1. Cause
Sometimes there are many projects rely on the server, some may depend, for whatever reason can only run on linux environment, or too many packages depend, in short, is not convenient locally run project, it can only be debugged remotely.
2. Install delve
This command is installed on a server running delve
go get -u github.com/go-delve/delve/cmd/dlv
3. Compile the project
Remember to add -gcflags='all=-N -l
here assume that the compiler is main.go
go build -gcflags="all=-N -l" ./main.go
4. Start the server program debug mode
One way: intrusive debugging code
It is in the process of commissioning the
assumption that the program mainis already running in the
first ps -aux | grep mainview of the main program PIDand then start debugging invasion
dlv attach $PID --headless --api-version=2 --log --listen=:1234
Second way: Start the debugging process
dlv --listen=:1234 --headless=true --api-version=2 --accept-multiclient exec ./main
5.Goland debugging
下面这几步很重要！！！！
Current local projects designated GOPATH
Add a remote debugging strategies
Host , is that you can Unicom's IP address or machine name of a remote server; Port , is just dlv specified when the debug start listening port
Editor top right, select the name of the policy remote debugging, is named after the previous step, and then click the green bug
The successful commissioning
6. End Debugging
After the end of the local debugging, if the program wants to suspend the server, CTRL + C is not able to terminate the program, so it is necessary to force killout the service
ps -aux | grep dlv
ps -aux | grep main
to return
root 27089 8.0 2.1 297472 39812 pts/1 Sl 12:34 0:00 dlv --listen=:8888 --headless=true --api-version=2 --accept-multiclient exec ./main
root 3157 0.0 0.4 148296 8496 pts/1 Sl 11:59 0:00 ./main
Then kill off separately
7. Finally, note
After completion of the code to change the local remote server must recompile! ! ! Otherwise debugging time will be the case
