近期在玩apache，首先安装apace要配置apr。apr-util，pcre，而配置这些基本都是千篇一律。所谓程序猿的精神就是降低反复性的劳动，以下请看我写的apache安装脚本：

 

#!/bin/bash
# 须要sudo运行

dir=`pwd`

#要安装pcre先要安装 g++
if [[ `ls /etc|grep redhat-release` != "" ]]
then
    yum -y install gcc gcc-c++
elif [[ `ls /etc|grep debian_version` != "" ]]
then
    apt-get -y install gcc gcc-c++
fi

if [[ `ls|grep apr` == "" ]]
then
    wget http://mirrors.cnnic.cn/apache//apr/apr-1.5.2.tar.gz
fi
tar -zxvf apr-1.5.2.tar.gz
mkdir /usr/local/lib/apr-1.5.2
cd $dir/apr-1.5.2
./configure --prefix=/usr/local/lib/apr-1.5.2 
make
make install

cd $dir
if [[ `ls|grep apr-util` == "" ]]
then
    wget http://mirrors.cnnic.cn/apache//apr/apr-util-1.5.4.tar.gz
fi
tar -zxvf apr-util-1.5.4.tar.gz
mkdir /usr/local/lib/apr-util-1.5.4.tar.gz
cd $dir/apr-util-1.5.4
./configure --prefix=/usr/local/lib/apr-util-1.5.4 --with-apr=/usr/local/lib/apr-1.5.2
make 
make install

cd $dir
if [[ `ls|grep pcre` == "" ]]
then
    wget http://ncu.dl.sourceforge.net/project/pcre/pcre/8.37/pcre-8.37.tar.gz
fi
tar -zxvf pcre-8.37.tar.gz
mkdir /usr/local/lib/pcre-8.37
cd $dir/pcre-8.37
./configure --prefix=/usr/local/lib/pcre-8.37
make 
make install

cd $dir
if [[ `ls|grep httpd` == "" ]]
then
    wget http://www.apache.org/dist/httpd/httpd-2.4.12.tar.gz
fi
tar -zxvf httpd-2.4.12.tar.gz
mkdir /usr/local/lib/httpd-2.4.12
cd $dir/httpd-2.4.12
./configure --prefix=/usr/local/lib/httpd-2.4.12 --with-apr=/usr/local/lib/apr-1.5.2  --with-apr-util=/usr/local/lib/apr-util-1.5.4 --with-pcre=/usr/local/lib/pcre-8.37  --enable-so
make
make install
