tinybalancer
tinybalancer is a reverse proxy load balancer that supports http and https. It currently supports five algorithms, namely round-robin, random, the power of 2 random choice, consistent hash and consistent hash with bounded.
Install
First download the source code of balancer:
> git clone https://github.com/zehuamama/tinybalancer.git
compile the source code:
> cd ./tinybalancer
> go build
Run
Balancer needs to configure the config.yaml file, the content is as follows:

# The load balancing algorithms supported by the balancer are:
# `round-robin` ,`random` ,`p2c`,`consistent-hash`,`bounded`,
# Among these,`p2c` refers to the power of 2 random choice,
# and `bounded` refers to consistent hash with bounded
schema: http # support http and https
port: 8089 # port for balancer
ssl_certificate:
ssl_certificate_key:
location: # route matching for reverse proxy

proxy_pass: # URL of the reverse proxy
- "http://127.0.0.1:1012"
- "http://127.0.0.1:1013"
balance_mode: round-robin # load balancing algorithm
and now, you can execute tinybalancer, the balancer will print the ascii diagram and configuration details:
> ./tinybalancer
