添加初始化容器

docker run -d --name nacos \
  -p 8848:8848 -p 9848:9848 -p 9849:9849 \
  -e MODE=standalone \
  nacos/nacos-server:v2.5.1

创建挂载目录：首先在宿主机上创建用于存放配置、日志和数据的目录。

mkdir -p /home/tools/nacos/{conf,logs,data}

复制配置文件和日志文件

docker cp nacos:/home/nacos/conf /home/tools/nacos/
docker cp nacos:/home/nacos/logs /home/tools/nacos/
docker cp nacos:/home/nacos/data /home/tools/nacos/

停止并删除临时容器

docker rm -f nacos

挂载目录运行

执行命令  

openssl rand -base64 32 

 获取新的base64的字符串替换token

docker run -d \
  --name nacos \
  -p 8848:8848 -p 9848:9848 -p 9849:9849 \
  -v /home/tools/nacos/conf:/home/nacos/conf \
  -v /home/tools/nacos/logs:/home/nacos/logs \
  -v /home/tools/nacos/data:/home/nacos/data \
  -e MODE=standalone \
  -e JVM_XMS=256m \
  -e JVM_XMX=256m \
  -e NACOS_AUTH_ENABLE=true \
  -e NACOS_AUTH_TOKEN="xhPY+6DAQP3eZNk7jCEkOagvxy2fakA1ahlzhWX4cjA=" \
  -e NACOS_AUTH_IDENTITY_KEY=nacosNodeId \
  -e NACOS_AUTH_IDENTITY_VALUE=J8fH3sK9pLq2ZrT7wY5xQeA12 \
  --restart=always \
  nacos/nacos-server:v2.5.1

注意：在数据库连接字符串（如配置文件中）或相关环境变量里，数据库的IP地址不要使用 localhost或 127.0.0.1，因为这在容器内指向的是容器自身而非宿主机上的MySQL服务。应使用宿主机的真实IP地址或能从容器的网络访问到的地址
