my.cnf

In MySQL you can set a session variable called time_zone to change the timezone. This is useful e.g. when looking at timestamps from another country. Here is an example: mysql> select now(); +---------------------+ | now() | +---------------------+ | 2010-12-30 18:59:18 | +---------------------+ 1 row in set (0.00 sec) mysql> set time_zone='Brazil/East'; Query OK, 0 rows affected (0.00 sec) mysql> select now(); +---------------------+ | now() | +---------------------+ | 2010-12-30 09:59:29 | +---------------------+ 1 row in set (0.00 sec) Is it possible to put that in an option file e.g. .my

Changes I make to my.cnf don't seem to have any effect on the mysql environment. Here's a summary of what's happened... I installed mysql 5.7 on Ubuntu 16.04 but then realized I needed to downgrade to mysql 5.6 due to incompatibility issues. I apt purged the related applications and then removed any remaining directories such at /etc/mysql and /var/lib/mysql I then installed mysql-5.6 (server and client) and related packages. I was able to load one database from a dump from a server also running mysql 5.6 but when I tried to load a second database from a second dump from that same server, I

I used mysqldump to export my database and then I imported it into MySQL on my other server. I can now see all my tables if I do "show tables" but I can't actually select from or describe any of them. ERROR 1146 (42S02): Table 'mydatabase.user' doesn't exist All of my tables are InnoDB. I saw one issue people had where they were using old_passwords, so I explicitly set that to 0 in my.cnf and I made sure all of the passwords in the mysql table were 41 hexadecimal digits as they should be for the new passwords. RolandoMySQLDBA The reason "show tables;" works is because mysqld will scan the

I am kind of hoping that someone might be able to offer some assistance with optimizing a my.cnf file for an extremely high volume mysql database server. Our architecture is as follows: Memory : 96GB CPUs : 12 OS & Mysql : 64-bit Disk Space : 1.2 TB DB Engine : MyISAM Our web application is used by roughly 300 client simultaneously. We need our my.cnf tuned to give the best possible performance for this infrastructure. I am fully aware that indexes and optimized queries are a major factor in this, but we would like to start with a system that is configured properly and then follow that up with
