Most IDC providers provide cloud server rental service. In order to provide users with a stable website running environment, as server operation and maintenance personnel, their daily work is to maintain and check the server.

1. Check the use of the hard drive regularly

We can check the use of hard disk partitions through df-hl. With the accumulation of the running time of the website, the data of the website continues to increase, and it also needs to buffer data to occupy the hard disk space, so we need to check whether the buffered files need to be cleaned or there is insufficient space to upgrade the hard disk.

two。 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 caused by heavy visits to the website, you need to improve the CPU configuration of the CVM. If there is an increase in traffic, then we need to see if the host is under ddos attack or some other reason causing the CPU load to be too high.

3. Real-time monitoring of system load and operation status

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 email or call the cloud service provider to deal with it in a timely manner.

4. 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, we can not only see the crawling website of the search engine, but also detect the access path of the website visitors, and also monitor whether it is the normal visit of the user.

5. Make regular backups of website data

The backup of a CVM is different from that of a virtual host. There are two methods of website data backup: regular automatic backup and manual backup, but no matter which way, we need to back up the data ourselves, and there may be merchants to back up our data regularly, but the most guaranteed way is to back up by ourselves. 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.
