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
