实验环境

系统：
    centos7
    工具：
    jdk-8u91-linux-x64.gz
    apache-maven-3.5.3-bin.tar.gz
    
    代码：
    因为不懂Java，源码github下载
    
    [root@maven ~]# cat /etc/redhat-release 
    CentOS Linux release 7.6.1810 (Core) 
    [root@maven ~]# ll
    total 185720
    -rw-------. 1 root root      1260 Oct 10 22:29 anaconda-ks.cfg
    -rw-r--r--. 1 root root   8799579 Oct 31 23:55 apache-maven-3.5.3-bin.tar.gz
    -rw-r--r--. 1 root root 181367942 Oct 31 23:55 jdk-8u91-linux-x64.tar.gz
    drwxr-xr-x. 5 root root        42 Nov  1 01:22 pipeline

一、配置java

1、解压到指定目录

[root@maven ~]# systemctl stop firewalld
    [root@maven ~]# tar -zxvf jdk-8u91-linux-x64.tar.gz  -C /usr/local/

2、配置环境变量

[root@maven ~]# vim /etc/profile

3、验证

[root@maven ~]# source  /etc/profile
    [root@maven ~]# java -version
    java version "1.8.0_91"
    Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
    Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)

二、配置maven

1、解压

[root@maven ~]# tar -zxvf apache-maven-3.5.3-bin.tar.gz  -C /usr/local/

2、修改maven源地址（默认的源为国外，下载速度非常慢，会导致mvn编译报错，修改成阿里源即可）

[root@maven ~]# vi  /usr/local/apache-maven-3.5.3/conf/settings.xml

3、添加maven到环境变量(可选)，如果不设置，使用mvn的时候直接输入绝对地址即可

[root@maven ~]# vim /etc/profile.d/maven.sh
    [root@maven ~]# source  /etc/profile
    [root@maven ~]# mvn -v
    Apache Maven 3.5.3 (3383c37e1f9e9b3bc3df5050c29c8aff9f295297; 2018-02-24T14:49:05-05:00)
    Maven home: /usr/local/apache-maven-3.5.3
    Java version: 1.8.0_91, vendor: Oracle Corporation
    Java home: /usr/local/jdk1.8.0_91/jre
    Default locale: en_US, platform encoding: UTF-8
    OS name: "linux", version: "3.10.0-957.el7.x86_64", arch: "amd64", family: "unix"

三、运行jar包并查看结果

（因为eureka依赖lib和pom，所以先mvn -f pom和lib，再执行mvn -f eureka，以上三个目录都包含pom.xml文件）

1、执行mvn -f pom

[root@maven ~]# cd pipeline/
    [root@maven pipeline]# ll
    total 0
    drwxr-xr-x. 3 root root 88 Nov  1 01:22 eureka
    drwxr-xr-x. 3 root root 70 Nov  1 01:22 lib
    drwxr-xr-x. 2 root root 39 Nov  1 01:22 pom
    [root@maven pipeline]# mvn -f pom clean install

过程：

成功

2、执行mvn -f lib

[root@maven pipeline]# mvn -f lib  clean install

3、执行mvn -f eureka

[root@maven pipeline]# mvn -f eureka  clean install

在 Building jar查看编译成功的jar包

4、运行jar包并查看结果

[root@maven target]# java -jar eureka-4.0-SNAPSHOT.jar

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RsYWRhZ2lv_size_16_color_FFFFFF_t_70 2][]

5、查看端口8761，使用浏览器访问

[root@maven ~]# ss -ntlp|grep java
    LISTEN     0      100         :::8761                    :::*                   users:(("java",pid=14803,fd=18))
