rsync 文件同步技能

使用 rsync 高效同步文件和目录。当用户要求复制服务器之间的文件、同步目录、创建增量备份、部署文件到远程服务器或高效镜像目录时使用。

rsync 文件同步技能 是什么?

该技能提供了使用 rsync 进行高效文件同步的详细指南。rsync 是标准工具,支持增量传输、SSH 加密、文件权限保留等功能,非常适合备份、部署和目录镜像等场景。技能包含基础用法、常见模式(如排除特定目录、带宽限制、增量备份)以及一个完整的部署脚本示例。它支持本地和远程(通过 SSH)同步,并强调了使用 --delete 前先用 -n 进行试运行以避免数据丢失等最佳实践。适用于任何需要文件同步的开发或运维任务。

rsync

概述

rsync 是用于高效文件同步的标准工具。它仅传输文件中已更改的部分(增量传输),支持 SSH,处理文件权限,并适用于备份、部署和目录镜像。

操作说明

步骤1:基础用法

# 同步本地目录
rsync -avz source/ destination/
# -a = 归档模式(保留权限、时间戳、符号链接)
# -v = 详细输出
# -z = 传输时压缩

# 同步到远程服务器
rsync -avz ./dist/ deploy@server:/var/www/myapp/

# 从远程同步
rsync -avz deploy@server:/var/log/myapp/ ./logs/

# 试运行(显示将要更改的内容,但不实际执行)
rsync -avzn source/ destination/

步骤2:常见模式

# 部署网站(删除目标中不存在的源文件)
rsync -avz --delete ./build/ deploy@server:/var/www/site/

# 带排除项的备份
rsync -avz --exclude='node_modules' --exclude='.git' --exclude='.env' \
  /opt/myapp/ /backups/myapp/

# 使用硬链接的增量备份(节省空间)
rsync -avz --link-dest=/backups/latest \
  /opt/myapp/ /backups/$(date +%Y%m%d)/
ln -snf /backups/$(date +%Y%m%d) /backups/latest

# 带宽限制(适用于大文件传输)
rsync -avz --bwlimit=5000 source/ destination/    # 5000 KB/s

步骤3:部署脚本

#!/bin/bash
# scripts/deploy.sh — 使用 rsync 部署应用
SERVER="[email protected]"
REMOTE_DIR="/var/www/myapp"

echo "正在构建..."
npm run build

echo "正在同步文件..."
rsync -avz --delete \
  --exclude='node_modules' \
  --exclude='.env' \
  --exclude='.git' \
  ./dist/ ${SERVER}:${REMOTE_DIR}/

echo "正在重启服务..."
ssh ${SERVER} "sudo systemctl restart myapp"

echo "部署完成!"

使用指南

  • 使用 --delete 时,务必先用 -n(试运行)以避免意外数据丢失。
  • 尾部斜杠至关重要:source/ 同步目录内容,source 同步目录本身。
  • 对于大文件传输,添加 --progress 以查看每个文件的进度。
  • rsync 通过 SSH 传输时默认加密——适用于互联网传输。
