四、安裝集群軟件
兩個(gè)節(jié)點(diǎn)上都要做的
#yum install corosync pacemaker -y //由于是網(wǎng)絡(luò)鏡像，會(huì)比較慢，耐心等會(huì)吧！

安裝完成之后就是配置了，注意配置的時(shí)候選擇的端口和地址不能跟已存在的集群沖突，所

以我就做了一下簡(jiǎn)單的設(shè)置
#export ais_port=4000
#export ais_mcast=226.94.1.1

接下來(lái)就是配置corosync了：
#cd /etc/corosync/
#cp corosync.conf.example corosync.conf
#vim !$ 把配置改成如下
# Please read the corosync.conf.5 manual page
compatibility: whitetank

totem {
 version: 2
 secauth: on
 threads: 0
 interface {
  ringnumber: 0
  bindnetaddr: 192.168.1.0   //指定集群所在的網(wǎng)段的網(wǎng)絡(luò)號(hào)
  mcastaddr: 226.94.1.1  //組播地址
  mcastport: 4000  //端口號(hào)
  ttl: 1
 }
}

logging {
 fileline: off
 to_stderr: no
 to_logfile: yes
 to_syslog: no
 logfile: /var/log/cluster/corosync.log
 debug: off
 timestamp: on
 logger_subsys {
  subsys: AMF
  debug: off
 }
}
amf {
 mode: disabled
}
####以下是添加的內(nèi)容
service {
 ver: 1    //定義pacemaker的版本，fedora上使用版本1，而在redhat上可以

使用0
 name: pacemaker 
}
aisexec {
        user:   root
        group:  root
}
其中注釋的內(nèi)容為所修改的內(nèi)容
配置完成之后，拷貝一個(gè)到另一個(gè)節(jié)點(diǎn)上
#scp -p  /etc/corosync/corosync.conf node2:/etc/corosync/

確保沒(méi)有錯(cuò)誤的情況下，可以在HA1上啟動(dòng)了，啟動(dòng)之后還要進(jìn)行一些列的檢測(cè)
#/etc/init.d/corosync start

添加認(rèn)證密鑰
#corosync-keygen  //這個(gè)要是新機(jī)器的話(huà)，時(shí)間會(huì)長(zhǎng)一點(diǎn)，要有點(diǎn)耐性等待！
#scp -p authkeys corosync.conf node2:/etc/corosync/
配置完成之后，現(xiàn)在HA1上啟動(dòng)corosync：
#server corosync start
Starting corosync (via systemctl):                         [  OK  ] oK，corosync

服務(wù)啟動(dòng)成功！
接下來(lái)就是檢測(cè)集群是否正確啟動(dòng)并且已經(jīng)可以和其他節(jié)點(diǎn)建立集群關(guān)系了：
查看corosync引擎是否正常啟動(dòng)：
[root@node1 ~]# grep -e "Corosync Cluster Engine" -e "configuration file"

/var/log/messages
Sep 18 23:09:44 node1 smartd[786]: Opened configuration file /etc/smartd.conf
Sep 19 13:41:03 node1 smartd[801]: Opened configuration file /etc/smartd.conf
Sep 19 20:44:55 node1 smartd[680]: Opened configuration file /etc/smartd.conf
[root@node1 ~]# grep -e "Corosync Cluster Engine" -e "configuration file"

/var/log/cluster/corosync.log 
Sep 18 17:12:06 corosync [MAIN  ] Corosync Cluster Engine ('1.4.1'): started and

ready to provide service.
Sep 18 17:12:06 corosync [MAIN  ] Successfully read main configuration file

'/etc/corosync/corosync.conf'.
Sep 18 17:12:06 corosync [MAIN  ] Corosync Cluster Engine exiting with status 8

at main.c:1702.
Sep 18 17:16:11 corosync [MAIN  ] Corosync Cluster Engine ('1.4.1'): started and

ready to provide service.

