Hi All,
I have hosted a nginx server instance and the temp directories are created
under /etc/nginx/
$ ls -ld /etc/nginx/*_temp
drwx------ 2 nobody root 4096 Mar 16 15:21 /etc/nginx/client_body_temp
drwx------ 2 nobody root 4096 Mar 16 15:21 /etc/nginx/fastcgi_temp
drwx------ 2 nobody root 4096 Mar 16 15:21 /etc/nginx/proxy_temp
drwx------ 2 nobody root 4096 Mar 16 15:21 /etc/nginx/scgi_temp
drwx------ 2 nobody root 4096 Mar 16 15:21 /etc/nginx/uwsgi_temp
And I updated to a newer version of nginx which runs in "nginx" user context
and after that these directory ownership is getting changed to nginx:root but
the issue is, it happens only on these top directories and not directories
within these temp directories.
I did strace on the same to confirm my theory.
mkdir("/etc/nginx/client_body_temp", 0700) = -1 EEXIST (File exists)
stat("/etc/nginx/client_body_temp", {st_mode=S_IFDIR|0700, st_size=4096, ...})
= 0
chown("/etc/nginx/client_body_temp", 997, -1) = 0
mkdir("/etc/nginx/proxy_temp", 0700) = -1 EEXIST (File exists)
stat("/etc/nginx/proxy_temp", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0
chown("/etc/nginx/proxy_temp", 997, -1) = 0
mkdir("/etc/nginx/fastcgi_temp", 0700) = -1 EEXIST (File exists)
stat("/etc/nginx/fastcgi_temp", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0
chown("/etc/nginx/fastcgi_temp", 997, -1) = 0
mkdir("/etc/nginx/uwsgi_temp", 0700) = -1 EEXIST (File exists)
stat("/etc/nginx/uwsgi_temp", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0
chown("/etc/nginx/uwsgi_temp", 997, -1) = 0
mkdir("/etc/nginx/scgi_temp", 0700) = -1 EEXIST (File exists)
stat("/etc/nginx/scgi_temp", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0
Now the issue is, why chown happens only on top directory and not recursively
on all files and directories inside them? Is this a bug or is it fixed in
latest version of nginx?
I'm currently using nginx-1.22.0. Any help would be appreciated. Thanks.
