First of all, let's solve the most frequent noise problem in the last comment: Here we use the highest score in the Xiaomi app store to complete the test. At first boot, the noise is quite large, about 60 decibels (the phone on the machine), but after 25 seconds it drops below 55 decibels, about 50 seconds stabilizes around 45 decibels, stable after a minute At 40 decibels, this is the result of testing directly on the machine; if you close the door (without soundproofing material, on a wooden board, in normal operation), almost a meter or so has almost no sound, the noise is about 25 decibels This is already negligible. Therefore, noise is not a problem at all. Video outside this cell phone opened up to 80%-90% of the sound and the actual sound is almost the same. The next issue is power consumption. When the value-friends asked this question, I ran to the nearby electronics market to buy a power meter. As a result, I asked for no one to sell for a long time. Finally bought on a treasure. The overall power consumption is around 130W, of course, this is in the case of a dual CPU. This server can also run on a single CPU. When the single CPU is running, the power consumption is about 95W. The price of dual-way operation is 1.68 yuan per day, and the price of one-way CPU is about 1 yuan per day. Listening is quite expensive, but you get an additional server. The landlord usually uses a lot of windows virtual machines for learning. They can all be run on it. Video rendering and transcoding can also be run on the server. I can also use a mc server to play games with my friends. I still have a full-house control system that can control most of the appliances in my home (this cloud server, which was originally built on Alibaba Cloud, is now configured directly on the server. This server is deployed. About this later). After all, everyone's usefulness is different (do not need to ignore it directly), we can also run on low-power platforms (GEN8 or other DIY PC) if the idle power is high, after all, this series of articles applies to all computers that can install windows. . Symbolic previous link In a statement, the landlord is a professional in automation, not a student in the computer science department. Being a NAS is just out of interest. There will be many unprofessional places. Please also correct me. Second, some people say why do not use larger hard drives, use a bunch of small solid, in fact, these solid state is the main machine retired down, the capacity is relatively small (100G is not to), but the long life (after all, intel) put the main force There is no big use on it, I think it is better to reduce the reading and writing pressure of the mechanical hard disk. There are also a few pieces of machinery are also the main machine on the former, because too noisy, so threw it to the server. Some people say that summer can not be used, the landlord just bought, have not encountered such hot weather, so I still can not say, wait until next summer will sum up this project plus Tucao. Closer to home, from the beginning of this article, our content does not involve hardware, the same can be used on an ordinary PC (GEN8, ordinary PC can use anything), the system can also be replaced win10 (reduced storage space, configuration is simpler, delete Some of the features, but there are alternatives, little effect, no difference, this article we mainly install and configure the soft route. The mirror of the soft route can be downloaded from the official website. Here is the link. The ISO image of X86 is recommended here. X64 needs at least 4G of memory to install, and normal use can't use so much (except for corporate internet cafes). Before you install and configure soft routes, look at the home network's unique network topology. As it is a time-honored house, the pre-embedded network cables are all five types of lines and cannot use Gigabit. There is no way but to take the open line. This requires that the lines must be small enough to be hidden. First explain the structure, (do not look at the above model, change it) Telecom light cat directly out of the "router" LAN port (where the router is used when the switch + wireless AP, WAN port does not insert anything), LAN port There is also a line to switch (Jingdong cheapest gigabit switch) switch to the host, server and other AP. First look carefully at the topology diagram, some people will find why the external network of telecommunications (light cat) can be directly inserted into the router's LAN port can also be used, this is equivalent to each computer is connected with two network cables, one is a LAN, there is a Root to light cat, so no matter where the router is installed, it means that when the internal network transmits large files, the network speed will drop a little. This problem can be solved by using port aggregation or directly on the 10Gb network. However, due to the fact that the house is old enough, it will not be tortuous here. Before installing soft routing, it is recommended that everyone change the IP address of the computer and NAS to fixed IP, all on the same network segment. Open Server Management, enter Hyper-V Manager Create a virtual switch Random name, connection type set to external network Create a new virtual machine The name is arbitrary and can be identified. Algebra is the first generation. 1G memory enough The network is connected to the external switch that you just created Create a virtual hard disk, random name and location, the size of about 1-2g, if you want to record the client's access record can be set a little larger. Choose to install the operating system from the CD, select the image file, here we choose the file we just downloaded from the official website. After the completion of our soft route only one network card, we also need to add a network card. Right click on the soft route you just created The route needs two network ports, one to access the public network and one to access the intranet. There is only one here, so we add another network card. Select Add Hardware -> Network Adapters -> Add -> OK So we have two network cards, you can start the machine, right click, and then click the start button. Follow the prompts to install the system to the disk, after the installation is complete, shut down, shut down, enter the settings, find the DVD drive, set to none. Otherwise, the reboot will still enter the interface of the installation system. Remove the boot from the ISO. According to the given WEB management address, accessing the address in the browser will be able to enter the management interface. Both the account and password are admin. If you successfully enter the management interface, please skip this paragraph If you