Running Seid

How to start and run seid on a full node

Prerequisites

This section assumes that you have set up a full node, configured all settings and joined a network.

Run Seid

You may run seid with

seid start

If you want to see all the flags, you can use

> seid start --help

Run the full node application with Tendermint in or out of process. By
default, the application will run with Tendermint in process.
 
Pruning options can be provided via the '--pruning' flag or alternatively with '--pruning-keep-recent',
'pruning-keep-every', and 'pruning-interval' together.
 
For '--pruning' the options are as follows:
 
default: the last 100 states are kept in addition to every 500th state; pruning at 10 block intervals
nothing: all historic states will be saved, nothing will be deleted (i.e. archiving node)
everything: all saved states will be deleted, storing only the current and previous state; pruning at 10 block intervals
custom: allow pruning options to be manually specified through 'pruning-keep-recent', 'pruning-keep-every', and 'pruning-interval'
 
Node halting configurations exist in the form of two flags: '--halt-height' and '--halt-time'. During
the ABCI Commit phase, the node will check if the current block height is greater than or equal to
the halt-height or if the current block time is greater than or equal to the halt-time. If so, the
node will attempt to gracefully shutdown and the block will not be committed. In addition, the node
will not be able to commit subsequent blocks.
 
For profiling and benchmarking purposes, CPU profiling can be enabled via the '--cpu-profile' flag
which accepts a path for the resulting pprof file.
 
The node may be started in a 'query only' mode where only the gRPC and JSON HTTP
API services are enabled via the 'grpc-only' flag. In this mode, Tendermint is
bypassed and can be used when legacy queries are needed after an on-chain upgrade
is performed. Note, when enabled, gRPC will also be automatically enabled.

Systemd

Seid should be running at all times, it's reccomended you register Seid as a systemd service so that it will be automatically restarted if your system reboots

Create a definition file in /etc/systemd/system/seid.service

[Unit]
Description=Sei Node
After=network.target
 
[Service]
User=<USER>
Type=simple
ExecStart=<PATH_TO_SEID>/seid start --chain-id <Network>
Restart=always
 
# wait 30 seconds before restarting the service after it has failed.
RestartSec=30
 
#  wait up to 30 seconds for the service to stop gracefully when it is being stopped.
TimeoutStopSec=30
 
# send the SIGINT signal (equivalent to pressing Ctrl-C) to the service process when it is being stopped
# giving it a chance to shut down gracefully.
KillSignal=SIGINT
 
LimitNOFILE=65535
 
[Install]
WantedBy=multi-user.target

Modify the file with the proper path and Network.

<PATH_TO_SEID> - Enter the path to the Seid executable. <PATH_TO_SEID> is likely /home/<YOUR_USER>/go/bin/seid or /usr/go/bin. Confirm this with whereis seid.
<USER> Enter the user (likely your username or root, unless you created a user specifically for Seid).
<Network> the Chain that this seid binary runs on
Make sure you made the correct edits to /etc/security/limits.conf.

Run systemctl daemon-reload followed by systemctl enable seid. This will register seid as a system service and run the program upon startup.

Controlling the service

Use systemctl to start, stop and restart the service.

# Check health
systemctl status seid
# Start
systemctl start seid
# Stop
systemctl stop seid
# Restart
systemctl restart seid

Use journalctl -t to access entire logs, entire logs in reverse, and the latest and continuous log.

# Entire log reversed
journalctl -t seid -r
# Entire log
journalctl -t seid
# Latest and continuous
journalctl -t seid -f
# Since 30 minutes ago
journalctl -t seid --since -30m

(Optional) Cosmovisor

You may also want to use Cosmovisor such that it's easier to manage upgrades, it's a wrapper around the default seid binary, to install it:

curl -Ls https://github.com/cosmos/cosmos-sdk/releases/download/cosmovisor%2Fv1.3.0/cosmovisor-v1.3.0-linux-amd64.tar.gz | tar xz
chmod 755 cosmovisor
sudo mv cosmovisor /usr/bin/cosmovisor
 
sudo tee /etc/systemd/system/seid.service > /dev/null << EOF

#  wait up to 30 seconds for the service to stop gracefully when it is being stopped.
TimeoutStopSec=30
 
# send the SIGINT signal (equivalent to pressing Ctrl-C) to the service process when it is being stopped
# giving it a chance to shut down gracefully.
KillSignal=SIGINT

sudo systemctl daemon-reload
sudo systemctl enable seid

The folder layout is expected to be

.
├── current -> genesis or upgrades/<name>
├── genesis
│   └── bin
│       └── $DAEMON_NAME
└── upgrades
    └── <name>
        └── bin
            └── $DAEMON_NAME

The cosmovisor/ directory includes a subdirectory for each version of the application (i.e. genesis or upgrades/<name>). Within each subdirectory is the application binary (i.e. bin/$DAEMON_NAME) and any additional auxiliary files associated with each binary. current is a symbolic link to the currently active directory (i.e. genesis or upgrades/<name>). The name variable in upgrades/<name> is the URI-encoded name of the upgrade as specified in the upgrade module plan.

Please note that $DAEMON_HOME/cosmovisor only stores the application binaries. The cosmovisor binary itself can be stored in any typical location (e.g. /usr/local/bin). The application will continue to store its data in the default data directory (e.g. $HOME/.sei) or the data directory specified with the --home flag. $DAEMON_HOME is independent of the data directory and can be set to any location. If you set $DAEMON_HOME it to the same directory as the data directory, you will end up with a configuration like the following:
