Docker环境下Nacos使用MySQL存储

Posted 2021-09-13 Corwien

1、Docker下载镜像

docker pull nacos/nacos-server

笔者下载时已经到1.3.2 其中mysqljar已经更新至8.0.16

2、创建数据库

create database nacos_config

https://github.com/alibaba/na...

复制sql并执行

3、创建Nacos容器

docker run -d \\
-e PREFER_HOST_MODE=hostname \\
-e MODE=standalone \\
-e SPRING_DATASOURCE_PLATFORM=mysql \\
-e MYSQL_MASTER_SERVICE_HOST=数据库ip \\
-e MYSQL_MASTER_SERVICE_PORT=数据库端口 \\
-e MYSQL_MASTER_SERVICE_USER=用户名 \\
-e MYSQL_MASTER_SERVICE_PASSWORD=密码 \\
-e MYSQL_MASTER_SERVICE_DB_NAME=对应的数据库名 \\
-e MYSQL_SLAVE_SERVICE_HOST=从数据库ip \\
-p 8848:8848 \\
--name nacos-sa-mysql \\
--restart=always \\
nacos/nacos-server

4、修改容器

docker exec -it nacos bash
#进入nacos容器：
docker exec -it nacos bash 
#进入conf文件夹
cd conf
#修改配置参数
vim application.properties

# spring
server.servlet.contextPath=${SERVER_SERVLET_CONTEXTPATH:/nacos}
server.contextPath=/nacos
server.port=${NACOS_APPLICATION_PORT:8848}
spring.datasource.platform=${SPRING_DATASOURCE_PLATFORM:mysql}
nacos.cmdb.dumpTaskInterval=3600
nacos.cmdb.eventTaskInterval=10
nacos.cmdb.labelTaskInterval=300
nacos.cmdb.loadDataAtStart=false
db.num=${MYSQL_DATABASE_NUM:1}
db.url.0=jdbc:mysql://${MYSQL_SERVICE_HOST:mysql地址}:${MYSQL_SERVICE_PORT:端口}/${MYSQL_SERVICE_DB_NAME:数据库名}?serverTimezone=GMT%2B8&characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
#db.url.1=jdbc:mysql://${MYSQL_SERVICE_HOST}:${MYSQL_SERVICE_PORT:3306}/${MYSQL_SERVICE_DB_NAME}?serverTimezone=GMT%2B8&characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.user=${MYSQL_SERVICE_USER:oam}
db.password=${MYSQL_SERVICE_PASSWORD:Ssl_qjy&^986_}
### 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}

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=/,/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
