Windows installs the Nacos service, which you can view[ Learning notes of SpringCloudAlibaba [2] building Nacos service in Windows]

premise
    1. Operating system CentOs7
    1.1. Install Docker on centos7[ Install Docker]

Mode 1

Only Nacos server is deployed, and monitoring components such as prometheus/grafana are not used

edition

View the Docker version of Nacos: https://hub.docker.com/r/nacos/nacos-server/tags

​

Download

docker pull nacos/nacos-server:v2.0.4  #The stable version is recommended. If the version is not specified, it is the latest version (corresponding to the v2.0.4 version of nacos)

docker images  #View all image packages in docker

Run

After downloading the image package, you have to start the image package. Here are some more words to introduce the meaning of parameters, so as not to follow the steps
-v: Directory of a container: map a directory on centos (i.e. mount)
-p: External access port: internally mapped port (i.e. port)
-e: Environment variable settings
-d: Background operation
– Name: the name of the container
– restart: restart policy

docker run -d -e MODE=standalone  -v  /nacos/logs:/home/nacos/logs  -p 8848:8848  --name nacos --restart=always   nacos/nacos-server:v2.0.4

Or this command will work

docker run --env MODE=standalone --restart=always --name nacos -d -p 8848:8848 nacos/nacos-server:v2.0.4

Run successfully!  

Log

How to view logs?

Note: 10m is a time parameter, which is set according to the time you want to see

docker  ps     	#View containers that have been started
docker logs --since  10m   nacos Container for id      #View the output log of the specified container

One of the addresses drawn by the horizontal line is the ip address in the docker container. This is very important (the external connection uses the server ip + external mapping port, and the internal connection (a single service is also deployed on docker) uses the ip address of a container in the docker container and its internal port number

Effect

User name / password: nacos/nacos -- default

Modify the configuration of Nacos

How to modify the configuration of Nacos in Docker? Very simple, direct operation ~

docker  ps     #Check the started container and find the container id of nacso
docker  exec -it  nacos Container for id   /bin/bash    #Enter the container of nacso
exit  		   #Exit container

The following is how to change the Nacos configuration. Only the application Properties.

Mode 2

Deployed through docker compose, including prometheus/grafana and other monitoring components

Reference documents: https://nacos.io/zh-cn/docs/quick-start-docker.html

Premise

  Install git and docker-compose

Clone project
git clone https://github.com/nacos-group/nacos-docker.git
cd nacos-docker

standalone mode  Derby
docker-compose -f example/standalone-derby.yaml up

standalone mode  MySQL
 -- If you want to use MySQL5.7
    docker-compose -f example/standalone-mysql-5.7.yaml up
 -- If you want to use MySQL8
    docker-compose -f example/standalone-mysql-8.yaml up

Cluster mode
  docker-compose -f example/cluster-hostname.yaml up 

No effect display for network reasons!

Mode 3

As a supplement to method 1, it is deployed by using the configuration file mount method

Mount directory

mkdir -p /home/nacos/logs/                      #New logs directory
mkdir -p /home/nacos/init.d/          
vim /home/nacos/init.d/custom.properties        #Modify profile

Add the following parameters:

server.contextPath=/nacos
server.servlet.contextPath=/nacos
server.port=8848

spring.datasource.platform=mysql
