Recently, the blockade of V2ray has become more and more strict, and it has become more and more troublesome to surf the Internet. I was forced to learn the installation and configuration of Trojan.

# introduce

Trojan can disguise scientific Internet traffic as HTTPS web browsing. Compared with other tools such as Shadowsocks/SSR/V2ray, Trojan has a better camouflage effect and is less likely to be blocked because it has a real web page as a cover. From this point of view, Trojan is very similar to V2ray's WS+TLS mode, and the effect of using the two is also very close.

# DNS

Because Trojan needs to use https to disguise the website, it needs to resolve a domain name to the IP address of the VPS. This part of the operation depends on your DNS provider, and the specific operation can be set by yourself.

# Install

Use the one-click installation script to install Trojan, and fill in the domain name, port and password you just added to resolve the domain name.

curl -O https://raw.githubusercontent.com/xxxbrian/trojan.sh/main/trojan.sh && chmod +x trojan.sh && ./trojan.sh

# Enable BBR

After the above steps are completed, the Trojan server has been built and can be used directly. However, some additional measures can be taken to further optimize Trojan’s connection speed and improve user experience. Trojan uses TCP traffic, you can install the TCP acceleration tool BBR for the server to further optimize the network. CentOS:

wget --no-check-certificate https://raw.githubusercontent.com/tcp-nanqinlang/general/master/General/CentOS/bash/tcp_nanqinlang-1.3.2.sh
bash tcp_nanqinlang-1.3.2.sh

Debian:

wget --no-check-certificate https://github.com/tcp-nanqinlang/general/releases/download/3.4.2.1/tcp_nanqinlang-fool-1.3.0.sh
bash tcp_nanqinlang-fool-1.3.0.sh

After selecting 1 to install the kernel, a restart is required, and after restarting, run the script and select 2 to enable the algorithm.
