1、回顾昨天(索引优化）
1. 按照我们想要的效果生成索引
- 自定索引名称
- 按月生成
- 按域名和访问类型创建索引
- 能够索引日志里的 每个字内容
2. filebeat设置
- nginx格式修改为json
- filebeate添加模板相关选项
setup.template.name: "nginx"
setup.template.pattern: "nginx_*"
setup.template.enabled: false
setup.template.overwrite: true
- filebeat添加参数直接解析成json格式
json.keys_under_root: true
json.overwrite_keys: true
- filebeat的input添加tags标签
tags["www"]
- filwbeat的output里判断tags
- index: "nginx_www_access-%{[beat.version]}-%{+yyyy.MM}"
when.contains:
tags: "www"
3. 收集tomcat日志
- 安装tomcat并访问，产生数据
- 修改tomcat日志为json格式，139行替换
- 验证tomcat日志是否为json格式
- filebeat配置
-- 使用*来匹配tomcat每天生成的日志
- type: log
4. 收集java多行日志
- filebeat配置java日志路径
- 添加3行多行匹配的参数
- type: log
enabled: true
paths:
- /var/log/elasticsearch/linux58.log
tags: ["java"]
multiline.pattern: '^\['
multiline.negate: true
multiline.match: after
5.kibana画图展示
- 柱状图，饼图，仪表图，折线图，Data Table,markdown
- Dashboard大屏实时展示
- 查询时间要注意，查询条件对面板也是生效的
- 画完记得保存
- 别把es里的.kibana给删了
2、ELk filebeat modules
filebeat是go语言编写
- 快，不依赖于java环境
配置步骤：
1.配置相关modules参数
filebeat.config.modules:
path: ${path.config}/modules.d/*.yml
reload.enabled: true
reload.period: 10s
2.查看模块
filebeat modules list
3.激活模块
[root@db01 ~]# filebeat modules enable nginx
Enabled nginx
4.修改nginx为普通日志格式
5.修改filebeat配置文件
不足的地方：
1.错误日志和正确日志都混在一起了
2.不能按域名生成索引
2.1、filebeat modules 自定义索引和视图
1.为了不影响实验，建议删除所有其他的索引
systemctl stop elasticsearch
systemctl stop kibana
rm -rf /data/elasticsearch/*
rm -rf /var/lib/kibana/*
systemctl start elasticsearch
systemctl start kibana
2.修改nginx配置文件
sed -i 's#json#main#g' /etc/nginx/conf.d/bbs.conf
3.清空nginx日志
> /var/log/nginx/bbs_access.log
4.重启nginx
systemctl restart nginx
5.修改filebeat配置文件:
filebeat.config.modules:
path: ${path.config}/modules.d/*.yml
reload.enabled: true
setup.kibana:
host: "10.0.0.51:5601"
output.elasticsearch:
hosts: ["10.0.0.51:9200"]
indices:
- index: "nginx_bbs_access-%{[beat.version]}-%{+yyyy.MM}"
when.contains:
source: "/var/log/nginx/bbs_access.log"
- index: "nginx_error-%{[beat.version]}-%{+yyyy.MM}"
when.contains:
fileset.name: "error"
setup.template.name: "nginx"
setup.template.pattern: "nginx_*"
setup.template.enabled: false
setup.template.overwrite: true
6.激活nginx模块报错
filebeat modules enable nginx
7.安装nginx modules插件
/usr/share/elasticsearch/bin/elasticsearch-plugin install file:///root/ingest-geoip-6.6.0.zip /usr/share/elasticsearch/bin/elasticsearch-plugin install file:///root/ingest-user-agent-6.6.0.zip
8.重启es
systemctl restart elasticsearch
9.修改模块配置
[root@db01 ~]# egrep -v "#|^$" /etc/filebeat/modules.d/nginx.yml
- module: nginx
access:
enabled: true
var.paths: ["/var/log/nginx/bbs_access.log"]
error:
enabled: true
var.paths: ["/var/log/nginx/error.log"]
10.备份删除不必要的视图文件并导入到kibana
cp -a /usr/share/filebeat/kibana /root
cd /usr/share/filebeat/kibana/6/dashboard
find . -type f ! -name "*nginx*"|xargs rm -rf
rm -rf ml-nginx-*
sed -i 's#filebeat\-\*#nginx\_\*#g' Filebeat-nginx-logs.json
sed -i 's#filebeat\-\*#nginx\_\*#g' Filebeat-nginx-overview.json
cd index-pattern/
sed -i 's#filebeat\-\*#nginx\_\*#g' filebeat.json
filebeat setup --dashboards -E setup.dashboards.directory=/root/kibana/
rm -rf /var/lib/kibana/*
systemctl restart kibana
3、安装docker步骤
安装docker步骤
rm -fr /etc/yum.repos.d/local.repo
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
wget -O /etc/yum.repos.d/docker-ce.repo https://mirrors.ustc.edu.cn/docker-ce/linux/centos/docker-ce.repo
sed -i 's#download.docker.com#mirrors.tuna.tsinghua.edu.cn/docker-ce#g' /etc/yum.repos.d/docker-ce.repo
yum install docker-ce -y
systemctl start docker
cat > /etc/docker/daemon.json <<EOF
{
"registry-mirrors": ["https://registry.docker-cn.com"]
}
EOF
systemctl restart docker
下载镜像
docker pull nginx
docker run --name nginx -p 80:80 -d nginx
docker ps
docker logs -f nginx
镜像：模板
容器：以什么模板启动的微型linux
docker pull 镜像名:版本：拉去镜像
docker rmi 镜像名或id：删除镜像
docker images：获取本地已有镜像
docker run 镜像名或id：使用默认端口启动镜像
docker run -p port:port1 -d 镜像名或id：指定port端口映射到port1，并后台启动镜像
进入容器内部 docker exec -it nginx容器ID /bin/bash
docker ps：查看正在运行的docker容器
