Install Scala 2.10.x in Ubuntu
3. Install Scala2.11.83.1 in Ubuntu 16.04 LTS
Since I downloaded the tgz file in Windows, I need to upload it to Ubuntu. Here I use WinSCP (Same principle as FTP), First connect to Ubuntu:
Create the scala-evn folder under the home/user name/file, and drag the tgz file into it:
Enter the VM:
Ctrl + Alt + T open the console, go to the spark-evn folder, switch to the root mode, ls to list files (easy to copy), decompress:
$ tar –xzvf scala-2.11.8.tgz
Then change the permission:
$ sudo chmod -R 777 scala-2.11.8
View files:
Then, return to the root directory and configure the environment variable PATH:
cd ~vim .bash_profile
Add environment variables:
export SCALA_HOME=/home/wangchao/spark-evn/scala-2.11.8export PATH=$SCALA_HOME/bin:$PATH
After Esc, enter: wq to save and exit.
Then execute.. bash_profile (note that there is a space)
