After the server downloads a good ftp, try using the default configuration anonymous login try, but always being given, several possibilities are summarized below.
21 port 1.FTP not let go, solutions
//关闭防火墙
systemctl stop firewalld.service
#停止firewall
systemctl disable firewalld.service
#禁止firewall开机启动
//或者防火墙添加FTP服务
firewall-cmd --permanent --zone=public --add-service=ftp
firewall-cmd --reload
2. Since the default configuration is not a passive mode, but the access is detected in a window ftp client must use passive mode (I is for this reason), solution:
On the IE browser settings to open the FTP folder. Open IE browser, select Settings> Internet Options> Advanced. Check the Enable FTP folder view, uncheck the Use Passive FTP.
- Change the port, but did not increase
Open the client computer, enter the path bar ftp: // server IP address: FTP port (if you do not fill port 21 is the default access port), for example: ftp://0.0.0.0:20 . Pop up a user name and password dialog configuration is successful, the correct user name and password, you can manipulate files on FTP appropriate permissions.
- SELinux reasons
//临时关闭
setenforce 0 # 设置SELinux 成为permissive模式 （关闭SELinux）
setenforce 1 # 设置SELinux 成为enforcing模式 （开启SELinux）
//或者永久关闭selinux
vi /etc/selinux/config
# SELINUX=enforcing
# 注释掉
# SELINUXTYPE=targeted
# 注释掉
SELINUX=disabled
# 增加
:wq! #保存退出
setenforce 0
//或者修改selinux的配置
getsebool -a | grep ftp
setsebool -P ftpd_full_access on
