use_localtime=YES
EOF
  mkdir -p /etc/vsftpd/chroot_list
  mkdir -p /data
  useradd -d /data/ftp/ ftpadmin
  chown -R ftpadmin /data/ftp
  systemctl restart vsftpd
  echo "vsftpd Installation successful "
  echo " adopt  systemctl [status|start|stop|restart|enable|disable] vsftpd  To operate "
  echo " Successfully created user ftpadmin, adopt  passwd ftpadmin  Configure the password "
}

#  close selinux
disableSeLinux(){
  # -s file　 The file size is not 0 Time is true 
  if [ -s /etc/selinux/config ] && grep 'SELINUX=enforcing' /etc/selinux/config; then
    #  take SELINUX=enforcing Replace with SELINUX=disabled
    sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
    setenforce 0

  fi
}


ls /usr/lib/systemd/system/vsftpd.service
status=$?
# 0 Indicates that the service has been found   Not 0 It means there is no service   Judge equality with spaces 
if [ $status == 0 ]; then
  echo "vsftpd Installation successful "
  echo " adopt  systemctl [status|start|stop|restart|enable|disable] vsftpd To operate "
else
  disableSeLinux
  installVsftpd
