This article introduces the relevant knowledge of "what is the daily maintenance of VPS?". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

If you want vps to run stably for a long time, you must do a good job in the maintenance of vps, otherwise there will be frequent problems. Without maintenance, it is easy to cause problems such as too much garbage, low security and easy to be invaded, which will seriously affect the normal operation of vps, so users need to arrange technical personnel with certain professional knowledge to maintain vps after activating vps, individual webmasters can maintain it themselves, friends who do not know how to maintain can find maintenance agents to help maintain, and at the same time, they can learn how to maintain vps and reduce maintenance costs. Reduce the economic pressure on users.

The maintenance of vps is not simply to install an antivirus software on vps, but also includes system security, super administrator account password security, program software security, port security, permission security and so on. Immediately after opening vps, modify the login account password, and then set a trap account, the new password should be as complex as possible, not too simple, and the password should be modified regularly to avoid being violently cracked by hackers; regularly check system vulnerabilities and patch them in time, and also need to upgrade the virus database regularly; install legitimate program software, and upgrade the program software to the latest version in time Modify important ports, close unnecessary ports and services, and set read and write permissions for some hard drives and websites, do anti-access settings, and so on.

Especially for our VPS novice webmaster, after choosing the VPS host, we may only install a WEB panel, and then build the website, and then we may see that there will be no problems. If there is a problem, we may be at a loss and complain about the merchant and the panel. In fact, most of the time when we use VPS, we also need some maintenance and monitoring.

First, check the memory usage.

The code is as follows:

Free-m

Use this command to detect memory usage and usage. If the CPU is high, we need to check whether it is due to the normal increase caused by large website visits. At this time, we need to upgrade and configure higher CPU resources. If there are abnormal reasons, we need to check whether the load caused by attack or other reasons is too high.

Second, check the website access log

From the website log, you can not only see the crawling of the search engine of the site, but also see whether users have normal access or malicious access from unknown sources. If we are using LNMP or LLSMP, we can use "open LNMP site access log analysis site log file" and "set LiteSpeed log option to open site access log file" to turn on the log function, and then download it to the local for analysis.

Third, check the use of the hard disk

Check the use of hard disk partitions through df-hl. With the accumulation of running time of the website, a lot of buffered files and data of the website may be generated. We need to check whether there is a need to empty the buffered files or upgrade the hard drive.

Fourth, check the load and running status of the VPS host system

Through the uptime or probe file page, you can observe the operating time of VPS hosts and whether there are problems such as downtime. We can also use some free or paid monitoring tools. If there is an outage, you can send us email or SMS to deal with it in a timely manner.

Fifth, back up website data on a regular basis

Whether we use regular automatic backups or regular manual backups, VPS hosts are different from virtual hosts, we need to back up our own data, maybe virtual hosts and merchants give us regular backups, but the best thing is to back up our own. This prevents businesses from running away, VPS hanging can not be restored, a variety of possible uncertain reasons, because website data is the most important.
