3. 通过Docker部署链
以证书账户模式的链为例，其他账户模式的链，流程类似，可自行借鉴
3.1. 使用chainmaker-go自带证书启动docker链
注：此为自行编译docker 镜像示例，若想使用最新官网镜像，请修改镜像名称。查看镜像
cd chainmaker-go/scripts/docker/2.3.0
# 启动
./four-nodes_up.sh
# 等待10s左右，发交易
cd .. && ./sendTx.sh
# 停止并删除数据
./2.3.0/four-nodes_down.sh
3.2. 使用新生成的证书启动docker链
3.2.1. 配置证书生成节点个数
进入
chainmaker-go/tools/chainmaker-cryptogen/config目录，修改crypto_config_template.yml文件中count
crypto_config:
- domain: chainmaker.org
host_name: wx-org
count: 4 # change this what you want, example is 7 node
3.2.2. 证书生成
进入chainmaker-go/scripts目录，执行prepare.sh脚本生成单链4节点集群配置，存于路径chainmaker-go/build中
# 进入脚本目录
$ cd ../scripts
# 查看脚本帮助
$ ./prepare.sh -h
Usage:
prepare.sh node_cnt(1/4/7/10/13/16) chain_cnt(1-4) p2p_port(default:11301) rpc_port(default:12301)
eg1: prepare.sh 4 1
eg2: prepare.sh 4 1 11301 12301
# 生成单链4节点集群的证书和配置
$ ./prepare.sh 4 1
begin check params...
begin generate certs, cnt: 4
input consensus type (0-SOLO,1-TBFT(default),3-HOTSTUFF,4-RAFT,5-DPOS):
input log level (DEBUG|INFO(default)|WARN|ERROR):
enable docker vm (YES|NO(default))
begin generate node1 config...
begin generate node2 config...
begin generate node3 config...
begin generate node4 config...
# 查看生成好的节点证书和配置
$ tree -L 3 ../build/
../build/

3.2.3. 镜像配置
进入
chainmaker-go/scripts/docker/multi_node目录，修改create_docker_compose_yml.sh中IMAGE为所需镜像
P2P_PORT=$1
RPC_PORT=$2
NODE_COUNT=$3
CONFIG_DIR=$4
SERVER_COUNT=$5
IMAGE="chainmakerofficial/chainmaker:v2.2.0" # change this
3.2.4. 创建docker-compose.yaml文件
将生成的证书配置文件放到
scripts/docker/multi_node目录中，然后修改对应chainmaker.yml文件中的本地ip使用
create_docker_compose_yml.sh进行docker-compose.yml文件生成
$ cd chainmaker-go
$ cp -rf build/config scripts/docker/multi_node/
$ cd scripts/docker/multi_node
# change ip what you want(LAN IP of the container), as 192.168.1.35 not localhost or 127.0.0.1
$ sed -i "s%127.0.0.1%192.168.1.35%g" config/node*/chainmaker.yml
# check help
$ ./create_docker_compose_yml.sh
Usage:
create_yml.sh P2P_PORT RPC_PORT NODE_COUNT CONFIG_DIR SERVER_NODE_COUNT
P2P_PORT: peer to peer connect
RPC_PORT: sdk to peer connect
NODE_COUNT: total node count
CONFIG_DIR: all node config path, relative or absolute
SERVER_NODE_COUNT: default:100, number of nodes per server
eg: ./create_docker_compose_yml.sh 11301 12301 4 ./config : 4 nodes in 1 machine
eg: ./create_docker_compose_yml.sh 11301 12301 16 ./config 2 : 4 nodes in 8 machine, 2 nodes per machine
eg: ./create_docker_compose_yml.sh 11301 12301 4 /data/workspace/chainmaker-go/build/config 4
$ ./create_docker_compose_yml.sh 11331 12331 7 ./config 4
$ tree -L 1

3.2.5. 启动节点
$ cd chainmaker-go/scripts/docker/multi_node/
# 启动节点
$ docker-compose -f docker-compose1.yml up -d
# or
$./start.sh docker-compose1.yml
3.2.6. 停止节点
$ cd chainmaker-go/scripts/docker/multi_node/
# 停止节点
$ docker-compose -f docker-compose1.yml down
# or
$./stop.sh docker-compose1.yml
3.2.7. 查看节点是否存在
查看进程
$ ps -ef|grep chainmaker | grep -v grep
25261 2146 4 19:55 pts/20 00:00:01 ./chainmaker start -c ../config/wx-org1.chainmaker.org/chainmaker.yml
25286 2146 4 19:55 pts/20 00:00:01 ./chainmaker start -c ../config/wx-org2.chainmaker.org/chainmaker.yml
25309 2146 4 19:55 pts/20 00:00:01 ./chainmaker start -c ../config/wx-org3.chainmaker.org/chainmaker.yml
25335 2146 4 19:55 pts/20 00:00:01 ./chainmaker start -c ../config/wx-org4.chainmaker.org/chainmaker.yml
查看端口
$ netstat -lptn | grep 1230
tcp6 0 0 :::12301 :::* LISTEN 25261/./chainmaker
tcp6 0 0 :::12302 :::* LISTEN 25286/./chainmaker
tcp6 0 0 :::12303 :::* LISTEN 25309/./chainmaker
tcp6 0 0 :::12304 :::* LISTEN 25335/./chainmaker
查看日志
$ cat ../build/release/*/bin/panic.log
$ cat ../build/release/*/log/system.log
$ cat ../build/release/*/log/system.log |grep "ERROR\|put block\|all necessary"
//若看到all necessary peers connected则表示节点已经准备就绪。
3.2.8. 部署/调用合约验证链是否正常
启动成功后，可进行部署/调用示例合约，以检查链功能是否正常。部署合约的使用教程可详见：部署示例合约。
