目录
实验目标:构建filebeat+redis+logstash+es+kibana架构,实现elk访问
实验目标:构建filebeat+redis+logstash+es+kibana架构,实现elk访问
实验拓扑:es 192.168.8.5
Nginx 192.168.8.6
Logstash 192.168.8.7
es主机:192.168.8.5
1.安装elasticsearch:
前提:jdk-1.8.0
复制elasticsearch-6.6.0.rpm到虚拟机
rpm -ivh elasticsearch-6.6.0.rpm
2.修改配置文件:
vim /etc/elasticsearch/elasticsearch.yml
node.name: node-1
path.data: /data/elasticsearch
path.logs: /var/log/elasticsearch
bootstrap.memory_lock: true
network.host: 192.168.8.10,127.0.0.1
http.port: 9200
3.创建数据目录,并修改权限
mkdir -p /data/elasticsearch
chown -R elasticsearch.elasticsearch /data/elasticsearch/
4.分配锁定内存:
vim /etc/elasticsearch/jvm.options
-Xms1g #分配最小内存
-Xmx1g #分配最大内存,官方推荐为物理内存的一半,但最大为32G
5.修改锁定内存后,无法重启,解决方法如下:
systemctl edit elasticsearch
添加:
[Service]
LimitMEMLOCK=infinity
F2保存退出
systemctl daemon-reload
systemctl restart elasticsearch
6.查看
7.安装kibana
rpm -ivh kibana-6.6.0-x86_64.rpm
8.修改配置文件
vim /etc/kibana/kibana.yml
修改:
server.port: 5601
server.host: "192.168.8.10"
server.name: "db01" #自己所在主机的主机名
elasticsearch.hosts: ["http://192.168.8.10:9200"] #es服务器的ip,便于接收日志数据
保存退出
9.启动kibana
systemctl start kibana
10.配置yum源,安装 httpd-tools
yum -y install httpd-tools
11.使用ab压力测试工具测试访问
ab -c 1000 -n 10000 http://192.168.8.6/
12.在es浏览器查看filebeat索引和数据
13.在kibana添加索引
management--create index
discover--右上角--选择today
nginx主机:192.168.8.6
1.安装filebeat
rpm -ivh filebeat-6.6.0-x86_64.rpm
2.修改配置文件
vim /etc/filebeat/filebeat.ym
修改:
filebeat.inputs:
- type: log
enabled: true
paths:
- /var/log/nginx/access.log
output.elasticsearch:
hosts: ["192.168.8.5:9200"]
保存退出
3.启动filebeat
systemctl start filebeat
4.安装nginx并启动服务
5.修改nginx的日志格式为json
vim /etc/nginx/nginx.conf
添加在http {}内:
log_format log_json '{ "@timestamp": "$time_local", '
'"remote_addr": "$remote_addr", '
'"referer": "$http_referer", '
'"request": "$request", '
'"status": $status, '
'"bytes": $body_bytes_sent, '
'"agent": "$http_user_agent", '
'"x_forwarded": "$http_x_forwarded_for", '
'"up_addr": "$upstream_addr",'
'"up_host": "$upstream_http_host",'
'"up_resp_time": "$upstream_response_time",'
'"request_time": "$request_time"'
' }';
access_log /var/log/nginx/access.log log_json;
保存退出
systemctl restart nginx
6.清空日志:vim /var/log/nginx/access.log
ab测试访问,生成json格式日志
7.配置access.log和error.log分开
vim /etc/filebeat/filebeat.yml
修改为:
filebeat.inputs:
- type: log
enabled: true
paths:
- /var/log/nginx/access.log
json.keys_under_root: true
json.overwrite_keys: true
tags: ["access"]
- type: log
enabled: true
paths:
- /var/log/nginx/error.log
tags: ["error"]
output.elasticsearch:
hosts: ["192.168.8.5:9200"]
indices:
- index: "nginx-access-%{+yyyy.MM.dd}"
when.contains:
tags: "access"
- index: "nginx-error-%{+yyyy.MM.dd}"
when.contains:
tags: "error"
setup.template.name: "nginx"
setup.template.patten: "nginx-*"
setup.template.enabled: false
setup.template.overwrite: true
保存退出
重启服务:systemctl restart filebeat
登录kibana:
1.访问
2.登录--左侧面板选择visualize--点击“+”号--选择图表类型--选择索引--Buckets--x-Axis--Aggregation(选择Terms)--
Field(remote_addr.keyword)--size(5)--点击上方三角标志
kibana监控(x-pack):
登录--左侧面板选择--Monitoring--启用监控
8.Redis配置完成后修改filebeat配置文件,output给redis
vim /etc/filebeat/filebeat.yml
filebeat.inputs:
- type: log
enabled: true
paths:
- /var/log/nginx/access.log
json.keys_under_root: true
json.overwrite_keys: true
tags: ["access"]
- type: log
enabled: true
paths:
- /var/log/nginx/error.log
tags: ["error"]
setup.template.settings:
index.number_of_shards: 3
setup.kibana:
output.redis:
hosts: ["192.168.8.7"]
key: "filebeat"
db: 0
timeout: 5
保存退出
重启服务:systemctl restart filebeat
logstash主机192.168.8.7
1.安装redis,并启动
准备安装和数据目录
mkdir -p /data/soft
mkdir -p /opt/redis_cluster/redis_6379/{conf,logs,pid}
下载redis安装包
cd /data/soft
wget http://download.redis.io/releases/redis-5.0.7.tar.gz
2.解压redis到/opt/redis_cluster/
tar xf redis-5.0.7.tar.gz -C /opt/redis_cluster/
ln -s /opt/redis_cluster/redis-5.0.7 /opt/redis_cluster/redis
3.切换目录安装redis
cd /opt/redis_cluster/redis
make && make install
4.编写配置文件
vim /opt/redis_cluster/redis_6379/conf/6379.conf
添加:
bind 127.0.0.1 192.168.8.7
port 6379
daemonize yes
pidfile /opt/redis_cluster/redis_6379/pid/redis_6379.pid
logfile /opt/redis_cluster/redis_6379/logs/redis_6379.log
databases 16
dbfilename redis.rdb
dir /opt/redis_cluster/redis_6379
保存退出
5.启动当前redis服务
redis-server /opt/redis_cluster/redis_6379/conf/6379.conf
6.修改filebeat配置后登录redis
Es01上测试访问,redis查看
redis-cli #登录
keys * #列出所有键
type filebeat #filebeat为键值名
LLEN filebeat #查看list长度
LRANGE filebeat 0 -1 #查看list所有内容
7.安装logstash(安装包提前放在了/data/soft下)
cd /data/soft/
rpm -ivh logstash-6.6.0.rpm
8.修改logstash配置文件,实现access和error日志分离
注:mutate和grok是filter过滤选项,grok负责match正则过滤匹配,
mutate负责convert数据类型转换。
vim /etc/logstash/conf.d/redis.conf
添加:
input {
redis {
host => "192.168.8.7"
port => "6379"
db => "0"
key => "filebeat"
data_type => "list"
}
}
filter {
mutate {
convert => ["upstream_time","float"]
convert => ["request_time","float"]
}
}
output {
stdout {}
if "access" in [tags] {
elasticsearch {
hosts => ["http://192.168.8.5:9200"]
index => "nginx_access-%{+YYYY.MM.dd}"
manage_template => false
}
}
if "error" in [tags] {
elasticsearch {
hosts => ["http://192.168.8.5:9200"]
index => "nginx_error-%{+YYYY.MM.dd}"
manage_template => false
}
}
}
保存退出
重启logstash:
/usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/redis.conf
