3、filebeat配置
3.1 mysql+filebeat（ip：10.8.156.177）
3.1.1 安装mysql（略）
3.1.2 安装配置filebeat
[root@mysql ~]# tar xzf filebeat-7.8.0-linux-x86_64.tar.gz -C /usr/local
[root@mysql ~]# mv /usr/local/filebeat-7.8.0-linux-x86_64 /usr/local/filebeat
[root@mysql ~]# cd /usr/local/filebeat
[root@mysql filebeat]# mv filebeat.yml filebeat.yml.bak
[root@mysql filebeat]# vim filebeat.yml
filebeat.inputs:
- input_type: log
paths:
- /var/lib/mysql/*.log
#json.keys_under_root: true
#json.add_error_key: true
#json.message_key: log
output.kafka:
hosts: ["10.8.156.176:9092","10.8.156.186:9092","10.8.156.183:9092","10.8.156.179:9092"]
topic: 'mysql'
说明：
#json.keys_under_root: true
#json.add_error_key: true
#json.message_key: log
这三行是识别json格式日志的配置，若日志格式不为json格式，需要注释掉，否则收集到的日志为filebeat的错误日志
[root@mysql filebeat]# nohup ./filebeat -e -c filebeat.yml &

-Xms1g ----修改成 -Xms2g
-Xmx1g ----修改成 -Xms2g
注意：
确保堆内存最小值（Xms）与最大值（Xmx）的大小相同，防止程序在运行时改变堆内存大小。堆内存大小不要超过系统内存的50%
6.5 创建ES数据及日志存储目录（三台）
[root@mes-1 ~]# mkdir -p /data/elasticsearch/data
[root@mes-1 ~]# mkdir -p /data/elasticsearch/logs

* soft nofile 65536
* hard nofile 65536
* soft nproc 2048
* hard nproc 4096
#增加最大内存映射数（在内存不足的情况下，使用交换空间）
[root@mes-1 ~]# vim /etc/sysctl.conf ---添加如下
vm.max_map_count=262144
vm.swappiness=0
[root@mes-1 ~]# sysctl -p
或
[root@mes-1 ~]# sysctl -w vm.max_map_count=262144 ---增大用户使用内存的空间(临时)
6.7 启动ES（三台）
[root@mes-1 ~]# su - elsearch
[root@mes-1 elasticsearch-7.8.0]$ nohup ./bin/elasticsearch & #放后台启动
[root@mes-1 elasticsearch-7.8.0]$ tail -f nohup.out #看一下是否启动

