docker run -d --name nacos -p 8848:8848 -p 9848:9848 -p 9849:9849  --restart=always -e JVM_XMS=256m -e JVM_XMX=256m -e MODE=standalone -e SPRING_DATASOURCE_PLATFORM=mysql  -e MYSQL_SERVICE_HOST=192.168.1.123 -e MYSQL_SERVICE_PORT=3306 -e MYSQL_SERVICE_DB_NAME=ry-config -e MYSQL_SERVICE_USER=root -e MYSQL_SERVICE_PASSWORD=mysql2017 -e MYSQL_SERVICE_DB_PARAM="characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC" nacos/nacos-server
