调整了用户组后，发现nginx报错：
2019/08/14 15:03:14 [error] 18667#0: *13 fastcgi sent in stderr: "php message: php warning: use of undefined constant mutheme_name - assumed 'mutheme_name' (this will throw an error in a future version of php) in /*** on line 15" while reading response header from upstream, client: *.*.*.22, server: www.uedbox.com, request: "get /*** http/1.1", upstream: "fastcgi://*.*.*.*", host: "www.uedbox.com"

*21685 open() "/usr/local/nginx/proxy_temp/8/00/0000000008" failed (13: permission denied) while reading upstream, client: 59.***.**.***, server: ******
提取关键信息
failed (13: permission denied) while reading upstream
地址为：/usr/local/nginx/fastcgi_temp/，跟过去看一下权限：
一眼就看出来了，用户与组不匹配，更新组:
sudo chown -r nobody:nobody /usr/local/nginx/fastcgi_temp sudo chown -r nobody:nobody /usr/local/nginx/proxy_temp
更新后的情况：
现在再打开相关连接，正常显示了。解决。
