This article does not discuss the management of computer rooms and servers, but only describes how to maintain windows virtual machines continuously and efficiently .
The operation and maintenance management of windows virtual machine resources should be composed of the following six dimensions:
1. Virtual machine information document; 2. Operating system environment inspection; 3. Operating system patch upgrade; 4. Application middleware environment inspection; 5. Application program inspection; 6. Database inspection
First of all, 1 is to be "knowledgeable" about the virtual machine resources at hand, which is the first step in management. 2.3.4 is mainly for manual configuration and upgrade maintenance for the "middle ground" of non-code and data. 5.6 is for code and data synchronization, backup and inspection.
The following describes the inspection cycle , inspection content , and operation list for each dimension .
1. Computer room, virtual machine, program, user and system information documents
Inspection cycle: one week.
Inspection content: Check whether there is any change in these five types of information within this week, and if so, modify it.
Operation checklist:
--1.VPN/remote client installation and connection.
--2. Use the ping command to view the network direction of the domain name or ip.
*If you are new to a project, this part of the effort is definitely worth it, you can finally know where to change what you want to change!
2. Use security software to inspect the operating system environment
Inspection cycle: one week.
Inspection content: check the remaining disk space, scan and process system vulnerabilities, scan and process system repairs, scan and process system garbage, inspect and process system startup items, and inspect and process system services.
Operation checklist:
1. Check the remaining space of each disk in "Computer" and calculate the remaining proportion. If it is less than the threshold, an alarm will be issued.
2. In "Uninstall a program" in "Control Panel", check Uninstall unwanted apps. Record uninstallation.
3. Log in to the official website of Huorong , and download the latest version of Huorong. (Can be ignored if installed)
Click "Free Download" for individual users to install
4. Copy the installation package to the server, install to the default disk, and install security tools. (Can be ignored if installed)
Click "Security Tools" to enter and install more management tools
Click the picture in the red box to automatically download the installation tool
Note: If access to the external network is restricted on the virtual machine, you can directly download the "full version" in the personal version. The download address of the full version is as shown in the figure:
After installing this in the server, it will prompt that the service is abnormal, and only security tools can be used.
5. Execute the inspection operation and record the inspection log
(1) Vulnerability repair (network is required, and the system does not support winserver), execute the repair, and record the number of repairs. If this function cannot be used, you need to perform the third step "3. Regularly upgrade the operating system patch" to repair the system vulnerabilities by yourself patch.
(2) Virus killing (requires network), if there is no network, it can be ignored, if there is, record the killing result.
(3) Garbage cleaning, record the size of the cleaning.
(4) System repair, record repair items.
(5) Start item management and record changes.
3. Regularly upgrade the operating system patches
Inspection cycle: January.
Inspection content: If the virtual machine cannot access the external network and Tinder cannot be used, windows update can be manually upgraded.
Operation checklist:
1. Check whether there is an upgrade package in the system and upgrade it.
2. Solve the problem of repeated upgrades that always fail.
4. Application middleware environment configuration and version upgrade
Inspection cycle: half a year.
Inspection content: Apache, PHP, MySQL version upgrades and property configuration inspections, OPENSSL, PHPStudy, Huorong, SVN version upgrades.
Operation checklist:
--1. Server application environment deployment checklist.
--2.Apache attribute configuration and upgrade list.
--3.PHP attribute configuration and upgrade list.
--4. MySQL attribute configuration and upgrade list.
--5. OPENSSL upgrade list.
--6.PHPStudy upgrade list.
--7. Tinder upgrade list.
*Here take phpstudy+Apache+php+MySQL as an example
5. Application function verification and data and code backup
Inspection cycle: one week / one month.
Inspection content: program code SVN backup, planned task inspection, online execution task inspection.
Operation checklist:
--1. SVN update check and conflict resolution list.
--2. Planning task deployment and checklist.
6. Database function, log and business data inspection
Inspection cycle: one week / one month.
Inspection content: database operation log, database table status, business data inspection.
Operation checklist:
--1. Database restart and table repair list.
