Tomcat Grayscale release shell script (from the network can be referenced)

Java Grayscale Script

Use scripting considerations:
1, the publishing machine needs to be able to resolve the Web server hostname, and configure SSH communication
2, the variables in the directory and users and other information needs to create their own, the script does not make judgments to create their own. My Web server is deployed using Ansible, and the relevant directories and users are created automatically.
3. The code is deployed using tag, but the code update is controlled using a soft connection, and the rollback switches to the previous soft connection
4, because Java is a compiled language, we use MAVEN to compile, so we need to install the MAVEN environment.
5, about the Environment profile: the configuration file for their own manual maintenance, each time is to delete the Git repository pull down the configuration file, the corresponding environment of the code files copied into the compilation directory to compile.
