 vmvps-tutorial Today, I logged in to VPS of a managed website and found that there were various problems, including the inability to execute the Bash command related to file backup, which prompted a "read-only file system" error. After searching the Internet, most of the solutions were remount, but I failed after a try. Through experiments, the following methods can perfectly solve the problem:

1. View the current hard disk read/write status, and you will see that some hard disk attachment points will be ro (read-only), not rw (read+write)

 mount

2. Check the hard disk

 sudo fsck -y /

3. Restart the system, and the next boot will automatically run the hard disk detection. You need to wait for a while

 Micro demon tribe, novice tutorial Recently, I bought an Apple TV and installed some streaming media applications. Of course, for some well-known network reasons, I need to use the server to use it better. However, platforms such as Netflix, HBO and Disney+often have some special requirements for visitors' IP addresses, so not all VPS can unlock these platforms. How to know if your server can help you watch these TV programs. At this time, the help of one click script is the fastest.

Of course, it is better to directly search the previous purchase experience before buying, and then choose whether to buy the products of the merchant. In addition, not all machine rooms of the merchant support it, even different IP segments of the same machine room will have different results, so it is recommended to make preparations before purchase

Direct script

 bash <(curl -L -s check.unlock.media)

How to use it: use the above script and enter directly (or select according to your own needs). The results are as follows

VoceChat is a chat platform developed by Chinese people. It is lightweight (about 15M) and can be built on its own server (or local). It is a cross platform client. If necessary, the partners can install and run tests. The official provides two installation modes: Shell+Docker. If you want to experience quickly, you can choose Docker+Nginx (as shown below)

VoceChat installation method: Docker+Nginx mode

The following is excerpted from the official website: https://vocechat-doc.vercel.app/zh-cn/install/install-by-docker

① Run Vocechat under Docker (take the domain name chat.vmvps.com as an example)

 docker run -d --restart=always \ -p 3009:3000 \ --name vocechat-server \ -v ~/.vocechat-server/data:/home/vocechat-server/data \ privoce/vocechat-server:latest \ --network.frontend_ url " https://chat.vmvps.com "

② Modify Nginx configuration

The Nginx configuration file directory is generally in/etc/nginx/conf.d. Create a new Nginx configuration file chat.vmvps.com.conf, and configure the corresponding http request:

 server{ server_ name chat.vmvps.com; location / { proxy_ pass  http://127.0.0.1:3009 ; #  The port number here depends on the external port number of the Docker proxy_ redirect off; proxy_ set_ header        Host    $host; proxy_ set_ header        X-Real-IP       $remote_ addr; proxy_ set_ header        X-Forwarded-For $proxy_ add_ x_ forwarded_ for; proxy_ next_ upstream error timeout invalid_ header http_ 500 http_ 502 http_ 503 http_ 504; proxy_ max_ temp_ file_ size 0; #  Turn off the hard disk cache and increase the write speed #SSE related configuration proxy_ http_ version 1.1; proxy_ set_ header Connection ''; } }

③ Run Vocechat initialization configuration

 Nginx - t # Test whether Nginx configuration is correct Nginx - s reload # Overload Nginx configuration

Browser Access http://chat.vmvps.com (Note that the domain name DNS is resolved to your server in advance) The configuration is successful when you enter the initialization page.

④ Set the security certificate to implement HTTPS (take Cetrbot as an example)

1. Install Certbot (official website: https://certbot.eff.org/instructions Select the corresponding version to download)

2. Run Certbot to automatically read the configuration Nginx

 sudo certbot certonly --nginx

Nginx configuration will become

 server{ server_ name chat.vmvps.com; location / { proxy_ pass  http://127.0.0.1:3009 ; #  The port number here depends on the external port number of the Docker proxy_ redirect off; proxy_ set_ header        Host    $host; proxy_ set_ header        X-Real-IP       $remote_ addr; proxy_ set_ header        X-Forwarded-For $proxy_ add_ x_ forwarded_ for; proxy_ next_ upstream error timeout invalid_ header http_ 500 http_ 502 http_ 503 http_ 504; proxy_ max_ temp_ file_ size 0; #  Turn off the hard disk cache and increase the write speed #SSE related configuration proxy_ http_ version 1.1; proxy_ set_ header Connection ''; } listen 443 ssl; #  managed by Certbot ssl_ certificate /etc/letsencrypt/live/chat.vmvps.com/fullchain.pem; #  managed by Certbot ssl_ certificate_ key /etc/letsencrypt/live/chat.vmvps.com/privkey.pem; #  managed by Certbot include /etc/letsencrypt/options-ssl-nginx.conf; #  managed by Certbot ssl_ dhparam /etc/letsencrypt/ssl-dhparams.pem; #  managed by Certbot } server{ if ($host = chat.vmvps.com) { return 301 https://$host$request_ uri; } # managed by Certbot listen 80; server_ name chat.vmvps.com; return 404; #  managed by Certbot }

Overload Nginx configuration

 nginx -s reload

Browser Access http://chat.vmvps.com Automatically switch to https protocol

The price performance of this package is good, but according to the current feedback, this promotion The IO data of the hard disk is poor It can only be said that one cent is one cent of goods. It is recommended that you buy according to your needs. In addition The promotion money of this store does not support refunding , this requires additional attention.

Continued Previous Google originally turned off the free version of Gsuite, but recently, Google's instruction document redefined that if the free version is used for non-commercial personal purposes, it can continue to be used! It can be regarded as the news of great happiness. Of course, if you have upgraded to workspace, you can also return to the free version! The specific way is to log in to the management background (admin. google. com), click the question mark icon in the upper right corner to enter the Help Assistant, as shown in the figure below, and click!

