It also provides access control and several collaboration features, such as a wikis and basic task management tools for every project.

This post is going to show some basic GitHub usage during my learning.

  • Create your first new file
  • Fork
  • Get the link to direct download file

Install Nginx, MariaDB, PHP (LEMP) and WordPress on GCP Free Tier Ubuntu

I was using LAMP for my WordPress blog for quite a few years. Because of Google Cloud Platform free tier VM's limitation (614M Memory and 1 vCPU), my website always suffering the performance issue if put all of components into one machine. Since last year, I keep trying using a different type of technologies to help. I tried to use Docker, also I separated Mysql db into a different vm. All those changes were working for certain conditions, but not a good enough for GCP f1.micro VM until I find Nginx and MariaDB. This combination has less resource usage and also providing me a possibility to squeeze all components into one GCP free tier f1.micro VM.

This post is to record all steps and commands I used. You will find a YouTube video at the end of post to present the installation process. The whole steps will take 30 minutes to 45 minutes to complete.

Easily Deploy ELK Stack into CentOS 7

The Elastic Stack — formerly known as the ELK Stack — is a collection of open-source software produced by Elastic which allows you to search, analyze, and visualize logs generated from any source in any format, a practice known as centralized logging. Centralized logging can be very useful when attempting to identify problems with your servers or applications, as it allows you to search through all of your logs in a single place. It’s also useful because it allows you to identify issues that span multiple servers by correlating their logs during a specific time frame.
The Elastic Stack has four main components:
  • Elasticsearch: a distributed RESTful search engine which stores all of the collected data.
  • Logstash: the data processing component of the Elastic Stack which sends incoming data to Elasticsearch.
  • Kibana: a web interface for searching and visualizing logs.
  • Beats: lightweight, single-purpose data shippers that can send data from hundreds or thousands of machines to either Logstash or Elasticsearch.
