ftp服务挂载本地目录：Linux工具CurlFTPfs安装与使用

CurlFTPfs 是一个基于 FUSE（Filesystem in Userspace）的文件系统，它允许将 FTP 服务器挂载为本地文件系统。下载地址：https://sourceforge.net/projects/curlftpfs/files/latest/download

软件安装过程如下，底层是centos7+Intel x86环境

--下载后解压
[root@localhost software]# tar -xzvf curlftpfs-0.9.2.tar.gz
curlftpfs-0.9.2  curlftpfs-0.9.2.tar.gz
[root@localhost software]# cd curlftpfs-0.9.2/
--编译（提前安装以下组件，不然可能缺失报错）
[root@localhost curlftpfs-0.9.2]# yum install fuse* 
[root@localhost curlftpfs-0.9.2]# yum install libcurl
[root@localhost curlftpfs-0.9.2]# yum install libcurl-devel

首先确保ftp服务是正常的

[root@localhost ~]# yum install ftp
[root@localhost ~]# ftp
ftp> open 192.168.1.200
Connected to 192.168.1.200 (192.168.1.200).

ftp> ls

[root@localhost ~]# 

创建本地目录用来挂载ftp

[root@localhost soft]# mkdir -p /soft/curlftpfs_local     

使用 CurlFTPfs 将 FTP 服务器挂载为本地目录

---标准命令：curlftpfs -o user=$FTP_USER:$FTP_PASS $FTP_SERVER /mnt/ftp
[root@localhost soft]# curlftpfs -o user=lzb:123456789 ftp://192.168.1.200 /soft/curlftpfs_local/
[root@localhost soft]# df -h

配置为开机自启

[root@localhost soft]# cat /etc/fstab

测试目前虽然可以挂载，但是直接通过ftp挂载目录创建文件并编辑，第一遍可以编辑，但是保存会提示Fsync failed，但是实际是存进去的，第二次之后就无法修改生效；挂载目录中文件cp也会报错Input/output error，但是cp到其他非ftp挂载目录是没有问题的。目前貌似不是操作问题是curlftpfs版本及依赖的fuse\libcurl组件版本直接的关系，某些版本组合下没有这些问题，有用到的伙伴欢迎分享。
