本文档详细介绍了 MySQL Cluster 的配置过程，包括不同配置文件（如 my.cnf 和 config.ini）的具体设置，涵盖数据节点、管理节点及 SQL 节点的各项参数。适合希望深入了解 MySQL Cluster 架构与配置细节的技术人员。

自己经历的mysql cluter配置过程

76.my.cnf

#mple MySQL config file for medium systems.

# This is for a system with little memory (32M - 64M) where MySQL plays

# an important part , or systems up to 128M where MySQL is used together with

# other programs (such as a web server)

# You can copy this file to

# /etc/my.cnf to set global options ,

# mysql-data-dir/my.cnf to set server-specific options (in this

# installation this directory is /var/lib/mysql) or

# ~/.my.cnf to set user-specific options.

# In this file , you can use all long options that a program supports.

# If you want to know which options a program supports , run the program

# with the " --help " option.

# The following options will be passed to all MySQL clients

[ client ]

#password = your_password

port = 3307

socket = /var/lib/mysql/mysql.sock

# Here follows entries for some specific programs

# The MySQL server

[ mysqld ]

datadir = /var/lib/mysql

user = root

port = 3306

socket = /var/lib/mysql/mysql.sock

skip-locking

key_buffer = 16M

max_allowed_packet = 1M

table_cache = 64

sort_buffer_size = 512K

net_buffer_length = 8K

read_buffer_size = 256K

read_rnd_buffer_size = 512K

myisam_sort_buffer_size = 8M

#datadir = /mysqldata

# Don't listen on a TCP/IP port at all. This can be a security enhancement ,

# if all processes that need to connect to mysqld run on the same host.

# All interaction with mysqld must be made via Unix sockets or named pipes.

# Note that using this option without enabling named pipes on Windows

# (via the " enable-named-pipe " option) will render mysqld useless!

#skip-networking

# Replication Master Server (default)

# binary logging is required for replication

log-bin = mysql-bin

# required unique id between 1 and 2 ^ 32 - 1

# defaults to 1 if master-host is not set

# but will not function as a master if omitted

server-id = 1

# Replication Slave (comment out master section to use this)

# To configure this host as a replication slave , you can choose between

# two methods :

# 1 ) Use the CHANGE MASTER TO command (fully described in our manual) -

# the syntax is:

# CHANGE MASTER TO MASTER_HOST = <host> , MASTER_PORT = <port> ,

# MASTER_USER = <user> , MASTER_PASSWORD = <password> ;

# where you replace <host> , <user> , <password> by quoted strings and

# <port> by the master's port number ( 3306 by default).

# Example:

# CHANGE MASTER TO MASTER_HOST = ' 125.564.12.1 ' , MASTER_PORT = 3306 ,

# MASTER_USER = 'joe' , MASTER_PASSWORD = 'secret' ;

# OR

# 2 ) Set the variables below. However , in case you choose this method , then

# start replication for the first time (even unsuccessfully , for example

# if you mistyped the password in master-password and the slave fails to

# connect) , the slave will create a master.info file , and any later

# change in this file to the variables' values below will be ignored and

# overridden by the content of the master.info file , unless you shutdown

# the slave server , delete master.info and restart the slaver server.

# For that reason , you may want to leave the lines below untouched

# (commented) and instead use CHANGE MASTER TO (see above)

# required unique id between 2 and 2 ^ 32 - 1

# (and different from the master)

# defaults to 2 if master-host is set

# but will not function as a slave if omitted

#server-id = 2

# The replication master for this slave - required

#master-host = <hostname>

# The username the slave will use for authentication when connecting

# to the master - required

#master-user = <username>

# The password the slave will authenticate with when connecting to

# the master - required

#master-password = <password>

# The port the master is listening on.

# optional - defaults to 3306

#master-port = <port>

# binary logging - not required for slaves , but recommended

#log-bin = mysql-bin
