一、环境信息以及安装前准备
主机信息（内存尽可能大点）
软件版本
部署前操作
关闭防火墙selinux等，开机自启关掉 同步时间服务器 [root@hk-elk-elastic5 java]# systemctl stop firewalld [root@hk-elk-elastic5 java]# systemctl disable firewalld.service [root@hk-elk-elastic5 java]# crontab -l 0 */8 * * * /usr/sbin/ntpdate 10.20.1.1;/sbin/hwclock -w
二、redis启动
具体查看官网redis的启动和配置
三、elasticsearch集群安装配置
1、elk安装需要java环境以及创建elk用户
[root@hk-elk-elastic1 java]# rpm -ivh jdk-8u181-linux-x64.rpm [root@hk-elk-elastic1 java]# vim /etc/profile #配置java环境变量 JAVA_HOME=/usr/java/jdk1.8.0_181-amd64 CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar PATH=$JAVA_HOME/bin:$PATH export PATH JAVA_HOME CLASSPATH [root@hk-elk-elastic1 ~]# groupadd elastic [root@hk-elk-elastic1 ~]# useradd -g elastic elastic [root@hk-elk-elastic1 ~]# chown elastic:elastic /usr/local/elk -R #给目录相关权限 [root@hk-elk-elastic1 ~]# chown elastic:elastic /data -R [root@hk-elk-elastic1 ~]# mkdir /data/log -p #创建data数据目录，以及log日志目录 [root@hk-elk-elastic1 java]# sudo -u elastic java -version #用elastic查看是有有java权限 java version "1.8.0_181" Java(TM) SE Runtime Environment (build 1.8.0_181-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)
2、安装以及配置elasticsearch（master）
[root@hk-elk-elastic1 java]# cd /usr/local/elk/ [root@hk-elk-elastic1 elk]# tar -xf elasticsearch-6.3.0.tar.gz ##配置elasticsearch内存，最大不能超过32G，最好配置系统内存的一半 [root@hk-elk-elastic1 elk]# vim elasticsearch-6.3.0/config/jvm.options -Xms8g -Xmx8g [root@hk-elk-elastic1 elk]# grep "^[a-z]" elasticsearch-6.3.0/config/elasticsearch.yml cluster.name: hk-elk-application #集群名称 node.name: hk-elk-master1 #节点名 ##master2、master3只有此处的节点名不同，其余配置均一样 node.master: true #担任master选举 node.data: false #不作为data存储数据 path.data: /data #data目录 path.logs: /data/log #日志目录 network.host: 10.20.11.205 #监听ip http.port: 9200 #监听端口 transport.tcp.port: 9300 #通信端口 discovery.zen.ping.unicast.hosts: ["10.20.11.205:9300","10.20.11.206:9300","10.20.11.207:9300"] #master主机通信端口 discovery.zen.minimum_master_nodes: 2 #这个值为（master/2）+1，防止集群脑裂 discovery.zen.ping_timeout: 60s #master之间的通信时间，考虑到网络因数，设置为60s
安装以及配置elasticsearch（data）
[root@hk-elk-elastic4 elk]# grep "^[a-z]" elasticsearch-6.3.0/config/elasticsearch.yml cluster.name: hk-elk-application node.name: hk-elk-data2 #节点名 ##data2只有此处节点名不同，其余配置均一样 node.master: false #不担任master选举 node.data: true #担任数据节点 path.data: /data path.logs: /data/log network.host: 10.20.11.209 http.port: 9200 transport.tcp.port: 9300 discovery.zen.ping.unicast.hosts: ["10.20.11.205:9300","10.20.11.206:9300","10.20.11.207:9300"]
设置打开文件描述符、进程数、内存限制，以及内核参数
[root@hk-elk-elastic1 elk]# vim /etc/security/limits.conf * soft nofile 65536 * hard nofile 65536 * soft memlock unlimited * hard memlock unlimited [root@hk-elk-elastic1 elk]# vim /etc/security/limits.d/20-nproc.conf * soft nproc 20480 root soft nproc unlimited [root@hk-elk-elastic1 elk]# vim /etc/sysctl.conf vm.max_map_count=655360 net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 [root@hk-elk-elastic1 elk]# systemctl -p #使用此命令，可使配置立即生效
