Mogilefs杂记（1）

Mogilefs

Mogilefs搭建

环境

master1:nginx反代节点
master2、3、4：成为mogilefs节点
master2:MySQL节点

0、安装依赖环境包

[root@master2 ~]# yum install -y perl-Sys-Syslog perl-Net-Netmask perl-IO-AIO
[root@master3 ~]# yum install -y perl-Sys-Syslog perl-Net-Netmask perl-IO-AIO
[root@master4 ~]# yum install -y perl-Sys-Syslog perl-Net-Netmask perl-IO-AIO

yum install -y perl-core

1、mogilefs组件安装

[root@master2 mogilefs]# ls
MogileFS-Server-2.46-2.el6.noarch.rpm            MogileFS-Utils-2.19-1.el6.noarch.rpm        perl-MogileFS-Client-1.14-1.el6.noarch.rpm
MogileFS-Server-mogilefsd-2.46-2.el6.noarch.rpm  Perlbal-1.78-1.el6.noarch.rpm               perl-Perlbal-1.78-1.el6.noarch.rpm
MogileFS-Server-mogstored-2.46-2.el6.noarch.rpm  perl-Danga-Socket-1.61-1.el6.rf.noarch.rpm
[root@master3 mogilefs]# yum install -y *.rpm

3、4节点同上

2、master搭建mysql

2.1 MariaDB配置

[root@master2 ~]# vim /etc/my.cnf

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
innodb_file_per_table = 1
skip_name_resolve = 1

[root@master2 ~]# systemctl start mariadb.service

设置开机启动mariadb：
[root@master2 ~]# systemctl enable mariadb.service

2.2 mysql创建数据库和用户

创建远程连接的root用户：
MariaDB [(none)]> GRANT ALL ON *.* TO 'root'@'10.201.106.%' IDENTIFIED BY 'mageedu';

创建数据库：
MariaDB [(none)]> CREATE DATABASE mogilefs;

创建普通账号：
MariaDB [(none)]> GRANT ALL ON mogilefs.* TO 'moguser'@'10.201.106.%' IDENTIFIED BY 'mogpass';

MariaDB [(none)]> FLUSH PRIVILEGES;

2.3 使用mogdbsetup使数据初始化

[root@master2 ~]# mogdbsetup --dbhost=10.201.106.132 --dbrootpass='magedu' --dbuser='moguser' --dbpass='mogpass'

查看mogilefs数据库的表格
MariaDB [mogilefs]> SHOW TABLES;
+----------------------+

3、配置mogilefs

3.1 master2：tracker配置

[root@master2 mogilefs]# vim mogilefsd.conf

# Enable daemon mode to work in background and use syslog
daemonize = 1
# Where to store the pid of the daemon (must be the same in the init script)
pidfile = /var/run/mogilefsd/mogilefsd.pid
# Database connection information
db_dsn = DBI:mysql:mogilefs:host=10.201.106.132
db_user = moguser
db_pass = mogpass
# IP:PORT to listen on for mogilefs client requests
listen = 0.0.0.0:7001

echo
}

[root@master2 ~]# systemctl daemon-reload
[root@master2 ~]# service mogstored start

4.4 master3,4 storage配置

[root@master3 ~]# mkdir -pv /data/mogilefs/dev2
mkdir: created directory ‘/data’
mkdir: created directory ‘/data/mogilefs’
mkdir: created directory ‘/data/mogilefs/dev2’
[root@master3 ~]# chown -R mogilefs.mogilefs /data/mogilefs/

[root@master4 ~]# mkdir -pv /data/mogilefs/dev3
mkdir: created directory ‘/data’
mkdir: created directory ‘/data/mogilefs’
mkdir: created directory ‘/data/mogilefs/dev3’
[root@master4 ~]# chown -R mogilefs.mogilefs /data/mogilefs/

拷贝脚本：
[root@master2 mogilefs]# scp /etc/rc.d/init.d/mogstored master3:/etc/rc.d/init.d/
root@master3's password:
mogstored                                                             100% 1456     1.4KB/s   00:00

root@master4's password:
mogstored                                                             100% 1456     1.4KB/s   00:00
[root@master2 mogilefs]#

[root@master2 mogilefs]# scp /etc/mogilefs/mogstored.conf master3:/etc/mogilefs/
root@master3's password:
mogstored.conf                                                        100%   95     0.1KB/s   00:00
[root@master2 mogilefs]# scp /etc/mogilefs/mogstored.conf master4:/etc/mogilefs/

[root@master2 mogilefs]#

启动服务：
[root@master3 ~]# service mogstored start
Starting mogstored (via systemctl):                        [  OK  ]

[root@master4 ~]# service mogstored start
Starting mogstored (via systemctl):                        [  OK  ]

5、tracker节点添加storage节点

5.1 检查当前tracker节点信息

[root@master2 ~]# mogadm check
Checking trackers...
127.0.0.1:7001 ... OK

Checking hosts...
No devices found on tracker(s).

