mysqld_multi

A server startup script that can start or stop multiple servers installed on the system. See Section 4.3.4, “mysqld_multi — Manage Multiple MySQL Servers”.

comp_err

This program is used during the MySQL build/installation process. It compiles error message files from the error source files. See Section 4.4.1, “comp_err — Compile MySQL Error Message File”.

This program enables you to improve the security of your MySQL installation. See Section 4.4.2, “mysql_secure_installation — Improve MySQL Installation Security”.

mysql_ssl_rsa_setup

This program creates the SSL certificate and key files and RSA key-pair files required to support secure connections, if those files are missing. Files created by mysql_ssl_rsa_setup can be used for secure connections using SSL or RSA. See Section 4.4.3, “mysql_ssl_rsa_setup — Create SSL/RSA Files”.

mysql_tzinfo_to_sql

This program loads the time zone tables in the mysql database using the contents of the host system zoneinfo database (the set of files describing time zones). See Section 4.4.4, “mysql_tzinfo_to_sql — Load the Time Zone Tables”.

X DevAPI enables you to work with both relational and document data, see Chapter 20, Using MySQL as a Document Store. AdminAPI enables you to work with InnoDB cluster, see Chapter 21, InnoDB Cluster.

mysqlshow

A client that displays information about databases, tables, columns, and indexes. See Section 4.5.7, “mysqlshow — Display Database, Table, and Column Information”.

mysqlslap

A client that is designed to emulate client load for a MySQL server and report the timing of each stage. It works as if multiple clients are accessing the server. See Section 4.5.8, “mysqlslap — Load Emulation Client”.

innochecksum

An offline InnoDB offline file checksum utility. See Section 4.6.2, “innochecksum — Offline InnoDB File Checksum Utility”.
