Configuring LTNM Node

Install Required Utilities

Install these useful LTNM utilities

sudo mkdir /opt/opsdude ; sudo -H chown ${USER}.${USER} /opt/opsdude ; cd /opt/opsdude
git clone https://github.com/tech-alchemist/ltnm-utils.git ; cd /opt/opsdude/ltnm-utils

Install latest binary on Server

cd /opt/opsdude/ltnm-utils && git pull origin master
bash install.sh

Starting LTNM node

cd /opt/opsdude/ltnm-utils && git pull origin master
bash start-node.sh

Stopping LTNM Node (Optional)

cd /opt/opsdude/ltnm-utils && git pull origin master
bash stop-node.sh

Additional Node Management

Add Auto Monitoring

To Auto-Start the stopped node, add cronjob for monitor script by:

cd /opt/opsdude/ltnm-utils && git pull origin master
crontab -l > /tmp/crontab.tmp
sed -i '/bash monitor.sh/d' /tmp/crontab.tmp
echo "## bash monitor.sh , Monitor script to keep LTNM node running ##" >>  /tmp/crontab.tmp
echo "*/2 * * * * cd /opt/opsdude/ltnm-utils && bash monitor.sh" >> /tmp/crontab.tmp
crontab /tmp/crontab.tmp

Compile LTNM Binary from Latest Source Code

Rather than using precompiled binaries, You can also compile binaries from latest source code by:

cd /opt/opsdude/ltnm-utils
bash compile.sh

(This process will be timetaking)

Nginx Config Generator For RPC Node

If your LTNM nodes are in private subnet/network, Nginx can be used as a gateway in that scenario.

Install Nginx Full by:

sudo apt install nginx-full
sudo systemctl enable nginx
sudo service nginx start

Map private machine/VM to Nginx server by:

cd /opt/opsdude/ltnm-utils
bash nginx.sh DOMAINNAME PROXYHOST PROXYPORT

Example:

bash nginx.sh example.main.ltnm.net 192.168.0.10 38555

This will create /etc/nginx/sites-enable/example.main.ltnm.net.conf with proxy mapped to Private RPC like : http://192.168.0.10:38555

Configure SSL cert for DNS/Domain mapped to Nginx:

sudo service nginx stop
sudo certbot certonly --standalone -d DOMAINNAME
sudo service nginx restart

Adding S3 Backup of Wallet Data

Configure S3 Bucket (Keep bucket private and highly secure)

AKEY="S3_User_Access_key"
SKEY="S3_User_Secret_key"
PROF="ltnm-backups"
mkdir ~/.aws/ ; touch ~/.aws/credentials ; chmod 600 ~/.aws/credentials
echo -ne "[${PROF}]\naws_access_key_id = ${AKEY}\naws_secret_access_key =  ${SKEY}\n" | tee ~/.aws/credentials

Check configured credentials after providing security from AWS IAM & S3

aws s3 --profile ltnm-backups ls s3://ltnm-backups/

Add cronjob for S3 backup

cd /opt/opsdude/ltnm-utils && git pull origin master
crontab -l > /tmp/crontab.tmp
sed -i '/bash backup.sh/d' /tmp/crontab.tmp
echo "## bash backup.sh , Daily Backup Script for configuredNodes and Wallet Data ##" >> /tmp/crontab.tmp
echo "00 00 * * * cd /opt/opsdude/ltnm-utils && bash backup.sh" >> /tmp/crontab.tmp
crontab /tmp/crontab.tmp
