LB/LVS之Piranha Configuration Tool 配​置 ​LVS (DR)



Piranha Configuration Tool 配​置 ​LVS （DR）
=================================================================================
Piranha Configuration Tool为​ LVS 创​​建​所​需​配​置​文​件​ —/etc/sysconfig/ha/lvs.cf

环境：
lvs-DR

1.hosts
 cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.2       active.uplook.com active
192.168.1.3       backup.uplook.com backup
192.168.1.10     node1.uplook.com node1
192.168.1.20     node2.uplook.com node2

2.cip 192.168.1.1

   dip 192.168.1.2/24
   vip 192.168.1.100/32(调度器上无需配置 软件自己分配)
  
   rip1 192.168.1.10/24  vip lo 192.168.1.100/32
   rip2 192.168.1.20/24  vip lo 192.168.1.100/32
  
3.调度器
[rhel6]
name=Red Hat Enterprise Linux
baseurl=file:///mnt/
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-beta,file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[LoadBalancer]
name=Red Hat Enterprise Linux
baseurl=file:///mnt/LoadBalancer
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-beta,file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[HighAvailability]
name=Red Hat Enterprise Linux
baseurl=file:///mnt/HighAvailability
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-beta,file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[ResilientStorage]
name=Red Hat Enterprise Linux
baseurl=file:///mnt/ResilientStorage
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-beta,file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[ScalableFileSystem]
name=Red Hat Enterprise Linux
baseurl=file:///mnt/ScalableFileSystem
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-beta,file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

yum install ipvsadm  piranha -y （主备都安装）

4.piranha-passwd
   redhat

5.[root@active ~]# /etc/init.d/piranha-gui start
[root@active ~]# chkconfig piranha-gui on
[root@active ~]# netstat -tnlp |grep :3636
tcp        0      0 :::3636                    :::*                        LISTEN      1887/httpd

6.登录192.168.1.2 ,用户名和密码如下：
  piranha 
  redhat
 
 1)监控页面  刚开始为down
 2)全局确认主调 
 

 3）冗余为备调
 
  以上为虚拟服务名称和vip捆绑接口
 
 
 
 
 
  检测脚本
 
  将配置文件lvs.cf同步到备调度器
[root@active ~]# rsync -va /etc/sysconfig/ha/lvs.cf backup:/etc/sysconfig/ha/

启动进程pulse
[root@active ~]# /etc/init.d/pulse start
[root@active ~]# chkconfig pulse on

[root@backup ~]# /etc/init.d/pulse start
[root@backup ~]# chkconfig pulse on

只有活跃的调度器上才有lvs列表 虚拟ip在主上 注意开启路由转发