查看初始化成員節(jié)點(diǎn)通知是否正常發(fā)出：
[root@node1 ~]#  grep TOTEM /var/log/cluster/corosync.log

檢查啟動(dòng)過(guò)程中是否有錯(cuò)誤產(chǎn)生：
[root@node2 ~]# grep ERROR: /var/log/cluster/corosync.log | grep -v

unpack_resources

查看pacemaker是否正常啟動(dòng)：
[root@node1 ~]# grep pcmk_startup /var/log/cluster/corosync.log 
Sep 19 13:48:48 corosync [pcmk  ] info: pcmk_startup: CRM: Initialized
Sep 19 13:48:48 corosync [pcmk  ] Logging: Initialized pcmk_startup
Sep 19 13:48:48 corosync [pcmk  ] info: pcmk_startup: Maximum core file size is:

4294967295
Sep 19 13:48:48 corosync [pcmk  ] info: pcmk_startup: Service: 9
Sep 19 13:48:48 corosync [pcmk  ] info: pcmk_startup: Local hostname: node1.luo
檢查完畢，接下來(lái)就可以啟動(dòng)另一個(gè)節(jié)點(diǎn)了，最好在同一個(gè)節(jié)點(diǎn)上啟動(dòng)所有的其他的集群節(jié)

點(diǎn)：
[root@node1 ~]# ssh node2 -- '/etc/init.d/corosync start'
Starting corosync (via systemctl):  [  OK  ]
啟動(dòng)成功了！

接下來(lái)就是啟動(dòng)pacemaker了！
[root@node1 corosync]# /etc/init.d/pacemaker  start
Starting pacemaker (via systemctl):                        [  OK  ]
ok，同樣啟動(dòng)成功

# ps axf //查看進(jìn)程
 1724 ?        R      5:59 /usr/lib/heartbeat/stonithd
 1725 ?        R      5:59 /usr/lib/heartbeat/cib
 1726 ?        S      0:00 /usr/lib/heartbeat/lrmd
 1727 ?        R      5:59 /usr/lib/heartbeat/attrd
 1728 ?        S      0:00 /usr/lib/heartbeat/pengine
 1729 ?        R      5:59 /usr/lib/heartbeat/crmd
可以看出已經(jīng)有進(jìn)程了

當(dāng)然這個(gè)時(shí)候有個(gè)關(guān)鍵性的設(shè)置，就是關(guān)閉防火墻，如果你沒(méi)有關(guān)閉防火墻功能，下面將會(huì)

給你帶來(lái)很大的麻煩，我開(kāi)始就是沒(méi)有關(guān)閉防火墻，后來(lái)看日志才知道，所以你做的時(shí)候可

以把防火墻先關(guān)閉了，但是在真正應(yīng)用之中，還是要開(kāi)啟防火墻功能
#setup 然后在里面選擇Firewall configure 然后disabled就行了

接下來(lái)使用crm的內(nèi)部命令進(jìn)行查看
#crm_mon 或crm status
Online: [ node2.luowei.com node1.luowei.com ]可以看出，集群的節(jié)點(diǎn)都啟動(dòng)了

一切準(zhǔn)備停當(dāng)，接下來(lái)就是雙主集群的配置了！

五、安裝apache服務(wù)和集群文件系統(tǒng)-GFS2
為了方便驗(yàn)證，我就安裝一個(gè)apache服務(wù)用于測(cè)試：
#yum install httpd -y
在HA1上的添加測(cè)試頁(yè)面：
#echo "<h1>node1.luowei.com<h1>" >/var/www/html/index.html
在HA2上的添加測(cè)試頁(yè)面：
#echo "<h1>node2.luowei.com<h1>" >/var/www/html/index.html
然后把兩個(gè)節(jié)點(diǎn)上的/etc/httpd/conf/httpd.conf的配置文件，保持一下的內(nèi)容是開(kāi)啟的，

如果有注釋的，請(qǐng)去掉注釋
<Location /server-status>
    SetHandler server-status
    Order deny,allow
    Deny from all
    Allow from 127.0.0.1
</Location>

保證httpd服務(wù)不會(huì)隨著開(kāi)機(jī)自動(dòng)啟動(dòng)
#chkconfig httpd off

#crm configure property stonith-enabled=false  //關(guān)閉stonith設(shè)備
#crm configure property no-quorum-policy=ignore //關(guān)閉兩節(jié)點(diǎn)之間的選舉
#crm configure

為httpd添加資源
# crm configure primitive WebSite ocf:heartbeat:apache params

configfile=/etc/httpd/conf/httpd.conf op monitor interval=1min
# crm configure primitive ClusterIP ocf:heartbeat:IPaddr2 params

ip=192.168.1.110 cidr_netmask=32 op monitor interval=30s  //添加一個(gè)虛擬IP
[root@node1 ~]# crm status
============
Last updated: Mon Sep 19 23:44:05 2011

