如何构建 Apache APISIX

注：此文档构建环境为腾讯云CentOS7.9，虚拟机同样适用。

步骤1：安装依赖

# 编写依赖脚本
cd /usr/local && mkdir apisix-deps
cd apisix-deps && vim deps.sh
# 脚本内容见下方代码块
# 添加权限并执行脚本，安装依赖
chmod +x deps.sh && ./deps.sh
rm -f deps.sh

#!/usr/bin/env bash

步骤2：安装 Apache APISIX

通过源码包安装

  1. 创建一个名为 apisix-2.11.0 的目录。

    cd /usr/local && mkdir apisix-2.11.0 && cd apisix-2.11.0

  2. 下载 Apache APISIX Release 源码包：

    yum install -y wget && wget https://downloads.apache.org/apisix/2.11.0/apache-apisix-2.11.0-src.tgz

    您也可以通过 Apache APISIX 官网下载 Apache APISIX Release 源码包。 Apache APISIX 官网也提供了 Apache APISIX、APISIX Dashboard 和 APISIX Ingress Controller 的源码包，详情请参考Apache APISIX 官网-下载页。

  3. 解压 Apache APISIX Release 源码包：

    tar zxvf apache-apisix-2.11.0-src.tgz -C /usr/local/apisix-2.11.0 && rm -f apache-apisix-2.11.0-src.tgz

  4. 安装运行时依赖的 Lua 库：

    # 安装依赖
LUAROCKS_SERVER=https://luarocks.cn make deps
# 安装 apisix 命令
make install

步骤3：管理 Apache APISIX 服务

我们可以在 Apache APISIX 的目录下使用命令初始化依赖、启动服务和停止服务，也可以通过 apisix help 命令查看所有命令和对应的功能。

初始化依赖

运行以下命令初始化 NGINX 配置文件和 etcd。

# initialize NGINX config file and etcdapisix init
apisix init

启动 Apache APISIX

运行以下命令启动 Apache APISIX。

# start Apache APISIX serverapisix start
apisix start

停止运行 Apache APISIX

优雅停机 apisix quit 和强制停机 apisix stop都可以停止运行 Apache APISIX。建议您优先选择优雅停机的方式停止 Apache APISIX，因为这种停止方式能够保证 Apache APISIX 完成了已经接受到的请求之后再停止；而强制停机则是立即停止 Apache APISIX，在这种情况下，Apache APISIX 接收到但未完成的请求会随着强制停机一并停止。

执行优雅停机的命令如下所示：

# stop Apache APISIX server gracefully
apisix quit

执行强制停机的命令如下所示：

# stop Apache APISIX server immediately
apisix stop

查看其他操作

运行 apisix help 命令，查看返回结果，获取其他操作的命令和描述。

# more actions find by `help`
apisix help

步骤4：修改 Admin API key

您需要修改 Admin API 的 key，以保护 Apache APISIX。

请修改 conf/config.yaml 中的 apisix.admin_key 并重启服务，如下所示：

apisix:
  # ... ...
  admin_key
    -
      name: "admin"
      key: lileihehanmeimei # 将原有的 key 修改为abcdefghabcdefgh
      role: admin

当我们需要访问 Admin API 时，就可以使用上面记录的 key 了，如下所示：

curl http://127.0.0.1:9080/apisix/admin/routes?api_key=lileihehanmeimei -i

返回结果中的状态码 200 说明访问成功，如下所示：

HTTP/1.1 200 OK
Date: Wed, 15 Dec 2021 08:40:30 GMT
Content-Type: application/json
Transfer-Encoding: chunked
Connection: keep-alive
Server: APISIX/2.11.0
Access-Control-Allow-Origin: *
Access-Control-Allow-Credentials: true
Access-Control-Expose-Headers: *
Access-Control-Max-Age: 3600

{"node":{"nodes":{},"dir":true,"key":"\/apisix\/routes"},"action":"get","count":0}

在这个时候，如果您输入的 key 与 conf/config.yaml 中 apisix.admin_key 的值不匹配，例如，我们已知正确的 key 是 lileihehanmeimei，但是我们选择输入一个错误的 key，例如 wrong-key，如下所示：

curl http://127.0.0.1:9080/apisix/admin/routes?api_key=wrong-key -i

返回结果中的状态码 401 说明访问失败，原因是输入的 key 有误，未通过认证，触发 Unauthorized 错误，如下所示：

HTTP/1.1 401 Unauthorized
Date: Wed, 15 Dec 2021 08:41:10 GMT
Content-Type: application/json
Transfer-Encoding: chunked
Connection: keep-alive
Server: APISIX/2.11.0
Access-Control-Allow-Origin: *
Access-Control-Allow-Credentials: true
Access-Control-Expose-Headers: *
Access-Control-Max-Age: 3600

{"error_msg":"failed to check token"}
