新增用户/组

(ES启动是不允许使用root用户)

groupadd elsearch

useradd elsearch -g elsearch -p elasticsearch

启动

切换到elsearch用户

su elsearch

cd /usr/local/elasticsearch-5.5.2/

./bin/elasticsearch

安装ik中文分词器

下载（注意，下载对应的版本，本文下载的是5.5.2）

https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v5.5.2/elasticsearch-analysis-ik-5.5.2.zip

解压

首先在ES安装目录下的plugins目录下新建目录ik

cd /usr/local/elasticsearch-5.5.2/plugins

mkdir ik

再将分词器解压到ik目录下（先解压再移动/复制也可以）

unzip 命令（如果出现command not found，安装一下yum -y install unzip）

解压后的目录结构：

[root@es1 ik]# cd /opt/install/elasticsearch-5.5.2/plugins/ik/

[root@es1 ik]# ll

server.port: 5601 # 配置kibana的端口

server.host: 192.168.100.101 # 配置监听ip

elasticsearch.url: "http://192.168.100.101:9200" # 配置es服务器的ip，如果是集群则配置该集群中主节点的ip

logging.dest: /var/log/kibana.log # 配置kibana的日志文件路径，不然默认是messages里记录日志

补充

elasticsearch-head安装

下载：

Git地址： git clone

进入 elasticsearch-head目录：cd命令

执行命令：npm install

如果出现下面的错误：

@font-face{ font-family:"Times New Roman"; } @font-face{ font-family:"宋体"; } @font-face{ font-family:"Calibri"; } p.MsoNormal{ mso-style-name:正文; mso-style-parent:""; margin:0pt; margin-bottom:.0001pt; mso-pagination:none; text-align:justify; text-justify:inter-ideograph; font-family:Calibri; mso-fareast-font-family:宋体; mso-bidi-font-family:'Times New Roman'; font-size:10.5000pt; mso-font-kerning:1.0000pt; } span.msoIns{ mso-style-type:export-only; mso-style-name:""; text-decoration:underline; text-underline:single; color:blue; } span.msoDel{ mso-style-type:export-only; mso-style-name:""; text-decoration:line-through; color:red; } @page{mso-page-border-surround-header:no; mso-page-border-surround-footer:no;}@page Section0{ } div.Section0{page:Section0;}

执行下面的：

npm install phantomjs-prebuilt@2.1.16 --ignore-scripts

修改/etc/sysctl.conf 文件否则会报max virtual memory areas vm.max_map_count [65530]切换到root用户修改配置sysctl.conf

vi /etc/sysctl.conf

添加下面配置：

vm.max_map_count=655360

并执行命令：

sysctl -p

修改/etc/security/limits.conf文件，否则会报max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536]错误

vim /etc/security/limits.conf

* soft nofile 65536

* hard nofile 65536
