/etc/systemd/system/mariadb.service で mariadb のサービスを定義しました。
[Unit]
Description=start and stop MySQL(MariaDB) Server
After=syslog.target
After=network.target
[Service]
Type=simple
User=Umariadb
Group=Gmariadb
# Restart=always
# PermissionsStartOnly=true
ExecStart=/usr/local/ServerWeb/mariadb/bin/mysqld_safe --user=mysql --ledir=/usr/local/ServerWeb/mariadb/bin --datadir=/usr/local/ServerWeb/mariadb/data
# ExecStop=/usr/bin/vgaoff stop
TimeoutSec=300
PrivateTmp=true
[Install]
WantedBy=multi-user.target
後で有効にしました。
systemctl enable mariadb.service
今再起動した後、サービスは起動しない。
その後、サービスを再度無効にする必要があります。
手動でやり直してみるとうまくいきました...
sudo /usr/local/ServerWeb/mariadb/bin/mysqld_safe --user=mysql --ledir=/usr/local/ServerWeb/mariadb/bin --datadir=/usr/local/ServerWeb/mariadb/data
私のサービススクリプトはよく定義されていますか？
何が問題なのか知りたいです。どうやって解決しますか？

答え1
使用しないでくださいmysqld_safe。
あらゆる種類の問題に直面することになりますが、最終的に問題は競争相手を構築し、この分野での地位を占めることに関連しています。システム化された恐怖の家Service Managerの下で、Poor Man's Dæmon Supervisor（シェルスクリプトで正しく作成されていません）を実行します。より良い相互運用性のために厳しくチェックし、調整し、準備プロトコルの不一致を処理し、異なる2つの場所で異なる方法で設定する衝突で終わることができますが、実際には意味がありません。代わりにdaemontoolsの世界で学びなさい。mysqld_safe 消えた世紀の転換期から。
数年が過ぎると、システムの世界から抜け出すことができます。 OracleとMySQLの世界とは異なり、MariaDBの世界の1つの違いは、サービスをサービスmysqld_safeとして使用するのではなく、daemontools/runit/s6ユーザーが長年にわたって望んでいた方法でMariaDBを実行する方法に関する良いドキュメントが実際にあることです。管理のためのツールセット。
マリアデータベース付属mariadb.servicesystemd のサービス単位および設定を systemd サービス単位設定にmariadb-service-convert移行するツールです。ユーザーが複数のサーバーを異なるサービスとして実行できるサービス単位テンプレートmy.cnfも付属しています。[email protected]それらを使用してください。
