docker部署standalone模式單獨啓動nacos

一. 概述

關於這個nacos是幹什麼用的，怎麼用，在這裏就不多說了，可以直接查看官網的相關資料，這裏主要說明的是docker部署啓動nacos。當然官網頁有資料說明怎麼使用docker啓動nacos，但是感覺官網的好繁瑣。

二. 準備

1> 數據庫

由於nacos的配置數據等等都是存放在數據庫，nacos本身也是依賴數據庫的，所以我們首先要準備數據庫。數據庫的準備可以查看mysql文件夾資料或者數據庫的主從創建資源。我這裏使用的是主從數據庫，當然也是可以使用單個數據庫的。然後就是創建數據庫和表格。

創建數據庫

CREATE DATABASE dawn_nacos

數據庫下創建表（也可以去官網查找sql文件）

2> docker下載nacos鏡像

docker pull nacos/nacos-server

3> 準備文件目錄

在linux下創建這樣的目錄（這是我自己的）：

/home/docker/nacos/standalone

4> 準備standlone-nacos.yml文件

version: '3.1'
services:
  nacos:
    image: nacos/nacos-server:1.1.3
    container_name: nacos-standalone-server
    environment:
      - PREFER_HOST_MODE=hostname
      #模式爲單體模式
      - MODE=standalone
      - SPRING_DATASOURCE_PLATFORM=mysql
      # 我的主數據
      - MYSQL_MASTER_SERVICE_HOST=192.168.47.150
      - MYSQL_MASTER_SERVICE_DB_NAME=dawn_nacos
      - MYSQL_MASTER_SERVICE_PORT=3306
      # 我的從數據庫
      - MYSQL_SLAVE_SERVICE_HOST=192.168.47.150
      - MYSQL_SLAVE_SERVICE_PORT=3307
      - MYSQL_MASTER_SERVICE_USER=root
      - MYSQL_MASTER_SERVICE_PASSWORD=wszgr
    volumes:
      # 日誌地址映射
      - ./logs/:/home/nacos/logs
      # 配置文件，這個需要自己準備，如果開啓監控還需要配置裏面的一些東西，這裏暫時不配置
      - ./properties/custom.properties:/home/nacos/init.d/custom.properties
    ports:
      - "8848:8848"
    restart: on-failure

將該文件放在/home/docker/nacos/standalone目錄下

5> 準備custom.properties文件（上面數據卷映射）

這個可以去官網查找下載，也可以直接使用我的，我就是從官網下載的：

#spring.security.enabled=false
#management.security=false
#security.basic.enabled=false
#nacos.security.ignore.urls=/**
#management.metrics.export.elastic.host=http://localhost:9200
# metrics for prometheus
#management.endpoints.web.exposure.include=*

# metrics for elastic search
#management.metrics.export.elastic.enabled=false
#management.metrics.export.elastic.host=http://localhost:9200

# metrics for influx
#management.metrics.export.influx.enabled=false
#management.metrics.export.influx.db=springboot
#management.metrics.export.influx.uri=http://localhost:8086
#management.metrics.export.influx.auto-create-db=true
#management.metrics.export.influx.consistency=one
#management.metrics.export.influx.compressed=true

將該文件放在/home/docker/nacos/standalone/properties目錄下

三. 啓動

進入到/home/docker/nacos/standalone目錄下，執行以下命令：

docker-compose -f standalone-nacos.yml up -d

在這裏我遇到了2個問題，我來分別簡單的說一下：

1> iptables failed

具體如下：

通過對網上資料的瞭解，是由於breidge模式下的docker創建了一個docker0的虛擬網橋，主要是用於宿主機和容器之間的通信，當容器以bridge方式啓動的時候，docker容器就會附加到虛擬網橋上面。而我們對防火牆之類的網絡相關文件操作的時候可能導致這個虛擬網橋失效，所以我們只需要重啓docker便可：

systemctl restart docker

這樣就會重新創建虛擬網橋。

2> NoRouteToHostException: No route to host

這個意思是無法路由到主機異常，而且這個錯誤出來的時候，通常都伴隨着無法連接到數據庫，也就導致了nacos啓動失敗了。導致這個異常的原因是容器無法連接到宿主機的指定端口造成的。解決方案是：

關閉宿主機的防火牆
在宿主機的防火牆上開發指定的端口（我們這裏是3306和3307）

關於這兩個問題的詳細內容查看筆記的docker問題文件夾下內容或者訪問容器無法訪問宿主機報出 No route to host

四. 測試

打開網頁測試連接 http://192.168.47.150:8848/nacos (這是我的虛擬機，你自己按自己的來)

docker部署standalone模式單獨啓動nacos

一. 概述

二. 準備

1> 數據庫

2> docker下載nacos鏡像

3> 準備文件目錄

4> 準備standlone-nacos.yml文件

5> 準備custom.properties文件（上面數據卷映射）

三. 啓動

1> iptables failed

2> NoRouteToHostException: No route to host
