mogilefs简单入门
拓扑图安装mogilefs
本地安装的rpm包，下载地址http://down.iyunv.com/data/2290310
MogileFS-Server-2.46-2.el6.noarch.rpm
perl-Danga-Socket-1.61-1.el6.rf.noarch.rpm
MogileFS-Server-mogilefsd-2.46-2.el6.noarch.rpm
perl-MogileFS-Client-1.14-1.el6.noarch.rpm
MogileFS-Server-mogstored-2.46-2.el6.noarch.rpm
perl-Perlbal-1.78-1.el6.noarch.rpm
MogileFS-Utils-2.19-1.el6.noarch.rpm
这些安装包网上不多，并且这些安装包的依赖没有定义好，需要手动解决依赖，需要安装如下的安装包，这些包大多来自于epel源中
1
yum install perl-Net-Netmask perl-IO-stringy perl-Sys-Syslog perl-IO-AIO -y
准备工作
数据库授权

GRANT ALL PRIVILEGES ON *.* TO ‘mguser’@‘172.16.29.%’ IDENTIFIED BY ‘mgpass’;
grant all on *.* to 'root'@'172.16.29.%' identified by 'oldking';
FLUSH PRIVILEGES;
初始化数据库
1
mogdbsetup --dbhost=172.16.29.20 --dbname=mogilefs --dbrootpass=oldking --dbuser=mguser --dbpass=mgpass
tracker节点基本配置
vim /etc/mogilefs/mogilefsd.conf

#连接数据库的配置
db_dsn = DBI:mysql:mogilefs:host=172.16.29.20
db_user = mguser
db_pass = mgpass
#监听的端口
listen = 0.0.0.0:7001
conf_port = 7001
query_jobs = 10
delete_jobs = 1
replicate_jobs = 5
reaper_jobs = 1
启动tracker服务
1
service mogilefsd start
存储节点配置
vim /etc/mogilefs/mogstored.conf

maxconns = 10000
httplisten = 0.0.0.0:7500
mgmtlisten = 0.0.0.0:7501
#数据的目录
docroot = /data
启动storage服务
1
su - mogilefs -c "mogstored -c /etc/mogilefs/mogstored.conf --daemon"
集群管理
添加节点

mogadmhost add d1 --ip=172.16.29.10 --port=7500 --status=alive
mogadmhost add d2 --ip=172.16.29.2 --port=7500 --status=alive
mogadmhost add d3 --ip=172.16.29.20 --port=7500 --status=alive
mogadm host list #查看节点状态
添加设备

mogadmdevice add d1 1 #这里的1是和d1的/data/dev1目录对应的，这也意味着一个节点可以有多个设备
mogadmdevice add d2 2
mogadmdevice add d3 3
mogadmdevice list
两个存储节点提供磁盘

mkdir /data/dev1
chown mogilefs.mogilefs /data/dev1/
mkdir /data/dev2
chown mogilefs.mogilefs /data/dev2/
mkdir /data/dev3
chown mogilefs.mogilefs /data/dev3/
添加域

mogadm domain add files
mogadm domain add imgs
mogadm domain list
上传文件
1
mogupload --trackers=172.16.29.10 --domain=files --key='fstab.html' --file='/etc/fstab'
查询文件
1
mogfileinfo --trackers=172.16.29.10 --domain=files --key='fstab.html'
使用浏览器访问，这一行的信息取决去mogfileinfo
http://172.16.29.2:7500/dev2/0/000/000/0000000004.fid
删除指定文件
mogdelete--trackers=172.16.29.10--domain=<domain_name> --key=<key_name>
使用Nginx反向代理访问mogilefs内的文件
搭建这个服务器需要在centos6平台上，7上服务不能运行起来，拓扑图

下载模块文件并解压
wget http://nginx.org/download/nginx-1.10.3.tar.gz
wget http://www.grid.net.ru/nginx/download/nginx_mogilefs_module-1.0.4.tar.gz
tar xf nginx-1.10.3.tar.gz
tar xf nginx_mogilefs_module-1.0.4.tar.gz
安装开发包组合openssl和pcre
yum groupinstall "Development Tools" "Server Platform Deveopment" -y
yum install openssl-devel pcre-devel -y
添加Nginx组和用户
groupadd -r nginx
useradd -r -g nginx nginx
编译
cd nginx-1.10.3
./configure \
--prefix=/usr \
--sbin-path=/usr/sbin/nginx \
--conf-path=/etc/nginx/nginx.conf \
--error-log-path=/var/log/nginx/error.log \
