Httpd(apache)部署php日志报Invalid command 'php value'错误

随记：

当部署 php + httpd(Apahe) 环境的时候，如果出现错误 /var/www/html/.htaccess: Invalid command 'php_value', perhaps misspelled or defined by a module not included in the server configuration

原因在于 httpd mpm模式为非prefork模式，而且在.htacess文件中使用了php_value指令设置php环境参数，apache mpm mode有三种，具体性能差异可以百度谷歌

解决手段:

1. 不在.htaccess中使用php_value，使用其他指令或在php中设置相关参数
2. 修改apache的mpm模式
3. 谷歌

当前环境httpd mpm 模式可以通过命令httpd -V查询

默认为 event 模式

如果是通过dnf / yum之类的包管理工具安装的话，可以通过修改/etc/httpd/conf.modules.d/00-mpm.conf 文件修改mpm模式

[root@temp conf.modules.d]# cat 00-mpm.conf
# Select the MPM module which should be used by uncommenting exactly
# one of the following LoadModule lines.  See the httpd.conf(5) man
# page for more information on changing the MPM.

# prefork MPM: Implements a non-threaded, pre-forking web server
# See: http://httpd.apache.org/docs/2.4/mod/prefork.html
#
# NOTE: If enabling prefork, the httpd_graceful_shutdown SELinux
# boolean should be enabled, to allow graceful stop/shutdown.
#
LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

# worker MPM: Multi-Processing Module implementing a hybrid
# multi-threaded multi-process web server
# See: http://httpd.apache.org/docs/2.4/mod/worker.html

#LoadModule mpm_worker_module modules/mod_mpm_worker.so

# event MPM: A variant of the worker MPM with the goal of consuming

#LoadModule mpm_event_module modules/mod_mpm_event.so

注释掉mod_mpm_event.so，取消注释mod_mpm_prefork.so 重启apache即可
