+# Haproxy setup 
+
+This one is done from proxmox, i used a debian10+ CT template to create the machines i needed.
+
+## **Initial setup**
+
+To start with, get 2 identical debian hosts with nginx on them:

+
+My 2 servers will have the ips 192.168.0.151 and 192.168.0.150 meanwhile 192.168.0.152 is going to be our haproxy server.
+
+_First server:_
+    
+    
+    apt update -y && apt upgrade -y
+    apt install nginx curl -y
+    echo 'server number 1' > /var/www/html/index.nginx-debian.html
+    ip a | grep inet	#IP1
+    
+    
+
+![](2.png) _Second server:_
+    
+    
+    apt update -y && apt upgrade -y
+    apt install nginx curl -y
+    echo 'server number 2 ' > /var/www/html/index.nginx-debian.html
+    ip a | grep inet	#IP2
+    
+    
+

+
+Now that we have 2 servers running http, we're going to load balance them with a third debian machine with haproxy:
+    
+    
+    apt update -y  && apt upgrade -y
+    apt install haproxy curl -y
+    wget https://blog.nowhere.moe/servers/haproxy/haproxy.cfg -O /etc/haproxy/haproxy.cfg
+    nano /etc/haproxy/haproxy.cfg 
+    systemctl restart haproxy
+    ip a | grep inet	#IP3
+    curl 127.0.0.1
+    
+    
+
+In nano, change the ips with the ips of your 2 debian servers (IP1 & IP2) and reload haproxy, then go and see if haproxy works (IP3)

+
+You can reload haproxy's webpage multiple times, and you'll see that sometimes it is going to switch from one server to the other, therefore we successfully setup a simple load balancing with haproxy.
