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

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。

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
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/./::::::::::::
通过Xftp客户端登录ftp账户sansan