7、kibana+head（ip：10.8.156.168）
7.1 安装配置head监控插件
7.1.1 安装node
[root@kibana ~]# wget https://npm.taobao.org/mirrors/node/latest-v4.x/node-v4.4.7-linux-x64.tar.gz
[root@kibana ~]# tar -zxf node-v4.4.7-linux-x64.tar.gz –C /usr/local //head运行依赖于node环境
[root@kibana ~]# vim /etc/profile #添加如下变量
NODE_HOME=/usr/local/node-v4.4.7-linux-x64
PATH=$NODE_HOME/bin:$PATH
export NODE_HOME PATH
[root@kibana ~]# source /etc/profile
[root@kibana ~]# node --version #检查node版本号
v4.4.7
7.1.2 下载head插件
[root@kibana ~]# wget https://github.com/mobz/elasticsearch-head/archive/master.zip
[root@kibana ~]# cp master.zip /usr/local/
[root@kibana ~]# yum -y install unzip //有的话就不用下载
[root@kibana ~]# cd /usr/local
[root@kibana local]# unzip master.zip
7.1.3 安装grunt
[root@kibana ~]# cd elasticsearch-head-master/
[root@kibana ~]# npm config set registry https://registry.npm.taobao.org
[root@kibana elasticsearch-head-master]# npm install -g grunt-cli #时间会很长
[rootlocalhost elasticsearch-head-master]# grunt --version #检查grunt版本号
grunt-cli v1.3.2
7.1.4 修改head源码
[root@kibana elasticsearch-head-master]# vim /usr/local/elasticsearch-head-master/Gruntfile.js
image.png
添加hostname，注意在上一行末尾添加逗号,hostname 不需要添加逗号
[root@kibana elasticsearch-head-master]# vim /usr/local/elasticsearch-head-master/_site/app.js
image.png
7.1.5 下载head必要的文件
[root@kibana ~]# wget https://github.com/Medium/phantomjs/releases/download/v2.1.1/phantomjs-2.1.1-linux-x86_64.tar.bz2
[root@kibana ~]# yum -y install bzip2
[root@kibana ~]# tar -jxf phantomjs-2.1.1-linux-x86_64.tar.bz2 -C /tmp/ #解压
7.1.6 运行head
[root@kibana ~]# cd /usr/local/elasticsearch-head-master/
[root@kibana elasticsearch-head-master]# npm config set registry https://registry.npm.taobao.org
[root@kibana elasticsearch-head-master]# npm install
[root@kibana elasticsearch-head-master]# nohup grunt server &
[root@kibana elasticsearch-head-master]# tailf nohup.out
Running "connect:server" (connect) task
Waiting forever...
Started connect web server on http://localhost:9100
7.1.7 测试
访问head插件10.8.156.168:9100
image.png
7.2 kibana部署
7.2.1 安装
[root@kibana ~]# tar -xvzf kibana-7.8.0-linux-x86_64.tar.gz -C /usr/local/
7.2.2 配置
[root@kibana ~]# cd /usr/local/kibana-7.8.0-linux-x86_64.tar.gz/config/
[root@kibana config]# vim kibana.yml
server.port: 5601
server.host: "10.8.156.168" #kibana本机的地址
elasticsearch.hosts: "http://10.8.156.166:9200" #ES主节点地址+端口
kibana.index: ".kibana"
7.2.3 启动
[root@kibana config]# cd ..
[root@kibana kibana-7.8.0-linux-x86_64]# nohup ./bin/kibana --allow-root &
[1] 12054
[root@kibana kibana-7.8.0-linux-x86_64]# tail -f nohup.out
注意：#7.8版本的kibana启动：不可以使用root用户启动，若要使用root用户启动：nohup ./bin/kibana --allow-root &
7.3 安装配置nginx反向代理
#安装nginx
[root@kibana ~]# yum -y install epel-release;yum install -y nginx
#配置反向代理 （为了访问时地址后面不用写端口号，可以直接用IP进行访问）
先把/etc/nginx/nginx.conf 里的server模块注释掉
[root@kibana ~]# cd /etc/nginx/conf.d/
[root@kibana conf.d]# mv default.conf default.conf.bak
[root@kibana conf.d]# vim default.conf
server {
listen 80;
server_name 10.8.156.168;
#charset koi8-r;
# access_log /var/log/nginx/host.access.log main;
# access_log off;
location / {
proxy_pass http://10.8.156.168:5601;
proxy_set_header Host $host:5601;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Via "nginx";
}
location /status {
stub_status on; #开启网站监控状态
access_log /var/log/nginx/kibana_status.log; #监控日志
auth_basic "NginxStatus"; }
location /head/{
proxy_pass http://10.8.156.168:9100;
proxy_set_header Host $host:9100;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Via "nginx";
}
}
#配置nginx日志格式
1.将原来的log_format注释掉，添加json格式的配置信息，如下：
[root@kibana conf.d]# vim /etc/nginx/nginx.conf
log_format json '{"@timestamp":"$time_iso8601",'
'"@version":"1",'
'"client":"$remote_addr",'
'"url":"$uri",'
'"status":"$status",'
'"domain":"$host",'
'"host":"$server_addr",'
'"size":$body_bytes_sent,'
'"responsetime":$request_time,'
'"referer": "$http_referer",'
'"ua": "$http_user_agent"'
'}';
2.引用定义的json格式的日志：
access_log /var/log/nginx/access_json.log json;
image.png
启动nginx
systemctl start nginx
8、验证
查看head上是否出现索引
image.png
然后去kibana上面添加索引

image.png
image.png
日志收集成功，依次添加Tomcat、mysql、nginx索引，并查看日志
