[ELK] Nginx 监控

一、安装nginx 1.11.10
#yum -y install zlib zlib-devel openssl openssl-devel pcre pcre-devel
# cd/usr/local/src
#tar -zxvf nginx-1.11.10.tar.gz
# cdnginx-1.11.10
#./configure --prefix=/usr/local/nginx
# make&& make install
 
#/usr/local/nginx/sbin/nginx-t     #测试
 
 
二、修改nginx日志格式
# vi/usr/local/nginx/conf/nginx.conf

#user  nobody; worker_processes  1;   #error_log  logs/error.log; #error_log  logs/error.log  notice; #error_log  logs/error.log  info;   #pid        logs/nginx.pid;     events {     worker_connections  1024; }     http {     include       mime.types;     default_type  application/octet-stream;       #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '     log_format json '{"@timestamp":"$time_iso8601",'        #修改为json格式                '"@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":"$http_user_agent"'                '}';     #                  '$status $body_bytes_sent "$http_referer" '     #                  '"$http_user_agent" "$http_x_forwarded_for"';       #access_log  logs/access.log  main;           #这一行要注释       sendfile        on;     #tcp_nopush     on;       #keepalive_timeout  0;     keepalive_timeout  65;       #gzip  on;       server {         listen       80;         server_name  localhost;           #charset koi8-r;           #access_log  logs/host.access.log  main;         access_log /var/log/nginx/access_json.log json;            #log日志定义放在server{}中           location / {             root   html;             index  index.html index.htm;         }           #error_page  404              /404.html;           # redirect server error pages to the static page /50x.html         #         error_page   500 502 503 504  /50x.html;         location = /50x.html {             root   html;         }           # proxy the PHP scripts to Apache listening on 127.0.0.1:80         #         #location ~ \.php$ {         #    proxy_pass  http://127.0.0.1;         #}           # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000         #         #location ~ \.php$ {         #    root           html;         #    fastcgi_pass   127.0.0.1:9000;         #    fastcgi_index  index.php;         #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;         #    include        fastcgi_params;         #}           # deny access to .htaccess files, if Apache's document root         # concurs with nginx's one         #         #location ~ /\.ht {         #    deny  all;         #}     }         # another virtual host using mix of IP-, name-, and port-based configuration     #     #server {     #    listen       8000;     #    listen       somename:8080;     #    server_name  somename  alias  another.alias;       #    location / {     #        root   html;     #        index  index.html index.htm;     #    }     #}         # HTTPS server     #     #server {     #    listen       443 ssl;     #    server_name  localhost;       #    ssl_certificate      cert.pem;     #    ssl_certificate_key  cert.key;       #    ssl_session_cache    shared:SSL:1m;     #    ssl_session_timeout  5m;       #    ssl_ciphers  HIGH:!aNULL:!MD5;     #    ssl_prefer_server_ciphers  on;       #    location / {     #        root   html;     #        index  index.html index.htm;     #    }     #}   }

 
 
 
三、启动nginx
#/usr/local/nginx/sbin/nginx

 
四、编写logstash conf文件
input {
 
    file {                                                                              # file插件
        path =>"/var/log/nginx/access_json.log"          #日志
        type =>"nginx"                                                       #定义类型，在输出中可以用做if判断
        start_position =>"beginning"                              #string,
one of ["beginning", "end"]。默认为end
        codec => json                                                          #格式为json
    }
 
}
 
output {
   elasticsearch {                                               
          hosts =>["192.168.1.75:9200"]                        #定义输出ip：port
          index =>"nginx-%{+YYYY.MM.dd}"                  #定义索引，这个在head/kopf/kibana可以方便查询
    }
 
}
