在JavaWeb開發中,JDK,Tomcat,Maven,Mysql等都是必不可少的。接下來我對在Linux上安裝JDK,Tomcat,Maven,Mysql等進行分享,使用環境:html
一、操做系統:CentOS 6.5 x64java
二、JDK:jdk-8u77-linux-x64linux
三、Tomcat:apache-tomcat-8.0.33sql
四、Maven:apache-maven-3.3.9apache
安裝:bootstrap
一、下載tomcat
Tomcat:下載地址oracle
JDK:下載地址maven
Maven:下載地址ui
二、解壓
1.tar zxvf jdk-8u77-linux-x64.tar.gz
2.tar zxvf apache-tomcat-8.0.33.tar.gz
3.tar zxvf apache-maven-3.3.9.tar.gz
三、安裝
1.mkdir /usr/local/java/
2.mv jdk-8u77-linux-x64/ /usr/local/java
3.mv apache-tomcat-8.0.33 /usr/local
4.mv apache-maven-3.3.9 /usr/local
四、配置環境變量
編輯/etc/profile,並在最下方添加一下內容
#java setting
JAVA_HOME=/usr/local/java/jdk-8u77-linux-x64
export JAVA_HOME
PATH=$JAVA_HOME/bin:$PATH
export PATH
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH
#tomcat setting
CATALINA_HOME=/usr/local/apache-tomcat-8.0.33
export CATALINA_HOME
#Maven setting
MAVEN_HOME=/usr/local/apache-maven-3.3.9
export PATH=$PATH:$MAVEN_HOME/bin
ok!
運行 source /etc/profile 使環境變量生效
五、驗證是否安裝成功
1.驗證JDK
java -version
將會看到以下信息:
java version "1.8.0_77"
Java(TM) SE Runtime Environment (build 1.8.0_77-b03)
Java HotSpot(TM) 64-Bit Server VM (build 25.77-b03, mixed mode)
2.驗證Tomcat
/usr/local/apache-tomcat-8.0.33/bin/startup.sh
將會看到以下啓動信息:
Using CATALINA_BASE: /usr/local/apache-tomcat-8.0.33
Using CATALINA_HOME: /usr/local/apache-tomcat-8.0.33
Using CATALINA_TMPDIR: /usr/local/apache-tomcat-8.0.33/temp
Using JRE_HOME: /usr/local/java/jdk1.8.0_77
Using CLASSPATH: /usr/local/apache-tomcat-8.0.33/bin/bootstrap.jar:/usr/local/apache-tomcat- 8.0.33/bin/tomcat-juli.jar
Tomcat started.
如今就能夠經過IP:8080訪問Tomcat。
注意:若是不能訪問請注意你的防火牆端口是否添加了8080端口。
1.#查看防火牆端口
2.service iptables
3.#查看Tomcat是否在進程中
4.ps -ef|grep tomcat
3.驗證Maven
mvn -version
將會看到以下信息:
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00)
Maven home: /usr/local/apache-maven-3.3.9
Java version: 1.8.0_77, vendor: Oracle Corporation
Java home: /usr/local/java/jdk1.8.0_77/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "2.6.32-431.23.3.el6.x86_64", arch: "amd64", family: "unix"
注意:若是提示mvn:permission denied
緣由是mvn這個文件沒有可執行權限,須要加上可執行權限
1.先cd到該文件的目錄下
2.執行命令chmod a+x ./mvn
而後再從新執行mvn -version看看
