4 Start keosd and nodeos
This section provides guidance on how to start
keosd and nodeosd services.To start a node, it is necessary to start two services —
nodeosd and mongo. To simplify the startup process, use the docker-compose utility. Enter the directory where docker-compose.yml is located, and execute the services load command:$ sudo docker-compose up -d
The option
-d is required to run container in background.To check if containers have been started successfully, run the following command:
$ sudo docker ps
To see text of log files, you can use the following commands:
$ sudo docker logs --tail 100 -f nodeosd
$ sudo docker logs --tail 100 -f mongo
Options:
--tail — sets a number of text lines;
-f — indicates that it is necessary to monitor the update log file.Check that the text of log files does not contain error messages. There should also be messages about created containers with the names
nodeosd and mongo. The text should have the following form:info 2019-03-07T06:57:09.024 thread-0 producer_plugin.cpp:1491 produce_block ] Produced block 00000c992d36ab56... #3225 @ 2019-03-07T06:57:09.000 signed by producera [trxs: 0, lib: 2564, confirmed: 0]
It should also have information about blocks received over the network:
info 2019-03-07T06:57:00.096 thread-0 producer_plugin.cpp:344 on_incoming_block ] Received block 6d6ac52bfe754174... #3222 @ 2019-03-07T06:57:00.000 signed by cyber [trxs: 0, lib: 2562, conf: 0, latency: 96 ms]
Connecting a node to blockchain is done using the
cleos utility. This utility requires a running keosd service to store private keys. The keosd service can be started on user's computer via Docker.Start the
keosd service and connect it to the Docker network where nodeosd is running:$ sudo docker run -ti -d --name keosd --net cyberway-net cyberway/cyberway:stable /opt/cyberway/bin/keosd
Assign alias to run
cleos in the container keosd:$ alias cleos='sudo docker exec -ti keosd cleos --url http://nodeosd:8888'
Check if your node has been connected to blockchain:
$ cleos get info
No errors should be while the services are running.
$ cleos wallet create --file wallet.pass
The
keosd service automatically locks storage if it is not in use. Storage can be unlocked using the command:$ cleos wallet unlock --password 'sudo docker exec -ti keosd cat wallet.pass'
To import your private key, you can use:
$ cleos wallet import --private-key <private-key>
In case of errors while container is running, it is recommended to stop the services, remove Docker volume and create it again. To stop the services, you can use:
$ sudo docker-compose down
To remove Docker volume, you can use the following command:
$ sudo docker volume rm cyberway-mongodb-data cyberway-nodeos-data
