Create MySQL User

Edit online

Important:

The collector only supports SNMPv3 authPriv and authNoPriv modes.
IP address used for MySQL queries must be the same as the value defined for the flag SEVONE_API_HOST.
You can skip this section if you are using the default value, 127.0.0.1, in SEVONE_API_HOST because the default values in MYSQL_USER & MYSQL_USER_PASSWORD i.e., root, <blank> are acceptable.

To create MySQL user, execute the following steps on the MySQL instance of SevOne NMS.

Note: FYI
SevOne NMS has two instances of MySQL - mysql and mysql2. For the following steps, only mysql is being used. The default port for mysql is TCP 3306 unless changed by the user to a different port.

The following allows the user to check the user's permission for the mysql instance.

$ SHOW GRANTS FOR '{user_name}'@'{host}';

SSH to SevOne NMS appliance.
```
$ ssh root@<NMS appliance>
```
Open a MySQL instance.
```
$ mysql
```
Note: For the following steps
- <user> is the username. This should also be provided as MYSQL_USER in the .env files for the collector.
- <ip_address> is the IP Address of the NMS (if running the collector on NMS) or the IP Address of the remote Virtual Machine (if running the collector on the remote Virtual Machine).
- <password> is the password to be set for the user. This should also be provided as MYSQL_USER_PASSWORD in the .env files for the collector.

Create a user.

$ CREATE USER '<user>'@'<ip_address>' IDENTIFIED BY '<password>';

Grant privileges to the user.

$ GRANT SELECT, EXECUTE ON *.* to '<user>'@'<ip_address>' identified by '<password>';

Important:
You must run the following command to measure the values of the Radio Signal Strength and Signal Noise indicators in dBm.

$ GRANT INSERT ON  *.*  to '<user>'@'<ip_address>' identified by '<password>';

Flush the privileges.
```
$ FLUSH PRIVILEGES;
```
