I due server hanno due NIC:
Chiamiamo il nome host di ogni server www1 o www2 il dominio invece è instyle.locale
(1) www1.instyle.locale[eth0:192.168.100.21] [eth1:10.0.100.21]
(2) www2.instyle.locale[eth0:192.168.100.22] [eth1:10.0.100.22]
(2) www2.instyle.locale[eth0:192.168.100.22] [eth1:10.0.100.22]
yum -y install heartbeat # reinstallarlo in caso di errori
2) vi /etc/ha.d/authkeys # creare il certificato
auth 1
1 crc
1 crc
chmod 600 /etc/ha.d/authkeys
3) andare sul server 1
vi /etc/ha.d/ha.cf
crm on
# debug log
debugfile /var/log/ha-debug
# log file
logfile /var/log/ha-log
# the way of output to syslog
logfacility local0
# keepalive
keepalive 2
# deadtime
deadtime 30
# deadping
deadping 40
# warntime
warntime 10
# initdead
initdead 60
# port
udpport 694
# interface and IP address of another Host
ucast eth1 10.0.0.22
# auto failback
auto_failback on
# node name (the name of "uname -n")
node www1.instyle.locale
node www2.instyle.locale
respawn root /usr/lib/heartbeat/pingd -m 100 -d 5s -a default_ping_set
4) Configuriamo il server 2
vi /etc/ha.d/ha.cf
crm on
debugfile /var/log/ha-debug
logfile /var/log/ha-log
logfacility local0
keepalive 2
deadtime 30
deadping 40
warntime 10
initdead 60
udpport 694
# interface and IP address of another Host
ucast eth1 10.0.0.21
auto_failback on
node www1.instyle.locale
node www2.instyle.locale
respawn root /usr/lib/heartbeat/pingd -m 100 -d 5s -a default_ping_set
5) Eseguire il seguente commando su entrambi i server:
/etc/init.d/heartbeat start
Starting High-Availability services:
[ OK ]
[root@www1 ~]#
Chkconfig heartbeat on
6) Eseguiamo il commando su entrambi i server, se il risultato è ok vuol dire che il servizio si è avviato correttamente:
crm_mon -i 3
Defaulting to one-shot mode
You need to have curses available at compile time to enable console mode
