使用 Nexus 搭建Maven 仓库

Alan

5 年前

Nexus可通过源码等方式进行安装，最简单的方式是通过 Docker 创建同时使用 Docker Volume 进行持久化数据存储，以下使用指定的目录进行创建：

mkdir /var/nexus-data && chown -R 200 /var/nexus-data
sudo docker run -d -p 8081:8081 --name nexus -v nexus-data:/nexus-data sonatype/nexus3

1 2	mkdir /var/nexus-data && chown -R 200 /var/nexus-data sudo docker run -d -p 8081:8081 --name nexus -v nexus-data:/nexus-data sonatype/nexus3

稍等片该在浏览器中访问访问 http://your.ip.addr:8081进行访问即可：

初始化界面：

查看初始化密码：

sudo docker exec -it nexus cat /nexus-data/admin.password

1	sudo docker exec -it nexus cat /nexus-data/admin.password

点击欢迎页面的 Sign in 输入默认用户名 admin以及刚刚获取到的初始密码登录并按步骤设置密码

Nginx 配置示例

upstream nexus-server{
    server 127.0.0.1:8081;
}

server {
    listen 80;
    server_name maven.xxx.com;
    location / {
       #proxy_store off;
       #proxy_redirect  off;
       #proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
       #proxy_set_header X-Real-IP $remote_addr;
       #proxy_set_header Host $http_host;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Proto "http";
        proxy_pass http://nexus-server;
    }
}

upstream nexus-server{

server 127.0.0.1:8081;

}

server {

listen 80;

server_name maven.xxx.com;

location / {

#proxy_store off;

#proxy_redirect off;

#proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

#proxy_set_header X-Real-IP $remote_addr;

#proxy_set_header Host $http_host;

proxy_set_header Host $host;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-Proto "http";

proxy_pass http://nexus-server;

}

常见问题

1、Return code is: 400, ReasonPhrase: Repository does not allow updating assets: maven-releases.

产生这一问题的原因是不允许同版本重复部署，解决方法有：

进入录Nexus管理界面–>小齿轮图标–>Repository–>Repositories–>maven-releases，Hosted下方请选择‘Allow redeploy’
更推荐的方法是更改本地的版本号，而不是使用相同版本号打包至 Maven

2、Error occurred while executing a write operation to database ‘component’ due to limited free space on the disk (3610 MB). The database is now working in read-only mode. Please close the database (or stop OrientDB), make room on your hard drive and then reopen the database. The minimal required space is 4096 MB. Required space is now set to 4096MB (you can change it by setting parameter storage.diskCache.diskFreeSpaceLimit) . DB name=”component”. -> [Help 1]

这一问题是由于默认要求在写入时要有4GB 的空闲空间，只需修改配置文件即可，位于安装目录下的bin/nexus.vmoptions文件中，由于上面使用的是 Docker安装，Alan 暂未深入研究如何将配置文件挂载到本机中，临时解决的方案是

docker cp nexus:/opt/sonatype/nexus/bin/nexus.vmoptions /tmp
# 修改完成后再拷贝回去进行覆盖
# 如添加或修改参数-Dstorage.diskCache.diskFreeSpaceLimit=2048
docker cp /tmp/nexus.vmoptions nexus:/opt/sonatype/nexus/bin/nexus.vmoptions
docker container restart nexus

docker cp nexus:/opt/sonatype/nexus/bin/nexus.vmoptions /tmp

# 修改完成后再拷贝回去进行覆盖

# 如添加或修改参数-Dstorage.diskCache.diskFreeSpaceLimit=2048

docker cp /tmp/nexus.vmoptions nexus:/opt/sonatype/nexus/bin/nexus.vmoptions

docker container restart nexus