Current DC: node2.luowei.com - partition with quorum
Version: 1.1.5-1.fc15-01e86afaaa6d4a8c4836f68df80ababd6ca3902f
2 Nodes configured, 2 expected votes
2 Resources configured.
============

Online: [ node2.luowei.com node1.luowei.com ]

 ClusterIP (ocf::heartbeat:IPaddr2): Started node1.luowei.com
 WebSite (ocf::heartbeat:apache): Started node2.luowei.com
可以看到兩個(gè)資源不在同一個(gè)節(jié)點(diǎn)上，所以需要做一下的設(shè)置：
#crm configure colocation website-with-ip INFINITY: WebSite ClusterIP  //做一個(gè)

位置約束
然后再使用crm status 查看資源已經(jīng)都流轉(zhuǎn)到同一個(gè)節(jié)點(diǎn)上了，如下所示
Online: [ node2.luowei.com node1.luowei.com ]

 ClusterIP (ocf::heartbeat:IPaddr2): Started node1.luowei.com
 WebSite (ocf::heartbeat:apache): Started node1.luowei.com
還要控制資源的啟動(dòng)停止順序
#crm configure order apache-after-ip mandatory: ClusterIP WebSite  //定義ip的資

源要在apache的服務(wù)啟動(dòng)之前啟動(dòng)

指定優(yōu)先的Location
#crm configure location prefer-pcmk-l WebSite 50: node1.luowei.com

#crm configure show  //查看一下自己的配置如下
[root@node1 ~]# crm configure show
node node1.luowei.com
node node2.luowei.com
primitive ClusterIP ocf:heartbeat:IPaddr2 \
 params ip="192.168.1.110" cidr_netmask="32" \
 op monitor interval="30s"
primitive WebSite ocf:heartbeat:apache \
 params configfile="/etc/httpd/conf/httpd.conf" \
 op monitor interval="1min"

 expected-quorum-votes="2" \
 stonith-enabled="false" \
 no-quorum-policy="ignore"
rsc_defaults $id="rsc-options" \
 resource-stickiness="100"
如上圖所示，資源已經(jīng)啟動(dòng)了，所以接下來(lái)就可以往下做了！
可以在瀏覽其中輸入http://192.168.1.110可以訪問(wèn)web服務(wù)了！

 

六、安裝DRBD軟件包
DRBD實(shí)現(xiàn)節(jié)點(diǎn)之間的數(shù)據(jù)同步的，實(shí)現(xiàn)備份功能。
1.# yum install drbd-pacemaker drbd-udev -y
2.安裝完drbd之后，首先要在兩個(gè)節(jié)點(diǎn)上做一個(gè)單獨(dú)的磁盤(pán)分區(qū)來(lái)存放數(shù)據(jù)
這里我用一塊新的磁盤(pán)（/dev/sdb）進(jìn)行實(shí)驗(yàn)，劃分磁盤(pán)分區(qū)如下所示：
#fdisk /dev/sdb
[root@node1 ~]# fdisk /dev/sda1
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF

disklabel
Building a new DOS disklabel with disk identifier 0xcaf34d49.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

Command (m for help): p

Disk /dev/sda1: 524 MB, 524288000 bytes
255 heads, 63 sectors/track, 63 cylinders, total 1024000 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xcaf34d49

     Device Boot      Start         End      Blocks   Id  System

Command (m for help): p

     Device Boot      Start         End      Blocks   Id  System

Command (m for help): q
# partprobe /dev/sdb
# pvcreate /dev/sdb1
# vgcreate VolGroupb /dev/sdb1
# lvcreate -n drbd-demo -L 1G VolGroupb
[root@node1 ~]# lvs
  LV        VG        Attr   LSize  Origin Snap%  Move Log Copy%  Convert
  lv_root   VolGroup  -wi-ao 17.56g                                      
  lv_swap   VolGroup  -wi-ao  1.94g                                      
  drbd-demo VolGroupb -wi-a-  1.00g  
ok!HA1上的邏輯卷做好了，這個(gè)過(guò)程也要在HA2上來(lái)一遍，我就不多展示了！

