What's？
タイトル通り。Amazon Linux 2に、GitBucketをsystemdのユニットとして登録して使いたい、ということで。
基本的な手順はこちらのWikiを参照します。
環境
今回の環境は、こちらです。
$ cat /etc/os-release
NAME="Amazon Linux"
VERSION="2"
ID="amzn"
ID_LIKE="centos rhel fedora"
VERSION_ID="2"
PRETTY_NAME="Amazon Linux 2"
ANSI_COLOR="0;33"
CPE_NAME="cpe:2.3:o:amazon:amazon_linux:2"
HOME_URL="https://amazonlinux.com/"
$ uname -srvmpio
Linux 4.14.256-197.484.amzn2.x86_64 #1 SMP Tue Nov 30 00:17:50 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
Java 8をインストールする
GitBucketは、Java 8で動作します。
GitBucket requires Java8. You have to install it, if it is not already installed.
Amazon Linux 2での選択肢はyumでインストールできるものか
$ yum search java-1.8.0-openjdk
読み込んだプラグイン:langpacks, priorities, update-motd

amazon-linux-extrasでインストールするAmazon Correttoなのですが。
$ amazon-linux-extras list | grep corretto -A 2
27 corretto8 available \
[ =1.8.0_192 =1.8.0_202 =1.8.0_212 =1.8.0_222 =1.8.0_232
=1.8.0_242 =stable ]
今回は、Amazon Correttoを使うことにしました。
$ sudo amazon-linux-extras install corretto8
バージョン。
$ java -version
openjdk version "1.8.0_312"
OpenJDK Runtime Environment Corretto-8.312.07.2 (build 1.8.0_312-b07)
OpenJDK 64-Bit Server VM Corretto-8.312.07.2 (build 25.312-b07, mixed mode)
余談ですが、11以降のAmazon Correttoはyumでインストールできるようです。
$ yum search corretto

GitBucketをインストールして、systemdのユニットとして登録する
では、こちらを参照しながらGitBucketをインストールして、systemdのユニットとして登録します。
GitBucketのインストール先は、/opt/gitbucketとします。
$ sudo mkdir /opt/gitbucket
$ cd /opt/gitbucket
グループおよびユーザーを作成。ログイン不可のユーザーですが、ホームディレクトリは/opt/gitbucketに調整。
$ sudo groupadd -g 555 gitbucket
$ sudo useradd \
-g gitbucket --no-user-group \
--home-dir /opt/gitbucket --no-create-home \
--shell /usr/sbin/nologin \
--system --uid 555 gitbucket
GitBucketのダウンロード。
$ sudo curl -LO https://github.com/gitbucket/gitbucket/releases/download/4.37.2/gitbucket.war
/opt/gitbucketの所有者を変更します。
$ sudo chown -R gitbucket:gitbucket /opt/gitbucket
systemdのユニット定義ファイルを作成。
/etc/systemd/system/gitbucket.service
[Unit]
Description=GitBucket is a Git web platform powered by Scala offering

daemon-reloadして、自動起動の設定も行います。
$ sudo systemctl daemon-reload
$ sudo systemctl enable gitbucket.service
起動。
$ sudo systemctl start gitbucket.service
statusで確認。
$ sudo systemctl status gitbucket.service

ログはこちらで参照。
$ sudo journalctl -u gitbucket.service -f
http://[GitBucketが動作しているホスト]:8080にアクセス。
ユーザーID、パスワードは共にrootです。
これで、GitBucketをsystemdのユニットとして登録しつつ、利用できます。
