mysqldump数据库同步遇到的问题

1、同步数据是遇到 没有 lock database权限，报 “ mysqldump: Got error: 1044: Access denied for user 'spider_data'@'121.201.10.2' to database 'db_rankapp' when doing LOCK TABLES” 错误

在mysqldump参数上加上 “ --single-transaction” 参数即可

参考文档：

2、同步时遇到 mysqldump 版本跟线上mysql不一致，报“mysqldump: Couldn't execute 'SET OPTION SQL_QUOTE_SHOW_CREATE=1':”错误

我的同步脚本如下，放在crontab里执行：

#/bin/bash
#同步appannie爬虫在腾讯云爬取的排行榜收入下载数据
set -x 

PATH=$PATH:/usr/local/bin
export PATH

db_option="--replace -c --add-drop-table=false --no-create-db --no-create-info --skip-tz-utc --single-transaction"
db_option2="--single-transaction"
character="--default-character-set=utf8"

day=`date +%Y-%m-%d`
echo $day
