我正在尝试让 OrientDB 在 Ubuntu 16.04 LTS 上作为守护进程（启动时启用）运行。问题是，systemd 似乎在我告诉它启动后立即调用停止。我有这个 systemd 服务文件，完全符合 OrientDB 文档中的建议：

[Unit]
Description=OrientDB Server
After=network.target
After=syslog.target

[Install]
WantedBy=multi-user.target

[Service]
Type=forking
ExecStart=$ORIENTDB_HOME/bin/orientdb.sh start
ExecStop=$ORIENTDB_HOME/bin/orientdb.sh stop
ExecStatus=$ORIENTDB_HOME/bin/orientdb.sh status

orientdb.log：

           .

我对 OpenSuse Leap 42.1 和 OrientDB 2.2.7 也有同样的问题。罗伯托的回答解决了这个问题。请参阅GitHub 上的问题。

只要您将自定义初始化脚本（orientdb.sh 、server.sh、shutdown.sh）包装在 systemd 服务单元中，您就会遇到奇怪且难以调试的问题。

相反，您应该阅读这些脚本，了解它们如何启动 OrientDB 并仅在服务单元中重现必要的内容。

我在系统中添加了一个用户和组orientdb并在 systemd 脚本下使用（假设 orientdb 安装在/opt/orientdb 中）：

[Unit]
Description=OrientDB Server
After=network.target
After=syslog.target

[Install]
WantedBy=multi-user.target

[Service]
User=orientdb
Group=orientdb
ExecStart=/opt/orientdb/bin/server.sh
ExecStop=/opt/orientdb/bin/shutdown.sh
ExecReload=/bin/kill -HUP $MAINPID

如果您运行服务器并关闭窗口，服务器将被关闭。将它与 NOHUP (server.sh) 一起使用，如果关闭窗口，它将继续运行。

我也遇到了同样的问题，祝你好运
