php – 启用APC会导致内部服务器错误

错误日志：

PHP Fatal error:  PHP Startup: apc_mmap: mkstemp on /tmp/apc.efdb4d failed: in Unknown on line 0
[Wed Jul 06 23:47:41 2011] [error] mod_fcgid: process /var/www/cgi-bin/cgi_wrapper/cgi_wrapper(22397) exit(communication error),get unexpected signal 11

我没有在我的php.ini文件中添加APC扩展,而是在/etc/php.d/中创建了一个apc.ini文件,这是我当前的APC配置

apc.ini配置：

; /etc/php.d/apc.ini

extension = apc.so

apc.enabled = 1
apc.shm_segments = 1
apc.shm_size = 128M
apc.optimization = 0
apc.num_files_hint = 4096
apc.ttl = 7200
apc.user_ttl = 7200
apc.gc_ttl = 0
apc.cache_by_default = 1
apc.filters = ""
apc.mmap_file_mask = "/tmp/apc.XXXXXX"
apc.slam_defense = 0
apc.file_update_protection = 2
apc.enable_cli = 0
apc.max_file_size = 10M
apc.stat = 1
apc.write_lock = 1
apc.report_autofilter = 0
apc.include_once_override = 0
;apc.rfc1867 = 0
;apc.rfc1867_prefix = "upload_"
;apc.rfc1867_name = "APC_UPLOAD_PROGRESS"
;apc.rfc1867_freq = 0
apc.localcache = 0
apc.localcache.size = 512
apc.coredump_unmap = 0
apc.stat_ctime = 0

即使在禁用APC后,我在尝试登录Plesk CP时遇到了另一个错误：

ERROR: Zend_Db_Statement_Exception
SQLSTATE[HY000]: General error: 1 Can't create/write to file '/tmp/#sql_6d7_0.MYI' (Errcode: 13)

我通过Plesk的Power Panel重新启动我的容器来解决上述问题.我认为必须将/ tmp更改为exec使用mount -o remount,exec / tmp通过pecl解决APC安装过程中的权限错误.安装完成后,我将/ tmp返回noexec.这些步骤的要点可以在here找到.

第一个错误仍未解决.

我目前正在运行：

> CentOS 5.6
> PHP 5.3.5
> FastCGI
>已安装APC 3.1.9

我不知道如何解决这个问题.是因为我使用最新版本的APC？还是apc.ini配置？在我启用apc扩展的位置是否重要？即/etc/php.ini与/etc/php.d/apc.ini

FastCGI和APC兼容性问题怎么样？

任何帮助或建议将不胜感激.
