Maven仓库nexus

本地仓库

在setting.xml文件中，设置localRepository元素的值为你想连接的仓库地址即可

# cat /usr/local/maven/conf/settings.xml | grep localRepository
 < localRepository
  <!-- | The path to the local repository maven will use to store artifacts.
   |
   | Default: ${user.home}/.m2/repository
 -->
  <localRepository>/path/to/local/repo</localRepository>

远程仓库

需要解压maven-model-builder-3.6.1.jar文件

/usr/local/apache-maven-3.6.1/lib/maven-model-builder-3.6.1.jar

在win上解压后的目录里查看xml文件

maven-model-builder-3.6.1\org\apache\maven\model\pom-4.0.0.xml

超级pom的信息

<repositories>
    <repository>
      <id>central</id>
      <name>Central Repository</name>
      <url>https://repo.maven.apache.org/maven2</url>
      <layout>default</layout>
      <snapshots>
        <enabled>false</enabled>
      </snapshots>
    </repository>
  </repositories>

配置使用远程仓库

maven中配置jboss仓库

有两种方式，一种是在项目的pom.xml中<repositories>中添加,这是配置是针对具体的某一个项目,更多时候,我们想把jboss仓库作为所有项目的仓库,这就需要在maven的setting.xml中配置了.建议将maven/conf/setting.xml文件拷贝一份到你本地仓库的目录,作为用户配置文件。打开setting.xml文件,在里面添加一下内容：

  <profiles>  
    ...  
    <profile>  
      <id>jboss-public-repository</id>  
      <repositories>  
        <repository>  
          <id>jboss-public-repository-group</id>  
          <name>JBoss Public Maven Repository Group</name>  
          <url>https://repository.jboss.org/nexus/content/groups/public-jboss/</url>  
          <layout>default</layout>  
          <releases>  
            <enabled>true</enabled>  
            <updatePolicy>never</updatePolicy>  
          </releases>  
          <snapshots>  
            <enabled>true</enabled>  
            <updatePolicy>never</updatePolicy>  
          </snapshots>  
        </repository>  
      </repositories>
　　　 <!-- 插件仓库 -->
      <pluginRepositories>  
        <pluginRepository>  
          <id>jboss-public-repository-group</id>  
          <name>JBoss Public Maven Repository Group</name>  
           <url>https://repository.jboss.org/nexus/content/groups/public-jboss/</url>  
          <layout>default</layout>  
          <releases>  
            <enabled>true</enabled>  
            <updatePolicy>never</updatePolicy>  
          </releases>  
         <!-- 不下载快照版 -->
         <snapshots>  
            <enabled>false</enabled>  
            <updatePolicy>never</updatePolicy>  
          </snapshots>  
        </pluginRepository>  
      </pluginRepositories>  
    </profile>  
  </profiles>  
  <!-- 默认为激活状态-->
  <activeProfiles>  
    <activeProfile>jboss-public-repository</activeProfile>  
  </activeProfiles>  
  ...

如果想要停用JBoss仓库,可在setting.xml文件所在目录运行：mvn -Pjboss-public-repository install

添加插件组

<pluginGroups>
    ...
    <pluginGroup>org.jboss.maven.plugins</pluginGroup>
    ...
</pluginGroups>

Nexus介绍

下载nexus3.x
首先，从以下地址下载nexus：
http://www.sonatype.com/download-oss-sonatype
文档：
https://help.sonatype.com/repomanager3
选择下载nexus-3.16.2-01-unix.tar.gz，适用于所有平台，本文将在centos7.5系统下安装，操作系统信息如下：

注意nexus是基于Java开发的，所以要先安装JDK8及以上：jdk-8u211-linux-x64.rpm
cnetos7系列默认就安装了jdk

==删除原来的jdk包==
# rpm -qa | grep java //查询原有rpm包
# rpm --nodeps -e java-1.8.0-openjdk-headless-1.8.0.161-2.b14.el7.x86_64 java-1.8.0-openjdk-1.8.0.161-2.b14.el7.x86_64
 
//删除
# rpm -qa | grep java
//检查
# rpm -ivh jdk-8u211-linux-x64.rpm
# ls /usr/java/
default jdk1.8.0_211-amd64 latest
# ls /usr/java/ -l
总用量 0
lrwxrwxrwx 1 root root 16 1月 7 17:27 default -> /usr/java/latest #默认的jdk版本目录 default
drwxr-xr-x 8 root root 258 1月 7 17:27 jdk1.8.0_211-amd64
lrwxrwxrwx 1 root root 28 1月 7 17:27 latest -> /usr/java/jdk1.8.0_211-amd64
#
# echo $JAVA_HOME
 
# vim /etc/profile.d/java.sh
JAVA_HOME=/usr/java/latest
PATH=$PATH:$JAVA_HOME/bin
export JAVA_HOME PATH
# source /etc/profile
# java -version
java version "1.8.0_211"
Java(TM) SE Runtime Environment (build 1.8.0_211-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.211-b12, mixed mode)
 
然后 运行下面的youhua.sh命令
 
#/bin/bash
 
function ulimits(){
cat > /etc/security/limits.conf <<EOF
* soft noproc 20480
* hard noproc 20480

ulimit -n 65535

echo "[ulimits 配置] ==> OK"
}

echo "[内核 优化] ==> OK"
}
 
export -f ulimits
export -f kernel
 
ulimits

echo '[Success]System Init OK'
 
 
# sh +x youhua.sh
 
 
启动nexus服务
将安装包拷贝到linux操作系统路径下
解压
# tar zxvf nexus-3.16.2-01-unix.tar.gz
进入目录
# cd nexus-3.16.2-01/bin
 
 
设置systemd启动
 # cat /etc/systemd/system/nexus.service
[Unit]
Description=nexus service
After=network.target
 
[Service]
Type=forking
LimitNOFILE=65536
ExecStart=/data/nexus-3.16.2-01/bin/nexus start
#data/nexus-3.16.2-01 需要换成实际的目录
ExecStop=/data/nexus-3.16.2-01/bin/nexus stop
User=root
Restart=on-abort
 
[Install]
WantedBy=multi-user.target
 
设置环境变量export RUN_AS_USER=root，如下：
export RUN_AS_USER=root
或者
# cat /data/nexus-3.16.2-01/bin/nexus.rc
run_as_user=root
EG：尝试使用其他用户来启动，发现都失败了，反正私服就是在内网使用，使用root启动吧
 
# sudo systemctl daemon-reload   重新加载配置文件
# sudo systemctl start nexus.service  启动服务

这里提个醒，一定要注意java的版本，以及8081端口是否被占用等
