Apache是使用非常广泛的web服务器，多平台支持，是时下最流行的Web服务器端软件之一。Apache快速、可靠，并且可通过简单的API扩充，就可以集成PHP/Python等语言解释器。文章这里讲解如何在linux下编译 Apache，以及如何编译Apache模块。
linux下编译Apache
下载Apache源代码，编译过程如下：
|
$ wget http://apache.fayea.com//httpd/httpd-2.4.12.tar.gz $ tar -zxf httpd-2.4.12.tar.gz $ cd httpd-2.4.12 $ ./configure --prefix=/usr/local/apache/ $ make && make install |
编译过程中，可能会出现了以下错误：
|
$ ./configure --prefix=/usr/local/apache/ checking for chosen layout... Apache checking for working mkdir -p... yes checking for grep that handles long lines and -e... /bin/grep checking for egrep... /bin/grep -E checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking target system type... x86_64-unknown-linux-gnu configure: configure: Configuring Apache Portable Runtime library... configure: checking for APR... no configure: error: APR not found. Please read the documentation. |
这里是因为Apache编译依赖 apr，没找到 apr 就无法正常安装。另外，Apache还依赖 apr-util 和 pcre
编译Apache依赖
APR是Apache可移植运行库，封装了所有操作系统调用，用来实现Apache内部组件对操作系统资源的使用，提高Apache的可移植性。APR和Apache分离出来，避免Apache开发过程中，还要针对不同的平台做不同处理。apr-util 相当于APR工具集。PCRE是实现正则的perl库。
编译和安装 APR
|
$ wget http://archive.apache.org/dist/apr/apr-1.5.2.tar.gz $ tar -zxf apr-1.5.2.tar.gz $ cd apr-1.5.2 $ ./configure --prefix=/usr/local/apr $ make && make install |
编译和安装 apr-util
|
$ wget http://archive.apache.org/dist/apr/apr-util-1.5.3.tar.gz $ tar -zxf apr-util-1.5.3.tar.gz $ cd apr-util-1.5.3 $ ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr $ make && make install |
编译和安装 pcre
|
$ wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.37.tar.gz $ tar -zxf pcre-8.37.tar.gz $ cd pcre-8.37 $ ./configure --prefix=/usr/local/pcre $ make && make install |
重新编译Apache
安装Apache依赖后，编译时加多几个参数，重新编译Apache
|
$ ./configure --prefix=/usr/local/apache/ \ --with-apr=/usr/local/apr \ --with-apr-util=/usr/local/apr-util \ --with-pcre=/usr/local/pcre $ make && make install |
编译Apache模块
这里以mod_concatx为例，说明如何编译Apache模块，步骤很简单。mod_concatx是apache模块，可以用来合并多个js/css，有效提高js/css加载速度
编译 mod_concatx 模块
|
$ wget http://apmod.googlecode.com/svn/trunk/mod_concatx/mod_concatx.c $ ln -s /usr/local/apache/bin/apxs /usr/local/bin/apxs $ apxs -c mod_concatx.c |
编译并安装mod_concatx 模块
|
$ apxs -iac mod_concatx.c |
这种编译方式会自动安装Apache模块，安装成功后，可以在Apache 模块目录找到 mod_concatx.so，并且 conf/httpd.conf 配置也会加上 mod_concatx 模块信息
启动Apache
|
$ /usr/local/apache/bin/httpd -k start |
注：Apache启动后，是以服务运行。如果想关闭Apache， 就使用以下命令：
|
$ /usr/local/apache/bin/httpd -k stop |
查看已加载的Apache模块
|
$ /usr/local/apache/bin/httpd -M Loaded Modules: core_module (static) so_module (static) http_module (static) mpm_event_module (static) authn_file_module (shared) authn_core_module (shared) authz_host_module (shared) authz_groupfile_module (shared) authz_user_module (shared) authz_core_module (shared) access_compat_module (shared) auth_basic_module (shared) reqtimeout_module (shared) filter_module (shared) mime_module (shared) log_config_module (shared) env_module (shared) headers_module (shared) setenvif_module (shared) version_module (shared) unixd_module (shared) status_module (shared) autoindex_module (shared) dir_module (shared) alias_module (shared) concatx_module (shared) |
说明mod_concatx已加载！
