为方便维护MySQL，写了个脚本用以提供收集错误信息的接口。这些错误信息来自与MySQL错误日志，而 通过grep mysql可以获取error-log的路径。

以下是全部相关代码：

#!/usr/bin/env python2.7#-*- encoding: utf-8 -*- """该模块用于提取每天mysql日志中的异常或错误信息author: xiaomoemail: moxiaomomo@gmail.com""" import osimport sysimport stringfrom datetime import * # 預設字符解碼器為utf-8reload(sys)sys.setdefaultencoding('utf-8')COMMON_FLAGS = ["error", "exception", "fail", "crash", "repair"] def _contain_flag(cur_str):for flag in COMMON_FLAGS:if flag in string.lower(cur_str):return Truereturn False """获取当前mysql实例的error_log文件路径"""def _get_mysql_error_log_path():log_path = ''grep_infos = os.popen('ps aux | grep mysql | grep "log-error"').read()if len(grep_infos) > 1:grep_infos = grep_infos.split("log-error=")if len(grep_infos) > 1:grep_infos = grep_infos[1].split(' ')if len(grep_infos) > 1:log_path = grep_infos[0]return log_path """读取mysql错误日志中包含异常或错误信息的行"""def _get_error_info(error_log, begin_date):error_infos = []f = open(error_log, 'r')lines = f.readlines()for line in lines:data_array = line.split(' ')if len(data_array) > 0 and len(data_array[0]) == 10:dt_strs = data_array[0].split('-')cur_date = date(int(dt_strs[0]), int(dt_strs[1]), int(dt_strs[2]))if cur_date >= begin_date and _contain_flag(line):error_infos.append(line)f.close()return error_infos """组装并返回mysql错误日志信息"""def get_mysql_errors(begin_date=date.today()-timedelta(1)):try:err_log_path = _get_mysql_error_log_path()if len(err_log_path) > 1:return _get_error_info(err_log_path, begin_date)except Exception,e:print "[get_mysql_errors]%s"%ereturn []
