+环境准备:
+1. 安装 docker
+2. 安装 goland，会在 goland 中启动 server、pixiu、test
+
+结构图:
+见 farconfnacos.png
+
+案例运行步骤:
+1. 在 docker 中启动 zk 和 nacos. 其中 zk 作为配置中心；nacos 作为远端配置中心，存储 pixiu 的启动参数
+2. 在 nacos 中创建配置，配置内容为 farconfnacos/nacos 目录中文件
+3. 设置命令行参数，启动 dubbogo server:
+- Working directory:
+- D:\mongo\samples\dubbogo\simple\farconfnacos\server
+
+- Environment:
+- APP_LOG_CONF_FILE=./profiles/dev/log.yml;DUBBO_GO_CONFIG_PATH=./profiles/dev/server.yml
+
+4. 设置命令行参数，启动 pixiu:
+- Package path:
+- github.com/apache/dubbo-go-pixiu/cmd/pixiu
+
+- Working directory:
+- D:/mongo/dubbo-go-pixiu-develop
+
+- Program arguments:
+- gateway start -c D:\mongo\dubbo-go-pixiu-samples\dubbogo\simple\farconfnacos\pixiu\conf.yaml
+
+5. 运行 test，查看结果
