NAME

6       mysqld - the MySQL server
7

SYNOPSIS

9       mysqld [options]
10

DESCRIPTION

12       mysqld, also known as MySQL Server, is a single multithreaded program
13       that does most of the work in a MySQL installation. It does not spawn
14       additional processes. MySQL Server manages access to the MySQL data
15       directory that contains databases and tables. The data directory is
16       also the default location for other information such as log files and
17       status files.
18
19           Note
20           Some installation packages contain a debugging version of the
21           server named mysqld-debug. Invoke this version instead of mysqld
22           for debugging support, memory allocation checking, and trace file
23           support (see Section 5.9.1.2, “Creating Trace Files”).
24
25       When MySQL server starts, it listens for network connections from
26       client programs and manages access to databases on behalf of those
27       clients.
28
29       The mysqld program has many options that can be specified at startup.
30       For a complete list of options, run this command:
31
32           mysqld --verbose --help
33
34       MySQL Server also has a set of system variables that affect its
35       operation as it runs. System variables can be set at server startup,
36       and many of them can be changed at runtime to effect dynamic server
37       reconfiguration. MySQL Server also has a set of status variables that
38       provide information about its operation. You can monitor these status
39       variables to access runtime performance characteristics.
40
41       For a full description of MySQL Server command options, system
42       variables, and status variables, see Section 5.1, “The MySQL Server”.
43       For information about installing MySQL and setting up the initial
44       configuration, see Chapter 2, Installing and Upgrading MySQL.
