Question

apc的编辑安装方式

------------------- apc ---------------------
pecl安装法
/alidata/server/php/bin/pecl install apc


########################
编译安装法


wget http://pecl.php.net/get/APC-3.1.9.tgz
tar zxvf APC-3.1.9.tgz
cd APC-3.1.9
/alidata/server/php/bin/phpize
./configure --enable-apc --enable-apc-mmap --with-php-config=/alidata/server/php/bin/php-config
make
make install


php配置文件加入以下内容：
extension=apc.so
[apc]
apc.enabled = 1
apc.shm_segments = 1
apc.shm_size = 30M
apc.optimization = 0
apc.num_files_hint = 0
apc.ttl = 0
apc.gc_ttl = 0
apc.cache_by_default = 1
apc.filters =
apc.mmap_file_mask = 
apc.slam_defense = 0
apc.file_update_protection = 2
apc.enable_cli = 0

extension = apc.so
[APC] 
apc.enabled = 1
apc.shm_segments = 1
apc.shm_size = 30M
apc.optimization = 0
apc.num_files_hint = 0
apc.ttl = 0
apc.gc_ttl = 0
apc.cache_by_default = 1
apc.filters =
apc.mmap_file_mask = 
apc.slam_defense = 0
apc.file_update_protection = 2
apc.enable_cli = 0


[Zend]
zend_extension_manager.optimizer=/alidata/server/Zend/lib/Optimizer-3.3.3
zend_extension_manager.optimizer_ts=/alidata/server/Zend/lib/Optimizer_TS-3.3.3
zend_optimizer.version=3.3.3
zend_extension=/alidata/server/Zend/lib/ZendExtensionManager.so
zend_extension_ts=/alidata/server/Zend/lib/ZendExtensionManager_TS.so

这是php.ini的部分。

Answer 1

apc与zend不兼容。xache比较合适。

Answer 2

是的。 决定弃用apc了，经谷歌调查发现apc和zend确实是个冤家，互补兼容。 使用eAccelerator正常。

Answer 3

哇，用的阿里的 服务器呀。。哈哈

Answer 4

关掉他们两个的任意一个都正常； 真不知道他们有什么仇恨

Answer 5

慢慢排错,先关掉apc,看看如何.

在关掉zend_optimizer.开启apc.

一步一步来.


Answer 6

抱歉，PHP我不会

Answer 7

@红薯  帮忙分析一下 该如何排查
