E.g. if the "hostname" command returns "myhostname" -then there must be a line like "10.0.0.1 myhostname". - -On upgrades from MySQL 3.23, as shipped with Debian Woody, symlinks in place of -/var/lib/mysql or /var/log/mysql gets accidently removed and have manually be -restored. - -* MYSQL WON'T START OR STOP? -============================ -You may never ever delete the special mysql user "debian-sys-maint". This -user together with the credentials in /etc/mysql/debian.cnf are used by the -init scripts to stop the server as they would require knowledge of the mysql -root users password else. -So in most of the times you can fix the situation by making sure that the -debian.cnf file contains the right password, e.g. by setting a new one -(remember to do a "flush privileges" then). - -* WHAT TO DO AFTER UPGRADES: -============================ - - running mysql_upgrade to be able to make use of possibly added new - privilege columns. This script does not give any use more rights. - -* WHAT TO DO AFTER INSTALLATION: -================================ -The MySQL manual describes certain steps to do at this stage in a separate -chapter. They are not necessary as the Debian packages does them -automatically. - -The only thing that is left over for the admin is - - setting the *passwords* !!! - - creating new users and databases - - read the rest of this text - -* DOWNGRADING TO 4.0 or 4.1: -============================ -Unsupported. Period. -But if you do and get problems or make interesting experiences, mail me, it -might help others. -Ok, if you really want, I would recommend to "mysqldump --opt" all tables, -then purge 4.1, delete /var/lib/mysql, install 4.0 and insert the dumps. Be -carefully, though, with the "mysql" table, you might not simply overwrite that -one as the password for the mysql "debian-sys-maint" user is stored in -/etc/mysql/debian.cnf and needed by /etc/init.d/ to start mysql and check if -it's alive. - -* SOME APPLICATION CAN NO LONGER CONNECT: -========================================= -This application is probably linked against libmysqlclient12 or below and -somebody has created a mysql user with new-style passwords. -The old_passwords option which forces backwards compatibility, can be set -in /etc/mysql/conf.d/old_passwords.conf. -If that does not help, the password can be set manually, the application that -inserted the user should be changed or the application that tries to connect -should be updated to libmysqlclient14 or -15. -Read http://dev.mysql.com/doc/refman/5.0/en/old-client.html - -* NETWORKING: -============= -For security reasons, the Debian package has enabled networking only on the -loop-back device using "bind-address" in /etc/mysql/my.cnf. Check with -"netstat -tlnp" where it is listening. If your connection is aborted -immediately see if "mysqld: all" or similar is in /etc/hosts.allow and read -hosts_access(5). - -* WHERE IS THE DOCUMENTATION?: -============================== -Unfortunately due to licensing restrictions, debian currently not able -to provide the mysql-doc package in any format. For the most up to date -documentation, please go to http://dev.mysql.com/doc. - -* PASSWORDS: -============ -It is strongly recommended to set a password for the mysql root user (which -is NOT the same as the "normal" root user) with the command: - /usr/bin/mysqladmin -u root password 'enter-your-good-new-password-here' -If you already had a password set add " -p " before "-u" to the line above. - -If you are tired to type the password in every time or want to automate your -scripts you can store it in the file $HOME/.my.cnf. It should be chmod 0600 -(-rw------- username username .my.cnf) to ensure that nobody else can read -it. Every other configuration parameter can be stored there, too. You will -find an example below and more information in the MySQL manual in -/usr/share/doc/mysql-doc or www.mysql.com. - -ATTENTION: It is necessary, that a .my.cnf from root always contains a "user" -line wherever there is a "password" line, else, the Debian maintenance -scripts, that use /etc/mysql/debian.cnf, will use the username -"debian-sys-maint" but the password that is in root's .my.cnf. Also note, -that every change you make in the /root/.my.cnf will affect the mysql cron -script, too. - - # an example of $HOME/.my.cnf - [client] - user = your-mysql-username - password = enter-your-good-new-password-here - -* BIG_ROWS FOR EVEN MORE ROWS IN A TABLE: -========================================= -If you ever run out of rows in a table there is the possibility of building -the package with "-DBIG_ROWS" which, according to a MySQL employee on -packagers@lists.mysql.com should lead to a 64bit row index (I guess > 2^32 -rows) but also to an approx. 5% performance loss. - -* NDB CLUSTER ENGINE: -===================== -NDB is the shared-nothing cluster engine since MySQL-4.1. -This package contains the all three components, the mysql backend, the NDB -Data Node and the NDB Management Node. The init scripts of the cluster -daemons will silently exit unless their configuration is provided: - mysql-ndb: needs "ndb-connectstring" in /etc/mysql/my.cnf - mysql-ndb-mgm: needs /etc/mysql/ndb_mgmd.cnf - -* EXPIRE_LOGS_DAYS AND LOG_BIN: -=============================== -Having expire_logs_days enabled but log-bin not crashes the server. Using both -or none of those options is safe. To prevent this happening during the nightly -log rotation via /etc/logrotate.d/mysql the initscript checks for malicious -combination of options. This is Debian bug #368547 and MySQL bug #17733. |
