如何搭建一个纯离线的nexus3

Maven 篇

0. 在离线的nexus3服务器上创建所需的本地依赖仓库。（如果已经创建了依赖仓库文件夹，这个步骤可以忽略）-登录具有创建仓库权限的用户，这里使用默认用户admin示范。

创建新的仓库

选择hosted格式的maven2仓库

选择允许依赖的要求，其他默认

1. 准备所需的依赖文件-主体的思想就是将项目所需的依赖jar包先下载好，然后使用脚本提交到离线的nexus仓库

1.  方式一：先将项目在自己本地构建一遍，构建成功后将使用的本地仓库打包，复制到nexus服务器上，或者能访问到nexus的主机.

2. 创建脚本

创建脚本

# 创建脚本
vim mavenimport.sh

写入脚本命令

#!/bin/bash
# copy and run this script to the root of the repository directory containing files
# this script attempts to exclude uploading itself explicitly so the script name is important
# Get command line params
while getopts ":r:u:p:" opt; do
	case $opt in
		r) REPO_URL="$OPTARG"
		;;
		u) USERNAME="$OPTARG"
		;;
		p) PASSWORD="$OPTARG"
		;;
	esac
done

find . -type f -not -path './mavenimport\.sh*' -not -path '*/\.*' -not -path '*/\^archetype\-catalog\.xml*' -not -path '*/\^maven\-metadata\-local*\.xml' -not -path '*/\^maven\-metadata\-deployment*\.xml' | sed "s|^\./||" | xargs -I '{}' curl -u "$USERNAME:$PASSWORD" -X PUT -v -T {} ${REPO_URL}/{} ;

3. 执行脚本

将上传到服务器的文件解压，进入文件夹内部
执行如下命令，记得替换[]中的内容

mavenImport.sh -u [nexus3账户] -p [nexus3密码] -r http://[IP]:[端口]/repository/[仓库名称]/

npm 篇

0. 创建npm仓库，步骤同上，展示创建配置，悬着npm类型的仓库

配置展示

1. 现在本地打包构建，获取到package-lock.json，或者 yarn-lock.json

2. 根据获取到的文件，执行下列Python脚本，进行下载对应的npm包。

npm 执行如下脚本

import os
import re
import aiohttp
import asyncio
from urllib.parse import urlparse
from concurrent.futures import ThreadPoolExecutor

# 创建存储文件夹
download_folder = "sourcenpm"
os.makedirs(download_folder, exist_ok=True)

# 读取文件内容
with open("pack.json", "r") as file:
    content = file.read()

# 使用正则表达式匹配resolved字段的值
pattern = r'"resolved":\s+"(https:\/\/[^"]+\.tgz)"'
matches = re.findall(pattern, content)

# 异步下载函数
async def download_file(session, url):
    async with session.get(url) as response:
        if response.status == 200:
            parsed_url = urlparse(url)
            filename = os.path.basename(parsed_url.path)
            full_filename = os.path.join(download_folder, filename)
            
            content = await response.read()
            with open(full_filename, "wb") as output_file:
                output_file.write(content)
            
            print(f"文件 {filename} 下载成功")
        else:
            print(f"无法下载文件 {url}")

async def download_with_semaphore(semaphore, session, url):
    async with semaphore:
        await download_file(session, url)

async def main():
    # 创建异步HTTP会话
    async with aiohttp.ClientSession() as session:
        semaphore = asyncio.Semaphore(8)  # 限制并发数为8
        tasks = []

        for url in matches:
            tasks.append(download_with_semaphore(semaphore, session, url))

        await asyncio.gather(*tasks)

    print("下载完成")

# 运行异步下载
if __name__ == "__main__":
    asyncio.run(main())

yarn 执行如下脚本

import os
import re
import aiohttp
import asyncio
from urllib.parse import urlparse
from concurrent.futures import ThreadPoolExecutor

# 创建存储文件夹
download_folder = "sourcenpm"
os.makedirs(download_folder, exist_ok=True)

# 读取文件内容
with open("yarn.lock", "r") as file:
    content = file.read()

# 使用正则表达式匹配resolved属性中的tgz下载链接
pattern = r'resolved\s+"(https:\/\/[^"]+\.tgz)'
matches = re.findall(pattern, content)

# 异步下载函数
async def download_file(session, url):
    async with session.get(url) as response:
        if response.status == 200:
            parsed_url = urlparse(url)
            filename = os.path.basename(parsed_url.path)
            full_filename = os.path.join(download_folder, filename)
            
            content = await response.read()
            with open(full_filename, "wb") as output_file:
                output_file.write(content)
            
            print(f"文件 {filename} 下载成功")
        else:
            print(f"无法下载文件 {url}")

async def download_with_semaphore(semaphore, session, url):
    async with semaphore:
        await download_file(session, url)

async def main():
    # 创建异步HTTP会话
    async with aiohttp.ClientSession() as session:
        semaphore = asyncio.Semaphore(8)  # 限制并发数为8
        tasks = []

        for url in matches:
            tasks.append(download_with_semaphore(semaphore, session, url))

        await asyncio.gather(*tasks)

    print("下载完成")

# 运行异步下载
if __name__ == "__main__":
    asyncio.run(main())

3. 上传下载好的文件，执行如下脚本

创建脚本

vim npmimport.sh

写入脚本内容

find . -type f -name '*.tgz'  | sed "s|^\./||" | xargs -I '{}' \
curl -u "$USERNAME:$PASSWORD" -X 'POST' -v \
  ${REPO_URL} \
  -H 'accept: application/json' \
  -H 'Content-Type: multipart/form-data' \
  -F 'npm.asset=@{};type=application/x-compressed' ;

将上传文件解压，将脚本放入需要上传的根目录中，执行如下命令执行上传

./npmimport.sh -u [nexus3账号] -p [nexus3密码] -r http://[ip]:[端口]/service/rest/v1/components?repository=[仓库名称]
