Setting the Talend JobServer directory permissions

About this task

If you have already started Jobs from this server, it is recommended to remove the directory <jobserver_path>/TalendJobServerFiles to avoid unexpected authorizations on already deployed Jobs or cached files.

Procedure

Add each user allowed to run tasks (for example, user called subuser) to the 'root' group, as well as to the group of the user who owns the parent directories of Talend JobServer (for example, group of the user called my_user).
Example
```
> sudo usermod -a -G myuser_group subuser
> sudo usermod -a -G root subuser
```
Give the execute permission to myuser_group in each of the following directories by executing chmod g+rx /<directory_path>.
Example
```
/opt
/opt/talend
/opt/talend/Talend-JobServer
/opt/talend/Talend-JobServer/TalendJobServersFiles
/opt/talend/Talend-JobServer/TalendJobServersFiles/cache
/opt/talend/Talend-JobServer/TalendJobServersFiles/cache/lib
```
The parent folders of the Talend-JobServer folder in this example are for demonstration purposes only. They highlight the necessity of the execute permission at each level of the directory structure to ensure correct functioning.
Information noteNote: The READ authorization for the group is only required for deployed files.
