系统 centos6.4-x86_64
前提 各节点服务器 1构建第三方源配置完毕;2搭建好rsync服务。
(第三方源 http://download.opensuse.org/repositories/network:/ha-clustering:/Stable/CentOS_CentOS-6/x86_64/)
安装基本软件（各节点服务器）
yum install -y vim git make automake gcc gcc-c++ glibc gd gd-devel glib-devel glibc-headers wget curl tar nc libcurl-devel openssl-devel zlib-devel zlib patch readline readline-devel libffi-devel curl-devel zip rsync ruby rubygems ruby-devel htop mlocate python-dateutil redhat-rpm-config ntp |
修改hosts文件，添加虚拟IP解析
vim /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 10.0.0.101 vm01-centos 10.0.0.102 vm02-centos 10.0.0.103 vm03-centos |
Install Pacemaker: (Do on all servers)
yum install -y pacemaker cman ccs corosync pssh crmsh |
添加开机启动
chkconfig pacemaker on |
Create Corosync Key: (Only do on the first server)
corosync-keygen |
Set permissions on the key: (Do first server)
chown root:root /etc/corosync/authkeychmod 400 /etc/corosync/authkey |
拷贝至其他节点
rsync –avh /etc/corosync/authkey root@10.0.0.101:/etc/corosync/authkeyrsync –avh /etc/corosync/authkey root@10.0.0.103:/etc/corosync/authkey |
Install a base corosync config: (Do on first server)
