The Ultimate Guide to High Availability with MariaDB

MariaDB for DirectAdmin using RPMs

Stai visualizzando una vecchia versione di questo article. Visualizza la versione più recente.

Se si utilizza DirectAdmin e si riscontrano problemi nell'Installare MariaDB con YUM, le istruzioni seguenti potrebbero essere d'aiuto. Il procedimento è molto diretto.

Nota: L'installazione di MariaDB tramite YUM è preferibile all'installazione manuale con i pacchetti RPM, perciò è bene seguire queste istruzioni solo se si verificano problemi come questo:

Starting httpd:
  httpd:
    Syntax error on line 18 of /etc/httpd/conf/httpd.conf:
    Syntax error on line 1 of /etc/httpd/conf/extra/httpd-phpmodules.conf:
      Cannot load /usr/lib/apache/libphp5.so into server:
        libmysqlclient.so.18: cannot open shared object file: No such file or directory

O come questo:

Starting httpd:
  httpd:
    Syntax error on line 18 of /etc/httpd/conf/httpd.conf:
    Syntax error on line 1 of /etc/httpd/conf/extra/httpd-phpmodules.conf:
      Cannot load /usr/lib/apache/libphp5.so into server:
        /usr/lib/apache/libphp5.so: undefined symbol: client_errors

RPM Installation

To install the RPMs, there is a quick and easy guide to Installing MariaDB with the RPM Tool. Follow the instructions there.

Necessary Edits

We do not want DirectAdmin's custombuild to remove/overwrite our MariaDB installation whenever an update is performed. To rectify this, disable automatic MySQL installation.

Edit /usr/local/directadmin/custombuild/options.conf

Change:

mysql_inst=yes

To:

mysql_inst=no

Note: When MariaDB is installed manually (i.e. not using YUM), updates are not automatic. You will need to update the RPMs yourself.