启动elasticsearch服务
[root@hk-elk-elastic1 elk]# cat /root/elastic.sh sudo -u elastic /usr/local/elk/elasticsearch-6.3.0/bin/elasticsearch -d &&tailf /data/log/hk-elk-application.log
通过屏幕输出看到服务启动并通过自动发现的模式，将其他节点添加进来，我们可以查看集群状态
[root@hk-elk-elastic1 elk]# curl -u http://10.20.11.205:9200/_cat/health?v 集群名称 状态 总数 data数 epoch timestamp cluster status node.total node.data shards pri relo init unassign pending_tasks max_task_wait_time active_shards_percent 1540902792 20:33:12 hk-elk-application green 5 2 30 15 0 0 0 0 - 100.0% [root@hk-elk-elastic1 elk]# curl -u http://10.20.11.205:9200/_cat/nodes?v ip heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name 10.20.11.205 4 65 0 0.00 0.01 0.05 mi * hk-elk-master1 ##该节点被选举为master 10.20.11.207 3 63 0 0.00 0.01 0.05 mi - hk-elk-master3 10.20.11.209 7 63 0 0.00 0.01 0.05 di - hk-elk-data2 10.20.11.208 8 63 0 0.00 0.03 0.05 di - hk-elk-data1 10.20.11.206 4 63 0 0.00 0.01 0.05 mi - hk-elk-master2
四、安装配置kibana
[root@hk-elk-kibana elk]# tar -xf kibana-6.3.0-linux-x86_64.tar.gz ^C [root@hk-elk-kibana elk]# grep "^[a-z]" kibana-6.3.0-linux-x86_64/config/kibana.yml server.port: 5601 #端口 server.host: "10.20.11.215" #监听ip elasticsearch.url: "http://10.20.11.205:9200" #elasticsearch机器ip以及端口 [root@hk-elk-kibana elk]# cat /root/kibana.sh #启动脚本 #!/bin/bash /usr/local/elk/kibana-6.3.0-linux-x86_64/bin/kibana > /dev/null 2>&1 &
可以看的到elasticsearch集群的相关主机信息等
五、破解x-pack插件（#只供学习使用）
由于在elasticsearch在6.3版本之后x-pack是默认安装好的，所以不再需要用户自己去安装
1、生成新的x-pack-core-6.3.0.jar包，替换原有的项目包
[root@hk-elk-elastic1 elk]# vim LicenseVerifier.java
package org.elasticsearch.license;
import java.nio.*; import java.util.*;
import java.security.*;
import org.elasticsearch.common.xcontent.*;
import org.apache.lucene.util.*;
import org.elasticsearch.common.io.*;
import java.io.*;
public class LicenseVerifier {
public static boolean verifyLicense(final License license, final byte[] encryptedPublicKeyData) {
return true;
}
public static boolean verifyLicense(final License license) {
return true;
}
}
[root@hk-elk-elastic1 elk]# vim XPackBuild.java
package org.elasticsearch.xpack.core;
import org.elasticsearch.common.io.*;
import java.net.*;
import org.elasticsearch.common.*;
import java.nio.file.*;
import java.io.*;
import java.util.jar.*;
public class XPackBuild {
public static final XPackBuild CURRENT;
private String shortHash;
private String date;
@SuppressForbidden(reason = "looks up path of xpack.jar directly") static Path getElasticsearchCodebase() {
final URL url = XPackBuild.class.getProtectionDomain().getCodeSource().getLocation();
try { return PathUtils.get(url.toURI()); }
catch (URISyntaxException bogus) {
