Apache是时下最流行的Webserver软件之中的一个,支持多平台,可高速搭建web服务,并且稳定可靠。并可通过简单的API扩充。就能够集成PHP/Python等语言解释器。
文章这里解说怎样在linux下编译 Apache,以及怎样编译Apache模块。
linux下编译Apache
下载Apache源码,编译步骤例如以下:
$ 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。可能会出现了下面错误:
$ ./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可移植执行库。封装了全部操作系统调用。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 |
又一次编译Apache
安装Apache依赖后,编译时加多几个參数,又一次编译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,说明怎样编译Apache模块,步骤非常easy。mod_concatx是apache模块,能够用来合并多个js/css。有效提高js/css载入速度
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 |
这样的编译方式会自己主动安装Apache模块,成功安装后,能够在Apache 模块文件夹找到 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,以后台服务执行。
假设想关闭Apache, 就使用下面命令:
$ /usr/local/apache/bin/httpd -k stop |
查看已载入的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已载入!
Apache无法正常执行的解决的方法
1. 80port被占用
$ netstat -anp | grep :80 |
找到占用port的Pid,kill掉就可以。
2. 防火墙默认禁用80port
$ 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,重新启动防火墙。
$ service iptables restart |
