======================主從配置============================
【master1】
====主數據庫設置====
vim /etc/my.cnf
在mysqld中追加

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 status\G

show processlist \G;
【slave】
===從數據庫設置====

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
===設置備份點===
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';

show slave status\G
==================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.雙master服務器網卡設置
使用網線直接連接兩個master，並且配置兩個服務器的IP
2.安裝HA與HA依賴包
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
==配置心跳的監控：haresources==
vim /etc/ha.d/haresources
追加
PL100 IPaddr::192.168.10.245 ipvsadm mysqld
#PL100 爲主主機名（可以使用uname -n獲得） ipvsadm mysqld爲啓動心跳同時啓動該服務。
#IPaddr:: 爲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的日誌文件記錄位置
logfile /var/log/ha_log/ha-log.log
#使用eth3做心跳監測
bcast eth3
#設定心跳(監測)時間時間爲2秒
keepalive 2
warntime 10
deadtime 30
initdead 120
hopfudge 1
#使用udp端口694進行心跳監測
udpport 694
auto_failback on
#節點1，必須要與 uname -n 指令得到的結果一致。
node PL100
#節點2
node PL102
ping 192.168.10.1 #通過ping網關來監測心跳是否正常
#respawn hacluster /usr/lib/heartbeat/ipfail
#apiauth ipfail gid=root uid=root
debugfile /var/log/ha_log/ha-debug.log
#創建日誌文件
touch /var/log/ha_log/ha-log.log
==設置ipvsadm的巡迴監測==
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
執行後則開始進行監測
ipvsadm --list
service heartbeat start
chkconfig --add heartbeat
==防火牆設置==
iptables -I INPUT -p udp --dport 694 -j ACCEPT
