搭建区块链网络
一、搭建单群组 FISCO BCOS 联盟链
1.安装依赖
- 首先需要安装 openssl curl
- 开发部署工具build_chain.sh
- 安装 unzip 工具
sudo yum install -y openssl openssl-devel使用以下命令来安装 unzip 工具：sudo yum install unzip2.创建操作目录, 下载安装脚本
## 创建操作目录cd ~ && mkdir -p fisco && cd fisco## 下载脚本curl -#LO https://github.com/FISCO-BCOS/FISCO-BCOS/releases/download/v2.9.1/build_chain.sh && chmod u+x build_chain.sh如果因为网络问题导致长时间无法下载build_chain.sh脚本请尝试 curl -#LO https://osp-1257653870.cos.ap-guangzhou.myqcloud.com/FISCO-BCOS/FISCO-BCOS/releases/v2.9.1/build_chain.sh && chmod u+x build_chain.sh3.搭建单群组4节点联盟链
bash build_chain.sh -l 127.0.0.1:4 -p 30300,20200,8545命令执行成功会输出All completed。如果执行出错，请检查nodes/build.log文件中的错误信息
提示[WARN] /root/fisco/nodes DIR exists,please clean old DIR! 执行以下命令清除已有旧数据rm -rf /root/fisco/nodes4.启动FISCO BCOS链
bash nodes/127.0.0.1/start_all.sh启动成功会输出类似下面内容的响应。否则请使用netstat-an|greptcp检查机器的30300~30303，20200~20203，8545~8548端口是否被占用。
使用以下命令进行查找端口是否被占用netstat -anp | grep 30300try to start node0try to start node1try to start node2try to start node3 node1 start successfully node2 start successfully node0 start successfully node3 start successfully提示报错，如果docker启动失败的话请使用以下命令：
提示信息如：ERROR：Cannot connect to the Docker daemon at unix:///var/run/docker.sock.Is the docker daemon running?如何提示docker启动失败的话，执行以下命令：sudo systemctl start docker5.检查进程
ps -ef | grep -v grep | grep fisco-bcos正常情况会有类似下面的输出； 如果进程数不为4，则进程没有启动（一般是端口被占用导致的）
fisco 5453 11 17:11 pts/000:00:02 /home/ubuntu/fisco/nodes/127.0.0.1/node0/../fisco-bcos -c config.inifisco 5459 11 17:11 pts/000:00:02 /home/ubuntu/fisco/nodes/127.0.0.1/node1/../fisco-bcos -c config.inifisco 5464 11 17:11 pts/000:00:02 /home/ubuntu/fisco/nodes/127.0.0.1/node2/../fisco-bcos -c config.inifisco 5476 11 17:11 pts/000:00:02 /home/ubuntu/fisco/nodes/127.0.0.1/node3/../fisco-bcos -c config.ini6.检查日志输出
## 如下，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连接信息，从输出可以看出node0与另外3个节点有连接。info|2019-01-21 17:30:58.316769| [P2P][Service] heartBeat,connected count=3info|2019-01-21 17:30:58.316769| [P2P][Service] heartBeat,connected count=3info|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|2020-12-22 17:24:43.729402|[g:1][CONSENSUS][SEALER]++++++++++++++++ Generating seal on,blkNum=1,tx=0,nodeIdx=1,hash=2e133146...info|2020-12-22 17:24:47.740603|[g:1][CONSENSUS][SEALER]++++++++++++++++ Generating seal on,blkNum=1,tx=0,nodeIdx=1,hash=eb199760...二、配置及使用控制台
1.安装Java
！！！ 必须安装java14才可以本人安装时是2.9.2的控制台// 下载java14安装包jdk-14.0.2_linux-x64_bin.tar.gzhttps://www.oracle.com/cn/java/technologies/javase/jdk14-archive-downloads.html// 下载保存到cd /usr/local/source/java// 解压命令tar -zxvf jdk-14.0.2_linux-x64_bin.tar.gz// 将解压后的包移动到路径下mv jdk-14.0.2 /usr/local/soft/// 配置环境变量vi /etc/profile// 将以下命令复制到最后一行export JAVA_HOME=/usr/local/soft/jdk-14.0.2export JRE_HOME=${JAVA_HOME}/jreexport CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/libexport PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin// 刷新环境变量source /etc/profile2.安装maven（可以跳过）
切换路径cd /usr/lib使用 yum 命令安装 Java 开发包：sudo yum install java-devel下载并解压 Maven 安装包wget https://mirror-hk.koddos.net/apache/maven/maven-3/3.8.4/binaries/apache-maven-3.8.4-bin.tar.gztar -zxvf apache-maven-3.8.4-bin.tar.gz配置 Maven 环境变量sudo vi /etc/profile 将以下内容添加到 /etc/profile 文件末尾：export M2_HOME=[your-maven-directory]export PATH=$PATH:$M2_HOME/bin重新加载 /etc/profile 文件并应用更改：source /etc/profile检查 Maven 是否正确安装mvn -version之后，使用 Maven 在 CentOS 系统上下载 netty-tcnative例如，您可以使用以下命令从 Maven 中央仓库下载 netty-tcnative（版本为2.0.32.Final）：mvn dependency:get -Dartifact=io.netty:netty-tcnative:2.0.32.Final3.下载共享库 native library（可以跳过）
安装 netty-tcnativesudo yum install apr-devel openssl-develwget http://repo.maven.apache.org/maven2/io/netty/netty-tcnative/2.0.21.Final/netty-tcnative-2.0.21.Final-linux-x86_64.jar创建一个名为 netty-tcnative-2.0.21.Final-linux-x86_64.so 的链接文件，该文件指向 netty-tcnative-2.0.21.Final-linux-x86_64.jar 文件中的本机库ln -s /netty-tcnative-2.0.21.Final-linux-x86_64.jar \/usr/local/lib/libnetty-tcnative-2.0.21.Final-linux-x86_64.so在启动 FISCO BCOS 控制台之前，请确保将 /usr/local/lib 目录添加到系统路径中export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH4.获取控制台并回到fisco目录
cd ~/fisco && curl -LO https://github.com/FISCO-BCOS/console/releases/download/v2.9.2/download_console.sh && bash download_console.sh如果因为网络问题导致长时间无法下载，请尝试 cd ~/fisco && curl -#LO https://gitee.com/FISCO-BCOS/console/raw/master-2.0/tools/download_console.sh && bash download_console.sh5.拷贝控制台配置文件
# 最新版本控制台使用如下命令拷贝配置文件cp -n console/conf/config-example.toml console/conf/config.toml6.配置控制台证书
# 最新版本控制台使用如下命令拷贝配置文件cp -n console/conf/config-example.toml console/conf/config.tom启动！！！！
cd ~/fisco/console && bash start.shcentos 中启动fisco控制台时提示[root@gen-173-168-063-126 fisco]# cd console && bash start.shcreate BcosSDK failed, error info: init channel network error!org.fisco.bcos.sdk.network.NetworkException:* TRACE INFORMATION:----------------------------====> STEP1: try to connect nodes with ecdsa context...<==== STEP1-1: Load certificates for ecdsa context success...<==== connect nodes failed, reason:Failed to connect to all the nodes!* connect to 127.0.0.1:20200 failed!
