十、cent OS开启APR模式报错：configure: error: Found APR 1.3.9. You need version 1.4.3 or newer installed

错误内容显示APR的版本过低，需要新版本

1. 到http://apr.apache.org/download.cgi#apr1这个地址下载所需要的包
   apr-1.4.5.tar.gz 
   apr-iconv-1.2.1.tar.gz 
   apr-util-1.3.12.tar.gz
2. 安装APR

   tar zxvf apr-1.4.5.tar
   cd apr-1.4.5
   ./configure --prefix=/usr/local/apr
   make
   make install  

3. 安装apr-iconv

   tar -zxvf apr-iconv-1.2.1.tar.gz
   cd apr-iconv-1.2.1
   ./configure --prefix=/usr/local/apr-iconv --with-apr=/usr/local/apr
   make
   make install

4. 安装 apr-util

   tar zxvf apr-util-1.3.12.tar.gz
   cd apr-util-1.3.12
   ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr --with-apr-iconv=/usr/local/apr-iconv/bin/apriconv
   make
   make install 

5. 在使用native的./configure命令时，要使用：./configure --with-apr=/usr/local/apr --with-java-home=/usr/local/java/jdk1.8.0_144 --with-ssl=/usr/local/openssl 用参数指定安装目录
