部署 elk 日志系统 elasticsearch、logstash、 kibana
安装elk
安装Java 1.8环境
解压源码安装包：
tar xf jdk-8u121-linux-x64.tar.gz
ll
mkdir /work/opt -p
mv jdk1.8.0_121 /work/opt/jdk
ll /work/opt/jdk/
chown -R root.root /work/opt
vim /etc/profile : //添加
export JAVA_HOME=/work/opt/jdk
export JAVA_BIN=$JAVA_HOME/bin
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=$JAVA_HOME/jre/lib/ext:$JAVA_HOME/lib/tools.jar
export PATH=$JAVA_BIN:$PATH
安装 elasticsearch-5.3.0
tar xf elasticsearch-5.3.0.tar.gz mv elasticsearch-5.3.0 /work/opt/elasticsearch ubuntu@ip-172-31-1-79:/work/opt/elasticsearch/config$ egrep -v ‘#|^$‘ elasticsearch.yml cluster.name: lvnian-elk node.name: lvnian-elk-node1 path.data: /data #由于是普通用户启动elasticsearch，所以这个目录的属主需要改为普通用户 path.logs: /work/opt/elasticsearch/logs #由于是普通用户启动elasticsearch，所以这个目录的属主需要改为普通用户 bootstrap.memory_lock: false network.host: 0.0.0.0 http.port: 9200 http.cors.enabled: true http.cors.allow-origin: "*" ubuntu@ip-172-31-1-79:/work/opt/elasticsearch/config$ nohup /work/opt/elasticsearch/bin/elasticsearch >> /tmp/elasticsearch.log &
##ES 5.1.1 安装 head：
（5.1.1版本的 elasticsearch 没有提供直接插件安装方法，但在该github上该插件作者给出了方法）
下载二进制源码包： wget https://nodejs.org/dist/v4.2.2/node-v6.2.0-linux-x64.tar.gz 解压： tar xf node-v6.2.0-linux-x64.tar.gz -C /work/opt/ 设置环境变量： vim /etc/profile： export NODE_HOME=/work/opt/node/ export PATH=$PATH:$NODE_HOME/bin root@ip-172-31-1-79:/work/source# node --version v6.10.1 npm config set registry https://registry.npm.taobao.org //设置代理镜像源，加速下载 cd /home/stt/node-v4.2.2-linux-x64/lib/node_modules npm install grunt //显示的2条warn可以忽略
测试grunt是否生效：
$ grunt -version grunt-cli v1.2.0 grunt v1.0.1
安装head插件：
下载：git clone git://github.com/mobz/elasticsearch-head.git
cd /home/stt/elasticsearch-head
npm install (提示：如果遇到网络的瓶颈，将预先下载的源码包放在对应的位置效果一样，目录为/tmp/phantomjs/，确定位置后可自行创建并上传包)
修改 elasticsearch-head/ _site/app.js
// 把localhost改为ip
找到：
this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://localhost:9200";
改为：
this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://192.168.8.116:9200";
修改 elasticsearch-head/Gruntfile.js
connect: {
server: {
options: {
hostname: "0.0.0.0", //增加这个配置
port: 9100,
base: ‘.‘,
keepalive: true
}
}
} 启动服务：（后台运行）
grunt server & //需要在 /home/stt/elasticsearch-head 下执行，因为我的 grunt 没有进行全局的安装
##安装Logstash(这个软件在你需要读取的日志服务上安装，用logstash读取你的日志，上传给elasticsearch的):
也需要安装java1.8环境
tar xf logstash-5.3.0.tar.gz mkdir /work/opt mv logstash-5.3.0 /work/opt/ cd /work/opt/
vim /work/opt/logstash-5.3.0/conf/central.conf #(处理基于 FILE 方式输入的日志信息，这里是简单的举个例子，日后继续学习补充)
input {
file {
path => "/tmp/*.log"
}
}
output {
elasticsearch {
hosts => "192.168.8.116:9200"
index => "nginx-access"
}
stdout {
codec => rubydebug
}
}
##安装Kibana：
解压源码包：
tar zxf kibana-5.1.1-linux-x86_64.tar.gz -C /home/stt/server/ vim config/kibana.yml //修改 server.port: 5601 //打开注释而已，不用可以去效果，请使用默认端口 server.host: "0.0.0.0" //打开监听地址，让别的机器也能访问这个 kibana elasticsearch.url: "http://127.0.0.1:9200" //这个url要根据实质情况，添加访问 elasticsearch 的url 启动服务： （后台运行） /home/stt/server/kibana-5.1.1-linux-x86_64/bin/kibana &
安装nginx 反向代理，
apt-gei install nginx
nginx放心代理配置文件如下：
##文件名kibana.conf
upstream backend {
server 172.31.6.155:5601;
}
server {
listen 80;
server_name kibana.lvnian.co;
access_log /tmp/kibana-access.log;
error_log /tmp/kibana-error.log;
location / {
#设置主机头和客户端真实地址，以便服务器获取客户端真实IP
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
#禁用缓存
proxy_buffering off;
#反向代理的地址
proxy_pass http://backend;
}
}
logstash 读取nginx的访问日志以及error日志，上传到logstash的配置文件文件。
用下面命令运行即可
nohup /work/opt/logstash-5.3.0/bin/logstash -f /work/opt/logstash-5.3.0/conf/elk-nginx-log.conf &
文件名： elk-nginx-log.conf
