注:存储节点服务器不用安装DBD::mysql模块
以上Perl模块也可到http://search.cpan.org/ 网站上下载安装，如安装Sys::Syscall模块。
# wget http://search.cpan.org/CPAN/authors/id/B/BR/BRADFITZ/Sys-Syscall-0.23.tar.gz
# tar zxvf Sys-Syscall-0.23.tar.gz
# cd Sys-Syscall-0.23
# perl Makefile.PL
# make
# make install
# wget http://search.cpan.org/CPAN/authors/id/D/DO/DORMANDO/MogileFS-Server-2.44.tar.gz
# tar zxvf MogileFS-Server-2.44.tar.gz
# cd MogileFS-Server-2.44
# perl Makefile.PL
# make
# make install
2.4、MogileFS Storage 存储节点安装
参考2.2、2.3。DBD::mysql 可不用安装
三、MogileFS 配置
3.1、mysql数据库设置
mysql> create database mogilefs;
mysql> grant all on mogilefs.* to 'mogile'@'%' identified '000000'
mysql> flush privileges;
3.2、创建mysql连接
# /usr/lib/mogdbsetup --dbhost=192.168.0.144 --dbname=mogilefs --dbuser=mogile --dbpassword=000000
3.3、创建Tracker配置文件
# vi /etc/mogliefs/mogilefsd.conf
内容如下：
db_dsn = DBI:mysql:mogilefs:host=192.168.0.144;port=3306;mysql_connect_timeout=5
db_user = mogile
db_pass = 000000
conf_port = 7001
listener_jobs = 5
node_timeout = 5
rebalance_ignore_missing = 1
3.4、MogileFS 启动与停止
由于mogilefs不能以root用户运行,创建mogile用户
# Useradd mogile –s /sbin/nologin
# su mogile –c “mogilefsd -c /etc/mogilefs/mogilefsd.conf --daemon”
使用pkill mogilefsd 来停止mogilefs 服务
3.5、MogileFS Storage 节点配置
创建Storage配置文件
vi /etc/mogilefs/mogstored.conf
内容如下:
httplisten=0.0.0.0:7500
mgmtlisten=0.0.0.0:7501
docroot=/data/mogdata
3.6、启动MogileFS Storage 节点
Mogstored –daemon
使用pkill mogstored 来停止mogstored 服务
四、管理配置MogileFS
4.1、添加Storeage节点到Tracker
# mogadm --trackers=192.168.0.11:7001 host add mog_store_22 --ip= 192.168.0.22 --port=7500 --status=alive
4.2、在存储节点中添加设备
# mogadm --trackers=192.168.0.11:7001 device add mog_store_22 101
在/data/mogdata/目录中创建dev201文件夹
4.3、在存储节点中使设备失效
# mogadm device mark mog_store_22 dev101 dead
4.4、添加域和类
添加image域
# mogadm domain add image
在image域中添加upload类 存储份数为 2
# mogadm class add image upload –mindevcount=2
4.5、查看域和tracker节点
# mogadm domain list
domain class mindevcount replpolicy
-------------------- -------------------- ------------- ---------------------------------------------------------
image default 2 MultipleHosts()
image upload 2 MultipleHosts()
# mogadm –trackers=192.168.0.11:7001 check
