【apache】Apache未启用mod_filter模块报错解决
如果未启用该模块，启动会报错如下：
Invalid command 'AddOutputFilterByType', perhaps misspelled or defined by a module not included in the server configuration
-AddOutputFilterByType has moved from the core to mod_filter, which must be loaded.
只需要在httpd.conf文件启用该模块即可：
LoadModule filter_module modules/mod_filter.so
