庭中三千梨花树,再无一朵入我心。 心中只你一朵,似在心中,不在心中,可望可念可想不可及。

单节点容器使用外置数据库实战

一、编辑docker-compose

1.创建nacos目录

mkdir nacos
cd nacos

2.编写docker-compose

version: "3.8"
services:
  nacos:
    image: nacos/nacos-server:v2.0.4
    container_name: nacos
    env_file:
      - ./env/nacos-standlone-mysql.env
    volumes:
      - ./standalone-logs/:/home/nacos/logs
      - ./conf/application.properties:/home/nacos/conf/application.properties
      - ./init.d/custom.properties:/home/nacos/init.d/custom.properties
    ports:
      - "8848:8848"
      - "9848:9848"
      - "9555:9555"
    restart: always

2、根据dockerfile和配置文件配置变量文件

1.Dockerfile

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


### The token expiration in seconds:
nacos.core.auth.default.token.expire.seconds=${NACOS_AUTH_TOKEN_EXPIRE_SECONDS:18000}

### The default token:
nacos.core.auth.default.token.secret.key=${NACOS_AUTH_TOKEN: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=${NACOS_AUTH_CACHE_ENABLE:false}
nacos.core.auth.enable.userAgentAuthWhite=${NACOS_AUTH_USER_AGENT_AUTH_WHITE_ENABLE:false}

### turn off security

4.编写nacos-standlone-mysql.env

mkdir env
cd env
vim nacos-standlone-mysql.env

PREFER_HOST_MODE=ip
MODE=standalone
SPRING_DATASOURCE_PLATFORM=mysql

5.编写配置文件

mkdir conf
vim application.properties

server.servlet.contextPath=/nacos
server.port=8848
db.pool.config.connectionTimeout=30000
db.pool.config.validationTimeout=10000
db.pool.config.maximumPoolSize=20
db.pool.config.minimumIdle=2

spring.datasource.platform=mysql

db.num=1
db.url.0=jdbc:mysql://172.16.0.*:3306/nacos?serverTimezone=GMT%2B8&characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false&useUnicode=true
db.user.0=nacos
db.password.0=nacos

nacos.naming.empty-service.auto-clean=true
nacos.naming.empty-service.clean.initial-delay-ms=50000
nacos.naming.empty-service.clean.period-time-ms=30000
management.metrics.export.elastic.enabled=false
management.metrics.export.influx.enabled=false
server.tomcat.accesslog.enabled=true
server.tomcat.accesslog.pattern=%h %l %u %t "%r" %s %b %D %{User-Agent}i %{Request-Source}i
server.tomcat.basedir=
nacos.security.ignore.urls=/,/error,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-ui/public/**,/v1/auth/**,/v1/console/health/**,/actuator/**,/v1/console/server/**
nacos.core.auth.system.type=nacos
nacos.core.auth.enabled=false
nacos.core.auth.default.token.expire.seconds=18000
nacos.core.auth.default.token.secret.key=SecretKey012345678901234567890123456789012345678901234567890123456789
nacos.core.auth.caching.enabled=true
nacos.core.auth.enable.userAgentAuthWhite=false
nacos.core.auth.server.identity.key=serverIdentity
nacos.core.auth.server.identity.value=security
nacos.istio.mcp.server.enabled=false

3、创建数据库

1.创建数据库

create database nacos charset utf8mb4 collate utf8mb4_bin;

导入数据库初始化文件

2.创建用户并授权

create user nacos@'%' identified with mysql_native_password  by 'nacos';
grant all on nacos.* to nacos@'%';

flush privileges;

4、启动nacos

docker-compose up -d
