Linux Apache compile and install;

Apache is a common Web service-side tool, called HTTPd on Linux, and the service name is httpd;

On CentOS 6 default comes with httpd2.2 version, 7 on the default is 2.4 version;

2.4 HTTP Support uses the event model (each thread corresponds to a client request);

Before compiling the installation, you need to determine the APR, and Apr-util is already installed, you need to set the APR installation path when compiling and installing Apr-util--with-apr=/some/path

# MKDIR/SRC//Create a directory to store source packages;

To the Apache official website download httpd2.4 src source package httpd-2.4.25.tar.bz2;

--ENABLE-SO//Open dynamic loading module function;
