Suggested Improvements

SELinux may prevent /usr/sbin/php-fpm from accessing tcp_socket port 25321 with name_connect access.

Text Proposals

!!! note "If you plan to use JDisc, you should tell SELinux that php-fpm is allowed to access the JDisc port. To do this, assign the port to a suitable SELinux port type like:

sudo semanage port -a -t postgresql_port_t -p tcp 25321
