QPS 比 Kong 快10倍的开源网关-APISIX原创

# QPS 比 Kong 快10倍的开源网关-APISIX

Centos (opens new window) Docker (opens new window) APISIX (opens new window)

# APISIX 介绍

Apache APISIX 作为云原生架构的开源 API 网关，可以为海量 API 和微服务提供安全可靠的动态、高性能、可扩展的管理平台。 官网地址：https://apisix.apache.org/

# 架构

APISIX 分为Data Plane和Control Plane两个部分，Data Plane为提供API Gateway的端口，而Control Plane则时管理者进行日常配置的接口。

# 与kong 对比

APISIX 简介 (opens new window)

# apisix docker化部署

apisix 官方提供了apisix-docker (opens new window) 仓库，其中提供了Docker的构建和部署文件，但部署方法和说明不够明晰，特此写了此篇文档作以记录。

# 初始化系统及配置

为实现Docker数据变化的持久化，需要在容器宿主机的数据盘创建挂载目录。

# 数据持久化
mkdir -p /opt/data/apps/{apisix,etcd}
mkdir -p /opt/data/apps/etcd/data
chown -R 1001:1001 /opt/data/apps/etcd

# 创建自定义network
docker network create --driver bridge --subnet=172.18.1.0/24 --gateway=172.18.1.1 devops

# 由于apisix 的官方Docker镜像中并没有 config.yaml 文件，所以需要提前下载并配置。
# 下载 apisix 配置文件
# 源路径 https://github.com/apache/apisix-docker/blob/master/example/dashboard_conf/conf.yaml
wget https://www.nginxbar.com/scripts/apisix/apisix_conf.yaml -O /opt/data/apps/apisix/apisix_conf.yaml

# 下载 apisix Dahsboard 配置文件
# 源路径 https://github.com/apache/apisix-docker/tree/master/example/dashboard_conf
wget https://www.nginxbar.com/scripts/apisix/apisix_conf.yaml -O /opt/data/apps/apisix/apisix_conf.yaml

# 单机环境部署

APISIX 部署一共需要apisix、Dashboard、ectd 3个组件，apisix 为服务网关，Dashboard 为Web管理服务，Etcd 为存储。

# 修改apisix config etcd 地址
sed -i "s#http://etcd:2379#http://127.0.0.1:2379#g" /opt/data/apps/apisix/apisix_conf.yaml

# 修改apisix Dahboard config etcd 地址
sed -i "s#http://etcd:2379#http://127.0.0.1:2379#g" /opt/data/apps/apisix/dashboard_conf.yaml

# 集群环境部署

  • etcd 集群搭建 etcd IP 分别为172.85.0.10、172.85.0.11、172.85.0.12，分别在172.85.0.10、172.85.0.11、172.85.0.12 中执行如下shell 及docker-compose
mkdir -p /opt/data/apps/etcd/data
chown -R 1001:1001 /opt/data/apps/etcd

# 设定etcd 节点名，根据实际情况修改
echo "NODE_NAME=node2" >.env
# 设定etcd 集群节点名称
