Creating a backup

Use pg:backups:capture to create a backup.

➜  heroku pg:backups:capture --app staging-gtds
Starting backup of postgresql-spherical-26253... done

Use Ctrl-C at any time to stop monitoring progress; the backup will continue running.
Use heroku pg:backups:info to check progress.
Stop a running backup with heroku pg:backups:cancel.

chmod digunakan untuk mengganti permission dari sebuah file atau folder. setiap file dapat diakses 3 pengguna, yaitu user (u), group (g) and others (o).

contoh:

➜  test ls -l
total 0
-rw-rw-r-- 1 omz omz 0 Jun 19 08:04 test1
-rw-rw-r-- 1 omz omz 0 Jun 19 08:04 test2
-rw-rw-r-- 1 omz omz 0 Jun 19 08:04 test3

Creating a Deploy user

Create a new user named deploy with a home directory of /opt/deploy:

sudo adduser deploy --home /opt/deploy

add user deploy to the sudo group.

adduser deploy sudo

Login to the server

Type this command: (make sure the pem file location is correct)

ssh -i "imeducate-client.pem" [email protected]

Install Ruby

Since rvm is already installed, then just install ruby 2.5.8:

Create a new user named deploy with a home directory of /opt/deploy:

useradd -m -d /opt/deploy deploy
or
adduser deploy --home /opt/deploy

Create the deploy user and add them to the sudo group.

Saya mendapatkan kesempatan update aplikasi Rails 4 ke Rails 6. Semua lancar jaya ketika di mesin development. Kemudian saya mendeploy aplikasi tersebut ke server dan mendapatkan error berikut:

ActionView::Template::Error (uninitialized constant SubscriptionsMixin::Subscriptioxxxxx
Did you mean?  SubscriptionsMixin):
    1: .purchase-details
    2:   = semantic_form_for [ line_item ], namespace: form_namespace do |f|
    3:     = f.inputs do
    4:       = f.input :duration_in_months, as: :select, collection: product.member_trial_options_for_select(current_member) + product.subscription_options_for_select, include_blank: false, label: label
 5: = f.input :product_id, as: :hidden, input_html: { value: product.id }

Backup the database:

pg_dump -U imeducate imeducate_production -f imeducate_production.sql -h localhost

Install Postgres 9.5

wget https://gist.github.com/petere/5893799/raw/d1b3a4a7e92e397e2c323ca9ce93ec958dcf6474/apt.postgresql.org.sh
chmod a+x apt.postgresql.org.sh

Copy the following script and save it in your server as rabbit.sh:

#!/bin/sh
## If sudo is not available on the system,
## uncomment the line below to install it
# apt-get install -y sudo
sudo apt-get update -y
## Install prerequisites
sudo apt-get install curl gnupg -y
