### 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: 96: ./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：
