最简单的方法,找到php安装目录的pecl
自动安装:
# /usr/local/php/bin/pecl install apc
下面按提示一步步完成即可
配置/etc/php.ini 末尾加入 extension=apc.so
手动安装:
官网 http://cn2.php.net/manual/zh/book.apc.php
下载http://pecl.php.net/package/APC 找最新的
#wget http://pecl.php.net/get/APC-3.1.9.tgz
# tar -zxvf APC-3.1.9.tgz # cd APC-3.1.9 # /usr/local/php/bin/phpize (生产configure文件) # ./configure –enable-apc –enable-apc-mmap –with-php-config=/usr/local/php/bin/php-config # make # make install
拷贝添加SO文件 # cp /usr/local/lib/php/extensions/no-debug-zts-20060613/apc.so /usr/local/php/lib/php/extensions/apc.so # chmod 755 /usr/local/php/lib/php/extensions/apc.so 修改PHP.INI使之启动APC模块 修改 php.ini下 extension_dir = “./” extension_dir = “/usr/local/php/lib/php/extensions” 配置/etc/php.ini 末尾加入 extension=apc.so apc.enabled = 1 apc.cache_by_default = on apc.shm_segments = 1 apc.shm_size = 128 apc.ttl = 7200 apc.user_ttl = 7200 apc.num_files_hint = 1024 apc.write_lock = On apc.gc_ttl=3600 apc.ttl=0 apc.mmap_file_mask=/tmp/apc.XXXXXX 重启apache
#/usr/local/apache2/bin/apachectl restart
使用APC
<?php
print_r(apc_cache_info());
?>
注意 在浏览器看会不是很友好,可以查看网页源代码就看到很清晰

多次点击,可以发现num_hits在变化,说明缓存命中了!
压力测试看效果:
怎么压力测试看之前的文章 http://blog.csdn.net/21aspnet/article/details/6595984
先看看关闭apc功能,在php.ini中配置
# ab -n1000 -c10 http://localhost/tb.php
这个时候吞吐率Requests per second 比没用之前提高许多
