How to Discover MySQL Databases by Shell

This task describes how to discover the MySQL databases by Shell and includes the following steps:

Prerequisites - Set up protocol credentials
This discovery uses the following protocols:
- SSH Protocol
- Telnet Protocol
- NTCMD Protocol
For credential information, see Supported Protocols.
Prerequisites - Retrieve information
To retrieve all relevant information, DFM must have read permissions for the $MYSQL_HOME directory and for executing mysqld (mysqld.exe or mysqld-nt.exe for Windows) with the following parameters:
```
mysqld --verbose --help
```
```
mysqld --version
```
If the my.cnf (my.ini) file is located outside the $MYSQL_HOME directory, you must add permissions for reading to it.
Run the discovery
1. Run the Range IPs by ICMP job to discover which of the machines in the IP range are up and running.
2. Run the Host Connection by Shell job to create Shell CITs.
3. Run any of host resources jobs to gather information about processes running on the host.
4. Run the MySQL by Shell job to discover information about MySQL configuration and replication.
