通过zookeeper搭建dubbo注册中心遇到的问题:
在linux下安装,配置并启动zookeeper。
在window环境下启动服务提供方时,未成功启动,报以下错误:

检查之后发现两个问题:
1. zookeeper的服务没有开启
执行./zkServer.sh start
2. 访问不到zookeeper中心是因为 需要关闭防火墙:service iptables stop 否则访问不到2181端口
连接数据库时报错信息如下: Unknown system variable 'language'
上网查了问题大部分都说是jdbc驱动和mysql版本不匹配,于是将maven中mysql的版本调整
mysql-connector-java的jar包不匹配,原来是mysql-connector-java-5.1.36.jar,换成mysql-connector-java-5.1.6.jar之后连接成功
