php7 安装 yar 扩展

体验RPC框架Yar需要三步

1. 装二进制打包协议msgpack

2. 装yar拓展和依赖

    

1. 安装二进制打包协议msgpack

-----------------------------------------------------------------------------------------------

1. 安装PHP拓展包有很多种方式，当然没什么是比pecl更加来得暴力，用这个之前要确认phpize是否存在

find / -name phpize

2. 如果phpize不存在

yum install php-devel

3. Ok,先装msgpack

pecl install msgpack

安装跳了一大堆编译过程过程，省略ING 只关心后几行

Build process completed successfully
Installing '/usr/include/php/ext/msgpack/php_msgpack.h'
Installing '/usr/lib64/php/modules/msgpack.so'
install ok: channel://pecl.php.net/msgpack-0.5.6
configuration option "php_ini" is not set to php.ini location
You should add "extension=msgpack.so" to php.ini

安装完 msgpack.so 会自动复制到 php 扩展库，并写好配置。

2. 安装 yar

-----------------------------------------------------------------------------------------------

1. 下载 yar

wget http://pecl.php.net/get/yar-2.0.0.tgz

2. 解压编译

tar -zxvf yar-2.0.0.tgz
cd cd yar-2.0.0
/usr/bin/phpize
./configure --with-php-config=/usr/bin/php-config7.0*

遇到问题：

checking for cURL in default path... not found

configure: error: Please reinstall the libcurl distribution - easy.h should be in <curl-dir>/include/curl/

3. 安装 curl-devel

yum -y install curl-devel
sudo apt-get install libcurl4-gnutls-dev

ps：curl vs curl-deval

4. 安装 yar

make && make install

5. 复制 yar.so 到 php 扩展库下

sudo cp yar.so /usr/lib/php/20151012/yar.so

6. 扩展写配置文件

echo "extension=yar.so" > /etc/php/7.0/mods-available/yar.ini
ln -sf /etc/php/7.0/mods-available/yar.ini /etc/php/7.0/fpm/conf.d/20-yar.ini
ln -sf /etc/php/7.0/mods-available/yar.ini /etc/php/7.0/cli/conf.d/20-yar.ini

7. 重启 php-fpm nginx

service php7.0-fpm restart
service nginx restart

ps: php -ir 查询 phpinfo
