sonatype-nexus私服的搭建与settings的设置

一、sonatype-nexus私服的docker部署测试

 1.1、查找nexus镜像

docker search nexus

 1.2、宿主机上创建目录 /data/nexus3，并增加操作权限

# 创建目录
mkdir data && mkdir data/nexus3
# 添加修改权限
chmod 777 /data/nexus3/

 1.3、安装sonatype/nexus3，由于我测试用的虚拟机只有2G内存，所以设置容器的JVM内存为1G

# 1、下载镜像
docker pull sonatype/nexus3

# 2、启动容器
docker run -d -p 18081:8081 \
  --volume /data/nexus3:/nexus-data \
  --name nexus \
  -e INSTALL4J_ADD_VM_PARAMS="-Xms1g -Xmx1g -XX:MaxDirectMemorySize=1g"\
  sonatype/nexus3

1.4、nexus3容器启动OK，可以查看下状态

 二、设置maven的settings文件，加入私服镜像源，并配置release/snapshot版本相关的访问权限

 2.1、settings文件的设置示例

<?xml version="1.0" encoding="UTF-8"?>

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <!-- localRepository
   | The path to the local repository maven will use to store artifacts.
   |
   | Default: ${user.home}/.m2/repository
  <localRepository>/path/to/local/repo</localRepository>
  -->
  <!--
  <localRepository>/opt/apache-maven/repos</localRepository>
  -->
  <!--

   -->
  <pluginGroups>
    <!-- pluginGroup
     | Specifies a further group identifier to use for plugin lookup.
    <pluginGroup>com.your.plugins</pluginGroup>
    -->
  </pluginGroups>

  <!-- proxies
   | This is a list of proxies which can be used on this machine to connect to the network.
   | Unless otherwise specified (by system property or command-line switch), the first proxy
   | specification in this list marked as active will be used.
   |-->
  <proxies>
    <!-- proxy

     |

      <port>80</port>
      <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
    </proxy>
    -->
  </proxies>

  <!-- servers
   | This is a list of authentication profiles, keyed by the server-id used within the system.
   | Authentication profiles can be used whenever maven must make a connection to a remote server.
   |-->
  <servers>
    <server>

        <id>snapshots</id>

        <password>my@nexus123</password>
    </server>
  </servers>
  <mirrors>
    <mirror>
      <id>nexus</id>

                <url>http://192.168.1.108:18081/repository/maven-public/</url>

                <snapshots>
                    <enabled>true</enabled>
                </snapshots>
            </repository>
        </repositories>
        <pluginRepositories>
            <pluginRepository>
                <id>nexus</id>
                <url>http://192.168.1.108:18081/repository/maven-public/</url>
                <releases>

                    <enabled>true</enabled>
                </snapshots>
            </pluginRepository>
        </pluginRepositories>
    </profile>
  </profiles>
  <!-- activeProfiles
   | List of profiles that are active for all builds.
   |
  <activeProfiles>
    <activeProfile>alwaysActiveProfile</activeProfile>
    <activeProfile>anotherAlwaysActiveProfile</activeProfile>
  </activeProfiles>
  -->
   <activeProfiles>
       <activeProfile>nexus</activeProfile>
   </activeProfiles>
</settings>

 2.2、项目的POM文件设置release和snapshot的服务地址

<distributionManagement>
        <repository>
            <id>releases</id>
            <name>Nexus Release Repository</name>
            <url>http://192.168.1.108:18081/repository/maven-releases/</url>
        </repository>
        <snapshotRepository>
            <id>snapshots</id>
            <name>Nexus Snapshot Repository</name>
            <!--nexus3中该配置无效 true:推送的snapshot版本号会生成随机数保证唯一，false不产生随机数 -->
            <!-- <uniqueVersion>false</uniqueVersion> -->
            <url>http://192.168.1.108:18081/repository/maven-snapshots/</url>
        </snapshotRepository>
    </distributionManagement>

 2.3、执行maven的deploy命令，尝试推送snapshot镜像到私服
