How to access the web server in VMWare Fusion on its host machine

Currently, I am in a team developing a web application that supports IEs. My development environment runs under Centos.

Some UI problems appear on IE but not other browsers. This situation leads me to be in need of reproducing those problems on my development environment to confirm if my issues are fixed. I tried to install IE on Centos using Wine, but it doesn’t work properly.

So, I think if I could access the web server on the virtual machine in its host?

Below steps are what I did to make it works.

1. Set the Virtual Machine’s Network Adapter to Bridged:

2. Get the IP V4 of the virtual machine using the below command in Terminal:

ifconfig
eth1 Link encap:Ethernet HWaddr 00:0C:29:11:C1:E8 
inet addr:192.168.0.178 Bcast:192.168.0.255 Mask:255.255.255.0
inet6 addr: fe80::20c:29ff:fe11:c1e8/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:536823 errors:0 dropped:0 overruns:0 frame:0
TX packets:241377 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000 
RX bytes:537011299 (512.1 MiB) TX bytes:27427710 (26.1 MiB)

Now you can browse your VM’s localhost outside of the virtual machine (your host machine) by replacing “localhost” by “192.168.0.178“.

How I setup my Terminal on Linux

Today, I got a new computer in my company. So I have to set it up to have my comfortability.

This one runs CentOS 7 and for Linux based OS, Terminal is what you work with the most.

So, I started to configure it.

  • Change the background color and cursor of Terminal

The default color of Terminal is white background and block cursor. But I prefer black background and underline cursor because white background is so dazzlingly bright.

So, open up the Terminal, choose from the menu: Edit > Profile Preferences:

2017-05-10_110243

2017-05-10_110512

  • Change Bash PS1 colors for easy navigating and observing and show git branch information

Bash allows us to customize color and appearance of Terminal information, below is my own style. For more information for your own customization, refer this link.

And I also work quite much with Git so I need to visible branch information in Terminal.

# get current branch in git repo
 function parse_git_branch() {
 BRANCH=`git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/'`
 if [ ! "${BRANCH}" == "" ]
 then
 STAT=`parse_git_dirty`
 echo "[${BRANCH}${STAT}]"
 else
 echo ""
 fi
 }

# get current status of git repo
 function parse_git_dirty {
 status=`git status 2>&1 | tee`
 dirty=`echo -n "${status}" 2> /dev/null | grep "modified:" &> /dev/null; echo "$?"`
 untracked=`echo -n "${status}" 2> /dev/null | grep "Untracked files" &> /dev/null; echo "$?"`
 ahead=`echo -n "${status}" 2> /dev/null | grep "Your branch is ahead of" &> /dev/null; echo "$?"`
 newfile=`echo -n "${status}" 2> /dev/null | grep "new file:" &> /dev/null; echo "$?"`
 renamed=`echo -n "${status}" 2> /dev/null | grep "renamed:" &> /dev/null; echo "$?"`
 deleted=`echo -n "${status}" 2> /dev/null | grep "deleted:" &> /dev/null; echo "$?"`
 bits=''
 if [ "${renamed}" == "0" ]; then
 bits=">${bits}"
 fi
 if [ "${ahead}" == "0" ]; then
 bits="*${bits}"
 fi
 if [ "${newfile}" == "0" ]; then
 bits="+${bits}"
 fi
 if [ "${untracked}" == "0" ]; then
 bits="?${bits}"
 fi
 if [ "${deleted}" == "0" ]; then
 bits="x${bits}"
 fi
 if [ "${dirty}" == "0" ]; then
 bits="!${bits}"
 fi
 if [ ! "${bits}" == "" ]; then
 echo " ${bits}"
 else
 echo ""
 fi
 }

export PS1="\[\e[31;40m\]\u\[\e[m\]@\[\e[33;40m\]\H\[\e[m\]:\[\e[36;40m\]\w\[\e[m\]\[\e[32m\]\`parse_git_branch\`\[\e[m\]\n"

Add above to .bashrc (sudo gedit ~/.bashrc and paste above scripts to the end of the file) file and the result:

2017-05-10_111541

P/s: don’t forget to run source ~/.bashrc to make it takes effects.

