Briefly introduce the daily maintenance of the server

In order to better use and extend the life of the server, regular maintenance of the server is necessary. However, when maintaining the server, you must carefully handle the maintenance work, otherwise it will have a big impact if there is an error. In order to facilitate everyone to understand some maintenance content while maintaining, while avoiding errors. Here are some of the information collected for your reference.

Hardware Maintenance

1. Expansion of Storage Devices

As resources continue to expand, the server needs more memory and hard disk capacity to store these resources. Therefore, the expansion of memory and hard disk is very common. Before adding memory, you need to determine compatibility with the original memory of the server, preferably the same brand of memory. If it is server-specific ECC memory, you must use the same memory. Normal SDRAM memory and ECC memory on the same server may cause serious errors. Before adding a hard disk, you need to determine whether the server has spare hard disk brackets, hard disk interfaces and power connectors, and whether the motherboard supports such capacity hard disks. In particular, you need to be careful not to buy equipment that you can't use.

2, equipment unloading and replacement

There are not many problems when uninstalling and replacing equipment. It should be noted that there are many brand server chassis designs that are special and require special tools or organs. Open, when you unload the cover, you need to read the instructions carefully, and do not forcefully disassemble. In addition, it must be done with a complete power outage and good server grounding, even for hot-swappable devices to prevent static damage to the device.

3, dust removal

Dust is the biggest killer of the server, so you need to regularly dust the server. For servers, dust is even fatal. The dust removal method is the same as the ordinary PC dust removal method, and in particular, the dust removal of the power source is required.

Software Maintenance

1. Maintenance of Operating System

The operating system is the software foundation for the operation of the server, and its importance is self-evident. Most server operating systems use Windows NT or Windows 2000 Server as the operating system, and it is relatively easy to maintain.

Open the Event Viewer on Windows NT or Windows 2000 Server and check the system log, security log, and application logs for any unusual exceptions. Now there are more and more hackers on the Internet, so you need to download the latest service pack (upgrade service pack) on the Microsoft website to install security vulnerabilities.

2, network service maintenance

There are many network services, such as WWW service, DNS service, DHCP service, SMTP service, FTP service, etc., with more and more services provided by the server The system is also easy to be confused. At this time, it may be necessary to reset the parameters of each service to make it run normally.

3, database services

After a long-term operation of the database, you need to adjust the database performance to make it into an optimal state. The data in the database is the most important. If these databases are lost, the loss is huge, so you need to back up the database regularly, just in case.

4, user data

After frequent use, the server may store a large amount of data. These data are invaluable resources, so they need to be sorted out and burned to the disc for permanent storage, even if the server is faulty.
