I need to make sure that all users in a group have read/write access to all files in a shared folder, old and new files.
First, make sure that all existing files and folders are in the group
chgrp group . -R
And all new files and folders must be in the same group too
chmod g+s . -R
Finally, the files created by all users must have read/write permissions to the group. We must ensure what this command is run whenever a user logs on system.
We can ensure that by adding this line to /etc/bashrc.
I have a brand new VPS on intovps.com, that runs on overvz.
My OS is Linux Ubuntu 12.04 and i needed to install tomcat-solr. By running
sudo apt-get install ca-certificates-java
I was getting the error:
Could not create the Java virtual machine.
By following this link i found that oracle java7 works perfectly on Ubuntu over openvz.
All I needed to do was:
sudo apt-get purge openjdk*
sudo add-apt-repository ppa:eugenesan/java
sudo apt-get update
sudo apt-get install oracle-java7-installer
- Now the tomcat-solr will work as excpected
sudo apt-get install tomcat-solr
Hope it works, good luck to your new server :)
