What You Will Do if You Use Nginx From Repository? Here is How To Change Nginx Server Header After Installation Which Reads Server: nginx.

Change Nginx Server Header After Installation : How it is possible?
Like awk, sed is very powerful tool. The command is simple, not very difficult :
|
1 |
sed -i 's/nginx\r/CHaNG\r/' `which nginx` |
nginx to CHaNG. If I want to change from CHaNG to nginx, then it will be :
|
1 |
sed -i 's/CHaNG\r/nginx\r/' `which nginx` |
Warning : BE CAREFUL ABOUT COPY-PASTING – the ‘ sign can change before s/ in the command and throw error! Copy-Paste in textedit or vim and check the punctuations first, then copy to ssh screen!

After running nginx -t you’ll get Segmentation fault (core dumped). It is quite scary looking. You need to the opposite command to make the dog’s tail straight :
|
1 |
sed -i 's/nginx-cloudflare\r/nginx\r/' `which nginx` |
