关于智能合约:The-Graph-应用开发-mac10certos8环境配置

本文从团队开发 the Graph 利用 subgraph 的场景为背景，介绍其环境的搭建：线下开发的机器比较复杂就以 mac 机器为例一步一步配置解说，线上环境属于比拟洁净但辅助软件欠缺，须要从头部署，读者能够按需浏览。

The Graph 开发环境搭建

Ganache 部署

除了本地部署官网文档，还有这篇介绍本地部署的文档

NPM/Yarn 全局装置 truffle ganache-cli

$ npm install -g truffle ganache-cli
   or 
$ yarn global add truffle ganache-cli

ganache-cli 启动

$ ganache-cli -h 0.0.0.0

Ganache CLI v6.12.2 (ganache-core: 2.13.2)

注：带参数的启动能够再现大部分历史环境
例如：ganache-cli -h 0.0.0.0 -v /db -b 6 -a 8 -e 1000 -d expect chair toe trade spider wedding say item scare fog shrimp garlic
关上存在库，设置主动挖矿工夫 6，设置 8 个 1000gas 账号，导入现有私钥，（-d，能够是里面，也可用 - m 产生）

拉 graph-node（本级简单的环境历程）

下载 https://download.docker.com/m…，装置放入 APP 中，运行并输出明码，命令行可用。

所有看起十分失常，然而后续装置可能会产生各种问题，因你的本机软硬件环境而异，但都须要平常心对之。

$ brew install jq
$ docker -v

brew install 装置更新出师不利，填坑见 brew upgrade 装置报错 解决 brew upgrade mac 更新组件遗留问题。
Docker version 20.10.5, build 55c4c88 还 ok。
拉 graph-node 节点

$ git clone https://github.com/graphprotocol/graph-node/

此处 git 等常见人力不可达地区资源坑见 代理与镜像坑 有时候重复多试试就过来了，过来了就保重劳动成果，备份一些资源，未来有不可抗力时能够把这些文件 复制 / 粘贴（或者间接利用你共事的洁净环境获取本地文件，回头再解决你的环境问题）

配置启动 the Graph

$ cd graph-node/docker
$ ./setup.sh #write the host IP address into docker-compose.yml.
$ docker-compose up #Start a local Graph Node that will connect to Ganache on your host

graph-node_1 | Jun 22 11:13:56.399 INFO Starting metrics server at: http://localhost:8040, component: MetricsServer

启动 docker-compose up

时报错是因为拜访 host IP 导致 解决

敞开节点 docker-compose down -v;

docker-compose down -v;
if [-d”data”] thenecho”Found old data for the graph node – deleting it”; # we need to sudo this to remove system locked filessudorm-rf data/;
fi

客户端 graphprotocol/graph-cli 装置

$ npm install -g @graphprotocol/graph-cli
$ graph init --from-example moluoping/mark-cion 
 #graph init --from-example <GITHUB_USERNAME>/<SUBGRAPH_NAME> [<DIRECTORY>]

产生的 yarn 性能 lock 文件锁住了依赖包的版本，也锁住了源 url 不能用镜像
解决：备份 lock，应用 npm 拉下所有包（淘宝镜像不全，应用官网 http://registry.npmjs.org/）
（比拟版本依赖）资源坑见 代理与镜像坑

下面是通过例子生产合约和 subgraph

还能够间接从容器中合约向导生成 subgraph 工程：

$ graph init --from-contract 0x1e1215caD01aD7192832e0DACfA930Caf0132b43  --network mainnet --abi markdemo4.json moluoping/markdemo4

编译 & 部署合约

$ truffle compile

监听合约通过合约 Id，配置

$ sed -i -e 's/0x2E645469f354BB4F5c8a05B3b30A929361cf77eC/0x71e11bC372507d508E05f65c096d32F1eF62Cdf7/g'     subgraph.yaml

此处犯一低级谬误，第二个合约才是真正无效的，但第二指令为达到成果
sed -i -e ‘s/0x2E645469f354BB4F5c8a05B3b30A929361cf77eC/0x0A994866b43562c083C81E1B4AD6145214f56c56/g’ subgraph.yaml
应该改为
sed -i -e ‘s/0x71e11bC372507d508E05f65c096d32F1eF62Cdf7/0x0A994866b43562c083C81E1B4AD6145214f56c56/g’ subgraph.yaml

