linux下vsftpd的安装及配置使用详细步骤(推荐)

      设置命令：setsebool -p xxxxxx on

[root@bogon ~]# setsebool -P allow_ftpd_full_access on
[root@bogon ~]# setsebool -P ftp_home_dir on

1.4  设置或关闭防火墙

因为ftp默认的端口为21，而centos默认是没有开启的，所以要修改iptables文件

设置：vi /etc/sysconfig/iptables

在行上面有22 -j ACCEPT 下面另起一行输入跟那行差不多的，只是把22换成21，然后：wq保存。

还要运行下,重启iptables

重启：service iptables restart

关闭防火墙：service iptables stop

禁用防火墙重启：chkconfig iptables off

1.5  启动vsftpd

命令：service vsftpd start
