Help with MySQLTuner on E3-1240 / 24GB

Server Specifications:

Xeon E3-1240
24GB DDR3
2x2TB RAID 1
1Gbps unmetered

I'm not entirely sure, and not at all knowledgeable, about mysql optimisation - I was hoping someone on here might be able to tell me the best my.cnf to set.

Here are the results from MySQLTuner

-------- Recommendations -----------------------------------------------------
General recommendations:
    Run OPTIMIZE TABLE to defragment tables for better performance
    MySQL started within last 24 hours - recommendations may be inaccurate
    Enable the slow query log to troubleshoot bad queries
    Adjust your join queries to always utilize indexes
    When making adjustments, make tmp_table_size/max_heap_table_size equal
    Reduce your SELECT DISTINCT queries without LIMIT clauses
    Set thread_cache_size to 4 as a starting value
Variables to adjust:
    query_cache_size (>= 8M)
    join_buffer_size (> 128.0K, or always use indexes with joins)
    tmp_table_size (> 16M)
    max_heap_table_size (> 16M)
    thread_cache_size (start at 4)

And here is my current my.cnf

[mysqld]
local-infile=0
innodb_file_per_table=1
default-storage-engine=MyISAM
key_buffer_size=1024M
max_connections=5000
innodb_buffer_pool_size=2028M

Appreciate anyone who takes the time to look and advise, thank you.

The most important line in the mysqltuner comment you posted is this:

MySQL started within last 24 hours - recommendations may be inaccurate

You can't hope to get a clear picture using mysqltuner until your server has been running at least 24 hours, preferably 48 hours.

Hello

Yes, please let us know the output after MySQL has been running longer than 24 hours.

Thank you.

Here's an updated version after letting it run for longer:
