Hallo,
ich möchte mein Apache2 und die my.cnf für mein System und Webseiten optimieren.
System: Debian 8, i5-2310 CPU @ 2.90GHz, 8GB RAM
Webseiten auf dem Server: 4. Insgesamt ca. 10.000 unique visitors täglich.
my.cnf:
MySQLTuner:
mpm_prefork.conf:
Kann mir jemand Tipps geben welche Werte ich hinzufügen oder hochschrauben kann?
LG

General recommendations:
Configure your accounts with ip or subnets only, then update your configuration with skip-name-resolve=1
Adjust your join queries to always utilize indexes
Increase table_open_cache gradually to avoid file descriptor limits
Read this before increasing table_open_cache over 64: http://bit.ly/1mi7c4C
Beware that open_files_limit (5000) variable
should be greater than table_open_cache (2000)
Variables to adjust:
join_buffer_size (> 256.0K, or always use indexes with joins)
table_open_cache (> 2000)
innodb_log_file_size should be equals to 1/4 of buffer pool size (=32M) if possible.mpm_prefork.conf:
Code:
<IfModule mpm_prefork_module>
StartServers 25
MinSpareServers 25
MaxSpareServers 50
MaxRequestWorkers 250
MaxConnectionsPerChild 1000
</IfModule>Kann mir jemand Tipps geben welche Werte ich hinzufügen oder hochschrauben kann?
LG