3.準(zhǔn)備完成，接下來(lái)就是配置DRBD了！
#vim /etc/drbd.conf
include "drbd.d/global_common.conf";
include "drbd.d/*.res";

global {
        usage-count yes;
}
common {
        protocol C;
}
resource wwwdata {
        meta-disk internal;
        device  /dev/drbd1;
        syncer {
                verify-alg sha1;
        }
        net {
        allow-two-primaries;
        }
        on node1.luowei.com {
                disk    /dev/mapper/VolGroupb-drbd--demo;
                address 192.168.1.78:7789;    //定義HA1節(jié)點(diǎn)的
        }
        on node2.luowei.com {
                disk    /dev/mapper/VolGroupb-drbd--demo;
                address 192.168.1.151:7789;   //定義HA2節(jié)點(diǎn)的
        }
}

4.接下來(lái)就是初始化并加載DRBD了
# drbdadm create-md wwwdata
New drbd meta data block successfully created.
初始化成功！

5.接下來(lái)查看DRBD的模塊載入內(nèi)核并檢測(cè)是不是都正常
[root@node1 ~]# modprobe drbd
[root@node1 ~]# drbdadm up wwwdata
[root@node1 ~]# cat /proc/drbd 
version: 8.3.9 (api:88/proto:86-95)
srcversion: CF228D42875CF3A43F2945A 
 1: cs:WFConnection ro:Secondary/Unknown ds:Inconsistent/DUnknown C r----s
    ns:0 nr:0 dw:0 dr:0 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:1048508
可以看出已經(jīng)出現(xiàn)了Secondary了，下面在第二個(gè)節(jié)點(diǎn)上使用上面同樣的方法進(jìn)行模塊載入

并檢測(cè)，此處省略.....

6.然后在任意一個(gè)節(jié)點(diǎn)上查看，現(xiàn)在兩個(gè)都已經(jīng)是Secondary了，所以一切正常
[root@node1 ~]# drbd-overview 
  1:wwwdata  Connected Secondary/Secondary Inconsistent/Inconsistent C r-----

7.現(xiàn)在我們把HA1設(shè)置為主節(jié)點(diǎn)
[root@node1 ~]# drbdadm -- --overwrite-data-of-peer primary wwwdata
然后使用如下命令可以實(shí)時(shí)監(jiān)視這整個(gè)數(shù)據(jù)從主節(jié)點(diǎn)想備用節(jié)點(diǎn)上拷貝數(shù)據(jù)的過(guò)程：
[root@node1 ~]# watch -n 1 'drbd-overview' 
  1:wwwdata  SyncSource Primary/Secondary UpToDate/Inconsistent C r----- 
 [==>.................] sync'ed:  0.8% (1042492/1048508)K
  1:wwwdata  Connected Primary/Secondary UpToDate/UpToDate C r-----完成了數(shù)據(jù)的

同步，現(xiàn)在HA1處于Primary狀態(tài)，它允許寫(xiě)入了，可以在上面創(chuàng)建文件系統(tǒng)并把一些數(shù)據(jù)放

進(jìn)去了。

8.向DRBD中添加數(shù)據(jù)：
[root@node1 ~]# mkfs.ext4 /dev/drbd1  //格式化分區(qū)
[root@node1 ~]# mount /dev/drbd1 /mnt/   //掛載分區(qū)
[root@node1 ~]# echo "<h2>drbd test page</h2>" >/mnt/index.html
[root@node1 ~]# umount /mnt/   //卸載分區(qū)

9.在集群中配置DRBD
[root@node1 ~]# crm 
crm(live)# cib new drbd
crm(drbd)# configure
crm(drbd)configure# primitive WebData ocf:linbit:drbd  params

drbd_resource=wwwdata op monitor interval=60s
crm(drbd)configure# ms WebDataClone WebData meta master-max=1 master-node-max=1

clone-max=2 clone-node-max=1 notify=true 
crm(drbd)configure#commit
[root@node1 ~]# crm status

有上面的輸出信息可以看出，資源啟動(dòng)正常，但是我們注意到drbd的主節(jié)點(diǎn)在HA2上，為了

統(tǒng)一到同一個(gè)節(jié)點(diǎn)上，還需要進(jìn)一步約束資源
[root@node1 ~]# crm 
crm(live)# configure 
crm(live)configure# primitive WebFS ocf:heartbeat:Filesystem params

device="/dev/drbd/by-res/wwwdata" directory="/var/www/html" fstype="ext4"

