Elastic Stack学习--elasticsearch安装X-Pack

x-pack作为elasticsearch的增强组件，主要提供安全、监控等功能。elasticsearch安装x-pack组件的顺序如下图： 离线安装x-pack 因为大多数情况下，生产环境中的服务器无法访问到外网环境，因此，使用离线安装方式；在线安装方式见参考连接；1）下载离线安装包，并上传至服务器；（集群中每个elasticsearch节点都要执行） 注：x-pack离线安装包包含elasticsearch、logstash、kibana中所需组件，可以共用； 2）执行安装命令；（集群中每个elasticsearch节点都要执行） bin/elasticsearch-plugin install file:///path/to/file/x-pack-6.2.2.zip 注：此处的安装包路径一定是绝对路径，直接使用压缩包安装即可，无需解压；格式类似：file://路径 安装成功后结果类似如下： current workdir: /home/work/elasticsearch-6.2.2 -> Downloading file:///home/work/x-pack-6.2.2.zip [=================================================] 100%?? @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: plugin requires additional permissions @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ * java.io.FilePermission \\.\pipe\* read,write * java.lang.RuntimePermission accessClassInPackage.com.sun.activation.registries * java.lang.RuntimePermission getClassLoader * java.lang.RuntimePermission setContextClassLoader * java.lang.RuntimePermission setFactory * java.net.SocketPermission * connect,accept,resolve * java.security.SecurityPermission createPolicy.JavaPolicy * java.security.SecurityPermission getPolicy * java.security.SecurityPermission putProviderProperty.BC * java.security.SecurityPermission setPolicy * java.util.PropertyPermission * read,write See http://docs.oracle.com/javase/8/docs/technotes/guides/security/permissions.html for descriptions of what these permissions allow and the associated risks.

learning功能，则可以在elasticsearch.yml中设置禁用： xpack.ml.enabled: false 解决办法2：安装或者升级glibc；如果使用centos4.3版本，则果断升级操作系统； 参考官方论坛 如何修改临时文件目录 elasticsearch以及x-pack插件的运行，依赖于ES_TMPDIR环境变量的值作为临时文件目录；如果未设置，则默认为/tmp/elasticsearch;可通过在.bashrc或者.bash_profile文件中添加环境变量显式设置临时文件目录： export ES_HOME=/home/work/elasticsearch-6.2.2 export ES_TMPDIR="${ES_HOME}/tmp"
