corosync+drbd实现mariadb高可用集群
浏览数：38 /
时间：2015年06月12日
配置前的准备
（1）节点间时间必须同步：使用ntp协议实现；
[root@node1 ~]# ntpdate 172.16.0.1 #172.16.0.1是我这里的时间服务器 [root@node2 ~]# ntpdate 172.16.0.1
（2） 节点间需要通过主机名互相通信，必须解析主机至IP地址；
(a)建议名称解析功能使用hosts文件来实现；
(b)通信中使用的名字与节点名字必须保持一致：“uname -n”命令，或“hostname”展示出的名字保持一致；
[root@node1 ~]# sed -i‘s@\(HOSTNAME=\).*@\1node1.xmfb.com@g‘ /etc/sysconfig/network [root@node1 ~]# hostname node1.xmfb.com [root@node1 ~]# echo "172.16.4.100node1.xmfb.com node1" >> /etc/hosts [root@node1 ~]# echo "172.16.4.101node2.xmfb.com node2" >> /etc/hosts [root@node2 ~]# sed -i‘s@\(HOSTNAME=\).*@\1node2.xmfb.com@g‘ /etc/sysconfig/network [root@node2 ~]# hostname node2.xmfb.com [root@node2 ~]# echo "172.16.4.100 node1.xmfb.comnode1" >> /etc/hosts [root@node2 ~]# echo "172.16.4.101node2.xmfb.com node2" >> /etc/hosts
（3）考虑仲裁设备是否会用到；
（4） 建立各节点之间的root用户能够基于密钥认证；
#ssh-keygen -t rsa -P ‘‘
#ssh-copy-id -i /root/.ssh/id_rsa.pub root@HOSTNAME
[root@node1 ~]# ssh-keygen -t rsa -f ~/.ssh/id_rsa-P ‘‘ [root@node1 ~]# ssh-copy-id -i .ssh/id_rsa.pubnode2 [root@node2 ~]# ssh-keygen -t rsa -f ~/.ssh/id_rsa-P ‘‘ [root@node2 ~]# ssh-copy-id -i .ssh/id_rsa.pubnode1
注意：定义成为集群服务中的资源，一定不能开机自动启动；因为它们将由crm管理；
Corosync配置
安装corosync
[root@node1~]# yum -y install corosync pacemaker [root@node2~]# yum -y install corosync pacemaker
安装crm
[root@node1 ~]# yum--nogpgcheck localinstall crmsh-2.1-1.6.x86_64.rpm pssh-2.3.1-2.el6.x86_64.rpm –y [root@node2 ~]# yum --nogpgcheck localinstallcrmsh-2.1-1.6.x86_64.rpm pssh-2.3.1-2.el6.x86_64.rpm -y
复制配置文件模版
[root@node1 ~]# cp/etc/corosync/corosync.conf.example /etc/corosync/corosync.conf
修改配置文件
[root@node1 ~]# vim /etc/corosync/corosync.conf

}生成验证密钥
[root@node1 ~]# corosync-keygen
复制配置文件和密钥到节点2
[root@node1 ~]# scp/etc/corosync/{authkey,corosync.conf} node2:/etc/corosync/
authkey 100% 128 0.1KB/s 00:00
corosync.conf 100% 2790 2.7KB/s 00:00启动corosync
[root@node1 ~]# service corosync start;ssh node2‘service corosync start‘
查看集群状态信息
[root@node1 ~]# crm status Last updated: Sun May 31 17:32:28 2015 Last change: Sun May 31 17:32:22 2015 Stack: classic openais (with plugin) Current DC: node1.xmfb.com - partition with quorum Version: 1.1.11-97629de 2 Nodes configured, 2 expected votes 0 Resources configured Online: [ node1.xmfb.com node2.xmfb.com ]
解决corosync中STONITH报错问题
crm(live)configure# property stonith-enabled=false crm(live)configure# commit
资源转移配置
crm(live)configure# property no-quorum-policy=ignore
资源粘性配置
crm(live)configure# propertydefault-resource-stickiness=50
Corosync就先配置到这里，然后配置drbd
drbd配置
配置之前需要配置好做drbd磁盘的分区，而且不要格式化（此处省略）
安装配置drbd
安装drbd
rpm -ivh kmod-drbd84-8.4.5-504.1.el6.x86_64.rpmdrbd84-utils-8.9.1-1.el6.elrepo.x86_64.rpm
配置global_common.conf
[root@node1 ~]# vim /etc/drbd.d/global_common.conf
global {
usage-count no;
# minor-countdialog-refresh disable-ip-verification
}
common {
protocol C;
handlers {
pri-on-incon-degr "/usr/lib/drbd/notify-pri-on-incon-degr.sh;/usr/lib/drbd/notify-emergency-reboot.sh; echo b > /proc/sysrq-trigger ;reboot -f";
pri-lost-after-sb "/usr/lib/drbd/notify-pri-lost-after-sb.sh;/usr/lib/drbd/notify-emergency-reboot.sh; echo b > /proc/sysrq-trigger ;reboot -f";
local-io-error"/usr/lib/drbd/notify-io-error.sh;/usr/lib/drbd/notify-emergency-shutdown.sh; echo o > /proc/sysrq-trigger ;halt -f";

#before-resync-target "/usr/lib/drbd/snapshot-resync-target-lvm.sh -p 15 ---c 16k";
#after-resync-target /usr/lib/drbd/unsnapshot-resync-target-lvm.sh;
}
startup {
#wfc-timeout120;
#degr-wfc-timeout 120;
}
disk {
on-io-errordetach; #如果磁盘故障就拆掉，不让磁盘继续同步
#fencingresource-only;
}
net {
cram-hmac-alg"sha1"; #同步的算法
shared-secret"mydrbdlab"; #同步的随机码
}
syncer {
rate200M; #设置同步的速率
}
}定义一个资源，文件结尾必须是res
[root@node1 ~]# vim /etc/drbd.d/mystore.res #文件名最好和资源一致。
resource mystore {
onnode1.xmfb.com {
device /dev/drbd0; #资源名称
disk /dev/sda3; #本地drbd设备
address 172.16.4.100:7789; #drbd节点设置，而且需要保证可以解析对方的节点
meta-diskinternal; #drbd网络设置
}
onnode2.xmfb.com {
device /dev/drbd0;
disk /dev/sda3;
address 172.16.4.101:7789;
meta-diskinternal;
}
}以上文件在两个节点上必须相同，因此，可以基于ssh将刚才配置的文件全部同步至另外一个节点。
[root@node1 ~]# scp-r /etc/drbd.* node2:/etc/ drbd.conf 100% 133 0.1KB/s 00:00 mystore.res 100% 201 0.2KB/s 00:00 global_common.conf 100%2197 2.2KB/s 00:00
初始化资源，两个节点都运行
[root@node1 ~]# drbdadm create-md mystore initializing activity log NOT initializing bitmap Writing meta data... New drbd meta data block successfully created. [root@node2 ~]# drbdadm create-md mystore initializing activity log NOT initializing bitmap Writing meta data... New drbd meta data block successfully created.
