docker-compose nacos单主机集群搭建教程

1.创建数据库

使用Navicat 连接 MySQL，创建数据库nacos_config
下载 Nacos官方安装包nacos-server-2.2.0.zip或者nacos-server-2.2.0.tar.gz，找到 conf/mysql-schema.sql脚本，导入 nacos_config 数据库

2. 创建目录

mkdir-p/data/nacos-cluster

mkdir-p/data/nacos-cluster/nacos1/{conf,logs,data}/data/nacos-cluster/nacos2/{conf,logs,data}/data/nacos-cluster/nacos3/{conf,logs,data}

3. 创建application.properties

在/data/nacos-cluster/nacos1/conf下创建application.properties文件，内容如下，并复制到/data/nacos-cluster/nacos2/conf和/data/nacos-cluster/nacos3/conf下

# 数据库配置spring.datasource.platform=mysqldb.num=1db.url.0=jdbc:mysql://主机ip:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false&serverTimezone=Asia/Shanghaidb.user=rootdb.password=数据库密码# 集群节点列表nacos.cluster.members=主机ip:8848,主机ip:8849,主机ip:8850# 本机IP（必须写宿主机内网IP，不能127.0.0.1）nacos.inetutils.ip-address=主机ip

4. 创建docker-compose.yml

在/data/nacos-cluster目录下新建docker-compose.yml文件，内容如下：

version:"3.8"services: nacos1: image: nacos/nacos-server:v2.2.0 container_name: nacos1 restart: always ports: -"8848:8848"-"9848:9848"-"7848:7848"volumes: - ./nacos1/conf/application.properties:/home/nacos/conf/application.properties - ./nacos1/logs:/home/nacos/logs - ./nacos1/data:/home/nacos/data environment: -MODE=cluster -PREFER_HOST_MODE=hostname networks: nacos_net: aliases: - nacos1 nacos2: image: nacos/nacos-server:v2.2.0 container_name: nacos2 restart: always ports: -"8849:8848"-"9849:9848"-"7849:7848"volumes: - ./nacos2/conf/application.properties:/home/nacos/conf/application.properties - ./nacos2/logs:/home/nacos/logs - ./nacos2/data:/home/nacos/data environment: -MODE=cluster -PREFER_HOST_MODE=hostname networks: nacos_net: aliases: - nacos2 nacos3: image: nacos/nacos-server:v2.2.0 container_name: nacos3 restart: always ports: -"8850:8848"-"9850:9848"-"7850:7848"volumes: - ./nacos3/conf/application.properties:/home/nacos/conf/application.properties - ./nacos3/logs:/home/nacos/logs - ./nacos3/data:/home/nacos/data environment: -MODE=cluster -PREFER_HOST_MODE=hostname networks: nacos_net: aliases: - nacos3 networks: nacos_net: driver: bridge
