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/jdbc
cd /usr/share/logstash/vendor/jar/jdbc
[root@localhost soft]# cd /usr/share/logstash/vendor/jar/jdbc
[root@localhost jdbc]# ll
total 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-jdbc
Installing logstash-output-jdbc
Installation successful
 
/usr/share/logstash/bin/logstash-plugin list | grep jdbc
logstash-input-jdbc
logstash-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
