他做的还是销售工作，每天卑躬屈膝，忙死忙活，一个月才两千多的工资，是启明给了他一个当作家的机会。Although it makes people uncomfortable that Qu Goblins are superior to others, you Fan Shengmei do not like to curry favor with others or flatter others. But can't afford to be taunted or to hide? It happened that he refused to show weakness. Take a step back and you won't die. When you have the chance, you can return it well. A little more noble, like Andy's big pattern, a little wider heart can't.学者根据论文数量和获得的研究费而受到评价，年轻的研究者以不稳定的身份作为廉价劳动力被消费的现状。也有人指出，不能安心埋头研究的环境会产生道德危机。我这么大了，还害你操心，出嫁了也不得安，这么晚了不陪姐夫和外甥，倒来劝我，我怪不好意思的。At the moment, let's do an experiment.In the scanning state, the file cannot be operated, neither can it be paused nor deleted, but can only wait for the scanning to complete. After the scan is completed, judging from the MD5 value of the file, if it is confirmed that the file already exists in the server, it directly jumps to the upload completion state. If the size of the file exceeds the maximum allowed upload, or the file is corrupted, the upload failure state is skipped. Only in the rest of the case will it enter the upload state. During the upload process, you can click the Pause button to pause the upload. After pause, clicking the same button will continue the upload. In the process of scanning and uploading, clicking the Delete button is invalid. Only after pausing, uploading is completed and uploading fails can the file be deleted.In the last article, we explained Redis' master-slave cluster mode in detail. In fact, the configuration of this cluster mode is very simple. It only needs to be configured on Slave's nodes. The configuration of Master's master node does not need to be changed. However, one thing is that the persistent configuration of Master and Slave nodes should be consistent as far as possible, otherwise there will be strange problems. Starting today, we will begin to talk about the second mode of Redis cluster mode. That is, the "Sentinel" mode, which was provided from version 2.6 of Redis, but the mode of this version was unstable at that time. The Sentinel mode did not stabilize until version 2.8 of Redis. In the production environment, if you want to use the Sentinel mode of Redis, you will try to use the version after version 2.8 of Redis. Whether it is master-slave mode or sentinel mode, both modes have a problem and cannot be expanded horizontally, and the high availability of these two modes will be limited by the memory of Master master node. Another point is that the configuration of Sentinel mode is not simple or even complicated, so neither mode is recommended in industrial scenes. If you want to use it, you must have solutions to related problems to avoid subsequent problems.
