实验要求
1、 部署mogilefs分布式文件系统
2、 nginx代理
实验环境
1、拓扑
2、网络地址规划
node1:172.16.76.10 nginx （centos6.8）
node2:172.16.76.20 Trackers 、storage Node （centos7.2）
node3:172.16.76.30 storage Node （centos7.2）
node4:172.16.76.40 storage Node (Mariadb) （centos7.2）
实验准备
同步时间、关闭iptables、selinux等。同时自己配置/etc/hots
基本配置
node1
1、nginx配置
a、解决依赖关系
# yum groupinstall "DevelopmentTools" "Server Platform Deveopment"
# yum install openssl-devel pcre-devel
b、安装
首先添加用户nginx，实现以之运行nginx服务进程：
# groupadd -r nginx
# useradd -r -g nginx nginx
c、开始编译和安装：
[[email protected] ~]# tar -xvfnginx-1.10.3.tar.gz [[email protected] ~]# tar -xvfnginx_mogilefs_module-1.0.4.tar.gz [[email protected] ~]# cd nginx-1.10.3/ [[email protected] 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 --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx/nginx.pid --lock-path=/var/lock/nginx.lock --user=nginx --group=nginx --with-http_ssl_module --with-http_flv_module --with-http_stub_status_module --with-http_gzip_static_module --http-client-body-temp-path=/var/tmp/nginx/client/ --http-proxy-temp-path=/var/tmp/nginx/proxy/ --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi --http-scgi-temp-path=/var/tmp/nginx/scgi --with-pcre --with-debug --add-module=/root/nginx_mogilefs_module-1.0.4/ [[email protected] nginx-1.10.3]# make &&make install [[email protected] ~]#vim /etc/rc.d/init.d/nginx #脚本内容见文章后附件。 [[email protected] ~]#chmod +x /etc/rc.d/init.d/nginx [[email protected] ~]#chkconfig –add nginx [[email protected]ode1 ~]#service nginx start
node1为centos6
node2
[[email protected] ~]# ls mogilefs/
MogileFS-Server-2.46-2.el6.noarch.rpm MogileFS-Utils-2.19-1.el6.noarch.rpm perl-Danga-Socket-1.61-1.el6.rf.noarch.rpm
MogileFS-Server-mogilefsd-2.46-2.el6.noarch.rpm Perlbal-1.78-1.el6.noarch.rpm perl-MogileFS-Client-1.14-1.el6.noarch.rpm
MogileFS-Server-mogstored-2.46-2.el6.noarch.rpm Perlbal-doc-1.78-1.el6.noarch.rpm perl-Perlbal-1.78-1.el6.noarch.rpm
[[email protected] ~]# for i in {2,3,4} ;do scp -r mogilefs node$i:/root/;done
#将mogilefs拷贝至其余各节点
[[email protected] ~]# for i in {2,3,4};do sshnode$i ‘yum install perl-Net-Netmask perl-IO-stringy perl-Sys-Syslogperl-IO-AIO -y‘;done #各节点安装
[[email protected] ~]# for i in {2,3,4};do sshnode$i ‘yum install ./mogilefs/*.rpm -y‘;done #各节点安装
node4:
[[email protected] ~]# yum install mariadb-server –y
2、初始化数据
a、数据库授权
[[email protected] ~]#vim /etc/my.cnf
skip_name_resolve=ON
innodb_file_per_table=ON
[[email protected] ~]# systemctl start mariadb
[[email protected] ~]# mysql
MariaDB [mogilefs]> grant all ON *.* [email protected]‘172.16.%.%‘ identified by ‘mogilepass‘
MariaDB [mogilefs]> GRANT ALL PRIVILEGES ON mogilefs.*TO [email protected]‘172.16.%.%‘ IDENTIFIED BY ‘mogile’ WITH GRANT OPTION;
MariaDB [mogilefs]> flush privileges;
b、初始化数据
[[email protected] ~]# mogdbsetup --dbhost=172.16.76.40 --dbname=mogilefs--dbrootuser=mogilefs -- dbrootpass=mogilefs --dbuser=mogile --dbpass=mogile --yes
3、设定连接数据库
[[email protected] ~]# vim /etc/mogilefs/mogilefsd.conf
db_dsn =DBI:mysql:mogilefs:host=172.16.76.40
db_user = mogile
db_pass =mogile
# IP:PORT tolisten on for mogilefs client requests
listen = 0.0.0.0:7001
[[email protected]~]# service mogilefsd start
存储节点配置
node2
[[email protected] ~]# vim/etc/mogilefs/mogstored.conf
maxconns = 10000
httplisten = 0.0.0.0:7500
mgmtlisten = 0.0.0.0:7501
docroot = /apps/data/mogilefs
[[email protected] ~]#mkdir -pv/apps/data/mogilefs
[[email protected] ~]# chown -R mogilefs.mogilefs /apps/data/mogilefs/
启动服务报错
#此处是因为启动脚本问题
[[email protected] ~]# vim /etc/init.d/mogstored
图中红线标记处为添加内容，修改保存后再次启动服务正常
