我这里用的是nacos1.1.3,2.0以上略有不同下面会注释
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
#不写版本号则默认拉取最新版本
docker pull nacos/nacos-server:1.1.3
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
