I have just purchased a new dedicated server and currently using the defaults for MySQL and Apache. I'm looking to try and optimize the setup as best I can.
Here is the spec of the machine:
Intel Core i7-2600 Quad Core
8GB DDR3 RAM
CentOS 6.4 - 64-Bit
The spec is better than my previous machine, but the server load seems to be generally higher - I did do some tweaks on the previous machine, but I no longer have access to that machine to compare.
I'm not entirely sure what files I should be providing with regards to Apache - in order to optimize, but here are the ones for MySQL.
Here is the contents of /etc/my.cnf
I have run /usr/bin/mysqltuner.pl and this is what is showing - Everything has been running as it is for a tleast 8 days now:
I don't quite understand exactly what it is recommending.
Any help would really be appreciated with this.
Thanks in advance,
Daniel

-------- Recommendations -----------------------------------------------------
General recommendations:
Run OPTIMIZE TABLE to defragment tables for better performance
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
Increase table_cache gradually to avoid file descriptor limits
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)
table_cache (> 400)Any help would really be appreciated with this.
Thanks in advance,
