You can give permission to folder and all its contents using option -R
i.e Recursive permissions.
But I would suggest not to give 777 permission to all folder and it's all contents. You should give specific permission to each sub-folder in www directory folders.
Ideally, give 755
permission for security reasons to the web folder.
sudo chmod -R 755 /www/store
Each number has meaning in permission. Do not give full permission.
N Description ls binary
0 No permissions at all --- 000
1 Only execute --x 001
2 Only write -w- 010
3 Write and execute -wx 011
4 Only read r-- 100
5 Read and execute r-x 101
6 Read and write rw- 110
7 Read, write, and execute rwx 111
- First Number 7 - Read, write, and execute for the user.
- Second Number 5 - Read and execute for the group.
- Third Number 5 - Read and execute for others.
If your production web folder has multiple users, then you can set permissions and user groups accordingly.
