NEM Nis install script for Centos 7/Ubuntu 1604 (only for testing!)

SirNembalot · March 12, 2018, 8:44am

Hi all,

Finally finalized the install script that automatically installs NEM Nis to Centos 7. Script is first version and should be treated as such. I have ran it multiple times successfully on freshly installed Centos 7, so it should work BUT there might be some things I have not noticed. Required programs for this script: unzip, java and curl.

Please DO NOT run this yet on production server, I still need to check and verify that needed checks are in place so that it wont accidentally break anything. Also, it wont check integrity of downloaded files - I might add that option later, but then one must install more programs before running the script.

As always, I am open for any comments and feedback.

Disclaimer: script is fan made, DEVs or Admins have not checked it! Treat it as such! No warranties!

You have been warned. Script can be found from:

github.com

#!/bin/bash
#
# Description: Install script to install NEM Infrastuctrure Server on Centos 7. Will also bootstrap, 
#              set log cleaning and add possibility to control NIS using Centos/Ubuntu systemtools (systemctl)
# Details:
# * Creates user "nemnis" (system account, no login, no password)
# * Creates service "nemnis" for OS (control with systemctl command)
# * Downloads latest NIS and bootstrap file
# * Uses /opt/nemnis as home directory, creates symlink nis_latest and is referred in systemctl conf file
# * NIS configuration (config-user.properties) in /opt/nemnis/nem directory => no need to update/replace/reconfigure 
#   configuration when NIS is updated (though, you need to check for possible new params)
# * Places simple logrotate script to cron daily
# * Creates configuration file for Centos firewall (allows port 7890 in) OR allows port 7890 in on Ubuntu (ufw)

# NIS upgrade (example number only!, also "nemnis" might be different if you changed user from script):
# tar xzf nis-0.7.70.tgz -C /opt/nemnis
# mkdir /opt/nemnis/nis-0.7.70
# mv /opt/nemnis/package/* /opt/nemnis/nis-0.7.70
# rm -rf /opt/nemnis/nis_latest
# ln -s /opt/nemnis/nis-0.7.70 /opt/nemnis/nis_latest

Update: changed filename because script now supports Centos 7 and Ubuntu 1604.

Nice job!

Thank you @kodtycoon

I updated the script; checks/tests are made at beginning of script (before any changes/commits), more tests and script can be run on Centos 7 and Ubuntu 16.04, also changes systemd service name to “nemnis” due to conflict.

@SirNembalot using your systemd service, don’t you get duplicate logs? Since systemd creates it’s own logs…
