有个机器上的服务可能会炸掉，在修复之前直接重启。懂不懂let it crash.哲学

bash 复制代码 
#!/bin/bash
 
PORT=端口
SERVICE_NAME=服务名称
 
if ! nc -z localhost $PORT; then
    echo "Port $PORT is not active. Attempting to start $SERVICE_NAME..."

    systemctl start $SERVICE_NAME

    if systemctl is-active --quiet $SERVICE_NAME; then
        echo "$SERVICE_NAME has been started successfully."
    else
        echo "Failed to start $SERVICE_NAME."
    fi
else
    echo "Port $PORT is active."
fi