throw new RuntimeException(bogus); }
}
XPackBuild(final String shortHash, final String date) {
this.shortHash = shortHash;
this.date = date;
}
public String shortHash() {
return this.shortHash;
}
public String date(){
return this.date;
}
static {
final Path path = getElasticsearchCodebase();
String shortHash = null;
String date = null;
Label_0157: { shortHash = "Unknown"; date = "Unknown";
}
CURRENT = new XPackBuild(shortHash, date);
}
}
[root@hk-elk-elastic1 elk]# javac -cp "/usr/local/elk/elasticsearch-6.3.0/lib/elasticsearch-6.3.0.jar:/usr/local/elk/elasticsearch-6.3.0/lib/lucene-core-7.3.1.jar:/usr/local/elk/elasticsearch-6.3.0/modules/x-pack/x-pack-core/x-pack-core-6.3.0.jar" LicenseVerifier.java
[root@hk-elk-elastic1 elk]# javac -cp "/usr/local/elk/elasticsearch-6.3.0/lib/elasticsearch-6.3.0.jar:/usr/local/elk/elasticsearch-6.3.0/lib/lucene-core-7.3.1.jar:/usr/local/elk/elasticsearch-6.3.0/modules/x-pack/x-pack-core/x-pack-core-6.3.0.jar:/usr/local/elk/elasticsearch-6.3.0/lib/elasticsearch-core-6.3.0.jar" XPackBuild.java
[root@hk-elk-elastic1 elk]# cp -a /usr/local/elk/elasticsearch-6.3.0/modules/x-pack/x-pack-core/x-pack-core-6.3.0.jar .
[root@hk-elk-elastic1 elk]# jar -xf x-pack-core-6.3.0.jar
[root@hk-elk-elastic1 elk]# rm -rf LicenseVerifier.java XPackBuild.java x-pack-core-6.3.0.jar
[root@hk-elk-elastic1 elk]# cp -a LicenseVerifier.class org/elasticsearch/license/
[root@hk-elk-elastic1 elk]# cp -a XPackBuild.class org/elasticsearch/xpack/core/
[root@hk-elk-elastic1 elk]# rm -rf LicenseVerifier.class XPackBuild.class
[root@hk-elk-elastic1 elk]# jar -cvf x-pack-core-6.3.0.jar *
[root@hk-elk-elastic1 elk]# cp -a x-pack-core-6.3.0.jar /usr/local/elk/elasticsearch-6.3.0/modules/x-pack/x-pack-core/
[root@hk-elk-elastic1 elk]# vim /usr/local/elk/elasticsearch-6.3.0/config/elasticsearch.yml
xpack.security.enabled: false #关闭x-pack安全验证（3台master都需要操作）
2、重启elasticsearch服务，并上传license.json
[root@hk-elk-elastic1 config]# cat /root/license.json
{"license":{"uid":"2e44e23c-7087-447b-9a0e-398b8b7a917c","type":"platinum","issue_date_in_millis":1532649600000,"expiry_date_in_millis":2544271999999,"max_nodes":100,"issued_to":"han jiang (www.zfcloud.com)","issuer":"Web Form","signature":"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","start_date_in_millis":1532649600000}}
[root@hk-elk-elastic1 elk]# curl -XPUT -u elastic:chageme 'http://10.20.11.205:9200/_xpack/license' -H "Content-Type: application/json" -d @license.json #（3台master全部需要执行）
{"acknowledged":true,"license_status":"valid"}
看到这说明破解成功，但是6.0以上的版本需要强制开始ssl传输，所以我们需要配置SSL。
五、配置SSL并启动x-pack
1、创建证书
2、解压以及配置证书，拷贝到其他主机（master and data）
[root@hk-elk-elastic1 elk]# mkdir /tmp/cert [root@hk-elk-elastic1 elk]# mv cert.zip /tmp/cert/ [root@hk-elk-elastic1 elk]# cd /tmp/cert/
