linux下安装FTP

1、什么是FTP

FTP（file transfer protocol）文件传输协议，可以使主机之间共享文件。

2、使用pure-ftp搭建FTP服务

下载pure-ftp软件包

[root@localhost src]# wget http://download.pureftpd.org/pub/pure-ftpd/releases/pure-ftpd-1.0.32.tar.bz2

解压安装包

[root@localhost src]# tar jxvf pure-ftpd-1.0.32.tar.bz2

配置pure-ftp

[root@localhost src]# cd pure-ftpd-1.0.32
[root@localhost pure-ftpd-1.0.32]# ./configure --prefix=/usr/local/pureftpd --without-inetd --with-altlog --with-puredb --with-throttling --with-peruserlimits --with-tls

编译安装

[root@localhost pure-ftpd-1.0.32]# make && make install

查看/usr/local/pureftpd/目录下生成的文件

[root@localhost pure-ftpd-1.0.32]# ls /usr/local/pureftpd/
bin  sbin  share

复制配置文件

[root@localhost pure-ftpd-1.0.32]# mkdir -p /usr/local/pureftpd/etc/
[root@localhost pure-ftpd-1.0.32]# cd configuration-file/
[root@localhost configuration-file]# ls
Makefile     Makefile.in     pure-config.pl.in  pure-config.py.in  pure-ftpd.conf.in
Makefile.am  pure-config.pl  pure-config.py     pure-ftpd.conf
[root@localhost configuration-file]# cp pure-ftpd.conf /usr/local/pureftpd/etc/
[root@localhost configuration-file]# cp pure-config.pl /usr/local/pureftpd/sbin/pure-config.pl
[root@localhost configuration-file]# chmod 755 /usr/local/pureftpd/sbin/pure-config.pl

编写配置文件pure-ftpd.conf

[root@localhost configuration-file]# vim /usr/local/pureftpd/etc/pure-ftpd.conf
ChrootEveryone yes 
 //用户只能在他的家目录
BrokenClientsCompatibility no
MaxClientsNumber 50
//最大并发的用户
Daemonize yes
//在后台运行进程
MaxClientsPerIP 8
VerboseLog no 
//If you want to log all client commands, set this to "yes".
DisplayDotFiles yes
AnonymousOnly no
//Don‘t allow authenticated users - have a public anonymous FTP only.
NoAnonymous no
 //Disallow anonymous connections. Only allow authenticated users.
SyslogFacility ftp
DontResolve yes
 // Don‘t resolve host names in log files. Logs are less verbose,
// butit uses less bandwidth. Set this to "yes" on very busy servers or
 //if you don‘t have a working DNS.
MaxIdleTime 15
 //Maximum idle time in minutes (default = 15 minutes)
PureDB /usr/local/pureftpd/etc/pureftpd.pdb
 //用户数据库
LimitRecursion 3136 8
//‘ls‘ recursion limits. The first argument is the maximum number offiles to be displayed.
//The second one is the max subdirectories depth
AnonymousCanCreateDirs no 
 //Are anonymous users allowed to create new directories ?
MaxLoad 4
 //If the system is more loaded than the following //value,anonymous users aren‘t allowed to download.
AntiWarez yes 
 //Disallow downloading of files owned by "ftp", ie.files that were uploaded but not validated by a local admin.
Umask 133:022
 //File creation mask. <umask for files>:<umask for dirs> .
MinUID 100
 //Minimum UID for an authenticated user to log in.
AllowUserFXP no
 //Allow FXP transfers for authenticated users.
AllowAnonymousFXP no
//Allow anonymous FXP for anonymous and non-anonymous users.
ProhibitDotFilesWrite no
// Users can‘t delete/write files beginning with a dot (‘.‘)even if they own them.
ProhibitDotFilesRead no
// Prohibit *reading* of files beginning with a dot (.history, .ssh...)
AutoRename no
//Never overwrite files. When a file whoose name already exist is uploaded,
//it get automatically renamed to file.1, file.2, file.3, ...
AnonymousCantUpload no
// Disallow anonymous users to upload new files (no = upload is allowed)
PIDFile /usr/local/pureftpd/var/run/pure-ftpd.pid
//If your pure-ftpd has been compiled with standalone support,
 //you can change the location of the pid file. The default is /var/run/pure-ftpd.pid
MaxDiskUsage 99
CustomerProof yes
 //If you‘re sure all your users have some basic Unix knowledge,
//this feature is useless. If you‘re a hosting service, enable it.

创建FTP服务目录

[root@localhost configuration-file]# mkdir /data/ftp
[root@localhost configuration-file]# useradd www
[root@localhost configuration-file]# passwd www
Changing password for user www.
New password:
BAD PASSWORD: it is too simplistic/systematic
BAD PASSWORD: is too simple
Retype new password:
passwd: all authentication tokens updated successfully.
[root@localhost configuration-file]# chown -R www:www /data/ftp  //更改属主属组

用系统账号需创建虚拟FTP账号

[root@localhost configuration-file]# /usr/local/pureftpd/bin/pure-pw useradd ftp1 -uwww -d/data/ftp
Password:
Enter it again:
//创建虚拟账号
[root@localhost configuration-file]# /usr/local/pureftpd/bin/pure-pw mkdb
//创建密码文件，二进制文件
[root@localhost configuration-file]# /usr/local/pureftpd/bin/pure-pw  list
ftp1                /data/ftp/./
//列出虚拟账号
[root@localhost configuration-file]# /usr/local/pureftpd/bin/pure-pw useradd ftp2 -uwww -d /data/ftp
Password:
Enter it again:
][root@localhost configuration-file]# /usr/local/pureftpd/bin/pure-pw passwd ftp2
Password:
Enter it again:
//修改虚拟账号密码
[root@localhost configuration-file]# /usr/local/pureftpd/bin/pure-pw userdel ftp2
//删除虚拟账号
[root@localhost configuration-file]# /usr/local/pureftpd/bin/pure-pw list
ftp1                /data/ftp/./

启动pure-ftp

[root@localhost configuration-file]# /usr/local/pureftpd/sbin/pure-config.pl /usr/local/pureftpd/etc/pure-ftpd.conf
Running: /usr/local/pureftpd/sbin/pure-ftpd -A -c50 -B -C8 -D -fftp -H -I15 -lpuredb:/usr/local/pureftpd/etc/pureftpd.pdb -L3136:8 -m4 -s -U133:022 -u100 -g/usr/local/pureftpd/var/run/pure-ftpd.pid -k99 -Z

[root@localhost configuration-file]# netstat -anpt |grep pure

访问pure-ftp

[root@client ~]# lftp [email protected]  //客户机

lftp [email protected]:~> ls
