之前裝過一次 ELK 7.7，相比之下裝 8.7可方便太多了~??
?

?
JAVA
ELK會自己使用內置版本的JDK
?
ElasticSearch

?
Kinbana
8.7.0 下載地址 Download Kibana Free | Get Started Now | Elastic
?
Logstash
8.7.0 下載地址 Download Logstash Free | Get Started Now | Elastic

安裝ElasticSearch8
? 加入資源
rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
在/etc/yum.repos.d/位置創建文件elasticsearch.repo
cd /etc/yum.repos.d/
vim elasticsearch.repo
輸入如下內容：
[elasticsearch] name=Elasticsearch repository for 8.x packages baseurl=https://artifacts.elastic.co/packages/8.x/yum gpgcheck=1 gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch enabled=0 autorefresh=1 type=rpm-md
?
將鏡像從?mirror.centos.org?更改為?vault.centos.org (yum可用，則跳過)
進入到 yum 的 repos 目錄
cd /etc/yum.repos.d/
修改 centos 文件內容
sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-* sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*
生成緩存更新
yum makecache
運行 yum update，并且重新安裝 vim
yum update -y
yum -y install vim
?
? 執行 yum 命令完成 es 安裝
yum install --enablerepo=elasticsearch elasticsearch
安裝完記得保存如下信息，便于后續使用
Authentication and authorization are enabled. TLS for the transport and HTTP layers is enabled and configured. The generated password for the elastic built-in superuser is : xxxxxxxxx If this node should join an existing cluster, you can reconfigure this with '/usr/share/elasticsearch/bin/elasticsearch-reconfigure-node --enrollment-token <token-here>' after creating an enrollment token on your existing cluster. You can complete the following actions at any time: Reset the password of the elastic built-in superuser with '/usr/share/elasticsearch/bin/elasticsearch-reset-password -u elastic'. Generate an enrollment token for Kibana instances with '/usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s kibana'. Generate an enrollment token for Elasticsearch nodes with '/usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s node'.
?
添加用戶和用戶組 es 并未用戶組提供文件夾權限
groupadd es useradd es -g es -p password chown es:es -R /usr/share/elasticsearch chown es:es -R /etc/elasticsearch chown es:es -R /var/lib/elasticsearch chown es:es -R /var/log/elasticsearch
chown es:es -R /var/
chmod 777 /etc/elasticsearch chmod 777 /usr/share/elasticsearch/ chmod 777 /etc/sysconfig/elasticsearch
?
?編輯 elasticsearch.yml 配置文件
cd /etc/elasticsearch
vim elasticsearch.yml
配置如下：
network.host: 0.0.0.0 http.port: 9200 xpack.security.enabled: false
使用 es 賬號啟動 ElasticSearch
cd /usr/share/elasticsearch/bin/
su es
bin/elasticsearch -d
?
關閉防火墻或者開放9200端口，即可通過 IP:9200 訪問
# 查看防火墻狀態
systemctl status firewalld.service
# 關閉防火墻
systemctl stop firewalld.service
?
? 如果遇到安全提示則選擇繼續訪問，并輸入用戶名密碼這個用到的用戶名密碼是安裝Es后我們保存的那個哦
?
安裝 Kibana
在 /etc/yum.repos.d/ 位置創建文件 kibana.repo
cd /etc/yum.repos.d/
vim kibana.repo
輸入如下內容
[kibana-8.x] name=Kibana repository for 8.x packages baseurl=https://artifacts.elastic.co/packages/8.x/yum gpgcheck=1 gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch enabled=1 autorefresh=1 type=rpm-md
執行yum命令完成安裝
yum install kibana
修改 kibana 配置文件
vim /etc/kibana/kibana.yml
增加如下內容：
server.host: "0.0.0.0"
server.post: 5601
以root后臺啟動服務
