Linuxサーバーにセキュリティパッチを適用するためのプレイブックを作成し、パッチされたサーバーを再起動するための作業だけを作成した場合は残りました。
パッチの適用作業内容は次のとおりです。
- name: Deploying Security Packages
shell: "yum update --security -y"
register: progress
when: deploypackages == "y"
- name: Installed Packages
debug:
msg: "{{ progress.stdout_lines | regex_search('complete') }}"
#when: progress.changed | regex_search('complete')
出力で登録されている変数の単語を見つけて（存在する場合）、サーバーを再起動するcompletedフィルタを探しています。kernel
ありがとう
試み1 - 失敗
kernelテスト目的に変更しましたが、xz-libs条件に達すると失敗しますwhen。

新しいカーネルをインストールした後だけでなく、マイクロコード、glibc、SSLライブラリなどを更新した後でも再起動が必要になることがあります。したがって、まだ再起動して確認する必要があるいくつかのイベントがあります。
RHELには、利用可能な基本オペレーティングシステムパッケージマネージャに基づくいくつかのユーティリティがあります。これには、更新を適用した後にこれが必要かどうかを問い合わせるスクリプトyum-utilsなどが含まれます。needs-restarting
はい(RHEL 7基準)
依存関係を解決した後
- name: Install basic admin tools
yum:
name: yum-utils
state: latest
確認は簡単です
- name: Check if reboot_required
shell:
cmd: "needs-restarting -r"
changed_when: false
failed_when: reboot_required.rc != 0 and reboot_required.rc != 1
check_mode: false
register: reboot_required
- name: Report reboot_required
debug:
msg: "{{ reboot_required.rc | bool }} "
changed_when: reboot_required.rc == 1
check_mode: false
そして出力を生成
TASK [Report reboot_required] **************************************************
ok: [test1.example.com] => {
"msg": "True "
}
ok: [test2.example.com] => {
"msg": "False "
}
再起動が必要かどうかを確認するパッケージは、他のディストリビューションでも使用できます。

また、インフラストラクチャや環境に応じて、cronjobを介してシステムを完全に自動的に再起動することも可能です。
