vsftp安装
#解压 tar -zxf vsftpd-xx.tar.gz cd ./vsftpd-xx #vsftpd需要使用nobody来作为运行者,一般已经存在 useradd nobody
#安装时需要/usr/share/empty/ 作为临时目录,一般已经存在 mkdir /usr/share/empty/
#编译 make make install #如果make install没有安装文件,你可能需要手动执行下面的命令 #cp vsftpd /usr/local/sbin/vsftpd
#cp vsftpd.conf.5 /usr/local/man/man5
#cp vsftpd.8 /usr/local/man/man8 cd ./EXAMPLE/INTERNET_SITE cp vsftpd.conf /etc cp vsftpd.xinetd /etc/xinetd.d/vsftpd /etc/rc.d/init.d/xinetd restart
VSFTPD我是自己编译的,在论坛上许多文章说是编译使用的是XINETD模式,所以只要在/etc/xinet
d.d/vsftpd文件中,把disable=no改成YES就行了! 还有就是在/etc/vsftpd.conf文件添加listen=yes这样就改成了STANDALONE独立模式!
500 OOPS: could not bind listening IPv4 socket 错误:
因为xinetd已经启动了vsftpd,而vsftpd设置成了stardalone模式,所以,先 停止xinetd服务, service xinetd stop ,然后 /usr/local/sbin/vsftpd & 启动ftp服务
利用tar包安装和配置高可用性的vsftp
作者:梁尚锋 网名:好好先生
昨天看到有朋友说用tar包安装的vsftp不能用本地用户登录,感觉十分诧异。但自己也仅做过rpm
的,所以没有发言权。今天在自己机器上用tar包成功安装并配置了一个vsftp,现在把我的过程和
大家说一下,希望对大家有所帮助!
一、安装 [list:1af834efb8]1.下载最新的稳定版vsftpd-1.2.1.tar.gz 2.卸载原有的rpm的vsftpd rpm -e vsftpd 3.tar xvzf vsftpd-1.2.1.tar.gz 4.cd vsftpd-1.2.1 5.make 6.useradd nobody 7.mkdir /usr/share/empty 8.mkdir /var/ftp 9.useradd -d /var/ftp ftp 10.chown root.root /var/ftp 11.chmod og-w /var/ftp
说明:如果你象我一样原来有rpm的vsftp,只是卸载了,可以省略6-11步,如果原来没有安装vsft
p,请按部就班。 12.make install 13.vi /etc/xinetd.d/vsftpd 把disable=yes改成no,保存退出。然后service xinetd restart,OK!新装的vsftp已经可以工
作了! 说明:默认安装的vsftpd是以xinetd的方式启动的。你需要上述操作,一会儿,我们再来讲把它
改成独立启动的服务。 14.ftp 127.0.0.1 输入用户名ftp,密码直接回车,OK!已经可以连接了!输入quit退出。然后重新ftp 127.0.0.1
,输入本地用户和密码,却提示login faild!why?原来少一个本地用户认证的pam文件。 15.cp RedHat/vsftpd.pam /etc/pam.d/ftp(注意,没有这一步将不能使用本地用户登录!) 16.cp vsftpd.conf /etc/vsftpd.conf(现在,默认还是只能匿名用户登录) 17.vi /etc/vsftpd.conf 把anonmous_enable=YES改成NO(禁掉匿名链接,不安全) 把local_enable=YES前的注释去掉(打开本地用户连接的权限) 把write_enable=YES前的注释去掉(打开本地用户的写权限) 把local_umask=022前的注释去掉 service xinetd restart 18.再次测试 ftp 127.0.0.1 使用ftp用户空密码登录,将出现login faild 使用本地用户登录,OK!已经成功了!上传文件,也OK![/list:u:1af834efb8] 这样是不是就完事儿了?不是,做一个FTP,我们通常还需要一些特殊要求:比如一个用户我
只允许他下载,不允许他上传;另一个用户可以下载也可以上传,但是他不能删除文件,不能给文
件改名;另外,我还需要我的FTP使用非常规的端口,限制下载的速度,还需要一个管理员用户。
那怎么办?请看下面的部分!
