I have installed PrizmDoc based on the documentation against a clean CentOS 7/RedHat 7 system, and Prizm services starts and is showing healthy. However, one of two issues are occurring:
If you cannot view HTML or picture files but can view PDF files, it is often due to specific required libraries not being installed. The following procedure can be executed on CentOS/RedHat 7 to ensure all required PrizmDoc libraries are installed.
Stop the Prizm service: sudo /usr/share/prizm/scripts/pccis.sh stop
sudo /usr/share/prizm/scripts/pccis.sh stop
Copy and paste all of the library installers into a terminal and wait for them to finish:
yum install -y libbz2* libc* libcairo* libcups* libdbus-glib-1* libdl* libexpat* libfontconfig* libfreetype* libgcc_s* libgif* libGL* libjpeg* libm* libnsl* libopenjpeg* libpixman-1* libpng12* libpthread* librt* libstdc++* libthread_db* libungif* libuuid* libX11* libXau* libxcb* libXdmcp* libXext* libXi* libXinerama* libxml2* libXrender* libXtst* libz* linux-vdso*
Restart the server.
If you cannot view PDF, Excel, or Word documents but can view HTML and Picture files, this is often due to installing the Generic PrizmDoc installer, which ends in either client_x86_64.tar.gz or server_x86_64.tar.gz. To resolve this issue you will need to re-install using the links that end in client_x86_64.rpm.tar.gz and server_RHEL7.tar.gz.
