Alibaba Nacos 学习（五）：K8S Nacos搭建,使用nfs

准备环境

Centos7  192.168.50.21 k8s-master 2G
Centos7  192.168.50.22 k8s-node01 2G
Centos7  192.168.50.23 k8s-node02 2G

K8S集群搭建参考  https://www.cnblogs.com/woxpp/p/11875547.html

master安装好Git ,yum install git

master,node01,node02  安装 nfs-utils

yum install nfs-utils

master,node01,node02添加nfs exports配置，为了解决后续的nfs报错异常

https://img.qb5200.com/download-x/data/mysql-slave *(insecure,fsid=0,rw,async,no_root_squash)
https://img.qb5200.com/download-x/data/mysql-master *(insecure,fsid=0,rw,async,no_root_squash)
https://img.qb5200.com/download-x/data/nfs-share *(rw,fsid=0,sync,no_root_squash)

mysql-slave 数据库从库 

mysql-master 数据库主库

nfs-share nocas文件挂在目录

后面的yml中会提到
master,node01,node02创建目录

mkdir https://img.qb5200.com/download-x/data/mysql-slave
mkdir https://img.qb5200.com/download-x/data/mysql-master
mkdir https://img.qb5200.com/download-x/data/nfs-share 

 master 克隆代码

   git clone https://github.com/nacos-group/nacos-k8s.git

克隆完成进入以下目录

 cd /opt/nacos-k8shttps://img.qb5200.com/download-x/deploy/

1.nfs安装

kubectl create -f nfs/rbac.yaml 

kubectl create -f nfs/class.yaml 

修改nfshttps://img.qb5200.com/download-x/deployment.yaml IP配置

kubectl create -f nfshttps://img.qb5200.com/download-x/deployment.yaml

查看安装状态

kubectl get pod -l app=nfs-client-provisioner

2.mysql部署

cd /opt/nacos-k8shttps://img.qb5200.com/download-x/deploy/mysql/

修改数据配置文件ip

vi mysql-master-nfs.yaml

 部署主库

kubectl create -f mysql-master-nfs.yaml 

修改存库ip

vi mysql-slave-nfs.yaml

kubectl create -f mysql-slave-nfs.yaml 

主从部署非常慢 耐心等待，如果报nfs相关的错，重启nfs即可

service nfs restart

3. 部署nacos

cd /opt/nacos-k8shttps://img.qb5200.com/download-x/deploy/nacos/

kubectl create -f nacos-pvc-nfs.yaml 

 查看访问端口

kubectl get svc|grep nacos

 查看K8S集群状态

 Failed to pull image "nacos/nacos-server:latest": rpc error: code = Unknown desc = context canceled

进去对应节点机器 ，拉取镜像后，重新应用即可

kubectl apply -f

 4. 部署问题

部署过程中大部分都是NFS问题

可以参考https://blog.csdn.net/wuxinyicomeon/articlehttps://img.qb5200.com/download-x/details/6292132

mount.nfs: No route to host

修改deployment.yaml中server的IP地址为某个node节点的内网IP地址，图1已标注
