子任务1-2-1： 搭建区块链系统并验证

采用默认配置搭建区块链网络

使用 build_chain.sh在本机搭建一条4节点区块链系统，-l指定IP，-p指定端口，-e指定本地 fisco-bcos，不指定则去GitHub自动下载

[root@localhost tools]# bash build_chain.sh -l 127.0.0.1:4 -p 30300,20200,8545 -e /root/tools/fisco-bcos

启动节点

[root@localhost tools]# cd /root/tools/nodes/127.0.0.1/
[root@localhost 127.0.0.1]# bash start_all.sh 
try to start node0
try to start node1
try to start node2
try to start node3
 node3 start successfully
 node2 start successfully
 node0 start successfully
 node1 start successfully
通过命令验证区块链节点进程运行状况
[root@localhost 127.0.0.1]# ps -ef | grep -v grep | grep fisco-bcos

通过命令验证区块链连接状态和共识状态日志输出

验证区块链连接状态

使用 tail，关键词 connected，这里查看 node0节点一共有3个节点连接

[root@localhost 127.0.0.1]# tail -f /root/tools/nodes/127.0.0.1/node0/log/log* | grep connected

验证区块链共识状态

使用 tail，关键词 ++，这里查看 node0节点它在 [g:1]群组中

[root@localhost 127.0.0.1]# tail -f /root/tools/nodes/127.0.0.1/node0/log/log* | grep ++

子任务1-2-2：搭建区块链系统管理平台并验证

配置控制台，管理相关证书并启动

切换到 root/tools/console目录下，并且把节点的 SDK目录下的文件全部拷贝到 conf目录下

cd /root/tools/console
cp /root/tools/nodes/127.0.0.1/sdk/* ./conf/

进入 conf目录，拷贝 config-example.toml文件为 config.toml回到 root/tools/console目录启动控制台

[root@localhost console]# bash start.sh

子任务1-2-3：区块链节点运维

获取指定区块链节点输出等级为警告级，并设置日志存储阈值位100MB并验证

这里是指定节点设置，正常比赛中会要求那个节点，这里设置 node0节点，切到 node0目录中，编辑 config.ini，找到 [log]，修改 level为 warning 和 max_log_file_size=200 为 100

[log]
    enable=true
    log_path=./log
    ; enable/disable the statistics function
    enable_statistic=false
    ; network statistics interval, unit is second, default is 60s
    stat_flush_interval=60
    ; info debug trace
    level=warning
    ; MB
    max_log_file_size=100
    flush=true

重启节点

[root@localhost node0]# bash stop.sh && bash start.sh 
 stop node0 success.
 node0 start successfully

验证

正常节点是不会输出 warning日志，使用刚才的 tail查看一下,会发现什么也不输出

[root@localhost node0]# tail -f /root/tools/nodes/127.0.0.1/node0/log/log* | grep +++
通过给定工具（地址/root/tools）完成新节点（node4）配置

使用 gen_node_cert.sh生成一共新节点，-c，指定密钥位置 ，-o指定节点存储位置

[root@localhost tools]# bash gen_node_cert.sh -c /root/tools/nodes/cert/agency/ -o /root/tools/nodes/127.0.0.1/node4
gen_node_cert.sh:行151: xxd: 未找到命令
==============================================================
[INFO] Cert Path   : /root/tools/nodes/cert/agency/
[INFO] Output Dir  : /root/tools/nodes/127.0.0.1/node4
==============================================================
[INFO] All completed. Files in /root/tools/nodes/127.0.0.1/node4

再进入 node4目录中，方便拷贝配置文件，把 node0 中的 start.sh stop.sh config.ini 拷贝到 node4目录下，在拷贝 node0/conf下的群组文件，group.1.ini group.1.genesis，拷贝到 node4/conf目录下

[root@localhost conf]# cd /root/tools/nodes/127.0.0.1/node4/
[root@localhost node4]# cp /root/tools/nodes/127.0.0.1/node0/start.sh ./
[root@localhost node4]# cp /root/tools/nodes/127.0.0.1/node0/stop.sh ./
[root@localhost node4]# cp /root/tools/nodes/127.0.0.1/node0/config.ini ./
[root@localhost node4]# cp /root/tools/nodes/127.0.0.1/node0/conf/group.1.ini ./conf
[root@localhost node4]# cp /root/tools/nodes/127.0.0.1/node0/conf/group.1.genesis ./conf
[root@localhost node4]# ls
conf  config.ini  start.sh  stop.sh

