1 install mysql

请参考https://www.512pic.com/article/47094.htm

2. Basic configuration of master 1

3. Create usersGRANT REPLICATION CLIENT ON *.* TO 'mmm_monitor'@'%' IDENTIFIED BY 'mmm_monitor';GRANT SUPER, REPLICATION CLIENT, PROCESS ON *.* TO 'mmm_agent'@'%' IDENTIFIED BY 'mmm_agent';GRANT REPLICATION SLAVE ON *.* TO 'repl'@'10.88.49.%' IDENTIFIED BY 'repl';grant insert,create,delete,update,select on *.* to 'tim'@'%' identified by 'tim';Note: Don not use a replication_password longer than 32 characters

4. Synchronisation of data between both databases

5. Setup replicationset m-s:change master to master_host='10.88.49.119',master_log_file='mysql56-bin.000026',master_log_pos=332, master_user='repl',master_password='repl';

6. Install mmm6.1 download mmm.tar.gzwget http://mysql-mmm.org/_media/:mmm2:mysql-mmm-2.2.1.tar.gz6.2 mv :mmm2:mysql-mmm-2.2.1.tar.gz mysql-mmm-2.2.1.tar.gztar -xvf mysql-mmm-2.2.1.tar.gzcd mysql-mmm-2.2.1makecmake[] don not require make and make install, there have *.conf in /etc/mysql-mmm folder.

7. install lib packageyum install -y perl-*yum install -y libart_lgpl.x86_64yum install -y mysql-mmm.noarch failyum install -y rrdtool.x86_64yum install -y rrdtool-perl.x86_647.1 []another way to install lib package in networkcpan -i Algorithm::Diff Class::Singleton DBI DBD::mysql Log::Dispatch Log::Log4perl Mail::Send Net::Ping Proc::Daemon Time::HiRes Params::Validate Net::ARP

8. Config MMM of DB hostvim /etc/mysql-mmm/mmm_common.confDon not forget to copy this file to all other hosts (including the monitoring host).#Bugsfor$scp /etc/mysql-mmm/mmm_common.conf 10.88.49.119:/etc/mysql-mmm/scp /etc/mysql-mmm/mmm_common.conf 10.88.49.122:/etc/mysql-mmm/scp /etc/mysql-mmm/mmm_common.conf 10.88.49.123:/etc/mysql-mmm/

On the database hosts we need to edit /etc/mysql-mmm/mmm_agent.conf. Change “db1” accordingly on the other hosts:chkconfig --add mysql-mmm-agent

9. Config MonitorOn the monitor host(10.88.49.123) we need to edit /etc/mysql-mmm/mmm_mon.conf:include mmm_common.conf<monitor>ip 127.0.0.1pid_path /var/run/mmm_mond.pidbin_path /usr/lib/mysql-mmm/status_path /var/lib/misc/mmm_mond.statusauto_set_online 5ping_ips 10.88.49.254,10.88.49.130,10.88.49.131,10.88.49.132,10.88.49.133,10.88.49.134</monitor><host default>monitor_user mmm_monitormonitor_password mmm_monitor</host>debug 0ping_ips are some ips that are pinged to determine whether the network connection of the monitor is ok.
