nginx問題集

nginx啓動關閉操做

nginx -s reload：修改配置後從新加載生效
nginx -s reopen：從新打開日誌文件
nginx -t -c /path/to/nginx.conf 測試nginx配置文件是否正確
    關閉nginx：
nginx -s stop:快速中止nginx
                quit：完整有序的中止nginx
    其餘的中止nginx 方式：
ps -ef | grep nginx
kill -QUIT 主進程號：從容中止Nginx
kill -TERM 主進程號：快速中止Nginx
pkill -9 nginx：強制中止Nginx
啓動nginx:
nginx -c /path/to/nginx.conf
平滑重啓nginx：
kill -HUP 主進程號

五、前臺Failed to load resource: net::ERR_CONTENT_LENGTH_MISMATCH，後臺錯誤2015/05/30 00:11:53 [crit] 8808#0: *60 open() "/var/cache/nginx/proxy_temp/2/01/0000000012" failed (13: Permission denied)

proxy_temp目錄的group設置爲nginx，並賦予rwx權限

六、nginx響應超時upstream timed out (110: Connection timed out) while reading response header from upstream

https://blog.csdn.net/u014218983/article/details/81217032

proxy_connect_timeout 默認值60s, nginx鏈接到後端服務器的鏈接超時時間，發起握手等候響應超時時間。 proxy_read_timeout 鏈接成功後，等候後端服務器響應時間。其實已經進入後端的排隊之中等候處理（也能夠說是後端服務器處理請求的時間）。 proxy_send_timeout 後端服務器數據回傳時間，就是在規定時間以內後端服務器必須傳完全部的數據。
