选择自己需要的版本进行安装

yum install java-1.7.0-openjdk-devel.x86_64

配置环境变量

[root@localhost ~]# vi /etc/profile 在profile文件中添加如下内容

#set java environment 
JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.75.x86_64（java的安装路径）
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

验证及查看版本

java -version
echo $JAVA_HOME
echo $JRE_HOME
echo $CLASSPATH
echo $PATH

安装Tomcat7

下载tomcat7的安装文件

wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-7/v7.0.69/bin/apache-tomcat-7.0.69.tar.gz 解压并移到/usr/local目录下

tar -zxvf apache-tomcat-7.0.57.tar.gz
mv apache-tomcat-7.0.69/ /usr/local/tomcat

配置tomcat环境变量和内存设置

在tomcat的bin目录下打开catalina.sh文件，vi /usr/local/tomcat/bin/catalina.sh，添加以下信息：

JAVA_OPTS="-Xms512m -Xmx1024m -Xss1024K -XX:PermSize=512m -XX:MaxPermSize=1024m"
export TOMCAT_HOME=/usr/local/tomcat
export CATALINA_HOME=/usr/local/tomcat
export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.141-2.6.10.1.el7_3.x86_64
export JRE_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.141-2.6.10.1.el7_3.x86_64/jre

##### 启动、关闭Tomcat

启动/usr/local/tomcat/bin/startup.sh

Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.141-2.6.10.1.el7_3.x86_64/jre
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.

关闭/usr/local/tomcat/bin/shutdown.sh

手动部署web应用

方法一

在conf目录的server.xml中的，找到节点，添加如下标签：

<Context path="/hello" docBase="/root/helloworld" debug="0" privileged="true">
</Context>

方法二

在conf/Catalina/localhost目录下创建xml配置文件，文件容易如下：

<Context path="/hello" docBase="/root/helloworld" debug="0" privileged="true">
</Context>

此法有个优点，可以定义别名。服务器端运行的项目名称为path，外部访问的URL则使用XML的文件名。这个方法很方便的隐藏了项目的名称，对一些项目名称被固定不能更换，但外部访问时又想换个路径，非常有效。
