Compiling and installing httpd2.4

httpd-2.4 requires a newer version of APR and Apr-util, so it needs to be upgraded beforehand. There are two ways to upgrade, one is to compile the installation through source code, and the other is to upgrade the RPM package directly.

Here you choose to use the source code to compile the way

1. Solve the dependency relationship

Yumgroupinstall-y "Development Tools" "Server platformdevelopment"

Yuminstall-y Pcre-devel

Download package

apr-1.5.0.tar.bz2

apr-util-1.5.3.tar.bz2

httpd-2.4.25.tar.bz2

(1) Compile and install Apr

Compiling the installation Apr

Unzip and enter the directory

./configure--PREFIX=/USR/LOCAL/APR

Make && make install

(2) Compile and install Apr-util

Unzip into the directory

./configure--prefix=/usr/local/apr-util--with-apr=/usr/lo CA L/APR need to specify Apr Path

(3) Compile and install httpd2.4

./configure--prefix=/usr/local/apache--sysconfdir=/etc/httpd24--enable-so--enable-ssl--enable-cgi-- Enable-rewrite--with-zlib--with-pcre--with-apr=/usr/local/apr--with-apr-util=/usr/local/apr-util-- Enable-modules=most--enable-mpms-shared=all--with-mpm=event

Make && make install

Add:

(1) Constructing MPM as static module

In all platforms, MPM can be built as a static module. Select a mpm at build time, linked to the server. If you want to change MPM, you must rebuild it. In order to use the specified MPM, use the parameter--with-mpm=name when executing the Configure script.

Name is the specified MPM name. After the compilation is complete, you can use./httpd-l to determine the selected MPM. This command lists all modules that are compiled into the server program, including MPM.

(2) Build MPM as dynamic module

In UNIX or similar platforms, MPM can be built as a dynamic module and loaded at run time as with other dynamic modules. Building MPM as a dynamic module allows you to change the MPM by modifying the contents of the LoadModule directive without rebuilding the server program.

Use the--enable-mpms-shared option to enable this feature when you execute a configure script. All MPM modules supported by this platform will be installed when the given parameter is all.

You can also give a list of modules in the parameters. The default MPM, which can be automatically selected or specified by the--WITH-MPM option when the Configure script is executed, then appears in the generated server configuration file. Edit the loadmodule instruction content to select a different mpm.

3. Modify the main configuration file of httpd and set the path of its PID file.

To edit the/etc/httpd/httpd.conf, add the following line:

Pidfile "/var/run/httpd.pid"

4, provide SYSV service script/etc/rc.d/init.d/httpd, the content is as follows:

#!/bin/bash

#

# httpd Startup script for the Apache httpserver

#

# Chkconfig:-85 15

# HTML files and CGI.

if [-F/ETC/SYSCONFIG/HTTPD]; Then

httpd_lang=${httpd_lang-"C"}

# This would preventinitlog from swallowing up a pass-phrase prompt if

# Mod_ssl needs apass-phrase from the user.

Exit 1

Esac

Exit $RETVAL

Then give execute permission for this script:

# chmod +X/ETC/RC.D/INIT.D/HTTPD

Join the Service list:

# chkconfig--add httpd

The next step is to start the service and test it.
