MySQL-MMM deployment architecture

• problem

This case requires familiarity implement MySQL-MMM deployment architecture, including the following tasks:

1. Installation dependencies
2. Installation package
3. Configure MySQL-MMM

• Program

RHEL 6 using five virtual machines shown in Figure -2. Which 192.168.4.10,192.168.4.11 double as the MySQL master server, 192.168.4.12,192.168.4.13 as the primary server from the server, 192.168.4.100 as MySQL-MMM management and monitoring server architecture to achieve master status from monitoring MySQL server and decide to remove the failed node or return to work, architecture uses a client set up after the completion of 192.168.4.120 to access the client need to install MySQL-client packages.

• step

This case needs to be achieved in the following steps.

Step a: install M ySQL-MMM

1) Installation Dependencies (MySQL Cluster within five servers master1, master2, slave1, slave2, monitor) are required to install

[root@master1 ~]# yum -y install gcc* perl-Date-Manip  perl-Date-Manip  perl-Date-Manip perl-XML-DOM-XPath perl-XML-Parser perl-XML-RegExp rrdtool perl-Class-Singleton perl perl-DBD-MySQL perl-Params-Validate perl-MailTools perl-Time-HiRes

.. ..

2) install MySQL-MMM-dependent software package (MySQL Cluster within five servers master1, master2, slave1, slave2, monitor) need to be installed, the package provides lecturers

Installation based Log-Log4perl

[root@mysql-master1 ~]# rpm -ivh perl-Log-Log4perl-1.26-1.el6.rf.noarch.rpm

warning: perl-Log-Log4perl-1.26-1.el6.rf.noarch.rpm: Header V3 DSA/SHA1 Signature, key ID 6b8d79e6: NOKEY

Installation based Algorithm-Diff

[root @ mysql-master1 ~] # tar -zxvf Algorithm-Diff-1.1902.tar.gz // extract the installation package

.. ..

[Master1 the root-MySQL @ ~] Algorithm-Diff-CD # 1.1902 // to the installation directory

[root @ MySQL-Master1 Mathimatics-Numerical algorithms-Diff-1.1902] # perl Makefile.PL // generate the makefile

Checking if your kit is complete...

Looks good

Writing Makefile for Algorithm::Diff

 

[root @ MySQL-Master1 Mathimatics-Numerical algorithms-Diff-1.1902] the make install # the make && // compile, compile and install

.. ..

[root @ MySQL-Master1 Mathimatics-Numerical algorithms-Diff-1.1902] # cd // switch to the package directory

[root@mysql-master1 ~]#

Installation based Proc-Daemon

[Master1 the root-MySQL @ ~] # -zxvf Proc the tar-Daemon-0.03.tar.gz // extract the installation package

.. ..

[Master1 the root-MySQL @ ~] Proc-Daemon-CD # 0.03 // to the installation directory

[root @ Master1 Proc-MySQL-Daemon-0.03] # perl Makefile.PL // generate the makefile

Looks good

Writing Makefile for Proc::Daemon

[root @ Master1 Proc-MySQL-Daemon-0.03] # the make the make install && // compile, compile and install

.. ..

[root @ Master1 Proc-MySQL-Daemon-0.03] # cd // switch to the package directory

[root@mysql-master1 ~]#

Install Net-ARP virtual IP assignment tool:

[Master1 the root-MySQL @ ~] # Net-gunzip the ARP-1.0.8.tgz // use gunzip it tgz format installation package

[Master1 the root-MySQL @ ~] # Net-tar xvf the ARP-1.0.8.tar // tar extract the installation package

.. ..

[Master1 the root-MySQL @ ~] # Net-CD the ARP-1.0.8 // to the installation directory

[root @ Net-MySQL-Master1 ARP-1.0.8] # perl Makefile.PL // generate the makefile

Module Net::Pcap is required for make test!

Checking if your kit is complete...

Looks good

Writing Makefile for Net::ARP

[root @ Net-MySQL-Master1 ARP-1.0.8] # the make the make install && // compile, compile and install

.. ..

[root @ Net-MySQL-Master1 ARP-1.0.8] # cd // switch to the package directory

[root@mysql-master1 ~]#

Mysql-MMM installation package:

[Master1 the root-MySQL @ ~] # MySQL xvf the tar-MMM-2.2.1.tar.gz // extract the installation package

.. ..

[Master1 the root-MySQL @ ~] # CD-MMM-MySQL 2.2.1 // to the installation directory

[root @ Master1 MySQL-MySQL-MMM-2.2.1] # the make the make install && // compile, compile and install

.. ..

[root@mysql-master1 mysql-mmm-2.2.1]#

Step two: modify the configuration file

1) modifying the public profile

In this case five servers MySQL Cluster (master1, master2, slave1, slave2, monitor) will need to be configured, you can use scp to copy with the good one.

[root@master1 ~]# vim  /etc/mysql-mmm/mmm_common.conf

active_master_role writer

 

<host default>

cluster_interface eth0 // master-slave synchronization is provided a user

 

pid_path /var/run/mmm_agentd.pid

bin_path /usr/lib/mysql-mmm/

 

 slaveuser replication_user // set the user's master-slave synchronization

 pwd123 replication_password // master-slave synchronization setting user password

 

agent_user Agent // MMM-User Database Control Agent

agent_password Agent // MMM-Control Agent database user password

</host>

 

<Host Master1> // set the first master

ip 192.168.4.10 // IP address Master1

mode the master

Use the peer Master2 // a designated primary server further

</host>

 

<Host Master2> // Specify another master server

ip 192.168.4.11

mode the master

peer master1

</host>

 

<Host Slave1> // provided from the first server

ip 192.168.4.12 // IP address slave1

MODE slave // this paragraph is configured slave server

</host>

 

<host slave2>

ip 192.168.4.13

mode slave

</host>

 

<Role Writer> // set the write server operating mode

hosts Master1, Master2 // provide written master server

IPS 192.168.4.200 // set the VIP address

the MODE exclusive // exclusive mode

</role>

 

<Role Reader> // set the read mode of operation server

hosts slave1, slave2 // server provides information to read

IPS 192.168.4.201,192.168.4.202 multiple virtual IP //

the MODE Balanced // balanced mode

</role>

[root@master1 ~]#

2) modify the configuration file management host (monitor host configuration)

[root@monitor ~]# vim /etc/mysql-mmm/mmm_mon.conf

include mmm_common.conf

 

<monitor>

ip 192.168.4.100 // set the IP address of the management host

pidpath varrunmmmmondpid

bin_path /usr/lib/mysql-mmm/

status_path /var/lib/misc/mmm_mond.status

ping_ips 192.168.4.10,192.168.4.11,192.168.4.12,192.168.4.13

// set the monitored database

</monitor>

 

<host default>

of monitor_user Monitor // MySQL database monitoring user
monitor_password Monitor // monitor MySQL database user password

</host>

 

debug 0

[root@monitor ~]#

3) Modify the client configuration file

master1 Configuration

[root@master1 ~]# cat /etc/mysql-mmm/mmm_agent.conf

include mmm_common.conf

this master1

master2 Configuration

[root@master2 ~]# cat /etc/mysql-mmm/mmm_agent.conf

include mmm_common.conf

this master2

slave1 Configuration

[root@slave1 ~]# cat /etc/mysql-mmm/mmm_agent.conf

include mmm_common.conf

this slave1

slave2 Configuration

[root@slave2 ~]# cat /etc/mysql-mmm/mmm_agent.conf

include mmm_common.conf

this slave2
