Hello mysql-list,
I try to install MySQL under Cygwin : I can build (mysql-5.5.17 on windows 7
using Cygwin), I can start and stop the server (only using mysqld.server -
mysqladmin fails to connect).
I can not connect to the server when I want to use a password (if I don't use
any password the connection to the server succeeds).
I need client AND server. I followed the on line mysql doc. Some comments about
the installation / running process that I would underline :I do NOT use
--without-server option in configure (I need the server)I use readline (ccmake
configuration) and not libedit : could this be a problem ?I used
mysql_install_db with --basedir, --datadir and --skip-name-resolve optionsI use
a user "dummy" (that belongs to the mysql group) : I can not create the mysql
user (Windows prevent me from creating a mysql user for a reason I can't figure
out : I stopped fighting with Windows. As mentionned in the on-line doc, MySQL
should work with any user : "dummy" is my user - "dummy" belongs to the group
"mysql" - and the password is "dummy")the root user doesn't exist in Cygwin (as
far as I understand) : I can't use any "mysqlamdin -u root ..." as described in
the on-line mysql doc
When I use "mysql" or "mysqladmin" triggering a connection using a password,
the connection fails (but succeeds if no password is used). May be someone
could find a clue to solve this problem !... Could someone help me ?
Thanks
Franck
