Solana Anchor framework: Can't connect to localhost and therefor not deply to it

Question

Anchor deploy Deploying workspace: http://localhost:8899 Upgrade authority: /home/tomcatzy/.config/solana/id.json Deploying program "basic-1"... Program path: /home/tomcatzy/projects/anchor/examples/tutorial/basic-1/target/deploy/basic_1.so... Error: RPC request error: cluster version query failed: error sending request for url (http://localhost:8899/): error trying to connect: tcp connect error: Connection refused (os error 111) There was a problem deploying: Output { status: ExitStatus(unix_wait_status(256)), stdout: "", stderr: "" }.

solana config set --url http://localhost:8899 (Is this enough to start the localhost ?) solana-keygen new solana-test-validator

It seems strange that after a succesful anchor build that i can't do a anchor deploy with the solana command lines ran above. If by any means 'need' to run a - npm init - then where to do it ?

solana config set --url http://localhost:8899 (Is this enough to start the localhost ?) solana-keygen new solana-test-validator

I tried the above and got generated a keypair: keyname_1-keypair.json. The build went succesful but the deploy not !

I'm wondering why not ?

Hopefully some can guide me what to get it succed...

Answer 1

You can deploy on-chain programs with the Solana tools. To deploy a program, you will need the location of the program's shared object. It will return when you run anchor build in the command line. Run solana program deploy <PROGRAM_FILEPATH>. Successful deployment will return the program id of your program.

By following the Solana docs and doing this

sudo $(command -v solana-sys-tuner) --user $(whoami) > sys-tuner.log 2>&1 &            

https://docs.solana.com/running-validator/validator-start#system-tuning

The test-ledger folder is done and a sys-tuner.log file is created but it's 0 bytes...

Then i run the solana-test-validator in a separate terminal and the other solana config commands in another termianl then i get the following results ->

Answer 3

In a separate window / terminal, you need to run solana-test-validator so that the tools can talk to your local network. The error you're seeing on deployment is due to an error on connecting to that network.