[root@hk-elk-elastic1 elk]# unzip cert.zip Archive: cert.zip creating: ca/ inflating: ca/ca.crt inflating: ca/ca.key creating: elasticsearch/ inflating: elasticsearch/elasticsearch.crt inflating: elasticsearch/elasticsearch.key [root@hk-elk-elastic1 elk]# ll 总用量 8 drwxrwxr-x 2 elastic elastic 34 9月 20 13:47 ca -rw------- 1 elastic elastic 5157 9月 20 13:47 cert.zip drwxrwxr-x 2 elastic elastic 56 9月 20 13:47 elasticsearch [root@hk-elk-elastic1 elk]# mv ca/* /usr/local/elasticsearch/config/ [root@hk-elk-elastic1 elk]# mv elasticsearch/* /usr/local/elasticsearch/config/ [root@hk-elk-elastic1 elk]# cd /usr/local/elasticsearch/config/ [root@hk-elk-elastic1 elk]# ll -rct #最后四个 总用量 48 -rw-rw---- 1 elastic elastic 0 9月 19 16:15 users_roles -rw-rw---- 1 elastic elastic 0 9月 19 16:15 users -rw-rw---- 1 elastic elastic 197 9月 19 16:15 roles.yml -rw-rw---- 1 elastic elastic 473 9月 19 16:15 role_mapping.yml -rw-rw---- 1 elastic elastic 6380 9月 19 16:15 log4j2.properties -rw-rw---- 1 elastic elastic 2942 9月 19 16:15 jvm.options -rw-r----- 1 elastic elastic 2853 9月 19 16:15 elasticsearch.yml-bak -rw-rw---- 1 elastic elastic 207 9月 19 16:20 elasticsearch.keystore -rw-rw---- 1 elastic elastic 2905 9月 20 13:27 elasticsearch.yml -rw-rw-r-- 1 elastic elastic 1671 9月 20 13:57 ca.key -rw-rw-r-- 1 elastic elastic 1200 9月 20 13:57 ca.crt -rw-rw-r-- 1 elastic elastic 1675 9月 20 13:57 elasticsearch.key -rw-rw-r-- 1 elastic elastic 1237 9月 20 13:57 elasticsearch.crt [root@hk-elk-elastic1 elk]# scp -pr *.crt root@10.20.11.[206--209]:/usr/local/elk/elasticsearch-6.3.0/config/ [root@hk-elk-elastic1 elk]# scp -pr *.crt root@10.20.11.[206--209]:/usr/local/elk/elasticsearch-6.3.0/config/
3、配置SSL，其他节点相同
[root@hk-elk-elastic1 elk]# grep "^[a-z]" /usr/local/elk/elasticsearch-6.3.0/config/elasticsearch.yml cluster.name: hk-elk-application node.name: hk-elk-master1 node.master: true node.data: false path.data: /data path.logs: /data/log network.host: 10.20.11.205 http.port: 9200 transport.tcp.port: 9300 discovery.zen.ping.unicast.hosts: ["10.20.11.205:9300","10.20.11.206:9300","10.20.11.207:9300"] discovery.zen.minimum_master_nodes: 2 discovery.zen.ping_timeout: 60s xpack.security.enabled: true #之前为false，现在需要打开 xpack.security.transport.ssl.enabled: true xpack.ssl.key: elasticsearch.key #路径需要自己写清楚 xpack.ssl.certificate: elasticsearch.crt xpack.ssl.certificate_authorities: ca.crt
4、重启elasticsearch服务
我们需要配置kabana的用户密码
5、创建elk集群相关的用户密码
[root@hk-elk-elastic1 elk]# ./elasticsearch-setup-passwords -h #查看命令帮助 Sets the passwords for reserved users Commands -------- auto - Uses randomly generated passwords #主要命令选项，表示系统将使用随机字符串设置密码 interactive - Uses passwords entered by a user #主要命令选项，表示使用用户输入的字符串作为密码 Non-option arguments: command Option Description ------ ----------- -h, --help show help -s, --silent show minimal output -v, --verbose show verbose output