**安装运行**

**1、前置安装java8**

jdk-8u112-linux-x64.rpm

下载地址：http://www.oracle.com/technetwork/java/javase/downloads/index.html

**2、下载**

wgethttps://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.1.1.zip

**3、解压**

unzipelasticsearch-5.1.1.zip

**4、运行**

./bin/elasticsearch

./bin/elasticsearch-d          \#后台运行

tail -flogs/elasticsearch.log          \#查看日志

**注：[ES][]有执行脚本的能力，因安全因素，不能在root用户下运行，强行运行会报如下错误：**

org.elasticsearch.bootstrap.StartupException:java.lang.RuntimeException: can not run elasticsearch as root

**解决方案：**

groupadd es          \#增加es组

user add es -g es -p pwd          \#增加es用户并附加到es组

chown -R es:es elasticsearch-5.1.1         \#给目录权限

sues          \#使用es用户

./bin/elasticsearch-d          \#后台运行es

**外网访问**

viconf/elasticsearch.yml

修改network.host: 0.0.0.0

**再次启动linux可能出现如下类似错误 **

bootstrapchecks failed

max filedescriptors \[65535\] for elasticsearch process is too low, increase to at least\[65536\]

**解决方案**

启动失败，检查没有通过，报错

\[2018-05-18T17:44:59,658\]\[INFO \]\[o.e.b.BootstrapChecks    \] \[gFOuNlS\] bound or publishing to a non-loopback address, enforcing bootstrap checks  
ERROR: \[2\] bootstrap checks failed  
\[1\]: max file descriptors \[4096\] for elasticsearch process is too low, increase to at least \[65536\]

\[2\]: max virtual memory areas vm.max\_map\_count \[65530\] is too low, increase to at least \[262144\]

\[1\]: max file descriptors \[65535\] for elasticsearch process is too low, increase to at least \[65536\]

编辑 /etc/security/limits.conf，追加以下内容；  
\* soft nofile 65536  
\* hard nofile 65536  
此文件修改后需要重新登录用户，才会生效

\[2\]: max virtual memory areas vm.max\_map\_count \[65530\] is too low, increase to at least \[262144\]

编辑 /etc/sysctl.conf，追加以下内容：  
vm.max\_map\_count=655360  
保存后，执行：

sysctl -p

重新启动，成功。

3、重新使用SSH登录，再次启动elasticsearch即可。

外网访问：serverip:9200/

**安装elasticsearch-head插件**

elasticsearch5以后的版本比较新，不支持直接安装head插件，以下是github上提供的安装方法，如下图示

以下为我自己整理的方法，参考来源：http://blog.csdn.net/qq942477618/article/details/53637817

1、下载head插件  
  
wgethttps://codeload.github.com/mobz/elasticsearch-head/zip/master  
  
2、下载nodejs  
  
nodejs官网下载地址https://nodejs.org/dist/  
  
wgethttps://nodejs.org/dist/v6.9.2/node-v6.9.2-linux-x64.tar.xz  
  
3、配置node环境变量  
  
xz –d node-v6.9.2-linux-x64.tar.xz  
tar –xvf node-v6.9.2-linux-x64.tar  
mv node-v6.9.2-linux-x64 /alidata/app/node  
  
vim /etc/profile  
export NODE\_HOME=/alidata/app/node  
export PATH=$PATH:$NODE\_HOME/bin  
source /etc/profile  
  
\# node –v  
v6.9.2  
\# npm –v  
3.10.9  
  
4、安装grunt  
  
cd elasticsearch-head-master  
npm install -g grunt--registry=https://registry.npm.taobao.org  
  
5、测试一下  
  
cd elasticsearch-head-master  
grunt  
  
出现以下提示，为Gruntfile.js引用的，缺少以下包  
  
>> Local Npm module"grunt-contrib-clean" not found. Is it installed?  
>> Local Npm module"grunt-contrib-concat" not found. Is it installed?  
>> Local Npm module"grunt-contrib-watch" not found. Is it installed?  
>> Local Npm module"grunt-contrib-connect" not found. Is it installed?  
>> Local Npm module"grunt-contrib-copy" not found. Is it installed?  
>> Local Npm module "grunt-contrib-jasmine"not found. Is it installed?  
Warning: Task "connect:server" notfound. Use --force to continue.  
  
Aborted due to warnings.  
  
安装  
  
npm install grunt-contrib-clean--registry=https://registry.npm.taobao.org  
  
npm install grunt-contrib-concat --registry=https://registry.npm.taobao.org  
  
npm install grunt-contrib-watch--registry=https://registry.npm.taobao.org  
npm install grunt-contrib-connect--registry=https://registry.npm.taobao.org  
npm install grunt-contrib-copy--registry=https://registry.npm.taobao.org  
npm install grunt-contrib-jasmine--registry=https://registry.npm.taobao.org  
  
6、运行  
  
grunt server  
  
  
7、测试  
  
http://serverip:9100/  
  
修改head目录下的Gruntfile.js配置，head默认监听127.0.0.1  
  
vm Gruntfile.js  
  
hostname: '0.0.0.0',  
  
8、为es设置跨域访问  
  
vi config/elasticsearch.yml        \#新增两行  
  
http.cors.enabled: true  
  
http.cors.allow-origin: "\*"

9、启动es，启动head插件
