Many beginners are not very clear about how to maintain ecs CVM. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

How to maintain ecs CVM? Cloud computing technology is becoming more and more mature, and now most IDC suppliers provide cloud server rental services. In order to provide users with a stable website running environment, as server operation and maintenance personnel, the daily work is to maintain and check the server.

Monitor the load and running status of the host system

Through the uptime or probe file page, you can observe the operating time of the CVM 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 an email or SMS to deal with it in time.

Check memory usage regularly

We can use the command "free-m" to detect memory usage and usage. If the CPU footprint is too high, we need to check the website visits to determine the cause of the excessive CPU footprint. If the normal increase is due to the large number of visits to the website, then we need to improve the host rental configuration. If there is an increase in traffic, then we need to see if the CPU is overloaded by a ddos attack or some other reason.

Check the use of the hard drive regularly

We can check the use of hard disk partitions through df-hl. With the accumulation of running time of the website, the data of the website continues to increase, and the need to buffer data takes up hard disk space, so we need to check whether the buffered files need to be cleaned or the cloud storage space is insufficient and the hard disk needs to be upgraded.

Check the website access log regularly

If we are using LNMP or LLSMP, we can use "enable LNMP site access log analysis site log file" and "set LiteSpeed log option to enable site access log file" to turn on the log function, and then download it to the local for analysis. From the website log, you can see the crawling website of the search engine, you can also detect the access path of the website visitors, and you can also monitor whether it is the normal visit of the user.

Make regular backups of website data

There are two methods of website data backup: regular automatic backup and manual backup, but either way, the CVM needs to back up the data by ourselves, and there may be a cloud service provider to back up the data for us on a regular basis. but the most guaranteed way is to back up by yourself. This prevents businesses from running away, hosts hanging and unable to recover, and a variety of possible uncertain reasons, because website data is the most important.