因为第一次命令曾经替换了文本

编译、创立 subgarph，公布 the graph App

下载依赖包，编译

$ yarn && yarn codegen

改成 $npm install
$yarn codegen
该计划长期获得依赖实现后续工作，ok 后解决环境问题见 代理与镜像坑

8001 端口与 Vray http 代理端口抵触，批改 Vray http 代理端口为 8701，顺便把 git clone 和 yarn 下载的代理问题解决

代理与镜像坑点

特地留神 8001 端口与 Vray http 代理端口抵触

批改 Vray http 代理端口为 8701，顺便把 git clone 和 yarn 下载的代理问题解决

特地留神代理，代理，代理

咱们不在代理，就在镜像的路上，有时候 git 和 yarn 还是会报同步错，这时候能够重复如下操作

git config --global http.proxy socks5://127.0.0.1:1080 
git config --global https.proxy socks5://127.0.0.1:1080

git config --global https.proxy http://127.0.0.1:1080 
git config --global https.proxy https://127.0.0.1:1080

git config --global --unset http.proxy 
git config --global --unset https.proxy

开关 / 开关代理

brew upgrade 装置报错问题解决替换 homebrew-bottles

$ brew upgrade
 或者
$ 任何须要更新的命令
所以必须解决

计划一：替换文件
找到 /Users/gaoxiaoqing/Library/Caches/Homebrew/downloads/ 发现有 66ff350c21fce7c264e33e3cff6f4995978ac401d5e5047c0ee8dd17e3493a53–m4-1.4.18.mojave.bottle.1.tar.gz，改名。ok，我预计是有两个或两个版本用到这个，前面一个就缓存不生成了，然而忙过当前还是睡不着啊，有了第二种解决方案。

计划二：替换 homebrew-bottles

echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile
 
source ~/.bash_profile

brew 包含四块

如果用到也同样可改镜像

$ git -C "$(brew --repo)" remote set-url origin https://mirrors.ustc.edu.cn/brew.git
$ git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git
$ git -C "$(brew --repo homebrew/cask)" remote set-url origin https://mirrors.ustc.edu.cn/homebrew-cask.git

配置文件脚本主动替换坑

the Graph 线上服务器 & certos8 装置

装置线上服务器 docker & 启动

# sudo yum install -y yum-utils   device-mapper-persistent-data   lvm2
# sudo yum-config-manager     --add-repo     http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# sudo yum install docker-ce docker-ce-cli containerd.io
# yum list docker-ce --showduplicates | sort -r

# sudo yum install docker-ce-20.10.7-3.el8 docker-ce-cli-20.10.7-3.el8 containerd.io
# sudo systemctl start docker

拉下节点 graph-node & 配置启动

# git clone https://github.com/graphprotocol/graph-node/

装置 docker-compose

# yum -y install epel-release
# yum install python3-pip）

yum install python-pip（certos7）

# pip3 install --upgrade pip
# pip install docker-compose

pip3 install –upgrade pip（certos7）
若应用 pip install docker-compose 装置失败，则应用上面一条命令试试 #pip –default-timeout=200 install -U docker-compose

装置 install ‘jq’

# yum install jq

运行环境设置，重点关注 IP 地址 copy

# cd graph-node/docker
./setup.sh 

write the host IP address into docker-compose.yml. 如果 ip 不是你主机 ip，手动批改

docker: read tcp 192.168.7.235:36512->54.230.212.9:443: read: connection reset by peer.

应用下一节阿里云镜像减速解决

阿里云镜像减速

https://help.aliyun.com/docum…

应用 Docker 时须要首先下载一个官网镜像，例如mysql、wordpress。然而因为网络起因，下载一个 Docker 官网镜像可能会须要很长的工夫，甚至下载失败。为此，阿里云容器镜像服务 ACR 提供了官网的镜像站点，从而减速官网镜像的下载。镜像加速器是面向集体开发者的服务，仅限额反对集体开发场景，不容许有再次封装或商业用途。

# sudo mkdir -p /etc/docker
# sudo tee /etc/docker/daemon.json <<-'EOF'
{"registry-mirrors": ["https://de43k63h.mirror.aliyuncs.com"]
}
EOF
# sudo systemctl daemon-reload
# sudo systemctl restart docker

https://de43k63h.mirror.aliyu… 替换成你的镜像：对于加速器的地址，您登录容器镜像服务控制台后，在左侧导航栏抉择 镜像工具 > 镜像加速器 ，在 镜像加速器 页面就会显示为您独立调配的加速器地址。

持续./setup.sh 设置, 跟踪 IP 地址

启动 the Graph

# docker-compose down -v
