如何使用logstash同步nginx日志到数据库

概述

logstash

logstash就是一根具备实时数据传输能力的管道，负责将数据信息从管道的输入端传输到管道的输出端；与此同时这根管道还可以让你根据自己的需求在中间加上滤网，Logstash提供里很多功能强大的滤网以满足你的各种应用场景。

Nginx

Nginx(engine x) 是一个高性能的HTTP和反向代理服务器，也是一个IMAP/POP3/SMTP服务器。其将源代码以类BSD许可证的形式发布，因它的稳定性、丰富的功能集、示例配置文件和低系统资源的消耗而闻名。Nginx是一款轻量级的Web服务器/反向代理服务器及电子邮件（IMAP/POP3）代理服务器，并在一个BSD-like 协议下发行。其特点是占有内存少，并发能力强，事实上nginx的并发能力确实在同类型的网页服务器中表现较好。

1.logstash安装（jdk提前安装1.8）

rpm -ivh logstash-6.6.2.rpm

2.上传数据库驱动jar包

wget https://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.48.tar.gz

mkdir -p /usr/share/logstash/vendor/jar/jdbccd /usr/share/logstash/vendor/jar/jdbc[root@localhost soft]# cd /usr/share/logstash/vendor/jar/jdbc[root@localhost jdbc]# lltotal 984-rw-r--r--. 1 logstash logstash 1006959 Jul 11 19:43 mysql-connector-java-5.1.48-bin.jar[root@localhost jdbc]#

3.数据库创建库 并授权用户

create database nginxlog;use nginxlog;CREATE TABLE `consumerlog` (  `client_ip` varchar(128) DEFAULT NULL,  `log_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,  `status` int(6) DEFAULT NULL,  `http_referer` text,  `AgentVersion` varchar(512) DEFAULT NULL,) grant all  on  nginxlog.* to  nginxlog@'%'  identified  by  '123456';

4.安装 logstash-output-jdbc插件

vim /usr/share/logstash/Gemfile# source "https://rubygems.org"  将国外的源注释,换成国内的source "https://gems.ruby-china.com/"/usr/share/logstash/bin/logstash-plugin install logstash-output-jdbc

Validating logstash-output-jdbcInstalling logstash-output-jdbcInstallation successful /usr/share/logstash/bin/logstash-plugin list | grep jdbclogstash-input-jdbclogstash-output-jdbc

5.nginx日志格式设置

log_format   access_log_json '{"client_ip":"$remote_addr","log_time":"$time_local","request":"$request","status":"$status","body_bytes_sent":"$body_bytes_sent","http_referer":"$http_referer","AgentVersion":"$http_user_agent","upstream_addr":"$upstream_addr","request_time":"$request_time","upstream_response_time":"$upstream_response_time"}';

6.

[root@localhost conf.d]# cat consumer_log.conf

/etc/logstash/conf.d

input{  file{    path => "/usr/local/tengine-2.1.2/logs/sxt-consumer.log"    start_position => "beginning"    stat_interval => "2"    codec => "json"  } } filter {    if [status] != "200" {         drop{}    }}output{  jdbc{    connection_string => "jdbc:mysql://192.168.14.61/nginxlog?user=nginxlog&password=123456&useUnicode=true&characterEncoding=UTF8"    statement => ["insert into consumerlog(client_ip,status,http_referer,AgentVersion) VALUES(?,?,?,?)", "client_ip","status","http_referer","AgentVersion"] }}

7.启动logstash

systemctl start logstash

8.验证数据
