k8s集群中集群方式安装nacos

1、前提条件

• 一个k8s集群，其中有三个master 节点，这三个节点的标签名称为etcd
  三个master节点的ip 分别为：192.165.187.170 、192.165.187.171、192.165.187.172
• 一个mysql 数据库， 数据库的ip 为：192.165.187.180 用户名：root 密码：123456

2、准备nacos 数据库

在mysql 数据库中创建一个nacos名称的数据库，然后执行下面的建表语句

3、 nacos的安装

1、下载镜像

docker pull nacos/nacos-server:v2.2.3

2、安装的yaml文件 nacos.yaml 文件如下：

---

安装的名称空间在 kube-system
k8s.kuboard.cn/role: etcd 这个需要注意，这个标签里面一定要包含你要安装的三个节点

• 安装方式一、kubectl安装：
  把需要的yaml 修改好后，把nacos.yaml 放到在master1上，进入所在的目录中执行：

kubectl apply -f nacos.yaml

即可安装成功

• 方式二、 在kuboard中安装
  1、进入kuboard 的kube-system名称空间，点击导入工作负载。
  

根据提示一步一步操作即可。
