# Systemd Setup For Backend Refreshes And Rebalancer Tools
|
|
|
|
You will need to fill in the proper username below in the paths marked `<run_as_user>`. This assumes you have installed lndg on the home directory of the user. For example, user `mynode` will have a home directory of `/home/mynode/`.
|
|
|
|
## Backend Refreshes
|
|
Create a simple bash file to call `jobs.py`, copying the contents below to the file and filling in your user.
|
|
`nano /home/<run_as_user>/lndg/jobs.sh`
|
|
```
|
|
#!/bin/bash
|
|
|
|
/home/<run_as_user>/lndg/.venv/bin/python /home/<run_as_user>/lndg/jobs.py
|
|
```
|
|
Create a service file for `jobs.sh`, copying the contents below to the file and filling in the user you would like this to run under.
|
|
`nano /etc/systemd/system/jobs-lndg.service`
|
|
```
|
|
[Unit]
|
|
Description=Run Jobs For Lndg
|
|
[Service]
|
|
User=<run_as_user>
|
|
Group=<run_as_user>
|
|
ExecStart=/usr/bin/bash /home/<run_as_user>/lndg/jobs.sh
|
|
StandardError=append:/var/log/lnd_jobs_error.log
|
|
```
|
|
|
|
Create a timer file for `jobs.sh`, copying the contents below to the file and change the 20s refresh if you like..
|
|
`nano /etc/systemd/system/jobs-lndg.timer`
|
|
```
|
|
[Unit]
|
|
Description=Run Lndg Jobs Every 20 Seconds
|
|
[Timer]
|
|

|
|
OnUnitActiveSec=20
|
|
AccuracySec=1
|
|
[Install]
|
|
WantedBy=timers.target
|
|
```
|
|
Enable the timer to run the jobs service file at the specified interval.
|
|
`sudo systemctl enable jobs-lndg.timer`
|
|
`sudo systemctl start jobs-lndg.timer`
|
|
|
|
## Rebalancer Runs
|
|
Create a simple bash file to call `rebalancer.py`, copying the contents below to the file and filling in your user.
|
|
`nano /home/<run_as_user>/lndg/rebalancer.sh`
|
|
```
|
|
#!/bin/bash
|
|
|
|
/home/<run_as_user>/lndg/.venv/bin/python /home/<run_as_user>/lndg/rebalancer.py
|
|
```
|
|
Create a service file for `rebalancer.sh`, copying the contents below to the file and filling in the user you would like this to run under.
|
|
`nano /etc/systemd/system/rebalancer-lndg.service`
|
|
```
|
|
[Unit]
|
|
Description=Run Rebalancer For Lndg
|
|

|
|
User=<run_as_user>
|
|

|
|
StandardError=append:/var/log/lnd_rebalancer_error.log
|
|
RuntimeMaxSec=3600
|
|
```
|
|
|
|
Create a timer file for `rebalancer.sh`, copying the contents below to the file and change the 20s refresh if you like.
|
|
`nano /etc/systemd/system/rebalancer-lndg.timer`
|
|
```
|
|
[Unit]
|
|
Description=Run Lndg Rebalancer Every 20 Seconds
|

|
|

|
|

|
|

|
|
```
|
|
Enable and start the timer to run the rebalancer service file at the specified interval.
|
|
`sudo systemctl enable rebalancer-lndg.timer`
|
|
`sudo systemctl start rebalancer-lndg.timer`
|
|
|
|
## HTLC Failure Stream Data
|
|
Create a simple bash file to call `htlc_stream.py`, copying the contents below to the file and filling in your user.
|
|
`nano /home/<run_as_user>/lndg/htlc_stream.sh`
|
|
```
|
|
#!/bin/bash
|
|
|
|
/home/<run_as_user>/lndg/.venv/bin/python /home/<run_as_user>/lndg/htlc_stream.py
|
|
```
|
|
Create a service file for `htlc_stream.sh`, copying the contents below to the file and filling in the user you would like this to run under.
|
|
`nano /etc/systemd/system/htlc-stream-lndg.service`
|
|

|
|
ExecStart=/usr/bin/bash /home/<run_as_user>/lndg/htlc_stream.sh
|

|
|
Restart=always
|
|
RestartSec=60s
|
|
[Install]

WantedBy=multi-user.target
|
|
```
|
|
Enable and start the service to run the htlc failure stream service file.
|
|
`sudo systemctl enable htlc-stream-lndg.service`
|
|
`sudo systemctl start htlc-stream-lndg.service`
|
|
|
|
## Status Checks
|
|
You can check on the status of your timers.
|
|
`sudo systemctl status jobs-lndg.timer`
|
|
`sudo systemctl status rebalancer-lndg.timer`
|
|
|
|
You can also check to make sure the last run of the service files triggered by the timers were successful.
|
|
`sudo systemctl status jobs-lndg.service`
|
|
`sudo systemctl status rebalancer-lndg.service`
|
|
|
|
You can disable your timers as well if you would like them to stop.
|
|
`sudo systemctl disable jobs-lndg.timer`
|
|
`sudo systemctl stop jobs-lndg.timer`
|
|
`sudo systemctl disable rebalancer-lndg.timer`
|
|
`sudo systemctl stop rebalancer-lndg.timer`
|
|
|
|
You can also check on and disable your htlc stream data.
|
|
`sudo systemctl status htlc-stream-lndg.service`
|
|
`sudo systemctl disable htlc-stream-lndg.service`
|
|
`sudo systemctl stop htlc-stream-lndg.service`
|
