Answer 1

For

121226 13:12:06  InnoDB: The InnoDB memory heap is disabled

you can try set innodb_use_sys_malloc = 0 in my.cnf . More reference documentation is here .

Also:

• you can try clear contents of mysql-bin.index . Related question is here .

• if you have some antivirus/firewall software, try turn it off and check the functionality, bec. it can be the reason of some issues.

Answer 2

What i think the problem might be is .

1. give MySql access to the firewall fix this
2. you should allow MySQL server (mysqld.exe) to start and allow access to port 3306.
3. Try to decrease innodb_buffer_pool_size in my.ini file then. Set it to 1G and check if this will allow service to start.

note mysql uses tcp connection