[root@master2 ~]# mogadm --trackers=10.201.106.132:7001 check
Checking trackers...
10.201.106.132:7001 ... OK

Checking hosts...
No devices found on tracker(s).

5.2 添加主机

[root@master2 ~]# mogadm --trackers=10.201.106.132:7001 host add 10.201.106.132 --ip=10.201.106.132 --status=alive
[root@master2 ~]# mogadm host list
10.201.106.132 [1]: alive
IP:       10.201.106.132:7500

添加另外两个节点：
[root@master2 ~]# mogadm --trackers=10.201.106.132:7001 host add 10.201.106.133 --ip=10.201.106.133 --status=alive
[root@master2 ~]#
[root@master2 ~]# mogadm --trackers=10.201.106.132:7001 host add 10.201.106.134 --ip=10.201.106.134 --status=alive
[root@master2 ~]# mogadm host list
10.201.106.132 [1]: alive
IP:       10.201.106.132:7500

10.201.106.133 [2]: alive
IP:       10.201.106.133:7500

10.201.106.134 [3]: alive
IP:       10.201.106.134:7500

[root@master2 ~]#

5.3 修改节点状态

[root@master2 ~]# mogadm host mark 10.201.106.133 down
[root@master2 ~]# mogadm host list
10.201.106.132 [1]: alive
IP:       10.201.106.132:7500

10.201.106.133 [2]: down
IP:       10.201.106.133:7500

10.201.106.134 [3]: alive
IP:       10.201.106.134:7500

[root@master2 ~]# mogadm host mark 10.201.106.133 alive
[root@master2 ~]# mogadm host list
10.201.106.132 [1]: alive
IP:       10.201.106.132:7500

10.201.106.133 [2]: alive
IP:       10.201.106.133:7500

10.201.106.134 [3]: alive
IP:       10.201.106.134:7500

[root@master2 ~]#

[root@master2 ~]#

7、创建管理域

7.1 创建管理域

[root@master2 ~]# mogadm domain add images
[root@master2 ~]# mogadm domain add file
[root@master2 ~]# mogadm domain list
domain               class                mindevcount   replpolicy   hashtype
-------------------- -------------------- ------------- ------------ -------
file                 default                   2        MultipleHosts() NONE

images               default                   2        MultipleHosts() NONE

[root@master2 ~]#

8 管理域中的类

8.1 查看class

[root@master2 ~]# mogadm class list
domain               class                mindevcount   replpolicy   hashtype
-------------------- -------------------- ------------- ------------ -------
file                 default                   2        MultipleHosts() NONE

images               default                   2        MultipleHosts() NONE

[root@master2 ~]#

8.2 在图片域中添加class

[root@master2 ~]# mogadm class add images jpeg
[root@master2 ~]# mogadm class add images png
[root@master2 ~]# mogadm class add images gif
[root@master2 ~]# mogadm class list
domain               class                mindevcount   replpolicy   hashtype
-------------------- -------------------- ------------- ------------ -------
file                 default                   2        MultipleHosts() NONE

images               default                   2        MultipleHosts() NONE
images               gif                       2        MultipleHosts() NONE
images               jpeg                      2        MultipleHosts() NONE
images               png                       2        MultipleHosts() NONE

[root@master2 ~]#

8.3 class限制，不要副本

[root@master2 ~]# mogadm class add file plaintext --mindevcount=1

[root@master2 ~]# mogadm class list
domain               class                mindevcount   replpolicy   hashtype
-------------------- -------------------- ------------- ------------ -------
file                 default                   2        MultipleHosts() NONE
file                 plaintext                 1        MultipleHosts() NONE

8.4 设置class至少3个保留副本

[root@master2 ~]# mogadm class add file html --replpolicy="MultipleHosts(3)"
[root@master2 ~]# mogadm class list
domain               class                mindevcount   replpolicy   hashtype
-------------------- -------------------- ------------- ------------ -------
file                 default                   2        MultipleHosts() NONE
file                 html                      2        MultipleHosts(3) NONE
