可以查看起来的portal的logs日志，可能稍微有些慢浏览器输入portal.od.com

第一件事，修改密码，任何开源软件的第一件事，就是修改默认密码

去看一下对接数据库情况

试试查询，查询key，也试试使用保存更新

key:organizations
value:[{"orgId":"ben01","orgName":"Linux学院"},{"orgId":"ben02","orgName":"云计算学院"},{"orgId":"ben03","orgName":"Python学院"},{"orgId":"ben03","orgName":"大数据学院"}]

# 11机器，查询是否更新：
~]# mysql -uroot -p
none)]> use ApolloPortalDB;
ApolloPortalDB]> select * from ServerConfig\G

使用Apollo，创建项目，提交

# 填入对应参数，并提交：
