spring-cloud-alibaba nacos配置中心使用

安装(基于docker)

docker

docker run --name nacos -e MODE=standalone -p 8848:8848 -d nacos/nacos-server:1.4.1

上面只是将nacos安装启动，如果不小心将启动的容器删除了，那么之前操作过的所有内容都会被删除，为了以防这种事情发生我们可以将数据持久化存在磁盘里，就是用下面的方法

创建mysql表
MySQL创建

创建配置文件
路径/opt/nacos/conf/application.properties

# spring
server.servlet.contextPath=${SERVER_SERVLET_CONTEXTPATH:/nacos}
server.contextPath=/nacos
server.port=${NACOS_APPLICATION_PORT:8848}
spring.datasource.platform=${SPRING_DATASOURCE_PLATFORM:""}
nacos.cmdb.dumpTaskInterval=3600
nacos.cmdb.eventTaskInterval=10
nacos.cmdb.labelTaskInterval=300
nacos.cmdb.loadDataAtStart=false
#修改user\passowrd\url
db.num=1
db.url.0=jdbc:mysql://host:3306/nacos?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC&allowMultiQueries=true
db.user=username
db.password=userpassowrd
### The auth system to use, currently only 'nacos' is supported:
nacos.core.auth.system.type=${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}
nacos.core.auth.server.identity.key=${NACOS_AUTH_IDENTITY_KEY:serverIdentity}
nacos.core.auth.server.identity.value=${NACOS_AUTH_IDENTITY_VALUE:security}
server.tomcat.accesslog.enabled=${TOMCAT_ACCESSLOG_ENABLED:false}
server.tomcat.accesslog.pattern=%h %l %u %t "%r" %s %b %D
# default current work dir
server.tomcat.basedir=
## spring security config
### turn off security
nacos.security.ignore.urls=${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

docker + mysql

docker run --name nacos -d -p 8848:8848 --privileged=true --restart=always -e JVM_XMS=256m -e JVM_XMX=256m -e MODE=standalone -e PREFER_HOST_MODE=hostname -v /opt/nacos/logs:/home/nacos/logs -e SPRING_DATASOURCE_PLATFORM=mysql -v /opt/nacos/conf/application.properties:/home/nacos/conf/application.properties -v /opt/nacos/data:/home/nacos/data nacos/nacos-server:1.4.1

操作完成后直接访问http:host:port/nacos 默认账号密码是nacos/nacos

进入UI界面就可以进行操作了



新建完配置后再项目中稍微再配置一下，配置必须写在bootstrap.properties中

将配置内容注入即可使用