修改配置文件 config.ini，。对于 [rpc]模块，修改 channel_listen_port=20204和 jsonrpc_listen_port=8549；对于 [p2p]模块，修改 listen_port=30304并在 node.中增加自身节点信息；

[rpc]
    channel_listen_ip=0.0.0.0
    channel_listen_port=20204
    jsonrpc_listen_ip=127.0.0.1
    jsonrpc_listen_port=8549
[p2p]
    listen_ip=0.0.0.0
    listen_port=30304
    ; nodes to connect
    node.0=127.0.0.1:30300
    node.1=127.0.0.1:30301
    node.2=127.0.0.1:30302
    node.3=127.0.0.1:30303
    node.4=127.0.0.1:30304
启动新节点加入区块链系统并验证

启动节点

[root@localhost node4]# bash start.sh 
 node4 start successfully

查看 node4的 id

[root@localhost node4]# cat /root/tools/nodes/127.0.0.1/node4/conf/node.nodeid 
724921f710711316d0bcc4ddb87f337e2f99782a35ead8c7b788cf6a93e1f4abc41efdecb03e0f12b132812b7c6235d693d8a1ecd5ae9c7f50591e304a8f2b71

再次进入控制台，把节点设置成 共识节点 ，使用 addSealer

[root@localhost console]# bash /root/tools/console/start.sh
=============================================================================================

[group:1]> addSealer 724921f710711316d0bcc4ddb87f337e2f99782a35ead8c7b788cf6a93e1f4abc41efdecb03e0f12b132812b7c6235d693d8a1ecd5ae9c7f50591e304a8f2b71
{
    "code":1,
    "msg":"Success"
}

加入成功，用 tail,查看 node0节点连接情况，验证是否加入成功（刚才把 node0节点的日志输出改成 warning 了，需要修改回来为 info，并重新启动）

[root@localhost node0]# tail -f /root/tools/nodes/127.0.0.1/node0/log/log* | grep connected
info|2024-03-08 15:54:00.833135|[P2P][Service] heartBeat,connected count=4
info|2024-03-08 15:54:10.834152|[P2P][Service] heartBeat,connected count=4

这里的 connected conunt 为4，证明新节点已经加入成功

子任务1-2-4：区块链网络运维

设置区块链系统黑名单，将node3设为黑名单禁止连接，并验证

查看 node3的id

[root@localhost node0]# cat /root/tools/nodes/127.0.0.1/node3/conf/node.nodeid 
1971793aee3e24b79e04e21cd619ee2f6fe21ccda019f1b56b197be8b16e6717c2dda5abc979ded90518efd91e77cf2f2ecc3f3b7dad716237b9ae501a1a7bac

修改 node0的 config.ini文件 ，将 certifcate_blacklist[黑名单]字段添加 node3的节点id

[certificate_blacklist]
    ; crl.0 should be nodeid, nodeid's length is 128
    crl.0=1971793aee3e24b79e04e21cd619ee2f6fe21ccda019f1b56b197be8b16e6717c2dda5abc979ded90518efd91e77cf2f2ecc3f3b7dad716237b9ae501a1a7bac

重启 node0，节点再用 tail查看节点连接状态

[root@localhost node0]# bash stop.sh && bash start.sh 
 stop node0 success.
 node0 start successfully
[root@localhost node0]# tail -f /root/tools/nodes/127.0.0.1/node0/log/log* | grep connected
info|2024-03-08 16:05:47.634483|[P2P][Service] heartBeat,connected count=3
info|2024-03-08 16:05:57.635824|[P2P][Service] heartBeat,connected count=3

这里可以看到，连接数只有3个了，证明已经设置成功，node1 node2 node4，一样这样配置

设置系统中区块打包最大交易数量设为2000

进入控制台，使用 setSystemConfigByKey设置 tx_count_limit

[group:1]> setSystemConfigByKey tx_count_limit 2000
验证区块最大打包交易数量情况
[group:1]> getSystemConfigByKey tx_count_limit 
2000
