nacos从1.x升级到2.4.3问题记录

article 2025/1/15 7:22:19

从dockerhup拉镜像

docker pull nacos/nacos-server:latest

创建宿主机数据目录


##存放数据，日志，配置文件的目录，为什么要挂载，想想如果是mysql
##不挂载持久化数据到宿主机，重启数据都没了，这跟删库有啥区别
mkdir -p /Applications/java_dev_util/dockerData/nacos/logs
mkdir -p /Applications/java_dev_util/dockerData/nacos/data
mkdir -p /Applications/java_dev_util/dockerData/nacos/config

#授权一下，不然没权限往宿主机目录同步数据
chmod o+rwx -R /Applications/java_dev_util/dockerData/nacos/logs
chmod o+rwx -R /Applications/java_dev_util/dockerData/nacos/data
chmod o+rwx -R /Applications/java_dev_util/dockerData/nacos/config

#在config目录下创建application.properties文件(也可以启动容器后从容器中复制(docker cp命令)出来),内容如下：
# 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=${TOMCAT_ACCESSLOG_ENABLED:false}
server.error.include-message=ALWAYS
# default current work dir
server.tomcat.basedir=file:.
#*************** Config Module Related Configurations ***************#
### Deprecated configuration property, it is recommended to use `spring.sql.init.platform` replaced.
#spring.datasource.platform=${SPRING_DATASOURCE_PLATFORM:}
spring.sql.init.platform=${SPRING_DATASOURCE_PLATFORM:}
nacos.cmdb.dumpTaskInterval=3600
nacos.cmdb.eventTaskInterval=10
nacos.cmdb.labelTaskInterval=300
nacos.cmdb.loadDataAtStart=false
db.num=${MYSQL_DATABASE_NUM:1}
db.url.0=jdbc:mysql://${MYSQL_SERVICE_HOST}:${MYSQL_SERVICE_PORT:3306}/${MYSQL_SERVICE_DB_NAME}?${MYSQL_SERVICE_DB_PARAM:characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false}
db.user.0=${MYSQL_SERVICE_USER}
db.password.0=${MYSQL_SERVICE_PASSWORD}
## DB connection pool settings
db.pool.config.connectionTimeout=${DB_POOL_CONNECTION_TIMEOUT:30000}
db.pool.config.validationTimeout=10000
db.pool.config.maximumPoolSize=20
db.pool.config.minimumIdle=2
### The auth system to use, currently only 'nacos' and 'ldap' is supported:
nacos.core.auth.system.type=${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=${NACOS_AUTH_CACHE_ENABLE:false}
nacos.core.auth.enable.userAgentAuthWhite=${NACOS_AUTH_USER_AGENT_AUTH_WHITE_ENABLE:false}
nacos.core.auth.server.identity.key=${NACOS_AUTH_IDENTITY_KEY:}
nacos.core.auth.server.identity.value=${NACOS_AUTH_IDENTITY_VALUE:}
## spring security config
### turn off security
nacos.security.ignore.urls=${NACOS_SECURITY_IGNORE_URLS:/,/error,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/v1/auth/**,/v1/console/health/**,/actuator/**,/v1/console/server/**}
# metrics for elastic search
management.metrics.export.elastic.enabled=false
management.metrics.export.influx.enabled=false
nacos.naming.distro.taskDispatchThreadCount=10
nacos.naming.distro.taskDispatchPeriod=200
nacos.naming.distro.batchSyncKeyCount=1000
nacos.naming.distro.initDataRatio=0.9
nacos.naming.distro.syncRetryDelay=5000
nacos.naming.data.warmup=true
nacos.console.ui.enabled=true
nacos.core.param.check.enabled=true

启动容器

docker run -it --name nacos -p 8848:8848 --restart=always -e MODE=standalone \
-v /Applications/java_dev_util/dockerData/nacos/logs:/home/nacos/logs \
-v /Applications/java_dev_util/dockerData/nacos/data:/home/nacos/data \
-v //Applications/java_dev_util/dockerData/nacos/conf/application.properties:/home/nacos/conf/application.properties \
-d nacos/nacos-server:latest

验证是否启动成功，命令行docker logs nacos 或者 localhost:8848/nacos

nacos2.4.3默认不需要密码登录的，如需要开启鉴权，修改application.properties配置文件里面对应的选项即可，如：

nacos.core.auth.enabled=true
nacos.core.auth.caching.enabled=true
nacos.core.auth.enable.userAgentAuthWhite=false
nacos.core.auth.server.identity.key=nacos
nacos.core.auth.server.identity.value=nacos

集成到项目中，这里是在父pom文件里做版本统一管理，同时注意springboot版本要与springcloud版本对应，父pom文件

application-local.yml文件配置：

        name: content

    #nacos
    cloud:

                server-addr: localhost:8848
                import-check:
                    enabled: false
            discovery:
                server-addr: localhost:8848

此时启动项目发现会报错
在这里插入图片描述
原因是：nacos 2.x版本，新增了两个端口。这两个端口在nacos原先的端口上(默认8848)，进行一定偏移量自动生成。

9848	1000	客户端gRPC请求服务端端口，用于客户端向服务端发起连接和请求
9849	1001	服务端gRPC请求服务端端口，用于服务间同步等

此时只需要在docker启动时同时指定相应的端口即可

#删除正在运行的nacos
docker rm -f nacos

#重启
docker run -it --name nacos -p 8848:8848 -p 9848:9848 -p 9849:9849 --restart=always -e MODE=standalone \
-v /Applications/java_dev_util/dockerData/nacos/logs:/home/nacos/logs \
-v /Applications/java_dev_util/dockerData/nacos/data:/home/nacos/data \
-v //Applications/java_dev_util/dockerData/nacos/conf/application.properties:/home/nacos/conf/application.properties \

现在端口都映射了
在这里插入图片描述
再次启动项目，发现报另外一个错：java.lang.IllegalArgumentException: Param ‘serviceName’ is illegal, serviceName is blank
在这里插入图片描述
在yml文件中显式指定服务名称
在这里插入图片描述
我看网上还有的人说是discovery.service没有设置，按理说这个不用设置，点进去会发现他默认就是取的${spring.application.name}，这不知道是不是官方的一个bug，但显式指定后发现跑起来确实没报错，服务也能正常注册发现
