How should the daily maintenance of the server be done?

I. Database services

After the database has been running for a long time, it is necessary to adjust the performance of the database to make it enter the best state. The data in the database is the most important. If these databases are lost, the loss is huge, so it is necessary to back up the databases regularly, just in case.

Second, the maintenance of operating system

Operating system is the software foundation of server operation, and its importance is self-evident. Most server operating systems use Windows 2003 or Windows 2008 Server as the operating system, which is relatively easy to maintain.

Open the event viewer in Windows NT or Windows 2003 Server, and check whether there are any special abnormal records in the system log, security log and application log. Now there are more and more hackers on the Internet, so it is necessary to download the latest service package (upgrade service package) from Microsoft's website and install it to make up for security loopholes in time.

Third, user data.

After frequent use, the server may store a large amount of data. These data are very valuable resources, which need to be sorted out and carved into CDs for permanent storage, and even if the server fails, the data can be recovered.

Fourth, the maintenance of network services.

There are many network services, such as WWW service, DNS service, DHCP service, SMTP service, FTP service and so on. With more and more services provided by servers, the system is prone to confusion. At this time, it may be necessary to reset the parameters of each service to make it run normally.

Hardware maintenance

First, dust removal

Dust is the biggest killer of the server, so it is necessary to dust the server regularly. For the server, dust is even fatal. The dust removal method is the same as ordinary PC, especially the dust removal of power supply.

Second, the expansion of storage devices.

When resources expand, the server needs more memory and hard disk capacity to store these resources. So the expansion of memory and hard disk is very common. Before adding memory, you need to confirm the compatibility with the original memory of the server, preferably the memory of the same brand and specification. If ECC memory is dedicated to the server, you must select the same memory. Using common SDRAM memory and ECC memory on the same server may cause serious errors in the system. Before adding a hard disk, it is necessary to determine whether the server has a spare hard disk bracket, hard disk interface and power interface, and whether the motherboard supports this capacity of hard disk. In particular, we should pay attention to prevent the equipment from being used when it is bought back.

Third, the unloading and replacement of equipment.

There are no major problems when unloading and replacing equipment. It should be noted that many brand server shells are specially designed and need special tools or mechanisms to open them. When taking off the cover of the shell, you need to read the instructions carefully and don't take it off by force. In addition, even the equipment that supports hot plug must be carried out when the server is completely powered off and well grounded to prevent static electricity from damaging the equipment.
