這是DS白攝像頭，

我們自己的攝像頭，camera2沒找到nginx服務是怎么回事？文檔上也說要開啟nginx服務

我在camera2上搜索nginx

[root@RV1126_RV1109:/]# find . -name "*nginx*" ./etc/init.d/dS50nginx ./etc/logrotate.d/nginx # 可執行文件 ./etc/nginx # 文件夾 ./etc/nginx/nginx.conf ./etc/nginx/nginx.conf.default find: ./proc/622/task/623/fd/193: No such file or directory find: ./proc/622/task/633/fd/166: No such file or directory find: ./proc/622/task/633/fd/193: No such file or directory find: ./proc/622/task/702/fd/192: No such file or directory find: ./proc/622/task/716/fd/193: No such file or directory find: ./proc/622/task/717/fdinfo/166: No such file or directory find: ./proc/622/task/720/fd/193: No such file or directory find: ./proc/622/task/721/fdinfo/166: No such file or directory find: ./proc/622/task/725/fd/192: No such file or directory find: ./proc/622/task/725/fdinfo/193: No such file or directory find: ./proc/622/task/729/fdinfo/193: No such file or directory find: ./proc/622/task/732/fdinfo/192: No such file or directory find: ./proc/622/task/737/fdinfo/166: No such file or directory find: ./proc/622/task/737/fdinfo/192: No such file or directory find: ./proc/622/task/741/fdinfo/166: No such file or directory find: ./proc/622/task/747/fdinfo/166: No such file or directory find: ./proc/622/task/747/fdinfo/192: No such file or directory find: ./proc/622/task/751/fdinfo/166: No such file or directory find: ./proc/622/task/751/fdinfo/192: No such file or directory find: ./proc/622/task/752/fdinfo/193: No such file or directory find: ./proc/622/task/760/fdinfo/192: No such file or directory find: ./proc/622/task/761/fdinfo/193: No such file or directory find: ./proc/622/task/773/fd/166: No such file or directory find: ./proc/622/task/774/fdinfo/193: No such file or directory find: ./proc/622/task/778/fd/192: No such file or directory find: ./proc/622/task/779/fdinfo/193: No such file or directory find: ./proc/622/task/782/fd/193: No such file or directory find: ./proc/622/task/786/fd/166: No such file or directory find: ./proc/622/task/786/fd/192: No such file or directory find: ./proc/622/task/790/fd/192: No such file or directory find: ./proc/622/task/794/fd/166: No such file or directory find: ./proc/622/task/794/fd/192: No such file or directory find: ./proc/622/task/800/fdinfo/193: No such file or directory find: ./proc/622/task/804/fd/192: No such file or directory find: ./proc/622/task/808/fdinfo/193: No such file or directory ./usr/sbin/nginx # 一堆文件（包含nginx可執行文件）

嘗試手動啟動nginx

nginx -c /etc/nginx/nginx.conf [root@RV1126_RV1109:/]# nginx -c /etc/nginx/nginx.conf nginx: [alert] could not open error log file: open() "/var/log/nginx/error.log" failed (2: No such file or directory) 2021/10/19 15:28:41 [emerg] 1770#0: mkdir() "/var/tmp/nginx/client-body" failed (2: No such file or directory)

是nginx權限不夠？

查看nginx命令在哪：

[root@RV1126_RV1109:/usr/sbin]# type nginx nginx is /usr/sbin/nginx [root@RV1126_RV1109:/usr/sbin]#

切換到/usr/sbin

查看文件權限，發現nginx其他用戶組不具備寫權限

[root@RV1126_RV1109:/usr/sbin]# ls -lah total 11M drwxrwxr-x 2 root root 4.0K Jan 6 2021 . drwxrwxr-x 9 root root 4.0K Sep 24 02:06 .. ...省略 -rwxrwxr-x 1 root root 832K Feb 27 2021 nginx ...省略

給它賦權限

[root@RV1126_RV1109:/usr/sbin]# chmod 777 nginx

然后再執行：

nginx -c /etc/nginx/nginx.conf

還是不行，一樣的錯誤：

[root@RV1126_RV1109:/usr/sbin]# nginx -c /etc/nginx/nginx.conf nginx: [alert] could not open error log file: open() "/var/log/nginx/error.log" failed (2: No such file or directory) 2021/10/19 15:42:22 [emerg] 2434#0: mkdir() "/var/tmp/nginx/client-body" failed (2: No such file or directory)

20211020 DS后臺daemon運行的時候也沒看到nginx在跑，我把daemon禁用看看？

[root@RV1126_RV1109:/usr/sbin]# ps -aux | grep nginx root 911 0.0 0.0 2100 224 pts/0 S+ 16:26 0:00 grep nginx

你看都沒看到nginx在跑

禁用daemon

[root@RV1126_RV1109:/usr/sbin]# cd /opt/init/ [root@RV1126_RV1109:/opt/init]# [root@RV1126_RV1109:/opt/init]# vi run.sh

reboot重啟

。。。

20211022 得了，看這個吧，解決了
