--enable-mpms-shared=all--with-mpm=prefork|worker|event

2) Support for event MPM

3) asynchronous read/write support

4) support for each module and each directory using different log levels

5) Support Per-request (i.e. support <if>, <elseif>, and <Else> condition judgment)

6) Enhanced version of the expression parser;

7) Support millisecond keepalive timeout;

8) The FQDN (domain name) based virtual host no longer needs namevirtualhost;

9) Support users to use custom variables;

New modules: mod_proxy_fcgi, Mod_ratelimit, Mod_request, Mod_remoteip

Note: Version 2.4 Modifies some configuration mechanisms: no longer supports the use of order, allow, deny to implement IP-based access control;

(iv) Compile and install:
