Its feature is that it can efficiently encapsulate the interfaces for external access. Its purpose is well, you know.

How can we use yar of great god in live broadcasting.

1. download.

Well, that's right. At the bottom of the article, laruence provided github.

However, this is not enough because the framework requiresMsgpackAgain, this is maintained by laruence !!

Ii. msgpack.

Well .....

It seems that the downloaded files are all. c. h files. That's right. We need to compile it ourselves!

1. msgpack

Decompress the package and check README. md.

## Install

### Install from PECL
Msgpack is an PECL extension, thus you can simply install it by:
"`
pecl install msgpack
"`
### Compile Msgpack from source
"`
$/path/to/phpize
$./configure 
$make && make install
"`

Well, we found that this can be installed online through pecl.

Open a terminal and enter

pecl install msgpack

Failed. The prompt is as follows:

Failed to download pecl/msgpack within preferred state "stable", latest release is version 0.5.5, stability "beta", use "channel://pecl.php.net/msgpack-0.5.5" to install
install failed

This is because msgpack does not have a stable version. Follow the instructions above to enter

pecl install  channel://pecl.php.net/msgpack-0.5.5

Still failed, but prompt changed

WARNING: configuration download directory "/build/buildd/php5-5.5.3+dfsg/pear-build-download" is not writeable.  Change download_dir config variable to a writeable dir to avoid this warningCannot install, php_dir for channel "pecl.php.net" is not writeable by the current user

It seems that we do not have the write permission for the folder. Next we switch to the root user and re-execute the above command

Too much content. Cut down the last section.

Build process completed successfully
Installing '/usr/lib/php5/20121212/msgpack.so'
Installing '/usr/include/php5/ext/msgpack/php_msgpack.h'
install ok: channel://pecl.php.net/msgpack-0.5.5
configuration option "php_ini" is not set to php.ini location
You should add "extension=msgpack.so" to php.ini

The following operation is to open the configuration file and write the extension to the file.

sudo gedit /etc/php5/apache2/php.ini

Restart apache

sudo /etc/init.d/apache2 restart

View phpinfo

So far, we have installed the PHP extension of msgpack.

Iii. Yar

Unzip the download yar-master.zip we still look at the README. md file, in fact, directly on github is also the same ....

The installation requirement requires the php extension to be installed. This is the importance of the previous step!

## Requirement
- PHP 5.2+
- Curl
- Json
- Msgpack (Optional)

Install yar

### Install Yar 
Yar is an PECL extension, thus you can simply install it by:
"
pecl install yar
"

It seems that we can also install it directly using the pecl command, which seems not so smooth.

Here we can see that we lack a re2c 0.13.4 or an updated version. In addition, our curl module does not meet the requirements and requires reinstallation.

Solve the problem below!

I found the re2c http://download.csdn.net/download/morre/5702707 in this address and skipped the re2c installation in the solution below, it seems that the above is just a warning, not too big a problem.

Let's go back to yar Compilation

Phpize is required for compilation, so we need to install phpize and install phpize.

yum install php-devel

The returned message is

The program "yum" has not been installed yet. Run the following command to install sudo apt-get install yum:

Well, install yum first, and install phpize. Note that when installing phpize, use RootUser execution!

Then reinstall the curl library and restart apache.

sudo apt-get install curl libcurl3 libcurl3-dev php5-curl

Sudo/etc/init. d/apache2 restart

Run the pecl installation command again.

Pecl install yar

Then there is no problem. After a short wait, the following prompt is displayed, and the installation is complete!

Build process completed successfully
Installing '/usr/lib/php5/20121212/yar.so'install ok: 
channel://pecl.php.net/yar-1.2.1configuration option "php_ini" is not set to php.ini locationYou should add "extension=yar.so" to php.ini

The following steps are the same as the previous one: modify the configuration file and restart apache.

sudo gedit /etc/php5/apache2/php.ini
sudo /etc/init.d/apache2 restart

After the restart, phpinfo does not see the corresponding extension.
