Redmine is an open source web application for project management and issue tracker. In this tutorial, we will install Redmine 3.2 with Nginx as the web server, MySQL as the database server on a CentOS 7 (64 bit) operating system.
Historically I do not care much about MariaDB's MaxScale, at least since I know how to build it from source when needed. But,
as a support engineer who work at MariaDB, sometimes I have to
deal with problems related to MaxScale, and this week it happened
so that I had to explain what to do to implement automatic
restarts of MaxScale "daemon" in case of crashes on RHEL
In the process I had found out that two of my most often used Linux distributions, CentOS 6.x and Ubuntu 14.04, actually use Upstart, so good old System V's init tricks and scripts work there only partially and only because somebody cared to integrate them into this "new" …
In this tutorial, I will show you how to install and configure Percona XtraDB Cluster on a CentOS 7 server. We will use Percona XtraDB Cluster 5.6 that is fully compatible to MySQL and the Percona Server.
In this article, I will describe how you can monitor your CentOS 7.2 server with Munin and Monit. Munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas Monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that lets you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services.
This document describes how to install a PureFTPd server that uses virtual users from a MariaDB (MySQL compatible) database instead of real system users. This is much more performant and allows to have thousands of FTP users on a single machine. In addition to that, I will show the use of quota and upload/download bandwidth limits with this setup. Passwords will be stored encrypted as MD5 strings in the database.
Nginx (pronounced "engine x") is a free, open-source, high-performance HTTP server. Nginx is known for its stability, rich feature set, simple configuration, and low resource consumption. This tutorial shows how you can install Nginx on a CentOS 7.2 server with PHP support (through PHP-FPM) and MySQL (Mariadb) support.
This tutorial shows how to install ISPConfig 3.1 on a CentOS 7.2 (64Bit) server. ISPConfig 3 is a web hosting control panel that allows you to configure the following services through a web browser: Apache web server, Postfix mail server, MySQL, BIND nameserver, PureFTPd, SpamAssassin, ClamAV, Mailman, and many more.
Lighttpd is a secure, fast, standards-compliant web server designed for speed-critical environments. This tutorial shows how you can install Lighttpd on a Centos 7 server with PHP support (through PHP-FPM) and MySQL support. PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with some additional features useful for sites of any size, especially busier sites. I use PHP-FPM in this tutorial instead of Lighttpd's spawn-fcgi.
In this blog post, we’ll discuss some of the basics regarding Docker MySQL replication. Docker has gained widespread popularity in recent years as a lightweight alternative to virtualization. It is ideal for building virtual development and testing environments. The solution is flexible and seamlessly integrates with popular CI tools.
This post walks through the setup of MySQL replication with Docker using Percona Server 5.6 images. To keep things simple we’ll configure a pair of instances and override only the most important variables for replication. You can add whatever other variables you want to override in the configuration files for each instance.
Note: the configuration described here is suitable for development or testing. We’ve also used the …[Read more]
MySQL Cluster is designed to provide a MySQL compatible database with high availability and low latency. The MySQL Cluster technology is implemented through the NDB (Network DataBase) and NDBCLUSTER storage engines and provides shared-nothing clustering and auto-sharding for MySQL database systems. In the shared-nothing architecture, each of nodes has its own memory and disk, the use of shared storage such as NFS, SANs is not recommended and supported.
