Lamp architecture = LAMP refers to the first letters of Linux (operating system), Apache (HTTP server), MySQL (database software), and PHP (sometimes Perl or Python), generally used to build web servers.

Heartbeat + mysql + drbd

The three parts provide high availability, database, and storage services, respectively. Integrate the subsequent forums into a complete system

Description: server3,server4 provides the above three services

1 database

Direct yum install mysql-server-y # server3 and server4 both do

Mysql_secure_installation# security initialization, set the root password, otherwise the database can log in without a password

2.Heartbeat

[root@server3 heartbeat] # ls

Heartbeat-3.0.4-2.el6.x86_64.rpm heartbeat-libs-3.0.4-2.el6.x86_64.rpm

Heartbeat-devel-3.0.4-2.el6.x86_64.rpm ldirectord-3.9.5-3.1.x86_64.rpm

All Server3,server4 must be installed.

[root@server3 heartbeat] # yum install *-y

[root@server3 heartbeat] # cd / etc/ha.d/

[root@server3 ha.d] # ls

Harc rc.d README.config resource.d shellfuncs

[root@server3 ha.d] # vim haresources

Add at the end of the file:

Server3.example.com IPaddr::172.25.50.200/24/eth0 drbddisk::homework Filesystem::/dev/drbd2::/var/lib/mysql::ext4 mysqld

# # you can use server3.example.com IPaddr::172.25.50.200/24/eth0 mysqld for testing (the above is for drbd)

[root@server3 ha.d] # scp ha.cf haresources authkeys 172.25.50.40:/etc/ha.d/

Restart heartbeat on both sides

3.drbd shared memory

Assign a 4G virtual disk to both server3 and server4

[root@server3 mnt] # fdisk-l

Disk / dev/vdb: 4294 MB, 4294967296 bytes

16 heads, 63 sectors/track, 8322 cylinders

Units = cylinders of 1008 * 512 = 516096 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x00000000

[root@server4 drbd] # fdisk-l

Disk / dev/vda: 4294 MB, 4294967296 bytes

16 heads, 63 sectors/track, 8322 cylinders

Units = cylinders of 1008 * 512 = 516096 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x00000000

Install the following rpm packages

Drbd-8.4.2-2.el6.x86_64.rpm

Drbd-bash-completion-8.4.2-2.el6.x86_64.rpm

Drbd-heartbeat-8.4.2-2.el6.x86_64.rpm

Drbd-km-2.6.32_431.el6.x86_64-8.4.2-2.el6.x86_64.rpm

Drbd-pacemaker-8.4.2-2.el6.x86_64.rpm

Drbd-udev-8.4.2-2.el6.x86_64.rpm

Drbd-utils-8.4.2-2.el6.x86_64.rpm

Drbd-xen-8.4.2-2.el6.x86_64.rpm

[root@server3 drbd] # rpm-ivh *

Server4 also needs to install these rpm packages

[root@server3 mnt] # cd / etc/drbd.d/

[root@server3 drbd.d] # ls

Global_common.conf

[root@server3 drbd.d] # vim homework.res

[root@server3 drbd.d] # cat homework.res

Resource homework {

Meta-disk internal

Shared disk name customized by device / dev/drbd2;#

Syncer {verify-alg sha1

}

Hostname of on server3.example.com {# node

Disk / dev/vdb;# itself will be used to set the disk path to the share

Address 172.25.50.30 7789 Ten # Node ip

}

On server4.example.com {

Disk / dev/vda

Address 172.25.50.40:7789

}

}

In this way, you don't have to worry about how to solve the problem of publishing different names of shared disks.

[root@server3 drbd.d] # scp homework.res 172.25.50.40:/etc/drbd.d/

[root@server3 drbd.d] # drbdadm create-md homework

# # both server3 and server4

You can see the files created on server3 in the mounted directory, indicating that the distributed shared storage configuration is successful.

Heartbeat+mysql

Turn off the heartbeat service for two virtual machines

[root@server3 mnt] # / etc/init.d/mysqld stop

[root@server3 mnt] # drbdadm primary homework

[root@server3 mnt] # mount/ dev/drbd2 / mnt/mount/

[root@server3 mount] # cd / var/lib/mysql/

[root@server3 mysql] # cp-r * / mnt/mount/

[root@server3 ~] # umount / mnt/mount/

[root@server3 ~] # mount / dev/drbd2 / var/lib/mysql/

[root@server3] # chown mysql.mysql / var/lib/mysql/-R

[root@server3 ~] # / etc/init.d/mysqld start

Starting mysqld: [OK]

[root@server3 ~] # cd

[root@server3 ~] # / etc/init.d/mysqld stop

Stop mysqld: [OK]

[root@server3 ~] # umount / var/lib/mysql/

[root@server3 ~] # drbdadm secondary homework

Turning on the heartbeat service of server3,server4 will automatically open the service, when the heatbeat service of server3 is turned off. Vip:172.25.50.200 will be transferred to server4.

Finally:

Integration

Now let's build a forum.

[root@server1 mnt] # unzip Discuz_X3.2_SC_UTF8.zip-d / usr/local/nginx/html/

# # unzip this forum package in the default release directory of nginx

[root@server1 mnt] # cd / usr/local/nginx/html/

[root@server1 html] # ls

50x.html index.html nginx.php readme upload utility

[root@server1 html] # cd upload/

[root@server1 upload] # ls

Admin.php connect.php forum.php member.php search.php uc_server

Api cp.php group.php misc.php source userapp.php

Api.php crossdomain.xml home.php plugin.php static

Archiver data index.php portal.php template

Config favicon.ico install robots.txt uc_client

[root@server1 upload] # chmod 777 config/

[root@server1 upload] # chmod 777 data/-R

[root@server1 upload] # chmod 777 uc_*-R

Set the permissions that root users can log in remotely on serer3

Grant all privileges on *. * to "root" @ "%" identified by "redhat"

Query OK, 0 rows affected (0.00 sec)

Test method, remote login to 172.25.50.200 of the ip database on serer1

And have the permission to solve in the database.

On the browser: 172.25.50.10/upload/

Database write test: on server3

High availability tests:

Turn off the heartbeat service on server3.

As shown in the figure, you can see that after the heartbeat service is stopped, sererv4 automatically takes over the database, and the database content is the same as what you saw on server3!

The experiment was successful!
