PHP APC缓存安装配置教程

作者：袖梨 2022-06-24

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

接下来按提示一步步完成即可

然后配置 /usr/local/php/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

下载apc

# wget http://pecl.php.net/get/APC-3.1.13.tgz
# tar -zxvf APC-3.1.13.tgz
# cd APC-3.1.13

生成configure文件

# /usr/local/php/bin/phpize

执行configure 并且make && make install

# ./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/php/lib/php/extensions/no-debug-non-zts-20100525/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

# vi /usr/local/php/etc/php.ini
extension_dir = "/usr/local/php/lib/php/extensions"
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

# service httpd restart

使用APC

test.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
