Linux挂系统iso载镜像安装vsftpd服务
1.复制iso镜像到Linux系统 /home/iso/ 中
[root@localhost ~]# cd /home/iso/
[root@localhost iso]# ls
CentOS-8.4.2105-x86_64-dvd1.iso
2.创建挂载目标磁盘，挂载iso镜像，输入df -h查看挂载情况
[root@localhost /]# mkdir /mnt/cdrom
[root@localhost /]# mount /home/iso/CentOS-8.4.2105-x86_64-dvd1.iso /mnt/cdrom/
mount: /mnt/hgfs: WARNING: device write-protected, mounted read-only.
[root@localhost /]# df -h

/dev/loop0 9.3G 9.3G 0 100% /mnt/cdrom
[root@localhost /]#
3.在/mnt/cdrom挂载磁盘下，搜索ftp，使用rpm指令安装。
[root@localhost /]# cd /mnt/cdrom/
[root@localhost cdrom]#
[root@localhost cdrom]#
[root@localhost cdrom]# find -name "*ftpd*"
./AppStream/Packages/vsftpd-3.0.3-33.el8.x86_64.rpm
[root@localhost cdrom]#
[root@localhost cdrom]#
[root@localhost cdrom]# rpm -ivh ./AppStream/Packages/vsftpd-3.0.3-33.el8.x86_64.rpm

[root@localhost cdrom]#
4.检查是否安装成功
[root@localhost cdrom]# rpm -qa vsftpd
vsftpd-3.0.3-33.el8.x86_64
[root@localhost cdrom]#
5.检查vsftp服务状态，启动vsftp服务
[root@localhost ~]# systemctl status vsftpd
● vsftpd.service - Vsftpd ftp daemon
Loaded: loaded (/usr/lib/systemd/system/vsftpd.service; disabled; vendor preset: disabled)
Active: inactive (dead)
[root@localhost ~]#
[root@localhost ~]# systemctl enable vsftpd
[root@localhost ~]#
[root@localhost ~]# systemctl start vsftpd
[root@localhost ~]# systemctl status vsftpd
● vsftpd.service - Vsftpd ftp daemon
Loaded: loaded (/usr/lib/systemd/system/vsftpd.service; disabled; vendor preset: disabled)
Active: active (running) since Fri 2023-12-22 10:42:20 CST; 2s ago
Process: 4971 ExecStart=/usr/sbin/vsftpd /etc/vsftpd/vsftpd.conf (code=exited, status=0/SUCCESS)

Dec 22 10:42:20 localhost.localdomain systemd[1]: Started Vsftpd ftp daemon.
[root@localhost ~]#
[root@localhost ~]# ps -aux|grep vsftpd
root 4972 0.0 0.0 27056 424 ? Ss 10:42 0:00 /usr/sbin/vsftpd /etc/vsftpd/vsftpd.conf
root 13648 0.0 0.0 12136 1092 pts/0 S+ 11:31 0:00 grep --color=auto vsftpd
[root@localhost ~]#
6.创建用户ftptest
[root@localhost ~]# useradd ftptest
[root@localhost ~]#
[root@localhost ~]# passwd ftptest
Changing password for user ftptest.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.
[root@localhost ~]#
7.设置ftpd_anon_write -> on
[root@localhost ~]# getsebool -a |grep ftpuser
[root@localhost ~]# getsebool -a |grep ftp
ftpd_anon_write --> off
ftpd_connect_all_unreserved --> off
ftpd_connect_db --> off
ftpd_full_access --> off
ftpd_use_cifs --> off
ftpd_use_fusefs --> off
ftpd_use_nfs --> off
ftpd_use_passive_mode --> off
httpd_can_connect_ftp --> off
httpd_enable_ftp_server --> off
tftp_anon_write --> off
tftp_home_dir --> off
[root@localhost ~]#
[root@localhost ~]#
[root@localhost ~]#
[root@localhost ~]# setsebool -P ftpd_anon_write on
[root@localhost ~]# getsebool -a |grep ftp
ftpd_anon_write --> on
ftpd_connect_all_unreserved --> off
ftpd_connect_db --> off
ftpd_full_access --> off
ftpd_use_cifs --> off
ftpd_use_fusefs --> off
ftpd_use_nfs --> off
ftpd_use_passive_mode --> off
httpd_can_connect_ftp --> off
httpd_enable_ftp_server --> off
tftp_anon_write --> off
tftp_home_dir --> off
8.修改ftptest用户所属路径
//给需要共享的文件夹赋可读，可写权限
[root@localhost vsftpd]# chmod -R 777 /data/shartFiles/
//先查询ftptest的uuid
[root@localhost vsftpd]# id ftptest
uid=1001(ftptest) gid=1001(ftptest) groups=1001(ftptest)
[root@localhost vsftpd]#
//修改ftpuser的主路径，等同于直接修改 /etc/passwd文件
[root@localhost vsftpd]# usermod -d /data/shartFiles/ -u 1001 ftptest
[root@localhost vsftpd]#
9.修改/etc/vsftpd/user_list名单，添加ftptest,同时修改/etc/vsftpd/vsftpd.conf，添加以下参数至vsftpd.conf文件末尾
[root@localhost vsftpd]# vim /etc/vsftpd/user_list
# vsftpd userlist
# If userlist_deny=NO, only allow users in this file
# If userlist_deny=YES (default), never allow users in this file, and
# do not even prompt for a password.
# Note that the default vsftpd pam config also checks /etc/vsftpd/ftpusers
# for users that are denied.
root
bin
daemon
adm
lp
sync
shutdown
halt
mail
news
uucp
operator
games
nobody
ftptest
~
[root@localhost vsftpd]#vim /etc/vsftpd/vsftpd.conf
pam_service_name=vsftpd
userlist_enable=YES
allow_writeable_chroot=YES
pasv_min_port=30000
pasv_max_port=31000
userlist_file=/etc/vsftpd/user_list
userlist_deny=NO
10.千万不要在/etc/vsftpd/ftpusers里面添加ftptest用户，
