Question

我正在尝试让OrientDB在Ubuntu 16.04 LTS上作为守护进程运行（在启动时启用）。问题是，在我告诉它启动后，systemd似乎立即调用stop。我完全按照OrientDB文档中的建议使用此systemd服务文件：

[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：

有什么想法吗？

Answer 1

只要在系统服务单元中包装自定义初始化脚本（orientdb.sh ，server.sh，shutdown.sh），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并仅重现服务单元中的必要内容。

Answer 2

我添加了一个用户＆amp;将 orientdb 分组到系统并在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

Answer 3

如果运行服务器并关闭窗口，服务器将关闭。与NOHUP（server.sh）一起使用，如果关闭窗口，它将继续运行。

我有同样的问题，祝你好运

Answer 4

我在OpenSuse Leap 42.1和OrientDB 2.2.7中遇到了同样的问题。罗伯托的答案解决了这个问题。请参阅the issue on GitHub。

systemd在Ubuntu 16.04上启动后立即停止OrientDB
