1、准备环境

1.1、配置yum源配置文件

mount -t auto /dev/cdrom  /mntrm -rf /etc/yum.repos.d/
mkdir -p /etc/yum.repos.d/cat >> /etc/yum.repos.d/rhel-Media.repo<<EOF
# rhel-Media.repo
#
#  This repo can be used with mounted DVD media, verify the mount point for
#  rhel-7.  You can use this repo and yum to install items directly off the
#  DVD ISO that we release.
#
# To use this repo, put in your DVD and use it with the other repos too:
#  yum --enablerepo=c7-media [command]
#
# or for ONLY the media repo, do this:
#
#  yum --disablerepo=\* --enablerepo=rhel7-media [command][rhel7-media]
name=rhel-$releasever - Media
baseurl=file:///mnt/
gpgcheck=0
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rhel-7
EOFyum clean all
yum makecache

1.2、安装依赖包

mount -t auto /dev/cdrom  /mnt yum -y install gcc make binutils gcc-c++ compat-libstdc++-33 elfutils-libelf-devel elfutils-libelf-devel-static elfutils-libelf-devel ksh libaio libaio-devel numactl-devel sysstat unixODBC unixODBC-devel pcre-devel libXext* unzip chrony pacemaker pcs fence-agents-all httpd sbd device-mapper device-mapper-multipathyum install pcs-0.9.162-5.el7.x86_64.rpm  pacemaker-1.1.18-11.el7.x86_64.rpm  pacemaker-cli-1.1.18-11.el7.x86_64.rpm  pacemaker-cluster-libs-1.1.18-11.el7.x86_64.rpm   pacemaker-cluster-libs-1.1.18-11.el7.x86_64.rpm  corosync-2.4.3-2.el7.x86_64.rpm  corosynclib-2.4.3-2.el7.x86_64.rpm  pacemaker-libs-1.1.18-11.el7.x86_64.rpm  resource-agents-3.9.5-124.el7.x86_64.rpm  python-clufter-0.77.0-2.el7.noarch.rpm   clufter-bin-0.77.0-2.el7.x86_64.rpm  clufter-common-0.77.0-2.el7.noarch.rpm

1.3、关闭防火墙以及selinux

sed -i 's/=enforcing/=disabled/g' /etc/selinux/config
setenforce 0
getenforcesystemctl stop firewalld
systemctl disable firewalld

1.4、绑定网卡名称

cat >/etc/udev/rules.d/70-persistent-net.rules<<EOF
SUBSYSTEM=="net",ACTION=="add",DRIVERS=="?*",ATTR{address}=="00:0c:29:46:37:a8",ATTR{type}=="1",KERNEL=="eth*",NAME="eth0"

SUBSYSTEM=="net",ACTION=="add",DRIVERS=="?*",ATTR{address}=="00:0c:29:46:37:c6",ATTR{type}=="1",KERNEL=="eth*",NAME="eth3"
EOFsed -i 's/quiet/quiet net.ifnames=0 biosdevname=0/g'  /etc/default/grub
cat  /etc/default/grub
grub2-mkconfig -o /boot/grub2/grub.cfg

1.5、配置网卡bond

    systemctl stop  NetworkManager
systemctl disable   NetworkManager cat >/etc/sysconfig/network-scripts/ifcfg-bond0<<EOF1
BOOTPROTO=static
DEVICE=bond0
IPADDR=192.168.33.10

1.6、配置/etc/hosts

hostnamectl set-hostname  xmcs01cat >>/etc/hosts<<EOF
192.168.33.10 xmcs01
192.168.33.11 xmcs02

192.168.1.10 xmcs01fc
192.168.1.11 xmcs02fc
EOFcat /etc/hosts

1.7、配置共享盘

yum install device-mapper-multipath
设置开机启动
systemctl enable multipathd.service
添加配置文件
需要multipath正常工作只需要如下配置即可，如果想要了解详细的配置，请参考Multipath# vi /etc/multipath.conf
blacklist {devnode "^sda"
}
defaults {user_friendly_names yespath_grouping_policy multibusfailback immediateno_path_retry failfind_multipaths yesreservation_key 0x1
}
启动服务
systemctl restart multipathd.servicefdisk /dev/sdb---n---p---1----t---8e--w创建PV
pvcreate /dev/sdb1pvdisplay /dev/sdb1vgcreate vg01 /dev/sdb1创建LV
lvcreate -l 100%VG -n lvol1 vg01mkfs.xfs /dev/vg01/lvol1mkdir /datamount /dev/vg01/lvol1 /data

2、初始化cluster

2.1、启动服务

在每一台上启动服务systemctl enable chronydsystemctl start chronydsystemctl status chronydecho "redhat" |passwd --stdin haclustersystemctl start pcsdsystemctl enable pcsdsystemctl start pcsd.service    systemctl status pcsd.service

2.2、验证hacluster用户

# 节点1    认证配置
pcs cluster auth xmcs01 xmcs02 -u hacluster -p redhat[root@xmcs01 ~]# pcs cluster auth xmcs01 xmcs02 -u hacluster -p redhat
xmcs01: Authorized
xmcs02: Authorized

2.3、创建cluster

# 节点1  生成集群文件，另一节点会自动生成
pcs cluster setup --name mycluster xmcs01 xmcs02 [root@xmcs01 ~]# pcs cluster setup --name mycluster xmcs01 xmcs02
Destroying cluster on nodes: xmcs01, xmcs02...

}quorum {provider: corosync_votequorumtwo_node: 1
}logging {to_logfile: yeslogfile: /var/log/cluster/corosync.logto_syslog: yes
}

2.4、配置web登录

vi /usr/lib/pcsd/ssl.rbwebrick_options = {:Port               => 2224,:BindAddress        => '0.0.0.0',:Host               => '0.0.0.0',:SSLEnable          => true,:SSLVerifyClient    => OpenSSL::SSL::VERIFY_NONE,:SSLCertificate     => OpenSSL::X509::Certificate.new(crt),:SSLPrivateKey      => OpenSSL::PKey::RSA.new(key),:SSLCertName        => [[ "CN", server_name ]],:SSLOptions         => get_ssl_options(),}scp /usr/lib/pcsd/ssl.rb xmcs02:/usr/lib/pcsd/ssl.rbpcs cluster start --all
pcs cluster enable --allsystemctl enable pcsdsystemctl restart pcsd# netstat -tunlp     # 查看 2224 端口是否启用# web 端登录  https://192.168.33.10:2224# 输入账号密码  hacluster / redhat

配置多心跳


[root@xmcs01 ~]# cat /etc/corosync/corosync.conf
totem {version: 2cluster_name: myclustersecauth: offtransport: udpu
rrp_mode: passive
interface {
ringnumber: 0

开放lvmha功能 (sheng)

lvmconf --enable-halvm --services --startstopservices[root@xmcs01 ~]# lvmconf --enable-halvm --services --startstopservices
Warning: Stopping lvm2-lvmetad.service, but it can still be activated by:lvm2-lvmetad.socket

3、配置cluster
