如何使用Foreman正确关闭和转储Redis服务器？

Question

I have a Procfile that I use with Foreman to start my local redis and webrick server:

web: bundle exec rails server -p $PORT
redis: redis-server config/redis.development.conf

I connect to Redis using a named socket that is defined in the configuration like this:

unixsocket /tmp/redis-APPNAME.sock

Everything works fine in Rails, but when I hit CTRL + C to terminate Foreman in the terminal, the Redis DB is not dumped. The Redis server is terminated by SIGINT this way. So, whenever I restart the Foreman stack I get old Redis data.

Is there a way to tell Foreman to use the proper SHUTDOWN on Redis that will also dump the database? Or should I modify the Redis config to persist data all the time in development?

Answer 1

您是否尝试过使用包装脚本来发送SIGTERM ？

Answer 2

I ended up using Append-only File persistance on my development laptop for Redis instances. To turn it on you just have to add appendonly yes to your redis config. I left the fsync option to 1 second.

This way I always get persisted data when I terminate Foreman and switch to another project.
