linux服务器配置
安装ftp
yum install vsftpd
启动服务
service vsftpdstart
开机启动
chkconfig --level 35 vsftpd on
设置权限
vi /etc/vsftpd/vsftpd.conf
将配置文件中”anonymous_enable=YES“改为 “anonymous_enable=NO”
放开Chroot_local_user=yes
添加用户
useradd ftpadmin-s/sbin/nologin 默认指向home/ftpadmin目录
指向其他目录useradd ftpadmin -s /sbin/nologin -d /www(其他目录)
设置ftpadmin密码
passwd ftpadmin输入两次
地址栏中输入 ftp://IP 来连接FTP服务器，根据提示输入账户密码
出现553 Could not create file解决方法
1.chmod -R 777 文件目录 修改vsftp的配置文件/etc/vsftpd.conf文件 local_root=/var/ftp
2.setsebool -P ftpd_disable_trans 1 重启
