一、什么是Maven私服
私服是指公有服务器，是架设在局域网的一种非凡的近程仓库，目标是代理近程仓库及部署第三方构建。有了私服之后，当 Maven 须要下载构件时，间接申请私服，私服上存在则下载到本地仓库；否则，私服申请内部的近程仓库，将构件下载到私服，再提供给本地仓库下载
二、Maven装置
1.下载地址
http://maven.apache.org/download.cgi
2. 服务器装置jdk环境
肯定要依照Jdk而不是jre
yum install java-1.8.0-openjdk-devel.x86_64参考：https://www.cnblogs.com/yaun1498078591/p/10368884.html
3.装置Maven
3.装置Maven[root@localhost ~]# cd /data/tools/maven[root@localhost src]# wget https://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.8.1/binaries/apache-maven-3.8.1-bin.tar.gz[root@localhost src]# tar -zxvf apache-maven-3.8.1-bin.tar.gz4.配置零碎环境变量
[root@localhost jvm]# vim /etc/profileexport JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.292.b10-2.el8.x86_64export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jarexport PATH=$PATH:$JAVA_HOME/binexport MAVEN_HOME=/data/tools/maven/apache-maven-3.8.1export PATH=$PATH:$MAVEN_HOME/bin[root@localhost jvm]# source /etc/profile5.验证Maven是否装置胜利
执行命令:mvn -vApache Maven 3.8.1 (05c21c65bdfed0f71a2f2ada8b84da59348c4c5d)Maven home: /data/tools/maven/apache-maven-3.8.1Java version: 1.8.0_292, vendor: Red Hat, Inc., runtime: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.292.b10-2.el8.x86_64/jreDefault locale: en_US, platform encoding: UTF-8OS name: "linux", version: "4.18.0-301.1.el8.x86_64", arch: "amd64", family: "unix"三、装置Nexus
1.下载地址
https://www.sonatype.com/download-oss-sonatype
2. 源码装置
[root@localhost jvm]# cd /data/tools/maven/[root@localhost src]# wget https://sonatype-download.global.ssl.fastly.net/nexus/3/nexus-3.11.0-01-unix.tar.gz[root@localhost src]# tar -zxvf nexus-3.11.0-01-unix.tar.gz[root@localhost src]# mv nexus-3.11.0-01 /usr/local/nexus3. 启动nexus
默认端口8081，如果要批改端口能够在etc/nexus-default.properties配置中批改
启动：
[root@localhost src]# /data/tools/maven/nexus-3.11.0-01/bin/nexus startWARNING: ************************************************************WARNING: Detected execution as "root" user. This is NOT recommended! WARNING: ************************************************************ Starting nexus下面在启动过程中呈现正告：不举荐应用root用户启动，创个新用户就行。这个正告不影响nexus的失常拜访和应用。
4. 凋谢8081端口
[root@localhost src]# firewall-cmd --add-port=8081/tcp --permanentsuccess[root@localhost src]# firewall-cmd --reloadsuccess5. 浏览器拜访
这就把nexus服务搭建好了，默认管理员账号密码是admin/admin123

三、我的项目中配置应用
1.在开发代码电脑配置maven
本地写代码电脑的maven配置settings.xml 配置如下:
<servers> <server> <id>usr-releases</id> <username>admin</username> <password>admin123</password> </server> <server> <id>usr-snapshots</id> <username>admin</username> <password>admin123</password> </server> </servers> ......<profiles> <profile> <id>usr-private-repo</id> <repositories> <repository> <id>usr-releases</id> <url>http://192.168.0.80:9001/repository/maven-releases/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>false</enabled> </snapshots> </repository> <repository> <id>usr-snapshots</id> <url>http://192.168.0.80:9001/repository/maven-snapshots/</url> <releases> <enabled>false</enabled> </releases> <snapshots> <enabled>true</enabled> <updatePolicy>always</updatePolicy> </snapshots> </repository> </repositories> </profile></profiles> ......<activeProfiles> <activeProfile>usr-private-repo</activeProfile></activeProfiles>2.在我的项目的Pom文件配置distributionManagement，deploy时这样能力将打的jar包上传到私服
<distributionManagement> <!--pom.xml这里<id> 和 settings.xml 配置 <id> 对应 --> <repository> <id>usr-releases</id> <url>http://192.168.0.80:9001/repository/maven-releases/</url> </repository> <snapshotRepository> <id>usr-snapshots</id> <url>http://192.168.0.80:9001/repository/maven-snapshots/</url> </snapshotRepository></distributionManagement>
