Continuing the journey of Web Server Application, today we would setup Nginx as Proxy Reverse. If you want to start with how to install Nginx and configure it with SSL/TLS, read here . This post scoped only in  CentOS  7 and I'm using  Alibaba Cloud  as my cloud provider. Using other Operating System (OS) or cloud provider may need some adjustment to be matched, but I'll describe in general. If you have a trouble during follow this tutorial, don't hesitate to ask in the comment. Let's dive in! Step 1 Run Go Application To make this tutorial simple, we gonna use go application to be proxy reverse by our Nginx. Since go application are binary, so they could directly running on our server without need to install any dependency. I have prepared the pre-compiled binary of go application that listen http request on port 8080 for linux OS. So let's download it (because we're not in administrative task, I recommend you to use normal user instead of root user). $...

Hello there, sorry for delay to post almost 2 months. Since covid-19 outbreak have significance impact to my working rhythm. Today I'll continue the journey of initial setup for CentOS 7. After securing our connection into the server (see here ), right now the most used application should we install is the Web Server. There are two most known, one is Nginx (read: Engine X) and Apache HTTP Server (also known as Apache WebServer or httpd ). Personally I recommend you to use Nginx instead of httpd , because the basic architecture of Nginx is using event-driven approach, instead of creating new thread for each request that doing in httpd . So Nginx could handle more concurrent request within small amount of threads. Also today, the event-driven approach are widely adopted, for example the famous ReactiveX library in the programming side is the leading asynchronous API library for programming languages. So more application are now evolved to use event-driven style instead of blockin...

Dalam keadaan default, apache2 akan berjalan pada port 80, yaitu port dimana protokol http biasanya diakses. Namun bagaimanakah kita bisa memanfaatkan port lain agar apache2 ini bisa berjalan pada port selain port defaultnya?? Saya akan membahas di sini bagaimana agar apache2 bisa berjalan pada port selain 80. Pertanyaan mendasarnya adalah, mengapa kita harus mengubah port default dari apache2 ini?? Untuk kebutuhan-kebutuhan khusus, mungkin anda akan sangat membutuhkan untuk menjalankan apache2 pada port lain. Semisal suatu kasus, saya telah berhasil mendapatkan hak akses administrator router dari sebuah jaringan lokal (LAN), selain melakukan aktivitas hacking di dalam jaringan lokal tersebut, saya juga ingin melakukan aktivitas hacking yang berinteraksi dengan internet, misalkan suatu server yang juga terhubung ke jaringan internet. Sehingga saya butuh port forwarding pada router tersebut untuk menggunakan IP Publiknya, sementara port 80 telah dipakai oleh komputer lain, sehingga...
