NAME

6       mysqld - the MySQL server
7

SYNOPSIS

9       mysqld [options]
10

DESCRIPTION

12       mysqld, also known as MySQL Server, is the main program that does most
13       of the work in a MySQL installation. MySQL Server manages access to the
14       MySQL data directory that contains databases and tables. The data
15       directory is also the default location for other information such as
16       log files and status files.
17
18           Note
19           Some installation packages contain a debugging version of the
20           server named mysqld-debug. Invoke this version instead of mysqld
21           for debugging support, memory allocation checking, and trace file
22           support (see Section 29.5.1.2, “Creating Trace Files”).
23
24       When MySQL server starts, it listens for network connections from
25       client programs and manages access to databases on behalf of those
26       clients.
27
28       The mysqld program has many options that can be specified at startup.
29       For a complete list of options, run this command:
30
31           shell> mysqld --verbose --help
32
33       MySQL Server also has a set of system variables that affect its
34       operation as it runs. System variables can be set at server startup,
35       and many of them can be changed at runtime to effect dynamic server
36       reconfiguration. MySQL Server also has a set of status variables that
37       provide information about its operation. You can monitor these status
38       variables to access runtime performance characteristics.
39
40       For a full description of MySQL Server command options, system
41       variables, and status variables, see Section 5.1, “The MySQL Server”.
42       For information about installing MySQL and setting up the initial
43       configuration, see Chapter 2, Installing and Upgrading MySQL.
