Before buying a VPS host, I usually check the reviews of other people using the VPS host. In particular, the line of the VPS host is what I am most concerned about. Because there are many foreign VPS hosting providers, but there are only a few computer rooms with fast access speeds from China. A VPS with poor lines and slow speed is not suitable for building a Chinese website.

Vultr is a foreign VPS hosting service provider. In China, Vultr is often compared with Linode and DigitalOcean, two cloud hosting providers, which shows the popularity of Vultr in China. Vultr is a rising star, but it is developing very quickly. It has 14 data centers around the world including Tokyo, Japan, Los Angeles, Seattle, London, England, and Germany. Generally speaking, Vultr is still far behind Linode and DigitalOcean VPS, but Vultr’s advantage lies in its low price.

Linode is a very famous VPS hosting provider in the United States. It was established in 2003 and provides VPS hosting. It has been focusing on providing servers running Linux for more than ten years. In the early years, Linode VPS was sold at a very high price. Similar monthly VPS product Linode sold for US$20, but many people still like it because Linode is stable. Linode changed its virtualization technology from Xen to KVM in June 2015, and the price has continued to drop since then, until the current price of 1GB of memory and 1TB of traffic is only $5.

ISPConfig 3 is a very excellent foreign VPS host control panel. It is free and open source and has been continuously developed for several years. Currently, ISPConfig 3 can basically be installed on all major Linux operating systems and supports one-click installation, including Apache2 and nginx, Postfix, Dovecot, PureFTPD, Bind, PowerDNS, MySQL, etc.

Since the blog host is located abroad, although the classic CN2 GIA is used, the speed is much faster than that of a VPS host placed in an ordinary American computer room. However, writing articles requires inserting a large number of pictures, and WordPress has installed many Plug-ins (see: Summary of Wordpress plug-ins for digging websites) cause the browser to make a very large number of requests to access the page.

HostDare is a personal VPS host provider in the United States. A friend introduced me to HostDare's CN2 VPS host in a summary of access to CN2 line VPS host providers and computer rooms. HostDare seems to prefer to provide VPS to Chinese people, so the official websites of many routes are marked as Asia-optimized. In terms of price, HostDare's VPS is relatively cheap. The cheapest VPS host with Openvz architecture is US$12.5 per year (memory is 512MB), and the VPS host with KVM architecture with 756MB of memory costs US$2.99 ​​per month. If it's on sale, the price may be cheaper.

SSL certificates have basically become the "standard" for building websites now. Whether it is the attitude of search engines towards HTTPS encryption or users' awareness of HTTPS links, SSL's status in the current Internet has been greatly improved, so Friends who haven’t configured an SSL certificate for their website yet, don’t hesitate to get Https.

If we find that our VPS server is abnormal, generally we can analyze it from the server logs to see if there is an IP source that does not follow the "rules". For example, we can use server log analysis tools: ngxtop and GoAccess to analyze the IP source, number of connections, error requests, browsers, traffic bandwidth, etc. in the statistical logs.

Many friends may not have heard of FFmpeg, but you must have used one of these software: Baofeng Yingyin, QQ Yingyin, KMP, GOM Player, PotPlayer (2010), KMPlayer. FFmpeg is open source software, and software that uses FFmpeg in accordance with the agreement must also be open source. However, these audio and video software do not comply with the agreement, so they were put on FFmpeg's "blacklist".

Gcore VPS is a VPS hosting provider from Russia, but Gcore VPS has computer rooms all over the world, mainly in Moscow and Khabarovsk in Russia, Seoul in South Korea, Tokyo in Japan, Chicago and Miami in the United States, Sydney in Australia, Amsterdam in the Netherlands, Sao Paulo in Brazil, etc. , and supports Alipay payment. For Chinese people, the most popular computer rooms of Gcore VPS are Moscow and Khabarovsk in Russia. The access speed of these two computer rooms in the country is very fast, especially the Khabarovsk computer room.
