Apache2：無效命令“LockFile”

我的 Apache2 將無法工作，當我嘗試執行apache2 --version或任何其他 apache 命令時，它會出錯並顯示以下消息：

AH00526: Syntax error on line 89 of /etc/apache2/apache2.conf:
Invalid command 'LockFile', perhaps misspelled or defined by a module not included in the server configuration

我的/etc/apache2/apache2.conf（沒有無休止的評論）如下所示：

LockFile ${APACHE_LOCK_DIR}/accept.lock

閱讀httpd 2.4 升級文件。在幾項更改中，刪除了LockFile指令：

指令 AcceptMutex、LockFile、RewriteLock、SSLMutex、SSLStaplingMutex 和 WatchdogMutexPath 已替換為單個Mutex指令。您將需要評估在 2.2 配置中對這些已刪除指令的任何使用，以確定它們是否可以被刪除或需要使用 Mutex 替換。