Recently, the most troubling thing for Micro Magic is the fact that the free version of G Suite began to charge. As a person who experienced the free era of Google App, Micro Magic has several G suite for his own use, but recently Google has quietly modified its strategy (only written in the instruction document, but there is no extensive email notification through visual inspection). In short, it can be used for free until May 1, 2022, From May 1, it will automatically upgrade to the paid workspace. If you do not pay by July 1, you will not be able to use the core functions (including Gmail and Gdrive, and YouTube will not be affected). Because WeChat Magic has really been using G suite's domain name mailbox in daily life, it is really troublesome, so we collected some solutions. Of course, we finally chose to subscribe to the official workspace, and wrote the specific solution for your reference.

Free solution:

Domestic Alibaba Cloud and Netease Email , may be the first choice in China at present. Although Tencent's mailbox is also nominally free, it has a little threshold (although it can be fooled) to add a series of operations such as enterprise WeChat, which is still a bit disgusting. It is worth mentioning that WeChat Magic once used NetEase, and there was a problem that some foreign emails could not be received, which was also the reason for turning to Google at that time

Yandex and Mail.ru from abroad are two good choices. Two corporate mailboxes from Russia may be more familiar to Yandex. This company provides generous resources, but its disadvantages are obvious, that is, it is easier to enter the garbage bin

In addition, Zoho also provides free solutions. The free configuration of the previous years also supports IMAP, SMTP, and POP, but the current free solution is no longer supported. If charged, it is also very cheap. The domestic version is only 50 yuan/year, and the international version only costs 1 dollar per month. By the way, Zoho is divided into the international version and the domestic version in order to comply with relevant regulations in China, The domestic version is said to require real name authentication of ID cards, but the server speed should be faster. Micro Magic tried the international version of the mailbox, and the loading speed was a little touching

Other sources are Microsoft. If you have administrator privileges such as E3, E5 or A1, then it's good. You can bind your own domain name and enjoy Outlook. Of course, this kind of risk is that 99% of their origin is not officially guaranteed. To be honest, these subscriptions are trial programs, We all use some means and ways to obtain and maintain it, so we need to have some attitude of taking risks. In addition, although the home version of Office 365 can also be bound to a domain name, it only supports Godaddy's domain name through visual inspection. It has many limitations, more like email forwarding. It is not the same thing as the E3 and E5 mentioned above, so it is not recommended for everyone to use it, nor should you buy Office 365 for this purpose

Alternative solutions for charging:

  • FastMail (old brand)
  • Protonmail (mainly encryption, custom domain name is a little expensive)
  • RackSpace (some years ago, the positioning is not obvious)
  • MXRoute (good reputation in the community, not tried specifically)

Upgrade the official Google WorkSpace

Of course, if you upgrade to Google Workspace, you can also use the exchange rate to reduce certain costs. For example, we all know that Turkey is a low-cost paradise (you should have heard of Steam and Netflix in Turkey). Google Workspace in Turkey is also very cheap. Of course, A-3 District is also very cheap. In addition, Micro Devil found that in the process of upgrading, it also jumped out of the flexible package, as shown in the following figure, That is, until July, the money was free, and then the subscription for the new year was 70% off, which was very cheap.

Because I only use Gmail, I started the Starter Plan. Note that the Starter Plan does not have independent Gdrive, online documents and other functions. In addition to the mailbox capacity, it is also simple to configure compared with the free version of Gsuite (to switch to a more advanced package, click Add or upgrade subscription in the figure above)

Here is the key point, choose Turkey and Turkish lira currency

The following is the settlement. Find a Turkish address on the Internet and enter it. WeChat Magic has also used the domestic AE card. The subsequent deduction is still unclear.

 Dark Micro Devil Award Penguin Hut (qexw. com), as a VPS service provider for Chinese people, has also been introduced here by Weimo before. It features the VPS series for building a website in Hong Kong, which is cheap and fast. However, I received an email from this company a few days ago. Because of price increase and other reasons, I want to offline the related Hong Kong VPS business. On this matter, first of all, it was very sudden. WeChat Magic received the email on July 29, and the deadline for backup to users was 31, that is, two days. I just missed checking the mailbox, so the server lost contact. Of course, WeChat Magic didn't lose much. After all, it was just for fun and didn't store important data. However, in the follow-up, it seems that some people said that this company has lost contact completely. WeChat Magic tried to submit a TK the day before yesterday and didn't reply. Today, when we visited and logged in, the domain name jumped to billing.hosnetwork.com. It seems that this company is making a big business adjustment, which may be a sale or a complete transformation. In short, we should do a good job of data backup to avoid heavy losses.

The original message is as follows,

 We are very sorry to inform you. Due to the rise in bandwidth prices in Hong Kong and related operational barriers, our company has discussed. Therefore, products below the production line. All products of Hong Kong Phase I. All products of Hong Kong Phase II. All products of Hong Kong Phase IV. The CN2 bandwidth capacity is insufficient. All products except 216.83 (old station) in the third phase of Hong Kong Station Construction are offline. Note: Please make backup before 12:00 on July 31, 2021 for customers in the above regions (only HE line backup is supported in case of timeout). Only Hong Kong Phase V, Hong Kong Phase VI and Hong Kong Phase VII network products will be retained. And continue to provide you with NTT+HE+HKIX line services. Solution: Hong Kong Phase III customers can ask whether they support replacing to the 216.83 section (old station) area with a work order. The offline product VPS is returned to Alipay by default. The offline product VPS can be accelerated by queuing up in the General Affairs Department of the work order. The offline product pushVPS needs the work order general affairs department to sort it out and refund it to the actual owner Alipay according to the actual value. remarks: Reason for offline: 1. The CMI supplier learned that its CMI Transit has limited its speed to 5% in the mainland. Upgrade to CMNET (unit price: 20 $1Mbps).
