install virtual BOX, CentOS, Anaconda, iBash

iBash_setup.md

This article describes my steps to setup the iBash environment in my Windows 7 OS.

install virtual box

create a VM and install CentOS

• While installing, just select Linux, instead of Redhat
• Rember to select Desktop CentOS in one of the step, instead of using the default minimal CentOS, to use the GUI
• Install Enhance functions to the VM(Just click the menu item of the virtual box)
• Enable bi-directionaly Clipboard between VM and the Host OS.
• Specify a Share Folder to transfer to/from CentOS
• Restart CentOS, the share folder will be seen in the /media/sf_xxx. However, only root has the priviledge to access it. Normal user don't.

I tried the following way to make the normal user access the share folder, but failed. So, at last, I use the root user instead.

usermod -a -G vboxsf xuuuvhon
usermod -a -G root xuuuvhon
groups xuuuvhon
usermod -g root xuuuvhon
groups xuuuvhon
usermod -a -G xuuuvhon xuuuvhon

Install anaconda

• download anaconda, the integrated Python environment including IPython, it is a shell script.
• run the shell script bash Anaconda3-2.4.1-Linux-x86_64.sh
• The default install folder is /root/anaconda3
• I used the Python3.5 version of Anaconda.
• goto /root/anaconda3/bin to run ipython, python, idle
• ./ipython qtconsole to run ipython with GUI.
• ./spyder to run the IDE including Ipython and an editor(crash happens)
• `./ipython notebook' to run ipython with notebook

install bash_kernel for IPython

• there is a intro article here http://jeroenjanssens.com/2015/02/19/ibash-notebook.html
• https://github.com/takluyver/bash_kernel
• using pip to install
• Ipython is able to be used to create slides ipython nbconvert xxx.ipynb --to slides --post serve

[root@centostudy workspace]# pip install bash_kernel
Requirement already satisfied (use --upgrade to upgrade): bash-kernel in /root/anaconda3/lib/python3.5/site-packages
Requirement already satisfied (use --upgrade to upgrade): pexpect>=3.3 in /root/anaconda3/lib/python3.5/site-packages (from bash-kernel)

• run python -m bash_kernel.install -- after install, it can be used. Make sure the IPython and pip is under /root/anaconda3/bin instead of the system default

run 'ipython notebook' in a specified dir
menu->new->Bash

install texlive

• yum install texlive
• texlive is for convert .ipynb to pdf
• The command is like ipython nbconvert xxx.ipynb --to pdf
