nexus3安装与使用

一、nexus3安装包安装

1.下载

nexus2下载地址: https://help.sonatype.com/repomanager2/download

2.安装与运行

可以参考 https://help.sonatype.com/repomanager3/installation 即可

• 需要的环境

1. 必须jdk1.8以上
2. 设置环境变量，INSTALL4J_JAVA_HOME_OVERRIDE=/usr/lib/jvm/java-8-oracle

   参考 https://help.sonatype.com/repomanager3/installation/java-runtime-environment

• 运行启动

  windows下使用nexus.exe /run，注意前面有/

  To start the repository manager from application directory in the bin folder on a Unix-like platform like Linux use:

    ./nexus run
  

  The equivalent invocation on Windows requires a / in front of the run and any other commands.

    nexus.exe /run
  

  start, stop, restart, force-reload and status commands. The Windows nexus.exe command supports similar commands with a prefix of / e.g., /start

3.Windows安装

（1）下载好nexus安装包，并解压到指定（任意）目录

（2）启动nexus

nexus.exe /run

（3）访问

启动成功后访问 http://localhost:8081

至此安装成功

可以使用默认的用户名密码登录管理nexus

用户名 admin

密码 admin23

二、docker安装nexus3

1.下载镜像并运行docker容器

$ mkdir /some/dir/nexus-data && chown -R 200 /some/dir/nexus-data
$ docker run -d -p 8081:8081 --name nexus -v /some/dir/nexus-data:/nexus-data sonatype/nexus3

-d 后台运行
–name docker容器名
-v 挂载宿主机目录/some/dir/nexus-data为docker中/nexus-data目录持久数据保存地址
容器名称 sonatype/nexus3

执行上面的命令后：

[root@docker136 ~]# mkdir -p /some/dir/nexus-data && chown -R 200 /some/dir/nexus-data
[root@docker136 ~]# docker run -d -p 8081:8081 --name nexus -v /some/dir/nexus-data:/nexus-data sonatype/nexus3

2.访问

访问 192.168.72.136:8081即可得到nexus欢迎页

3.官方参考

安装官方参考地址
https://hub.docker.com/r/sonatype/nexus3/

Running
To run, binding the exposed port 8081 to the host.

$ docker run -d -p 8081:8081 --name nexus sonatype/nexus3

To test:

$ curl -u admin:admin123 http://localhost:8081/service/metrics/ping

Notes
Default credentials are: admin / admin123

It can take some time (2-3 minutes) for the service to launch in a new container. You can tail the log to determine once Nexus is ready:

$ docker logs -f nexus

Installation of Nexus is to /opt/sonatype/nexus.

A persistent directory, /nexus-data, is used for configuration, logs, and storage. This directory needs to be writable by the Nexus process, which runs as UID 200.

There is an environment variable that is being used to pass JVM arguments to the startup script

INSTALL4J_ADD_VM_PARAMS, passed to the Install4J startup script. Defaults to -Xms1200m -Xmx1200m -XX:MaxDirectMemorySize=2g -Djava.util.prefs.userRoot=${NEXUS_DATA}/javaprefs.
This can be adjusted at runtime:

$ docker run -d -p 8081:8081 --name nexus -e INSTALL4J_ADD_VM_PARAMS="-Xms2g -Xmx2g -XX:MaxDirectMemorySize=3g  -Djava.util.prefs.userRoot=/some-other-dir" sonatype/nexus3

Of particular note, -Djava.util.prefs.userRoot=/some-other-dir can be set to a persistent path, which will maintain the installed Nexus Repository License if the container is restarted.

Another environment variable can be used to control the Nexus Context Path

NEXUS_CONTEXT, defaults to /
This can be supplied at runtime:

$ docker run -d -p 8081:8081 --name nexus -e NEXUS_CONTEXT=nexus sonatype/nexus3

Persistent Data（持久化数据）
There are two general approaches to handling persistent storage requirements with Docker. See Managing Data in Containers for additional information.

Use a docker volume. Since docker volumes are persistent, a volume can be created specifically for this purpose. This is the recommended approach.

$ docker volume create --name nexus-data
$ docker run -d -p 8081:8081 --name nexus -v nexus-data:/nexus-data sonatype/nexus3

Mount a host directory as the volume. This is not portable, as it relies on the directory existing with correct permissions on the host. However it can be useful in certain situations where this volume needs to be assigned to certain specific underlying storage.

$ mkdir /some/dir/nexus-data && chown -R 200 /some/dir/nexus-data
$ docker run -d -p 8081:8081 --name nexus -v /some/dir/nexus-data:/nexus-data sonatype/nexus3
