Heartbeat 3.0.4-drbd 8.9-Mysql 5.6 Mel-dual standby high availability deployment

2025-04-28 Update From: SLTechnology News&Howtos shulou NAV: SLTechnology News&Howtos > Database >

Shulou(Shulou.com)06/01 Report--

Heartbeat 3.0.4-drbd 8.9-MySQL 5.6Synergy: first of all, heartbeat, as a highly available control role, is responsible for mounting the drbd storage service directory. (here, the startup of drbd is automatically started with the host.

Started, its function is to synchronize a local disk of the primary node with a disk of the standby node at the opposite end, and to ensure that the data in the data disk related to the host drbd on both sides are completely the same), and the storage directory of drbd is only mounted and read on the master node.

Write, while the standby remains unavailable; when heartbeat finishes mounting the drbd storage directory, start the mysql database, and heartbeat is responsible for checking the status of drbd storage and mysql service. When the service is abnormal, the resource is transferred through the timeout mechanism.

Start in the standby machine, so as to achieve the purpose of high availability of mutual backup between mysql computers.

Prerequisites:

Complete the installation and configuration of linux-ha heartbeat according to the blog post on the highly available installation configuration of heartbeat (http service is highly available)

Follow the blog post MySQL 5.6 for REHL 6.4 to compile and install mysql to complete the installation and configuration.

To start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER! To do so, start the server, then issue the following commands:

/ application/mysql/bin/mysqladmin-u root password' new-password' / application/mysql/bin/mysqladmin-u root-h 192.168.144.132 password' new-password'

Alternatively you can run:

/ application/mysql/bin/mysql_secure_installation

Which will also give you the option of removing the test databases and anonymous user created by default. This is strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

Cd. ; / application/mysql/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

Cd mysql-test; perl mysql-test-run.pl

WARNING: Found existing config file / application/mysql/my.cnf on the system. Because this file might be in use, it was not replaced, but was used in bootstrap (unless you used-- defaults-file) and when you later start the server.

WARNING: Default config file / etc/my.cnf exists on the system This file will be read by default by the MySQL server If you do not want to use this, either remove it, or use the-- defaults-file argument to mysqld_safe when starting the server [root@mymongo1 scripts] #
