Orange 简介
Orange是一个基于OpenResty的API网关。除Nginx的基本功能外，它还可用于API监控、访问控制(鉴权、WAF)、流量筛选、访问限速、AB测试、动态分流等。它有以下特性：
- 提供了一套默认的Dashboard用于动态管理各种功能和配置
- 提供了API接口用于实现第三方服务(如个性化运维需求、第三方Dashboard等)
- 可根据规范编写自定义插件扩展Orange功能

配置文件
[Orange有两个配置文件，一个是conf/orange.conf，用于配置插件、存储方式和内部集成的默认Dashboard，另一个是conf/nginx.conf用于配置Nginx(OpenResty).]
- orange.conf的配置如下，请按需修改:
{
"plugins": [ //可用的插件列表，若不需要可从中删除，系统将自动加载这些插件的开放API并在7777端口暴露
"stat",
"monitor",
"redirect",
"rewrite",
"rate_limiting",
"property_rate_limiting",
"basic_auth",
"key_auth",
"signature_auth",
"waf",
"divide",
"kvstore"
],
"store": "mysql",//目前仅支持mysql存储
"store_mysql": { //MySQL配置
"timeout": 5000,
"connect_config": {//连接信息，请修改为需要的配置
"host": "localhost", // 注意修改修改为本地数据库信息
"port": 3306, // 注意修改修改为本地数据库信息
"database": "orange", // 注意修改修改为本地数据库信息
"user": "root", // 注意修改修改为本地数据库信息
"password": "123", // 注意修改修改为本地数据库信息
"max_packet_size": 1048576
},
"pool_config": {
"max_idle_timeout": 10000,
"pool_size": 3
},
"desc": "mysql configuration"
},
"dashboard": {//默认的Dashboard配置.
"auth": false, //设为true，则需用户名、密码才能登录Dashboard,默认的用户名和密码为admin/orange_admin
"session_secret": "y0ji4pdj61aaf3f11c2e65cd2263d3e7e5", //加密cookie用的盐，自行修改即可
"whitelist": [//不需要鉴权的uri，如登录页面，无需修改此值
"^/auth/login$",
"^/error/$"
]
},
"api": {//API server配置
"auth_enable": true,//访问API时是否需要授权
"credentials": [//HTTP Basic Auth配置，仅在开启auth_enable时有效，自行添加或修改即可
{
"username":"api_username",
"password":"api_password"
}
]
}
}- conf/nginx.conf里是一些nginx相关配置，请自行检查并按照实际需要更改或添加配置，特别注意以下几个配置：
- lua_package_path：需要根据本地环境配置适当修改，如lor框架的安装路径
- resolver：DNS解析
- 各个server或是location的权限，如是否需要通过allow/deny指定配置黑白名单ip
数据表导入MySQL
- 在MySQL中创建数据库，名为orange