  • Setup git autocompletion

It supports us to work faster and more accurate with git commands. So to make it happens, I use a guide from here:

Get the autocompletion script:

curl https://raw.githubusercontent.com/git/git/master/contrib/completion/git-completion.bash -o ~/.git-completion.bash

Add the below script to the end of the ~/.bashrc file (sudo gedit ~/.bashrc):

test -f ~/.git-completion.bash && . $_

Fire up changes:

source ~/.bashrc

Now the Terminal is ready to be worked on. Yay.

Create a linux shell to wrap files to the corresponding wrapper folder

I have list of around 200 .log files, and I am in need of creating a wrapper for each file.
Laborious buffaloes may have a flow like: Copy file name > Right click and create a folder > Move the file into it, repeat 200 times. Seems ez.
And this case, beside those human-beings, linux shell is also a kind of that buffalo.
Ok let’s go.

What I have:

  • 20161208_access.log
  • 20161209_access.log

What I about to have:

  • 20161208_access\20161208_access.log
  • 20161209_access\20161209_access.log

Step 1:

[ducfilan@localhost]$ cd logs
[ducfilan@localhost logs]$ vi wrapper_creator
# wrapper_creator file.
for full_filename in *log; do # loop through the log files.
 filename="${full_filename%.*}" # get the file name without extension.
 mkdir -p "$filename" # create the folder.
 mv "$full_filename" "$filename" # move the file into it.
done
echo "Done!"

Ok done, save it.

Step 2:

In order to execute it, we need to grant the execute permission.

[ducfilan@localhost]$ chmod +x wrapper_creator

Step 3:

And execute it.

[ducfilan@localhost]$ ./wrapper_creator
Done!

Ok I have what I want.

How to auto compile sass/scss files in Eclipse

First of all, sass/scss compilation needs Ruby to work with.

So, ok, we will install it.

But, we need to use system wide Ruby, ’cause I tried with rvm but there comes some problems:

/usr/bin/env: ruby_executable_hooks: No such file or directory

So if you use rvm, switch it back to:

rvm use system

Now go to:

https://www.ruby-lang.org/en/documentation/installation/

Then to make sure that Ruby is successfully installed:

ruby -v

It should have some information like:

[ducfilan@localhost]$ ruby -v
 ruby 2.1.8p440 (2015-12-16 revision 53160) [x86_64-linux]

Now come to sass:

gem install sass
# su in case of permission errors

Once again to make sure:

sass -v

Some information like this means we’ve successfully installed it:

[ducfilan@localhost]$ sass -v
Sass 3.4.23 (Selective Steve)

Ok, preparation is done. Open your project in Eclipse.

Right click on it > Properties > Builder > New > Choose ‘Program’ then Ok.

2017-01-25_140725

We need to fill out some fields:

  1. Location
    • Get the location of sass using:
      • which sass
  1. Working Directory
    • Relative path to your folder, with ${workspace_loc:/…} as root. Use Browse workspace to make it ez.
  2. Arguments
    • --update ${workspace_loc:/QTEC-Web/public/sass}:${workspace_loc:/QTEC-Web/public/css} --sourcemap=none --style compressed
    • With:
      • –update: Means compiling when your sass file is changed.
      • ${workspace_loc:/QTEC-Web/public/sass}: Your sass folder
      • ${workspace_loc:/QTEC-Web/public/css}: Your output folder
      • –sourcemap=none: No generating .map file
      • –style compressed: Output style

For example in my case:

2017-01-25_141341.png

After that, don’t close the configuration screen.

Switch to Build options tab and check only following files, uncheck all others if they are pre-checked.

  1. Allocate Console
  2. During auto builds

Now you’re done, edit an .scss file and you will see the message of writing .css file in the output screen. If not, you’re doing it wrong.
