CentOS 7 系统环境
1. yum安装相关软件包gcc gcc++ zlib zlib-devel expat-devel
yum -y install gcc gcc++ zlib zlib-devel expat-devel
2. 安装apr

cd apr-util-1.6.1
./configure --prefix=/usr/local/apr-util -with-apr=/usr/local/apr/bin/apr-1-config
make
make install
cd ..
（自己设定安装目录，对应apr安装目录）
4. 安装apr-iconv
tar -zxvf apr-iconv-1.2.2.tar.gz
cd apr-iconv-1.2.2
./configure --prefix=/usr/local/apr-iconv --with-apr=/usr/local/apr

make
make install
（自己设定安装目录，对应apr、apr-util、pcre安装目录）
试下apache2.4能否启动：
/usr/local/apache24/bin/httpd -k restart
浏览器打开：http://localhost/
或者：curl 127.0.0.1
如显示“It works!”，证明apache2.4安装成功！
/usr/local/apache24/bin/httpd -k stop
cd /usr/local/apache24/logs
mkdir jklog
mkdir djwxlog
7. 安装mod_jk.so
