Error when starting nginx in systemctl mode under centos

Question

According to the log prompt, the directory /tmp/nginx/client_temp does not exist, but I checked many times and found that this directory exists. I directly operated with /usr/local/nginx/sbin/nginx and there was nothing Error message, I really can’t find the reason, please give me some guidance!!

The error is as follows:

[root@iZ94ss71ojfZ nginx]# systemctl status nginx
nginx.service - nginx - high performance web server
   Loaded: loaded (/etc/systemd/system/nginx.service; enabled)
   Active: failed (Result: exit-code) since Thu 2016-08-18 01:33:15 CST; 1s ago

Answer 1

If the directory exists, permission issues should be considered

Answer 2

It seems that there is a problem with the cache path configuration. The questioner can check why the configuration file has this path "/tmp/nginx/client_temp". If it is intentional, make sure that the path exists and has the corresponding Read and write permissions.

Answer 3

Try itnginx -c your_conf_file, if this works, it’s usually a permissions issue.
