keepalived iptables config (vrrp protocol)

Example:
# Allow keepalived

-I OUTPUT -o eth1 -d 224.0.0.0/8 -p vrrp -j ACCEPT

xampp: install & enable php_memcache on Window

1. Download the library that map with your PHP version. (Ex: 5.6.x)

Download here: http://windows.php.net/downloads/pecl/releases/memcache/3.0.8/
- XAMPP run in 32 bit. So, I choose this file: php_memcache-3.0.8-5.6-ts-vc11-x86.zip

2. Unzip and copy 2 files: php_memcache.dll & php_memcache.pdb into "ext" folder of php.
Ex: my folder is "F:\xampp\php\ext"

3. Restart apache on XAMPP

4. Test :
php -i | findstr "memcache"

Note:
- If you see this warning message: "PHP Warning: PHP Startup: memcache: Unable to initialize module".
Please check your PHP version, then try to download another "php_memcache" package.

xampp - php - install intl pecl extension on MAC (OSX)

Magento 2 (M2) require this extension of php for installation.
On window, just enable php_intl.dll but on MAC, it may be more difficult than i think :)

1. Check which php path
user$ which php

2. If you are using xampp on mac it should be
/Applications/XAMPP/xamppfiles/bin/php
but if its
/usr/bin/php
you need to change your OSx php

user$ PATH="/Applications/XAMPP/xamppfiles/bin:${PATH}"

user$ php -v

PHP 5.6.24 (cli) (built: Aug 26 2016 05:57:56)

user$ which php

/Applications/XAMPP/xamppfiles/bin/php

3. Install brew

user$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

4. Install icu4c
user$: brew install icu4c

5. Install autoconf

user$ brew install autoconf

6. Install Intl via PECL
user$ cd <your xampp path>/bin
user$ sudo ./pecl update-channels
user$ sudo ./pecl install intl

7. You can check if Intl was installed successfully
user$ cd <your xampp path>/bin
user$ ./php -m | grep intl

# it return 'intl'
