Nacos - 通过Docker 部署nacos 的集群版本 3实例

---

1、获取镜像

docker pull nacos/nacos-server

2、运行镜像，外部数据库模式

按自己的实际配置填充 ******部分的配置即可

配置一

docker run \
  --name nacos-1 \
  --hostname=nacos-1 \
  --restart=always \
  -d \
  -e MYSQL_MASTER_SERVICE_HOST=****** \
  -e MYSQL_MASTER_SERVICE_PORT=****** \
  -e MYSQL_MASTER_SERVICE_DB_NAME=****** \
  -e MYSQL_MASTER_SERVICE_USER=****** \
  -e MYSQL_MASTER_SERVICE_PASSWORD=****** \
  -e SPRING_DATASOURCE_PLATFORM=mysql \
  -e MYSQL_DATABASE_NUM=1 \
  -e NACOS_USER=nacos.test \
  -e NACOS_PASSWORD=****** \
  -e NACOS_SERVERS=172.17.0.2:8848,172.17.0.7:8848,172.17.0.8:8848 \
  -e JVM_XMS=512m \
  -e JVM_XMX=512m \
  -e JVM_XMN=256m \
  -e JVM_MS=32m \
  -e JVM_MMS=80m \
  -p 65210:8848 \
  nacos/nacos-server

配置二

docker run \
  --name nacos-2 \
  --hostname=nacos-2 \
  --restart=always \
  -d \
  -e MYSQL_MASTER_SERVICE_HOST=****** \
  -e MYSQL_MASTER_SERVICE_PORT=****** \
  -e MYSQL_MASTER_SERVICE_DB_NAME=****** \
  -e MYSQL_MASTER_SERVICE_USER=****** \
  -e MYSQL_MASTER_SERVICE_PASSWORD=****** \
  -e SPRING_DATASOURCE_PLATFORM=mysql \
  -e MYSQL_DATABASE_NUM=1 \
  -e NACOS_USER=nacos.test \
  -e NACOS_PASSWORD=****** \
  -e NACOS_SERVERS=172.17.0.2:8848,172.17.0.7:8848,172.17.0.8:8848 \
  -e JVM_XMS=512m \
  -e JVM_XMX=512m \
  -e JVM_XMN=256m \
  -e JVM_MS=32m \
  -e JVM_MMS=80m \
  -p 65211:8848 \
  nacos/nacos-server
  

配置三

docker run \
  --name nacos-3 \
  --hostname=nacos-3 \
  --restart=always \
  -d \
  -e MYSQL_MASTER_SERVICE_HOST=****** \
  -e MYSQL_MASTER_SERVICE_PORT=****** \
  -e MYSQL_MASTER_SERVICE_DB_NAME=****** \
  -e MYSQL_MASTER_SERVICE_USER=****** \
  -e MYSQL_MASTER_SERVICE_PASSWORD=****** \
  -e SPRING_DATASOURCE_PLATFORM=mysql \
  -e MYSQL_DATABASE_NUM=1 \
  -e NACOS_USER=nacos.test \
  -e NACOS_PASSWORD=****** \
  -e NACOS_SERVERS=172.17.0.2:8848,172.17.0.7:8848,172.17.0.8:8848 \
  -e JVM_XMS=512m \
  -e JVM_XMX=512m \
  -e JVM_XMN=256m \
  -e JVM_MS=32m \
  -e JVM_MMS=80m \
  -p 65212:8848 \
  nacos/nacos-server

3、通过nginx 做负载均衡

upstream nacos {   
  	 server localhost:65210 weight=1 max_fails=2 fail_timeout=10s;   
	 server localhost:65211 weight=1 max_fails=2 fail_timeout=10s;
	 server localhost:65212 weight=1 max_fails=2 fail_timeout=10s;
}



location  ~* \.(php|jsp|cgi|asp|aspx)$
{
    proxy_pass http://nacos;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header REMOTE-HOST $remote_addr;
}

location /
{
    proxy_pass http://nacos;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header REMOTE-HOST $remote_addr;

    add_header X-Cache $upstream_cache_status;
    
    #Set Nginx Cache
    
    	add_header Cache-Control no-cache;
}