[[email protected] ~]# systemctl daemon-reload
文章后 会将修改后脚本上传为附件。
[[email protected] ~]# for i in {3,4}; do scp/etc/mogilefs/mogstored.conf node$i:/etc/mogilefs/;done
#将此文件传递到node3、node4节点（配置相同）
[[email protected] ~]#for i in {3,4}; do scp/etc/init.d/mogstored node$i:/etc/init.d/ ;done
#修改后的启动脚本
[[email protected] ~]# for i in {3.4}; do sshnode$i ‘mkdir -pv /apps/data/mogilefs‘ ;done
#node3、node4节点创建存储目录
[[email protected]~]# for i in {3,4}; do ssh node$i ‘chown -R mogilefs.mogilefs /apps/data/mogilefs/‘ ;done#权限
[[email protected]~]# for i in {3,4}; do ssh node$i ‘systemctl daemon-reload‘ ;done
[[email protected]~]# for i in {3,4}; do ssh node$i ‘ service mogstored start‘ ;done
#启动各节点 mostored服务。
添加存储节点主机
[[email protected] ~]# mogadm host add172.16.76.20 --ip=172.16.76.20 --port=7500 --status=alive
[[email protected] ~]# mogadm host add172.16.76.30 --ip=172.16.76.30 --port=7500 --status=alive
[[email protected] ~]# mogadm host add172.16.76.40 --ip=172.16.76.40 --port=7500 --status=alive
添加存储设备
node2:
[[email protected] ~]# cd /apps/data/mogilefs/
[[email protected] mogilefs]# mkdir dev1
[[email protected] mogilefs]# chown -R mogilefs.mogilefs /apps/data/mogilefs/
node3
[[email protected] ~]# cd /apps/data/mogilefs/
[[email protected] mogilefs]# mkdir dev2
[[email protected] mogilefs]# chown -R mogilefs.mogilefs /apps/data/mogilefs/
node4
[[email protected] ~]# cd /apps/data/mogilefs/
[[email protected] mogilefs]# mkdir dev3
[[email protected] mogilefs]# chown -R mogilefs.mogilefs /apps/data/mogilefs/
node2:
[[email protected] ~]# mogadm device add172.16.76.20 1
[[email protected] ~]# mogadm device add172.16.76.30 2
[[email protected] ~]# mogadm device add172.16.76.40 3
域（名称空间）、类添加
添加域
node2
[[email protected]~]# mogadm domain add file #添加域 file
[[email protected] ~]#mogadm domain add imgs #添加域imgs
[[email protected] ~]#mogadm domain list #域列表
添加类
node2
[[email protected]~]# mogadm class add imgs jpg --hashtype=MD5 --mindevcount=2
#添加类jpg ，MD5算法最小文件分数为2
[[email protected] ~]#mogadm class add imgs png --hashtype=MD5 --mindevcount=2
[[email protected] ~]#mogadm class list #类列表
测试存储
上传文件
[[email protected]~]# mogupload --trackers=172.16.76.20:7001 --domain=imgs--class=jpg --key=‘/default.jpg‘ --file=‘/root/test.jpg‘
[[email protected]~]# mogupload --trackers=172.16.76.20 --domain=file --key=‘t1.html‘--file=‘/root/anaconda-ks.cfg‘
查询文件
[[email protected] ~]# mogfileinfo--trackers=172.16.76.20:7001 --domain=imgs --key=‘default.jpg‘
#注意此处显示devcount这是有问题，文章最后有说明
查看详细信息
[[email protected]~]# mogfiledebug --trackers=172.16.76.20:7001 --domain=imgs --key=‘default.jpg‘
浏览器测试查看
http://172.16.76.20:7500/dev1/0/000/000/0000000041.fid
此时说明mogilefs已经可以正常使用。
配置Nginx代理
[[email protected] ~]vim /etc/nginx/nginx.conf
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#access_log logs/access.log main;

mogilefs_methods get; #请求方法

}
expires 1h;
}
location /file/ {
mogilefs_tracker 172.16.76.20:7001;
mogilefs_domain file; #file域
mogilefs_methods get;
mogilefs_pass {
proxy_pass $mogilefs_path;
proxy_hide_headerContent-Type;
proxy_buffering off;
}
expires 1h;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
[[email protected] ~] nginx -t
nginx: the configuration file/etc/nginx/nginx.conf syntax is ok
nginx: configuration file/etc/nginx/nginx.conf test is successful
[[email protected] ~]nginx -s reload
测试
声明：本实验中存在两个问题
1、 由于nginx与mogilefs模块问题在centos7中安装存在问题，所以nginx代理节点安装在centos6.8 系统中。
2、mogilefs存储文件默认是2份，本实验中无法自动复制，文件始终是一份，
http://www.tuicool.com/articles/BbMJZfR此文中记录有解决方法，不过笔者按其方法实验并未成功，望各位见谅。如果那天问题解决我会更新此博客。当然若哪位能够解决此问题，希望给兄弟指点下，在这先谢谢了。
