The RedHat system can be found on the Internet. There is no article about the MySQL cluster of the Ubuntu system.
I am writing the Ubuntu MySQL cluster method. Don't scold me for being a newbie.
Introduction to the network environment:
Test environment:
Server1: ndbd 192.168.245.11
Server2: ndbd 192.168.245.12
Server3: mysqld-ndb-cluster 192.168.245.13
Ndbd: Database node.
Mysqld-ndb-cluster: MySQL server node. The IP address of this machine is directly accessed by the program. The default port number is 3306.
Ndbd_mgm ndbd_mgmd: Management node. Manage/view the status of each database node and server node.
Ii. Cluster Solution
1. Management node: server3 (192.168.245.13)
2. storage nodes: server1 (192.168.245.11), server2 (192.168.245.12)
3. SQL nodes: server1 (192.168.245.11), server2 (192.168.245.12), and server3 (192.168.245.13)
Iii. mysql installation and configuration
1. install sudo apt-get install mysql-server
2. Configure my. cnf on the three servers.
Vim/etc/mysql/my. cnf
-------------- My. cnf start ---------------
Ubuntu @ ubuntu :~ $ Cat/etc/mysql/my. cnf
#
# The MySQL database server configuration file.
#
# You can copy this to one:
#-"/Etc/mysql/my. cnf" to set global options,
#-"~ /. My. cnf "to set user-specific options.
#
# One can use all long options that the program supports.
# Run program with-help to get a list of available options and
#-Print-defaults to see which it wocould actually understand use.
#
# For explanations see
#... Ables.html
# This will be passed to all mysql clients
# It has been reported that passwords shoshould be enclosed with ticks/quotes
# Escpecially if they contain "#" chars...
# Remember to edit/etc/mysql/debian. cnf when changing the socket location.

# If you make changes to these settings and your system uses apparmor, you may
# Also need to also adjust/etc/apparmor. d/usr. sbin. mysqld.

# * BerkeleyDB
#
# Using BerkeleyDB is now discouraged as its support will cease in 5.1.12.

#
# * MyISAM
#
# MyISAM is enabled by default with a 10 MB datafile in/var/lib/mysql /.
# Read the manual for more MyISAM related options. There are unavailable!
# You might want to disable MyISAM to shrink the mysqld process by circa 100 MB.
# Skip-innodb
#
# * Security Features
#
# Read the manual, too, if you want chroot!
# Chroot =/var/lib/mysql/
#
# For generating SSL certificates I recommend the OpenSSL GUI "tinyca ".
#
# Ssl-ca =/etc/mysql/cacert. pem

# Not from the NDB Management Nodes (ndb_mgmd processes ).
#

----------- My. cnf ended -------------------
Add the following content under [mysqld:
Ndbcluster
Ndb-connectstring = 192.168.245.13
And add
[MYSQL_CLUSTER]
Ndb-connectstring = 192.168.245.13
The three servers above must be the same.
