使用hive分析nginx访问日志方法

以下案例是使用hive分析nginx的访问日志案例，其中字段分隔通过正则表达式匹配，具体步骤如下：

日志格式：

正则匹配：

([^ |^\n]*) ([^ ]*) ([^ ]*) (\[.*\]) (\".*?\") (-|[0-9]*) (-|[0-9]*) (\".*?\") (\".*?\") (-)

 

建立原表：

drop table if exists chavin.nginx_access_log;
CREATE TABLE chavin.nginx_access_log(
   host STRING,
   identity STRING,
   user STRING,
   time STRING,
   request STRING,
   status STRING,
   size STRING,
   referer STRING,
   agent STRING,
   other STRING)
ROW FORMAT SERDE 'org.apache.hadoop.hive.contrib.serde2.RegexSerDe'
WITH SERDEPROPERTIES (
   "input.regex" = "([^ |^\n]*) ([^ ]*) ([^ ]*) (\\[.*\\]) (\".*?\") (-|[0-9]*) (-|[0-9]*) (\".*?\") (\".*?\") (-)",
   "output.format.string" = "%1$s %2$s %3$s %4$s %5$s %6$s %7$s %8$s %9$s %10$s"
)
STORED AS TEXTFILE;

 

清除access.log日志中空白行：

sed -i '/^$/d' access.log

 

加载access.log日志数据到hive中：

load data local inpath '/opt/datas/access.log' overwrite into table chavin.nginx_access_log;

查询数据，进行验证：

select * from chavin.nginx_access_log limit 5;

接下来可以建立业务子表，进行定向分析了。
