通过实现MySQL数据库镜像(复制)，可以远程实时备份MySQL数据库。这样如果主机出现故障，或者主机帐号被封，都能迅速切换zencart网店到新的服务器上。
数据库镜像，需要两台服务器(或者用两台VPS主机)。一台为主服务器，另一台为从服务器，所有主服务器上数据库的变化，都实时镜像到从服务器上。
1. 在主服务器上，创建用于数据库镜像的数据库用户，从服务器用这个帐号连接主服务器。
该数据库用户可以是任何数据库用户，只要有REPLICATION SLAVE权限，由于该用户名、密码将明文保存在master.info文件中，因此建议创建、使用单独的镜像用户。

pyqx是使用Python和PyQt开发的多平台图形编辑器。 它专注于Pixel Art，带来了易于使用，用户友好的界面，您将在几分钟之内适应该界面。 如果没有，您可以随时更改！
假设您将使用图形输入板进行绘制，会带来pyqx 。 如果您没有鼠标，请不要担心，因为快捷键和控件的设计很好，也可以使您在使用鼠标时感到舒适。 使用pyqx的最方便方法是，一只手始终放在键盘上，而另一只手每次都用鼠标/笔使用。 您不必每次想更改绘图工具时都动一下手指：已经考虑过了。

在做一个需要用到echarts地图的项目的时候，成功通过ajax获取到了后台提供的数据，并生成了想要的JSON串。但是，放到echarts option.series[0].data里，获取不到数据。在生成的地图上无法看到你从后台获取到的值。翻遍百度和必应，给出的答案五花八门，仍旧未解决问题，最后还是一个同事大牛给解决的，在此分享给大家。希望对大家有帮助，，，，
废话不多说，直接上码：
$(function () {
var data = [];
function setOption(data){
var myChart = echarts.init(document.getElementB
