接续接上篇 缓存时代来临 为蓝本,继续改造我们的百万级站点架构,这次我们
拿之前存储静态内容的 nfs 开刀,众所周知 nfs 的多台集群节点下可能由于多重
原因(磁盘io , 网络带宽, 并发场景),不适合做文件共享系统的基础结构.
互联网站点中,存在大量图片或其他静态内容,并且这些内容一般在1M之内,对于
海量小文件,我们将采用mogilefs分布式文件系统来完成.其中概念自行google.
# mogilefs分布式文件系统工作流程
架构已经愈发复杂,我们需要从新梳理一下.从下表中应该很容易看出第三弹的
任务,重新规划如下:
# 罗马数字表示在何阶段规划,(*)代表已废弃

# 新规划内容如下
操作过程
1. 安装配置阶段(slave3.king.com , slave4.king.com) # 准备如下包,因为我们要安装tracker节点和store节点 MogileFS-Server-2.46-2.el6.noarch.rpm MogileFS-Server-mogilefsd-2.46-2.el6.noarch.rpm MogileFS-Server-mogstored-2.46-2.el6.noarch.rpm MogileFS-Utils-2.19-1.el6.noarch.rpm perl-MogileFS-Client-1.14-1.el6.noarch.rpm perl-Net-Netmask-1.9015-8.el6.noarch.rpm perl-Perlbal-1.78-1.el6.noarch.rpm # # 安装mogilefs以及创建store目录,改变权限 yum -y install *.rpm perl-IO-AIO -y mkdir /dfs/mogdata/dev1 -pv (slace4上建dev2) chown -R mogilefs.mogilefs /var/run/mogilefsd /dfs/mogdata # # mysql -e 授权 建库(仅slave3执行) mysql -e "create database mogilefs;" mysql -e "grant all on *.* to 'root'@'172.16.%.%' identified by '';" mysql -e "grant all on mogilefs.* 'moguser'@'172.16.%.%' identified by 'mogpass';" mysql -e "flush privileges;" # # 初始化mogilefs所需数据库(仅slave3执行) mogdbsetup --dbhost=172.16.43.3 --dbport=3306 --dbname=mogilefs --dbuser=moguser --dbpass=mogpass --yes
# 接 1. 安装配置阶段(slave3.king.com , slave4.king.com) 操作 # mogilefs配置文件 vim /etc/mogilefs/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=172.16.43.3 db_user = moguser db_pass = mogpass # IP:PORT to listen on for mogilefs client requests listen = 172.16.43.3:7001 # Optional, if you don't define the port above. conf_port = 7001 # Number of query workers to start by default. query_jobs = 10 # Number of delete workers to start by default. delete_jobs = 1 # Number of replicate workers to start by default. replicate_jobs = 5 # Number of reaper workers to start by default. # (you don't usually need to increase this)# reaper_jobs = 1 # # store配置文件 vim /etc/mogilefs/mogstored.conf maxconns = 10000 httplisten = 0.0.0.0:7500 mgmtlisten = 0.0.0.0:7501 docroot = /dfs/mogdata # # 分别启动tracker以及store服务 (观察7001与7500,7501端口) service mogilefsd start service mogstored start
# 观察服务启动情况
2. 添加分布式文件系统(slave3.king.com) # 添加分布式节点信息 mogadm --tracker=172.16.43.3:7001 host add 172.16.43.3 --ip=172.16.43.3 --status=alive mogadm --tracker=172.16.43.4:7001 host add 172.16.43.4 --ip=172.16.43.4 --status=alive mogadm --tracker=172.16.43.3:7001 host list # # 添加分布式设备节点信息 mogadm --tracker=172.16.43.3:7001 device add 172.16.43.3 1 mogadm --tracker=172.16.43.4:7001 device add 172.16.43.4 2 mogadm --tracker=172.16.43.3:7001 device list # # 添加分布式域节点信息 mogadm --tracker=172.16.43.3:7001 domain add p_w_picpaths mogadm --tracker=172.16.43.3:7001 domain add text mogadm --tracker=172.16.43.3:7001 domain list
# mogilefs 所需 host , device , domain 添加准备就绪情况
3. ngxin反向代理解析文件
# 将第三方模块编译进nginx,先将之前的nginx服务停止,防止意外
service nginx stop
cd nginx-1.4.7
./configure --prefix=/usr/local/nginx --sbin-path=/usr/local/nginx/nginx --conf-path=/etc/nginx/nginx.conf --pid-path=/usr/local/nginx/nginx.pid --with-pcre --add-module=/root/mogilefs/nginx-mogilefs-module-master
make && make install
#
nginx-mogilefs-module-master.zip
#
http {
upstream mogcluster {
server 172.16.43.3:7001;
server 172.16.43.4:7001;
}
#
# 之前的系统图片设置到p_w_picpaths与imgs考虑程序一致性,这里
location /p_w_picpaths/ {
mogilefs_tracker mogcluster;
mogilefs_domain p_w_picpaths;
mogilefs_methods GET PUT DELETE;
mogilefs_pass {
proxy_pass $mogilefs_path;
proxy_hide_header Content-Type;
proxy_buffering off;
}
}
#
location /imgs/ {
mogilefs_tracker mogcluster;
mogilefs_domain p_w_picpaths;
mogilefs_methods GET PUT DELETE;
mogilefs_pass {
proxy_pass $mogilefs_path;
proxy_hide_header Content-Type;
proxy_buffering off;
}
}
#
# 之前系统静态文件分为html,css,js等目录,所以这里需要目录定位
location ~* ^(/(static|css|js)/.*)$ {
mogilefs_tracker mogcluster;
mogilefs_domain text;
mogilefs_pass $1 {
proxy_pass $mogilefs_path;
proxy_hide_header Content-Type;
proxy_buffering off;
}
}
}
4. 以上一篇架构为例,添加测试文件 mogupload --trackers=172.16.43.3:7001 --domain=p_w_picpaths --key='/2.jpg' --file='./imgs/2.jpg' mogupload --trackers=172.16.43.3:7001 --domain=p_w_picpaths --key='/1.jpg' --file='./p_w_picpaths/1.jpg' mogupload --trackers=172.16.43.3:7001 --domain=text --key='static/index.html' --file='./static/index.html' mogupload --trackers=172.16.43.3:7001 --domain=text --key='css/test.css' --file='./css/test.css' mogupload --trackers=172.16.43.3:7001 --domain=text --key='js/test.js' --file='./js/test.js'
# 测试
service nginx restart
service varnish restart
使用浏览器隐身模式访问
最后附完整slave3.king.com中nginx的配置文件
