PHP APC安装与使用
最簡(jiǎn)單的方法,找到php安裝目錄的pecl
自動(dòng)安裝:
#?/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
手動(dòng)安裝:
官網(wǎng)?http://cn2.php.net/manual/zh/book.apc.php
下載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 (生產(chǎn)configure文件)
# ./configure –enable-apc –enable-apc-mmap –with-php-config=/usr/local/php/bin/php-config
# make
# make install
拷貝添加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使之啟動(dòng)APC模塊
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
重啟apache
#/usr/local/apache2/bin/apachectl restart
使用APC
<?php
print_r(apc_cache_info());
?>
?
注意 在瀏覽器看會(huì)不是很友好,可以查看網(wǎng)頁(yè)源代碼就看到很清晰
Array
([num_slots] => 1031[ttl] => 0[num_hits] => 4[num_misses] => 1[num_inserts] => 1[expunges] => 0[start_time] => 1322818377[mem_size] => 4240[num_entries] => 1[file_upload_progress] => 1[memory_type] => mmap[locking_type] => spin Locks[cache_list] => Array([0] => Array([type] => file[device] => 2049[inode] => 883230[filename] => /var/www/tb.php[num_hits] => 4[mtime] => 1322818340[creation_time] => 1322818379[deletion_time] => 0[access_time] => 1322818482[ref_count] => 1[mem_size] => 4240))[deleted_list] => Array()[slot_distribution] => Array(

?多次點(diǎn)擊,可以發(fā)現(xiàn)num_hits在變化,說(shuō)明緩存命中了!

怎么壓力測(cè)試看之前的文章? http://blog.csdn.net/21aspnet/article/details/6595984
先看看關(guān)閉apc功能,在php.ini中配置
# ab -n1000 -c10 http://localhost/tb.php
這個(gè)時(shí)候吞吐率Requests per second 比沒(méi)用之前提高許多
