根据日志的提示是 /tmp/nginx/client_temp 这个目录不存在,但是我反复检查了好多遍,这个目录是存在的,我直接以 /usr/local/nginx/sbin/nginx 进行操作没有任何错误提示,实在是找不到原因在哪了,求大神指点迷津!!
错误如下:
[root@iZ94ss71ojfZ nginx]# systemctl status nginx

目录如果存在，应该要考虑权限问题
看着像是缓存的路径配置有问题，题主可以查看配置文件为啥会有这个路径"/tmp/nginx/client_temp"，如果是有意为之，则要确保该路径存在、并且有相应的读写权限。
试试nginx -c your_conf_file，如果这个能成功，一般是权限问题。
