ftp服务器搭建

注：ip=172.29.156.212

安装

yum install -y vsftpd
systemctl start vsftpd
systemctl status vsftpd

修改配置文件
--------------------------------匿名用户登录-------------------------

vim /etc/vsftpd/vsftpd.conf
anonymous_enable=YES
anon_umask=022
anon_upload_enable=YES
anon_mkdir_write_enable=YES
anon_other_write_enable=YES
local_enable=YES
write_enable=YES
local_umask=022
dirmessage_enable=YES
xferlog_enable=YES
connect_from_port_20=YES
xferlog_std_format=YES

----------------------本地用户登录验证------------------

anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022
dirmessage_enable=YES
xferlog_enable=YES
connect_from_port_20=YES
xferlog_std_format=YES
listen=NO
listen_ipv6=YES
pam_service_name=vsftpd
userlist_enable=YES

创建用户设置密码

adduser -s /bin/false -d /var/ftp/ftp1 ftp1
passwd ftp1
adduser -s /bin/false -d /var/ftp/ftp2 ftp2
passwd ftp2
# 设置的密码为Kylin123，不要使用root用户权限太大
# 也可以直接创建用户useradd ftp3，客户端显示的时用户的目录，如/home/ftp3
chmod 777 /var/ftp/ftp1

登录的用户不可以在这两个文件中记录

/etc/vsftpd/ftpusers  
/etc/vsftpd/user_list

关闭防火墙并重启

#关闭防火墙
systemctl stop firewalld.service
#永久禁止防火墙
systemctl disable firewalld.service
#重启
systemctl restart vsftpd
systemctl enable vsftpd
#查看状态
systemctl status vsftpd

#----------
setsebool -P ftpd_full_access=on

或：关闭SELinux
# vi /etc/selinux/config
将 SELINUX=XXX -->XXX 代表级别
改为
SELINUX=disabled
然后重启系统，或者执行命令：setenforce 0
#----------------

下载ftp

yum install -y ftp
