Ask some server related questions, what are the common problems of servers?

Server this thing,As long as you can provide services, whether you are DIY equipment or professional server equipment, it can be a server,Whether you are an ordinary PC or a PC server,Blade server,Small computer are the same,It's just that the assembled PC is configured to provide services,This is called a DIY server,The server is divided into high, medium and low-end,These servers are specially manufactured by equipment manufacturers to provide services for use,Configuration,Performance,Stability, etc.,There must be a difference with DIY ( The specific difference can be known according to the configuration of accessories and stress tests), this is the hardware level, the software level depends on your technical capabilities and needs to deploy different systems, different applications to achieve your needs.

I helped you find a netizen, I hope it can help you.

See how you make it happen. If you put all the web pages in one of the web hosting spaces provided by **, then the web pages will be accessible regardless of your computer.

If you use your own computer as a server, then the computer must be turned on, connected to the Internet, and the web service (IIS Apache, etc.) must be started, and the web page files must be located in the correct directory (see the settings of the software such as iis Apache for the specific directory). It is necessary to have a public IP (static dynamic, if it doesn't matter if dynamic, just use DDNS software such as peanut shell to solve the problem) or have a correct port mapping at the gateway (usually a computer or broadband router connected to the Internet), so as to ensure that the web page can be accessed by other computers on the Internet. You can choose to find a suitable web host on the Internet to store your**, space plus domain name more than 200 yuan a year can get a basic, 300 500 space can already be a pretty good small **.

Finally, let's talk about the computer configuration used as a server, the memory does not have to be very large, the CPU does not have to be very good, but you must choose the right server system, generally use Linux or Windows 2000 Server or Windows Server 2003, this mainly depends on the configuration of your computer and the use of habits. In terms of networking, ADSL is definitely not a good idea. The network server you use to provide services to the outside world has a great demand for uplink bandwidth, while ADSL is an asymmetric link, and the uplink bandwidth is far less than the downlink bandwidth, and the limit of the uplink bandwidth of ADSL is only 1Mbit s, which is 128kbyte s s when converted into bytes, which is far from meeting the requirements of providing network services to the outside world.

The server's network firewall is special and cannot use the network firewall software of an ordinary home computer. The network firewall software of ordinary home computers will block all external network access to the machine, and the server is used to accept the access of the external network, so the software firewall for the server should be used, and the hardware firewall is best used if possible.

Generally speaking, it is divided into four main points.

1.Operating system security.

After installing the operating system, install an anti-virus software immediately, and upgrade the operating system patches, as well as anti-virus software viruses.

Upgrades to libraries and feature libraries. At this time, you should not wander around the server, there are many viruses and Trojans on the Internet. After the upgrade.

Hurry up and set some basic security permissions, including permissions for individual disk partitions and directories, and even down to related files.

security settings. The specific permission settings will not be discussed in detail here. Different operating systems, different application directions, and permission settings also.

It's different. Don't follow the online tutorial as it is, or you'll suffer.

2.The server is overloaded, it can be accessed, but it will appear that it will not be accessible after a while, this is the server is overloaded, and the server can't afford it after overloading, it is recommended that you.

Increase bandwidth and upgrade servers.

3.** Security with databases.

After writing the program, a friend uploads it directly to the server, sets it up, and doesn't care if the client can access it.

It's also the wrong thing to do. When writing ** programs, the syntax and judgment of the program must be rigorous, after the database is installed.

Be sure to keep up to date with the latest database patches and make some basic permission settings. **The program must be delivered to the server after it has been transmitted.

to set the permissions of the corresponding related directories. Although this will not guarantee the security of the entire server, it will at least greatly reduce the server.

The possibility of the server being compromised.

4.System problems, this problem can generally be hacked, today we will mainly talk about these three points, of course, there are many other reasons.

The operation of the server is best left to professional technicians to operate, otherwise once there is a problem, solve it by yourself, speed and quality.

There will still be some troubles in all aspects.

With rich IDC room management experience, professional technology and high-quality service, Zhongsheng Network is one of the most professional IDC providers in China.

Professionally provide you with server rental, server hosting, VPS, web hosting, and other online application services!

Penguin 854951957 Come on. After asking, points will be given.

Please find two usable **servers a, b (a can be your lan exit** or domestic 169 network address, b is a foreign **).

Unzip the ** file, double-click the exe file in it to install, and select Next. A window will pop up at the time of operation, explaining the function, and you can select "Off" to enter the setting interface after viewing.

1.In the "**" interface, fill in the "hostname or IP address" of "http** you need to pass through" the server A address and the port used, for example, port: 80. In the Options interface, select SSL (Connection) in Transfer Mode

Note that SSL here does not mean that the connection is encrypted! After setting up, be sure to use a level 2** that can encrypt both URLs and content to ensure security. At this time, you don't click the "Start" button, and continue with the following steps.

