安装 Elasticsearch
elasticsearch运行需要使用普通用户
修改 /etc/security/limits.conf
* soft nofile 600000 * hard nofile 600000 * soft nproc 60000 * hard nproc 60000 jt_app soft memlock unlimited jt_app hard memlock unlimited
修改/etc/sysctl.conf
net.ipv4.ip_forward = 1 net.ipv4.conf.default.rp_filter = 1 net.ipv4.conf.default.accept_source_route = 0 kernel.sysrq = 0 vm.swappiness = 0 kernel.core_uses_pid = 1 net.ipv4.tcp_syncookies = 1 kernel.msgmnb = 65536 kernel.msgmax = 65536 kernel.shmmax = 68719476736 kernel.shmall = 4294967296 net.core.somaxconn = 16384 vm.max_map_count = 262144
修改配置文件：

安装 Kibana
选择一台节点安装即可
进入安装目录修改配置文件：
config/kibana.yml
server.port: 5601 #端口
server.host: "elk-log-srv01" #访问ip地址
elasticsearch.url: "http://elk-log-srv01:9200" #连接elastic
kibana.index: ".kibana" #在elastic中添加.kibana索引
pid.file: /opt/kibana/kibana.pid
logging.dest: /opt/kibana/kibana.log
启动：
nohup ./bin/kibana &
logstash安装
elasticsearch 常用插件安装
只是版本不一样，方法是一样的，替换成自己的版本即可
采用离线安装插件的方法
1、sql插件
### 项目地址 https://github.com/NLPchina/elasticsearch-sql 历史版本： https://github.com/NLPchina/elasticsearch-sql/releases ### 下载sql插件 下载 wget https://github.com/NLPchina/elasticsearch-sql/releases/download/5.5.1.0/elasticsearch-sql-5.5.1.0.zip 安装 ./bin/elasticsearch-plugin install file:///opt/elasticsearch-sql-5.5.1.0.zip 安装web访问 wget https://github.com/NLPchina/elasticsearch-sql/releases/download/5.4.1.0/es-sql-site-standalone.zip unzip ./es-sql-site-standalone.zip cd site-server npm install express --save node node-server.js & #后台启动 默认端口：8080 cd _site vim controllers.js 修改链接es地址 url = "http://localhost:9200"

elasticsearch5.x安装head插件
5.0以上版本中不支持直接安装head插件，需要启动一个服务。 由于head插件本质上还是一个nodejs的工程，因此需要安装node，使用npm来安装依赖的包。（npm可以理解为maven） #安装git yum -y install git #下载源码 git clone git://github.com/mobz/elasticsearch-head.git 安装 nodejs，修改环境变量 node -v 2、安装npm 3、使用npm安装grunt 由于 npm 是国外的源，下载速度比较慢，推荐使用国内淘宝镜像 npm install -g cnpm --registry=https://registry.npm.taobao.org 下面开始修改 head 插件的配置 地址： https://github.com/mobz/elasticsearch-head
cerebro插件安装
以单独进程启动 下载 wget https://github.com/lmenezes/cerebro/releases/download/v0.6.6/cerebro-0.6.6.zip 解压 unzip cerebro-0.6.6.zip 启动： bin/cerebro -Dhttp.port=1234 -Dhttp.address=0.0.0.0 & ------------------------------------------------ 其他配置 -Dconfig.file=/some/other/dir/alternate.conf ##项目地址 https://github.com/lmenezes/cerebro
kibana安装x-pack插件
先下载x-pack-5.5.1.zip https://artifacts.elastic.co/downloads/packs 在线安装 bin/kibana-plugin install x-pack 离线安装 ./bin/kibana-plugin install file:///opt/x-pack-5.5.1.zip elasticsearch安装此插件一样
