    Hey guys, I'm just wondering if anyone has a solid, basic my.cnf file setting that would serve well on a 1GB Linode VPS with 256MB Swap. @eva2000, I know you don't give help for free for this kind of thing, so it's all good. :)

    Just hoping someone else has a similar VPS setup that they'd be willing to share or help me out with. I've never gotten this far into server setups, so I am looking at a lot that I don't understand yet. I'd rather ask on here than blindly copying and pasting some random my.cnf on the web. lol

    Nice, but what to do? Should I manually change my.cnf with my.cnf from your link or there is a way to "download" that?

    Done! ;)

    Why is this line commented out in new version?
    #character-set-server=utf8

    you have to decide if you want it enabled... best if starting with new dataabases

    if importing data from other servers it's left disabled as other databases on other servers may default to latin1 and potentially mess with your data if you have importing server set it utf8

    I will than leave it as it is.
    But, my forum database (tables) are all in utf8, so I think that it will not be a problem even if I uncommented it out.

    Also, I have setup MariaDb to utf8 by default (for every new database).

    it's there.. check again after line transaction_prealloc_size = 4096

    You can check your mysql error log which is listed along with all other log file locations as per How to troubleshoot Centmin Mod initial install issues (/var/log/mysqld.log) for clues.

    For example, it can be related to different sized innodb_log_file_size compared to the initialised innodb instance on initial Centmin Mod install which defaults to 48M size.

    In /etc/my.cnf you can change the value of it
    Code:
    innodb_log_file_size = 48M
    
    restart mysql server and see

    if so, then to change from 48M to desired value and read official MySQL documentation for Changing Size of InnoDB Log Files. Only move/delete the log files ib_logfile0 and ib_logfile1

    is mysql root password populated in /root/.my.cnf too should be by default so no need to pass -u USER -p pass on mysql client command line

    setting under [mysqld] group character-set-server=utf8 option as per MariaDB MySQL - CentminMod.com LEMP Nginx web stack for CentOS should of done it if you had a proper mysql restart

    you should see
    Code:
    mysqladmin var | grep -E 'character|collation' | tr -s ' '
    | character_set_client | utf8 |
    | character_set_connection | utf8 |
    | character_set_database | utf8 |
    | character_set_filesystem | binary |
    | character_set_results | utf8 |

    There is a password, but default one. I have changed password yesterday, but it is not changed in .my.cnf automatically. Should I edit /root/.my.cnf end against old/default password put my new password?
    Edit - I changed, and still it is asked for password but accepted him when I wrote :)

    Now it is seems that is OK, maybe because mysql is properly restarted?

    i see the problem

    if you stop mysql and check process list, do any mysql processes still linger
    Code:
    mysqlstop
    ps aufx
    then mysqlstart again and check mysql error log latest lines
