【6.4】服务器安装 Docker Swarm中搭建 Nacos 集群

搭建单节点nacos 请看这里

以下是nacos 集群搭建方法一

# 节点一
docker run -d \
 -e PREFER_HOST_MODE=hostname \
 -e MODE=cluster \
 -e NACOS_SERVER_PORT=8948 \
 -e NACOS_SERVER_IP=192.168.0.105 \
 -e NACOS_SERVERS="192.168.0.105:8948 192.168.0.103:8948 192.168.0.103:8949" \
 -e SPRING_DATASOURCE_PLATFORM=mysql \
 -e MYSQL_SERVICE_HOST=192.168.0.105 \
 -e MYSQL_SERVICE_PORT=4002 \
 -e MYSQL_SERVICE_USER=root \
 -e MYSQL_SERVICE_PASSWORD=admin \
 -e MYSQL_SERVICE_DB_NAME=nacos \
 -p 8948:8848 --net=swarm_test \
 --name nacos1 \
 nacos/nacos-server:latest

# 节点二
docker run -d \
  -e PREFER_HOST_MODE=hostname \
 -e MODE=cluster \
 -e NACOS_SERVER_PORT=8948 \
 -e NACOS_SERVERS="192.168.0.105:8948 192.168.0.103:8948 192.168.0.103:8949" \
 -e SPRING_DATASOURCE_PLATFORM=mysql \
 -e MYSQL_SERVICE_HOST=192.168.0.105 \
 -e MYSQL_SERVICE_PORT=4002 \
 -e MYSQL_SERVICE_USER=root \
 -e MYSQL_SERVICE_PASSWORD=admin \
 -e MYSQL_SERVICE_DB_NAME=nacos \
 -e NACOS_SERVER_IP=192.168.0.103 \
 -p 8948:8848 --net=swarm_test \
 --name nacos2 \
 nacos/nacos-server:latest

# 节点三
docker run -d \
  -e PREFER_HOST_MODE=hostname \
 -e MODE=cluster \
 -e NACOS_SERVER_PORT=8949 \
 -e NACOS_SERVERS="192.168.0.105:8948 192.168.0.103:8948 192.168.0.103:8949" \
 -e SPRING_DATASOURCE_PLATFORM=mysql \
 -e MYSQL_SERVICE_HOST=192.168.0.105 \
 -e MYSQL_SERVICE_PORT=4002 \
 -e MYSQL_SERVICE_USER=root \
 -e MYSQL_SERVICE_PASSWORD=admin \
 -e MYSQL_SERVICE_DB_NAME=nacos \
 -e NACOS_SERVER_IP=192.168.0.103 \
 -p 8949:8848 --net=swarm_test \
 --name nacos3 \
 nacos/nacos-server:latest

方法二
用户密码参考docker-compose-swarm-nacos.yml
nacos-mysql.sql

#docker-compose-swarm-nacos.yml
#node.id为docker swarm 节点id
