基本说明
- 环境：ubuntu系统
本地测试http链接是否生效
测试链接http://175.178.211.247:3000/，有可能3000端口防火墙没开放，可以测试curl -I http://localhost:3000/这样可以规避防火墙直接测试接口
root@VM-8-14-ubuntu:~# curl -I http://175.178.211.247:3000/

文件链接下载
执行linux命令：wget <url>
比如下载dokuwiki源码：
vg-db@vgdb-Z10PA-D8-Series:~$ wget https://download.dokuwiki.org/out/dokuwiki-a6b3119b5d16cfdee29a855275c5759f.tgz

压缩文件解压
在Ubuntu系统中解压.tgz文件，你可以使用tar命令，该命令既能处理打包操作也能处理gzip压缩。解压.tgz文件的具体命令如下：
tar xvf file.tgz
这里的命令参数意义如下：
x：代表解包（extract）。
v：表示详细模式（verbose），在处理文件时会显示详细的信息。
f：后面跟文件名，指定要处理的归档文件。
如果需要将文件解压到特定目录，可以使用 -C 参数后跟目标目录，例如：
tar xvf file.tgz -C /path/to/extract/to
这会将file.tgz中的内容解压到/path/to/extract/to目录下。
请确保将file.tgz替换为你实际需要解压的文件名。
查看磁盘和分区信息
不显示挂载点的磁盘使用情况
lsblk
查询结果
sda、sdb、sdc分别是3个硬盘，树形下面列出来的就是该硬盘对应的分区，对应分的MOUNTPOINT列下没有路径的话表示没有挂载，系统安装在分区sda5所以挂载点为根目录\，主机上还安装了另外两个硬盘sdb和sdc，这两个硬盘的MOUNTPOINT列没有路径，表示没有挂载到文件系统，所以这两个分区不可用

ubuntu系统默认根目录为系统安装分区，其他硬盘或分区分别在目录/media下，系统默认是没有把这些分区挂载到文件系统的
