- Attention 注意
The unexpected thing showing previous command is underlying go-redis v3 client library will try connect internal Redis address. and spend a few time to exit.
The case shows program must communicate with Redis and Sentinel cluster, thus should configured with same subnet, or with DNAT to forward data packages to backend
After go build or go install, copy secret, static, tmpl sub-dirs in where executable is located
- secret dir, hold a authentication file 该子目录包含密码文件
- static dir, simple content for index.html 该子目录为主页的静态内容
- tmpl dir, Golang http/template format 该子目录是模板文件
