To log into your server, you will need to know your server’s public IP address. In this tutorial, we will learn how to log into our server as the root user, create a new user with admin privileges, and set up a basic firewall. This will increase the security and usability of your server and will give you a solid foundation for subsequent actions. When installing Galera Cluster for MySQL on CentOS, versions 6 and 7, you may encounter a transaction check-error that blocks the installation.When you first create a new Debian 11 server, there are a few configuration steps that you should take early on as part of the basic setup. For more information, see Migrating to Galera Cluster. If you installed Galera Cluster for MySQL over an existing stand-alone instance of MySQL, there are some additional steps that you’ll need to take to update your system to the new database server. Before confirming the installation of packages, make sure that the package manager is planning to install the Galera Cluster version you want.
Incidentally, when deciding which packages from the Codership repository to install, the package manager may elect to install a newer major verion of Galera Cluster, newer than the one you intended to install. You will then have to repeat this process for each node in your cluster, including enabling the repository files mentioned earlier. Once you’ve executed the line appropriate to your distribution and package manager, Galera Cluster for MySQL should be installed on your server. To import the GPG key, execute the following from the command-line on your server:
For an explanation on installing, skip ahead on this page to the section entitled, Installing Galera Cluster for MySQL.įor servers with Linux distributions that use zypper for package management (e.g., openSUSE and SUSE Linux Enterprise Server), you can enable the Codership repository by importing the GPG key and then creating a galera.repo file in the local directory. This could be changed to x86_64 for 64-bit systems.Īfter you’ve created, modified, and saved this repository file, you’ll be able to install the packages from the Codership repository using yum. Last, the ARCH indicates the architecture of your hardware. It might be 6 for CentOS, but 20 or 21 for Fedora. The RELEASE should be replaced with the distribution’s release number. The DIST should be changed to the name of the Linux distribution you’re using on your sever (e.g., centos or fedora). The VERSION should be set to the whichever MySQL-wsrep version you want (e.g., it might be 5.6). In this sample repository configuration file, you would change the repository addresses for the baseurl. Name = Galera baseurl = gpgkey = gpgcheck = 1 name = MySQL-wsrep baseurl = gpgkey = gpgcheck = 1
