That also means that one can load any function from any library, for example exit() from libc.so -a, --ansi Use ANSI SQL syntax instead of MySQL syntax. This mode will also set transaction isolation level 'serializable'. --auto-increment-increment[=#] Auto-increment columns are incremented by this --auto-increment-offset[=#] Offset added to Auto-increment columns.

'mixed' is statement-based binary logging except for those statements where only row-based is correct: those which involve user-defined functions (i.e. UDFs) or the UUID() function; for those, row-based binary logging is automatically used. --bootstrap Used by mysql installation scripts. --bulk_insert_buffer_size=# Size of tree cache used in bulk insert optimisation.

To specify more than one table to ignore, use the directive multiple times, once for each table. This will work for cross-database updates. Example: replicate-wild-ignore-table=foo%.bar% will not do updates to tables in databases that start with foo and whose table names start with bar. --report-host=name Hostname or IP of the slave to be reported to to the master during slave registration. Will appear in the output of SHOW SLAVE HOSTS. Leave unset if you do not want the slave to register itself with the master. Note that it is not sufficient for the master to simply read the IP of the slave off the socket once the slave connects.

In STRICT mode, replication will stop on any unexpected difference between the master and the slave. --slave-load-tmpdir=name The location where the slave should put its temporary files when replicating a LOAD DATA INFILE command. --slave-skip-errors=name Tells the slave thread to continue replication when a query event returns an error from the provided list. --slave_compressed_protocol Use compression on master/slave protocol. --slave_net_timeout=# Number of seconds to wait for more data from a master/slave connection before aborting the read. --slave_transaction_retries=# Number of times the slave SQL thread will retry a transaction in case it failed with a deadlock or elapsed lock wait timeout, before giving up and stopping. --slow-query-log Enable|disable slow query log --slow_launch_time=# If creating the thread takes longer than this value (in seconds), the Slow_launch_threads counter will be incremented. --slow_query_log_file=name Log slow queries to given log file. Defaults logging to hostname-slow.log. Must be enabled to activate other slow log options. --socket=name Socket file to use for connection. --sort_buffer_size=# Each thread that needs to do a sort allocates a buffer of this size. --sporadic-binlog-dump-fail Option used by mysql-test for debugging and testing of replication. --sql-bin-update-same=# The update log is deprecated since version 5.0, is replaced by the binary log and this option does nothing anymore. --sql-mode=name Syntax: sql-mode=option[,option[,option...]] where option can be one of: REAL_AS_FLOAT, PIPES_AS_CONCAT, ANSI_QUOTES, IGNORE_SPACE, ONLY_FULL_GROUP_BY, NO_UNSIGNED_SUBTRACTION. --ssl Enable SSL for connection (automatically enabled with other flags). Disable with --skip-ssl. --ssl-ca=name CA file in PEM format (check OpenSSL docs, implies --ssl). --ssl-capath=name CA directory (check OpenSSL docs, implies --ssl). --ssl-cert=name X509 cert in PEM format (implies --ssl). --ssl-cipher=name SSL cipher to use (implies --ssl). --ssl-key=name X509 key in PEM format (implies --ssl). --standalone Dummy option to start as a standalone program (NT). -s, --symbolic-links Enable symbolic link support. --sync-binlog=# Synchronously flush binary log to disk after every #th event. Use 0 (default) to disable synchronous flushing. --sync-frm Sync .frm to disk on create. Enabled by default. --sysdate-is-now Non-default option to alias SYSDATE() to NOW() to make it safe-replicable. Since 5.0, SYSDATE() returns a `dynamic' value different for different invocations, even within the same statement. --table_cache=# Deprecated; use --table_open_cache instead. --table_definition_cache=# The number of cached table definitions. --table_lock_wait_timeout=# Timeout in seconds to wait for a table level lock before returning an error. Used only if the connection has active cursors. --table_open_cache=# The number of cached open tables. --tc-heuristic-recover=name Decision to use in heuristic recover process. Possible values are COMMIT or ROLLBACK. --temp-pool This option is ignored on this OS. --thread_cache_size=# How many threads we should keep in a cache for reuse. --thread_concurrency=# Permits the application to give the threads system a hint for the desired number of threads that should be run at the same time. --thread_handling=name Define threads usage for handling queries: one-thread-per-connection or no-threads --thread_stack=# The stack size for each thread. --timed_mutexes Specify whether to time mutexes (only InnoDB mutexes are currently supported) --time_format=name The TIME format (for future). -t, --tmpdir=name Path for temporary files. Several paths may be specified, separated by a semicolon (;), in this case they are used in a round-robin fashion. --tmp_table_size=# If an internal in-memory temporary table exceeds this size, MySQL will automatically convert it to an on-disk MyISAM table. --transaction-isolation=name Default transaction isolation level. --transaction_alloc_block_size=# Allocation block size for transactions to be stored in binary log --transaction_prealloc_size=# Persistent buffer for transactions to be stored in binary log --updatable_views_with_limit=# 1 = YES = Don't issue an error message (warning only) if a VIEW without presence of a key of the underlying table is used in queries with a LIMIT clause for updating. 0 = NO = Prohibit update of a VIEW, which does not contain a key of the underlying table and the query uses a LIMIT clause (usually get from GUI tools). -s, --use-symbolic-links Enable symbolic link support. Deprecated option; use --symbolic-links instead. -u, --user=name Run mysqld daemon as user. -v, --verbose Used with --help option for detailed help -V, --version Output version information and exit. --wait_timeout=# The number of seconds the server waits for activity on a connection before closing it. -W, --warnings[=#] Deprecated; use --log-warnings instead.
