宝塔Linux自动磁盘挂载工具 一键挂载数据盘到/www目录

我们在购买服务器时有些商家会赠送数据盘，时间久了以后我们站点数据趋于庞大，需要购买更大的磁盘来存储，此时我们需要挂载数据盘到指定的目录。今天草蜢在宝塔官方论坛看到了一个关于挂载数据盘的脚本，可以一键自动挂载数据盘到/www目录。当然如果你需要挂载到其他目录的话可以把脚本下载到本地，把“setup_path=/www”后的“/www”改成你要挂载的目录即可。

脚本说明

  1. 默认将数据盘挂载到/www目录
  2. 服务器上已存在/www目录，为了您的数据安全，挂载工具会自动跳过
  3. 服务器之前安装过Windows系统，需要手动删除NTFS分区，挂载工具会直接跳过NTFS分区
  4. 若您的磁盘已分区，且未挂载，工具会自动将分区挂载到/www
  5. 若您的磁盘是新磁盘，工具会自动分区并格式化成ext4文件系统
  6. 本工具只自动挂载一个分区，若您有多块数据盘，请手动挂载未被自动挂载的磁盘
  7. 若要挂载到其它目录，请在第一个参数传入目录名
  8. 只有一个磁盘或www目录已被挂载的情况下，自动退出脚本，不执行任何操作

输入fdisk -l 查看硬盘信息

[root@VM_0_11_centos ~]# fdisk -l

挂载命令

Centos/Fedora：

yum install wget -y && wget -O auto_disk.sh https://download.bt.cn/tools/auto_disk.sh && bash auto_disk.sh
#备用：
yum install wget -y && wget -O auto_disk.sh https://raw.githubusercontent.com/wn789/www/master/auto_disk.sh && bash auto_disk.sh

Ubuntu:

wget -O auto_disk.sh https://download.bt.cn/tools/auto_disk.sh && sudo bash auto_disk.sh
#备用：
wget -O auto_disk.sh https://raw.githubusercontent.com/wn789/www/master/auto_disk.sh && sudo bash auto_disk.sh

Debian:

wget -O auto_disk.sh https://download.bt.cn/tools/auto_disk.sh && bash auto_disk.sh
#备用：
wget -O auto_disk.sh https://raw.githubusercontent.com/wn789/www/master/auto_disk.sh && bash auto_disk.sh

草蜢用的是centos7系统，复制相应命令到ssh即可，喝口水等个2分钟，命令自动运行。小白如草蜢依然不费吹灰之力，赞一个。
