sonatype nexus3 install linux

First: download

Provide a download version

`wget https://download.sonatype.com/nexus/3/latest-unix.tar.gz`

Second: install

1. Check java environment

   • Requires jdk8, generally linux comes with open-jdk, I don't like it, if there are multiple jdk, you need to bin/nexusspecify jdk in the script

     INSTALL4J_JAVA_HOME_OVERRIDE=/opt/jdk8.12.2

   • jvm modify memory

     How to configure the memory is appropriate, please refer to the official documentation.
     ' Https://help.sonatype.com/repomanager3/installation/configuring-the-runtime-environment '

     Modify location:$install-dir/nexus-3.22.1-02/bin/nexus.vmoptions

       -Xms256m
       -Xmx256m
       -XX:MaxDirectMemorySize=2703m
       -XX:+UnlockDiagnosticVMOptions
       -XX:+LogVMOutput
       -XX:LogFile=../sonatype-work/nexus3/log/jvm.log
       -XX:-OmitStackTraceInFastThrow
       -Djava.net.preferIPv4Stack=true
       -Dkaraf.home=.
       -Dkaraf.base=.
       -Dkaraf.etc=etc/karaf
       -Djava.util.logging.config.file=etc/karaf/java.util.logging.properties
       -Dkaraf.data=../sonatype-work/nexus3
       -Dkaraf.log=../sonatype-work/nexus3/log
       -Djava.io.tmpdir=../sonatype-work/nexus3/tmp
       -Dkaraf.startLocalConsole=false
       -Djava.endorsed.dir=lib/endorsed
     

2. installation

   Here is the way to use the compressed package, just decompress it directly; you can also use docker, and then get it when you have time

   tar -zvxf ./nexus-3.22.1-02-unix.tar.gz

Third: run

1. port

   Default port: 8081

   Modify location: $install-dir/nexus-3.22.1-02/etc/nexus-default.properties

2. run

   Usually you can start successfully here, there may be errors, insufficient memory problems

   bin/nexus run

3. Run as a service

   • Create a nexus user

     adduser nexus
chown -R nexus:nexus $install-dir/nexus-3.22.1-02/
chown -R nexus:nexus $install-dir/sonatype-work/

   • Modify startup user

     Modify location:$install-dir/nexus-3.22.1-02/bin/nexus.rc

     content:run_as_user="nexus"

   • When /etc/systemd/system/creating the nexus.servicefile, write the following

     Attention to modify the path

       [Unit]
       Description=nexus service
       After=syslog.target network.target
         
       [Service]
       Type=forking
       LimitNOFILE=65536
       ExecStart=/opt/nexusDir/nexus-3.22.1-02/bin/nexus start
       ExecStop=/opt/nexusDir/nexus-3.22.1-02/bin/nexus stop
       User=nexus
       Group=nexus
       Restart=on-abort
         
       [Install]
       WantedBy=multi-user.target
     

   • Activate configuration and start

     Supplementary log file view:tail -f $install-dir/sonatype-work/nexus3/log/nexus.log

     When running as a service, the pid information is generally written in the / tmp / i4jdaemon_ * file.If the pid file is not written, the startup will fail and there is no log reminder.

     Modified location: $install-dir/nexus-3.22.1-02/bin/nexus.vmoptions
-Dinstall4j.pidDir=somefilepay attention to the file permissions of the nexus user

       #Reload systemctl
       sudo systemctl daemon-reload
     
       #激活该服务,回开机自动启动的,不想开机启动的话,systemctl disable nexus.service
       #补充:查看开机启动的服务 systemctl list-unit-files | grep enable
       sudo systemctl enable nexus.service
     
       sudo systemctl start nexus.service
     

4. access

   ip: port can be the
   default account amdin, the default password location:$install-dir/sonatype-work/nexus3/admin.password

Fourth: use

Relatively simple, roughly describe

1. Create your own view

   • Create a library file storage location Blob stores
   • Create a host library and choose a storage location
   • Create proxy library-Configurable Alibaba Cloud or other mirror warehouse
   • Create a group groupPublic-join host-proxy

2. Configure maven-setting file

    #访问私服用户和密码
    <server>
      <id>nexus</id>
      <username>admin</username>
      <password>*****</password>
    </server>
    #配置镜像-加入group
    <mirror>
      <id>nexus</id>
      <mirrorOf>*</mirrorOf>
      <name>Human Readable Name for this Mirror.</name>
      <url>http://localhost:8081/repository/groupPublic/</url>
    </mirror>
   

Fifth: supplement-upload third-party jar to nexus

Looking at the official documentation, I also stepped on a lot of pits. Here I provide two commands to import in batches. A single package can also be uploaded on the user interface; due to insufficient storage space on my linux server, the experiment of using jar to produce jar packages

1. method one:

    #类似于maven手动导包到本地仓库的命令
    # 注意:http://localhost:8081/service/rest/v1/components?repository=localItemOne-release
    #这个是别人的api,我们修改的地方就是自己的库名localItemOne-release
    curl -v -u admin:123456 -F "maven2.generate-pom=true" -F "maven2.groupId=com.talkweb.alipay" -F "maven2.artifactId=commons-codec" -F "maven2.packaging=jar" -F "version=1.6" -F "maven2.asset1=@E:/hytWork/code/jar/com.talkweb.alipay-commons-codec-1.6.jar;" -F "maven2.asset1.extension=jar" "http://localhost:8081/service/rest/v1/components?repository=localItemOne-release" 
   
    curl -v -u admin:123456 -F "maven2.generate-pom=true" -F "maven2.groupId=com.talkweb.alipay" -F "maven2.artifactId=jaxen" -F "maven2.packaging=jar" -F "version=1.1" -F "maven2.asset1=@E:/hytWork/code/jar/jaxen-1.1.jar;type=application/java-archive" -F "maven2.asset1.extension=jar" "http://localhost:8081/service/rest/v1/components?repository=localItemOne-release"
   

2. Method 2:

    #一pom的方式
    #注意:pom中只有maven的依赖信息,不要头尾,否则会解析失败
    #多个文件放一个pom中,总是只执行一个,试验多次,只好指定多个pom文件
    curl -v -u admin:123456 -F "maven2.generate-pom=false" -F "maven2.asset1=@E:/localService/pom.xml" -F "maven2.asset1.extension=pom" -F "maven2.asset2=@E:/hytWork/code/jar/core-3.0.0.jar;type=application/java-archive" -F "maven2.asset2.extension=jar" "http://localhost:8081/service/rest/v1/components?repository=localItemOne-release"
