Centos7下按照配置nexus2

一、什么是Nexus

二、安装并配置Nexus

[root@linux-node1 ~]# http://www.sonatype.com/download-oss-sonatype
[root@linux-node1 ~]# tar -xf nexus-2.13.0-01-bundle.tar.gz
[root@linux-node1 ~]# cd nexus-2.13.0-01/bin
[root@linux-node1 ~]# mv nexus-2.13.0-01 /usr/local/
[root@linux-node1 ~]# cd /usr/local/
[root@linux-node1 local]# ls
apache-maven-3.3.9             bin  games    lib    libexec  nexus-2.13.0-01  sbin   src
apache-maven-3.3.9-bin.tar.gz  etc  include  lib64  maven    nodejs           share
[root@linux-node1 local]# ln -s nexus-2.13.0-01 nexus
[root@linux-node1 local]# cd /usr/local/nexus
[root@linux-node1 nexus]# ls
bin  conf  lib  LICENSE.txt  logs  nexus  NOTICE.txt  tmp
[root@linux-node1 nexus]# cp bin/nexus /etc/init.d/
[root@linux-node1 nexus]# chmod 755 /etc/init.d/nexus 
[root@linux-node1 nexus]# chown root /etc/init.d/nexus 、
[root@linux-node1 nexus]# vim /etc/init.d/nexus
NEXUS_HOME="/usr/local/nexus"
RUN_AS_USER=root
[root@linux-node1 init.d]# cd /etc/init.d/
[root@linux-node1 init.d]# chkconfig --add nexus
[root@linux-node1 init.d]# chkconfig --levels 345 nexus on
[root@linux-node1 init.d]# service nexus start

三、登录Nexus界面

登录界面：http://{ip}:8081/nexus/
默认用户名密码 admin admin123

四、Nexus的流程

Nexus MAVEN的私有仓库
如果没有nexus 项目的打包都需要通过公网下载
不利于包的管理和共用
如果没有私服，我们所需的所有构件都需要通过maven的中央仓库和第三方的Maven仓库下载到本地，而一个团队中的所有人都重复的从maven仓库下载构件

部署工作流：

五、Apache Maven

Apache Maven
To use Nexus Repository Manager Pro and Nexus Repository Manager OSS with Apache Maven, configure Maven to check the repository manager instead of the default, built-in connection to the Central Repository.

To do this, you add a mirror configuration and override the default configuration for the central repository in your ~/.m2/settings.xml as shown:

<settings>
  <mirrors>
    <mirror>
      <!--This sends everything else to /public -->
      <id>nexus</id>
      <mirrorOf>*</mirrorOf>
      <url>http://localhost:8081/nexus/content/groups/public</url>
    </mirror>
  </mirrors>
  <profiles>
    <profile>
      <id>nexus</id>
      <!--Enable snapshots for the built in central repo to direct -->
      <!--all requests to nexus via the mirror -->
      <repositories>
        <repository>
          <id>central</id>
          <url>http://central</url>
          <releases><enabled>true</enabled></releases>
          <snapshots><enabled>true</enabled></snapshots>
        </repository>
      </repositories>
     <pluginRepositories>
        <pluginRepository>
          <id>central</id>
          <url>http://central</url>
          <releases><enabled>true</enabled></releases>
          <snapshots><enabled>true</enabled></snapshots>
        </pluginRepository>
      </pluginRepositories>
    </profile>
  </profiles>
  <activeProfiles>
    <!--make the profile active all the time -->
    <activeProfile>nexus</activeProfile>
  </activeProfiles>
</settings>
