analyzes the HTTP headers included with the request, and passes them
on to the appropriate Host (virtual host).

二.下载安装JDK,yum安装后面依赖缺少时还要重新配置环境变量
（1）查看是否已安装jdk JDK1.8 验证
mx1f
rpm -qa | grep jdk
（2）查看jdk版本
java -version
（3）删除所有旧版本jdk
- 删除java的安装目录
#卸载所有openjdk相关文件输入
yum -y remove java-1.8.0-openjdk*
#卸载tzdata-java
yum -y remove tzdata-java.noarch
- vi /etc/profile 删除关于java的配置
- source /etc/profile 立刻生效; java -version 此时查不到
- 下载后解压 配置jdk 环境 在 /etc/ 下修改profile 将如下粘贴到最后
export JAVA_HOME=/usr/local/java/jdk8
export JRE_HOME=/usr/local/java/jdk8/jre
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOME/bin
