Intro

GoAccess was designed to be a fast, terminal-based log analyzer. Its core idea is to quickly analyze and view web server statistics in real time without needing to use your browser (great if you want to do a quick analysis of your access log via SSH, or if you simply love working in the terminal).

GoAccess

moov position is the key for web friendly mp4, it should be ahead of mdat, the following shell checks the moov position and moves it to the right place.

Problem Description

apache2 can not access the symbolic link which located in default directory. Gives error “Forbidden You don’t have permission to access … on this server”.

Install the Latest Version

If you’re using yum to install software in CentOS, most likely it is not the latest version, just like install phpMyAdmin, run yum install phpmyadmin, it will only install version 4.4, which the latest version is 5.02 at the time I’m writing this article.

When a new server is setup or when it restarted, we encounter the problems like can not access the website every now and then. Mostly, we should just check firewall and selinux.

This article is about the procedure to hot backup and configure a replication of MySQL sever.
The configuration servers are IP with 200 as master and 64 as slave;

Preparation:

It’s a good practice to check your work station first before you do anything, you have to know as more as possible including the hardware and system limitation, so that you can get a rough idea when encountered with a problem.
