nginx代理mogilefs集群实现
一、实验拓扑
二、实验环境
三、实验步骤
1.节点部署
192.168.0.3 node1 [Nginx,Tracker,Storage,Mariadb]
192.168.0.4 node2 [Tracker,Storage]
192.168.0.5 node3 [Tracker,Storage]
2.初始化工作
配置好三台服务器IP，hosts文件等网络环境，时间同步以及以下的rpm包安装
注：以下操作在三个节点都执行
#下载rpm包（附件有提供）
MogileFS-Server-2.46-2.el7.centos.noarch.rpm
MogileFS-Server-mogilefsd-2.46-2.el7.centos.noarch.rpm
MogileFS-Server-mogstored-2.46-2.el7.centos.noarch.rpm
MogileFS-Utils-2.19-1.el7.centos.noarch.rpm
perl-Danga-Socket-1.61-1.el6.rf.noarch.rpm
perl-MogileFS-Client-1.14-1.el7.centos.noarch.rpm
perl-Perlbal-1.78-1.el6.noarch.rpm
#安装依赖环境
yum install perl-Net-Netmask perl-IO-stringy perl-Sys-Syslog perl-IO-AIO -y
#安装rpm包
yum install *.rpm -y
3.node1节点部署mariadb，mogilefsd，mogstored
3.1.node1部署Mariadb
yum install mariadb-server -y
vim /etc/my.cnf.d/server.cnf
[mysqld]
skip_name_resolve=1
innodb_file_per_table = 1
#启动mariadb
systemctl start mariadb
#连接mysql，进行以下操作
mysql
GRANT ALL ON *.* TO ‘root‘@‘192.168.0.%‘ IDENTIFIED BY ‘rootpass‘;
GRANT ALL ON mogilefs.* TO ‘moguser‘@‘192.168.0.%‘ IDENTIFIED BY ‘moguserpass‘;
CREATE DATABASE mogilefs;
FLUSH PRIVILEGES;
quit
#设定mogilefs数据库，生成数据表
mogdbsetup --dbhost=192.168.0.3 --dbuser=moguser --dbpass=moguserpass --dbname=mogilefs --dbrootpass=rootpass
#连接mysql，查看数据库是否生成
mysql -u root -h192.168.0.3 -prootpass
MariaDB [(none)]> use mogilefs;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
MariaDB [mogilefs]> SHOW TABLES;

3.2node1配置mogilefsd
vim /etc/mogilefs/mogilefsd.conf
db_dsn = DBI:mysql:mogilefs:host=192.168.0.3
db_user = moguser
db_pass = moguserpass
listen = 0.0.0.0:7001
3.3启动mogilefsd
[[email protected] ~]# service mogilefsd start
Starting mogilefsd (via systemctl): [ OK ]
[[email protected] ~]# ss -tln
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 50 *:3306 *:*
LISTEN 0 128 *:22 *:*
LISTEN 0 128 *:7001 *:*
LISTEN 0 100 127.0.0.1:25 *:*
LISTEN 0 128 :::22 :::*
LISTEN 0 100 ::1:25 :::*
3.4配置storage（推荐所有节点都配置）
#创建存放文件的目录
mkdir /data/mogilefs/dev1 -pv
mkdir: created directory ‘/data’
mkdir: created directory ‘/data/mogilefs’
mkdir: created directory ‘/data/mogilefs/dev1’
vim /etc/mogilefs/mogstored.conf
maxconns = 10000
httplisten = 0.0.0.0:7500
mgmtlisten = 0.0.0.0:7501
docroot = /data/mogilefs/
#修改目录的权限
chown mogilefs.mogilefs /data/mogilefs/ -R
#启动mogstored
[[email protected] ~]# service mogstored start
Starting mogstored (via systemctl): [ OK ]
4.node2、node3节点部署mogstored操作
4.1node2操作
[[email protected] ~]# mkdir /data/mogilefs/dev2 -pv
mkdir: created directory ‘/data’
mkdir: created directory ‘/data/mogilefs’
mkdir: created directory ‘/data/mogilefs/dev2’
vim /etc/mogilefs/mogstored.conf
maxconns = 10000
httplisten = 0.0.0.0:7500
mgmtlisten = 0.0.0.0:7501
docroot = /data/mogilefs/
#修改目录的权限
chown mogilefs.mogilefs /data/mogilefs/ -R
#启动mogstored
[[email protected] ~]# service mogstored start
Starting mogstored (via systemctl): [ OK ]
4.2node3操作
[[email protected] ~]# mkdir /data/mogilefs/dev3 -pv
mkdir: created directory ‘/data’
mkdir: created directory ‘/data/mogilefs’
mkdir: created directory ‘/data/mogilefs/dev3’
vim /etc/mogilefs/mogstored.conf
maxconns = 10000
httplisten = 0.0.0.0:7500
mgmtlisten = 0.0.0.0:7501
docroot = /data/mogilefs
#修改目录的权限
chown mogilefs.mogilefs /data/mogilefs/ -R
#启动mogstored
[[email protected] ~]# service mogstored start
Starting mogstored (via systemctl): [ OK ]
5.node1配置操作
5.1.配置mogilefsd
#添加主机

