Start the Kaia service

Mon, 11 Jul 2022 18:37:31 +0900

1. Start the Kaia service. 1) Option 1 (Yum Repo), or Option 2 (Archive) with kcnd.service registered $ sudo systemctl status kcnd $ sudo systemctl start kcnd $ sudo systemctl status kcnd 2) Option 2 (Archive) without kcnd.service ** If you registered kcnd.service, use 1) instead. Starting with the script directly while the service is enabled makes systemd lose track of the process. $ sudo /kcn-linux-amd64/bin/kcnd status $ sudo /kcn-linux-amd64/bin/kcnd start $ sudo /kcn-linux-amd64/bin/kcnd status

Start the monitoring services

2. Start monitoring services. 1) Start the Telegraf service. $ sudo systemctl status telegraf $ sudo systemctl enable --now telegraf $ sudo systemctl status telegraf 2) Start the log shipper (Fluent Bit) service. ** Check that kcnd has created the log file first. $ ls -l /kaia/kcnd/logs/kcnd.out $ sudo systemctl enable --now fluent-bit $ sudo systemctl status fluent-bit ** If the log path is wrong, Fluent Bit keeps running without any error and ships nothing, so active (running) alone is not enough. Check that the log file is being watched: $ sudo journalctl -u fluent-bit -n 50 | grep inotify_fs_add ... [input:tail:tail.0] inotify_fs_add(): inode=... watch_fd=1 name=/kaia/kcnd/logs/kcnd.out ** If there is no such line, check the Path in /etc/fluent-bit/kaia-logs.conf.

3. Watch the service log to confirm if your node is correctly joined. ** If the node is not a proposer at that block, and the consensus is successful, the node have executed(==validates) the block. In other words, a block is inserted. ** You can refer this document for more details about node log. $ tail /kaia/kcnd/logs/kcnd.out INFO Inserted a new block number=14 hash=13cbfc…f007fc txs=0 gas=0 elapsed=793.458µs processTxs=167ns finalize=157.708µs validateState=7.542µs totalWrite=443.417µs trieWrite=256.667µs Please note that the above message will be found when Kaia operators add your node as a peer. So you may face the below messages instead. You can ignore error messages as below. It will disappear after some follow-up tasks from Kaia operators. err="Genesis block mismatch" err="unauthorized address" If you finish this step, please click the next button > on the right side of this page.
