There are many commonly used binaries already available on our shared hosting servers for your use. To search for a specific binary to see if it is installed before trying to install from source, simply use the
command via SSH. To see if PHP6 is installed for instance, you would type
and press ENTER. The output will show you the paths to binary files, library files, etc. if installed.
It may be possible for source code to be compiled on Linux shared hosting for customers that have packages supporting SSH access. Installation from source code will not apply to the entire hosting server as access is restricted to retain integrity of our services. Installation via source code will need to be contained within your own web space. Because of this, it is likely that to successfully complete an install via source code, some environment variables will need to be altered for the installation.
Installation via source code is not covered by 1&1's support and no listening service is permitted to be installed. Only a few select ports are open to 1&1 servers from the outside to provide proper functionality of our offered services. Listening services manually installed will not be able to receive traffic even if successfully installed.
