二进制部署k8s集群v1.23.9版本-20-安装nacos-2.0.3

20.1、准备镜像

192.168.1.200操作
docker pull nacos/nacos-server
docker images |grep nacos
docker tag bdf60dc2ada3 harbor.qgutech.com/middleware/nacos:v2.0.3
docker push bdf60dc2ada3 harbor.qgutech.com/middleware/nacos:v2.0.3

20.2、准备资源配置清单

192.168.1.200操作

mkdir -p /data/k8s-yaml/nacos/
cd /data/k8s-yaml/nacos/

20.3、创建挂载卷

192.168.1.200操作
mkdir -p /data/nfs-volume/nacos/data
mkdir -p /data/nfs-volume/nacos/logs
mkdir -p /data/nfs-volume/nacos/conf

20.4、内网域名解析

192.168.1.197操作
vim /var/named/qgutech.com.zone
增加一条解析记录，注意序列号前滚
nacos-test A 192.168.1.196

重启named服务
systemctl restart named
dig -t A nacos-test.qgutech.com @192.168.1.197 +short

20.5、应用资源配置清单

192.168.1.201操作
kubectl apply -f http://k8s-yaml.qgutech.com/nacos/dp.yaml
kubectl apply -f http://k8s-yaml.qgutech.com/nacos/svc.yaml
kubectl apply -f http://k8s-yaml.qgutech.com/nacos/ingress.yaml

界面访问
http://nacos-test.qgutech.com/nacos
用户名：nacos
密码：nacos
如下图所示：

至此，nacos安装完成，谢谢观看。
