ブート後にmariadbサービスが開始されない、CentOS 7

/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

後で私はそれをアクティブにしました：

systemctl enable mariadb.service

ここで、再起動後、サービス開始されていませんです。

次に、サービスを再度無効にする必要があります。

もう一度手動で実行しようとすると、完全に機能します...

Sudo /usr/local/ServerWeb/mariadb/bin/mysqld_safe --user=mysql --ledir=/usr/local/ServerWeb/mariadb/bin --datadir=/usr/local/ServerWeb/mariadb/data

サービスのスクリプトは適切に定義されていますか？

何が問題なのか知りたいのですが、どうやって解決しますか？

_mysqld_safe_は使用しないでください。

あらゆる種類の問題があり、サービスの下で貧弱な人のデーモンスーパーバイザー（シェルスクリプトで正しく記述されていない）を実行して、systemd House of Horrorの場所の候補を構築するまですべての問題があります。管理。 2つの異なる場所で2つの異なる方法で物事を設定することになったレディネスプロトコルの不一致や競合に対処し、相互運用性を高めるために面倒な作業を行って調整することができますが、それは実際には無意味です。代わりに、世紀の変わり目から_mysqld_safe_goneを求めてきたdaemontoolsの世界から学んでください。

この数年後、systemdの世界でもそれを取り除くことができます。 MariaDBの世界は、OracleやMySQLの世界とは対照的に、daemontools/runit/s6のユーザーが_mysqld_safe_なしでこれらの年すべてを望んでいた方法でMariaDBを実行する方法について、実際に優れたdocoを提供するという特徴があります。代わりに、サービス管理用のサービス管理ツールセットを使用します。

MariaDBには、systemdの_mariadb.service_サービスユニット、および_mariadb-service-convert_からsystemdサービスユニット設定に設定を移行する_my.cnf_ツールが付属しています。また、_[email protected]_サービスユニットテンプレートが付属しているため、複数のサーバーを個別のサービスとして実行できます。それらを使用してください。

次に、ソケットの場所を変更する設定ファイル/ etc/my.cnfを変更し、その場所の所有権（それぞれのuser：groupへの）フォルダーを確認します...

[client]
...
socket      = /usr/local/ServerWeb/mariadb/tmp/mysql.sock
...

[mysqld]
...
socket      = /usr/local/ServerWeb/mariadb/tmp/mysql.sock
...

そして、ソケット用のフォルダtmpを作成し、所有権を再度確認しました！

Sudo mkdir -pv /usr/local/ServerWeb/mariadb/tmp
Sudo chown -R Umariadb:Gmariadb /usr/local/ServerWeb/mariadb/

この変更の後、CentOS 7を再起動します
