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:
$wgethttp://apache.fayea.com//httpd/httpd-2.4.12.tar.gz
$ tar -zxfhttpd-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.

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
$wgethttp://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
$wgethttp://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
$wgetftp://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
$ wgethttp://apmod.googlecode.com/svn/trunk/mod_concatx/mod_concatx.c
$ ln -s/usr/local/apache/bin/apxs /usr/local/bin/apxs
$ apxs -cmod_concatx.c
|
编译并安装mod_concatx 模块
$apxs -iacmod_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) 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!
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
