Ubuntu中怎么搭建EOS测试环境

Ubuntu中怎么搭建EOS测试环境，相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。

1.下载源码

git clone https://github.com/EOSIO/eos --recursive

遇到的问题以及解决方案如下：

2.编译

cd eos (若已经在eos目录，可省去这一步)./eosio_build.sh

一路通畅未遇到任何问题

编译完成，如图所示

3.环境验证（可不做）

请参照安装完成的图，执行验证的相关命令，

export PATH=${HOME}/opt/mongodb/bin:$PATH    /home/guiren/opt/mongodb/bin/mongod -f /home/guiren/opt/mongodb/mongod.conf &cd /home/guiren/eos/buildmake test

验证结果

4.安装eos到系统环境

当期目录：eos

cd buildsudo make install

截图如下，

5.启动测试节点

当前目录：eos/build

cd programs/nodeos/./nodeos -e -p eosio --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin

启动成功文案如下

出现和上面类似的文案，说明已经在生产块了。

6.执行cleos命令查看相关信息

重新打开一个终端（之前生产节点的终端不要关闭）

当前目录：eos

cd build/programs/cleos./cleos get info  (查看网络信息)

网络信息如下，

cleos命令官方文档：https://developers.eos.io/eosio-cleos/reference#cleos-version

生成的块和配置信息默认在当前登录用户目录，

cd .local/share/eosio/nodeos/

删除这个目录，重启nodeos即可重置账号，智能合约等。

笔者建议各位开发人员将已经搭建好的eos压缩一份保存起来，下次可直接拿来使用，毕竟搭建环境也是个费时的过程。

打包到root目录命令，

tar -zcvf ~/eos_nodes_backup.tar.gz eos
