创建数据库、用户名、导入表结构

$  mysql -h 192.168.23.21 -u root  -P 30006  -p'password'
mysql> create database nacos_config character set utf8;
mysql> create user 'nacos'@'%' identified by 'nacos';
mysql> grant all privileges ON nacos_config.* TO 'nacos'@'%';
mysql>use nacos_config;	$ wget https://raw.githubusercontent.com/alibaba/nacos/develop/distribution/conf/mysql-schema.sql
$  mysql -h 192.168.23.21 -u root  -P 30006  -p'password' -D nacos_config < mysql-schema.sql
$  mysql -h 192.168.23.21 -u root  -P 30006  -p'password' -D nacos_config

NOTES:
1. Get the application URL by running these commands:export NODE_PORT=$(kubectl get --namespace default -o jsonpath="{.spec.ports[0].nodePort}" services  nacos-cs)export NODE_IP=$(kubectl get nodes --namespace default -o jsonpath="{.items[0].status.addresses[0].address}")echo http://$NODE_IP:$NODE_PORT/nacos
2. MODE:standalone: you need to modify replicaCount in the values.yaml, .Values.replicaCount=1cluster: kubectl scale sts default-nacos --replicas=3
