Optimize PHP and MySQL Request

Thorsten H.
Hello, I have a big performanceproblem with my kvm-server. It is running cPanel 11.58 - ea-apache24-mod_mpm_worker - MariaDB 10.0 I have some tables in one database with more than 1.000.000 enties. This database is very large; the engines are mixed - innoDB and MyISAM. When I ran HTOP all 4 cores are running at 100% all the time with php-cgi command using the CPU. When I run mysqltuner.pl this is the output:

So my question is, where to start searching for the problem. Can anyone help me and give me tips to optimize PHP and mysql?

    Some key details that you've already got:

    Hello InfoPro, you are right, but the hardfacts (RAM, RAM used by MySQL) will not change over the runtime I think. But now I will/have to wait until 1 day or so is over. But I'm also glad to get some tipps to optimize PHP and MySQL. Regards Thorsten

    It looks by your my.cnf that you already got some tips. If it was me I think I would remove all of that from the my.cnf, restart MySQL, and then let it run 24 hours.

    Hello, was that a joke or do you mean it regular? I'm afraid, that the MariaDB-Server will crash - and it is a productive server, so I don't want to play around with it.

    Your my.cnf is not default of course, someone has made some changes to it. My guess is your problems are there. The docs may be of some use to you to get a default my.cnf: mysqld Configuration Files and Groups Configuring MariaDB with my.cnf

    Hello, it sounds a bit strange, but I tried it - renaming the my.cnf and restarting mysql/MariaDB. The first start without confi-file was a bit slow but not so bad. the messuring with mysqltuner.pl gave some recommendations the I included into a new my.cnf. Now I will wait 1 or 2 days to see what will happen. What I have seen by now is, that the memory used is going dowm from 5.7 GB to just 1,8 GB. Here are the outputs and the, realy small, my.cnf

    Hi Thorsten H. Just a thort. Did you check the IOPS the server can do and if it is not overloading the Disk IOPS Thanks

  • Thorsten H.
    Hello Pacific... I have the parameters but have not checked it by now, because I don't know good or bad values for that. Here are the values from yesterday: Disk IO (read/write per sec.) between 100 and 350 with one spike up to 900 Last month all between 100 and spikes to 350/400. So I think they are OK. And I changed/added some parameters to my.cnf This is the actual one:
    [mysqld] bind-address = 127.0.0.1 # 15.09.2016 skip-name-resolve = 1 # 15.09.2016 thread_cache_size = 4 # 15.09.2016 table_open_cache = 1000 # 400 15.09.2016 - 1000 16.09.2016 join_buffer_size = 256K # 128k 15.09.2016 - 256k 16.09.2016 query_cache_type = 0 # 0 15.09.2016 tmp_table_size = 24M # 16M 15.09.2016 - 24M 16.09.2016 max_heap_table_size = 24M # 16M 15.09.2016 - 24M 16.09.2016 key_buffer_size = 268M # 268M 15.09.2016 innodb_buffer_pool_size = 950M # 950M 15.09.2016 innodb_buffer_pool_instances = 1 # 1 15.09.2016 max_connections = 200 # 200 16.09.2016 wait_timeout = 30 # 30 16.09.2016 interactive_timeout = 30 # 30 16.09.2016
    Any sugestions?
