nginx 錯誤總結
1.nginx -s stop出現
nginx: [alert] could not open error log file: open() "/usr/local/var/log/nginx/error.log" failed (13: Permission denied)
sudo chmod a+w /usr/local/var/log/nginx/*.log
sudo chmod a+w /usr/local/var

2.nginx -s stop出現
nginx: [alert] kill(2040, 15) failed (1: Operation not permitted)
sudo nginx -s stop
3. nginx -s reload出現
nginx: [error] open() "/usr/local/var/run/nginx.pid" failed (2: No such file or directory)
重新啟動nginx(在nginx啟動時候會生成nginx.pid檔案，在nginx關閉會刪除該檔案，nginx重啟也會去查詢該檔案，若找不到，啟動nginx重新生成該檔案)
4.sudo nginx 啟動出現
nginx: [error] open() "/usr/local/var/run/nginx.pid" failed (2: No such file or directory)
刪除/usr/local/var/run/nginx.pid檔案
重新啟動
