Build a high-performance and high-availability Tomcat server from scratch

Build a high-performance and high-availability Tomcat server from scratch

Objectives:

Tomcat + Nginx + Memcached

Ubuntu 16.04 passed the 64-bit Test

Dynamic/static classification, load balancing, cluster, Javolution serialization, high performance, high availability

Configuration environment (currently the latest stable version ):
Jdk-8u131-linux-x64
Apache -- tomcat-8.5.14
Nginx-1.12.0
Memcached-1.4.36

Preface:

I originally planned to configure the kryo serialization framework, but it was not successful. I had to use Javolution.
If the final failure is found, the problem usually occurs in Tomcat. Check the log to solve the problem.
You can deploy multiple projects under tomcat, and the categories are still dynamic and static.
Nginx is configured to assign the suffix of jsp, servlet, And do files to Tomcat for processing. You can add
If you do not use the root account to run nginx, The nginx user configuration is useless.
Tomcat and nginx are all optimized. You can directly put them in Tomcat/webapps without modifying any content of the original project.

Process:

The process is long. Please be careful
