4 Start keosd and nodeos
This section provides guidance on how to start
To start a node, it is necessary to start two services —
mongo. To simplify the startup process, use the
docker-composeutility. Enter the directory where
docker-compose.ymlis located, and execute the services load command:
$ sudo docker-compose up -d
-dis 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
--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
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
cleosutility. This utility requires a running
keosdservice to store private keys. The
keosdservice can be started on user's computer via Docker.
keosdservice and connect it to the Docker network where
$ sudo docker run -ti -d --name keosd --net cyberway-net cyberway/cyberway:stable /opt/cyberway/bin/keosd
Assign alias to run
cleosin the container
$ 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
keosdservice 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
