Jedis测试异常：connect timed out

Jedis 测试时出现了一个问题，在网上找了好久才解决问题，原来是虚拟机防火墙的问题。问题如下：

关闭VMware防火墙：

# service firewalld stop

关闭centos7的防火墙：

# systemctl stop firewalld.service #停止firewall## systemctl disable firewalld.service #禁止firewall开机启动# # firewall-cmd --state #查看默认防火墙状态（关闭后显示notrunning，开启后显示running）
