ES cerebro plug, X-pack plug-in installation
Cerebro plugin is a very useful plugin for monitoring es cluster. With this plugin we can see the details of the ES cluster, index creation and so on. Because the ES itself does not have its own management. Therefore, it must be using the appropriate API to manage and maintain. So we talk about this plugin and install the following common operations today.
First of all: Environmental ready Cloud Hosting ES 6.8.x
Second: ES Cluster of three nodes in a cluster (cluster build another concern Bowen)
Step Three: Download cerebro plugin download at the following address
https://github.com/lmenezes/cerebro/releases
The fourth step: installing, configuring plug-cerebro
Step Five: In general, start the service directly after we unpacked the directory, you can, but because of their own this plug-in is installed in the cloud server, because our cloud servers have multiple IP's. We need direct access to the outside under the net plug, turn the ES operation. So we need to modify the configuration file. Configuration is as follows:
application.conf modify configuration files in the installation directory
Change the default 127.0.0.1 0.0.0.0
Then save and exit, start cerebro plug-in service after the service starts successfully, it will start a 9000 port.
After the start-ok 9000 port
So we have a browser to access it;
In the node address we casually enter a node information. Then click connect. To enter the following interface.
After entering the main interface, displays the information of the cluster, such as node information, index information, fragment information,
We can also create your own index information.
Next, we look at the installation of x-pack insert.
X-pack是Elasticsearch的一个商业版扩展包，将安全，警告，监视，图形和报告功能捆绑在一个易于安装的软件包中。它可以作为插件被快速集成在Kibana中，并提供给用户集群启用认证、角色权限管控、集群实时监控、可视化报表生成、机器学习等能力。它是收费的插件，但是有一个功能是免费的，那就是它的Monitoring监控功能。
X-pack Monitoring 具备ES集群的监控功能，能够及时的对ES集群进行监控、及时有效的关注ES集群状态的变化。是一个很好的运维插件。下面我们讲一下它的安装。
首先：停掉ES服务。然后进入ES安装目录。$PATH/bin/elastisearch-plugin install x-pack
其次：进入kibana安装目录。$PATH/bin/kibana-plugin install x-pack
再次，重启es kibana服务。这里要说明一下。原来这个Kibana都不具备这个功能，新版本应该是ES 6.X 后，此插件基本都集成在了这个ES、Kibana软件中。原来是独立需要安装的。
于是我们打开kibana的主界面看看。左边菜单栏--monitor功能。
就会有各种图示信息，如下所示
这个还是需要大家多去了解了解拉，好啦就这样了。非常不错，大家操作一下。
