本地graph-node配置ens-subgraph

依赖

Rust (latest stable) – How to install Rust
PostgreSQL – PostgreSQL Downloads
IPFS – Installing IPFS

1.拉取代码

git clone https://github.com/ensdomains/ens-subgraph

git clone https://github.com/graphprotocol/graph-node //我使用这个版本报错

wget https://github.com/graphprotocol/graph-node/archive/refs/tags/v0.25.2.tar.gz
tar -zxvf v0.25.2.tar.gz

2.安装依赖项

安装 IPFS 初始化ipfs init，然后运行ipfs daemon。

安装PostgreSQLsudo apt-get install postgresql输入initdb -D .postgres，然后运行pg_ctl -D .postgres -l logfile start和createdb graph-node

以用户postgres进入postgresqlsudo -i -u postgres，输入 psql正常显示版本则正确。如报错可能需要重启postgresql，或者需要sudo apt-get install -y clang libpq-dev libssl-dev pkg-config。

psql 数据库名  --连接数据库
select rolname,rolpassword from pg_authid;--查看用户名密码
select usename,passwd from pg_shadow;--查看用户名密码
select version();	-- 查看版本
select current_database();--查看当前数据库
l					--查看所有数据库
dt					--查看表
password username	--修改密码
password           --设置密码。
?                  --查看psql命令列表。
c [database_name]  --连接其他数据库，切换数据库。
conninfo           --列出当前数据库和连接的信息。
d                  --列出当前数据库的所有表格。
d [table_name]     --列出某一张表格的结构。
du                 --列出所有用户。
e                  --打开文本编辑器。
help				--帮助
h                  --查看SQL命令的解释，比如h select。
q					--退出

sudo /etc/init.d/postgresql start   # 开启
sudo /etc/init.d/postgresql stop    # 关闭
sudo /etc/init.d/postgresql restart # 重启
此步骤为postgresql的安装、初始化、启用日志、创建数据库

如果使用Ubuntu，您可能需要安装其他软件包：sudo apt-get install -y clang libpq-dev libssl-dev pkg-config
cenos, yum install -y openssl-devel

3.生成契约ABI的类型

cd ens-subgraph
更改其中的subgraph.yaml

yarn

yarn codegen

4.编译启动graph-node

cd graph-node//cd graph-node-0.25.2 

cargo build

cargo run -p graph-node --release -- --postgres-url postgresql://postgres:postgres@localhost:5432/graph-node   --ethereum-rpc goerli:http://192.168.36.150:9545 --ipfs 127.0.0.1:5001

参数说明

postgresql 用户名为USERNAME和PASSWORD。密码可能是可选的。这取决于你的设置。上面的账号密码为postgres:postgres
rpc 为网络名称 : url
注意看graph-node的数据库和端口号是否正确

5.构建监听事件

创建
yarn create-local

添加监听
yarn deploy-local
