5 common points for daily maintenance and inspection of VPS hosts

With the increasing cost-effectiveness of VPS hosting and the needs of our projects, more and more webmaster users choose and use VPS to build websites and projects. Especially for us novice VPS webmasters, after choosing a VPS host, we may only install a WEB panel and then build the website. Later, we may depend on God's will and there will be no problems and we can run the website stably. If a problem occurs, we may be helpless and complain about the merchant and the panel. In fact, many times we also need certain maintenance and monitoring when using VPS.

Through this article, Snail shares what aspects of daily VPS maintenance we should do to ensure that the machine can operate normally.

First, check memory usage

free -m

Use this command to check memory occupancy and usage. If the CPU is high, we need to check whether it is a normal increase due to heavy website visits. At this time, you need to upgrade and configure higher CPU resources. If the CPU is abnormally high, We need to check whether there is an attack or other reasons that cause the load to be extremely high.

Second, check the website access log

From the website log, you can not only see the crawling status of the website's search engine, but also see whether the user has normal access or malicious access from unknown sources. If we are using LNMP or LLSMP, we can use them respectively\ \"Turn on LNMP website access log analysis website log files\\" and \\"Set LiteSpeed ​​log options to turn on website access log files\\" turn on the log function, and then download it to the local for analysis.

Third, check the hard disk usage

Check the usage of the hard disk partition through df -hl. As the running time of the website accumulates, many buffer files may be generated and the data of the website continues to increase. We need to check whether it is necessary to clear the buffer files or upgrade the hard disk.

Fourth, check the VPS host system load and operating status

Through the uptime or probe file page, you can observe the operating hours of the VPS host and see if there are any downtime and other problems. We can also use some free or paid monitoring tools. If there is any downtime, we can send it via email or text message. Give us prompt processing.

Fifth, back up website data regularly

Whether we use scheduled automatic backups or regular manual backups, VPS hosts are different from virtual hosts. We need to back up our own data. Maybe the virtual host and the merchant provide us with regular backups, but the best thing is to back up our own data. . This prevents merchants from running away, VPS hangs up and cannot be restored, and various possible uncertain reasons, because website data is the most important.

In short, VPS hosting may cause us to worry more than virtual hosting. Snail suggests that if we have a regular and long-term website, we should buy a stable (cheap and not necessarily good) machine, which will be less stable. .
