ziqew / vagrant-java-server

Creates server development environment for java developer

Prerequisite

• Install Virtualbox
• Install Vagrant
• Navigate to project you would like to work

    cd ~/yourWorkingProject
    vagrant init tcthien/java-dev-server
    vagrant up

Using this vagrant effectively

• Mapping your source folder & maven repository folder from host to guest

    cd ~/yourWorkingProject
    vim Vagrantfile
    # Copy following to your vagrant file --------------------------------
    # 
    Vagrant.configure("2") do |config|
      config.vm.box = "tcthien/java-dev-server"

      config.vm.synced_folder "C:/Users/admin/.m2/repository", "/share/mavenRepo"
      config.vm.synced_folder "", "/share/source"
      
      # MySQL Port
      config.vm.network "forwarded_port", guest: 3306, host: 3306
      # Cassandra Port
      config.vm.network "forwarded_port", guest: 9042, host: 9042
      config.vm.network "forwarded_port", guest: 7000, host: 7000
      config.vm.network "forwarded_port", guest: 7001, host: 7001
      config.vm.network "forwarded_port", guest: 9160, host: 9160
      
      config.vm.provider "virtualbox" do |vb|
         vb.memory = "4096"
         vb.name = "codelab-server"
      end
    end
    # End file -----------------------------------------------------------
    

• Create settings.xml in ~/.m2 and update your maven repository points to /share/mavenRepo
• Access to your source file in

    cd /share/source

Environment for Java Developer

• Download JDK directly

    #java8
    wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u112-b15/jdk-8u112-linux-x64.tar.gz

    #java7
    wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/7u79-b15/jdk-7u79-linux-x64.tar.gz

• Cassandra 3.9
  • Cassandra located under ~/bin/
  • Execute following to start Cassandra server cassandra -f
  • Create user

cqlsh localhost -u cassandra -p cassandra
create user root with password 'root' superuser;

CREATE KEYSPACE keyspaceName WITH replication = {'class':'SimpleStrategy', 'replication_factor' : 3};

      • sudo service mysql restart
      • sudo service mysql reload
      • sudo service mysql status
  • client
    • mysql -u root -proot
  • Enable remote access on root:

#comment out line: bind-address = 127.0.0.1 as following:
#bind-address = 127.0.0.1

sudo service mysql restart

mysql –u root -p
GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY 'root';
FLUSH PRIVILEGES;

how to use jenv

Configure which jvm to use

globally

vagrant@vagrant-ubuntu-vivid-64:~$ jenv global 1.8

locally (means which jvm to use in the current directory)

vagrant@vagrant-ubuntu-vivid-64:~$ jenv local 1.7

shell instance (which jvm to use in the current shell instance)

vagrant@vagrant-ubuntu-vivid-64:~$ jenv shell 1.7

precedence

1. shell
2. local
3. global

Configure jvm options

globally

vagrant@vagrant-ubuntu-vivid-64:~$ jenv global-options "-Xmx512m"

locally

vagrant@vagrant-ubuntu-vivid-64:~$ jenv local-options "-Xmx512m"

shell instance

vagrant@vagrant-ubuntu-vivid-64:~$ jenv shell-options "-Xmx512m"

precedence

same as for 'Configure which jvm to use'

Configure gc logging in shell scope

To set gc logging on do

vagrant@vagrant-ubuntu-vivid-64:~$ gc_set

and

vagrant@vagrant-ubuntu-vivid-64:~$ jenv info java

will output

Jenv will exec : /home/vagrant/.jenv/versions/1.8/bin/java -XX:+PrintGCDetails -Xloggc:gc.log
Exported variables :
  JAVA_HOME=/home/vagrant/.jenv/versions/1.8

To unset do

vagrant@vagrant-ubuntu-vivid-64:~$ gc_unset

Configure debug options

To set debug options on do

vagrant@vagrant-ubuntu-vivid-64:~$ jdebug_set

and

vagrant@vagrant-ubuntu-vivid-64:~$ jenv info java

will output

Jenv will exec : /home/vagrant/.jenv/versions/1.8/bin/java -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=8000,suspend=n
Exported variables :
  JAVA_HOME=/home/vagrant/.jenv/versions/1.8

To unset do

vagrant@vagrant-ubuntu-vivid-64:~$ jdebug_unset

Configure jrebel

Exported variables :
  JAVA_HOME=/home/vagrant/.jenv/versions/1.8

Configure jprofiler

To profile application with jprofiler (jprofiler agent.jar must to be placed in /home/vagrant/bin/jprofiler/bin/) do

vagrant@vagrant-ubuntu-vivid-64:~$ jprofiler_set

and

vagrant@vagrant-ubuntu-vivid-64:~$ jenv info java
