Sysadmin notes

In the past year, closed repository CentAlt which had a lot of useful things for servers with Centos 5-6. Now much of the fact that there were already out of date, but still it is very necessary. The network has several mirrors, but it packs have not been updated since the closure CentAlt.

We have created its mirror, slightly enlarged and updated. Address our repository http://repo.webpatron.net/Centos/. For Centos 5 there available php 5.2.17, apache 2.2.27 with support for mpm-itk, mod_rpaf and more. For Centos 6 - php 5.3.29, apache 2.2.29 with support for mpm-itk, mod_rpaf, mariadb, mysql 5.5.37, and a bunch of other essential packages.

Hard drive - the most vulnerable spot any server. If you take the possible failure of "iron" that often fails is the hard drive. At the same time there is also a huge risk of data loss (unless of course fails to make backups). Under this state hard drive is required to monitor and replace them immediately after a problem occurs.

This will help S.M.A.R.T., which will constantly monitor the disks and if the problem will notify you by email. S.M.A.R.T. - A technology for self-diagnosis and prediction of possible hard drive failure.

There are many reasons to use the VPN server for the Internet. This hide your location, and access to resources that are not available from your country, and anonymity, and access blocked sites, but the main reason - is security.

With VPN creates an encrypted tunnel from your computer to our VPN-server and back. This allows you to protect any data being transmitted from interception on any key nodes, whether public Wi-Fi router or your Internet Service Provider.

The easiest way to organize your own VPN server using OpenVPN. His installation, configuration and use will be discussed below.

RadioCMS - a unique control system radio station through a web-browser. With it, anyone can create their own online radio station. All you need - is to have a virtual or dedicated server and install the necessary software.

Description of the system is available on the official website. Yet software developers recommend the use of the operating system Ubuntu, Debian or FreeBSD, we're going to install on Centos 6.x.

Today, faced with the problem of installing php module libssh2 on a server with Centos 6.6 and PHP 5.4.37.

A simple way, like team pecl install ssh2, the module becomes refused flies error "Failed to download pecl/ssh2 within preferred state "stable", latest release is version 0.12, stability "beta", use "channel://pecl.php.net/ssh2-0.12" to install install failed".

To deal with this, I did not, and went the other way.
