redis扩展

wget -c https://github.com/phpredis/phpredis/archive/php7.zip
unzip php7.zip
phpize
./configure --with-php-config=/usr/local/php/bin/php-config
/usr/local/php7/etc/php.ini中加入extension=redis.so

memchche.so

安装libevent.so出现的问题

configure: WARNING: You will need re2c 0.13.4 or later if you want to regenerate PHP parsers.

于是百度找解决方法

wget https://sourceforge.net/projects/re2c/files/0.16/re2c-0.16.tar.gz
tar zxf re2c-0.16.tar.gz && cd re2c-0.16
./configure
make && make install

error: Cannot find libevent headers

wget http://cloud.github.com/downloads/libevent/libevent/libevent-2.0.20-stable.tar.gz
tar zxvf libevent-2.0.20-stable.tar.gz
cd libevent-2.0.20-stable/
./configure --prefix=/usr/local/libevent-2.0.20-stable/
make
make install

 cd libevent-0.1.0
/usr/local/php/bin/phpize
 ./configure --with-php-config=/usr/local/php/bin/php-config --with-libevent=/usr/local/libevent-2.0.20-stable
 make && make install

安装多线程

pecl install phreads.so

extension="pthreads.so"
