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
slave1.king.com
172.16.43.1
DNS轮询 -> slave1.king.com , slave2.king.com(I)
haproxy七层代理流量分离 -> imgs , text , dynamic(I)
keepalived 为haproxy HA(I)
slave2.king.com
172.16.43.2
haproxy七层代理流量分离 -> imgs , text , dynamic(I)
keepalived 为haproxy HA(I)
slave3.king.com
172.16.43.3
nginx虚拟主机组 -> imgs1.king.com , imgs2.king.com
text1.king.com , text2.king.com

memcache session, key/value cache(II)
mogilefs tracker node(III) New!!
mogilefs store node(III) New!!
slave4.king.com
172.16.43.4
nginx虚拟主机 -> dynamic2.king.com(I)
php-fpm模块(I)
mysql-proxy(I)
mysql数据库(I)
varnish text 缓存(II)
memcache session, key/value cache(II)
mogilefs tracker node(III) New!!
mogilefs store node(III) New!!
# 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 images
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images与imgs考虑程序一致性,这里
location /images/ {
mogilefs_tracker mogcluster;
mogilefs_domain images;
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 images;
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 $mogilefs_path;
proxy_hide_header Content-Type;
proxy_buffering off;
}
}
}
4. 以上一篇架构为例,添加测试文件
mogupload --trackers=172.16.43.3:7001 --domain=images --key='/2.jpg' --file='./imgs/2.jpg'
mogupload --trackers=172.16.43.3:7001 --domain=images --key='/1.jpg' --file='./images/1.jpg'
mogupload --trackers=172.16.43.3:7001 --domain=text --key='static/index.html' --file='./static/index.html'
mogupload --trackers=172.16.43.3:7001 --domain=text --key='css/test.css' --file='./css/test.css'
mogupload --trackers=172.16.43.3:7001 --domain=text --key='js/test.js' --file='./js/test.js'
# 测试 service nginx restart
service varnish restart
使用浏览器隐身模式访问
最后附完整slave3.king.com中nginx的配置文件 #user nobody; worker_processes 1; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; #log_format main '$remote_addr - $remote_user [$time_local] "$request" ' # '$status $body_bytes_sent "$http_referer" ' # '"$http_user_agent" "$http_x_forwarded_for"'; #access_log logs/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 5; gzip on; upstream mogcluster { server 172.16.43.3:7001; server 172.16.43.4:7001; } server { listen 80; server_name dynamic1.king.com; access_log /var/log/nginx/dynamic1.access.log; location ~ .php$ { root /nfsshared/html; fastcgi_pass 172.16.43.3:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } location / { root /nfsshared/html; index index.php index.html index.htm; } } server { listen 80; server_name imgs1.king.com; access_log /var/log/nginx/imgs1.access.log; location /images/ { mogilefs_tracker mogcluster; mogilefs_domain images; 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 images; mogilefs_methods GET PUT DELETE; mogilefs_pass { proxy_pass $mogilefs_path; proxy_hide_header Content-Type; proxy_buffering off; } } error_page 404 /404.html; error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } server { listen 80; server_name imgs2.king.com; access_log /var/log/nginx/imgs2.access.log; location /images/ { mogilefs_tracker mogcluster; mogilefs_domain images; 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 images; mogilefs_methods GET PUT DELETE; mogilefs_pass { proxy_pass $mogilefs_path; proxy_hide_header Content-Type; proxy_buffering off; } } error_page 404 /404.html; error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } server { listen 80; server_name text1.king.com; access_log /var/log/nginx/text1.access.log; location ~* ^(/(static|css|js)/.*)$ { mogilefs_tracker mogcluster; mogilefs_domain text; mogilefs_pass $1 { proxy_pass $mogilefs_path; proxy_hide_header Content-Type; proxy_buffering off; } } location / { index index.html index.htm; } error_page 404 /404.html; error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } server { listen 80; server_name text2.king.com; access_log /var/log/nginx/text2.access.log; location ~* ^(/(static|css|js)/.*)$ { mogilefs_tracker mogcluster; mogilefs_domain text; mogilefs_pass $1 { proxy_pass $mogilefs_path; proxy_hide_header Content-Type; proxy_buffering off; } } location / { index index.html index.htm; } error_page 404 /404.html; error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } }
