故障現(xiàn)象：

外網(wǎng)訪問頁面顯示不正常，Template Error!

?

接到反饋后，遠程到服務(wù)器，執(zhí)行service nginx restart ，提示磁盤滿，無法繼續(xù)。

查看磁盤占用情況，磁盤/目錄占用100%,磁盤空間滿。

執(zhí)行

find / -size +100M -exec ls -lh {} \;

查找100M以上的文件，發(fā)現(xiàn)主要大的是NGINX的日志：

一天的NGINX日志大到30多個G，太離譜了！！！

?

切割文件的最后Ｎ行到新的文件中

tail -n 1000 access.log >> 111.log

這樣做，主要是太大的文件我用VI無法打開。

對比正常的其它服務(wù)器：
http://10.10.14.199/dsideal_yy/golbal/getValueByKey?key=common.rongyun.suffix
{"common.rongyun.suffix":"_199"}

繼續(xù)查看此服務(wù)器：
http://10.24.0.7:7777/dsideal_yy/golbal/getValueByKey?key=common.rongyun.suffix
{"common.rongyun.suffix":"_zztez"}

也不是404啊！！！！

?

訪問一下http://10.24.0.7,居然可以訪問的到！！！！！！還顯示welcome to Nginx!!!!我們是7777的端口啊！！！

查看一下80端口是什么東東在使用：

yum install lsof
lsof -i tcp:80

[root@bogon conf]# lsof -i tcp:80 ?
COMMAND??? PID USER?? FD?? TYPE???? DEVICE SIZE/OFF NODE NAME
nginx?? 243175 root?? 10u? IPv4 2358009951????? 0t0? TCP *:http (LISTEN)
nginx?? 243176 root?? 10u? IPv4 2358009951????? 0t0? TCP *:http (LISTEN)
nginx?? 243178 root?? 10u? IPv4 2358009951????? 0t0? TCP *:http (LISTEN)
nginx?? 243179 root?? 10u? IPv4 2358009951????? 0t0? TCP *:http (LISTEN)
nginx?? 243180 root?? 10u? IPv4 2358009951????? 0t0? TCP *:http (LISTEN)

根據(jù)pid查文件位置：
ps 243175

[root@bogon conf]# ps 243175
?? PID TTY????? STAT?? TIME COMMAND
243175 ???????? Ss???? 0:00 nginx: master process /usr/local/openresty/nginx/sbin/nginx -c /usr/local/openresty/nginx/conf/nginx.conf

到這里很顯示了，還是這個配置文件有問題，里面配置了兩個端口：7777和80

?

server {listen 80;server_name office.edusoa.com;location ^~ /yjj/ {proxy_pass http://221.194.113.150/; }location ^~ /pingli/ {proxy_pass http://61.134.47.35:9999/; }}

這個東東明顯就是垃圾，注釋掉，并手工刪除超大的日志文件，世界清靜了~

?

回頭想想，這是兩個問題：

1、即然配置了7777，為什么還保留了80，這是明確的錯誤。

2、就算是同時配置了80和7777，那個大量的404錯誤從哪里來？？

{"ip":"10.24.0.6","request_method":"GET","request_uri":"/dsideal_yy/golbal/getValueByKey","args_get":"key=common.rongyun.suf
fix","args_post":"-","browser":"Mozilla/5.0 (Windows NT 5.1; rv:5.0) Gecko/20100101 Firefox/5.0","cookie":"-","request_time"
:"12/Jan/2018:07:52:15 +0800","http_status":"404"}

很明顯，是10.24.0.6這臺機器上來的，這是一臺windows主機，是處理程序發(fā)過來的請求，它在干什么？為什么不去訪問7777的端口？？

補充：

1、在訪問時，發(fā)現(xiàn)訪問不了，直接while true了，這里應(yīng)該是停止或者休息一會。

2、處理程序在訪問全局變量時居然沒有加上端口！！！！！造成繼續(xù)訪問80，這就是幾個錯誤集中在一起，導(dǎo)致了問題出現(xiàn)，血的教訓(xùn)！！！
