nacos installation steps

This tutorial is for the nacos version: 2.0.1, different versions may be slightly different.

Official website download address:

https://github.com/alibaba/nacos/tags

I downloaded version 2.0.1

1. Unzip the installation package

tar -xvf nacos-server-2.0.1.tar.gz

2. Create a mysql database

The SQL file is in the config folder under the decompressed file, nacos-mysql.sql

Various data of nacos are stored in mysql database

Create a nacos-mysql database on the MySQL server and import the SQL file into it

3. Edit the configuration file application.properties

Edit the port number:

### Default web context path:
server.servlet.contextPath=/nacos
### Default web server port:
server.port=5555

Uncomment the database

### If use MySQL as datasource:
spring.datasource.platform=mysql

### Count of DB:
db.num=1

Edit the address of the database connection

### Connect URL of DB:
db.url.0=jdbc:mysql://mysql.xxx.tech:3306/nacos_prod?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user.0=nacos
db.password.0=nacos

Add database connection pool configuration

### Connection pool configuration: hikariCP
db.pool.config.connectionTimeout=30000
db.pool.config.validationTimeout=10000
db.pool.config.maximumPoolSize=20
db.pool.config.minimumIdle=2

The complete configuration is as follows, redundant comments have been deleted

### Metrics for elastic search
management.metrics.export.elastic.enabled=false
#management.metrics.export.elastic.host=http://localhost:9200

### Metrics for influx

#*************** Access Log Related Configurations ***************#
### If turn on the access log:
server.tomcat.accesslog.enabled=false

### The access log pattern:
server.tomcat.accesslog.pattern=%h %l %u %t "%r" %s %b %D %{User-Agent}i %{Request-Source}i

### The directory of access log:
server.tomcat.basedir=


#*************** Access Control Related Configurations ***************#


### The ignore urls of auth, is deprecated in 1.2.0:
nacos.security.ignore.urls=/,/error,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-ui/public/**,/v1/auth/**,/v1/console/health/**,/actuator/**,/v1/console/server/**

### The auth system to use, currently only 'nacos' is supported:
nacos.core.auth.system.type=nacos

### If turn on auth system:
nacos.core.auth.enabled=false

### The token expiration in seconds:
nacos.core.auth.default.token.expire.seconds=18000

### The default token:
nacos.core.auth.default.token.secret.key=SecretKey012345678901234567890123456789012345678901234567890123456789

### Turn on/off caching of auth information. By turning on this switch, the update of auth information would have a 15 seconds delay.
nacos.core.auth.caching.enabled=true

### Since 1.4.1, Turn on/off white auth for user-agent: nacos-server, only for upgrade from old version.
nacos.core.auth.enable.userAgentAuthWhite=true

### Since 1.4.1, worked when nacos.core.auth.enabled=true and nacos.core.auth.enable.userAgentAuthWhite=false.
### The two properties is the white list for auth and used by identity the request from other server.
nacos.core.auth.server.identity.key=
nacos.core.auth.server.identity.value=

#*************** Istio Related Configurations ***************#
### If turn on the MCP server:
nacos.istio.mcp.server.enabled=false

If you configure a cluster, you need to modify cluster.conf.example

Add the IP+port number of nacos of other nodes inside

4. Enter the bin directory to start nacos

 ./startup.sh

Successful installation
