Chang'an chain learning notes - Start Chang'an chain

1. Create a learning directory , Entry directory

# Create a learning directory
mkdir chainmaker-learn
# Entry directory
cd chainmaker-learn

2. Download the source code （ Go to the official registration account before downloading ）

# Download project source
git clone https://git.chainmaker.org.cn/chainmaker/chainmaker-go.git

# Download the source code of certificate tool
git clone -b v2.2.0 https://git.chainmaker.org.cn/chainmaker/chainmaker-cryptogen.git


3. Compile certificate generation tool

# Enter the certificate tool source code directory , structure
cd chainmaker-cryptogen
make


Be careful make Before , Make sure that... Is installed gcc, And the version is larger than 7.3

4. stay chainamker-go/tools Establish a certificate tool directory soft connection under the directory

# Enter the tool directory of the main source code
cd chainmaker-go/tools

#  Soft connection chainmaker-cryptogen To tools Under the table of contents
ln -s ../../chainmaker-cryptogen/ .


After establishing the soft connection , You can see... In the current directory chainmaker-cryptogen, It is actually the directory of certificate tools

5. Generate Certificate

Get into

chainmaker-go/scripts

Catalog , perform

prepare_pk.sh

Script generates single chain 4 Node cluster configuration , Stored in path

chainmaker-go/build

in

# Go to the script Directory
cd scripts/ 

# Generate 4 Nodes , Configuration of a chain
./prepare_pk.sh 4 1

When executing a script , Press all the way enter Default is good
The generated certificate directory is in /root/chainmaker-learn/chainmaker-go/build Under the table of contents

6. Build installation package

# stay scripts Execute the script in the directory ：
./build_release.sh

7. Start Chang'an chain

# Start Chang'an chain
$ ./cluster_quick_start.sh normal
# Close Chang'an chain
./cluster_quick_stop.sh

# Check whether the port number is activated
netstat -lptn | grep 1230

After starting , You can view the port number

There are mainly 2 Ports ：

（1）

p2p

port （ For node interconnection ）,

p2p

The starting port is

11301

（2）

rpc

port （ Used for communication between client and node ）,

rpc

The starting port is

12301

.

If you generate 4 Configuration of nodes ,

p2p

Ports are ：

11301、11302、11303、11304

,

rpc

Ports are ：

12301、12302、12303、12304
