Building Nacos 2 based on docker compose (using MySQL for persistence)

2022-06-13 05:09:00 【Fried fried dough sticks】

List of articles

summary

I'm putting a SpringBoot Individual projects are migrated to Spring Cloud On the microservice project , First configuration Nacos 2 As the configuration center of the microservice project / Registry Center , And use MySQL Database pair Nacos As a persistence solution .

Installation steps

One 、 install Docker And Docker Compose

Docker Is an open source software , It's an open platform , For developing applications 、 deliver （shipping） application 、 Run the application . Docker Allow users to put infrastructure （Infrastructure） The applications in are separated separately , Form smaller particles （ Containers ）, To speed up the delivery of software .

Docker Install the reference ：https://docs.docker.com/engine/install/

Compose Is used to define and run multiple containers Docker Application tools . adopt Compose, You can use YML File to configure all the services the application needs . then , Use a command , You can start from YML Create and start all services in the file configuration .

Docker Compose Install the reference ：https://docs.docker.com/compose/install/

Two 、 function Docker Compose file

service.nacos.image yes nacos-server Mirror image , Bloggers use M1 Chip MacBook, Therefore, using zhusaidong/nacos-server-m1:2.0.3, be based on x86 Our readers can choose .

pcs-nacos And pcs-nacos-mysql It's my custom Container Name, Readers are free to modify .

version: '3'
services:
  nacos:
    image: zhusaidong/nacos-server-m1:2.0.3
    container_name: pcs-nacos
    environment:
      - MODE=standalone
    ports:
      - "8848:8848"
    depends_on:
      - mysql
  mysql:
    image: mysql:oracle
    container_name: pcs-nacos-mysql
    environment:
      - MYSQL_ALLOW_EMPTY_PASSWORD=yes

3、 ... and 、 stay MySQL In the container , establish Nacos Officially given databases and data tables

INSERT INTO roles (username, role) VALUES ('nacos', 'ROLE_ADMIN');

stay MySQL In the container , Create a database （database/schema）, Select database （use command ）, Execute the above SQL sentence .

Four 、 stay Nacos Server In a container MySQL Persistent configuration 

#  Enter the first  Nacos Server  Containers , edit  nacos  Under folder  conf  Under folder  application.properties  file , And make the following modifications 

spring.datasource.platform=mysql

# pcs-nacos-mysql  yes  Docker Compose  The name specified in the file 
db.url.0=jdbc:mysql://pcs-nacos-mysql:3306/nacos_mysql
#  Comment out  db.url.1
db.user=root
db.password=123456

5、 ... and 、 restart Nacos

restart Nacos Service to apply 「 Step four 」 Changes in .

6、 ... and 、 visit Nacos page

visit localhost:8848/nacos/ Log in to the website （ my Nacos Server The port that the container maps to the local machine is 8848）：

  • Initial username ：nacos
  • Initial password ：nacos

attach ： Based on the original Docker build Nacos 2（MySQL）
