安装ElasticSearch8
加入资源
rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
在/etc/yum.repos.d/位置创建文件elasticsearch.repo
cd /etc/yum.repos.d/vim elasticsearch.repo
输入如下内容:
[elasticsearch] name=Elasticsearch repository for 8.x packages baseurl=https://artifacts.elastic.co/packages/8.x/yumgpgcheck=1gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearchenabled=0autorefresh=1type=rpm-md
将镜像从 mirror.centos.org 更改为 vault.centos.org (yum可用,则跳过)
进入到 yum 的 repos 目录
cd /etc/yum.repos.d/
修改 centos 文件内容
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-*
生成缓存更新
yum makecache
运行 yum update,并且重新安装 vim
yum update -y yum -y install vim
执行 yum 命令完成 es 安装
yum install --enablerepo=elasticsearch elasticsearch
安装完记得保存如下信息,便于后续使用
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'.
添加用户和用户组 es 并未用户组提供文件夹权限
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
编辑 elasticsearch.yml 配置文件
cd /etc/elasticsearch vim elasticsearch.yml
配置如下:
network.host: 0.0.0.0http.port: 9200xpack.security.enabled: false
使用 es 账号启动 ElasticSearch
cd /usr/share/elasticsearch/bin/su es bin/elasticsearch -d
关闭防火墙或者开放9200端口,即可通过 IP:9200 访问
# 查看防火墙状态
systemctl status firewalld.service
# 关闭防火墙
systemctl stop firewalld.service
如果遇到安全提示则选择继续访问,并输入用户名密码这个用到的用户名密码是安装Es后我们保存的那个哦
安装 Kibana
在 /etc/yum.repos.d/ 位置创建文件 kibana.repo
cd /etc/yum.repos.d/vim kibana.repo
输入如下内容
[kibana-8.x] name=Kibana repository for 8.x packages baseurl=https://artifacts.elastic.co/packages/8.x/yumgpgcheck=1gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearchenabled=1autorefresh=1type=rpm-md
执行yum命令完成安装
yum install kibana
修改 kibana 配置文件
vim /etc/kibana/kibana.yml
增加如下内容:
server.host:
以root后台启动服务
nohup /usr/share/kibana/bin/kibana --allow-root &
在ES安装目录 执行如下代码获取 token (本文 8.7 版本不需要)
/usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s kibana
关闭防火墙或者开启5601端口,并使用浏览器访问 IP:5601
安装 Logstash
在 /etc/yum.repos.d/ 位置创建文件 logstash.repo
cd /etc/yum.repos.d/vim logstash.repo
输入如下内容:
[logstash-8.x] name=Elastic repository for 8.x packages baseurl=https://artifacts.elastic.co/packages/8.x/yumgpgcheck=1gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearchenabled=1autorefresh=1type=rpm-md
执行yum命令完成安装
yum install logstash
安装完成后的启动目录
/usr/share/logstash/bin/logstash
在 /etc/logstash/ 目录下创建 logstash.conf 配置文件
cd /etc/logstash/vim logstash.conf
输入如下内容,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 {

}
}
mutate {

}
} else if [type] =~ "nginx-access-log" {
mutate {

}
mutate {

}
}
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 {

}
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用户名"
password => "es密码"
}
}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用户名"
password => "es密码"
}
}
}指定配置文件,启动 logstash
/usr/share/logstash/bin/logstash -f /etc/logstash/logstash.conf
格式化 Nginx 日志
进入 nginx 配置文件(以各自的文件目录、文件名为准)
cd /usr/local/nginx/conf/vim nginx.conf
在 http 里输入如下内容:
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;重新加载 Nginx
/usr/local/nginx/sbin/nginx -s reload
进入 kibana,就能看到推过来的 Nginx 的日志
