虚拟机搭建FISCO BCOS基本环境

环境

Linux镜像 CentOS-7-x86_64-DVD-2003
虚拟机环境：2核，1.5G运存，20G存储

参考教程

https://fisco-bcos-documentation.readthedocs.io/zh_CN/latest/docs/installation.html

安装

环境安装
1. ```
sudo yum install -y openssl curl
```
2. 如果在虚拟机运行1. 报错，那么参考：https://blog.csdn.net/Wonz5130/article/details/84864233
3. ```
cd ~ && mkdir -p fisco && cd fisco
```
4. curl -#LO https://gitee.com/FISCO-BCOS/FISCO-BCOS/raw/master/tools/build_chain.sh && chmod u+x build_chain.sh

搭建单群组4节点联盟链

1.确保机器的30300~30303，20200~20203，8545~8548端口没有被占用。

查看机器所有的开启的端口
1. ```
netstat -ntlp
```
查看某一指定端口：例如80端口
```
 1. ```
    lsof -i tcp:80
    ```
```

使用脚本搭建节点

bash build_chain.sh -l "127.0.0.1:4" -p 30300,20200,8545

注释

    其中-p选项指定起始端口，分别是p2p_port,channel_port,jsonrpc_port
    出于安全性和易用性考虑，v2.3.0版本最新配置将listen_ip拆分成jsonrpc_listen_ip和channel_listen_ip，但仍保留对listen_ip的解析功能，详细请参考 这里
    为便于开发和体验，channel_listen_ip参考配置是 0.0.0.0 ，出于安全考虑，请根据实际业务网络情况，修改为安全的监听地址，如：内网IP或特定的外网IP

如果成功->会输出All completed, 报错参考nodes/build.log

启动链

启动所有节点

```
bash nodes/127.0.0.1/start_all.sh
```

如果 1. 成功会输出类似下面内容的响应。否则请使用netstat -an | grep tcp检查机器的30300~30303，20200~20203，8545~8548端口是否被占用

try to start node0
try to start node1
try to start node2
try to start node3
 node1 start successfully
 node2 start successfully
 node0 start successfully
 node3 start successfully

检查进程

ps -ef | grep -v grep | grep fisco-bcos

如果 1. 正常，会输出

fisco       5453     1  1 17:11 pts/0    00:00:02 /home/ubuntu/fisco/nodes/127.0.0.1/node0/../fisco-bcos -c config.ini
fisco       5459     1  1 17:11 pts/0    00:00:02 /home/ubuntu/fisco/nodes/127.0.0.1/node1/../fisco-bcos -c config.ini
fisco       5464     1  1 17:11 pts/0    00:00:02 /home/ubuntu/fisco/nodes/127.0.0.1/node2/../fisco-bcos -c config.ini
fisco       5476     1  1 17:11 pts/0    00:00:02 /home/ubuntu/fisco/nodes/127.0.0.1/node3/../fisco-bcos -c config.ini

检查日志输出

查看节点node0链接的节点数

tail -f nodes/127.0.0.1/node0/log/log*  | grep connected

正常情况会不停地输出链接信息，从输出可以看出node0与另外3个节点有链接。

info|2019-01-21 17:30:58.316769| [P2P][Service] heartBeat,connected count=3
info|2019-01-21 17:31:08.316922| [P2P][Service] heartBeat,connected count=3
info|2019-01-21 17:31:18.317105| [P2P][Service] heartBeat,connected count=3

执行下面指令，检查是否在共识

tail -f nodes/127.0.0.1/node0/log/log*  | grep +++

正常情况会不停输出++++Generating seal，表示共识正常

info|2019-01-21 17:23:32.576197| [g:1][p:264][CONSENSUS][SEALER]++++++++++++++++Generating seal on,blkNum=1,tx=0,myIdx=2,hash=13dcd2da...

配置及使用控制台

配置

安装JDK8及以上(使用orcale：https://www.oracle.com/technetwork/java/javase/downloads/index.html)
配置环境变量，并用java -version测试

下载控制台文件

cd ~/fisco && curl -#LO https://github.com/FISCO-BCOS/console/releases/download/v1.1.0/download_console.sh && bash download_console.sh

拷贝控制台配置文件

1. cp -n console/conf/applicationContext-sample.xml console/conf/applicationContext.xml
2. cp nodes/127.0.0.1/sdk/* console/conf/

启动控制台服务

cd ~/fisco/console && bash start.sh

输出下述信息表明启动成功否则请检查conf/applicationContext.xml中节点端口配置是否正确

部署及调用HelloWorld合约

HelloWorld合约

HelloWorld合约提供两个接口，分别是get()和set()，用于获取/设置合约变量name。合约内容如下:

pragma solidity ^0.4.24;

contract HelloWorld {
    string name;

    function HelloWorld() {
        name = "Hello, World!";
    }

    function get()constant returns(string) {
        return name;
    }

    function set(string n) {
        name = n;
    }
}

部署HelloWorld合约

为了方便用户快速体验，HelloWorld合约已经内置于控制台中，位于控制台目录下contracts/solidity/HelloWorld.sol，参考下面命令部署即可。

# 在控制台输入以下指令 部署成功则返回合约地址
[group:1]> deploy HelloWorld
contract address:0xb3c223fc0bf6646959f254ac4e4a7e355b50a344

调用HelloWorld合约

# 查看当前块高
input: getBlockNumber
= = =
output: 1

# 调用get接口获取name变量 此处的合约地址是deploy指令返回的地址
input:  call HelloWorld 0xb3c223fc0bf6646959f254ac4e4a7e355b50a344 get
= = =
output: Hello, World!

# 调用set设置name
input: call HelloWorld 0xb3c223fc0bf6646959f254ac4e4a7e355b50a344 set "Hello, FISCO BCOS"
0x21dca087cb3e44f44f9b882071ec6ecfcb500361cad36a52d39900ea359d0895
