Tip: 由于网络原因，有时一次可能安装不成功，所以可以多试两次
重启ES服务
安装后得重启，否则不会生效，如果是一个集群，那每一个节点安装完插件后都得重启
代码语言：javascript复制The plugin must be installed on every node in the cluster, and each node must be restarted after installation.
[root@esdbqp bin]# /etc/init.d/elasticsearch restart
Stopping elasticsearch: [ OK ]
Starting elasticsearch: [ OK ]
[root@esdbqp bin]#Note: 一定得重启
