Generally speaking, there are few server problems. The server? Once there is a problem with website rental, how to actively rescue it? We can't wait to die, because once the server crashes, all the websites on the server will not be open. For an enterprise, the website is their lifeblood, with huge losses. It is also a devastating blow to SEOER. Finally, it appeared on the homepage of the search engine, but disappeared due to the failure of the server. Here, taking the server as an example, we will tell you three basic reasons for server failure and how to solve them.

First, for the server network card, please check the usage of your server 1. Either 1. CPU utilization is greater than 50%. 2. Whether the memory utilization rate is too high. 3. Is the network utilization rate too high? If the above situation indicates that your server or network cannot host your current service, you can contact the service provider. If the above situation does not occur, it may be caused by the following reasons: 1. Since the server is attacked by CC, you need to contact after-sales personnel to understand CC protection strategy. 2. The server was attacked by traffic congestion, but the server was not dragged down by traffic. 3. Equipment network card failure, network cable failure, upper layer switch failure. Before failing, you can test the adjacent ip of your server. If data packets are lost from adjacent IPs, this is the fault of the upper layer switching equipment. 4. The computer room network failure will be a large-scale failure. In the case of server card, the general performance is: 1. The server has serious packet loss, and the normal packet loss rate of the server is 0%. If the packet loss rate is higher than 1%, a card will appear. 2. Some users have cards, and some users do not. It may be caused by the hardware firewall, and some links are blocked. 3. In addition, the above situation may also be caused by Internet node failure. If it is a card, please make the following judgment so that the technology can accurately judge the fault. 1. Please check whether your LAN is normal first.

If it is not a local network problem, it may be a server failure. Local network detection method: ping your server and ping other websites. If the loss of data packets from your server is serious, but the loss of data packets from other servers is not serious, it means that the fault is in your server 2. Please confirm whether your server has card users. Generally speaking, all user cards or some user cards are users of a specific card.

Second, the server cannot connect. The possible situations are as follows: 1. Due to the attack of heavy traffic, the server was dragged down by the traffic. 2. The server hardware is damaged, causing the server to crash or shut down. 3. The network is interrupted or the operating system cannot be accessed due to the incorrect configuration of server 4. After being hacked, the system is maliciously damaged. 5. The upper switchgear fails. 6. The computer room network fails. The test method is similar to the network card. In short, server failure is an unexpected event, and no one can predict it. As long as we prevent and monitor, pay attention to the above problems, and find appropriate solutions, the losses caused by failures can be eliminated.
