tar -xzvf vsftpd-3.0.3.tar.gz 
cd vsftpd-3.0.3


 vim builddefs.h
#ifndef VSF_BUILDDEFS_H
#define VSF_BUILDDEFS_H
#define VSF_BUILD_TCPWRAPPERS
#define VSF_BUILD_PAM
#undef VSF_BUILD_SSL
#endif /* VSF_BUILDDEFS_H */


修改显示
sed -i 's/UTF8 ON/DISABLE UTF8 ON/g' opts.c


编译安装
make && make install


mkdir /etc/vsftpd/
cp vsftpd.conf /etc/vsftpd/       #配置文件     
cp RedHat/vsftpd.pam /etc/pam.d/ftp #PAM认证文件
sed -i 's/lib\//lib64\//g' /etc/pam.d/ftp


修改配置文件
vi /etc/vsftpd/vsftpd.conf
anonymous_enable=No #不允许匿名用户使用  
local_enable=YES  #允许本地用户可用 
write_enable=YES  #写操作  
dirmessage_enable=YES  #需要显示某目录下文件信息
max_clients=100  #FTP服务器最大承载用户数 
#listen_port=8080    #更改监听端口9000 默认是21
#改被动模式
pasv_min_port=30000
pasv_max_port=30100
local_root=/FTP             #修改FTP根目录为/FTP
chroot_local_user=YES       #禁止切换出FTP根目录


启动并查看vsftpd
/usr/local/sbin/vsftpd &
netstat -tunlp | grep 21
/usr/local/sbin/vsftpd -v
cp /usr/local/sbin/vsftpd /usr/sbin/vsftpd


制作启动脚本
vim /etc/xinetd.d/vsftpd
