我们自己的摄像头，camera2没找到nginx服务是怎么回事？文档上也说要开启nginx服务

我在camera2上搜索nginx

./usr/sbin/nginx	# 一堆文件（包含nginx可执行文件）

尝试手动启动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权限不够？

查看nginx命令在哪：

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

切换到/usr/sbin

查看文件权限，发现nginx其他用户组不具备写权限

[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

给它赋权限

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

然后再执行：

nginx -c  /etc/nginx/nginx.conf

还是不行，一样的错误：

[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后台daemon运行的时候也没看到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

你看都没看到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重启

。。。

20211022 得了，看这个吧，解决了
