Docker部署 Nacos超详细步骤（单机版）

移动开发 2023-09-03 10:31:05 阅读次数: 0

我这里用的是nacos1.1.3，2.0以上略有不同下面会注释

1、安装并运行mysql

我这里nacos数据库使用mysql

docker run -p 3306:3306 --name mysql \
-v /mydata/mysql/log:/var/log/mysql \
-v /mydata/mysql/data:/var/lib/mysql \
-v /mydata/mysql/conf:/etc/mysql \
-e MYSQL_ROOT_PASSWORD=root \
-d mysql:5.7
# --name指定容器名字 -v目录挂载 -p指定端口映射  -e设置mysql参数 -d后台运行

新建数据库nacos，导入数据库sql文件

#sql下载地址
https://github.com/alibaba/nacos/blob/master/distribution/conf/nacos-mysql.sql

2、安装nacos

#不写版本号则默认拉取最新版本
docker pull nacos/nacos-server:1.1.3

3、运行nacos

3.1 方式一（推荐）

①创建本地映射文件

mkdir -p /mydata/nacos/conf
mkdir -p /mydata/nacos/logs
mkdir -p /mydata/nacos/data

②搭建临时nacos容器

 docker run --name nacos -d -p 8848:8848 -e MODE=standalone  nacos/nacos-server:1.1.3

③从临时容器中复制 Nacos 配置文件

docker cp nacos:/home/nacos/logs/ /mydata/nacos
docker cp nacos:/home/nacos/conf/ /mydata/nacos
docker cp nacos:/home/nacos/data/ /mydata/nacos
#意思是吧nacos容器中的log conf data的数据复制到本机的/mydata/nacos中

④删除临时容器

docker rm -f nacos

⑤修改 Nacos 配置文件 application.properties

vi /mydata/nacos/conf/application.properties

修改数据库信息

spring.datasource.platform=mysql
nacos.cmdb.loadDataAtStart=false
db.num=${MYSQL_DATABASE_NUM:1}
db.url.0=jdbc:mysql://192.168.2.88:3306/nacos?characterEncoding=utf8&connectTimeout=10000&socketTimeout=30000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user=root
db.password=root

注意：修改自己的mysql地址、账号、密码等信息
⑥启动

# 带配置信息的启动
docker run -d \
--name nacos \
-p 8848:8848 \
-e MODE=standalone \
-v /mydata/nacos/logs/:/home/nacos/logs \
-v /mydata/nacos/conf/:/home/nacos/conf \
-v /mydata/nacos/data/:/home/nacos/data \
--restart=always \
nacos/nacos-server:1.1.3

nacos2.0以上版本端口映射必须要加上9848和9849
-p 8848:8848 -p 9848:9848 -p 9849:9849 \

⑦可能得问题
我遇到一个问题一直提示连接超时，拒绝连接之类的错误
解决方法：
先修改数据库url的参数&connectTimeout=10000&socketTimeout=30000
用其他软件连接下这个数据库然后随便查询个啥，最后就发现nacos启动成功了（这可能是低版本nacos的bug，我用高版本没出现过这个问题）
下面是错误代码

3.2 方式二

方式二不挂载本机文件（不推荐）

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