Linux 搭建 FTP，用于企业网关批量升级

1、安装 FTP

# CentOS 7: yum -y install vsftpd
# Ubuntu： apt-get install vsftpd

2、创建 FTP 默认目录，用于存放升级文件

# ll /home/ftp/
total 60180
drwxrwxrwx 2 ftp  ftp      4096 May 19 19:48 ./
drwxr-xr-x 6 root root     4096 May 19 18:37 ../
-rw-rw---- 1 bp   bp   61612896 May 19 14:24 MSG2200E-4V_SYSTEM_3.20.261_20200430.bin

3、编辑配置文件

# 备份原配置文件
root@ubuntu:~# mv /etc/vsftpd.conf /etc/vsftpd.conf.bak

# 编辑配置文件，直接复制以下配置内容即可
root@ubuntu:~# vi /etc/vsftpd.conf
root@ubuntu:~# cat /etc/vsftpd.conf
local_root=/home/ftp
anon_root=/home/ftp
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
tcp_wrappers=YES
listen=YES
pam_service_name=vsftpd
chroot_local_user=YES
chroot_list_enable=YES
chroot_list_file=/etc/vsftpd/chroot_list

# 按需创建用户列表
root@ubuntu:~# cat /etc/vsftpd/chroot_list 
bp
ftptest

4、重启服务

root@ubuntu:/home/ftp# service vsftpd restart
root@ubuntu:/home/ftp# service vsftpd status
