CentOS6.5安装jdk1.8和tomcat-7以及maven3.6

安装jdk

准备：只需要一个 jdk-8u11-linux-x64.tar.gz

操作如下

[root@vm1 ~]# ll
total 155316
-rw-------. 1 root root      1106 Jul  7 03:53 anaconda-ks.cfg
-rw-r--r--. 1 root root      8815 Jul  7 03:53 install.log
-rw-r--r--. 1 root root      3384 Jul  7 03:52 install.log.syslog
-rw-r--r--. 1 root root 159019376 Jul  7 06:00 jdk-8u11-linux-x64.tar.gz
[root@vm1 ~]# tar -zxf jdk-8u11-linux-x64.tar.gz
[root@vm1 ~]# ll

-rw-------. 1 root root      1106 Jul  7 03:53 anaconda-ks.cfg
-rw-r--r--. 1 root root      8815 Jul  7 03:53 install.log
-rw-r--r--. 1 root root      3384 Jul  7 03:52 install.log.syslog
drwxr-xr-x. 8 uucp  143      4096 Jun 16  2014 jdk1.8.0_11
-rw-r--r--. 1 root root 159019376 Jul  7 06:00 jdk-8u11-linux-x64.tar.gz
[root@vm1 ~]# mv jdk1.8.0_11/ /usr/local/
[root@vm1 ~]# cd /usr/local/
[root@vm1 local]# ls
bin  etc  games  include  jdk1.8.0_11  lib  lib64  libexec  sbin  share  src
[root@vm1 local]# cd
[root@vm1 ~]# ll
total 155316
-rw-------. 1 root root      1106 Jul  7 03:53 anaconda-ks.cfg
-rw-r--r--. 1 root root      8815 Jul  7 03:53 install.log
-rw-r--r--. 1 root root      3384 Jul  7 03:52 install.log.syslog
-rw-r--r--. 1 root root 159019376 Jul  7 06:00 jdk-8u11-linux-x64.tar.gz
[root@vm1 jdk1.8.0_11]# vi /etc/profile
	#文件末尾添加如下几行
	export JAVA_HOME=/usr/local/jdk1.8.0_11 #java的解压路径
	export CLASSPATH=.
	export JAVA_PATH=${JAVA_HOME}/bin
	export PATH=$PATH:${JAVA_PATH}
[root@vm1 jdk1.8.0_11]# source /etc/profile
[root@vm1 jdk1.8.0_11]# java -version #验证是否配置成功
java version "1.8.0_11"
Java(TM) SE Runtime Environment (build 1.8.0_11-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.11-b03, mixed mode)

如果出现java version的字眼说明安装成功，如果没有出现这些字眼，查看一下/etc/profile配置文件中对应的jdk路径是否正确，尤其是java的版本号，保存之后记得source一下

安装Tomcat

使用wget获取Tomcat的tar包进行直接解压

[root@vm1 ~]# wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-7/v7.0.94/bin/apache-tomcat-7.0.94.tar.gz

[root@vm1 ~]# tar -zxf apache-tomcat-7.0.94.tar.gz -C /usr/local/
[root@vm1 ~]# service iptables stop  #关闭防火墙

[root@vm1 ~]# service iptables status  #查看防火墙状态
iptables: Firewall is not running.

安装完成，在浏览器中输入IP:8080访问一下，如果出现一只三脚猫，说明安装成功

关闭防火墙的方法为：

	1. 永久性生效
		开启：chkconfig iptables on
		关闭：chkconfig iptables off

	2. 即时生效，重启后失效
		开启：service iptables start
		关闭：service iptables stop

开启某些端口的命令

[root@vm1 ~]# vi /etc/sysconfig/iptables #照葫芦画瓢就行了
	# Firewall configuration written by system-config-firewall
	# Manual customization of this file is not recommended.
	*filter
	:INPUT ACCEPT [0:0]
	:FORWARD ACCEPT [0:0]
	:OUTPUT ACCEPT [0:0]

安装maven

使用wget获取maven3.6.1的tar包进行安装

[root@vm1 ~]# wget http://mirror.bit.edu.cn/apache/maven/maven-3/3.6.1/binaries/apache-maven-3.6.1-bin.tar.gz
--2019-07-07 06:51:33--  http://mirror.bit.edu.cn/apache/maven/maven-3/3.6.1/binaries/apache-maven-3.6.1-bin.tar.gz
