to run.

listで何がチェックできるかのリストが見れて、checkで実際にチェックができる様子です。

wp doctor list

とりあえず一覧表示してみます。
アップデートの確認や改ざんチェックなど、かなりいろいろなチェックができます。

$ wp doctor list

wp doctor check

ということで早速走らせてみます。
wp doctor checkの後ろにチェック項目を指定すると、その項目をチェックしてくれます。

コアのバージョンが最新版かを確認するwp doctor check core-update

wp doctor check core-updateを実行することで、WordPressのバージョンが最新版か確認できます。

$ wp doctor check core-update
+-------------+---------+-------------------------------------+
| name        | status  | message                             |
+-------------+---------+-------------------------------------+
| core-update | success | WordPress is at the latest version. |
+-------------+---------+-------------------------------------+

全てのテストを実行する

--allをつけることで、すべてのテストを一気に実行できます。

$ wp doctor check --all
Running checks  100% [==================================================================================================================] 0:03 / 0:02
+----------------------------+---------+--------------------------------------------------------------------+
| name                       | status  | message                                                            |
+----------------------------+---------+--------------------------------------------------------------------+
| core-verify-checksums      | success | WordPress verifies against its checksums.                          |

| constant-savequeries-falsy | success | Constant 'SAVEQUERIES' is undefined.                               |
| constant-wp-debug-falsy    | success | Constant 'WP_DEBUG' is defined falsy.                              |
| core-update                | success | WordPress is at the latest version.                                |

| option-blog-public         | success | Site is public as expected.                                        |
| plugin-active-count        | success | Number of active plugins (6) is less than threshold (80).          |
| plugin-deactivated         | warning | Greater than 40 percent of plugins are deactivated.                |
| plugin-update              | success | Plugins are up to date.                                            |
| theme-update               | success | Themes are up to date.                                             |

| language-update            | warning | 1 language has an update available.                                |
+----------------------------+---------+--------------------------------------------------------------------+

plugin-deactivatedとlanguage-updateが指摘されました。

language-updateはwp core language updateを実行することで解決できます。

$ wp core language update
$ wp doctor check language-update
+-----------------+---------+---------------------------+
| name            | status  | message                   |
+-----------------+---------+---------------------------+
| language-update | success | Languages are up to date. |
+-----------------+---------+---------------------------+

plugin-deactivatedについては、「使ってないプラグイン整理しろ」ということなので整理しましょう。

Tips

出力の変更

WP-CLIコマンドの出力は基本的に--format=jsonでJSON出力できることが多いです。

$ wp doctor check core-update --format=json  | jq .
[
  {
    "name": "core-update",
    "status": "success",
    "message": "WordPress is at the latest version."
  }
]

cronで監視することもできそうですし、AMIMOTO AMIのSSLドメインとかWordPress情報を収集するEC2 Systems Manger Documentを作ってみたの記事にあるように、EC2 Systems Managerと組み合わせることで外部からのモニタリングなども簡単にできそうです。
