设置本地网络 (Setting up a local network)

启动本地网络 (Spinning up a local network)

先决条件 (Prerequisites)

为了运行本地网络，必须从源代码安装 Namada。

有一个专门为此目的编写的scripts，可以在 Namada 仓库的脚本下找到。

安装脚本依赖项 (Installing script dependencies)

脚本有一些必须安装的依赖项，以便成功运行它：

• 必须安装 python3。

• 必须安装 toml Python pip 库 https://pypi.org/project/toml/。

脚本将需要一个创世配置文件，该文件是一个 TOML 文件，用于指定网络的参数。此类文件的示例可以在 anoma-network-config 仓库的templates目录中找到。

修改创世配置文件 (Modifying the genesis configuration file)

为了成功运行脚本，必须从 toml 文件中删除所有验证器部分。这是因为脚本将为网络生成一组新的验证器。

下面的代码块显示了一个已经修改过的，以删除验证器部分的创世配置文件示例。

构建 wasm (Building wasm)

该脚本还需要构建所有用于交易的 wasm 文件。可以通过运行以下命令完成此操作（同时位于 namada 目录中）：

make build-wasm-scripts

---

运行脚本 (Running the script)

该脚本名为 build_network.sh，可以使用以下命令运行：

# Ensure you are in the root of the namada repository directory
./scripts/build_network.sh <config_toml> <namada_dir> <OPTIONAL: base_dir>

更具体地说，该脚本接受三个参数：

• config_toml: 到（无验证器的）创世配置文件的路径。

• namada_dir: 到 Namada 二进制文件目录的路径。如果使用 make build-release 构建了二进制文件，这将意味着 namada/target/release 目录。否则，如果使用 make build 构建它们，则为 namada/target/debug 目录。

• base_dir: （可选参数）到 BASE_DIR 目录的路径，其中存储所有链数据。只有在 BASE_DIR 不是 namadac utils default-base-dir 命令给出的默认值时，才需要这样做。

例如，MacOS 用户可能会运行类似以下内容的命令：

./scripts/build_network.sh \
~/anoma-network-config/templates/edited_genesis_config.toml \
./target/release # Assuming the binaries were built using `make build-release`

---

运行账本 (Running the ledger)

运行脚本后，一个 python 进程将在后台启动。可以通过熟悉的命令运行账本：

target/release/namada ledger # Assuming the binaries were built using `make build-release`

---

清理 (Cleaning up)

在本地网络实现其目的后，可以通过运行脚本的 cleanup 函数中找到的以下命令进行清理：

    pkill -f ".hack/chains"
    rm -r .hack/chains
    rm local.*.tar.gz
