I have centos 7.1. And I installed openjdk8 and openjdk-devel8. However, when I tried to compile in netbeans my jfx application I get package javafx.* does not exist.

I am running CentOS 7, and I am having problems with tcsh scripts. I have a simple script called quittest. #!/bin/tcsh echo "Simple Test" exit 0 When I run quittest from the terminal, I get "Simple Test" And it does not exit. I can Control+C to exit. I check on the status of this with: ps aux and it shows quittest with a state of S+ (foreground interruptible sleep). If I change this script to bash, or sh, it runs fine, and exits as expected. I cannot just switch to another shell, because my users have very complex scripts written with tcsh. We are replacing OpenSuSE 12.3 with CentOS 7. Tcsh

Recently I had the problem of starting a postgresql service with custom PGDATA path. It tried to look in the default data directory (/var/lib/pgsql/9.3/data/) which was not initialized and therefore triggered these errors. It appears the problem is that the service starter on Centos 7 strips all the environment variables, including PGDATA. Interesting thread on the issue Is there a way to configure service postgresql-9.3 start to use custom environment variables? Are there configuration files for services where these variables have to be defined? Thank you in advance! Thanks for the above