二、高级配置 [list:1af834efb8] 1.使用独立服务 a.vi /etc/xinetd.d/vsftpd把disable=no还改成yes,不再需要它了! b.vi /etc/vsftpd.conf在结尾加上listen=YES c.service xinetd restart d./usr/local/sbin/vsftpd /etc/vsftpd.conf & OK!现在vsftp已经是独立启动的服务了! 2.使用非常规的端口(2121) a.vi /etc/vsftpd.conf 添加listen_port=2121,保存退出 b.killall -9 vsftpd c./usr/local/sbin/vsftpd /etc/vsftpd.conf & OK!现在用ftp 127.0.0.1将提示你连接被拒绝了(ftp:connect:Connetion refuesd)!然后ftp
127.0.0.1 2121输入用户名和密码,OK!可以登录! 3.实现不同用户不同权限 现在我们就来实现三个用户的不同权限:a.upload用户,可以上传下载,可以新建文件夹,但不
能删除文件和文件夹,不能重命名原有文件和文件夹;b.download用户,只能下载;c.admin用户
,管理员,可以上传,可以下载,可以新建文件夹,可以删除和更改文件和文件夹名。这些用户都
不能登录系统,并且用ftp连接时锁定在自己的家目录中不能进入系统文件夹。 a.cat << ! >logins.txt >upload >******* #upload用户的密码 >download >******* >admin >**************** >! 说明,此文本文件的格式是:单数行为用户名,偶数行为密码 b.db_load -T -t hash -f logins.txt /etc/vsftpd_login.db c.chmod 600 /etc/vsftpd_login.db d.cd vsftpd-1.2.1/EXAMPLE;cp VIRYUAL_USERS/vsftpd.pam /etc/pam.d/ftp.vu (进入你的解
包的源码目录,把虚拟用户的认证文件拷贝到/etc/pam.d/下) e.useradd -d /home/ftpsite virtual;chmod 700 /home/ftpsite;su - virtual -c "echo
hello>/homt/ftpsite/test.file(建立虚拟用户所要访问的ftp目录并设置仅 virtual用户访问的
权限和创建一个供下载实验的文件) f.vi /etc/vsftpd.conf在此文件中插入下面的配置语句 guest_enable=YES(启用虚拟用户) guest_username=virtual(将虚拟用户映射为本地virtual用户) pam_service_name=ftp.vu(指定PAM配置文件为ftp.vu) user_config_dir=/etc/vsftpd_user_conf(指定不同虚拟用户配置文件的存放路径) 保存退出 g.mkdir /etc/vsftpd_user_conf h.开放不同用户的不同权限 echo "anon_world_readable_only=NO">
/etc/vsftpd_user_conf/download(开放download用户的下载权限——只能下载;注意这个不地方
不要写成YES,否则将不能列出文件和目录) cp /etc/vsftpd_user_conf/download /etc/vsftpd_user_conf/upload vi /etc/vsftpd_user_conf/upload,添加下列行 write_enable=YES (增加写权限) anon_upload_enable=YES(增加上传权限) anon_mkdir_write_enable=YES (增加创建目录的权限) cp /etc/vsftpd_user_conf/upload /etc/vsftpd_user_conf/admin 增加一行: anno_other_writer_enable=YES(增加管理员用户的删除/重命名的权限) i.测试 killall -9 vsftpd;/usr/local/sbin/vsftpd /etc/vsftpd.conf & ftp 127.0.0.1 2121 以用户名download和你设置的密码登录,ls,可以看到文件,下载,成功!put一个文件,提
示 Permission denied。rename test.file同样权限被拒绝;delete test.file同样不成功! 输入quit退出,以upload用户登录,OK!可以上传,下载,mkdir lsf,提示“/lsf" created
;rename lsf lsf1提示Permission denied,删除文件同样不成功! 输入quit退出,以admin用户登录,可以有上述所有权限,然后rmdir lsf,提示Remove
directory o [eration successful;delete test.file提示Delete operation successful!OK,大
功告成了! 4.还有限速,限制同一个IP的连接数,限制最大连接数等,我在另外的文章中已经写过,在此不