cannot enter the management interface, check if your own IP is in the same network segment (address, mask) as the soft route. If the mask is 255.255.255.0, then 192.168.1.1-192.168.1.255 is in the same network segment. The mask is 255.255.0.0, and 192.168.1.1-192.168.255.255 is in the same network segment. If not in a network segment, we can modify or modify the router IP, as long as the security console prompts for operation, enter 2 in the soft routing console to modify the LAN address, and then save according to the prompts. In addition to modifying the computer IP, we can also modify the computer's IP: windows lower right corner -> Network -> right click to open the network and internet settings Change adapter options Right click -> Properties Find IPv4->Double-click Modified to the same network segment as the soft route After the setup is complete, we should be able to enter the soft route. At this time we cannot get on the network and we need to configure the router to access the network. First you need to bind your network card. Go to Network Settings -> Extranet Settings to bind a free network card. Fill in the account number and password given by the operator and select the bandwidth. It is recommended to delete the DNS automatically (from time to time, it will explode) and save the connection. Configure dns to fill in the DNS address, here we use Ali DNS (223.5.5.5 223.6.6.6), start plus service, using cache mode. Equivalent to host. The following DNS reverse proxy is the key point. The automatic switchover of the group's extranet/intranet address depends on the DNS reverse proxy. For example, we first apply for a domain name, here abc.cc as an example, Synology's intranet address is 192.168.10.8 (see the actual address, need a static address or DHCP binding, said later), we put Synology intranet IP Mapped to abc.cc this domain name, so that when we visit abc.cc in the internal network, the actual access address is 192.168.10.8, so that you do not have to go around the public network, the network speed will be much faster (concrete next speak). DNS reverse proxy has many magical uses. For example, if you don't want to see a website, for example abc.com, we just need to map abc.com to a non-existent IP so that it cannot be accessed (intranet only). . Of course, this also simplifies intranet access. I mapped the router's IP address to ak.cc, so that I could access the router by accessing ak.cc on the internal network. DHCP settings, in fact, I do not recommend the use of dynamic address of the service device, so that each visit must first confirm the IP address. Here I recommend that the service device use fixed IP or static allocation so that it can obtain a constant IP address. Then set up the port mapping, to access the internal network equipment from the public network, this setting is essential (except for peanut shells) If you want to save trouble, set the DMZ directly, throw the entire server to the public network, but this security is not high. Another method is port mapping, mapping out the port, for example: to use Remote Desktop Connection Server (192.168.10.7, 3389 port), the internal network address needs to fill in 192.168.10.7, the internal port to fill 3389, (every service There are fixed ports ftp21, http80, https 443, Synology Management 5000 and so on, it is not clear that Baidu) external network port to fill in, if not the default port, as long as the time to access the port number on the line. There are many fun functions in the soft route, such as replacing URLs, replacing keywords, replacing parameters, and recording behaviors, waiting for everyone to explore. Let's talk about this first, followed by DDNS. As we all know, home broadband has no fixed IP, and some do not even have public IP. We need to have a public network IP to access internal network devices from the public network. Check whether it is a public network IP is very simple, Baidu search IP, out of the address and your router to obtain the address is not the same, is the intranet address, Jiangsu Telecom user router if the IP is 100.XX.XX.XX, congratulations Do not check, this is the intranet IP. Obtaining a public IP network is particularly simple. I have a telephone call for telecommunications (I use Jiangsu Telecom). I need a public network IP address (I said these six words). The customer service has also returned two words: Wait a minute. If you are using broadband in the community, you can ask the administrator whether you can open a DMZ or map several important ports. (If you don't use public network IP, please use peanut husk or ngrok.) After restarting the router, you will find that it is no longer the internal network IP. Happy, but the IP will always change every 24 to 48 hours or restart. The router will change, and solving this problem is also very simple. Apply for a domain name and use the API interface provided by the domain name service provider to modify it directly. Here we apply for a Wan Wang (Aliyun) domain name here is a link. Some special offers are only two yuan a year. After the purchase is completed, enter the console (upper right corner) and enter the domain name option. Check the domain name you just purchased. Click Manage, Add Parsing Fill in as required, the record type can only fill A, DDNS only supports A record. The host records us to fill in @, look at the help specifically, fill in the record value casually, will automatically revise when time arrives. After you finish, check your own id and key. Write down ID and Key Some time ago when I was visiting GitHub, I found that someone had written a section of Alibaba Cloud's DDNS code and run an IP check once. Go to GitHub to download the source code, here is the link, but the downloaded file is a python file. Requires python interpreter to run. Fill in the ddns.conf file with the ID and Key you just entered. Fill in the ID and Key, domain name, and record (must be the same as the one you just created, otherwise you will get an error). By running this script once, you can check whether the current IP has changed, and if you change the IP that was uploaded and changed. However, the python script is a bit annoying to run on the win. Click to view how to run the python program (started in 46 seconds) The EXE on Windows is more common. To use it conveniently, use PyInstaller to encapsulate it into an EXE so that everyone can use it. This realizes ddns. (I just learned about Python for a week or so and watched the tutorial completely. The gods please move to GitHub). Here is the exe download address ELUX Legend 3500 Puff Bar pen is compact slim in design, light, & portable, and easy to carry in pockets and bags, which means it goes where you go.
