Launch Cassandra

I am new to the Cassandra database. I downloaded Cassandra and installed JAVA_HOME. When I try to start, the following exception is thrown:

Exception thrown by the agent : java.rmi.server.ExportException: Port already in use: 7199; nested exception is:
java.net.BindException: Address already in use: JVM_Bind.

Can someone help me with this problem?

For those facing the same problem using Ubuntu OS, the solution might be to kill CassandraDaemon:

pkill -f CassandraDaemon

When you run the command “cassandra -f” for the first time to background daemons, so Ctrl ^ C does not stop the process.

It appears that Cassandra is already running in the background. Try connecting with cassandra-cli.

I am writing the same thing, but for the Windows Developer command line: let's say the problem is with port 9042

netstat -ano | findstr: 9042

List all processes using port 9042

Taskkill / PID 237979 / F

here 237979 is a process using port 9042
