Docker启动Nacos2.4.3并且使用MySQL

1.拉取容器

复制代码

docker pull nacos/nacos-server:v2.4.3

2.创建宿主机挂载目录

复制代码

mkdir -p /docker/nacos/logs/
mkdir -p /docker/nacos/conf/

3.启动临时容器并拷贝配置文件

启动临时容器

复制代码

docker run -d --name nacos-temp -p 8848:8848 nacos/nacos-server:v2.4.3

拷贝Nacos配置

复制代码

docker cp nacos-temp:/home/nacos/logs/ /data/nacos/
docker cp nacos-temp:/home/nacos/conf/ /data/nacos/

移除临时容器

复制代码

docker rm -f nacos-temp

4.查看宿主机的conf的application.properties配置文件是如下:

复制代码

# spring
server.servlet.contextPath=${SERVER_SERVLET_CONTEXTPATH:/nacos}
server.contextPath=/nacos
server.port=${NACOS_APPLICATION_PORT:8848}
server.tomcat.accesslog.max-days=30
server.tomcat.accesslog.pattern=%h %l %u %t "%r" %s %b %D %{User-Agent}i %{Request-Source}i
server.tomcat.accesslog.enabled=${TOMCAT_ACCESSLOG_ENABLED:false}
server.error.include-message=ALWAYS
# default current work dir
server.tomcat.basedir=file:.
#*************** Config Module Related Configurations ***************#
### Deprecated configuration property, it is recommended to use `spring.sql.init.platform` replaced.

db.user.0=${MYSQL_SERVICE_USER}
db.password.0=${MYSQL_SERVICE_PASSWORD}
## DB connection pool settings
db.pool.config.connectionTimeout=${DB_POOL_CONNECTION_TIMEOUT:30000}
db.pool.config.validationTimeout=10000

### The auth system to use, currently only 'nacos' and 'ldap' is supported:
nacos.core.auth.system.type=${NACOS_AUTH_SYSTEM_TYPE:nacos}
### worked when nacos.core.auth.system.type=nacos
### The token expiration in seconds:
nacos.core.auth.plugin.nacos.token.expire.seconds=${NACOS_AUTH_TOKEN_EXPIRE_SECONDS:18000}
### The default token:
nacos.core.auth.plugin.nacos.token.secret.key=${NACOS_AUTH_TOKEN:}
### Turn on/off caching of auth information. By turning on this switch, the update of auth information would have a 15 seconds delay.
nacos.core.auth.caching.enabled=${NACOS_AUTH_CACHE_ENABLE:false}

5.启动容器的docker-compose.yml也可转换成docker run 命令如下代码(运行前需要把application.properties):

复制代码

version: '3'
services:
  nacos:
    image: nacos/nacos-server:v2.4.3
    container_name: nacos
    environment:
      - MODE=standalone
      - SPRING_DATASOURCE_PLATFORM=mysql
      - MYSQL_SERVICE_HOST=mysql8
      - MYSQL_SERVICE_PORT=3306
      - MYSQL_SERVICE_DB_NAME=default_nacos
      - MYSQL_SERVICE_USER=root
      - MYSQL_SERVICE_PASSWORD=root
      - MYSQL_SERVICE_DB_PARAM=characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=GMT%2B8
    ports:
      - "8848:8848"
      - "9848:9848"
      - "9849:9849"
    volumes:
      - ./logs/:/home/nacos/logs
      - ./conf/:/home/nacos/conf
    restart: always
    networks:
      - cluster1
networks:
  cluster1:
    external: true

注:以上Nacos使用的MySQL是另外一个已启动的容器,两容器是在一个宿主机上,且在同一网络下

额外创建网络命令如下:

复制代码

docker network create [自己定义的网络名称] 创建新网络网络驱动使用docker默认的
docker network ls 查看网络，看是否创建成功

//连接到创建的网络
docker network connect [自己定义的网络名称] [mysql的id]
docker network connect [自己定义的网络名称] [nacos的id]

//查看两容器是否在创建的网络中
docker network inspect [自己定义的网络名称]
