Python on Ubuntu Notes
See My Python Notes for information not specific to Ubuntu and Python.
Verify Python 3 is installed
anon@hammerhead:~$ python --version Command 'python' not found, but can be installed with: sudo apt install python3 sudo apt install python sudo apt install python-minimal You also have python3 installed, you can run 'python3' instead. anon@hammerhead:~$ python3 --version <----- Python 3 installed. Python 3.6.7 <----- Version 3.6.7
Verify Python 3 PIP installed
$ pip3 --version pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.6)
To install Python 3 PIP
$ sudo apt-get install -y python3-pip
I use Python virtual environments. Verify Python venv module is installed
$ apt list -a --installed *venv* <----- If nothing with Python 3 venv comes back then you most install venv module
To install Python 3 venv module
$ sudo apt-get install -y python3-venv
Create virtual environment. I keep my Python virtual environments in a single directory. To create directory $ mkdir python-venv
Switch do directory $ cd python-venv/
Create virtual environment
$ python3 -m venv udmey-django
Activate virtual environment
$ source udmey-django/bin/activate
Prompt changes to reflect virtual environment
(udmey-django) anon@hammerhead:~/python-venv$
Note: Within virtual environment, you can use the command python instead of python3, and pip instead of pip3.
Deactivate virtual environment and prompt returns to normal
$ deactivate

Install and run MongoDB Community Edition on Ubuntu 18.04 LTS
The site has excellent documentation so I am simply providing overview of steps.
- Import the public key used by the package management system.
- Create a list file for MongoDB.
- Reload local package database.
- Install the MongoDB packages.
Run MongoDB Community Edition
- Start MongoDB with
sudo service mongod start - Verify that MongoDB has started successfully with
sudo grep port /var/log/mongodb/mongod.log - Stop MongoDB with
sudo service mongod stop - Restart MongoDB with
sudo service mongod restart - Begin using MongoDB shell with
mongo
Running mongo shell for first time
$ mongo
MongoDB shell version v4.0.10
connecting to: mongodb://127.0.0.1:27017/?gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("<uuid_value>") }
MongoDB server version: 4.0.10
Welcome to the MongoDB shell.
For interactive help, type "help".

Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).
The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.
To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()

Windows 10 (dev environment)
Download MongoDB Community Edition zip package
Extract downloaded file and rename to root directory to mongodb.
Move mongodb directory to user profile. On my Windows 10 dev machine the absolute path is C:\Users\anon\mongodb.
Create directory in same profile that will hold mongodb collections called mongodb-data. The absolute path is C:\Users\anon\mongodb-db.
To run MongoDB open shell in C:\Users\anon\mongodb\bin directory and type .\mongod.exe --dbpath=\Users\anon\mongodb-data\

Teamspeak 3 setup on Ubuntu 16.04 and 18.x via command line
Followed steps at How to install Teamspeak 3 server on Ubuntu 16.04 64-bit to install Teamspeak 3 and get basic server running.
If you want to customize the server port follow next steps.
Install simple command-line program named sqlite3. How to use sqlite
robot00@apu00:~$ sudo apt install sqlite3
Launch sqlite3 using Teamspeak 3 sqlite database file:
robot00@apu00:~$ sudo sqlite3 /home/teamspeak/ts3server.sqlitedb SQLite version 3.11.0 2016-02-15 17:29:24 Enter ".help" for usage hints.
Update port command:
sqlite> update servers set server_port=<CUSTOM UDP Port>;
Restart Teamspeak 3 server
robot00@apu00:~$ systemctl restart teamspeak.service
Test your connection using the <CUSTOM UDP Port>
Factorio Headless Setup
Resources:
- Multiplayer Factorio wiki
- Stable Factorio headless server
Check that your version of glibc is >= 2.18.
robot01@apu01:~$ ldd --version ldd (Ubuntu GLIBC 2.23-0ubuntu10) 2.23 Copyright (C) 2016 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. Written by Roland McGrath and Ulrich Drepper.
Output of ldd command confirms glibc version 2.23.
Switch to /opt directory and download latest Factorio stable headless version (0.16.36 as of this writing)
robot01@apu01:~$ cd /opt robot01@apu01:/opt$ sudo wget https://www.factorio.com/get-download/0.16.36/headless/linux64 ... ... ... Saving to: ‘linux64’ linux64 100%[==================================>] 23.04M 401KB/s in 2m 48s 2018-05-01 20:38:47 (141 KB/s) - ‘linux64’ saved [24163736/24163736]
Rename file to match version (0.16.36 in this example)
robot01@apu01:/opt$ sudo mv linux64 factorio_headless_x64_0.16.36.tar.xz
Extract archived and zipped file
robot01@apu01:/opt$ sudo tar -xJf factorio_headless_x64_0.16.36.tar.xz robot01@apu01:/opt$ ls -l total 47204 drwxr-xr-x 4 root root 4096 May 1 21:12 factorio -rw-r--r-- 1 factorio factorio 24163736 May 1 20:56 factorio_headless_x64_0.16.36.tar.xz
Remove file (save space, you can always download again if needed)
robot01@apu01:/opt$ sudo rm factorio_headless_x64_0.16.36.tar.xz
Add a new user to run factorio and assign ownership of /opt/factorio directory to same user
robot01@apu01:/opt$ sudo useradd factorio robot01@apu01:/opt$ sudo chown -R factorio:factorio /opt/factorio/
Verify permissions show factorio for both user and group
robot01@apu01:/opt$ ls -l total 4 drwxr-xr-x 4 factorio factorio 4096 May 1 21:12 factorio
Test Factorio binary by switching to factorio user then start server
robot01@apu01:/opt$ sudo su - factorio No directory, logging in with HOME=/ $
Start server and look for something like "File /savename does not exist."

As factorio user create /opt/factorio/ saves directory
$ mkdir /opt/factorio/saves
At this point you can load up saved games or create some games. Before that I want to install Factorio init script
Exit from factorio user back to sudo account
$ exit logout
Switch to /opt directory
robot01@apu01:/opt/factorio$ cd /opt
Clone Factorio init script from github
