linux-ha在redhat 4.2上稳定版本heartbeat 2.0.4的安装

、redhat4.2安装，安装开发包;

、安装ipvsadm

rpm -ivh ipvsadm-1.24-5.i386.rpm

 

、安装heartbeat

rpm -ivh heartbeat-pils-2.0.4-1.el4.i386.rpm

rpm -ivh heartbeat-stonith-2.0.4-1.el4.i386.rpm

rpm -ivh heartbeat-2.0.4-1.el4.i386.rpm

rpm -ivh perl-Parse-RecDescent-1.94-1.rh.el.um.1.noarch.rpm

rpm -ivh perl-Mail-IMAPClient-2.2.9-1.rh.el.um.1.noarch.rpm

rpm -ivh perl-Digest-SHA1-2.07-5.i386.rpm

rpm -ivh perl-Digest-HMAC-1.01-13.noarch.rpm

rpm -ivh perl-Net-DNS-0.48-1.i386.rpm

rpm -ivh perl-Authen-SASL-2.08-1.rh.el.um.1.noarch.rpm

rpm -ivh perl-Net-SSLeay-1.25-3.2.el4.rf.i386.rpm

rpm -ivh perl-IO-Socket-SSL-0.96-1.rh.el.um.1.noarch.rpm

rpm -e perl-LDAP

rpm -ivh perl-ldap-0.3202-1.rh.el.um.1.noarch.rpm

rpm -ivh perl-modules-5.8.5-3.i386.rpm

rpm -ivh --force perl-libnet-1.19-3.noarch.rpm  ##(用force的原因：安装包中man3里有10个文件与包perl.5.8.5-16中的相同)

rpm -ivh heartbeat-ldirectord-2.0.4-1.el4.i386.rpm

   群集公共地址         vip=192.168.2.3

   群集ha节点1(主): 主机名mxb6    eth0=192.168.2.6/24        eth1=192.168.3.6/24

   群集ha节点2(备): 主机名mxb7   eth0=192.168.2.7/24        eth1=192.168.3.7/24

 

   真实应用服务器1: eth0=192.168.2.20/24                lo:0=192.168.2.5/32

   真实应用服务器2: eth0=192.168.2.21/24                lo:0=192.168.2.5/32

ha配置文件样例在/usr/share/doc/heartbeat-2.0.4目录里

将文件ha.cf,haresource,authkey文件复制到 /etc/ha.d/

ldirectord样例文件在/usr/share/doc/heartbeat-ldirectord-2.0.4目录

将ldirectord.cf复制到/etc/ha.d/

然后按下面的内容进行配置.
