Detailed tutorial for springcloud alibaba nacos linux configuration

First download the compressed package of nacos from github: https://github.com/alibaba/nacos/releases

After the download is complete, transfer the file to the Linux server via WinSCP and then decompress the compressed package using the tar -zxvf command.

After decompression is complete, enter the conf directory

Open the clusmter.conf file and add

Save and exit through the :wq command, then enter startup.sh through the vim command

After the modification here is completed, find the bottom position of this file

Add the relevant configuration in the red box, save and exit, and then enter the conf file of nginx

Find the nginx.conf file and enter vim to modify the relevant ports of nginx load

The port number added in the upstream cluster is the three ports added in the nacos conf file before. The default port of nginx is 80, which I changed to 1111
After saving and exiting, you can
The ./nginx -c /usr/local/nginx/conf/nginx.conf command starts the nginx service.
-c means that when nginx starts, it reads the information in the configuration file /usr/local/nginx/conf/nginx.conf and then returns to nacos and enters the bin directory of nacos and starts nacos through ./startup.sh -p port number
After the startup is complete, you can use ps -ef|grep nacos|grep -v grep |wc -l to view how many nacos services are started.

I started three nacos services here and then changed the nacos path in the application.yml in the previous springcloud to the path and port number of nginx

Check whether the service is registered in nacos on Linux through the URL

Finally, because nacos integrates an embedded database by default, if you want to read the configuration of nacos into mysql, you can enter the conf directory of nacos, there is a nacos-mysql.sql open it, there are some tables and data needed by nacos, copy them out, put them in mysql and execute the following, then open application.properties

spring.datasource.platform=mysql
db.num=1
db.url.0=jdbc:mysql://127.0.0.1:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user=root
db.password=123456

Add the above code and modify it to your own mysql url, user and password. In the future, the configuration on nacos will be saved in mysql instead of the embedded database that comes with nacos.
