配置JDK

1. 卸载JDK

[xsdbc[@localhost](http://my.oschina.net/u/570656) ~]$ rpm -qa | grep openjdk | grep -v grep 
java-1.7.0-openjdk-1.7.0.75-2.5.4.2.el7_0.x86_64 
java-1.6.0-openjdk-devel-1.6.0.34-1.13.6.1.el7_0.x86_64 
java-1.7.0-openjdk-headless-1.7.0.75-2.5.4.2.el7_0.x86_64 
java-1.6.0-openjdk-1.6.0.34-1.13.6.1.el7_0.x86_64 
java-1.7.0-openjdk-devel-1.7.0.75-2.5.4.2.el7_0.x86_64

2. 依次卸载

rpm -e –nodeps java-1.7.0-openjdk-1.7.0.75-2.5.4.2.el7_0.x86_64 
rpm -e –nodeps java-1.6.0-openjdk-devel-1.6.0.34-1.13.6.1.el7_0.x86_64 
rpm -e –nodeps java-1.7.0-openjdk-headless-1.7.0.75-2.5.4.2.el7_0.x86_64 
rpm -e –nodeps java-1.6.0-openjdk-1.6.0.34-1.13.6.1.el7_0.x86_64 
rpm -e –nodeps java-1.7.0-openjdk-devel-1.7.0.75-2.5.4.2.el7_0.x86_64

3. 下载对应版本的JDK

http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html

4. 解压安装

[root@localhost java]# mkdir /usr/local/java
[root@localhost java]# tar -zxvf jdk-7u79-linux-x64.tar.gz

5. 设置环境变量

export JAVA_HOME=/usr/local/java/jdk1.7.0_79
export PATH=$PATH:/usr/local/java/jdk1.7.0_79/bin
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

使用source /etc/profile命令重新加载/etc/profile文件，使修改的内容在当前shell窗口中生效。（永久生效，重启系统或注销用户）

6. 测试

[root@localhost jdk1.7.0_79]# java -version
java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) Client VM (build 24.79-b02, mixed mode)

以上整个安装过程就OK了

但是整个过程太麻烦，可以通过shell脚本的方式快速实现.

7. 安装脚本

#!/bin/bash
# shell script to install jdk 

# 1\. remove openjdk if exists.

for i in $(rpm -qa | grep openjdk | grep -v grep)
do
  echo "Deleting rpm -> "$i
  rpm -e --nodeps $i
done

if [[ ! -z $(rpm -qa | grep jdk | grep -v grep) ]];
then 
  echo "-->Failed to remove the defult Jdk."
else 

# 2.tar and install JDK(jdk-7u75-linux-x64.tar.gz)

  tar -zxvf jdk-7u75-linux-x64.tar.gz
  mkdir /usr/java
  mv ./jdk1.7.0_75 /usr/java/jdk1.7.0_75
  rm -rf ./jdk1.7.0_75

# 3\. config /etc/profile

  echo "export JAVA_HOME=/usr/java/jdk1.7.0_75" >>/etc/profile
  echo -e 'export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar'>>/etc/profile
  echo -e 'export PATH=$PATH:$JAVA_HOME/bin'>>/etc/profile

  source /etc/profile  

fi

TOMCAT

1. 下载对应版本

2. 解压缩

[root@localhost tomcat]# tar -zxvf apache-tomcat-7.0.69.tar.gz

3. 开放端口

##开放8080
[root@localhost bin]# /sbin/iptables -I INPUT -p tcp --dport 8080 -j ACCEPT
##开放443
[root@localhost bin]# /sbin/iptables -I INPUT -p tcp --dport 443 -j ACCEPT
##保存配置
[root@localhost bin]# /etc/rc.d/init.d/iptables save
iptables: Saving firewall rules to /etc/sysconfig/iptables:[  OK  ]
##重启防火墙服务
[root@localhost bin]# service iptables restart
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Unloading modules:                               [  OK  ]
iptables: Applying firewall rules:                         [  OK  ]
##查看注册表状态
[root@localhost bin]# /etc/init.d/iptables status
Table: filter
Chain INPUT (policy ACCEPT)
num  target     prot opt source               destination         
1    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           tcp dpt:443 
2    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           tcp dpt:8080 
3    ACCEPT     all  --  0.0.0.0/0            0.0.0.0/0           state RELATED,ESTABLISHED 
4    ACCEPT     icmp --  0.0.0.0/0            0.0.0.0/0           
5    ACCEPT     all  --  0.0.0.0/0            0.0.0.0/0           
6    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           state NEW tcp dpt:22 
7    REJECT     all  --  0.0.0.0/0            0.0.0.0/0           reject-with icmp-host-prohibited 

Chain FORWARD (policy ACCEPT)
num  target     prot opt source               destination         
1    REJECT     all  --  0.0.0.0/0            0.0.0.0/0           reject-with icmp-host-prohibited 

Chain OUTPUT (policy ACCEPT)
num  target     prot opt source               destination

以上就可以远程访问了:
http://10.72.14.220:8080/

注册成服务

1.创建tomcat文件

#!/bin/bash
 #
 # kenny kenny.zhou@tom.com
 # /etc/rc.d/init.d/tomcat
 # init script for tomcat precesses
 #
 # processname: tomcat
 # description: tomcat is a j2se server
 # chkconfig: 2345 86 16
 # description: Start up the Tomcat servlet engine.

#java
export JAVA_HOME=/usr/local/java/jdk1.7.0_79
export PATH=$PATH:/usr/local/java/jdk1.7.0_79/bin
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

#tomcat
export CATALINA_HOME=/usr/local/tomcat/apache-tomcat-7.0.69/bin

if [ -f /etc/init.d/functions ]; then
 . /etc/init.d/functions
 elif [ -f /etc/rc.d/init.d/functions ]; then
 . /etc/rc.d/init.d/functions
 else
 echo -e "/atomcat: unable to locate functions lib. Cannot continue."
 exit -1
 fi

RETVAL=$?
 CATALINA_HOME="/usr/local/tomcat/apache-tomcat-7.0.69/"

case "$1" in
start)
 if [ -f $CATALINA_HOME/bin/startup.sh ];
 then
 echo $"Starting Tomcat"
 $CATALINA_HOME/bin/startup.sh
 fi
 ;;
 stop)
 if [ -f $CATALINA_HOME/bin/shutdown.sh ];
 then
 echo $"Stopping Tomcat"
 $CATALINA_HOME/bin/shutdown.sh
 fi
 ;;
 *)
 echo $"Usage: $0 {start|stop}"
 exit 1
 ;;
 esac

exit $RETVAL

2.将该文件移到/etc/init.d/文件夹下

3.授权

chmod -r 777 tomcat

4.服务stop或start，restart

[root@localhost init.d]# service tomcat stop
Stopping Tomcat
Using CATALINA_BASE:   /usr/local/tomcat/apache-tomcat-7.0.69/
Using CATALINA_HOME:   /usr/local/tomcat/apache-tomcat-7.0.69/
Using CATALINA_TMPDIR: /usr/local/tomcat/apache-tomcat-7.0.69//temp
Using JRE_HOME:        /usr/local/java/jdk1.7.0_79
Using CLASSPATH:       /usr/local/tomcat/apache-tomcat-7.0.69//bin/bootstrap.jar:/usr/local/tomcat/apache-tomcat-7.0.69//bin/tomcat-juli.jar
[root@localhost init.d]# service tomcat start

5.设置开机启动

chkconfig --add tomcat
