在小米AX6000中添加tailscale monitor

article 2025/3/25 11:12:48

经过测试，发现小米路由器中的tailscale可能会因为某种原因状态异常，
为了让tailscale恢复正常，所以又写了monitor用来监控：

#!/bin/sh

# Define Tailscale related paths
TAILSCALED_PATH="/tmp/tailscale/tailscale_1.80.3_arm/tailscaled"
TAILSCALE_PATH="/tmp/tailscale/tailscale_1.80.3_arm/tailscale"
LOG_DIR="/etc/tailscale"
LOG_FILE="$LOG_DIR/tailscale_monitor.log"
LOOP_TIME=600

# Create log directory
mkdir -p "$LOG_DIR"

# Function: Log messages
log() {
    echo "$1"
    echo "$(date '+%Y-%m-%d %H:%M:%S') - $1" >> "$LOG_FILE"
}

# Function: Check and start Tailscale
start_tailscale() {
    "$TAILSCALE_PATH" up --advertise-routes=192.168.0.1/24 >> "$LOG_FILE" 2>&1 &
    if [ $? -eq 0 ]; then
        log "Tailscale started successfully."
    else
        log "Failed to start Tailscale."
    fi
}

# Function: Check and start Tailscaled
start_tailscaled() {
    if [ -z "$(pgrep -f "$TAILSCALED_PATH")" ]; then
        log "Tailscaled is not running, starting..."
        "$TAILSCALED_PATH" >> "$LOG_FILE" 2>&1 &
        if [ $? -eq 0 ]; then
            log "Tailscaled started successfully."
            start_tailscale
        else
            log "Failed to start Tailscaled."
        fi
    else
        log "Tailscaled is already running."
    fi
}

# Function: Check Tailscale status
check_tailscale_status() {
    log "Checking Tailscale status..."
    STATUS=$("$TAILSCALE_PATH" status 2>&1)
    log "$STATUS"
    if echo "$STATUS" | grep "xiaomi-ax6000"; then
        log "Device xiaomi-ax6000 found."
        LINE=$(echo "$STATUS" | grep "xiaomi-ax6000")
        FOURTH_FIELD=$(echo "$LINE" | awk '{print $5}')
        if [ "$FOURTH_FIELD" = "offline" ]; then
            log "Device xiaomi-ax6000 is offline, restarting Tailscale..."
            #pkill -f "$TAILSCALE_PATH"
            start_tailscaled
        else
            rm $LOG_FILE
            log "Device xiaomi-ax6000 status is normal: $FOURTH_FIELD"
        fi
    elif echo "$STATUS" | grep "Tailscale is stopped"; then
        log "Tailscale is stopped"
        "$TAILSCALE_PATH" up
    else
        log "Device xiaomi-ax6000 not found."
        start_tailscale
    fi
}

# Main logic
while true; do
    log "Starting Tailscale status check..."
    start_tailscaled
    #start_tailscale
    check_tailscale_status
    log "Check completed."
    log "Waiting for $LOOP_TIME(sec)..."
    sleep $LOOP_TIME  # Sleep for 5 minutes (300 seconds)
done