6.上传文件/图片测试
#在linu主机中找几张图片
find / -name "*.jpg" -exec cp {} /tmp/ \;
#上传图片（图片格式写错了，囧）
mogupload --tracker=192.168.0.3:7001 --domain=images --key=‘1.gpg‘ --file=‘/tmp/morning.jpg‘ --class=jpeg
#上传图片
mogupload --tracker=192.168.0.3:7001 --domain=images --key=‘1.jpg‘ --file=‘/tmp/day.jpg‘ --class=jpeg
#查看图片的信息
[[email protected] tmp]# mogfileinfo --tracker=192.168.0.3:7001 --domain=images --key=‘1.jpg‘
- file: 1.jpg
class: jpeg
devcount: 1
domain: images
fid: 3
key: 1.jpg
length: 961243
- http://192.168.0.3:7500/dev1/0/000/000/0000000003.fid
[[email protected] tmp]# mogfileinfo --tracker=192.168.0.3:7001 --domain=images --key=‘1.gpg‘
- file: 1.gpg

#上传文件
mogupload --trackers=192.168.0.3 --domain=files --key=‘/fstab.txt‘ --file=/etc/fstab
#查看文件
[[email protected] tmp]# mogfileinfo --trackers=192.168.0.3 --domain=files --key=‘/fstab.txt‘
- file: /fstab.txt
class: default

#访问测试(在浏览器中输入)
http://192.168.0.3:7500/dev1/0/000/000/0000000003.fid
http://192.168.0.5:7500/dev3/0/000/000/0000000002.fid
(ps：可以看出，访问的地址实在反人类，其实我们可以通过加入其他的模块解决这种办法，在下面会介绍这个模块）
#删除文件
mogdelete --tracker=192.168.0.3:7001 --domain=images --key=‘1.jpg‘
mogdelete --tracker=192.168.0.3:7001 --domain=images --key=‘1.gpg‘
mogdelete --tracker=192.168.0.3:7001 --domain=files --key=‘/fstab.txt‘
7.配置nginx
nginx 的mogilefs模块的官方文档地址：http://www.grid.net.ru/nginx/mogilefs.en.html
#下载nginx_mogilefs模块
wget http://www.grid.net.ru/nginx/download/nginx_mogilefs_module-1.0.4.tar.gz
tar xvf nginx_mogilefs_module-1.0.4.tar.gz
mv nginx_mogilefs_module-1.0.4 /usr/local/ cd /usr/local/src
wget
#安装nginx依赖环境包
yum install -y gcc pcre pcre-devel zlib zlib-devel openssl openssl-devel
useradd -r nginx
tar xvf nginx-1.10.3.tar.gz
cd nginx-1.10.3
#编译安装
./configure --with-pcre --user=nginx --group=nginx --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_realip_module --add-module=/usr/local/nginx_mogilefs_module-1.0.4
make && make install
#编译之后出现报错
make[1]: *** [objs/addon/nginx_mogilefs_module-1.0.4/ngx_http_mogilefs_module.o] Error 1
make[1]: Leaving directory `/usr/local/src/nginx-1.10.3‘
make: *** [build] Error 2
解决办法:
vim objs/Makefile
#把-Werror删除掉
#再次安装，成功
make && make install
#配置nginx环境变量
vi /etc/profile.d/nginx.sh
export PATH="$PATH:/usr/local/nginx/sbin"
#重新加载
. /etc/profile.d/nginx.sh
#查看环境变量
[[email protected] ~]# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/nginx/sbin
#接下来，编辑nginx配置文件
cd /usr/local/nginx/conf/
vi nginx.conf
#加入的配置段
upstream trackers {
server 192.168.0.3:7001 weight=1;
server 192.168.0.4:7001 weight=1;
server 192.168.0.5:7001 weight=1;
check interval=1000 rise=2 fall=5 timeout=1000;
}
location /images/ {
mogilefs_tracker trackers;
mogilefs_domain images;
mogilefs_methods GET;
mogilefs_noverify on;
mogilefs_pass {
proxy_pass $mogilefs_path;
proxy_hide_header Content-type;
proxy_buffering off;
}
}
#检查并启动nginx
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[[email protected] conf]# nginx
#上传图片
mogupload --trackers=192.168.0.3 --domain=images --key=‘1.jpg‘ --file=‘/tmp/day.jpg‘ --class=jpeg
#浏览器访问测试
http://192.168.0.3/images/1.jpg
8.将三个节点都配置成tracker #将mogilefsd.conf文件拷贝到其他的节点 [[email protected] conf]# scp /etc/mogilefs/mogilefsd.conf node2:/etc/mogilefs/ mogilefsd.conf 100% 1465 1.4KB/s 00:00 [[email protected] conf]# scp /etc/mogilefs/mogilefsd.conf node3:/etc/mogilefs/ [email protected]‘s password: mogilefsd.conf 100% 1465 1.4KB/s 00:00 #启动node2、node3的mogilefsd [[email protected] ~]# service mogilefsd start Starting mogilefsd (via systemctl): [ OK ] [[email protected] ~]# service mogilefsd start Starting mogilefsd (via systemctl): [ OK ] #测试是否成为tracker [[email protected] conf]# moglistkeys --trackers=192.168.0.3:7001 --domain=images 1.jpg [[email protected] conf]# moglistkeys --trackers=192.168.0.4:7001 --domain=images 1.jpg [[email protected] conf]# moglistkeys --trackers=192.168.0.5:7001 --domain=images 1.jpg 三个节点都可以查看内容列表，由此证明三个节点都是tracker。
