Installing an SSL certificate for a website is now a routine action, but if you have dozens of websites with SSL certificates installed at the same time, you may forget to renew a certain SSL certificate due to your own negligence. For some websites with very high application requirements, it will bring considerable losses.

Haomengyun Hdmidc is a VPS host run by Chinese people. It mainly sells VPS and servers. The computer rooms mainly include American DCS, Hong Kong, Guizhou Telecom, Tianjin, Beijing BGP, etc. Since it is on promotion, the current price of the host is very low. US CN2 VPS only costs 25 yuan/month.

A friend previously recommended the aaPanel panel to me on the special page of the server control panel list. This is an international version of the Pagoda Linux panel. It gives me the feeling that it is exactly the same as the Chinese version of the Pagoda Linux panel, except that it is changed to English. The interface is more suitable for foreigners to use, but other functions are the same.

iON VPS is a VPS hosting platform under the old website server hosting company Krypt. In 2019, it launched Telecom CN2, a two-way (two-way CN2 GT) Los Angeles VPS host. When it was first launched, the price was relatively cheap, only $5 a month. Everyone Very enthusiastic about buying. However, now although the configuration of VPS hosting has increased, the price has increased to US$10.

In the past, Alibaba Cloud's computer rooms in Hong Kong, Japan, Singapore and other places have always been under the impression that they are expensive and slow. After trying out the VPS host of the Alibaba Cloud international version of the Singapore computer room last time, I found that the VPS host of the CN2 line was not accessible to telecom users. It’s still quite fast, so I took advantage of the price reduction of Alibaba Cloud International Edition’s Hong Kong computer room to US$9/month and bought one.

When you see the $2.99 ​​price, I believe you should tell me who the VPS host I am talking about in this article is. Since it is extremely "popular" and everyone uses this VPS host for the same purpose, the result is that the official website cannot be opened. But the official seems to know about this, and in order to "save" the market, they launched another domain name, which is really a "good intention".

In the past, the first thing I thought of when using DNS was free DNS, because paying or not paying for DNS domain name resolution does not really seem that important compared to hosting and domain names. In reality, there are also many free DNSs, such as DNSPOD, Cloudxns, Alibaba Cloud Analysis, JD Cloud DNS, etc. You can find more in this article’s summary list of domestic and foreign free DNS domain name resolution services.

JD Cloud has launched a DNS domain name resolution service, but has been using DNSPOD due to habit issues. Recently, I have received feedback from many friends, prompting whether the mining site is inaccessible in certain areas. After ruling out the problem of the host line, it is speculated that it may be caused by the DNS resolution. After all, there are more or less problems when the server is placed abroad.

Free space, free VPS and free domain names are all free resources that are loved by everyone. Many novice friends should start building their own websites or blogs from free space. I have previously shared a place to apply for a free VPS host. Friends who like to play VPS can try: VirtualMaster and Dply.co.

Recently I found that the memory of the blog was always being "eaten" every now and then. After logging in to the backend, there would occasionally be lags. At first, I suspected that it was caused by insufficient Swap, so I added a few G of Swap to the VPS host and observed. After a while, I found that no matter how big the Swap was, it was slowly "eaten"!
