openstack production deployment

Tomcat with Tomcat user GreenTomcat really is very concise, belongs to the pure green software, download directly down the decompression is complete installation. A little configuration can be executed smoothly, detailed configuration steps to see the $catalina_home/running.txt file, said very clearly. The rationale is that Tomcat has done a script bin/catalina.sh that controls start and stop. The only prerequisite for this script to execute smoothly is to know the JDK installation path. Tomcat

things compared to WSGI. Uwsgi performance is very highThe main features of UWSGI are as follows Ultra-fast Performance Low memory footprint (about half of Mod_wsgi measured as apache2) Multi-app Management (finally don't have to worry about which port the next app is better-.-) Detailed logging capabilities (can be used to analyze app performance and bottlenecks) Highly customizable (memory size limit, service Restart after a certain number of times, etc.) Al
