Creating Soft Links

...
To ensure soft links from Tomcat to PhixFlow directories are secure, configure the context.xml file as follows:
- Edit
/opt/tomcat/conf/context.xml - Find the line:
<Resources cachingAllowed="true" cacheMaxSize="1000000" /> - Replace it with:
<Resources allowLinking="true" cachingAllowed="true" cacheMaxSize="1000000" />
Creating Soft Links
In the following commands:
path/folder_nameis the full path to the directory to which you want to linksoft_link_nameis the directory name you want to use as a soft link.
On Linux
...
create soft links using the ln command
ln -s path/folder_name soft_link_nameIf a file path includes spaces, enclose it in double-quotes.

sudo ln -s /opt/phixflow/data/ /opt/tomcat/webapps/phixflow/datalink |
On Windows
...
create soft links using the mklink command
...
By default, the mklink command creates links to specific files
...
. To link to a directory, use the /D option.
mklink /D soft_link_name path/folder_name

mklink /D c:\app\tomcat\webapps\phixflow\datalink c:\path\phixflow\data |

Securing Soft Links
To ensure soft links from Tomcat to PhixFlow directories are secure, configure the context.xml file as follows:
- Edit
/opt/tomcat/conf/context.xml - Find the line:
<Resources cachingAllowed="true" cacheMaxSize="1000000" /> - Replace it with:
<Resources allowLinking="true" cachingAllowed="true" cacheMaxSize="1000000" />
Example Soft Links
In the following example, Tomcat has a soft link called images-link to a files/images directory in PhixFlow.
| OS | Soft link in a Tomcat directory | points to → | PhixFlow server directory containing files |
|---|---|---|---|
| Linux |
...
<path>/tomcat/webapps/phixflow/images-link |
| |
| Windows | <path>\tomcat\webapps\phixflow\ | <path>/phixflow/ |
You can also create soft links within the PhixFlow server, for example to simplify paths.
| OS | Soft link in Tomcat directory | points to → | Soft link in PhixFlow server | points to → | Directory containing files |
|---|---|---|---|---|---|
| Linux |
...
<path>/tomcat/webapps/phixflow/proj1-images |
| /opt/phixflow/allprojects/apps/project1/ | |
| Windows | <path>\tomcat\webapps\phixflow\proj1-images | <path>/phixflow/images/project1/ | <path>/phixflow/ |
