Introduction to Ansible

Posted by 4Aiur on 2014/01/31 in SysAdmin |

Introduction to Ansible


I don’t want input password every time when I run ansible, so prepare ssh key authentication agent for auto login.

# Generate ssh public private key pair
ssh-keygen -t rsa -b 4096 -f ~/.ssh/id_rsa
ssh-agent | head -2 > ~/.ssh/.agent.env
source ~/.ssh/.agent.env
ssh-add ~/.ssh/id_rsa

Install Ansible on a isolation environment.

mkdir ~/Ansible
cd  ~/Ansible  # or press Escape + .
sudo easy_install pip
pip install virtualenv
virtualenv .venv
source .venv/bin/activate
pip install ansible

Setup autoenv for load ansible environment automatically.

git clone git://github.com/kennethreitz/autoenv.git ~/.autoenv
echo "source ~/.autoenv/activate.sh" >> ~/.bash_profile
source ~/.autoenv/activate.sh
cat > ~/Ansible/.active_ansible <<\EOF
source ~/Ansible/.venv/bin/activate  # Activeate virtualenv
source ~/.ssh/.agent.env  # Load ssh-agent env
# or use private key file
# export ANSIBLE_PRIVATE_KEY_FILE=~/.ssh/id_rsa
export ANSIBLE_HOSTS=~/Ansible/inventory
export ANSIBLE_HOST_KEY_CHECKING=False  # Set ansible config
export ANSIBLE_FORKS=20  # Specify ansible parallel processes
echo "source ~/Ansible/.active_ansible" > .env

Usage examples

Inventory file

cat ~/Ansible/inventory


Run some ad-hoc commands

ansible web -m shell -a "uptime"

File Transfer

ansible web -m copy -a "src=foo dest=/tmp/foo"

Gathering Facts

ansible web -m setup


Distribute the public_key to remote hosts with playbook

cat > playbook.yaml <<EOF
- hosts: all
    authorized_keys: ~/.ssh/id_rsa.pub
    ssh_dir: /home/mlf4aiur/.ssh
    owner: mlf4aiur
    group: mlf4aiur
  - name: set attributes of .ssh
    action: file path={{ ssh_dir }} owner={{ owner }} group={{ group }} mode=0700 state=directory
  - name: put public key in ~/.ssh/
    action: copy src={{ authorized_keys }} dest={{ ssh_dir }}/authorized_keys owner={{ owner }} group={{ group }} mode=0600

ansible-playbook playbook.yaml -k -e "ssh_dir=/home/mlf4aiur/.ssh owner=mlf4aiur"

Write a customize playbook

Here is a Ansbile playbook example.

Playbook directory structure.

$ tree
|---example      # Role name
|-----files      # Statistic files
|-----tasks      # Put tasks here
|-----templates  # Template files
|-----vars       # Variabals

# roles/example/vars/main.yml
  authorized_keys: id_rsa.pub
  ssh_dir: /home/mlf4aiur/.ssh
  owner: mlf4aiur
  group: mlf4aiur

# roles/example/files/id_rsa.pub
# roles/example/tasks/main.yml
- name: set attributes of .ssh
  action: file path={{ ssh_dir }} owner={{ owner }} group={{ group }} mode=0700 state=directory
- name: put public key in ~/.ssh/
  action: copy src={{ authorized_keys }} dest={{ ssh_dir }}/authorized_keys owner={{ owner }} group={{ group }} mode=0600

Apply this playbook to distribute public_key.

# distribute_public_key.yml
- hosts: all
  gather_facts: False
    - example

ansible-playbook distribute_public_key.yml

Getting Started with Vagrant

Posted by 4Aiur on 2014/01/12 in SysAdmin |

Getting Started with Vagrant


Install VirtualBox or VMware first, and download the latest from Vagrant download page.

Launch a instance

cd ~/.vagrant.d/tmp/
wget http://developer.nrel.gov/downloads/vagrant-boxes/CentOS-6.4-x86_64-v20130731.box
vagrant box add CentOS-6.4-x86_64 CentOS-6.4-x86_64-v20130731.box
mkdir -p ~/.vagrant.d/init/myvm
cd ~/.vagrant.d/init/myvm
vagrant init CentOS-6.4-x86_64
vagrant up
vagrant ssh


# install rvm
\curl -sSL https://get.rvm.io | bash -s stable
source "$HOME/.rvm/scripts/rvm
gem install chef
mkdir -p ~/.vagrant.d/init/my-recipes/cookbooks
cd ~/.vagrant.d/init/my-recipes/cookbooks
for cookbook in yum mysql apache2
    knife cookbook site download $cookbook
# untar the cookbook tar file


config.vm.provision :chef_solo do |chef|
  chef.cookbooks_path = "../my-recipes/cookbooks"

  chef.add_recipe "yum"
  chef.add_recipe "yum::epel"
  chef.add_recipe "mysql"
  chef.add_recipe "apache2"

