After purchasing a CVM, many users will find high-risk vulnerabilities in the server for a period of time, and there are many kinds of vulnerabilities, including high-risk / medium-risk / low-risk / serious.

Generate repair commands are provided, but this is only available for the enterprise version and is free of charge. If you fix it manually, you can generally solve it by using software upgrades. Except for those that indicate high-risk vulnerabilities with kernel, they can be repaired without restarting the instance. If there is a need to update the kernel, restart the instance.

Users can first search the "vulnerability name" in the browser, and then deal with it according to the method found. If there is no solution online, the simplest and rudest way is to upgrade and update the system software. The repair process is as follows:

Root login

Yum upgrade upgrades all upgradeable system software

Wait for the execution to be completed, and then log in to the console of Ali CVM for verification. Wait about 3-5 minutes to refresh the page.