docker ps -a：查看所有执行过run命令的容器服务（包括已经停止的容器）
docker stop 容器id：停止某个容器
docker restart 容器id：重启某个容器
docker rm 容器Id：删除某个容器
docker exec -it nginx /bin/bash
3.1、收集docker容器日志
1.生成多个容器
systemctl stop nginx
docker stop $(docker ps -q)
docker rm $(docker ps -aq)
docker commit nginx nginx:v2
docker run --name nginx -p 80:80 -d nginx
docker run --name mysql -p 8080:80 -d nginx:v2
docker images
docker ps
docker logs -f nginx
docker logs -f mysql
2.修改filebeat配置文件
filebeat.inputs:
- type: docker
containers.ids:
- '*'
filebeat.config.modules:
path: ${path.config}/modules.d/*.yml
reload.enabled: false
setup.kibana:
host: "10.0.0.51:5601"
output.elasticsearch:
hosts: ["10.0.0.51:9200"]
index: "docker-nginx-%{[beat.version]}-%{+yyyy.MM}"
setup.template.name: "docker"
setup.template.pattern: "docker-*"
setup.template.enabled: false
setup.template.overwrite: true
3.重启filebeat
systemctl restart filebeat
3.2、按服务类型拆分docker容器日志
1.安装docker-compose
yum install -y python2-pip
2.这里使用pip安装，默认源为国外，可以使用国内加速，相关网站
https://mirrors.tuna.tsinghua.edu.cn/help/pypi/
pip加速操作命令
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pip -U
pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
3.继续安装docker-compose
pip install docker-compose
4.检查版本
docker-compose version
5.创建docker-compose配置文件
[root@db03 ~]# cat docker-compose.yml
version: '3'
services:
nginx:
image: nginx:latest
#设置labels
labels:
service: nginx
#logging设置增加labels.service
logging:
options:
labels: "service"
ports:
- "80:80"
mysql:
image: nginx:v2
#设置labels
labels:
service: mysql
#logging设置增加labels.service
logging:
options:
labels: "service"
ports:
- "8080:80"
6.使用docker-compose启动docker
docker stop $(docker ps -q)
docker rm $(docker ps -aq)
docker-compose up -d
docker ps
7.修改filebeat配置文件
filebeat.inputs:
- type: log
enabled: true
paths:
- /var/lib/docker/containers/*/*-json.log
json.keys_under_root: true
json.overwrite_keys: true
setup.kibana:
host: "10.0.0.51:5601"
output.elasticsearch:
hosts: ["10.0.0.51:9200"]
indices:
- index: "docker-nginx-access-%{[beat.version]}-%{+yyyy.MM}"
when.contains:
attrs.service: "nginx"
stream: "stdout"
- index: "docker-nginx-error-%{[beat.version]}-%{+yyyy.MM}"
when.contains:
attrs.service: "nginx"
stream: "stderr"
- index: "docker-mysql-access-%{[beat.version]}-%{+yyyy.MM}"
when.contains:
attrs.service: "mysql"
stream: "stdout"
- index: "docker-mysql-error-%{[beat.version]}-%{+yyyy.MM}"
when.contains:
attrs.service: "mysql"
stream: "stderr"
setup.template.name: "docker"
setup.template.pattern: "docker-*"
setup.template.enabled: false
setup.template.overwrite: true
4、filebeat和logstash配置
filebeat存入redis，logstash从redis读取数据
#filebeat配置
filebeat.inputs:
- type: log
enabled: true
paths:
- /var/log/nginx/bbs_access.log
json.keys_under_root: true
json.overwrite_keys: true
tags: ["bbs"]
- type: log
enabled: true
paths:
- /var/log/nginx/www_access.log
json.keys_under_root: true
json.overwrite_keys: true
tags: ["www"]
setup.kibana:
host: "10.0.0.51:5601"
output.redis:
hosts: ["localhost"]
keys:
- key: "bbs"
when.contains:
tags: "bbs"
- key: "www"
when.contains:
tags: "www"
db: 0
timeout: 5
setup.template.name: "nginx"
setup.template.pattern: "nginx-*"
setup.template.enabled: false
setup.template.overwrite: true
#redis查看命令
redis-cli
keys *
llen bbs
llen www
#logstash配置
[root@db01 /data/soft]# cat /etc/logstash/conf.d/redis.conf
input {
redis {
host => "127.0.0.1"
port => "6379"
db => "0"
key => "bbs"
data_type => "list"
}
redis {
host => "127.0.0.1"
port => "6379"
db => "0"
key => "www"
data_type => "list"
}
}
#filter {
# mutate {
# convert => ["upstream_time", "float"]
# convert => ["request_time", "float"]
# }
#}
output {
if "bbs" in [tags] {
stdout {}
elasticsearch {
hosts => "http://10.0.0.51:9200"
manage_template => false
index => "nginx-bbs-%{+yyyy.MM}"
}
}
if "www" in [tags] {
stdout {}
elasticsearch {
hosts => "http://10.0.0.51:9200"
manage_template => false
index => "nginx-www-%{+yyyy.MM}"
}
}
}
#logstash启动命令
/usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/redis.conf
