lhstack/nacos repository overview

⁠关于nacos2.2.x之后版本配置描述

⁠配置说明

环境变量中增加以下参数，方便以后迭代的版本中更灵活的使用

JVM_*:  如JVM_server_port=8088 ==> java -Dserver.port=8088 -jar x.jar
JVM_*__*: 如JVM_server_error_include__message=always ==> 最终会转换成-Dserver.error.include-message=always
ARG_*: 同JVM_*类似，只是作用于main的args参数,如ARG_server_port=8088 ==> java -jar x.jar --server.port=8088
ARG_*__*: 同JVM_*__*类似，参考ARG_*的作用域即可
JAVA_OPT_EXT: 作用于 java (之间的环境变量，用户可以自由扩展,但是此环境变量的含义实际上是设置外部的classpath) -jar x.jar
JVM_OPTS: 作用于 java (这里定义就是设置jvm的系统参数，用于jvm调优等) $JAVA_OPT_EXT -jar x.jar
NACOS_SERVERS: 这是一个特殊的环境变量，用于设置nacos集群的服务地址,如182.100.100.101 182.100.100.100
# 最终的效果会变成 java ${JVM_OPTS} ${JAVA_OPT_EXT} parsing(${JVM_*...|JVM_*__...}) -jar x.jar parsing(${ARG_*...|ARG_*__...})

⁠下面给出一个集群的demo，如需更深入的配置nacos的参数，请使用者去官网了解，根据这种配置映射模式去设置即可

⁠.env

#true为单机，false为集群 ==> -Dnacos.standalone=xxx
JVM_nacos_standalone="false"
#数据库类型 -Dspring.datasource.platform
JVM_spring_datasource_platform="mysql"
NACOS_SERVERS="182.100.100.101 182.100.100.100"
# 是否开启身份验证 ==> -Dnacos.core.auth.enabled=xxx
JVM_nacos_core_auth_enabled='"true"'
# ==> --management.endpoints.web.exposure.include='*'
ARG_management_endpoints_web_exposure_include='"*"'
ARG_db_url_0='"jdbc:mysql://10.43.33.6:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC"'
ARG_db_num='"1"'
JVM_OPTS="-Xmx512m -Xms512m -XX:+UseG1GC"
JVM_db_user_0="root"
JVM_db_password_0="123456"

⁠以下内容只作用于nacos2.2.x之前我构建的镜像版本，请注意区分

⁠配置同nacos官方相同

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

⁠单机启动

注意，如果使用的是nacos2.x的版本，请在运行命令中暴露9848端口，9848端口为grpc交互端口，在最新的客户端中，是使用grpc作为协议交互

⁠docker-compose

集群部署

init目录中放nacos.sql文件，mysql在创建的过程中会初始化nacos数据库,开头加入两条sql
CREATE DATABASE `nacos` CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
USE `nacos`;