WebFS:start
crm(live)configure# colocation WebSite-with-WebFS inf: WebSite WebFS 
crm(live)configure# order WebSite-after-WebFS inf: WebFS WebSite

再次查看，如下內(nèi)容：

 WebFS (ocf::heartbeat:Filesystem): Started node2.luowei.com
我們可以看出，資源都在同一個(gè)節(jié)點(diǎn)上

 

七、接下來(lái)就是在上面的基礎(chǔ)之上做雙主模式的集群了：
1、安裝集群文件系統(tǒng)
#yum install gfs2-utils gfs2-cluster gfs-pcmk  //兩個(gè)節(jié)點(diǎn)上都要進(jìn)行安裝的

2、添加DLM服務(wù)
[root@node1 ~]# crm 
crm(live)# configure 
crm(live)configure# primitive dlm ocf:pacemaker:controld op monitor

interval=120s
crm(live)configure# clone dlm-clone dlm meta interleave=true
crm(live)configure# commit

3、創(chuàng)建gfs-control這個(gè)集群資源：
[root@node1 ~]# clear
[root@node1 ~]# crm 
crm(live)# configure 
crm(live)configure# primitive gfs-control ocf:pacemaker:controld params

daemon=gfs_controld.pcmk args="-g 0" op monitor interval=120s
crm(live)configure# clone gfs-clone gfs-control meta interleave=true
crm(live)configure# colocation gfs-with-dlm INFINITY: gfs-clone dlm-clone 
crm(live)configure# order start-gfs-after-dlm mandatory: dlm-clone gfs-clone 
crm(live)configure# commit
然后查看一下我們的配置如下所示：
#crm configure show

WebFS   (ocf::heartbeat:Filesystem):    Started node1.luowei.com

4、創(chuàng)建GFS2文件系統(tǒng)
[root@node1 ~]# crm_resource --resource WebFS --set-parameter target-role --meta

--parameter-value Stopped 
這個(gè)時(shí)候使用crm status可以看到apache 和WebFS兩個(gè)資源都已經(jīng)停止。

5、創(chuàng)建并遷移數(shù)據(jù)到GFS2分區(qū)
在兩個(gè)節(jié)點(diǎn)上都執(zhí)行以下命令：
[root@node2 ~]# mkfs.gfs2 -p lock_dlm -j 2 -t pcmk:web /dev/drbd1
This will destroy any data on /dev/drbd1.
It appears to contain: Linux rev 1.0 ext4 filesystem data, UUID=19976683-c802-

479c-854d-e786617be523 (extents) (large files) (huge files)

Are you sure you want to proceed? [y/n] y

6、然后遷移數(shù)據(jù)到這個(gè)新的文件系統(tǒng)并且為集群重新配置GFS2
[root@node1 ~]# crm 
crm(live)# configure 
crm(live)configure# primitive WebFS ocf:heartbeat:Filesystem params

device="/dev/drbd/by-res/wwwdata" directory="/var/www/html" fstype="gfs2"
crm(live)configure# colocation WebSite-with-WebFS inf: WebSite WebFS
crm(live)configure# colocation fs_on_debd inf: WebFS WebDataClone:Master
crm(live)configure# order WebFS-after-WebData inf: WebDataClone:promote

WebFS:start
crm(live)configure# order WebSite-after-WebFS inf: WebFS WebSite
crm(live)configure# colocation WebFS-with-gfs-control INFINITY: WebFS gfs-clone
crm(live)configure# order start-WebFS-after-gfs-control mandatory: gfs-clone

WebFS
crm(live)configure# commit

7、重新配置pacemaker為Active/Active
[root@node1 ~]# crm 
crm(live)# configure clone WebIP ClusterIP meta globally-unique="true" clone-

max="2" clone-node-max="2"
crm(live)# configure primitive ClusterIP ocf:heartbeat:IPaddr2 params

ip="192.168.1.110" cidr_netmask="32" clusterip_hash="sourceip" op monitor

interval="30s" //設(shè)置ClusterIP的參數(shù)
crm(live)# configure clone WebFSClone WebFS
crm(live)# configure clone WebSiteClone WebSite
同時(shí)把CIB文件中的master-max改為2
資源配置完成，

主從到主主集群架構(gòu)就這樣配置完成！
