执行 datax 作业,创建执行文件,在 crontab 中每天1点(下面有关系)执行:
其中 job_start 及 job_finish 这两行记录是自己添加的,为了方便识别出哪张表。
#!/bin/bash source /etc/profile user1="root" pass1="pwd" user2="root" pass2="pwd" job_path="/opt/datax/job/" jobfile=( job_table_a.json job_table_b.json ) for filename in ${jobfile[@]} do echo "job_start: "`date "+%Y-%m-%d %H:%M:%S"`" ${filename}" python /opt/datax/bin/datax.py -p "-Duser1=${user1} -Dpass1=${pass1} -Duser2=${user2} -Dpass2=${pass2}" ${job_path}${filename} echo "job_finish: "`date "+%Y-%m-%d %H:%M:%S"`" ${filename}" done # 0 1 * * * /opt/datax/job/dc_to_ods_incr.sh >> /opt/datax/job/log/dc_to_ods_incr_$(date +\%Y\%m\%d_\%H\%M\%S).log 2>&1 # egrep '任务|速度|总数|job_start|job_finish' /opt/datax/job/log/
datax 执行日志:
job_start: 2018-08-08 01:13:28 job_table_a.json 任务启动时刻 : 2018-08-08 01:13:28 任务结束时刻 : 2018-08-08 01:14:49 任务总计耗时 : 81s 任务平均流量 : 192.82KB/s 记录写入速度 : 1998rec/s 读出记录总数 : 159916 读写失败总数 : 0 job_finish: 2018-08-08 01:14:49 job_table_a.json job_start: 2018-08-08 01:14:49 job_table_b.json 任务启动时刻 : 2018-08-08 01:14:50 任务结束时刻 : 2018-08-08 01:15:01 任务总计耗时 : 11s 任务平均流量 : 0B/s 记录写入速度 : 0rec/s 读出记录总数 : 0 读写失败总数 : 0 job_finish: 2018-08-08 01:15:01 job_table_b.json
接下来读取这些信息保存到数据库,在数据库中创建表:
CREATE TABLE `datax_job_result` ( `log_file` varchar(200) DEFAULT NULL, `job_file` varchar(200) DEFAULT NULL, `start_time` datetime DEFAULT NULL, `end_time` datetime DEFAULT NULL, `seconds` int(11) DEFAULT NULL, `traffic` varchar(50) DEFAULT NULL, `write_speed` varchar(50) DEFAULT NULL, `read_record` int(11) DEFAULT NULL, `failed_record` int(11) DEFAULT NULL, `job_start` varchar(200) DEFAULT NULL, `job_finish` varchar(200) DEFAULT NULL, `insert_time` datetime DEFAULT CURRENT_TIMESTAMP ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
定时执行以下文件,因为 datax 作业 1 点执行,为了获取一天内最新生产的日志,脚本中取 82800内生产的日志文件,及23 小时内生产的那个最新日志。所以一天内任何时间执行都可以。此文件也是定时每天执行(判断 datax 作业完成后执行)
