Installation on Ubuntu

Add the RMON repository to your source list:

1. sudo echo \
2. "deb [arch=amd64, trusted=yes] https://repo.rmon.io/ubuntu \
3. $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/rmon.list > /dev/null

Run the following commands:

1. sudo apt update

Open the following link in your browser: https://your_ip/.

Use the default credentials: login - admin, password - admin.

If you get the "Internal error" after installation, install all requirements via pip3.

After the installation: Configuring RMON

After installing RMON, edit the /etc/rmon/rmon.cfg configuration file. The default configuration is shown below:

1. [main]
2. log_path = /var/log/rmon
3. lib_path = /var/lib/rmon
4. # Change secret_phrase to 32 url-safe base64-encoded
5. secret_phrase = _B8avTpFFL19M8P9VyTiX42NyeyUaneV26kyftB2E_4=
7. [mysql]
8. # By default Sqlite DB is used
9. enable = 0
10. mysql_user = rmon
11. mysql_password = rmon
12. mysql_db = rmon
13. mysql_host = 127.0.0.1
15. [pgsql]
16. # By default Sqlite DB is used
17. enable = 0
18. user = rmon
19. password = rmon
20. db = rmon
21. host = 127.0.0.1
22. port = 5432

Database settings

MySQL

The default database used by RMON is SQLite. If you want to use MySQL, make the following changes to the configuration file:

1. [mysql]
2. # By default Sqlite DB is used
3. enable = 0
4. mysql_user = rmon
5. mysql_password = rmon
6. mysql_db = rmon
7. mysql_host = 127.0.0.1
8. mysql_port = 3306

After editing the configuration file, create the RMON database on your MySQL server:

1. MariaDB [(none)]> create user 'rmon'@'%';
2. MariaDB [(none)]> create database rmon;
3. MariaDB [(none)]> grant all on rmon.* to 'rmon'@'%' IDENTIFIED BY 'rmon';
4. MariaDB [(none)]> grant all on rmon.* to 'rmon'@'localhost' IDENTIFIED BY 'rmon';

After creating the database, run the create_db.py script.

PostgreSQL

The default database used by RMON is SQLite. If you want to use PostgreSQL, make the following changes to the configuration file:

1. [pgsql]
2. # By default Sqlite DB is used
3. enable = 0
4. user = rmon
5. password = rmon
6. db = rmon
7. host = 127.0.0.1
8. port = 5432

After editing the configuration file, create the RMON database on your MySQL server:

1. # su - postgres
2. $ createuser rmon
3. $ createdb rmon
4. $ psql
5. postgres=# alter user rmon with encrypted password 'rmon';
6. postgres=# grant all privileges on database rmon to rmon;
7. postgres=# \c rmon
8. rmon=# GRANT ALL ON SCHEMA public TO rmon;

After creating the database, run the create_db.py script.

Configuring Apache

If you want to use a custom domain name, make changes to the Apache configuration file for RMON:

1. sudo vi /etc/httpd/conf.d/rmon.conf

If you want to enable redirection from port 80 to port 443, add the following lines to your configuration file:

1. <VirtualHost *:80>
2. ServerName my_domain.local
3. Redirect permanent "/" "https://my_domain.local/"
4. </VirtualHost>

Find the following lines and replace "rmon.example.com" with your domain name:

1. <VirtualHost *:443>
2. ...
3. ServerName my_domain.local
4. ...
5. </VirtualHost>

If you want to use custom certificates, edit the following lines:

1. <VirtualHost *:443>
2. ...
3. SSLEngine on
4. SSLCertificateFile /var/www/haproxy-wi/app/certs/haproxy-wi.crt
5. SSLCertificateKeyFile /var/www/haproxy-wi/app/certs/haproxy-wi.key
6. ...
7. </VirtualHost>

Generate SALT

RMON encrypts SSH passwords and SSH passphrases. To ensure that no one but you can decrypt your passwords, generate your own salt and put it in the /etc/rmon/rmon.cfg:

1. from cryptography.fernet import Fernet
2. key = Fernet.generate_key()
3. print(key)
