应开发的要求，需要在服务器上为php安装apc模块

一、源代码安装：

wget http://pecl.php.net/get/APC-3.0.19.tgz
tar xzvf APC-3.0.19.tgz
cd APC-3.0.19

/usr/bin/phpize
./configure –enable-apc-mmap –enable-filehits –enable-apc
make
make install

二、yum 安装方法

yum install php-devel php-pear httpd-devel
pecl install apc

一路回车即可，最后会自动在/usr/lib64/php/modules下生成apc.so模块，配置php.ini加载即可。

如果有以下错误：

In file included from /usr/local/src/APC-3.1.5/apc.c:38:
/usr/include/php/ext/pcre/php_pcre.h:29:18: error: pcre.h: No such file or directory

make: *** [apc.lo] Error 1

安装 pcre-devel 就可以解决

yum install pcre-devel

G来的一些配置：

extension = apc.so
apc.enabled = 1
apc.optimization  = 0
apc.shm_segments = 1
apc.shm_size = 56
apc.ttl = 7200
apc.user_ttl  = 7200
apc.num_files_hint = 10000
apc.user_entries_hint = 10000
apc.mmap_file_mask = /tmp/apc.XXXXXX
apc.enable_cli = 1
apc.cache_by_default  = 1
apc.max_file_size = 5
apc.stat = 1
