一、JDK配置

1、在centos 7的更新源中有JDK，使用yum即可下载安装

查看库中版本
[root@localhost ~]# yum search java|grep jdk
选择需要版本进行安装
[root@localhost ~]# yum install java-1.8.0-openjdk.x86_64 //安装目录是在: /usr/lib/jvm/java-1.8.0-openjdkXXX
设置环境变量
[root@localhost ~]# vi /etc/profile
    #set java environment  如果无效的话，加到  vim ~/.bash_profile
    JAVA_HOME=/usr/lib/jvm/java-1.8-openjdk //注意修改路径
    JRE_HOME=$JAVA_HOME/jre
    CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
    PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
    export JAVA_HOME JRE_HOME CLASS_PATH PATH

[root@localhost java]# source /etc/profile //使修改生效

二、安装tomcat

下载好apache-tomcat-7.0.69.tar.gz，xhell上传Centos 7

1、解压：

tar -zxvf  apache-tomcat-7.0.69.tar.gz  -C /usr/java/tomcat7

解压完整后删除安装包：

rm –f apache-tomcat-7.0.69.tar.gz

首先我们来配置一下tomcat的环境变量和内存设置，进入tomcat的bin目录后通过vi命令打开catalina.sh文件，并在其中加入如下配置：

JAVA_OPTS="-Xms512m -Xmx1024m -Xss1024K -XX:PermSize=512m -XX:MaxPermSize=1024m"
export JAVA_HOME=/usr/java/jdk/jdk1.7.0_80
export CATALINA_HOME=/usr/java/tomcat7/apache-tomcat-7.0.69
export CATALINA_BASE=/usr/java/tomcat7/apache-tomcat-7.0.69
export CATALINA_TMPDIR=/usr/java/tomcat7/apache-tomcat-7.0.69/temp

2、修改server.xml ，修改端口号，添加域名。阿里云默认只开放商用80端口

3、查验(服务器响应时间，有延迟，等会就好)

 [root@izuf64t2yduyjgxweag0f5z conf]# curl 127.0.0.1   //出现如下内容，表明外网地址对外发布。
