This article introduces the relevant knowledge of "how to deploy Open-Falcon monitoring system under Linux". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Open-Falcon is a humanized Internet enterprise monitoring system. The whole Open-Falcon can be divided into two parts, namely, drawing component and alarm component. Where:

The installation drawing component is responsible for data collection, collection, storage, archiving, sampling, query, display (Dashboard/Screen) and other functions, which can work alone as a storage and display scheme of time-series data. The installation alarm component is responsible for alarm policy configuration (portal), alarm decision (judge), alarm processing (alarm/sender), user group management (uic), etc., and can work independently. Deployment

Open-Falcon uses server-agent to realize monitoring. Here are the details of the deployment:

Integrated deployment backend

In this test environment, stand-alone deployment is carried out, and all modules are placed on one host.

Environmental preparation

The back-end components of open-falcon are written in the GE language, so we need to install the GE language development environment first.

Yum install golang-y # # requires epel source export GOROOT=/usr/lib/golangexport GOPATH=/home

Install redis

Yum install-y redis1

Install mysql and start

Yum install-y mysql-server/etc/init.d/mysqld start

# # the test machine is centos6, and the rest of the system changes the startup command on its own

Initialize the MySQL table structure

Cd / tmp/ & & git clone https://github.com/open-falcon/falcon-plus.gitcd / tmp/falcon-plus/scripts/mysql/db_schema/mysql-h 127.0.0.1-u root-p

Installation

Create a working directory

Export FALCON_HOME=/home/workexport WORKSPACE=$FALCON_HOME/open-falconmkdir-p $WORKSPACE

Download the compiled binary package and extract it

Wget https://github.com/open-falcon/falcon-plus/releases/download/v0.2.1/open-falcon-v0.2.1.tar.gztar-xzvf open-falcon-v0.2.1.tar.gz-C $WORKSPACE

Configuration file

Before starting, you need to modify the configuration files of each module to ensure that the user name and password of the database are correct. The following is the configuration file path for each module.

Aggregator/ home/work/aggregator/config/cfg.jsongraph / home/work/graph/config/cfg.jsonhbs / home/work/hbs/config/cfg.jsonnodata / home/work/nodata/config/cfg.jsonapi / home/work/api/config/cfg.jsonalarm / home/work/alarm/config/cfg.json

Start

Cd $WORKSPACE./open-falcon start

# check the startup status of all modules
