Linux(以CentOS为例)下编译安装pureftpd(虚拟用户)

Linux下ftp服务器使用者貌似以pureftpd居多，于是我就尝试在centos下编译安装pureftpd，几番折腾后终于成功了...

直接上代码吧

wget http://download.pureftpd.org/pub/pure-ftpd/releases/pure-ftpd-1.0.42.tar.gz --no-check-certificate
tar zxvf pure-ftpd-1.0.42.tar.gz
cd pure-ftpd-1.0.42
./configure --prefix=/usr/local/pureftpd CFLAGS=-O2 --with-puredb --with-quotas --with-cookie --with-virtualhosts --with-diraliases --with-sysquotas --with-ratios --with-altlog --with-paranoidmsg --with-shadow --with-welcomemsg --with-throttling --with-uploadscript --with-language=english --with-rfc2640 --with-ftpwho
make && make install
mkdir /usr/local/pureftpd/etc

cp configuration-file/pure-ftpd.conf /usr/local/pureftpd/etc/

cp configuration-file/pure-config.pl /usr/local/pureftpd/sbin/

chmod 755 /usr/local/pureftpd/sbin/pure-config.pl

修改配置文件/usr/local/pureftpd/etc/pure-ftpd.conf

#取消注释并修改为如下 (看清楚，需要修改配置文件中puredb的路径)

PureDB                        /usr/local/pureftpd/etc/pureftpd.pdb

启动pureftpd

/usr/local/pureftpd/sbin/pure-config.pl /usr/local/pureftpd/etc/pure-ftpd.conf --daemonize

关闭pureftpd

kill `cat /var/run/pure-ftpd.pid`

添加ftp用户组和用户

groupadd ftpgroup
useradd ftpuser -g ftpgroup -d /home/ftp -s /sbin/nologin

/usr/local/pureftpd/bin/pure-pw useradd username -u ftp -d /home/wwwroot/default

写入数据库

/usr/local/pureftpd/bin/pure-pw mkdb

pure-pw useradd <login> [-f <passwd file>] -u <uid> [-g <gid>]
             -D/-d <home directory> [-c <gecos>]
             [-t <download bandwidth>] [-T <upload bandwidth>]
             [-n <max number of files>] [-N <max Mbytes>]
             [-q <upload ratio>] [-Q <download ratio>]
             [-r <allow client host>[/<mask>][,<allow client host>[/<mask>]]...]
             [-R <deny client host>[/<mask>][,<deny client host>[/<mask>]]...]
             [-i <allow local host>[/<mask>][,<allow client host>[/<mask>]]...]
             [-I <deny local host>[/<mask>][,<deny local host>[/<mask>]]...]
             [-y <max number of concurrent sessions>]
             [-z <hhmm>-<hhmm>] [-m]

pureftpd每次添加用户后需要写入数据库，重启pureftpd后生效

如果配置都正确，出现530错误，请参考

把pure-ftpd.conf 中的 MinUID 值改为2（原来为100，改小一些，不是非2不可，MinUID为FTP用户UID的最小值，本次添加的FTP用户UID小于100，不符合此条件，故登录530。

需要给FTP目录增加读写权限和文件夹用户修改为ftp用户

chmod -R 755 dir_path
chown -R ftp:ftp dir_path
