1.下载安装包
https://www.elastic.co/cn/downloads/elasticsearch我下的是Linux环境的tar包
2.解压安装包
tar -xvf elasticsearch-6.1.1.tar.gz
3.启动命令
切换普通用户,进入bin目录启动./elasticsearch或./elasticsearch -d(守护进程)
4.如果有报错按照下面方法解决
1、启动 elasticsearch 如出现异常 can not run elasticsearch as root 解决方法:创建ES 账户,修改文件夹 文件 所属用户 组 2、启动异常:ERROR: bootstrap checks failed system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk 问题原因:因为Centos6不支持SecComp,而ES5.2.1默认bootstrap.system_call_filter为true进行检测,所以导致检测失败,失败后直接导致ES不能启动。详见 :https://github.com/elastic/elasticsearch/issues/22899 解决方法:在elasticsearch.yml中配置bootstrap.system_call_filter为false,注意要在Memory下面: bootstrap.memory_lock: false bootstrap.system_call_filter: false 3、启动后,如果只有本地可以访问,尝试修改配置文件 elasticsearch.yml 中network.host(注意配置文件格式不是以 # 开头的要空一格, : 后要空一格) 为 network.host: 0.0.0.0 默认端口是 9200 注意:关闭防火墙 或者开放9200端口 4、ERROR: bootstrap checks failed max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536] max number of threads [1024] for user [lishang] likely too low, increase to at least [2048] 解决方法:切换到root用户,编辑limits.conf 添加类似如下内容 vi /etc/security/limits.conf 添加如下内容: * soft nofile 65536 * hard nofile 131072 * soft nproc 2048 * hard nproc 4096 5、max number of threads [1024] for user [lish] likely too low, increase to at least [2048] 解决:切换到root用户,进入limits.d目录下修改配置文件。 vi /etc/security/limits.d/90-nproc.conf 修改如下内容: * soft nproc 1024 #修改为 * soft nproc 2048 6、max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144] 解决: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 然后,重新启动elasticsearch,即可启动成功。
5.下载head插件
git clone https://github.com/mobz/elasticsearch-head.git
6.安装node
wget https://npm.taobao.org/mirrors/node/latest-v4.x/node-v4.4.7-linux-x64.tar.gz
tar -zxvf node-v4.4.7-linux-x64.tar.gz
配置下环境变量,编辑/etc/profile添加
执行 source /etc/profile
7.安装grunt
cd elasticsearch-head目录下执行
npm install -g grunt-cli
8.npm安装依赖
到elasticsearch-head-master目录下,运行命令:
npm install -g cnpm --registry=https://registry.npm.taobao.org
9.修改Elasticsearch配置文件
编辑elasticsearch-5.1.1/config/elasticsearch.yml,加入以下内容
http.cors.enabled: true
http.cors.allow-origin: "*"
10.打开elasticsearch-head-master/Gruntfile.js,找到下面connect属性,新增hostname: ‘0.0.0.0’:
connect: { server: { options: { hostname: ‘0.0.0.0‘, port: 9100, base: ‘.‘, keepalive: true } } }
11.启动elasticsearch-head
grunt server
后台启动:
nohup grunt server &exit
