Install latest nginx version on Ubuntu 14.04

Published on 09.09.2015

We know that sometimes the guys from ubuntu don't update repositories with latest versions of software, so there is quick way to use official nginx repo for installing it.

#Add nginx keys
wget -O - http://nginx.org/keys/nginx_signing.key | sudo apt-key add -

#Backup current sources
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

#Add following repositories to ` /etc/apt/sources.list`
echo "deb http://nginx.org/packages/mainline/ubuntu/ trusty nginx" | sudo tee -a /etc/apt/sources.list
echo "deb-src http://nginx.org/packages/mainline/ubuntu/ trusty nginx" | sudo tee -a /etc/apt/sources.list

#Update repositories and install nginx
sudo apt-get update
sudo apt-get install nginx

Installation of latest version of Go Lang on Ubuntu

Published on 05.09.2015

Installing Go on Ubuntu is pretty easy. We can do that with apt-get manager but i preffer to do it with downloading from official site.
Last version of the time of writing this is 1.5. So we can download it from https://golang.org/dl/

curl -O https://storage.googleapis.com/golang/go1.5.linux-amd64.tar.gz

After that we must unpack it into

/usr/local

tar -C /usr/local -xzf go1.5.linux-amd64.tar.gz

After that we must set some

env

variables.

mkdir -p ~/go; echo "export GOPATH=$HOME/go" >> ~/.bashrc
echo "export PATH=$PATH:$HOME/go/bin:/usr/local/go/bin" >> ~/.bashrc
source ~/.bashrc

And finally we have it:

root@golang:~# go version
go version go1.5 linux/amd64

Python as fake syslog server

Published on 18.08.2015

Simple and quick script which simulate syslog server.
It can be started with

server.py --udp --tcp

__author__ = 'Yuks'

import argparse
import SocketServer

from threading import Thread

PORT = 514
HOST = ""

class MySocketServerHandler(SocketServer.BaseRequestHandler):

    def handle(self):
        print  self.request[0].strip()
    

def start_udp():
    print("Starting UDP Server at port %s " % PORT)
    server_s = SocketServer.UDPServer((HOST, PORT), MySocketServerHandler)
    server_s.serve_forever()


def start_tcp():
    print("Starting TCP Server at port %s " % PORT)
    server_s = SocketServer.TCPServer((HOST, PORT), MySocketServerHandler)
    server_s.serve_forever()


if __name__ == "__main__":
    print "Starting server...."

    parser = argparse.ArgumentParser(description='Bugtower rsyslog server')
    parser.add_argument('--tcp', help='Start TCP server', action='store_true', default=False, required=False)
    parser.add_argument('--udp', help='Start UDP server', action='store_true', default=False, required=False)
    parser.add_argument('--port', help='Port for servers', default=514, required=False)
    args = parser.parse_args()

    PORT = int(args.port)

    if args.udp:
        t = Thread(target=start_udp)
        t.start()
    if args.tcp:
        t2 = Thread(target=start_tcp)
        t2.start()
