## dump: dump requires nodetool in prod, nodetool is in `/usr/bin/` in dev environment, cassandra has been installed manually and nodetool is not in the path * dev should be aliegned to prod https://medium.com/@kayvan.sol2/deploying-apache-cassandra-cluster-3-nodes-with-docker-compose-3634ef8345e8 ## DOCKER instructions aggiungere a /etc/host l'entry: 127.0.0.1 cassandra start composer: `docker compose up --build` force recreate docker image `docker compose build --no-cache` check status: `docker exec -it cassandra1 nodetool status` ## import db `./dump.sh` `docker compose up --build` attendere che tutto sia pronto e i db siano sincronizzati TODO: definire esattamente come, tendenzialmente con nodetool status , nodetool gossip, etc eseguire uno dopo l'altro, quando sono terminati ```sh docker exec -it cassandra1 /scripts/setup.sh docker exec -it cassandra2 /scripts/setup.sh docker exec -it cassandra3 /scripts/setup.sh ``` flush before switch off ```sh docker exec -it cassandra1 nodetool flush docker exec -it cassandra1 nodetool flush docker exec -it cassandra1 nodetool flush ``` run a single service: * cassandra1: `docker compose up cassandra1 --build` * cassandra2: `docker compose up cassandra2 --build` * ,... cqlsh client: `docker exec -it cassandra1 cqlsh cassandra1 -k dev_keyspace_1` open bash on server * cassandra1: `docker exec -it cassandra1 bin/bash` * cassandra2: `docker exec -it cassandra2 /bin/bash` * cassandra3: `docker exec -it cassandra3 /bin/bash` ## check cassandra status Check status `nodetool status` Check if the Gossip protocol is enabled `nodetool info | grep -i gossip` Check the status of the Gossip protocol `nodetool gossipinfo` Check the communication between nodes `nodetool ring` ## Documentation * [cassandra dump data](docs/dump.md) * [cassandra setup and import](docs/setup.md)
