须有配置好的环境 详情见： centos6.5下yum安装lnmp(适合刚入职的新手的方法) http://www.cnblogs.com/qzjpkfj/p/4211126.html

具体安装步骤详情见：

转载自：Linux下安装php开发框架yaf    http://www.linuxde.net/2013/07/14805.html

1.下载并安装yaf扩展  http://pecl.php.net/package/yaf

    #wget http://pecl.php.net/get/yaf-2.2.9.tgz

#tar zxvf yaf-2.2.9.tgz

#cd yaf-2.2.9



[root@bogon yaf-2.2.9]# whereis phpize

phpize: /usr/bin/phpize /usr/share/man/man1/phpize.1.gz   (有可能 whereis phpize 运行的是空的，我配置就是；是因为phpize没安；一条命令安装：yum install php-devel)

/usr/bin/phpize



[root@bogon yaf-2.2.9]# /usr/bin/phpize

Configuring for:

PHP Api Version: 20090626

Zend Module Api No: 20090626

Zend Extension Api No: 220090626

#whereis php-config

php-config: /usr/bin/php-config /usr/share/man/man1/php-config.1.gz



#./configure --with-php-config=/usr/bin/php-config  （如果提示错误：configure: error: in `/root/yaf-2.2.9':configure: error: no acceptable C compiler found in $PATHSee `config.log' for more details. 说明没安装gcc  一条命令安装 yum -y install gcc）

#make && make install
    

    （make && make install 如果执行出错如下）
    

    

  

In file included from /root/yaf-2.1.2/yaf_router.c:28:

/usr/include/php/ext/pcre/php_pcre.h:29:18: error: pcre.h: No such file or directory

In file included from /root/yaf-2.1.2/yaf_router.c:28:

/usr/include/php/ext/pcre/php_pcre.h:45: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘*’ token

/usr/include/php/ext/pcre/php_pcre.h:46: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘*’ token

/usr/include/php/ext/pcre/php_pcre.h:52: error: expected specifier-qualifier-list before ‘pcre’

make: *** [yaf_router.lo] 错误 1

解决办法

# yum install pcre-devel  安装   pcre-devel 即可解决了。

2.添加扩展配置到 PHP .ini

在/etc/php.ini文件里添加一行

    extension=yaf.so
  

重启webserver　即可。

lnmp 下安装yaf
