#执行
systemctl status nginx.service
#如果出现如下错误
  Process: 35783 ExecStart=...nginx/sbin/nginx(code=exitedstatus=203/EXEC)
  nginx.service: Control process exited, code=exited status=203
  systemd[1]: nginx.service: Failed with result 'exit-code'.
  localhost.localdomain systemd[1]: Failed to start nginx.


journalctl -xe

#如果看到如下信息     
  If you believe that systemd should be allowed execute access on the>
  Then you should report this as a bug.
  You can generate a local policy module to allow this access.
  Do allow this access for now by executing:
  # ausearch -c '(nginx)' --raw | audit2allow -M my-nginx
  # semodule -X 300 -i my-nginx.pp


#解决方法
setenforce 0
