拉取nexus3镜像
docker pull docker.io/sonatype/nexus3
控制台输出
[root@xxx ~]# docker pull docker.io/sonatype/nexus3 Using default tag: latest latest: Pulling from sonatype/nexus3 c65691897a4d: Pull complete 641d7cc5cbc4: Pull complete c508b13320cd: Pull complete 79e3bf9d3132: Pull complete Digest: sha256:2c33632ccd1f8c5f9023a3d7f5f541e211831e402219f8c5a83a29d1721457ca Status: Downloaded newer image for sonatype/nexus3:latest docker.io/sonatype/nexus3:latest
查看镜像
docker images
控制台输出
[root@xxx ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE sonatype/nexus3 latest 8eb898be2a53 2 weeks ago 611MB
4.运行nexus容器
docker run -id --privileged=true --name=nexus3 --restart=always -p 8081:8081 -v /wandou/nexus3/nexus-data:/var/nexus-data sonatype/nexus3
控制台输出
[root@xxx ~]# docker run -id --privileged=true --name=nexus3 --restart=always -p 8081:8081 -v /wandou/nexus3/nexus-data:/var/nexus-data sonatype/nexus3 980f3759783f3ba7e59302848f816e371b229957f2c12b8f92934d468e061b00
解释: -id 创建守护式容器 --privileged=true 授予root权限(挂载多级目录必须为true,否则容器访问宿主机权限不足) --name=名字 给你的容器起个名字 -p 宿主机端口:容器端口映射 -v 宿主机目录:容器目录 目录挂载 这里需要些许时间才能启动并访问nexus 事机器配置而定 5.访问nexus3 请先确保服务器的8081(视上面运行nexus容器时配置的端口而定)端口在安全组里已开启!!! 浏览器访问http://ip:8081
6.登录 进入nexus3页面后右上角有个登录的按钮点击显示登录框 nexus3默认的账号依旧是admin
但是密码已经变了具体的密码存储在nexus3的容器的nexus-data路径内的admin.password
文件内 具体操作: 1.查看nexus3容器id
docker ps
控制台显示
[root@ecs-s6-xlarge-2-linux-20190927141629 ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 980f3759783f sonatype/nexus3 "sh -c ${SONATYPE_DI…" 4 minutes ago Up 4 minutes 0.0.0.0:8081->8081/tcp nexus3
记下CONTAINER ID
:980f3759783f 2.进入容器控制台
docker exec -it 980f3759783f bash
控制台显示
[root@ecs-s6-xlarge-2-linux-20190927141629 ~]# docker exec -it 980f3759783f bash bash-4.4$ ls bin etc lib lost+found nexus-data root srv uid_entrypoint.sh var boot help.1 lib64 media opt run sys uid_template.sh dev home licenses mnt proc sbin tmp usr
3.进入nexus-data
文件夹
bash-4.4$ cd nexus-data/ bash-4.4$ ls admin.password db generated-bundles karaf.pid log restore-from-backup blobs elasticsearch instances keystores orient tmp cache etc javaprefs lock port
4.打开admin.password
文件
bash-4.4$ vi admin.password
第一行就是密码啦,复制密码用admin
帐号登录,登录以后系统会自动提示你更换admin
的密码
