本文根据网上流行的一篇文章整理改编而成,并修正了原文的一些小错误。 由于为每一个需要使用ftp服务的用户建立系统帐户会影响系统的安全,所以我们使用数据库用户进行ftp用户验证。 系统组成: Proftpd1.2.7 proftpd-mod-quotatab-1.2.4 mysql3.23 因为ports里没有proftpd-mod-quotatab-1.2.4模块,我们下载源代码安装。 去下载proftpd-1.2.7.tar.gz。 去下载proftpd-mod-quotatab-1.2.4.tar.gz。(1.2.5 版本的mod_quotatab是用在1.2.8rc1上的) 用ftp将它们上传到/home/ylf/app目录。 然后解压缩源代码包: # cd /home/ylf/app # tar zxvf proftpd-1.2.7.tar.gz # tar zxvf proftpd-mod-quotatab-1.2.4.tar.gz 进入mod-quotatab目录 # cd mod_quotatab 把mod_quotatab中的文件拷贝到proftpd 中的modules 目录中 # cp * ../proftpd-1.2.7/modules 在开始运行configure之前,我们要先改动一个文件 进入 proftpd-1.2.7/contrib 目录 # cd /home/ylf/app/proftpd-1.2.7/contrib 修改 mod_sql_mysql.c # vi mod_sql_mysql.c 找到#include 把他改为你的实际路径,这里是: #include 然后编译安装: # cd /home/ylf/app/proftpd-1.2.7 #./configure --prefix=/usr/local/proftpd --with-modules=mod_sql:mod_sql_mysql:mod_quotatab:mod_quotatab_sql --with-includes=/usr/local/include/mysql --with-libraries=/usr/local/lib/mysql # make # make install 进入到proftpd配置文件所在目录 备份原配置文件 # mv proftpd.conf proftpd.conf.bak 然后编辑新的配置文件proftpd.conf # vi proftpd.conf 我的proftpd.conf内容如下: # This is a basic ProFTPD configuration file (rename it to # 'proftpd.conf' for actual use.
