搭建nexus私服，功能我就不一一列举了。好处多多。我这里选择一个openstack云主机来演示，如何通过docker这样的技术，以非常优雅的方式，自动安装好企业内部的私服服务器！

云主机信息

  • 云硬盘：Disk /dev/vdb: 1073.7 GB, 1073741824000 bytes, 2097152000 sectors
  • 系统盘：Disk /dev/vda: 53.7 GB, 53687091200 bytes, 104857600 sectors
  • 内存：8G
  • CPU: 2 core
  • Linux: CentOS Linux release 7.2.1511 (Core)

mkfs.xfs -L /data /dev/vdb  

mkdir /data

echo "LABEL=/data           /data                 xfs    defaults        0 1" >> /etc/fstab 

mount -a && mount

yum install docker -y

systemctl start docker.service

systemctl enable docker.service

Nexus安装

docker pull sonatype/nexus

  • Volume mapping to local host machine:

mkdir /data/nexus-data && chown -R 200 /data/nexus-data

docker run -d -p 8081:8081 --name nexus -v /data/nexus-data:/sonatype-work sonatype/nexus

docker logs -f nexus

  • For examples: 

    1
    2
    docker ps -l|grep Up
    9ddcacef915c        sonatype/nexus      "/bin/sh -c '${JAVA_H"   8 minutes ago       Up 4 minutes        0.0.0.0:8081->8081/tcp   nexus

  • To test:

    1
    curl http://localhost:8081/service/local/status

  • Note:
    Default credentials are: admin / admin123
