搭建EOS环境

【搭建EOS环境】

1、Ubuntu 18.04 下安装eosio

wget https://github.com/eosio/eos/releases/download/v1.4.4/eosio_1.4.4-1-ubuntu-18.04_amd64.deb
sudo apt install ./eosio_1.4.4--ubuntu-.04_amd64.deb

　　在~目录下创建 contracts 目录。

2、启动钱包。

keosd &

　　启动成功的话，可以看见下面的输出。

info  --26T06::24.789 thread-  wallet_plugin.cpp:          plugin_initialize    ] initializing wallet plugin
info  --26T06::24.795 thread-  http_plugin.cpp:           add_handler          ] add api url: /v1/keosd/stop
info  --26T06::24.796 thread-  wallet_api_plugin.cpp:      plugin_startup       ] starting wallet_api_plugin
info  --26T06::24.796 thread-  http_plugin.cpp:           add_handler          ] add api url: /v1/wallet/create
info  --26T06::24.796 thread-  http_plugin.cpp:           add_handler          ] add api url: /v1/wallet/create_key
info  --26T06::24.796 thread-  http_plugin.cpp:           add_handler          ] add api url: /v1/wallet/get_public_keys

3、启动nodeos

nodeos -e -p eosio \
--plugin eosio::producer_plugin \
--plugin eosio::chain_api_plugin \
--plugin eosio::http_plugin \
-d /home/ubuntu/contracts/eosio/data \
--config-dir /home/ubuntu/contracts/eosio/config \
--access-control-allow-origin=* \
--contracts-console \
--http-validate-host=false \
—filter-on=‘*’ >> nodeos.log >& &

These settings accomplish the following：

1. Using a work directory for blockchain data and configuration in eosio directory under the development directory. Here we use eosio/data and eosio/config respectively

2. Run the Nodeos. This command loads all the basic plugins, set the server address, enable CORS and add some contract debugging and logging.

3. Enable CORS with no restrictions (*)

　　通过以下命令检验是否成功运行nodeos

tail -f nodeos.log

　　如果有以下输出，则成功了。

4、使用cleos查看钱包

cleos wallet list

　　你应该看见如下输出：

Wallets:
[]

5、可以查看 ~/contracts/eosio/config/config.ini 文件，可以看到默认nodeos端口为8888.

　　

　　cleos默认通过localhost:8888来连接nodeos。

　　可以通过http来发起请求来测试这个端口。

curl http://localhost:7777/v1/chain/get_info
