Suggestion to have multiple sites share a common shared directory

[gilbert]

Hi,

The client has a dedicated server so security is not an issue of access between the sites is not an issue and or all sites on the server.

user for site that initiates the copy is vu2001
when I su vu2001
issue
cp /var/www/virtual/site1.com/htdocs/copyTest/pumadisc.jpg /var/www/virtual/site2.com/htdocs/copyTest/

I get
cp: accessing `/var/www/virtual/site2.com/htdocs/copyTest/': Permission denied

ls -l /var/www/virtual/
drwxrwx--- 8 vu2010 www-data 4096 2009-09-02 00:26 site2.com
ls -l /var/www/virtual/site2.com/
drwxrwxr-x 5 vu2010 www-data 4096 2009-08-31 15:12 htdocs
ls -l /var/www/virtual/site2.com/htdocs
drwxrwxr-x 2 vu2010 www-data 4096 2009-08-31 15:12 copyTest


Would I have to add vu2001 to www-data group is that a good solution?

Thanks,
Gilbert.
