Loading... # 使用docker 搭建 Nacos 发现和配置服务 ### Nacos的搭建 - 可使用官网的release直接启动,这里参照[官方教程](https://nacos.io/zh-cn/docs/quick-start.html)就行 - 考虑到会用到很多中间件,一个个安装非常麻烦,所以使用docker-compose一把梭 - nacos有两种数据存储方式,自建的Derby或MySQL,很明显前者不适合生产,所以这里使用mysql 文件夹结构 ![结构](https://i.imgur.com/i7Wvj5A.png) - `.\mysql\conf.d`: mysql配置文件 ```plain [client] default-character-set=utf8mb4 [mysql] default-character-set=utf8mb4 [mysqld] skip-host-cache skip-name-resolve default-authentication-plugin=mysql_native_password sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION table_open_cache=512 character-set-server=utf8mb4 collation-server=utf8mb4_general_ci default-time-zone='+8:00' log-bin=mysql-binlog binlog-format=ROW server_id=1 max_connections=1000 max_user_connections=1000 mysqlx_max_connections=1000 thread_cache_size=64 ``` - `.\mysql\initdb`: 初始化数据库,这里使用的官方的sql,添加了创建数据库的步骤,请参考[官方仓库](https://github.com/nacos-group/nacos-docker/tree/master/example),这边的数据库名称随意改,只要你连的上就行 ```sql /* * Copyright 1999-2018 Alibaba Group Holding Ltd. * * Licensed under the Apache License, Version 2.0 (the "License");

``` - `docker-compose.yaml`: docker-compose的启动文件,启动单机模式的nacos,实际生产中请使用集群模式,sql至少是主备模式 ```yaml version: "3.8" services: store-mysql: image: mysql:8.0.35 container_name: store-mysql restart: always environment: - MYSQL_ROOT_PASSWORD=password # 注意端口占用,若出现mysql启动报错更改前面的3306即可,nacos无需更改,因为使用的容器之间的网络 ports: - "3306:3306" volumes: - ./mysql/data:/var/lib/mysql - ./mysql/conf.d:/etc/mysql/conf.d - ./mysql/initdb:/docker-entrypoint-initdb.d networks: - "nacos_network" store-nacos: image: nacos/nacos-server:v2.2.3-slim container_name: store-nacos restart: always depends_on: - store-mysql ports: - "8848:8848" - "9848:9848" - "9849:9849" environment: - JVM_XMS=256m - JVM_XMX=512m - MODE=standalone - PREFER_HOST_MODE=hostname - SPRING_DATASOURCE_PLATFORM=mysql # 注意一下这边的host应该填写容器名称(推荐)或宿主机ip - MYSQL_SERVICE_HOST=store-mysql - MYSQL_SERVICE_DB_NAME=store_cloud_nacos - MYSQL_SERVICE_USER=root - MYSQL_SERVICE_PASSWORD=password - MYSQL_SERVICE_DB_PARAM=characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false&allowPublicKeyRetrieval=true volumes: - ./nacos/logs:/home/nacos/logs networks: - "nacos_network" networks: nacos_network: driver: bridge ``` > 这边官方文档写的挺简单的,但坑不少,我在MYSQL_SERVICE_HOST这个变量上填写宿主ip,nacos会报错no datasource set并自动销毁重启,使用docker容器间通信的写法才正常 > 接下来启动即可 ```shell docker-compose up -d ``` 关闭 ```shell docker-compose stop ``` 销毁 ```shell docker-compose down ``` ### Nacos修改鉴权 官方文档:https://nacos.io/zh-cn/docs/auth.html 不知道为何配置了环境变量无法生效,所以直接修改容器 ```shell docker exec -it <刚刚创建的nacos容器id> /bin/bash # 这里可能先要安装vim,执行 apt install vim 即可 vim /home/nacos/conf/application.properties ``` 找到这几行并替换 ```properties ### The auth system to use, currently only 'nacos' and 'ldap' is supported: ### 添加nacos.core.auth.enabled=true nacos.core.auth.system.type=${NACOS_AUTH_SYSTEM_TYPE:nacos} nacos.core.auth.enabled=true ### worked when nacos.core.auth.system.type=nacos ### The token expiration in seconds: nacos.core.auth.plugin.nacos.token.expire.seconds=${NACOS_AUTH_TOKEN_EXPIRE_SECONDS:18000} ### The default token: ### 这里默认为空(v2.2.0版本后) nacos.core.auth.plugin.nacos.token.secret.key=${NACOS_AUTH_TOKEN:SecretKey012345678901234567890123456789012345678901234567890123456789} ### Turn on/off caching of auth information. By turning on this switch, the update of auth information would have a 15 seconds delay. ### 启用缓存,具体说明请查看官方文档 nacos.core.auth.caching.enabled=${NACOS_AUTH_CACHE_ENABLE:true} nacos.core.auth.enable.userAgentAuthWhite=${NACOS_AUTH_USER_AGENT_AUTH_WHITE_ENABLE:false} nacos.core.auth.server.identity.key=${NACOS_AUTH_IDENTITY_KEY:nacos} nacos.core.auth.server.identity.value=${NACOS_AUTH_IDENTITY_VALUE:nacos} ``` 最后修改:2023 年 11 月 13 日 © 允许规范转载 打赏 赞赏作者 支付宝微信 赞 如果觉得我的文章对你有用,请随意赞赏
