开个帖子，汇总一下读者经常提到的一些问题

问题一：Ubuntu下启动Nacos报错

问题描述

使用命令sh startup.sh -m standalone启动报错：

./startup.sh: 78: ./startup.sh: [[: not found
./startup.sh: 88: ./startup.sh: [[: not found
./startup.sh: 90: ./startup.sh: [[: not found

./startup.sh: 116: ./startup.sh: [[: not found
nacos is starting，you can check the /data/nacos/logs/start.out

解决方法

改用命令bash -f ./startup.sh -m standalone启动

问题二：Failed to create database ‘/data/soft/nacos/data/derby-data’

问题描述

使用命令sh startup.sh -m standalone启动的时候，出现如下报错：

Caused by: java.lang.RuntimeException: load schema.sql error.org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Failed to create database '/data/nacos/data/derby-data', see the next exception for details.)
