Apache源码编译安装
Apache是世界使用排名第一的Web服务器软件。它可以运行在几乎所有广泛使用的计算机平台上，由于其跨平台和安全性被广泛使用，是最流行的Web服务器端软件之一。它快速、可靠并且可通过简单的API扩充，将Perl/Python等解释器编译到服务器中。Apache 的安装无外乎两种方式：源代码安装和二进制包安装。这两种安装类型各有特色，二进制包安装不需要编译，而源代码安装则需要先配置编译再安装，二进制包安装在一个固定的位置下，选择固定的模块，而源代码安装则可以让你选择安装路径，选择你想要的模块。本文主要介绍源代码安装。系统环境：Red Hat Enterprise Linux 6.5 主要配置文件：httpd.conf获取源代码包 http://httpd.apache.org/ httpd-2.4.23.tar.bz2 http://apr.apache.org/apr-1.5.2.tar.gz apr-util-1.5.4.tar.gz安装之前需要将以上三个源代码包导入Linux系统内Apache服务源码安装开始root@localhost ~]#tar xzvf apr-1.5.2.tar.gz -C /opt/#tar xzvf apr-util-1.5.4.tar.gz -C /opt/
#tar xjvf httpd-2.4.23.tar.bz2 -C /opt/ //将源码包解压#cd /opt/ //切换到源码包解压目录
#cp -r apr-1.5.2/ httpd-2.4.23/srclib/apr
#cp -r apr-util-1.5.4/ httpd-2.4.23/srclib/apr-util //将apr源码注入httpd-2.4.23/srclib/apr目录中# mount /dev/cdrom /mnt/ //挂载光盘搭建yum仓库# vi /etc/yum.repos.d/rhel-source.repo //通过vi编辑器编辑yum仓库源

在文件最前面插入下面的行，使其支持chkconfig命令：
#!/bin/sh
# chkconfig: 2345 85 15

# chmod +x /etc/init.d/httpd
# chkconfig –add httpd //将httpd加入services管理器# vi /usr/local/apache/conf/httpd.conf //编辑Apache主配置文件只需修改下面这两行配置ServerNamelocalhost.localdomain //设置成hostname显示的名称
Listen 192.168.10.20：80 //192.168.10.20为服务器ip地址#service httpd start //启动服务查看httpd的80端口是否处于监听状态，如果没有处于监听状态，就是Linux防火墙的原因，可以清除防火墙规则重新启动服务即可# netstat -antp | grep httpd#service iptables stop#service httpd restart
我的操作系统是：
# cat /etc/issue
CentOS release 6.4 (Final)
我的安装过程：
编译apr
# vim configure 修改apr编译文件
将RM='$RM'替换成RM='$RM -f'
# CC="gcc -m64" CFLAGS="-march=native -O2 -pipe" ./configure --prefix=/usr/local/apr --enable-profile --enable-threads
编译apr-util
# yum install openldap-devel openssl-devel
# CC="gcc -m64" CFLAGS="-march=native -O2 -pipe" ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr--with-crypto --with-openssl=/usr/lib64 --with-ldap-include=/usr/lib64
编译pcre
# CC="gcc -m64" CFLAGS="-march=native -O2 -pipe" ./configure --prefix=/usr/local/pcre --enable-utf8 --enable-jit --enable-pcregrep-libz
编译httpd
# CC="gcc -m64" CFLAGS="-march=native -O2 -pipe" ./configure --prefix=/usr/local/apache2 --enable-load-all-modules --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --with-pcre=/usr/local/pcre --with-mpm=worker
编译安装后能正常启动，但是编译httpd的时候有警告：
# grep WARNING /usr/src/httpd-2.4.23/config.log
configure:10743: WARNING: apr/apr-util is compiled without ldap support
configure:18704: WARNING: apr/apr-util is compiled without ldap support
configure:29185: WARNING: nghttp2 version is too old
编译安装apr-util并无警告或错误：
# grep WARNING /usr/src/apr-util-1.5.4/config.log没有结果
http.conf配置里面没有加载ldap相关模块：
# grep ldap /usr/local/apache2/conf/httpd.conf 没有结果
求问：如何才能加载上ldap相关模块？
{:6_409:}
问题已解决：
apr-util编译时加载ldap模块方式应为--with-ldap --with-ldap-include=/usr/include/ --with-ldap-lib=/usr/lib64/
httpd编译安装完成后也加载了ldap相关模块，结果如下：
# grep ldap /usr/local/apache2/conf/httpd.conf
LoadModule authnz_ldap_module modules/mod_authnz_ldap.so
LoadModule ldap_module modules/mod_ldap.so
我安装的详细步骤如下，可以对比一下：
# wget http://apache.fayea.com//apr/apr-1.5.2.tar.gz http://apache.fayea.com//apr/apr-util-1.5.4.tar.gz https://sourceforge.net/projects/pcre/files/pcre/8.39/pcre-8.39.tar.gz http://apache.fayea.com/httpd/httpd-2.4.23.tar.gz
系统自带perl-5.10.1-141.el6_7.1.x86_64，高于版本5，满足要求
# yum install gcc gcc-c++ libtool make
config.layout 定义各种安装目录
config.nice 记录最后执行的./configure参数，升级软件包时需使用同样的参数
config.log 记录./configure执行的详细日志
安装步骤：
编译apr
# vim configure 修改apr编译文件
将RM='$RM'替换成RM='$RM -f'
注：修改一下，不然编译apr-util时一直重复出现libtool错误。
# CC="gcc -m64" CFLAGS="-march=native -O2 -pipe" ./configure --prefix=/usr/local/apr --enable-profile --enable-threads
注：--enable-profile --enable-threads 最好加上这两个参数，否则编译安装apr-util时会出现threads不支持错误
编译apr-util
# yum install openldap-devel openssl-devel
# CC="gcc -m64" CFLAGS="-march=native -O2 -pipe" ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr--with-crypto --with-openssl=/usr/lib64 --with-ldap --with-ldap-include=/usr/include/ --with-ldap-lib=/usr/lib64/
编译pcre
# CC="gcc -m64" CFLAGS="-march=native -O2 -pipe" CXX="g++ -m64" ./configure --prefix=/usr/local/pcre --enable-utf8 --enable-jit --enable-pcregrep-libz
注：
--enable-utf8 --enable-jit --enable-pcregrep-libz 这几个参数可以不接，个人习惯，对做实验没有他打影响
make install时警告：
libtool: warning: relinking 'libpcreposix.la'
libtool: warning: relinking 'libpcrecpp.la'
nginx不支持pcre2，这里不影响
编译httpd
# CC="gcc -m64" CFLAGS="-march=native -O2 -pipe" ./configure --prefix=/usr/local/apache2 --enable-load-all-modules --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --with-pcre=/usr/local/pcre --with-mpm=event
这种编译方式所加载的模块有：
# /usr/local/apache2/bin/apachectl -M