root@hk-elk-elastic1 elk]# ./elasticsearch-setup-passwords auto #为了演示效果，这里我们使用系统自动创建 Initiating the setup of passwords for reserved users elastic,kibana,logstash_system,beats_system. The passwords will be randomly generated and printed to the console. Please confirm that you would like to continue [y/N]y #选择y Changed password for user kibana #kibana角色和密码 PASSWORD kibana = SY8ubxQWUdFieDJNlJt6 Changed password for user logstash_system #logstash角色和密码 PASSWORD logstash_system = h9MkqxtCfJYRBx3NTruQ Changed password for user beats_system #beast角色和密码 PASSWORD beats_system = KEPbjSJuSuXGWMsSAvxx Changed password for user elastic #elasticsearch角色和密码 PASSWORD elastic = kijObt6nZkY9KU4CwJkn
#用户密码先保存下来。
kibana配置elasticsearch用户认证
[root@hk-elk-kibana elk]# grep "^elastic" /usr/local/elk/kibana-6.3.0-linux-x86_64/config/kibana.yml elasticsearch.url: "http://10.20.11.205:9200" elasticsearch.username: "elastic" elasticsearch.password: "kijObt6nZkY9KU4CwJkn"
重启kibana，打开界面
##在这里我们选择用elastic用户登入，刚踩的坑，如果用kibana用户登入，里面索引的数据会看不到
六、配置nginx日志，并配置logstash
1、配置nginx日志格式。
[root@cc conf]# vim /usr/local/tengine/conf/nginx.conf #配置elk的日志格式
log_format ELK '$remote_addr > ($hostname)$server_addr:$server_port - $remote_user [$time_local] $http_host "$request" '
'$status $body_bytes_sent "$http_referer" $upstream_status $upstream_addr $request_time $upstream_response_time '
'"$http_user_agent" "$http_x_forwarded_for"';
[root@cc conf]# vim /usr/local/tengine/conf/conf.d/test.conf #配置使用ELK格式生成nginx日志
access_log /home/nginx/nginx.log ELK;
2、搭建使用filebeat插件，将nginx日志发送到redis。
[root@cc~]# cd /usr/local/elk
[root@cc local]# tar -xf filebeat-6.3.1-linux-x86_64.tar.gz
[root@cc local]# cat filebeat-6.3.1-linux-x86_64/filebeat.yml | grep -v "#"
[root@cc local]# cat filebeat-6.3.1-linux-x86_64/filebeat.yml | grep -v "#"
filebeat.inputs:
- type: log
enabled: true
paths:
- '/home/nginx/*.log'
tags: ["nginxlog"]
document_type: nginxlog
tail_files: true
output.redis:
hosts: ["10.20.11.200:6379","10.20.11.200:6379","10.20.11.202:6379"]
db: 2 #redis数据库的一个整数索引标识，redis不同于mysql有一个库的名字。redis总共0-15默认16个库。
timeout: 5 #连接超时时间
key: "default_list" #以default_list的keys传输到redis
3、搭建配置logstash。
[root@hk-elk-logstash1 elk]# cd /usr/local/elk/
[root@hk-elk-logstash1 elk]# tar -xf logstash-6.3.0.tar.gz
[root@hk-elk-logstash1 elk]# vim /usr/local/elk/logstash-6.3.0/customconf/patterns/custompatterns #自定义一些正则，因为有些字段可能会匹配不到
URIPARM1 [A-Za-z0-9$.+!*'|(){},~@#%&/=:;^\_<>`?-[]]*

http://www.jianshu.com/p/07b82092d4af
具体配置：
# vim /usr/local/ELK/kibana-5.4.1-linux-x86_64/config/kibana.yml
添加最后添加，
tilemap.url: 'http://webrd02.is.autonavi.com/appmaptile?lang=zh_cn&size=1&scale=1&style=7&x={x}&y={y}&z={z}'
注意：加载地图需要时间，不会立刻显示汉化后的地图。

关于分片的两个问题
1） “我应该有多少个分片？”
答： 每个节点的分片数量保持在低于每1GB堆内存对应集群的分片在20-25之间。
2） “我的分片应该有多大”？
答：分片大小为50GB通常被界定为适用于各种用例的限制。
