我正在运行 freepbx 版本 13，并开始升级到版本 14。系统是 CentOS 6 系统。系统首先需要进行某些升级，包括 php，我已将其升级到 5.6.40 并安装了 zenguardloader 2.6.0。我假设 php 和 zenguardloader 之间存在某种不兼容性，因为当我尝试运行 php 时出现以下情况。
[root@bluepukeko ~]# php -a
Failed loading /usr/lib64/php/modules/ZendGuardLoader.so: /usr/lib64/php/modules/ZendGuardLoader.so: undefined symbol: zend_get_hash_value
Interactive shell
php > echo "Zend engine version: " . zend_version();
Zend engine version: 2.6.0
php > quit
该系统还运行其他活动站点，因此我不能简单地擦除机器并重新启动，所以我需要找到解决问题的答案。
copy ZendGuard.ini

Copy opcache.ini

; The OPcache shared memory storage size.
opcache.memory_consumption=128
; The amount of memory for interned strings in Mbytes.

; The maximum percentage of "wasted" memory until a restart is scheduled.
;opcache.max_wasted_percentage=5
; When this directive is enabled, the OPcache appends the current working
; directory to the script key, thus eliminating possible collisions between
; files with the same name (basename). Disabling the directive improves
; performance, but may break existing applications.
;opcache.use_cwd=1
; When disabled, you must reset the OPcache manually or restart the
; webserver for changes to the filesystem to take effect.
;opcache.validate_timestamps=1
; How often (in seconds) to check file timestamps for changes to the shared
; memory storage allocation. ("1" means validate once per second, but only
; once per request. "0" means always validate)
;opcache.revalidate_freq=2
; Enables or disables file search in include_path optimization
;opcache.revalidate_path=0
; If disabled, all PHPDoc comments are dropped from the code to reduce the
; size of the optimized code.
;opcache.save_comments=1
; If disabled, PHPDoc comments are not loaded from SHM, so "Doc Comments"
; may be always stored (save_comments=1), but not loaded by applications
; that don't need them anyway.
;opcache.load_comments=1

; The location of the OPcache blacklist file (wildcards allowed).
; Each OPcache blacklist file is a text file that holds the names of files
; that should not be accelerated.
opcache.blacklist_filename=/etc/php.d/opcache*.blacklist
; Allows exclusion of large files from being cached. By default all files
; are cached.
;opcache.max_file_size=0
; Check the cache checksum each N requests.

; is not being accessed.
;opcache.force_restart_timeout=180
; OPcache error_log file name. Empty string assumes "stderr".
;opcache.error_log=
; All OPcache errors go to the Web server log.
; By default, only fatal errors (level 0) or errors (level 1) are logged.
; You can also enable warnings (level 2), info messages (level 3) or
; debug messages (level 4).
;opcache.log_verbosity_level=1
; Preferred Shared Memory back-end. Leave empty and let the system decide.
;opcache.preferred_memory_model=
; Protect the shared memory from unexpected writing during script execution.
; Useful for internal debugging only.

Piotr 经过多次咒骂和谩骂后，我基本上得出结论，我只是在浪费时间。虽然我可以让 Asterisk 和 FreePBX 在机器上运行其他功能，但当我尝试进行任何更新时，系统会慢慢地搞砸自己，清理混乱的努力根本不值得这么心痛。我最终放弃了，现在有一台运行虚拟化的专用机器，它为我提供了 10 台虚拟机，所有虚拟机都在愉快地一起玩。
