mpm_prefork.conf 未加载/影响

我正在运行 apache2 服务器并且 mpm_prefork 已启用。

apache2.conf 确实包含：

Include mods-enabled/*.load
Include mods-enabled/*.conf

我的文件中有以下内容/etc/apache2/mods-enabled/mpm_prefork.conf：

<IfModule mpm_prefork_module>
        StartServers                     5
        MinSpareServers           5
        MaxSpareServers          10
        MaxRequestWorkers         150
        MaxConnectionsPerChild   0
</IfModule>

但当我这样做

sudo service apache2 stop
sudo service apache2 start
ps ax | grep apache2 | wc -l

它显示有 502 个 apache2 进程。这意味着它从某个地方获取了StartServers500 这个值。过去，我曾将 Start Servers 设置为 500 mpm_prefork.conf，但现在新的 conf 文件没有生效。

但是，如果我复制粘贴的内容mpm_prefork.conf并将其粘贴到末尾，apache2.conf则StartServers值会发生变化，我可以使用 看到它ps ax | grep apache2。显然有一些东西覆盖了文件mpm_prefork.conf，但我看不出原因。似乎没有任何东西apache2.conf被覆盖，我已将内容粘贴到这里：

# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>

好的，我之前也遇到过同样的问题。我查看了 mods-enabled 并找到了 mdm_prefork.conf 文件 - 其中包含服务器设置，不确定从哪里获取文件（它是一个链接）。在那里进行了更改 - 成功了。可能这是更好的方法，但对我来说有效。
