Compiling and installing httpd-2.4

Installation of httpd-2.4

The experimental environment for centOS6.5, due to centOS6 on the library files and development tools such as not suitable for installing httpd-2.4, so need to manually install the two packages APR and apr-util,httpd-2.4 dependent on the 1.4 version of APR and Apr-util. Here's a brief introduction to Apr.

About APR

Apr (Apache portable runtime), Apache's Portable operating environment, Apache applications need to be developed according to different platforms due to the different underlying environments, and APR eliminates the difference between the underlying platforms, APR is capable of providing all APR feature support for most platforms, including Beos,unix,linux and so on, APR provides a common unified operation function interface for most of these platforms, so that the interfaces of Apache applications on different platforms are basically uniform and consistent.

Compiling the installation

1) Compile and install apr-1.5.0

[Email protected] ~]# tar xf apr-1.5.0.tar.bz2 [[email protected] ~]# CD Apr-1.5.0[[email protected] apr-1.5.0]#./config Ure--prefix=/usr/local/apr-1.5.0checking build system Type ... x86_64-unknown-linux-gnuchecking host system type ... x86 _64-unknown-linux-gnuchecking target system Type ... x86_64-unknown-linux-gnuconfiguring APR library ..... ..... [[email protected] apr-1.5.0]# make && make install

2) Compile and install apr-util-1.5.3

[[email protected] ~]# tar xf  apr-util-1.5.3.tar.bz2 [[email protected] ~]# cd apr-util-1.5.3[[email protected ] apr-util-1.5.3]# ./configure --prefix=/usr/local/apr-util-1.5.3/ --with-apr=/usr/local/ apr-1.5.0/checking build system type... x86_64-unknown-linux-gnuchecking host  system type... x86_64-unknown-linux-gnuchecking target system type... x86_64- unknown-linux-gnuchecking for a bsd-compatible install... /usr/bin/install - Cchecking for working mkdir -p... yes ........ [[Email protected] apr-util-1.5.3]# make && make install 

Since Apr-util relies on APR, it is necessary to specify the installed Apr by "--WITH-APR" when installing Apr-util.

2) Compile and install httpd-2.4.9

[Email protected] ~]# tar xf httpd-2.4.9.tar.bz2 [[email protected] ~]# CD Httpd-2.4.9[[email protected] httpd-2.4.9]#. /configure--prefix=/usr/local/apache2.4.9--sysconfdir=/etc/httpd--enable-so--enable-ssl--enable-cgi-- Enable-rewrite--with-zlib--with-pcre--with-apr=/usr/local/apr-1.5.0--with-apr-util=/usr/local/apr-util-1.5.3-- Enable-mpms-shared=all--with-mpm=event--enable-modules=most ...... [[email protected] httpd-2.4.9]# make && make install

A brief introduction to the various parameters involved:

--prefix=/usr/local/apache2.4.9 #应用程序安装路径

--SYSCONFDIR=/ETC/HTTPD #配置文件的安装路径

--enable-so #支持DSO动态装载模块

--enable-ssl #要编译启用ssl模块 (if you need to install Openssl-devel)

--enable-cgi #启用CGI模块 (enabled by default)

--enable-rewrite #URL重写 (the URL that the user accesses is automatically changed from the server to another URL, which is a very

#用的机制)

--with-zlib #这是一个压缩库 (dedicated for network transmission)

--with-pcre #使用增强的 Perl Regular Expression Analysis tool (use this to install Pcre-devel,pcre:

#正则表达式分析器)

--WITH-APR=/USR/LOCAL/APR #指明apr的目录 (if APR is in a special path)

--with-apr-util=/usr/local/apr-util/#指明apr-util Path (if apr-util under special path)

--enable-mpms-shared=all #把所有的mpm模块都编译进来而且是共享模块

--with-mpm=event #默认使用的mpm模块

--enable-modules=most|all #还有很多其他模块, the other dynamic loadable modules need to compile which

# (all: Compile, most: compile some common modules)

Add the Apache application Bin directory to the PATH environment variable. Because is the compilation installs, therefore does not have the corresponding script file in the/ETC/INIT.D directory, needs to write itself, does not write, directly the RPM package installs automatically generates the script file httpd to copy over, changes several of these parameters.

Modified the above parameters, where the compiled installation of the application will pidfile placed in /usr/local/apache2.4.9/logs/, you can modify the PID file placement by Pidfile parameters in the main configuration file.
