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

Docker安装

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
