Install

APISIX Installed and tested in the following systems:

OS	Status
CentOS 7	√
Ubuntu 18.04	√
Debian 9	√
CentOS 6	✘

You now have two ways to install APISIX: if you are using CentOS 7, it is recommended to use RPM, other systems please use Luarocks.

We will add support for Docker and more OS shortly.

Install from RPM for CentOS 7

sudo yum install yum-utils
sudo yum-config-manager --add-repo https://openresty.org/package/centos/openresty.repo
sudo yum install -y openresty etcd
sudo service etcd start

sudo yum install -y https://github.com/iresty/apisix/releases/download/v0.4/apisix-0.4-0.el7.noarch.rpm

You can try APISIX with the Quickstart now.

Install from Luarocks

Dependencies

APISIX is based on OpenResty, the configures data storage and distribution via etcd.

We recommend that you use luarocks to install APISIX, and for different operating systems have different dependencies, see more: Install Dependencies

Install APISIX

sudo luarocks install apisix

If all goes well, you will see the message like this:

apisix is now built and installed in /usr (license: Apache License 2.0)

Congratulations, you have already installed APISIX successfully.

Quickstart

1. start server:

sudo apisix start

2. try limit count plugin

For the convenience of testing, we set up a maximum of 2 visits in 60 seconds, and return 503 if the threshold is exceeded:

curl http://127.0.0.1:2379/v2/keys/apisix/routes/1 -X PUT -d value='
{
	"methods": ["GET"],
	"uri": "/index.html",
	"id": 1,
	"plugin_config": {
		"limit-count": {
			"count": 2,
			"time_window": 60,
			"rejected_code": 503,
			"key": "remote_addr"
		}
	},
	"upstream": {
		"type": "roundrobin",
		"nodes": {
			"39.97.63.215:80": 1
		}
	}
}'

Benchmark

Benchmark Environments

n1-highcpu-8 (8 vCPUs, 7.2 GB memory) on Google Cloud

But we only used 4 cores to run APISIX, and left 4 cores for system and wrk, which is the HTTP benchmarking tool.

Benchmark Test for reverse proxy

Only used APISIX as the reverse proxy server, with no logging, limit rate, or other plugins enabled, and the response size was 1KB.

QPS

The x-axis means the size of CPU core, and the y-axis is QPS.

Latency

Note the y-axis latency in microsecond(μs) not millisecond.

Flame Graph

The result of Flame Graph:

And if you want to run the benchmark test in your machine, you should run another Nginx to listen 80 port.

curl http://127.0.0.1:2379/v2/keys/apisix/routes/1 -X PUT -d value='
{
    "methods": ["GET"],
    "uri": "/hello",
    "id": 1,
    "plugin_config": {},
    "upstream": {
        "type": "roundrobin",
        "nodes": {
            "127.0.0.1:80": 1,
            "127.0.0.2:80": 1
        }
    }
}'

then run wrk:

wrk -d 60 --latency http://127.0.0.1:9080/hello

Benchmark Test for reverse proxy, enabled 2 plugins

Only used APISIX as the reverse proxy server, enabled the limit rate and prometheus plugins, and the response size was 1KB.

QPS

The x-axis means the size of CPU core, and the y-axis is QPS.

Latency

Note the y-axis latency in microsecond(μs) not millisecond.

            "127.0.0.2:80": 1
        }
    }
}'

then run wrk:

wrk -d 60 --latency http://127.0.0.1:9080/hello
