rhel+heartbeatv2+apache+share_storage

共享存储配置就不写了

1.add user on node1/2
[root@node1 ~]# groupadd -g 666 haclient
[root@node1 ~]# useradd -u 666 -g haclient hacluster
[root@node1 ~]# echo "hacluster" | passwd hacluster --stdin

2.install libnet.tar.gz on node1/2

3.install heartbeat.tar.gz on node1/2

chkconfig  heartbeat on

4.install watchdog

yum install watchdog
/etc/init.d/watchdog  start
chkconfig watchdog on
echo "modprobe softdog" >> /etc/rc.local
modprobe softdog
lsmod | grep soft
ll /dev/watchdog
echo "kernel.panic = 60" >>  /etc/sysctl.conf

5.mkdir log dir on node1/2
mkdir /var/log/ha_log
chmod -R 777 /var/log/ha_log/

6.修改heartbeat配置文件
主配置文件

cat > /usr/local/etc/ha.d/ha.cf <
logfile /var/log/ha_log/ha-log.log
debugfile /var/log/ha_log/ha-debug.log
bcast eth1
keepalive 1
warntime 3
deadtime 10
initdead 120
hopfudge 1
udpport 694
auto_failback off
watchdog /dev/watchdog
node node1  #uname -n
node node2  #uname -n
ping  192.168.0.136
deadping 5
crm respawn
EOF

资源管理配置文件

cat > /usr/local/etc/ha.d/haresources <
node1 192.168.0.1 mount httpd
EOF

配置heartbeat的认证文件

cat > /usr/local/etc/ha.d/authkeys <<EOF
auth 1
1 crc
EOF
chmod 600 /usr/local/etc/ha.d/authkeys

7.增加mount脚本,安装apache

cat > /etc/init.d/mount <
#!/bin/bash
logger $0 called with $1
case "$1" in
start)
mount  /dev/mapper/vgdrbd-lvh0  /var/www/html
;;
stop)
umount  /var/www/html
;;
status)
df -hP|column -t| grep html
;;
esac
EOF

cp /etc/init.d/mount  /etc/ha.d/resource.d
yum install httpd

8.同步2台服务器配置文件（修改后同步上面3个文件）
/usr/local/lib/heartbeat/ha_propagate

#!/usr/bin/python
# /usr/local/lib/heartbeat/ha_propagate
import os, sys
from stat import *

cfgdir = "/usr/local/etc/ha.d/"
cfgfile = cfgdir + "ha.cf"
authfile = cfgdir + "authkeys"
harefile = cfgdir + "haresources"

try:
        os.stat(cfgfile)
        os.stat(authfile)
except:
        print "HA Linux not configured on this node.  Can not propagate."
        sys.exit()

nodes = []

f=open(cfgfile)
for line in f:
    if line.startswith("node"):
       toks = line.split()
       if (len(toks) == 2):
          nodeName = toks[1]
          nodes.append(nodeName)
f.close()

thisnode = os.uname()[1]
if nodes.count(thisnode) > 0:
   nodes.remove(thisnode)

for i, v in enumerate(nodes):
    print "Propagating HA configuration files to node " + v + "."
    res = os.system("scp " + cfgfile + " " + authfile + " " + harefile + " root@" + v + ":" + cfgdir)
    print "Setting HA startup configuration on node " + v + "."
    res = os.system("ssh " + " root@" + v + " chkconfig --add  heartbeat")

9.拷贝认证文件，hb_gui才能通过pam登陆

cp /usr/local/etc/pam.d/hbmgmtd  /etc/pam.d/

10.图形界面设置了

hb_gui &
