heartbeat 3.0.4-drbd 8.9-Mysql 5.6--雙機(jī)互備高可用部署

發(fā)布時(shí)間：2020-08-11 22:43:44 來(lái)源：ITPUB博客 閱讀：261 作者：清風(fēng)艾艾 欄目：MySQL數(shù)據(jù)庫(kù)

   heartbeat 3.0.4-drbd 8.9-MySQL 5.6協(xié)同工作原理：首先，heartbeat作為高可用的控制角色，負(fù)責(zé)drbd存儲(chǔ)服務(wù)目錄的掛載（這里，drbd的啟動(dòng)個(gè)人理解是隨主機(jī)啟動(dòng)自動(dòng)

啟動(dòng)的，其作用就是將主節(jié)點(diǎn)本地的一塊盤(pán)與對(duì)端備節(jié)點(diǎn)的一塊盤(pán)做數(shù)據(jù)同步、保證兩端主機(jī)drbd相關(guān)的數(shù)據(jù)盤(pán)中數(shù)據(jù)完全一致），drbd的存儲(chǔ)目錄只在主節(jié)點(diǎn)掛載、接受讀

寫(xiě)，而備機(jī)保持不可用；當(dāng)heartbeat完成drbd存儲(chǔ)目錄掛載后，啟動(dòng)mysql數(shù)據(jù)庫(kù)，同時(shí)heartbeat負(fù)責(zé)檢測(cè)drbd存儲(chǔ)、mysql服務(wù)的狀態(tài)，當(dāng)服務(wù)異常，通過(guò)超時(shí)機(jī)制將資源

在備機(jī)啟動(dòng)，從而達(dá)到mysql雙機(jī)互備高可用的目的。

    前提條件：

    按照博文linux-ha heartbeat高可用的安裝配置（http服務(wù)高可用）完成heartbeat的安裝配置

    按照博文MySQL 5.6 for REHL 6.4編譯安裝完成mysql的安裝配置

5、將drbd加入內(nèi)核并設(shè)置drbd開(kāi)機(jī)自啟動(dòng)
[root@arbiter ~]# lsmod |grep drbd
[root@arbiter ~]# modprobe drbd
[root@arbiter ~]# lsmod |grep drbd

[root@mymongo1 ~]# echo "modprobe drbd>/dev/null 2>&1">/etc/sysconfig/modules/drbd.modules
[root@mymongo1 ~]#

6、編輯2個(gè)節(jié)點(diǎn)的drbd控制文件
[root@mymongo1 ~]# drbdadm create-md data

[root@mymongo1 ~]#

7、初始化兩個(gè)節(jié)點(diǎn)drbd源數(shù)據(jù)
[root@mymongo1 ~]# drbdadm create-md data
initializing activity log
NOT initializing bitmap
Writing meta data...

[root@mymongo1 ~]#
[root@arbiter ~]# drbdadm create-md data

[root@arbiter ~]#

8、啟動(dòng)并查看drbd
[root@mymongo1 ~]# drbdadm up data
[root@mymongo1 ~]# cat /proc/drbd

9、設(shè)置drbd角色，這里設(shè)置mymongo1為主節(jié)點(diǎn)
[root@mymongo1 ~]# drbdadm -- --overwrite-data-of-peer primary data
[root@mymongo1 ~]# cat /proc/drbd

10、2端機(jī)器創(chuàng)建相同的掛載點(diǎn)
[root@mymongo1 /]# mkdir data
[root@mymongo1 /]#

[root@arbiter /]# mkdir data
[root@arbiter /]#

11、格式化drbd0設(shè)備（只在主節(jié)點(diǎn)）
[root@mymongo1 /]# mkfs.ext4 -b 4096 /dev/drbd0

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/application/mysql/bin/mysqladmin -u root password 'new-password'
/application/mysql/bin/mysqladmin -u root -h 192.168.144.132 password 'new-password'

Alternatively you can run:

/application/mysql/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

cd . ; /application/mysql/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

cd mysql-test ; perl mysql-test-run.pl

Please report any problems at http://bugs.mysql.com/

WARNING: Found existing config file /application/mysql/my.cnf on the system.
Because this file might be in use, it was not replaced,
but was used in bootstrap (unless you used --defaults-file)
and when you later start the server.
The new default config file was created as /application/mysql/my-new.cnf,
please compare it with your file and take the changes you need.

WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
--defaults-file argument to mysqld_safe when starting the server
