Docker如何安装nacos最新版本2.2.0

墨蓝 2024-03-30 15:04 17阅读 0赞

本文介绍如何在docker容器下安装部署nacos最新版本2.2.0。

### 一、单机本地配置 ###

#### 1.1 拉取nacos镜像 ####

执行以下命令从docker远端拉取nacos镜像文件。

docker pull nacos/nacos-server

#### 1.2 启动nacos镜像 ####

执行以下命令，以单机模式启动nacos镜像。

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

#### 1.3 验证nacos是否启动成功 ####

执行以下命令，查看容器是否启动成功。

docker ps -a

#### 1.4 访问nacos管理页面 ####

至此，nacos服务已经成功启动，通过访问地址:http:XXXX//:8848/nacos打开管理端页面。默认账号：nacos，密码：nacos。

### 二、单机模式支持mysql ###

通过以上方式是可以简单快捷的启动并使用nacos了，但nacos中的所有数据都会保存在容器内部。倘若容器迁移则nacos源数据则不复存在，所以通常我们通常会将nacos的数据保存在mysql中。

#### 2.1 准备mysql数据库 ####

mysql数据库的版本要求：5.6.5+。推荐5.7版本。安装好mysql数据库后，创建表nacos\_config。

#### **2.2 初始化数据库nacos\_config** ####

在nacos的安装文件夹conf目下，找到nacos-mysql.[sql脚本][sql]，然后执行数据库初始化。脚本内容如下，不需要任何修改，直接复制粘贴运行就可以了。

找到配置文件的如下内容处，取消掉前边的注释\#标识，同时修改数据库配置信息为自己的实际配置信息，主要是修改数据库访问账号和密码。

#### 2.4 运行nacos镜像 ####

执行以下命令运行nacos镜像，同时映射本地配置文件。

docker run -d -e MODE=standalone -e PREFER_HOST_MODE=hostname -e JVM_XMS=256m -e JVM_XMX=256m -p 8848:8848 -p 7848:7848 -p 9848:9848 -p 9849:9849 -v /mnt/docker_data/nacos/conf/application.properties:/home/nacos/conf/application.properties --name nacos nacos/nacos-server

#### 2.5 测试验证 ####

在浏览器中打开[http://XXXX:8848/nacos][http_XXXX_8848_nacos]打开nacos管理页面，在配置管理-配置列表添加配置信息。添加完毕后，打开mysql数据库中的config\_info表，如果表中保存了新添加的配置信息，说明配置成功，数据保存到数据库了。
