配置配置

创建目录

mkdir -p data/cluster-logs/nacos1;
mkdir -p data/cluster-logs/nacos2;
mkdir -p data/cluster-logs/nacos3;
mkdir -p data/init.d;
mkdir -p env/;

配置custom.properties

        在data/init.d目录下配置custom.properties文件。

#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

配置nacos配置信息

        在env目录下配置nacos-hostname.env，MYSQL_SERVICE_HOST中填写当前服务对应的ip。

#nacos dev env
PREFER_HOST_MODE=hostname
NACOS_SERVERS=nacos1:8848 nacos2:8848 nacos3:8848
MYSQL_SERVICE_HOST=$host
MYSQL_SERVICE_DB_NAME=nacos
MYSQL_SERVICE_PORT=3306
MYSQL_SERVICE_USER=root
MYSQL_SERVICE_PASSWORD=123456
JVM_XMS=512m
JVM_XMX=512m
JVM_XMN=256m
JVM_MS=64m
JVM_MMS=128m

        在env目录下配置mysql.env。

MYSQL_ROOT_PASSWORD=123456
MYSQL_DATABASE=nacos
MYSQL_USER=root
MYSQL_PASSWORD=123456

配置docker-compose.yml

version: "3"
services:nacos1:hostname: nacos1container_name: nacos1image: nacos/nacos-server:latestvolumes:- ./data/cluster-logs/nacos1:/home/nacos/logs- ./data/init.d/custom.properties:/home/nacos/init.d/custom.propertiesports:- 8811:8848- 9811:9848- 9812:9849env_file:- ./env/nacos-hostname.envrestart: alwaysnetworks:- nacosnacos2:hostname: nacos2image: nacos/nacos-server:latestcontainer_name: nacos2volumes:- ./data/cluster-logs/nacos2:/home/nacos/logs- ./data/init.d/custom.properties:/home/nacos/init.d/custom.propertiesports:- 8822:8848- 9822:9848- 9823:9849env_file:- ./env/nacos-hostname.envrestart: alwaysnetworks:- nacosnacos3:hostname: nacos3image: nacos/nacos-server:latestcontainer_name: nacos3volumes:- ./data/cluster-logs/nacos3:/home/nacos/logs- ./data/init.d/custom.properties:/home/nacos/init.d/custom.propertiesports:- 8833:8848- 9833:9848- 9834:9849env_file:- ./env/nacos-hostname.envrestart: alwaysnetworks:- nacosnacos-nginx:networks:- nacoscontainer_name: nacos-nginximage: nginxvolumes:- ./nginx/nginx.conf:/etc/nginx/nginx.confports:- 8848:80depends_on:- nacos1- nacos2- nacos3
networks:nacos:external: false

配置nginx的nginx.conf

        在nginx/目录下配置nginx.conf文件。

# 用户组
user  nginx;# 工作进程数
worker_processes  1;# 日志路径和日志级别
error_log  /var/log/nginx/error.log warn;# 进程文件路径
pid        /var/run/nginx.pid;events {# 设置网路连接序列化accept_mutex on;# 一个进程是否同时接受多个网络连接multi_accept on;# 事件驱动模型use epoll;# 最大连接数worker_connections  1024;

}

目录的效果图

tree

        最后目录的效果图，如下：

.
├── data
│   ├── cluster-logs
│   │   ├── nacos1
│   │   ├── nacos2
│   │   ├── nacos3
│   │   └── test_nacos
│   └── init.d
│       └── custom.properties
├── docker-compose.yml
├── env
│   ├── mysql.env
│   └── nacos-hostname.env
└── nginx└── nginx.conf

启动docker-compose

docker-compose up -d

总结

        至此，通过docker-comopose搭建nacos集群成功。通过访问如下url：http://ip:8848/nacos、http://ip:8811/nacos、http://ip:8822/nacos、http://ip:8833/nacos，判断是否启动nacos成功。
