一键部署脚本

实现逻辑：
1、先启动一个nacos临时容器,把sql初始化脚本拷贝出来
2、启动mysql
3、导入sql
4、启动nacos

#! /bin/bash
function getsql() {
    docker run -d --name tmp-nacos  nacos/nacos-server:v2.2.3 && \
    docker cp tmp-nacos:/home/nacos/conf/mysql-schema.sql ./ && \
    docker rm -f tmp-nacos
    echo "从nacos容器中获取初始化sql文件"
}

function startdb() {
    mkdir -p nacos-mysql/conf

    cat > nacos-mysql/conf/my.cnf <<EOF
