使用docker容器启动一个nacos
1. 先拉取一个nacos镜像;
docker pull nacos/nacos-server;
如果指定哪个版本则 docker pull nacos/nacos-server:1.2.1;
如果是arm版本 docker pull zhusaidong/nacos-server-m1:2.0.3 或 docker pull zill057/nacos-server-apple-silicon:2.0.3
2. 查看镜像
docker images
挂载目录
mkdir -p /usr/local/docker/nacos/logs/ #新建logs目录
mkdir -p /usr/local/docker/nacos/conf/ #新建conf目录
启动一个容器用于复制配置文件到挂载目录
docker run -p 8848:8848 --name nacos -d nacos/nacos-server:1.2.1
如果容器启动失败找不到占位符直接在宿主机/nacos/conf下创建文件application.properties配置文件即可
server.servlet.contextPath=/nacos server.error.include-message=ON_PARAM server.port=8848 spring.datasource.platform=mysql db.num=1 db.url.0=jdbc:mysql://localhost:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC db.user.0=root db.password.0=root db.pool.config.connectionTimeout=30000 db.pool.config.validationTimeout=10000 db.pool.config.maximumPoolSize=20 db.pool.config.minimumIdle=2 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=file:. 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.caching.enabled=true nacos.core.auth.enable.userAgentAuthWhite=false nacos.core.auth.server.identity.key=serverIdentity nacos.core.auth.server.identity.value=security nacos.core.auth.plugin.nacos.token.expire.seconds=18000 nacos.core.auth.plugin.nacos.token.secret.key=SecretKey012345678901234567890123456789012345678901234567890123456789 nacos.istio.mcp.server.enabled=false
复制
docker cp nacos:/home/nacos/logs/ /usr/local/docker/nacos/
docker cp nacos:/home/nacos/conf/ /usr/local/docker/nacos/
删除容器
docker rm -f nacos
配置mysql地址(不配置默认用容器自带的销毁就没了)
vim /usr/local/docker/nacos/conf/application.properties
spring.datasource.platform=mysql db.num=1 db.url=jdbc:mysql://localhost:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=30000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC db.user=root db.password=123456
在mysql中创建nacos需要的表 nacos_config
启动nacos (privileged=true将容器内的权限变为root权限)
-p如果服务使用了多个端口,并且希望它们都能从宿主机上访问,需要为每个端口指定一个映射。如果是nacos.2.x版本需要开放以下端口
-p 7848:7848 \
-p 9848:9848 \
-p 9849:9849 \
docker run --name nacos-server \
-p 8848:8848 \
--privileged=true \
--restart=always \
-e JVM_XMS=256m \
-e JVM_XMX=256m \
-e MODE=standalone \
-e PREFER_HOST_MODE=hostname \
-v /usr/local/docker/nacos/logs:/home/nacos/logs \
-v /usr/local/docker/nacos/conf/application.properties:/home/nacos/conf/application.properties \
-d nacos/nacos-server:1.4.1
启动成功查看配置是否正确
## 进入到nacos容器里 docker exec -it nacos /bin/bash ## 查看application.properties文件 cat /home/nacos/conf/application.properties ## 退出容器 exit
快速简版不需要挂载
docker run --env MODE=standalone --name mynacos -d -p 8848:8848 nacos/nacos-server:1.2.1;
查看日志
docker logs -f mynacos
访问nacos
虚拟机ip:8848/nacos/index.html
登陆nacos 账号:nacos 密码: nacos