  # You may also specify custom JSON attributes:
    :mysql => {
      "server_root_password" => "yourmysqlpassword",
      "server_repl_password" => "yourmysqlpassword",
      "server_debian_password" => "yourmysqlpassword"
    :apache2 => {
      "listen_address" => ""

config.vm.provision :shell, :path => "provision.sh"


#!/usr/bin/env bash

sudo iptables -I INPUT -p tcp --dport 80 -j ACCEPT
sudo iptables -I INPUT -p tcp --dport 8080 -j ACCEPT
sudo yum -y update

Run a specific provisioner

vagrant provision --provision-with chef_solo

Run chef-solo on VM

sudo chef-solo -c /tmp/vagrant-chef-1/solo.rb -j /vagrant/chef_solo.json


  "mysql": {
    "server_root_password": "yourmysqlpassword",
    "server_repl_password": "yourmysqlpassword",
    "server_debian_password": "yourmysqlpassword"
  "apache2": {
    "listen_address": ""
  "run_list": [


Creating the Vagrantfile

Name the file Vagrantfile.pkg

Vagrant::Config.run do |config|
  # Forward apache
  config.vm.forward_port 80, 8080

Packaging the Project

$ vagrant package --vagrantfile Vagrantfile.pkg

Distributing the Box

$ vagrant box add my_box /path/to/the/package.box
$ vagrant init my_box
$ vagrant up


Enable debug:

VAGRANT_LOG=info vagrant up
set VAGRANT_LOG=info
vagrant up
VAGRANT_LOG=debug vagrant provision

Insecure world writable dir /Applications in PATH, mode 040777

Vagrant::Errors::VMBootBadState: The guest machine entered an invalid state while waiting for it
to boot. Valid states are 'starting, running'. The machine is in the
'poweroff' state. Please verify everything is configured
properly and try again.

If the provider you're using has a GUI that comes with it,
it is often helpful to open that and watch the machine, since the
GUI often has more helpful error messages than Vagrant can retrieve.
For example, if you're using VirtualBox, run <code>vagrant up</code> while the
VirtualBox GUI is open.

Run this to fix it:

sudo chmod 755 /Applications/

Mount error on v-root: /vagrant

When you start up your guest, you may get the following message unexpectedly:

[default] -- v-root: /vagrant
The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

mount -t vboxsf -o uid=<code>id -u vagrant</code>,gid=<code>id -g vagrant</code> v-root /vagrant

This is usually a result of the guest’s package manager upgrading the kernel without rebuilding the VirtualBox Guest Additions. To double-check that this is the issue, connect to the guest and issue the following command:

lsmod | grep vboxsf

If that command does not return any output, it means that the VirtualBox Guest Additions are not loaded. If the VirtualBox Guest Additions were previously installed on the machine, you will more than likely be able to rebuild them for the new kernel through the vboxadd initscript, like so:

sudo /etc/init.d/vboxadd setup

Upgrade VirtualBox Guest Additions https://gist.github.com/fernandoaleman/5083680

[default] The guest additions on this VM do not match the installed version of
VirtualBox! In most cases this is fine, but in rare cases it can
cause things such as shared folders to not work properly. If you see
shared folder errors, please update the guest additions within the
virtual machine and reload your VM.

Guest Additions Version: 4.2.8
VirtualBox Version: 4.3

Attach VBoxGuestAdditions.iso(can be found /Applications/VirtualBox.app/Contents/MacOS/VBoxGuestAdditions.iso) in VirtualBox manually.

For Ubuntu should run next commands:

sudo apt-get update -q
sudo apt-get install -q -y dkms
# Install linux-headers
sudo apt-get install -q -y linux-headers-3.2.0-23-generic
sudo mount -o loop,ro /dev/sr0 /mnt

For CentOS just need to run next command:

sudo mount -t iso9660 -o loop,ro /dev/cdrom /mnt/

Upgrade VirtualBox Guest Additions:

sudo sh /mnt/VBoxLinuxAdditions.run --nox11
vagrant reload

Fix Vagrant Box Hanging at Boot(grub menu)

Use VirtualBox to boot this VM, and run command: sudo update-grub

Daemon Skeleton introduction

Past couple of days, i’ve builded some daemon tools, tired to do the same thing again and again, i think i need a template, to create python project with daemon easy and fast. So created this template Daemon Skeleton.

In this template i used python-daemon as the daemonizer, and did some tweak, add SIGQUIT signal catching in this module, and reformat the source code according to PEP8.

Daemon Skeleton Quick start

Clone the git repository, remove folder .git, create isolated Python environment with virturalenv, install dependencies:

Then, done. You can continue your daemon project now.

