Siapkan SSH dan Script Deploy

SSH tanpa password

sebelum membuat script deply.bat kita pastikan dulu ssh kita tanpa password. Sehingga tidak perlu memasukkan password setiap kali menjalankan script deploy.
Using git bash create yout key, you dont have to do this if you already have a key

ssh-keygen -t rsa -b 4096 -C "rolly@awang.ga"

send key to the server

cat ~/.ssh/id_rsa.pub | ssh -p 123 usernya@hostnya.com 'cat >> .ssh/authorized_keys'

ssh into server and change permission

chmod 700 .ssh; chmod 640 .ssh/authorized_keys

Script Deploy

script deploy jika pada saat go mod init bernama api

$env:GOOS = 'linux'
$env:CGO_ENABLED = '1'
go build
scp -P 123 api user@domain:/root/apinew
ssh -p 123 user@domain chmod +x /root/apinew
ssh -p 123 user@domain ls -l
ssh -p 123 user@domain systemctl status api
ssh -p 123 user@domain systemctl stop api
ssh -p 123 user@domain systemctl status api
ssh -p 123 user@domain mv /root/apinew /root/api
ssh -p 123 user@domain systemctl start api
ssh -p 123 user@domain systemctl status api

Deploy Binary on Web Hosting

Buat dulu folder dan chmod folder tersebut ke 755

chmod -R 755 namafolder

buat file run.sh dan stop.sh file. run.sh file

#!/bin/bash

if ! pgrep -f 'binary_app'
then
    nohup /home/file_path/binary_app && echo "baru running" > ./out_test.txt
else
    echo "udah di-run" > ./out_test.txt
fi

stop.sh file

#!/bin/bash

if pgrep -f 'binary_app'
then
    pgrep -f 'binary_app' | xargs kill &&  echo "baru stop" > ./out_test.txt
else
    echo "udah di-stop" > ./out.txt
fi

pastikan dua file tersebut bisa di eksekusi dengan perintah chmod

chmod a+x run.sh stop.sh

buat .htaccess file di dalam folder

Options +FollowSymLinks -Indexes
IndexIgnore *
DirectoryIndex
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteRule ^(.*)$ http://127.0.0.1:8080/api/$1 [P]
</IfModule>
