基于SSHFS的远程目录挂载脚本

#!/bin/bash
# SSHFS远程目录挂载脚本
# 使用前需要安装: sudo apt-get install sshfs
# 配置参数
REMOTE_USER="your_username"
REMOTE_HOST="192.168.1.100"
REMOTE_PATH="/home/your_username/remote_folder"
LOCAL_MOUNT="/mnt/remote"
SSH_PORT=22
SSH_KEY="~/.ssh/id_rsa"  # 可选：使用SSH密钥
# 创建挂载点
mkdir -p "$LOCAL_MOUNT"
# 挂载命令
if [ -f "$SSH_KEY" ]; then
    # 使用密钥认证
    sshfs -o allow_other,default_permissions,port=$SSH_PORT,IdentityFile=$SSH_KEY \
          $REMOTE_USER@$REMOTE_HOST:$REMOTE_PATH \
          $LOCAL_MOUNT
else
    # 使用密码认证（需要安装sshpass）
    # read -sp "请输入SSH密码: " SSH_PASS
    # export SSHPASS=$SSH_PASS
    # sshfs -o allow_other,default_permissions,password_stdin \
    #       $REMOTE_USER@$REMOTE_HOST:$REMOTE_PATH \
    #       $LOCAL_MOUNT
    # 或手动输入密码
    sshfs $REMOTE_USER@$REMOTE_HOST:$REMOTE_PATH $LOCAL_MOUNT
fi
# 检查挂载状态
if mountpoint -q "$LOCAL_MOUNT"; then
    echo "✅ 远程目录已成功挂载到 $LOCAL_MOUNT"
    echo "📊 挂载信息："
    df -h "$LOCAL_MOUNT"
else
    echo "❌ 挂载失败，请检查配置"
    exit 1
fi

NFS远程挂载脚本

#!/bin/bash
# NFS远程目录挂载脚本
# 服务端需要配置NFS服务：sudo apt-get install nfs-kernel-server
# 配置参数
NFS_SERVER="192.168.1.100"
NFS_PATH="/export/data"
LOCAL_MOUNT="/mnt/nfs_remote"
MOUNT_OPTIONS="rw,hard,intr,vers=4"
# 创建挂载点
mkdir -p "$LOCAL_MOUNT"
# 检查NFS是否可用
echo "检查NFS服务器连接..."
if ! rpcinfo -s $NFS_SERVER &>/dev/null 2>&1; then
    echo "⚠️ 无法连接到NFS服务器 $NFS_SERVER"
    exit 1
fi
# 执行挂载
mount -t nfs -o $MOUNT_OPTIONS \
      $NFS_SERVER:$NFS_PATH $LOCAL_MOUNT
# 验证挂载
if mountpoint -q "$LOCAL_MOUNT"; then
    echo "✅ NFS目录已成功挂载"
    mount | grep "$LOCAL_MOUNT"
else
    echo "❌ 挂载失败，检查:/var/log/syslog"
    exit 1
fi

Samba/CIFS挂载脚本

#!/bin/bash
# Samba/CIFS远程目录挂载脚本
# 需要安装：sudo apt-get install cifs-utils
# 配置参数
SAMBA_SERVER="192.168.1.100"
SAMBA_SHARE="shared_folder"
SAMBA_USER="windows_user"
SAMBA_DOMAIN="WORKGROUP"  # 可选
LOCAL_MOUNT="/mnt/samba_remote"
PASSWORD_FILE="/etc/samba/auth.creds"  # 密码文件
# 创建密码文件（首次使用时）
if [ ! -f "$PASSWORD_FILE" ]; then
    read -sp "请输入Samba密码: " SAMBA_PASS
    echo
    echo "username=$SAMBA_USER" | sudo tee $PASSWORD_FILE
    echo "password=$SAMBA_PASS" | sudo tee -a $PASSWORD_FILE
    echo "domain=$SAMBA_DOMAIN" | sudo tee -a $PASSWORD_FILE
    sudo chmod 600 $PASSWORD_FILE
fi
# 创建挂载点
sudo mkdir -p "$LOCAL_MOUNT"
# 执行挂载
sudo mount -t cifs \
     -o credentials=$PASSWORD_FILE,iocharset=utf8,file_mode=0644,dir_mode=0755 \
     //$SAMBA_SERVER/$SAMBA_SHARE $LOCAL_MOUNT
# 验证
if [ $? -eq 0 ]; then
    echo "✅ Samba目录已成功挂载到 $LOCAL_MOUNT"
    echo "📊 挂载信息："
    mount | grep cifs
else
    echo "❌ 挂载失败"
    exit 1
fi

使用说明

1. 保存脚本：将脚本保存为 mount_remote.sh

2. 添加执行权限：

   chmod +x mount_remote.sh

3. 安装依赖：

   # SSHFS
   sudo apt-get install sshfs
   # NFS
   sudo apt-get install nfs-common
   # Samba
   sudo apt-get install cifs-utils

4. 配置参数：根据实际情况修改脚本中的配置

5. 执行脚本：

   ./mount_remote.sh

自动挂载（/etc/fstab）

到 /etc/fstab 实现开机自动挂载：

# SSHFS
sshfs#user@host:/remote/path /mnt/local fuse defaults,allow_other,_netdev 0 0
# NFS
server:/export/path /mnt/local nfs defaults,_netdev 0 0
# Samba
//server/share /mnt/local cifs username=user,password=pass,_netdev 0 0

这些脚本提供了灵活的远程目录挂载解决方案,您可以根据实际需求选择使用。
