配置FTP服務

pure-ftpd 官網是 http://www.pureftpd.org/project/pure-ftpd

1. 下載軟件

[root@localhost ~]# cd /usr/local/src/
[root@localhost src]# wget http://download.pureftpd.org/pub/pure-ftpd/releases/pure-ftpd-1.0.42.tar.bz2

2. 安裝pure-ftpd

[root@localhost src]# tar jxf pure-ftpd-1.0.42.tar.bz2
[root@localhost src]# cd pure-ftpd-1.0.42
[root@localhost pure-ftpd-1.0.42]# ./configure \
--prefix=/usr/local/pureftpd \
--without-inetd \
--with-altlog \
--with-puredb \
--with-throttling \
--with-peruserlimits  \
--with-tls
[root@localhost pure-ftpd-1.0.42]# make && make install

配置pure-ftpd

[root@localhost pure-ftpd-1.0.42]# cd configuration-file
[root@localhost pure-ftpd-1.0.42]# mkdir -p /usr/local/pureftpd/etc/
[root@localhost configuration-file]# cp pure-ftpd.conf    /usr/local/pureftpd/etc/pure-ftpd.conf
[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

在啓動pure-ftpd以前須要先修改配置文件，配置文件爲/usr/local/pureftpd/etc/pure-ftpd.conf

ChrootEveryone              yes

MaxClientsNumber            50

CustomerProof              yes

2. 啓動pure-ftpd

[root@localhost ~]# /usr/local/pureftpd/sbin/pure-config.pl /usr/local/pureftpd/etc/pure-ftpd.conf

若是是啓動成功，會顯示一行長長的以Running開頭的信息，不然那就是錯誤信息，若是你解決不了，請自行百度

3. 創建帳號

[root@localhost ~]# mkdir /data/www/
[root@localhost ~]# useradd www
[root@localhost ~]# chown -R www:www /data/www/
[root@localhost ~]# /usr/local/pureftpd/bin/pure-pw useradd qiang -uwww -d /data/www/
Password:
Enter it again:

其中，-u將虛擬用戶qiang與系統用戶www關聯在一塊兒，也就是說使用qiang帳號登錄ftp後，會以www的身份來讀取文件或下載文件。-d 後邊的目錄爲qiang帳戶的家目錄，這樣能夠使qiang只能訪問其家目錄/data/www/. 到這裏還未完成，還有最關鍵的一步，就是建立用戶信息數據庫文件:

[root@localhost ~]#  /usr/local/pureftpd/bin/pure-pw mkdb

pure-pw還能夠列出當前的ftp帳號，固然也能夠刪除某個帳號, 咱們再建立一個帳號:

[root@localhost ~]#  /usr/local/pureftpd/bin/pure-pw  useradd wang -uwww -d /tmp
[root@localhost ~]#  /usr/local/pureftpd/bin/pure-pw mkdb

列出當前帳號:

[root@localhost ~]# /usr/local/pureftpd/bin/pure-pw list

刪除帳號的命令爲:

[root@localhost ~]#  /usr/local/pureftpd/bin/pure-pw  userdel wang

測試pure-ftpd

[root@localhost ~]# yum install -y lftp

測試:

[root@localhost ~]# touch /data/www/123.txt
[root@localhost ~]# lftp qiang@127.0.0.1
口令:
lftp qiang@127.0.0.1:~> ls
drwxr-xr-x    2 514        www              4096 Jun 12 11:14 .
drwxr-xr-x    2 514        www              4096 Jun 12 11:14 ..
-rw-r--r--    1 514        www                 0 Jun 12 11:14 123.txt

登錄後，使用 ls 命令能夠列出當前目錄都有什麼文件。
