$ mysqldump -u root -p

MariaDB [recsys]> Use recsys;
Database changed

MariaDB [recsys]> source /home/adrianmarino1000/rec-sys/database/recsys_database.sql

MariaDB [recsys]> show tables;

    }
}

Step 21: Config installed miniconda path.

$ vim service.conf

export CONDA_PATH="$HOME/miniconda3"

Step 22: Install screen.

$ sudo apt install screen

Step 23: Open an screen session.

$ screen

Step 24: Get network interface name.

$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: ens4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1460 qdisc mq state UP mode DEFAULT group default qlen 1000
    link/ether 42:01:0a:96:00:03 brd ff:ff:ff:ff:ff:ff

Step 25: Setup port forwarding from 80 to 8000.

$ sudo rec-sys/bin/setup-port-forwarding ens4

Step 26: Start rec-sys app service.

$ systemctl --user restart recsys

Step 27: Ctrl+A and Ctrl+D to detack from screen session.

Step 28: Close ssh session.
