Nacos cluster construction

I. Introduction

This article mainly introduces how to build a nacos cluster. The example uses 3 servers to build.

Tips: The following is the text of this article, the following cases are for reference

Second, installation preparation

Nacos is developed based on java, and its operation depends on the java environment.Depends on 64 bit JDK 1.8+, please install jdk by yourself.

1. Download

The download of nacos project is slow from github due to the influence of the network, and it can be downloaded from gitee

git clone https://gitee.com/mirrors/Nacos.git

2. Compile

Open the command line in the downloaded nacos root directory, execute mvn -Prelease-nacos -Dmaven.test.skip=true clean install -U to compile and package (maven environment needs to be installed), it is recommended to download the official compiled onepackage, the address is: https://github.com/alibaba/nacos/releases/download/1.3.0/nacos-server-1.3.0.tar.gz.
Copy nacos/distribution/target/nacos-server-1.3.0.tar.gz to the /app directory of server1.
Extract the tar -zxf nacos-server-1.3.0.tar.gz.

Third, modify related configuration

1. Modify the cluster configuration file /app/nacos/conf/cluster.conf

#Open the directory where the configuration file is located

cd /data/nacos/conf/

#Modify the cluster configuration file name

mv cluster.conf.example cluster.conf

#Modify cluster configuration

vim cluster.conf10.18.10.148:884810.18.10.149:884810.18.10.150:8848

2. Modify the data source configuration file /app/nacos/conf/application.properties

### If use MySQL as datasource:spring.datasource.platform=mysql### Count of DB:db.num=1### Connect URL of DB:db.url.0=jdbc:mysql://192.168.2.168:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTCdb.user=nacosdb.password=nacos123

3. Create database nacos and create account nacos/nacos123

CREATE USER 'nacos'@'%' IDENTIFIED BY 'nacos123';GRANT ALL ON nacos.* TO 'nacos'@'%';

4. Execute /app/nacos/conf/nacos-mysql.sql script

Fourth, copy nacos to the other two servers

scp -r /app/nacos/ [email protected]:/app/scp -r /app/nacos/ [email protected]:/app/

V. Start and log in to test

1. Start nacos with 3 servers

Execute the following command to start the nacos service

sh /app/nacos/startup.sh

2. Login test, default account password nacos/nacos

http://10.18.10.148:8848/nacos

http://10.18.10.149:8848/nacos

http://10.18.10.150:8848/nacos

Let me introduce myself first. The editor graduated from Jiaotong University in 2013. I worked in a small company and went to big factories such as Huawei and OPPO. I joined Ali in 2018, until now.I know that most junior and intermediate java engineers want to upgrade their skills, they often need to explore their own growth or sign up to study, but for training institutions, the tuition fee is nearly 10,000 yuan, which is really stressful.Self-learning that is not systematic is very inefficient and lengthy, and it is easy to hit the ceiling and the technology stops.Therefore, I collected a "full set of learning materials for java development" for everyone. The original intention is also very simple. I hope to help friends who want to learn by themselves but don't know where to start, and at the same time reduce everyone's burden.Add the business card below to get a full set of learning materials