nohup /usr/share/kibana/bin/kibana --allow-root &
在ES安裝目錄 執行如下代碼獲取 token (本文 8.7 版本不需要)
/usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s kibana
? 關閉防火墻或者開啟5601端口，并使用瀏覽器訪問 IP:5601
?
安裝 Logstash
在 /etc/yum.repos.d/ 位置創建文件 logstash.repo
cd /etc/yum.repos.d/
vim logstash.repo
輸入如下內容：
[logstash-8.x] name=Elastic repository for 8.x packages baseurl=https://artifacts.elastic.co/packages/8.x/yum gpgcheck=1 gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch enabled=1 autorefresh=1 type=rpm-md
執行yum命令完成安裝
yum install logstash
安裝完成后的啟動目錄
/usr/share/logstash/bin/logstash
在 /etc/logstash/ 目錄下創建 logstash.conf 配置文件
cd /etc/logstash/
vim logstash.conf
輸入如下內容，以搜集 Nginx 的日志
#---------------------------------------------------------------- nginx----------------------------------------------------------------------- input { file { type => "nginx-error-log" path => "/usr/local/nginx/logs/error.log" } file { type => "nginx-access-log" path => "/usr/local/nginx/logs/access.log" codec => json } } filter { if [type] =~ "nginx-error-log" { grok { match => { "message" => "(?<datetime>\d{4}/\d{2}/\d{2} \d{2}:\d{2}:\d{2}) \[(?<errtype>\w+)\] \S+: \*\d+ (?<errmsg>[^,]+), (?<errinfo>.*$)" } } mutate { rename => { "message" => "z_message" "host" => "fromhost" } } } else if [type] =~ "nginx-access-log" { mutate { split => {"upstremtime" => ","} } mutate { convert => { "upstremtime" => "float"} } } if [errinfo] { ruby { code => " new_event = LogStash::Event.new(Hash[event.get('errinfo').split(', ').map{ |l| l.split(': ') }]) new_event.remove('@timestamp') event.append(new_event) " } grok { match => { "request" => '"%{WORD:verb} %{URIPATHPARAM:urlpathparam}?(?: HTTP/%{NUMBER:httpversion})"' } patterns_dir => ["/home/data/logstash/patterns/"] remove_field => [ "errinfo","request" ] } } } output { #elasticsearch { host => localhost } stdout { codec => rubydebug } if [type] =~ "nginx-error-log" { elasticsearch { hosts => ["http://ES的域名或者IP地址"] index => "logstash-nginx-error-log-%{+YYYY.MM.dd}" document_type => "data" user => "es用戶名" password => "es密碼" } }else if [type] =~ "nginx-access-log" { elasticsearch { hosts => ["http://ES的域名或者IP地址"] index => "logstash-nginx-access-log-%{+YYYY.MM.dd}" document_type => "data" user => "es用戶名" password => "es密碼" } } }
指定配置文件，啟動 logstash
/usr/share/logstash/bin/logstash -f /etc/logstash/logstash.conf
?
格式化 Nginx 日志
進入 nginx 配置文件（以各自的文件目錄、文件名為準）
cd /usr/local/nginx/conf/
vim nginx.conf
在 http 里輸入如下內容：
log_format main '{"@timestamp":"$time_iso8601",' '"host":"$server_addr",' ' "clientip" : "$remote_addr",' ' "size" : "$body_bytes_sent" ,' '"respnsetime":"$request_time",' '"upstremtime":"$upstream_response_time",' '"upstremhost":"$upstream_addr",' '"httphost":"$host",' '"referer":"$http_referer",' '"xff":"$http_x_forwarded_for",' '"agent":"$http_user_agent",' '"clientip":"$remote_addr",' '"request":"$request",' '"uri":"$uri",' '"status":"$status"}'; access_log /usr/local/nginx/logs/access.log main; error_log /usr/local/nginx/logs/error.log error;
重新加載 Nginx?
/usr/local/nginx/sbin/nginx -s reload
進入 kibana，就能看到推過來的 Nginx 的日志