2.On the Port Mapping page, select External http** Server to change the three values.

Click sub-option (two clicks, but slower than double clicks).

2-1 local port (native).

-3128, you can change it, but generally use this default value, note that the browser ** should be consistent with this.

2-2 Remote host (b** server address or domain name).

and so on. Change to the second server address you want.

2-3 remote and spring split ports (the port of the second ** server you want to use).

-80, and so on. Instead, you want to use the port of the second server, like this.

3.Go back to the "**" interface and click the "Run" button to run it, so that httport is already running. The "Run" button becomes a "Stop" button and waits for you to click it again to end the httport.

4.Set up your browser. (It's the ** server that sets up IE, the method used to be).

In the IE menu, in the Internet Options Tools Connect select LAN **Address, fill in port 3128. If "Built-in SOCK4 Server" is selected in "Port Mapping", you can also use this in other software that supports SOCK4, **IP and port is::1080

5.Optional, in the "httport" option of the "system" interface, select "automatic minimized run", so that you will not see this setting screen again when you run httport in the future, it will only show a small icon in the lower right corner of the windows status bar.

If you want to abort or change the address, double-click the icon to set it.

6. After setting up the Internet, turn on IE, and browse the general homepage to see if it is normal. If not, please confirm that the steps are correct, and then confirm that the A, B** service is available.

I don't know much, but we technicians definitely do.

Let me answer! Let me introduce myself first, I am Wang Haibo, who works in the IDC industry, so I know more about this.

Problem 1: If the server is at home, if it is a local area network, then it doesn't matter.

A. But if you want to join the WAN and become a usable server, you must first have a fixed IP, your IP is definitely not fixed, and you will change an IP if you don't reconnect, although it can be solved by peanut shells, but it is also very unstable.

B. The network quality of home ASDL dial-up is difficult for the server of the general web page, not to mention the game, if a game card is very, it will be dropped, do you think someone will play?

c. There is generally only one line for household use, either telecommunications or Unicom. If you're on a telecom line, it's impossible for Unicom players to log in to your server and play games. (Just think about why the game is divided into a communication area and a telecom area).

So it is technically feasible to put it at home, but in fact, you don't even think about it.

Question 2: Regarding some features of SF, first of all, the bandwidth depends on the number of people in your **, including the configuration of the server is also determined according to the number of people. However, the number of ** people in general private servers is not too much, and the default 10M bandwidth of the computer room is enough to use.

If you do it in the whole country, it is recommended to use a double-line computer room.

Question 3: You buy a server by yourself and host it in the computer room, if you want to change the computer room in the middle, it is very troublesome, you have to pay a lot of postage and the logistics is very delayed, and the machine is also prone to problems. So it is recommended that you rent one.

Whether it is to change the configuration or change the computer room in the later stage, it is very easy to operate.

Question 4: **. Hosting** is generally a double-line computer room for 5000-7000 years, depending on the service and quality of the computer room, not the lower the better.

If you rent, it depends on the configuration, and the configuration is different.

If you have any questions, you can come and consult me! I've been in the IDC industry for many years!

Question 1: Theoretically speaking, the server can be placed at home, and the required bandwidth size should be determined by the number of people you need, but the speed and stability of home broadband are not very good, easy to disconnect, the game has high requirements for server stability, and it may not be able to operate normally if you put it at home. But now, most computer rooms are not allowed to do private servers.

Question 2: Hosting means that your server is placed in the IDC service provider's computer room, which provides fixed IP, location, bandwidth and 24-hour technical support.

Question 3: The server hosting cost is determined according to the specifications of your machine, the circuit and bandwidth of the computer room, the general server specification is 1U (1U = thickness, there are 2U and 4U machines, the computer room line has single line and double line, ** is also different, and the bandwidth, according to the required bandwidth, the cost is also different.

I hope it can help you, 59 Internet Xiaoning will answer for you.

Question 2: Yes, square computer room. But you're SF, and the regular computer room won't pick you up, so it's recommended that you put it at home.

Question 3: SF generally needs to find a special computer room to connect SF, and it is also a high-defense computer room, which is very expensive, 10,000 yuan to tens of thousands a year.

I don't really understand, but tell you you know.

1: Do discuz forum must need mysql database, as for whether to buy, to see if your own server is available, in fact, foreign web hosts generally have databases, no need to buy separately, only domestic will be sold separately from the web host and database, so you see if your cloud server has a database.

2: I don't know.

3: The so-called cloud is on the Internet, only the Internet can be used, your own local, you can use it without Internet access.

4: As for how to use, the domestic ones seem to be configured for you, and you can consult customer service directly.
