Mogilefs distributed storage-Installation notes

The environment is centos.

Er, it took a long time to install a plug-in because it had taken a lot of detours and thought it was dependent on too many baowhe modules.

Later I found that the installation can be simplified. Yum does not have mogilefs and can be installed through epel.

First, use epel

# Rpm-uvh

Http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-3.noarch.rpm

# Yum-y install mogilefsd Perl-mogilefs-client Perl-mogilefs-utils

# Yum-y install mogstored-backend-perlbal mogstored-backend-Lighttpd mogstored-backend-Apache Perl-mogilefs-client Perl-mogilefs-utils

If AIO cannot be found after an error is reported, you need to install AIO again.

# CPAN

# CPAN> install IO: AIO

The second installation method, using CPAN

# CPAN
# CPAN> install IO: AIO
# CPAN> install DBI
# CPAN> install DBD: MySQL

# CPAN> install mogilefs: Server
Install gearman: Client
Install gearman: Server
Install SYS: syscall
Install perlbal
Install net: Netmask
Install danga: Socket
Install gearman: Client: async

# CPAN> install mogilefs: utils
Install mogilefs: Client

The third method is the traditional method of installing dependent packages one by one:

This method is annoying, so I don't want to talk about it anymore. It's all tears. '''my hands have crated.

The configuration is as follows:

After figuring out the principle, it is quite easy to configure.

Step 1: Initialize the database
# Mogdbsetup -- dbhost = 127.0.0.1 -- dbname = mogilefs -- dbuser = mogilefs -- dbpass = jongin

Step 2: Create a tracker configuration file
# Vim/etc/mogilefsd. conf
Db_dsn DBI: mysql: mogilefs: 127.0.0.1
Db_user mogilefs
Db_pass jongin
Conf_port 6001
Listener_jobs 5

Step 3: Start trackers.

# Adduser mogile
# Su mogile
# Mogilefsd-C/etc/mogilefsd. conf -- daemon

Step 4: Initialize the storage server data

# Mogadm -- Lib =/usr/lib/perl5/5.8.8 -- trackers = 222.191.251.xx: 6001 host add mogilestorage -- IP = 222.191.251.xx -- Port = 7500 -- Status = alive
Check for effectiveness:
# Mogadm -- Lib =/usr/lib/perl5/5.8.8 -- trackers = 222.191.251.xx: 6001 host list
Add devices to storage server
# Mogadm-Lib =/usr/lib/perl5/5.8.8-trackers = 222.191.251.xx: 6001 device add mogilestorage 1
Check for effectiveness:
# Mogadm -- Lib =/usr/lib/perl5/5.8.8 -- trackers = 222.191.251.xx: 6001 Device List

Step 5: Create a storage configuration file
# Vim/Etc/mogstored. conf

Httplisten = 0.0.0.0: 7500
Mgmtlisten = 0.0.0.0: 7501
Docroot =/DATa/mdata

Create a storage directory-> mkdir-P/DATa/mdata/dev1

Step 6: Run mogilefs

# Mogstored-C/etc/mogstored. conf -- daemon

Check whether all your services are available
# Ps-Ef | grep mogilefsd
# Ps-Ef | grep mogstored

Part 7: Test and run

Generate domain
# Mogadm -- Lib =/usr/lib/perl5/5.8.8 -- trackers = 222.191.251.xx: 6001 domain add icv.cn
Add a class to domain
# Mogadm -- Lib =/usr/lib/perl5/5.8.8 -- trackers = 222.191.251.xx: 6001 class add icv.cn type1

1. Install the PHP-mogilefs Extension
Reference, http://projects.usrportage.de/index.fcgi/php-mogilefs

2. Write test files
<? PHP

$ Client-> connect ('19191.251.xxx, 222, 'jongin. com ');

$ Client-> put ('HTTP: // www.baidu.com/img/logo-yy.gif', 'myfile', 'type1 ');
$ Metadata = $ client-> get ('myfile ');
Print_r ($ metadata );
$ Content = file_get_contents ($ metadata ['pattern']);
Echo $ content;

?>
