一、环境说明
腾讯 云主机或者Ucloud云云主机,系统为Centos6 X86_64位,云主机本地不需要开启防火墙,只需要控制台安全组做防火墙策略就行,如下截图放开pureftpd的登录端口
二、pureftpd源码编译安装
yum -y install make gcc gcc-c++ gcc-g77 openssl openssl-devel
wget https://download.pureftpd.org/pub/pure-ftpd/releases/pure-ftpd-1.0.49.tar.gz
tar xf pure-ftpd-1.0.49.tar.gz
cd pure-ftpd-1.0.49
./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 --with-tls
make &&make install
chmod +x /etc/init.d/pureftpd
chkconfig pureftpd on
touch /usr/local/pureftpd/etc/pureftpd.passwd
touch /usr/local/pureftpd/etc/pureftpd.pdb
echo "export PATH=$PATH:/usr/local/pureftpd/sbin:/usr/local/pureftpd/bin" > /etc/profile.d/pureftpd.sh
source /etc/profile
三、pureftpd配置文件介绍
下面是生成环境pure-ftpd.conf的配置文件参数,pureftpd的配置文件中参数后面是不支持#号注释的,所以生产上要去掉参数后面的#注释,否则启动pureftpd会报错
[root@10-9-156-50 ~]# cat /usr/local/pureftpd/etc/pure-ftpd.conf
chrootEveryone yes
BrokenClientsCompatibility no
MaxClientsNumber 50
Daemonize yes
MaxClientsPerIP 10
VerboseLog no
DisplayDotFiles yes
AnonymousOnly no
NoAnonymous yes
SyslogFacility ftp
DontResolve yes
MaxIdleTime 15
PureDB /usr/local/pureftpd/etc/pureftpd.pdb
LimitRecursion 10000 8
AnonymousCanCreateDirs no
MaxLoad 4
PassivePortRange 2037 2045 ###端口范围默认是20000到30000之间,安全起见可以给定的小一点
ForcePassiveIP 117.50.12.93 ##云主机默认的网卡为内网卡,所以此处必须绑定VPS的外网ip
AntiWarez yes
Bind ,2038
Umask 133:022
MinUID 100
AllowUserFXP no
AllowAnonymousFXP no
ProhibitDotFilesWrite no
ProhibitDotFilesRead no
AutoRename no
AnonymousCantUpload yes
PIDFile /var/run/pure-ftpd.pid
MaxDiskUsage 99
UserBandwidth 80 ##默认允许上传才8KB
问题的原因:服务器存在内网IP,而pureftp没有设置被动模式返回的IP地址,默认返回了内网的IP导致客户端无法链接。

四、pure-ftpd日常操作应用
说明:为了安全起见purevtpd一般是禁止匿名用户登录ftp的,pureftpd服务主要是通过服务器本地的系统虚拟用户来创建ftp的登录账户的。然而在选用服务器系统本地的虚拟用户是有要求的,要求虚拟用户的uid不能小于100,要是uid小于100的话,通过此虚拟用户创建的ftp登录账户是登录不了ftp的,会提示密码不正确(这个是经过本人多次验证测试过的)
对于web服务的站点工程目录一般给的权限是www或者apache的系统虚拟用户的权限
4.1采用系统默认的虚拟apache的用户
如果采用的是系统默认存在的apache用户的话,此用户默认的uid和gid都是48,小于100,必须直接修改成大于等于100的数值
默认值如下:
[root@localhost ~]# grep apache /etc/passwd
apache:x:48:48::/home/apache:/sbin/nologin
[root@localhost ~]# grep apache /etc/group
apache:x:48:
[root@localhost www]# id apache
uid=48(apache) gid=48(apache) groups=48(apache)
直接编辑配置文件修改后的值如下:
[root@localhost ~]# grep apache /etc/passwd
apache:x:100:100::/home/apache:/sbin/nologin
[root@localhost ~]# grep apache /etc/group
apache:x:100:
[root@localhost www]# id apache
uid=100(apache) gid=100(apache) groups=100(apache)
给工程站点目录授权apache的权限:
chown -R apache.apache /data/www/test/
指定apache系统虚拟用户创建ftp登录账户:sansan
[root@localhost www]# pure-pw list
[root@localhost www]# pure-pw useradd sansan -u apache -d /data/www/test
Password:
Enter it again:
[root@localhost www]# pure-pw mkdb
[root@localhost www]# cat /usr/local/pureftpd/etc/pureftpd.passwd
sansan:$6$92arGKjDIi/aODb0$SmyMeKUpsIYXVAqarsPH9xWqO4bdOqYKUXmP8TyUFlwTbTcvGhfJiW2pNMP56J3rHzSYp.mwCP8UB30MttMK01:100:100::/data/www/test/./::::::::::::
4.2登录系统新建虚拟用户www来创建ftp登录账户
[root@localhost home]# useradd www -s /sbin/nologin -M
[root@localhost home]# id www
uid=1003(www) gid=1003(www) groups=1003(www)
[root@localhost home]# chown -R www.www /data/www/test
[root@localhost home]# pure-pw list
sansan /data/www/test/./
[root@localhost home]# pure-pw useradd huahua -u www -d /data/www/test
Password:
Enter it again:
[root@localhost home]#
[root@localhost home]# pure-pw mkdb
[root@localhost home]# pure-pw list
sansan /data/www/test/./
huahua /data/www/test/./
[root@localhost home]# cat /usr/local/pureftpd/etc/pureftpd.passwd
sansan:$6$92arGKjDIi/aODb0$SmyMeKUpsIYXVAqarsPH9xWqO4bdOqYKUXmP8TyUFlwTbTcvGhfJiW2pNMP56J3rHzSYp.mwCP8UB30MttMK01:100:100::/data/www/test/./::::::::::::
huahua:$6$oUXu6U/V/UNM7K50$ztuftPKh7ZuzkHkY.XdNlQOmr6i6krlVQ0Mhsv7kuK5Qppvz440T55fRlssB5GrKkmMrSR220I5lU3yEA5Zsu/:1003:1003::/data/www/test/./::::::::::::
[root@localhost home]#
通过filezilla ftp工具登录ftp账户huahua
上传文件成功
