How to monitor server running in Android phone?

This video shows how to monitor android with Trafikito :)

React Native. How change package name for Android?

Make sure android>app>build.gradle

defaultConfig {
applicationId "WHATEVER_THIS_IS"
}
needs to match android>app>src>main>java>com>app_name>MainActivity.java line one:

package WHATEVER_THIS_IS;
needs to match android>app>src>main>java>com>app_name>MainApplication.java line one:

package WHATEVER_THIS_IS;
needs to match android>app>src>AndroidManifest.xml

package="WHATEVER_THIS_IS">

-----

android/app/src/main/java/com/PROJECT_NAME/MainActivity.java:

package MY.APP.ID;

In android/app/src/main/java/com/PROJECT_NAME/MainApplication.java:

package MY.APP.ID;

In android/app/src/main/AndroidManifest.xml:

package="MY.APP.ID"

And in android/app/build.gradle:

applicationId "MY.APP.ID"

todo after fresh ubuntu server vps install

apt-get install nano -y

echo "export LC_ALL=en_US.UTF-8" >> ~/.bashrc
echo "export LANG=en_US.UTF-8" >> ~/.bashrc
echo "export LANGUAGE=en_US.UTF-8" >> ~/.bashrc
echo "export LC_ALL=en_US.UTF-8" >> ~/.profile
echo "export LANG=en_US.UTF-8" >> ~/.profile
echo "export LANGUAGE=en_US.UTF-8" >> ~/.profile

sudo locale-gen "en_US.UTF-8"
sudo dpkg-reconfigure locales

apt-get install htop

How i fix local issues on my ubuntu server

put these lines in your ~/.bashrc and ~/.profile files:

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
export LANGUAGE=en_US.UTF-8

reboot 1 // can be re-login but reboot is so fast for my vps servers that i just reboot lol, less typing :)

sudo locale-gen "en_US.UTF-8"
sudo dpkg-reconfigure locales

How i did SSL with let's encrypt for free

I use ubuntu v14 on vps machine. I have couple nodejs scripts running with pm2. I use https server inside js files:

const app = require('express')();

const fs = require('fs');
var privateKey = fs.readFileSync('/etc/letsencrypt/live/domain.com/privkey.pem'); // privatekey.pem

var certificate = fs.readFileSync('/etc/letsencrypt/live/domain.com/cert.pem'); // certificate.pem

var chain = fs.readFileSync('/etc/letsencrypt/live/domain.com/fullchain.pem'); // certificate.pem
const https = require('https').Server({
  key: privateKey,
  cert: certificate,
  ca: chain}, app);

In nginx i use this:

server {

listen 443 ssl;

server_name domain.com www.domain.com;

ssl_certificate /etc/letsencrypt/live/domain.com/fullchain.pem;

ssl_certificate_key /etc/letsencrypt/live/domain.com/privkey.pem;

keepalive_timeout 10;

location /.well-known/acme-challenge/ {

alias /var/www/challenges/;

try_files $uri =404;

}

location / {

proxy_redirect off;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_set_header X-Forwarded-Proto $scheme;

proxy_set_header Host $http_host;

proxy_set_header X-NginX-Proxy true;

proxy_set_header Connection "";

proxy_pass http://pm2upstream;

}

Tried different guides and failed.

This worked:

wget https://dl.eff.org/certbot-auto
chmod a+x ./certbot-auto
service nginx stop
./certbot-auto certonly & follow instructions, use auto server
reboot 0 // i hear you screaming about this, best wishes, sys admins
