安裝rust
curl https://sh.rustup.rs -sSf | sh安裝parity
git clone https://github.com/paritytech/parity-ethereum
cd parity-ethereum
git checkout stable //只安裝stable版本
cargo build --release --features final
或直接下載 binary :
https://github.com/paritytech/parity-ethereum/releases
缺少套件
- libudev.h
yum install systemd-devel- cmake3:
下載cmak3 source (https://cmake.org/)
./bootstrap --prefix=/usr/local
make
make install
執行
./parity --jsonrpc-interface=w.x.y.z --jsonrpc-apis=eth,web3,personal,net,traces --jsonrpc-cors=all --chain=ropsten --jsonrpc-threads=1 --tracing=oninterface 表示要綁在哪一張網卡上
參數說明
- --jsonrpc-interface 綁定rpc service的IP
- --jsonrpc-apis 5 RPC支援的API
- --jsonrpc-cors 允許CORS的網域
- --chain 使用的ether網路名稱
- --jsonrpc-threads RPC服務耗用CPU的資源
- --tracing=on 開啟trace模式
- --geth geth相容模式，讓RCP的指令可以跟geth相容一點點
- --warp 使用snapshot方式同步最近的資料，之後有空的時候會慢慢同步前面的資料
config
- parity也可以使用設定檔，設定檔位址在~/.local/share/io.parity.ethereum/config.toml

問題排除
- 錯誤訊息 : TraceDB resync
required
修改~/.local/share/io.parity.ethereum/chains/test/user_defaults，把tracing改為true - 當啟動tracing模式的時候將無法使用warp sync
RPC 執行範例
- Command
