步骤如下：
1.先将本地maven/localrepository仓库打一个完整的zip压缩包
2.上传到linux目录，如：/opt
3.解压localrepository.zip
4.进入/opt/localrepository目录
5.1-4步，可以通过FTP/SFTP工具，直接将本地localrepository上传到/opt/localrepository

6.创建touch mavenimport.sh脚本，写入以下内容；

#!/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}/{} ;

7.输入chmod a+x mavenimport.sh进行可执行授权
8.执行导入命令 (注意：将地址换成自己的私服地址)

./mavenimport.sh -u admin -p admin123 -r http://192.168.92.11:9999/nexus/content/repositories/thirdparty/

9.等待全部导入完毕后，在Nexus上刷新即可看到已导入的jar
