第一步 配置网络 创建docker虚拟网络

1. 创建一个名为clickhouse的桥接(bridge)虚拟网络，网关172.26.0.1，网段为172.25.0.0

（为了让后面nacos 和 mysql 在同一个网络内 如果是多台服务器 可以不用这样部署 ）

docker network create -d bridge --subnet=172.26.0.0/16 --gateway=172.26.0.1 clickhouse

编辑docker-compose.yml文件

version: "3.7"
services:
  mysql-nacos:
    container_name: mysql-nacos
    networks:
      clickhouse:
        ipv4_address: 172.26.0.110

先运行数据库的部署然后在登录mysql

mysql -uroot -proot

创建用户

CREATE USER 'nacos'@'%' identified by 'nacos';

赋予权限

grant all privileges on nacos_devtest.* to 'nacos'@'%' with GRANT OPTION;

刷新权限

flush privileges;

导入nacos数据

order_nacos_config.sql

最后在部署nacos 就行了

配置完登录nacos 就可以看到我们的集群节点了

（遇到的坑：naocs开启权限认证后 项目连不上nacos 这个网上说是nacos的bug 有遇到这个问题解决得小伙伴 可以分享一下）
