Method one: Modify the configuration file add a line nginx.conf user root
Method two: Configuration /etc/fdfs/mod_fastdfs.conf
url_have_group_name = false changed to true (using the group name to access)
The last two methods have to perform nginx -s reload to reload the configuration file to take effect, and finally we can visit
Note that if both are not used the effect is likely to be a firewall is not turned off
Turn off the firewall:
service firewalld stop // stop firewall
service firewalld disable // permanently stop
If that does not make it completely off the firewall and then perform a setenforce 0 (turn off the built-in firewall, executing the sentence does not appear before the entry into force of a 404 error)
