2. Ubuntu 16.04 Configuration Development Environment (JDK Environment Configuration + scala Environment Configuration + Noejs Environment Configuration + Development Tool intellij IDEA + Data Analysis Python Environment + Development Tool Jupyter)

2.0. Configuration of environment variables at three levels of Ubuntu

2.0.1 temporary variable, that is, it will fail after exiting terminal.

export PATH=${PATH}

2.0.2 Single User Variable, equivalent to the "User Variable" of windows

vim ~/.bashrc

2.0.3 System Variables, equivalent to windows's "System Variables" - prompts never to modify environment variables!

vim /etc/environment

Tip: Ubuntu modifies the environment to fail to access the system

Press ctrl+alt+F1 to enter command prompt mode
Enter username and password

/usr/bin/sudo /usr/bin/vi /etc/environment

Change back

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"

Restart, you can

/usr/bin/sudo reboot

The global environment variable file under Tip:CentOS is: / etc/profile, and the single user environment variable file is: ~/. bash_profile.

JDK environment configuration (system environment variables)

Unzip and place / opt/ Java Under the road

cd /homw/wxl/Downloads
tar -zxf jdk-8u92-linux-x64.tar.gz
sudo mv jdk1.8.0_92 /opt/java

Configuring system variables

sudo vim /etc/profile.d/java.sh
#add to the content
export JAVA_HOME=/opt/java
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

The source variable takes effect under the current terminal

source /etc/profile

 
Or logout/user logout.
This allows user variables to take effect under the current user

2.2. Scala environment configuration

Unzip and move to / opt

cd /home/wxl/Downloads
tar -zxf scala-2.11.8.tgz

sudo mv scala-2.11.8 /opt/scala

scala environment variable configuration

sudo vim /etc/profile.d/scala.sh

#add to the content
export SCALA_HOME=/opt/scala
export PATH=${SCALA_HOME}/bin:$PATH

The source variable takes effect under the current terminal

source /etc/profile

View scala-version

2.3. Install Intellj IDEA

They only install one, otherwise the latter overrides the former, and if Python 2 and python 3 are required to use jupyter notebook together. Please look at 6.

2.7. Jupyter notebook supports both Python 2 and python 3.

If you're like me, because work requires both Python 2 and python 3 to work together, here's how to make two different versions of Python coexist.  
If you have installed jupyter notebook for Python 2, you want to be able to use the python 3 kernel at the same time when you open notebook.

python3 -m pip install ipykernel
python3 -m ipykernel install --user

If the jupyter notebook of Python 3 is installed in advance, replace the command part 3 with 2.
