MySQL server has gone away and maximum execution time of seconds exceeded

I had two problems writing a collection today.
1. MySQL server has gone away
2. Maximum execution time of seconds exceeded

The capture program is written to run about a minute after the MySQL server has gone away, found that MySQL inside the max_allowed_packet = 1M, here changed to 10M, After running for two minutes maximum execution time of seconds exceeded, here is because php.ini set the max_execution_time=120，把这里的120改成0就是永不过期。运行没有再出问题
