Solana合约部署及调用

针对 Solana helloworld测试合约 进行编译、部署及调用。
1）安装Solana tool suite：

sh -c "$(curl -sSfL https://release.solana.com/v1.7.10/install)"

设置指向testnet：

$ solana config set --url https://api.testnet.solana.com
// 确认：
$ solana config get
Config File: /Users/xxx/.config/solana/cli/config.yml
RPC URL: https://api.testnet.solana.com 
WebSocket URL: wss://api.testnet.solana.com/ (computed)
Keypair Path: /Users/xxx/.config/solana/id.json 
Commitment: confirmed 

2）编译合约：

$ npm install
$ npm run build:program-rust

> [email protected] build:program-rust /Users/xxx/zyd/example-helloworld
> cargo build-bpf --manifest-path=./src/program-rust/Cargo.toml --bpf-out-dir=dist/program

BPF SDK: /Users/xxx/.local/share/solana/install/releases/1.7.10/solana-release/bin/sdk/bpf
Running: rustup toolchain list -v
Running: rustup toolchain link bpf /Users/xxx/.local/share/solana/install/releases/1.7.10/solana-release/bin/sdk/bpf/dependencies/bpf-tools/rust
Running: cargo +bpf build --target bpfel-unknown-unknown --release
...........

3）部署合约：【$ solana airdrop 1 获取测试token】

$ solana program deploy  dist/program/helloworld.so
=============================================================================
Recover the intermediate account's ephemeral keypair file with
`solana-keygen recover` and the following 12-word seed phrase:
=============================================================================
embark glimpse hidden nasty unfold donor miss relax dawn suggest bargain nest
=============================================================================
To resume a deploy, pass the recovered keypair as
the [PROGRAM_ADDRESS_SIGNER] argument to `solana deploy` or
as the [BUFFER_SIGNER] to `solana program deploy` or `solana write-buffer'.
Or to recover the account's lamports, pass it as the
[BUFFER_ACCOUNT_ADDRESS] argument to `solana program close`.
=============================================================================
Error: Account CiXLP94T6QBrEdevnJrGEDcN3iRaEWMKm7bv76ogpsZm has insufficient funds for spend (0.4265436 SOL) + fee (0.001355 SOL)

$ solana airdrop 1
Requesting airdrop of 1 SOL

$ solana balance
2.71772184 SOL

部署完合约，默认该合约地址的balance不为0 SOL：【直接就从创建者账户中划了2年的租金到合约账号。】
