一、克隆源码

1.1. git 克隆源码

git clone https://github.com/alibaba/nacos.git

切换tag到3.1.1

git checkout tags/3.1.1

1.2. 直接点击下载

直接下载也可以
https://github.com/alibaba/nacos/archive/refs/tags/3.1.1.zip

二、修改源码集成PostgreSQL

2.1. 创建postgresql目录

<dependency>
    <groupId>com.sinhy</groupId>
    <artifactId>nacos-postgresql-datasource-plugin-ext</artifactId>
    <version>3.1.1</version>
</dependency>

三、编译源码

在idea中 执行mvn命令

mvn -Prelease-nacos -Dmaven.test.skip=true -Dcheckstyle.skip=true -Drat.numUnapporovedLicenses=100 clean install -U

编译成功的程序

四、启动本地nacos

修改配置
进入nacos\distribution\target\nacos-server-3.1.1\nacos\conf，修改application.properties，核心配置如下:

nacos.core.auth.server.identity.key=identityNacos
nacos.core.auth.server.identity.value=RTY4+Y4KokLKk9fZigOa3cwzRUzU2Nzs75m9oHHuiQE=
nacos.core.auth.plugin.nacos.token.secret.key=hzMOOvOp6gBXFCgK03caEETxQNF220HuiHALQApnDnQgM2JXgOB1iJrjM70wLTxNYlKxIaeCnKinVW/3KUJ+zA==
#*************** Datasource Related Configurations ***************#
### nacos.plugin.datasource.log.enabled=true

spring.sql.init.platform=postgresql
## Count of DB:
# 数据库连接数量配置
db.num=1
db.url.0=jdbc:postgresql://192.168.0.109:5432/mydatabase?tcpKeepAlive=true&reWriteBatchedInserts=true
db.user.0=myuser
db.password.0=mysecretpassword
# 连接池配置 (使用HikariCP)
db.pool.config.connectionTimeout=30000
db.pool.config.validationTimeout=10000
db.pool.config.maximumPoolSize=20
db.pool.config.minimumIdle=2
db.pool.config.driverClassName=org.postgresql.Driver

五、启动nacos服务

进入nacos\distribution\target\nacos-server-3.1.1\nacos\bin目录，
执行startup.cmd -m=standalone，如下：
