解压logstash

tar zxvf src/logstash-6.5.1.tar.gz
vim logstash-6.5.1/config/std_test.conf            //新建测试conf
input {
    stdin{
    }
} 

output {
    stdout{
    }
}

测试

./logstash-6.5.1/bin/logstash -f logstash-6.5.1/config/std_test.conf        //启动测试，如果出现下列字符就表示安装安装成功

新建调用nginx日志的配置文件

input {
	file{
	path =>"/home/yx/server/nginx/logs/*.log"            #通配符*号
	start_position=>"beginning"
	}
}

filter{
	grok{
		patterns_dir => "*.log"                            #通配符*号
		match=>{"message"=>"%{DATA:clientIp} - - \[%{HTTPDATE:accessTime}\] \"%{DATA:method} %{DATA:requestPath} %{DATA:httpversion}\" %{DATA:retcode} %{DATA:size} \"%{DATA:fromHtml}\" \"%{DATA:useragent}\""                #具体各项配置详解可参考链接：http://udn.yyuap.com/doc/logstash-best-practice-cn/index.html
		}
		remove_field=>"message"
	}
	date{
		match=>["accessTime","dd/MMM/yyyy:HH:mm:ss Z"]
	}
}
output {
    stdout{
    	codec=>rubydebug
    }
}

新建调用PHP日志的配置文件，只有input的输入路径不同，其他都一样。

input {
	file{
	path =>"/home/yx/server/php56/log/php-error.log"        #单个日志例子
	start_position=>"beginning"
	}
}

filter{
	grok{
		patterns_dir => "*.log"
		match=>{"message"=>"%{DATA:clientIp} - - \[%{HTTPDATE:accessTime}\] \"%{DATA:method} %{DATA:requestPath} %{DATA:httpversion}\" %{DATA:retcode} %{DATA:size} \"%{DATA:fromHtml}\" \"%{DATA:useragent}\""
		}
		remove_field=>"message"
	}
	date{
		match=>["accessTime","dd/MMM/yyyy:HH:mm:ss Z"]
	}
}
output {
    stdout{
    	codec=>rubydebug
    }
}

指定多配置文件启动，个人感觉也可以将所有需显示的日志软连接到一个单独目录里，然后配置文件只写一个就好。

./logstash-6.5.1/bin/logstash -f logstash-6.5.1/config/std_nginx.conf -f logstash-6.5.1/config/std_php.conf     //前台启动，可以实时查看日志输出。
nohup ./logstash-6.5.1/bin/logstash -f logstash-6.5.1/config/std_nginx.conf -f logstash-6.5.1/config/std_php.conf & //后台启动并且不会影响输出。

此处可以另开两个窗口，tail -f  查看nginx的日志和PHP的日志，从而和logstash输出的日志做对比。

如果没有意外，到此logstash已经安装成功。请看第二篇
