=======================mysql配置=================================

cd /usr/local/mysql-5.5.27/

cp ./support-files/my-huge.cnf /etc/my.cnf

cp ./support-files/mysql.server /etc/rc.d/init.d/mysqld

chmod 700 /etc/rc.d/init.d/mysqld

chkconfig --add mysqld

mkdir -p /data/mysql

mkdir -p /data/mysql/3306/logs/binlog/

chown -R mysql:mysql /data/mysql

/usr/local/mysql-5.5.27/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql-5.5.27 --datadir=/data/mysql/3306/data

service mysqld start

cp -rf /usr/local/mysql-5.5.27/bin/* /usr/bin/

mysqladmin -u root password 'pinla2012'

======================主从配置============================

【master1】

====主数据库设置====

vim /etc/my.cnf

在mysqld中追加

#********master1*********

server-id=1

log-bin=mysql-bin

read-only=0

innodb_flush_log_at_trx_commit=1

sync_binlog=1

#binlog-do-db=pinladb

auto_increment_offset=1

service mysqld restart

mysql -uroot -p

GRANT FILE,REPLICATION SLAVE,REPLICATION CLIENT,SUPER,RELOAD ON *.* TO pl_backup@'%'IDENTIFIED by 'pinla2012';

==pinla_backup账号测试==

mysql -h192.168.10.240 -upinla_backup -p

change master to master_host='192.168.10.245',master_user='pl_backup',master_password='pinla2012', master_log_file='mysql-bin.000005';

flush privileges;

slave start;

show slave statusG

【master2】

#********master2*********

log-bin=mysql-bin

read-only=0

innodb_flush_log_at_trx_commit=1

sync_binlog=1

#binlog-do-db=pinladb

GRANT FILE,REPLICATION SLAVE,REPLICATION CLIENT,SUPER,RELOAD ON *.* TO pl_backup@'%'IDENTIFIED by 'pinla2012';

==pinla_backup账号测试==

mysql -h192.168.10.245 -upinla_backup -p

change master to master_host='192.168.10.240',master_user='pl_backup',master_password='pinla2012', master_log_file='mysql-bin.000008';

flush privileges;

slave start;

show slave statusG

show processlist G;

【slave】

===从数据库设置====

#****slave******

server-id=10

log-bin=mysql-bin

binlog_format=mixed

replicate-ignore-db=test

replicate-ignore-db=mysql

replicate-ignore-db=information_schema

relay-log=db-server-2-relay-bin

log-slave-updates

===设置备份点===

mysql -uroot -p

slave stop;

change master to master_host='192.168.10.240',master_user='pl_backup',master_password='pinla2012', master_log_file='mysql-bin.000008';

slave start;

show slave statusG

==================heartbeat配置===========================

vip：192.168.10.244

master1-eth3:192.168.10.240

master1-eth2:10.10.10.100

master2-eth0:10.10.10.200

master2-eth1:192.168.10.245

1.双master服务器网卡设置

使用网线直接连接两个master，并且配置两个服务器的IP

2.安装HA与HA依赖包

yum install libnet heartbeat* heartbeat-devel heartbeat-pils heartbeat-stonith heartbeat-ldirectord ipvsadm

cp /usr/share/doc/heartbeat-2.1.3/authkeys /etc/ha.d/

cp /usr/share/doc/heartbeat-2.1.3/haresources /etc/ha.d/

cp /usr/share/doc/heartbeat-2.1.3/ha.cf /etc/ha.d/

==配置心跳加密方式:authkeys==

vim /etc/ha.d/authkeys

auth 1

1 crc

chmod 600 /etc/ha.d/authkeys

==配置心跳的监控：haresources==

vim /etc/ha.d/haresources

追加

PL100 IPaddr::192.168.10.245 ipvsadm mysqld

#PL100 为主主机名(可以使用uname -n获得) ipvsadm mysqld为启动心跳同时启动该服务。

#IPaddr:: 为VIP

mkdir -p /var/log/ha_log

chmod 777 /var/log/ha_log

==配置心跳的配置文件：ha.cf==

vi /etc/ha.d/ha.cf

#ha的日志文件记录位置

logfile /var/log/ha_log/ha-log.log

#使用eth3做心跳监测

bcast eth3

#设定心跳(监测)时间时间为2秒

keepalive 2

warntime 10

deadtime 30

initdead 120

hopfudge 1

#使用udp端口694进行心跳监测

udpport 694

auto_failback on

#节点1，必须要与 uname -n 指令得到的结果一致。

node PL100

#节点2

node PL102

ping 192.168.10.1 #通过ping网关来监测心跳是否正常

#respawn hacluster /usr/lib/heartbeat/ipfail

#apiauth ipfail gid=root uid=root

debugfile /var/log/ha_log/ha-debug.log

#创建日志文件

touch /var/log/ha_log/ha-log.log

==设置ipvsadm的巡回监测==

ipvsadm -A -t 192.168.10.244:3306 -s rr

ipvsadm -a -t 192.168.10.244:3306 -r 10.10.10.100:3306 -m

ipvsadm -a -t 192.168.10.244:3306 -r 10.10.10.200:3306 -m

执行后则开始进行监测

ipvsadm --list

service heartbeat start

chkconfig --add heartbeat

==防火墙设置==

iptables -I INPUT -p udp --dport 694 -j ACCEPT