启动drbd
[root@node1 ~]# service drbd start [root@node2 ~]# service drbd start
说明，第一个节点启动的时候会等待第二个节点启动，如果第二个节点不启动那么第一个节点也无法启动
drbd作为集群资源需要设置开机不启动
[root@node1 ~]# chkconfig drbd off [root@node1 ~]# chkconfig --list drbd drbd 0:off 1:off 2:off 3:off 4:off 5:off 6:off
启动后的配置
查看状态，由于都没有配置主节点所以都是从节点
[root@node1 ~]# cat /proc/drbd version: 8.4.5 (api:1/proto:86-101) GIT-hash: 1d360bde0e095d495786eaeb2a1ac76888e4db96build by [email protected], 2015-01-02 12:06:20 0:cs:Connected ro:Secondary/Secondaryds:Inconsistent/Inconsistent C r----- ns:0 nr:0dw:0 dr:0 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:5252056
设置主从
[root@node1 ~]# drbdadm -- --overwrite-data-of-peerprimary mystore [root@node1 ~]# cat /proc/drbd version: 8.4.5 (api:1/proto:86-101) GIT-hash: 1d360bde0e095d495786eaeb2a1ac76888e4db96build by [email protected], 2015-01-02 12:06:20 0:cs:SyncSource ro:Primary/Secondary ds:UpToDate/Inconsistent C r---n- ns:160720nr:0 dw:0 dr:164648 al:0 bm:0 lo:0 pe:9 ua:5 ap:0 ep:1 wo:f oos:5093336 [>....................]sync‘ed: 3.2% (4972/5128)M finish:0:02:40 speed: 31,744 (31,744) K/sec
主从已经设置完成，正在同步数据
格式化挂载drbd设备
[root@node1 ~]# mkfs.ext4 -j /dev/drbd0 [root@node1 ~]# mkdir /mydata [root@node1 ~]# mount /dev/drbd0 /mydata/
drbd复制验证
在主节点的drbd分区创建一个测试文件
[root@node1 ~]# cd /mydata/ [root@node1 mydata]# touch test [root@node1 mydata]# ls lost+found test
调换主从角色，调换之前需要卸载文件系统，因为主从节点不能同时使用
[root@node1 ~]# umount /mydata/ [root@node1 ~]# drbdadm secondary mystore [root@node1 ~]# drbd-overview 0:mystore/0 Connected Secondary/Secondary UpToDate/UpToDate
从节点挂载查看主节点创建的文件还在说明drbd配置成功
[root@node2 ~]# drbd-overview 0:drbd/0 ConnectedSecondary/Secondary UpToDate/UpToDate C r----- [root@node2 ~]# drbdadm primary mystore [root@node2 ~]# mkdir /mydata [root@node2 ~]# mount /dev/drbd0 /mydata [root@node2 ~]# cd /mydata [root@node2 mydata]# ls lost+found testdrbd
配置corosync+drbd高可用
配置之前需要先关闭drbd
[root@node1 ~]# service drbd stop [root@node2 ~]# service drbd stop
使用corosync定义drbd高可用是由linbit实现的
crm(live)ra# classes lsb ocf / heartbeat linbit pacemaker service stonith crm(live)ra# info ocf:linbit:drbd #查看drbd帮助信息
定义drbd资源和克隆
crm(live)configure# primitive mystorocf:linbit:drbd params drbd_resource="mystore" op monitorrole="Master" interval=10s timeout=20s op monitorrole="Slave" interval=20s timeout=20s op start timeout=240s op stoptimeout=100s crm(live)configure# ms my_mystor mystor metaclone-max="2" clone-node-max="1" master-max="1"master-node-max="1" notify="true"
定义drbd挂载
crm(live)configure# primitive mydataocf:heartbeat:Filesystem params device="/dev/drbd0"directory="/mydata" fstype="ext4" op monitor interval=20stimeout=40s op start timeout=60s op stop timeout=60s
设置位置约束
crm(live)configure# colocationmydata_with_ms_mystor_master inf: mydata my_mystor:Master
顺序约束
crm(live)configure#order mydata_after_ms_mystor_master Mandatory: my_mystor:promote mydata:start
转换测试
