其他：一、使用docker部署区块链（ubuntu18.04）-JAVA

./build_chain.sh: illegal option -- -
Usage:
    -l                         [Required] "ip1:nodeNum1,ip2:nodeNum2" e.g:"192.168.0.1:2,192.168.0.2:3"
    -f                    [Optional] split by line, every line should be "ip:nodeNum agencyName groupList p2p_port,channel_port,jsonrpc_port". eg "127.0.0.1:4 agency1 1,2 30300,20200,8545"
    -v       Default is the latest v2.8.0
    -e          Default download fisco-bcos from GitHub. If set -e, use the binary at the specified location
    -o 
                     Default ./nodes/
    -p                      Default 30300,20200,8545 means p2p_port start from 30300, channel_port from 20200, jsonrpc_port from 8545
    -q        List FISCO-BCOS released versions
    -i                         Default 127.0.0.1. If set -i, listen 0.0.0.0
    -s                         Default rocksdb. Options can be rocksdb / mysql / scalable, rocksdb is recommended
    -d                     Default off. If set -d, build with docker
    -c             Default PBFT. Options can be pbft / raft /rpbft, pbft is recommended
    -C                        Default 1. Can set uint.
    -g            Default no
    -z             Default no
    -t                Default auto generate
    -6                        Default no. If set -6, treat IP as IPv6
    -k             Default auto generate, the ca.crt and ca.key must in the path, if use intermediate the root.crt must in the path
    -K   Default auto generate, the gmca.crt and gmca.key must in the path, if use intermediate the gmroot.crt must in the path
    -D             Default false, If set -D, use deploy mode directory struct and make tar
    -G       Default false, only works for guomi mode
    -X     Default 36500 days
    -T                Default off. If set -T, enable debug log
    -S               Default off. If set -S, enable statistics
    -F          Default on. If set -F, disable log auto flush
    -E         Default off. If set -E, enable free_storage_evm
    -h Help
e.g
    ./build_chain.sh -l "127.0.0.1:4"

执行命令

cd ~/fisco/nodes/127.0.0.1 && ./start_all.sh

启动时，会查找本地是否存在FISCO-BCOS对应版本的节点镜像，不存在则从docker hub下载。

检查容器状态是否正常，命令如下:

docker ps -a | egrep fiscobcos

容器状态为UP时，说明节点正常启动。

可以通过检查日志来确认节点的p2p连接数目、共识是否正常。

tail -f ~/fisco/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5个节点有连接。

检查共识

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

到此docker环境已经部署完成。