Another things for build good Python project


  • Create your own requirements.txt, when you need

  • Upgrade the packages to latest version

  • create a new source distribution as tarball

  • Deploying your code automatically

  • Testing code

# Mac OS X tips

Find & Scan Wireless Networks from the Command Line in Mac OS X

sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport /usr/sbin/airport
airport -s

Reindexing Spotlight from the Command Line

Reindexing Spotlight from the command line is done with the mdutil tool, first launch Terminal and then type:

sudo mdutil -E /

This will reindex every mounted volume on the Mac, including hard drives, disk images, external drives, etc. Specific drives can be chosen by pointing to them in /Volumes/, to only rebuild the primary Macintosh HD:

sudo mdutil -E /Volumes/Macintosh\ HD/

To reindex an external drive named “External” the command would be:

sudo mdutil -E /Volumes/External/

Use of the mdutil command will spin up mds and mdworker processes as Spotlight goes to work.

Individually Reindexing Selected Files In rare cases, Spotlight can miss a file during index, so rather than reindex an entire drive you can also manually add an individual file to the search index with the mdimport command:

mdimport /path/to/file

The mdimport command can be used on directories as well.

Convert a DMG file to ISO

hdiutil convert /path/imagefile.dmg -format UDTO -o /path/convertedimage.iso

Convert an ISO file to DMG format

hdiutil convert /path/imagefile.iso -format UDRW -o /path/convertedimage.dmg

How to Remove Apps from Launchpad in Mac OS X

  1. Using Launchpad — Mac App Store apps only
    Hold down the Option key, and once the icons start jiggling click the “X” shown in the corner of icons that you want to delete. This removes the app from Launchpad, and does not uninstall them, but this is limited to apps installed from the Mac App Store. If you want to remove an app not installed through the Mac App Store, you have to use the method below:

  2. Using the Terminal — removes any application
    Launch the Terminal and enter the following command, replacing “APPNAME” with the name of the application you want to remove from Launchpad:

run command:

sqlite3 ~/Library/Application\ Support/Dock/*.db "DELETE from apps WHERE title='APPNAME';" && killall Dock

files system usage

sudo fs_usage -f filesys | grep -vE 'iTerm|X11|Xquartz|grep|syslogd'

Mac OS X 系统更新升级包下载后的存储位置,避免多台苹果电脑重复下载

打开 Finder,在顶部菜单栏点击 “前往”,在下拉菜单里选择 “前往文件夹…”,粘入下面这个路径,回车。
看到苹果电脑 Mac OS X 系统更新升级包了吧。

注意,上面这些操作的前提是:下载完系统升级包后别立刻安装,否则安装、重启后,Mac 会自动删除它们。

Stop Lion from Re-Opening Old Windows with Command+Option+Q

chflags nohidden ~/Library/

Access and Use Emoji in Mac OS X Lion

From almost any Mac OS X Lion app, select the “Edit” menu and pull down to “Special Characters”, or hit Command+Option+T

Turn web proxy on/off in Mac OS X Terminal

To turn the proxy off, use:

alias proxyon='networksetup -setwebproxystate Airport on; networksetup -setsecurewebproxystate Airport on'

title () { title=$1; echo -n -e "\033]0;$title\007" }

Convert a Text File to RTF, HTML, DOC, and more via Command Line

textutil -convert filetype filename
textutil -cat rtf file1.txt file2.txt file3.txt -output combinedFiles.rtf

Renewing a DHCP lease

sudo ipconfig set en0 DHCP
sudo ifconfig en0 down ; sudo ifconfig en0 up

Hold down the Power button and Home button simultaneously

When the screen flashes, a screenshot has taken


有如其他Unix,你可以在文件名前加上”.”来使其隐藏,例如 /.vol。

这在Finder中是有效的,不过在”ls -a”时却会显示出来。

Mac OS X使用根目录的 .hidden 文件管理需要在Finder中隐藏的文件列表。

同样,HFS+(Mac OS的文件系统)文件和目录可以有一个隐藏属性,通过SetFile命令来设置,SetFile -a V <filename>

你也可以关闭隐藏 属性,通过SetFile -a v <filename>



设置Network Preference中AirPort中的Automatic Proxy Configuration

选择proxy.pac后restart AirPort。


networksetup -setairportpower en1 off
networksetup -setairportpower en1 on

Twitter for Mac RT

defaults write com.twitter.twitter-mac QuoteTweetSyntax -string 'RT @{USERNAME}: {TEXT}'

Lock the Mac OS X Desktop

  1. shift+ctrl+reject
  2. via Menu Bar
    Launch “Keychain Access”, open Preferences, Select the checkbox next to “Show Status in Menu Bar”
  3. 另外一个方法就是设置Expose属性,在Active Screen Corners中找一个顺手的位置选择Put Display to Sleep,以后鼠标移动到那个角落就可以锁定屏幕了


我们精彩会发现菜单栏右上角有些图标是我们用不到的,那些可能是系统自带的,也可能是一些安装程序的默认设置, 按住command直接用鼠标把上面的图标从菜单栏拖下来即可。
