ELK实战之收集Nginx的json格式日志

一、安装Nginx

[root@linux-node1 ~]# yum install nginx -y
[root@linux-node1 ~]# vim /etc/nginx/nginx.conf
#修改日志格式为json格式，并创建一个nginxweb的网站目录
log_format access_json '{"@timestamp":"$time_iso8601",'
'"host":"$server_addr",'
'"clientip":"$remote_addr",'
'"size":$body_bytes_sent,'
'"responsetime":$request_time,'
'"upstreamtime":"$upstream_response_time",'
'"upstreamhost":"$upstream_addr",'
'"http_host":"$host",'
'"url":"$uri",'
'"domain":"$host",'
'"xff":"$http_x_forwarded_for",'
'"referer":"$http_referer",'
'"status":"$status"}';
access_log  /var/log/nginx/access.log  access_json;

location /nginxweb {
root html;
index index.html index.htm;
}
[root@linux-node1 ~]# mkdir /usr/share/nginx/html/nginxweb
[root@linux-node1 ~]# echo "<h1> welcome to use Nginx" > /usr/share/nginx/html/nginxweb/index.html
[root@linux-node1 ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@linux-node1 ~]# systemctl start nginx

二、配置logstash

[root@linux-node1 ~]# vim /etc/logstash/conf.d/nginx-accesslog.conf
input{
file {
path => "/var/log/nginx/access.log"
type => "nginx-access-log"
start_position => "beginning"
stat_interval => "2"
}

}

output{
elasticsearch {
hosts => ["192.168.56.11:9200"]
index => "logstash-nginx-access-log-%{+YYYY.MM.dd}"
}
file {
path => "/tmp/logstash-nginx-access-log-%{+YYYY.MM.dd}"
}
}
[root@linux-node1 ~]# /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/nginx_access.conf -t
[root@linux-node1 ~]# systemctl restart logstash

三、配置Kibana展示

[root@linux-node1 ~]# ab -n1000 -c 100 http://192.168.56.11/nginxweb/index.html    #对页面压测
[root@linux-node1 ~]# tailf /var/log/nginx/access.log    #nginx的访问日志变成了json格式
