Apache是时下最流行的Web服务器软件之一,支持多平台,可快速搭建web服务,而且稳定可靠,并可通过简单的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 --no-check-certificat https://raw.githubusercontent.com/chenweiqi/apmod/master/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,以后台服务运行。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)

 mpm_event_module (static)

 version_module (shared)
 unixd_module (shared)
 status_module (shared)

说明mod_concatx已加载!

Apache无法正常运行的解决办法

1. 80端口被占用

netstat -anp | grep :80

找到占用端口的Pid,kill掉即可。

2. 防火墙默认禁用80端口

vi /etc/sysconfig/iptables

加多一行记录
-A RH-Firewall-1-INPUT -p tcp -m state –state NEW -m tcp –dport 80 -j ACCEPT
保存后,重启防火墙。

service iptables restart
