HA高可用集群部署（ricci+luci+fence_virtd) 双机热备
主机环境 RedHat6.5 64位
实验环境 服务端1 ip 172.25.29.1 主机名：server1.example.com ricci
服务端2 ip 172.25.29.2 主机名：server2.example.com ricci
管理端1 ip 172.25.29.3 主机名：server3.example.com luci
管理端2 ip 172.25.29.250 fence_virtd
防火墙状态：关闭
1. 安装ricci、luci及创建节点
1.安装、开启ricci（服务端1）

[root@server1yum.repos.d]# yum install ricci -y #安装ricci
[root@server1yum.repos.d]# passwd ricci #修改ricci密码
Changingpassword for user ricci.
Newpassword:
BADPASSWORD: it is based on a dictionary word
BADPASSWORD: is too simple
Retypenew password:
passwd:all authentication tokens updated successfully.
[root@server1yum.repos.d]# /etc/init.d/ricci start #开启ricci

[root@server1yum.repos.d]# chkconfig ricci on #开机自动开启
服务端2和服务端1做相同的操作
2.安装、开启luci （管理端1）
安装之前，与服务端1一样修改yum源
[root@server3yum.repos.d]# yum install luci -y #安装luci
[root@server3yum.repos.d]# /etc/init.d/luci start #开启ruci
Startluci... [ OK ]
Pointyour web browser to https://server3.example.com:8084 (or equivalent) to accessluci
在登陆之前，必须有DNS解析，也就是在/etc/hosts添加
例如: 172.25.29.3 server3.example.com
3．创建节点
登陆 https://server3.example.com:8084 #luci开放的是8084端口
安全证书，选I Understand Risks
点击Confirm Security Excepton
进入到管理服务器的luci界面，登陆时的密码是安装luci虚拟机的root密码
选择Manage Clusters，之后点击Create创建集群
如图，Cluster Name创建集群的名称，勾选Use the Same Passwordfor All Nodes，指的是所有结点所用的是相同的密码，填写要创建的结点名称和密码，名称是服务端的主机名，密码是上面提到的passwd ricci的修改的密码。勾选Download PackagesReboot和Enable，选择Create Cluster
正在创建节点，如图
创建完成，如图
