Hi…
Kali ini kita akan coba reverse proxy pada apache2. Lab kali ini didasari dari tugas kantor (hahaha… lagi-lagi karena dapet tugas kantor).
Jadi dikantor sudah ada banyak web server, dengan IP berbeda-beda. Dan beberapa akan mempunyai subdomain yang dapat diakses dari internal kantor maupun dari public.
Topologinya kurang lebih seperti ini, masih menggunakan IP private. Nanti silahkan coba sendiri apabila ingin pasang IP Public
DNS server jadi satu dengan Router dimana menggunakan Mikrotik, dan sudah pernah dibahas disini.
Instalasi dan Seting Front Web Server
Update dan upgrade repository
[email protected]:/home/ubuntu#apt update && apt upgrade –y
Install apache2 dan build essential
[email protected]:/home/ubuntu#apt install build-essential apache2
Enable mod proxy untuk apache2
[email protected]:/home/ubuntu#a2enmod proxy proxy_http proxy_html
Set reverse proxy sub domain a.test.konfigurasi
Copy default.conf ke a.conf
[email protected]:/home/ubuntu#cd /etc/apache2/sites-available/ [email protected]:/etc/apache2/sites-available#cp 000-default.conf cacti.conf
Edit a.conf, sesuaikan dengan nama subdomain dan ip webserver
[email protected]:/etc/apache2/sites-available# nano a.conf <VirtualHost *:80> # The ServerName directive sets the request scheme, hostname and port t$ # the server uses to identify itself. This is used when creating # redirection URLs. In the context of virtual hosts, the ServerName # specifies what hostname must appear in the request's Host: header to # match this virtual host. For the default virtual host (this file) this # value is not decisive as it is used as a last resort host regardless. # However, you must set it for any further virtual host explicitly. ServerName a.test.konfigurasi ServerAdmin [email protected] #DocumentRoot /var/www/html # Available loglevels: trace8, ..., trace1, debug, info, notice, warn, # error, crit, alert, emerg. # It is also possible to configure the loglevel for particular # modules, e.g. #LogLevel info ssl:warn ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined ProxyPreserveHost On # Servers to proxy the connection, or # List of application servers Usage ProxyPass / http://192.168.192.2:80/ ProxyPassReverse / http://192.168.192.2:80/ # For most configuration files from conf-available/, which are # enabled or disabled at a global level, it is possible to # include a line for only one particular virtual host. For example the # following line enables the CGI configuration for this host only # after it has been globally disabled with "a2disconf". #Include conf-available/serve-cgi-bin.conf </VirtualHost> # vim: syntax=apache ts=4 sw=4 sts=4 sr noet
Ulangi langkah copy dan edit a.conf untuk b.conf dan c.conf, tentunya disesuaikan dengan nama subdomain dan IP masing-masing.
Selanjutnya, enable a.conf, b.conf dan c.conf
[email protected]:/etc/apache2/sites-available# a2ensite a.conf Enabling site a. To activate the new configuration, you need to run: service apache2 reload [email protected]:/etc/apache2/sites-available# a2ensite b.conf Enabling site b. To activate the new configuration, you need to run: service apache2 reload [email protected]:/etc/apache2/sites-available# a2ensite c.conf Enabling site c. To activate the new configuration, you need to run: service apache2 reload
Selanjutnya restart service apache
[email protected]:/etc/apache2/sites-available# service apache2 reload
Menambahkan subdomain pada Router/DNS Server
Setelah front dan backend web sudah siap, sekarang akan menambahkan atau pointing IP front web server ke masing-masing sub domain di Router MikroTik
Test ping dulu
