ruby on rails - Unable to start Mongrel (or Passenger) on Debian due to mysql2 or mysql gems -

-

i posted @ super user, think should here instead...

i'm trying port ror webapp on dreamhost vps. i've upgraded vps --> ruby 1.9.2 1.8.7 , using rails 3.0.1 , mysql2 (0.2.6) gem. i'm getting following error when trying start mongrel:

/usr/bin/ruby1.8: symbol lookup error: /home/username/.gems/gems/mysql2-0.2.6/lib/mysql2/mysql2.so: undefined symbol: rb_intern2

...so tried using mysql (2.8.1) gem instead , following error:

wrong argument type mysql (expected struct) (typeerror)

i'd prefer use mysql2, that's preferred solution i'm looking for, appreciate input on either problem.

i'm not encountering problems such in development environment (which windows)

you'd mentioned you're running ruby 1.9.2 error dump looks it's running ruby 1.8 i'm not sure cause problem or not seems potential issue.

i'd uninstall ruby1.8 , see if fixes anything.

sudo apt-get remove ruby1.8

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
