How To Install Percona Server 5.5 On Ubuntu 12.10

How To Install Percona Server 5.5 On Ubuntu 12.10

Percona Server is a drop-in replacement for MySQL. It offers more performance and scalability than the default MySQL server coming with your Linux distribution, while it uses the same init scripts and command line tools which makes it easy to use. This tutorial explains how to install Percona Server 5.5 on Ubuntu 12.10.

Installing Adito/OpenVPN-ALS On CentOS

Installing Adito/OpenVPN-ALS On CentOS

OpenVPN-ALS, formerly known as Adito, is not to be confused with OpenVPN. They both brilliant tools that work in completely different things, but in a similar way. Confused? Excellent… OpenVPN-ALS (from now on known as Adito, because I find it less confusing) is a browser based SSL VPN that enables you to acess resources on your own network, even if you are behind a restrictive proxy and/or firewall.

Distributed Replicated Storage Across Four Storage Nodes With GlusterFS 3.2.x On CentOS 6.3

Distributed Replicated Storage Across Four Storage Nodes With GlusterFS 3.2.x On CentOS 6.3

This tutorial shows how to combine four single storage servers (running CentOS 6.3) to a distributed replicated storage with GlusterFS. Nodes 1 and 2 (replication1) as well as 3 and 4 (replication2) will mirror each other, and replication1 and replication2 will be combined to one larger storage server (distribution). Basically, this is RAID10 over network. If you lose one server from replication1 and one from replication2, the distributed volume continues to work. The client system (CentOS 6.3 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

Configure Monit To Send SMS Instead Of Email

Configure Monit To Send SMS Instead Of Email

This tutorial helps you configure monit  to send alert messages using SMS to your mobile phone when a service fails instead of traditional email notification. Because monit can send only emails but not SMS, we will use an email-to-sms gateway where monit will send its emails to, and the email-to-sms gateway will convert the emails to SMS messages.

Using The btrfs Filesystem (With RAID1) With Ubuntu 12.10 On A Hetzner Server

Using The btrfs Filesystem (With RAID1) With Ubuntu 12.10 On A Hetzner Server

This tutorial shows how to install Ubuntu 12.10 on the btrfs filesystem (with RAID1) on a Hetzner server with two hard drives. While Hetzner's installimage tool doesn't list btrfs as a supported filesystem and only supports software RAID with /dev/md devices, it is still possible to achieve this setup and use the built-in RAID support in btrfs instead of using /dev/md devices.

Install Openldap From Source And Configure Multi-Master Replication

Install Openldap From Source And Configure Multi-Master Replication

Going forward to my previous document on setting up a Qmail Server with Openldap, I am now sharing a doc on how we can set up an Openldap in multi-master replication mode. So If you want more than one ldap-server for redundancy here we go.

Options For User Auditing On Linux Platforms

Options For User Auditing On Linux Platforms

A variety of methods exist for auditing user activity in UNIX and Linux environments. Some of them come preinstalled within common distributions, some can be downloaded as freeware, and some are commercially available products. Here are some of the most popular methods for auditing. Each method is described, along with tips for how to make the best use of each method. In addition, guidance is provided to show what type of auditing each method is best suited for.

High-Availability Storage With GlusterFS 3.2.x On CentOS 6.3 - Automatic File Replication (Mirror) Across Two Storage Servers

High-Availability Storage With GlusterFS 3.2.x On CentOS 6.3 - Automatic File Replication (Mirror) Across Two Storage Servers

This tutorial shows how to set up a high-availability storage with two storage servers (CentOS 6.3) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. The client system (CentOS 6.3 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.
