之前我們玩的是單機，在這個基礎上，我們玩個集群
很簡單 ，下面我們開始哈
首先我們有了MySQL 沒有的看我其他的博客，或者docker 新來一個
docker pull nacos/nacos-server #拉取nacos鏡像 #創建掛載文件路徑 mkdir -p /usr/local/nacos/logs1 /usr/local/nacos/logs2 /usr/local/nacos/logs3 mkdir -p /usr/etc/nacos/conf1 /usr/etc/nacos/conf2 /usr/etc/nacos/conf3
docker cp 18fa206c4883:/home/nacos/conf /usr/etc/nacos/conf #復制nacos配置目錄到宿主機（或從其他地方復制需要application.properties、cluster.conf） #創建自定義網絡 docker network create --driver bridge --subnet 172.16.0.0/16 self_network #啟動mysql容器 docker create -p 3306:3306 --network self_network --network-alias mysql --name mysql8.0 -e MYSQL_ROOT_PASSWORD=123456 -v /usr/etc/mysql8.0/mysql/conf:/etc/mysql -v /usr/etc/mysql8.0/mysql/logs:/var/log/mysql -v /usr/etc/mysql8.0/mysql/data:/var/lib/mysql -v /usr/etc/mysql8.0/mysql/mysql-files:/var/lib/mysql-files mysql
#創建三個nacos容器

docker network ls
查看docker網卡
docker network rm 網卡id
刪除docker網卡
docker network inspect 網卡id
查看docker網卡的相關詳細信息
docker logs -f -n 9999 65c48cdba624
