关于linux上文件同步操作 inotify-tools

1. 安装 inotify-tools 插件（易可源码安装）

sudo apt-get update
sudo apt-get install inotify-tools
#或者
sudo yum install inotify-tools

2. 编写测试脚本（如果脚本执行不成功，可能需要ssh-keygen 证书授权）

#!/bin/bash

# Get the current user
CURRENT_USER="$USER"

# Source and destination folders
SOURCE_FOLDER="/path/to/source/folder"
DESTINATION_HOST="username@destination_host"
DESTINATION_FOLDER="/path/to/destination/folder/$CURRENT_USER"

# Log file
LOG_FILE="/path/to/log/file.log"

# Function to sync files using rsync
sync_files() {
    rsync -avz --delete "$SOURCE_FOLDER/" "$DESTINATION_HOST:$DESTINATION_FOLDER/"
}

# Function to log changes
log_change() {
    echo "$(date): Change detected by $CURRENT_USER - $1 $2" >> "$LOG_FILE"
}

# Monitor changes using inotifywait
while true; do
    inotifywait -r -e modify,create,delete,move "$SOURCE_FOLDER" |
    while read path action file; do
        log_change "$action" "$file"
        sync_files
    done
done

3. 启动脚本

#脚本后台运行01
nohup ./your_script.sh > script_output.log 2>&1 &
#后台运行脚本02
npm install -g pm2
pm2 start your_script.sh --name your_script
pm2 logs your_script

4. 查看运行时日志
