Caliper压力测试（具体步骤+示例）

一、Caliper压力测试指南

1. 环境要求

（1）配置基本环境

• 部署Caliper的计算机需要有外网权限；

  
  

  解决方法：

  #通常情况下，DNS 服务器由你的网络配置提供。你可以查看当前的 DNS 设置：
  
  cat /etc/resolv.conf
  
  oot@thy-virtual-machine:/home/thy/fisco# cat /etc/resolv.conf
  # This is /run/systemd/resolve/stub-resolv.conf managed by man:systemd-resolved(8).
  # Do not edit.
  #
  # This file might be symlinked as /etc/resolv.conf. If you're looking at
  # /etc/resolv.conf and seeing this text, you have followed the symlink.
  #
  # This is a dynamic resolv.conf file for connecting local clients to the
  # internal DNS stub resolver of systemd-resolved. This file lists all
  # configured search domains.
  #
  # Run "resolvectl status" to see details about the uplink DNS servers
  # currently in use.
  #
  # Third party programs should typically not access this file directly, but only
  # through the symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a
  # different way, replace this symlink by a static file or a different symlink.
  #
  # See man:systemd-resolved.service(8) for details about the supported modes of
  # operation for /etc/resolv.conf.
  
  nameserver 127.0.0.53
  options edns0 trust-ad
  search .
  

  #确保 nameserver 条目指向正确的 DNS 服务器。如果看起来不正确或有问题，可以尝试手动修改为已知可靠的 DNS 服务器，如 Google 的公共 DNS：
  
  echo "nameserver 8.8.8.8" > /etc/resolv.conf 或者
  vim /etc/resolv.conf
  
  # This is /run/systemd/resolve/stub-resolv.conf managed by man:systemd-resolved(8).
  # Do not edit.
  #
  # This file might be symlinked as /etc/resolv.conf. If you're looking at
  # /etc/resolv.conf and seeing this text, you have followed the symlink.
  #
  # This is a dynamic resolv.conf file for connecting local clients to the
  # internal DNS stub resolver of systemd-resolved. This file lists all
  # configured search domains.
  #
  # Run "resolvectl status" to see details about the uplink DNS servers
  # currently in use.
  #
  # Third party programs should typically not access this file directly, but only
  # through the symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a
  # different way, replace this symlink by a static file or a different symlink.
  #
  # See man:systemd-resolved.service(8) for details about the supported modes of
  # operation for /etc/resolv.conf.
  
  nameserver 8.8.8.8  ####修改为8.8.8.8
  options edns0 trust-ad
  search localdomain
  ~                                                                                                                                   
  ~                                                                                                                                   
  ~                     
  

  #如果你对配置进行了更改，可能需要重新启动 systemd-resolved 服务使其加载新的配置：
  
  sudo systemctl restart systemd-resolved
  
  

• 操作系统版本需要满足以下要求：Ubuntu >= 16.04、CentOS >= 7或MacOS >= 10.14；

• 部署Caliper的计算机需要安装有以下软件：python 2.7、make、g++、gcc及git。

2. NodeJS

• 版本要求：

  NodeJS 8 (LTS), 9, 或 10 (LTS)，Caliper尚未在更高的NodeJS版本中进行过验证。

• 安装指南：

  建议使用nvm(Node Version Manager)安装，nvm的安装方式如下：

# 安装nvm
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.2/install.sh | bash

# 若出现因网络问题导致长时间下载失败，可尝试以下命令
curl -o- https://gitee.com/mirrors/nvm/raw/v0.33.2/install.sh | bash

# 加载nvm配置
source ~/.$(basename $SHELL)rc
# 安装Node.js 8
nvm install 8
# 使用Node.js 8
nvm use 8

查看可用版本：

nvm ls-remote

安装具体版本

nvm install 8.17.0

验证安装：

3.部署Docker

# 更新包索引
sudo apt-get update
# 安装基础依赖库
sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg-agent \
    software-properties-common
# 添
