解决编译apache出现的问题：configure: error: APR not found . Please read the documentation

1、编译apache时出错：

#./configure  --prefix=/usr/local/apache  --enable-so
checking for APR... no
configure: error: APR not found .  Please read the documentation

2、解决方法：

1.下载所需软件包：
    #wget http://archive.apache.org/dist/apr/apr-1.4.5.tar.gz  
    #wget http://archive.apache.org/dist/apr/apr-util-1.3.12.tar.gz  
    #wget http://jaist.dl.sourceforge.net/project/pcre/pcre/8.10/pcre-8.10.zip 
2.编译安装：
    #yum remove apr-util-devel apr apr-util-mysql apr-docs apr-devel apr-util apr-util-docs
    a:解决apr not found问题：
        # tar -zxf apr-1.4.5.tar.gz  
        # cd  apr-1.4.5  
        # ./configure --prefix=/usr/local/apr  
        # make && make install
    b:解决APR-util not found问题：
        # tar -zxf apr-util-1.3.12.tar.gz  
        # cd apr-util-1.3.12  
        # ./configure --prefix=/usr/local/apr-util -with- apr=/usr/local/apr/bin/apr-1-config  
        # make && make install
    c:解决pcre问题：
        #unzip -o pcre-8.10.zip  
        #cd pcre-8.10  
        #./configure --prefix=/usr/local/pcre  
        #make && make install 
3、最后编译Apache时加上：
        --with-apr=/usr/local/apr 
        --with-apr-util=/usr/local/apr-util
        --with-pcre=/usr/local/pcre
    例如：
        # ./configure --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --with-pcre=/usr/local/pcre --prefix=/usr/local/apache --enable-so
        编译完成。
