Compiled HTML/TXT check-in. For some reason, it keeps thinking my darn

It gets<br> +asked a lot, and the only option current listed in the FAQ is<br> +"--skip-grant-tables".<br> +<br> +Really, you can't go wrong by reading section 6 of the MySQL manual, at<br> +http://www.mysql.com/Manual/manual.html. I am sure their description is<br> +better than mine.<br> +<br> +MySQL runs fine without permissions set up correctly if you run the mysql<br> +daemon with the "--skip-grant-tables" option. Running this way denies<br> +access to nobody. Unfortunately, unless you've got yourself firewalled it<br> +also opens the potential for abuse if someone knows you're running it.<br> +<br> +Additionally, the default permissions for MySQL allow anyone at localhost<br> +access to the database if the database name begins with "test_" or is named<br> +"test" (i.e. "test_keystone"). You can change the name of your database in<br> +the keystone.conf file ($sys_dbname). This is the way I am doing it for<br> +some of my databases, and it works fine.<br> +<br> +The methods described below assume you're running MySQL on the same box as<br> +your webserver, and that you don't mind if your $sys_dbuser for Keystone has<br> +superuser access. See near the bottom of this message for a description of<br> +what each field does.<br> +<br> +Method #1:<br> +<br> +1. cd /var/lib<br> + #location where you'll want to run /usr/bin/mysql_install_db shell<br> +script from to get it to work.<br> +<br> +2. ln -s mysql data <br> + # soft links the "mysql" directory to "data", which is what<br> +mysql_install_db expects. Alternately, you can edit mysql_install_db and<br> +change all the "./data" references to "./mysql".<br> +<br> +3. Edit /usr/bin/mysql_install_db with your favorite text editor (vi,<br> +emacs, jot, pico, etc.)<br> +A) Copy the "INSERT INTO db VALUES<br> +('%','test\_%','','Y','Y','Y','Y','Y','Y');" and paste it immediately after<br> +itself. Chage the 'test\_%' value to 'keystone', or the value of<br> +$sys_dbname in keystone.conf.<br> +B) If you are running your keystone database with any user, you'll need to<br> +copy the "INSERT INTO user VALUES<br> +('localhost','root','','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y');" line after<br> +itself and change 'root' to the name of the keystone database user<br> +($sys_dbuser) in keystone.conf.<br> +<br> + # adds entries to the script to create grant tables for specific<br> +hosts and users. The user you set up has super-user access ($sys_dbuser) --<br> +you may or may not want this. The layout of mysql_install_db is really very<br> +uncomplicated.<br> +<br> +4. /usr/bin/mysqladmin shutdown<br> + # ya gotta shut it down before you can reinstall the grant tables!<br> +<br> +5. rm -i /var/lib/mysql/mysql/*.IS?' and answer 'Y' to the deletion<br> +questions.<br> + # nuke your current grant tables. This WILL NOT delete any other<br> +databases than your grant tables.<br> +<br> +6. /usr/bin/mysql_install_db<br> + # run the script you just edited to install your new grant tables.<br> +<br> +7. mysqladmin -u root password (new_password) <br> + # change the root MySQL password, or else anyone on localhost can<br> +login to MySQL as root and make changes. You can skip this step if you want<br> +keystone to connect as root with no password.<br> +<br> +8. mysqladmin -u (webserver_user_name) password (new_password) <br> + # change the password of the $sys_dbuser. Note that you will need<br> +to change the password in the keystone.conf file as well in $sys_dbpasswd,<br> +and if your permissions are set up incorrectly anybody can type the URL to<br> +your keystone.conf file and get the password. Not that this will help them<br> +much if your permissions are set to @localhost.<br> +<br> +<br> +<br> +Method #2: easier, but a pain reproducing if you have to delete your grant<br> +tables. This is the "recommended" method for altering grant tables in<br> +MySQL. I don't use it because I like the other way :)<br> +<br> +shell> mysql --user=root keystone<br> +<br> +mysql> GRANT<br> +SELECT,INSERT,UPDATE,DELETE,INDEX,ALTER,CREATE,DROP,RELOAD,SHUTDOWN,PROCESS,<br> +FILE,<br> + ON keystone.*<br> + TO <$sys_dbuser name>@localhost<br> + IDENTIFIED BY '(password)'<br> + WITH GRANT OPTION;<br> +<br> +OR<br> +<br> +mysql> GRANT ALL PRIVELEGES <br> + ON keystone.*<br> + TO <$sys_dbuser name>@localhost<br> + IDENTIFIED BY '(password)'<br> + WITH GRANT OPTION;<br> +<br> + # this grants the required permissions to the keystone ($sys_dbuser)<br> +account defined in keystone.conf. However, if you are runnning many<br> +different MySQL-based apps, as we are, it's generally better to edit the<br> +mysql_install_db script to be able to quickly reproduce your permissions<br> +structure again. Note that the FILE privelege and WITH GRANT OPTION may not<br> +be in your best interest to include.<br> +<br> +<br> +GRANT TABLE FIELDS EXPLANATION:<br> +Quick syntax summary: "%" in MySQL is a wildcard. I.E., if you are<br> +defining your DB table and in the 'host' field and enter '%', that means<br> +that any host can access that database. Of course, that host must also have<br> +a valid db user in order to do anything useful. 'db'=name of database. In<br> +our case, it should be "keystone". "user" should be your "$sys_dbuser"<br> +defined in keystone.conf. Note that you CANNOT add or change a password by<br> +using the "INSERT INTO db (X)" command -- you must change it with the mysql<br> +-u command as defined above. Passwords are stored encrypted in the MySQL<br> +database, and if you try to enter it directly into the table they will not<br> +match.<br> +<br> +TABLE: USER. Everything after "password" is a privelege granted (Y/N).<br> +This table controls individual user global access rights.<br> +<br> +'host','user','password','select','insert','update','delete','index','alter'<br> +,'create','drop','grant','reload','shutdown','process','file'<br> +<br> +TABLE: DB. This controls access of USERS to databases.<br> +<br> +'host','db','user','select','insert','update','delete','index','alter','crea<br> +te','drop','grant'<br> +<br> +TABLE: HOST. This controls which HOSTS are allowed what global access<br> +rights. Note that the HOST table, USER table, and DB table are very closely<br> +connected -- if an authorized USER attempts an SQL request from an<br> +unauthorized HOST, she's denied. If a request from an authorized HOST is<br> +not an authorized USER, it is denied. If a globally authorized USER does<br> +not have rights to a certain DB, she's denied. Get the picture?<br> +<br> +'host','db','select','insert','update','delete','index','alter','create','dr<br> +op','grant'<br> +<br> +<br> +You should now have a working knowledge of MySQL grant tables. If there is<br> +anything I've left out of this answer that you feel is pertinent, or if my<br> +instructions don't work for you, please let me know and I'll re-post this<br> +letter again, corrected. I threw it together one night out of exasperation<br> +for all the newbies who don't know squat about MySQL yet, so it is almost<br> +guaranteed to have errors.<br> +<br> +Once again, you can't go wrong by reading section 6 of the MySQL manual.
