To What Extent Can One Rely on Writing to Disk When SIGTERM is Given?

妖精的绣舞 提交于 2021-02-07 08:44:42
问题 I am developing for Linux and have a daemon that should write to disk when it is killed. The daemon could be configured to listen to SIGTERM and write to disk when that signal is received. I am also familiar with the PrepareForShutdown D-Bus signal issued by the login manager. Listening to SIGTERM results in simpler code than inhibiting shutdown and listening to the PrepareForShutdown signal. Another advantage of SIGTERM is that it handles cases where the daemon is politely killed even though

Forcing work directory when executing jar file in systemd

问题 I have got an array @address whose zero element contains some strings. I can not find an example diamond operator works with @array as argument.

docker daemon的HTTP socket TLS加密连接

默认docker daemon是通过非网络的unix socket监听客户端连接的.如果我们需要客户端通过网络来安全的连接到docker daemon,则因该配置TLS加密方式,通过http的方式来连接. 使用openssl来创建ca证书,并签发密钥.

Running celery as daemon does not create PID file

为君一笑 提交于 2020-12-30 05:53:26
问题 I have been scratching my brains on this one since past few days, I have seen other issues on stackoverflow (as it is a duplicate question) and I have tried everything to make this work, the workers are running fine but the celery is not starting up as a process. I run the command: sudo service celeryd start and I get: celery init v10.1. Using config script: /etc/default/celeryd celery multi v3.1.23 (Cipater) > Starting nodes... > worker1@ip-172-31-21-215: OK I run: sudo service celeryd

Is it possible to set up MongoDB in a shared hosting environment? [closed]

喜你入骨 提交于 2020-12-24 07:12:51
问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 7 years ago . Improve this question I'm using GoDaddy and would like to use MongoDB for a pet project. I'm not sure it is possible though, since it has to be running the daemon, but, it doesn't hurt to ask, is there a way? EDIT: They've closed the question, but if anybody stumbles upon this post with the same question: While
