I used Alibaba Cloud to purchase a pay-as-you-go server, the system is: centos 7, first, install the necessary package, the command is as follows:
Review:
Download nginx-1.20.1
Download using the wget command, as follows:
Unzip nginx-1.20.1
The command is as follows:
Download Nginx-image-filter-watermark
nginx-image-filter-watermark patches Nginx with watermarking. http_image_filter_module-based patches,It can convert images in JPEG, GIF, PNG, and WebP formats。
Should work fine on nginx >= 1.11.6. GitHub address:The hyperlink login is visible.
