1、部署mysql

1.1 Mysql密码加密

#your_password改为实际的密码，并复制生成的base值粘贴到1.2小节的data.pass
echo -n 'your_password' | base64

#创建nfs挂载数据目录
mkdir -p /data/nfs-data/mysql-data

1.3 验证Mysql

kubectl -n nacos get pod

kubectl -n nacos exec -it nacos-mysql-0 -- mysql -uroot -p'your_password'

1.4 创建nacos数据库并初始化数据

create database nacos;
user nacos;
