linux-ha heartbeat高可用的安装配置（http服务高可用）

heartbeat工作原理：本次实验，使用广播地址225.0.0.11 694作为heartbeat的网络心跳地址，heartbeat通过网络心跳监测对端服务是否正常， 通过/etc/ha.d/ha.cf 文件的deadtime参数判断对端服务中断，通过参数auto_failback参数控制资源失败自动接管，从而完成httpd服务的双机互备。 两台主机（一台是rhel6.4 arbiter，一台是centos6.8 mymongo1） 一、两台主机的基本信息，重点是hosts文件的IP地址主机名解析 [root@mymongo1 ~]# uname -a Linux mymongo1 2.6.32-642.el6.x86_64 #1 SMP Tue May 10 17:27:01 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux [root@mymongo1 ~]# hostname mymongo1 [root@mymongo1 ~]# cat /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost #::1 localhost6.localdomain6 localhost6 192.168.144.111 arbiter 192.168.144.132 mymongo1 [root@mymongo1 ~]# ifconfig -a eth0 Link encap:Ethernet HWaddr 00:0C:29:40:94:8E inet addr:192.168.199.131 Bcast:192.168.199.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe40:948e/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:46 errors:0 dropped:0 overruns:0 frame:0 TX packets:30 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4219 (4.1 KiB) TX bytes:3299 (3.2 KiB) eth1 Link encap:Ethernet HWaddr 00:0C:29:40:94:98 inet addr:192.168.144.132 Bcast:192.168.144.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe40:9498/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1890 errors:0 dropped:0 overruns:0 frame:0 TX packets:1800 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:253127 (247.1 KiB) TX bytes:252326 (246.4 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:8 errors:0 dropped:0 overruns:0 frame:0 TX packets:8 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:576 (576.0 b) TX bytes:576 (576.0 b) [root@mymongo1 ~]#

二、heartbeat的安装，rhel和centos安装不一样，先安装centos机器的heartbeat 注意：最少保证2台主机中的centos主机能够上网，centos安装Heartbeats，通过yum方式网络安装 1、首先下载epel-release-6-8.noarch.rpm wget http://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm [root@mymongo1 ~]# ls amoeba Documents install.log mysql-5.6.36.tar.gz Pictures Videos anaconda-ks.cfg Downloads install.log.syslog mysql-proxy-0.8.2 Public arbiter epel-release-6-8.noarch.rpm lua-5.1.4 mysql-proxy-0.8.2.tar.gz Templates cmake-2.8.10.2.tar.gz glib-2.22.5 lua-5.1.4.tar.gz mysql-proxy-0.8.5 test1.sh Desktop glib-2.22.5.tar Music mysql-proxy-0.8.5.tar.gz test.sh [root@mymongo1 ~]# --安装epel，其实是安装yum源 rpm -ivh epel-release-6-8.noarch.rpm [root@mymongo1 yum.repos.d]# pwd /etc/yum.repos.d [root@mymongo1 yum.repos.d]# ls CentOS-Base.repo CentOS-Debuginfo.repo CentOS-fasttrack.repo CentOS-Media.repo CentOS-Vault.repoepel.repo epel-testing.repo [root@mymongo1 yum.repos.d]# [root@mymongo1 yum.repos.d]# cat epel.repo [epel] name=Extra Packages for Enterprise Linux 6 - $basearch #baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch failovermethod=priority enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

2、在rhel机器上arbiter安装heartbeat，方法是将centos机器mymongo1上的heartbeat包及其依赖包scp到arbiter机器上， 使用rpm -ivh方式安装，安装过程（安装过程中需要其他依赖的rpm包，可以挂载centos cd1镜像到arbiter上找到安装即可）： [root@arbiter heartbeat]# ls
