1 Introduction
FastDFS is an open source lightweight distributed file system. It manages files. Its functions include: file storage, file synchronization, file access (file upload, file download) ), etc., solve the problems of large-capacity storage and load balancing. It is especially suitable for online services based on files, such as photo album websites, video websites, etc.
FastDFSThe server has two roles: tracker (tracker) and storage node (storage). The tracker mainly does scheduling work and plays a load balancing role in access.
Second installation
1, This installation uses three centos5.10 linux operating system
192.168.80.100 tracker Nginx ( Note that this machine does not install fastsfd-niginx Plug-in)
192.168.80.101 storage nginx
192.168.80.102 storage nginx
The installation of the operating system will not be discussed here.
2, Prepare the compilation environment yum -y install gcc gcc+ gcc-c++ openssl openssl-devel pcre pcre-devel Install all three machines, and create two new users fastdfs and nginx
useradd fastdfs -M -s /sbin/nologin useradd nginx -M -s /sbin/nologin
For the convenience of testing, please turn off the firewall service iptables stop
3, download the source code
type cd /usr/local/src/ Enter the directory, run the following command, download fastDFS 5.01
wget
Download nginx 1.7.0
wget http://nginx.org/download/nginx-1.7.0.tar.gz
Downloadfastdfs-nginx-module_v1.16
wget http://jaist.dl.sourceforge.net/project/fastdfs/FastDFS%20Nginx%20Module%20Source%20Code/fastdfs-nginx-module_v1.16.tar.gz
4. Install FastDFS (must be installed on all three machines)
tar
5, unzip
fastDFS-nginx-module[root@localhost ~]# cd /usr/local/src/
[root@localhost src]# tar xf fastdfs-nginx -module_v1.16
.tar.gz
6, InstallationNginx192.168.80.100 tarcker Machine installation
[root@localhost ~] # cd /usr/local /src/
[root@localhost src]# tar [root@localhost nginx-
1.7.0]# ./configure --user=

[root@localhost nginx-1.7.0]# make install
Three configurations
192.168.80.100 tracker configuration
1, create trackerdata and log storage directory
[root@localhost ~]# mkdir -p /data/fastdfs/tracker
2 , modify FastDFS’s tracker.conf configuration file
[root@localhost ~]# vim /etc/fdfs/tracker.conf
base_path=/data/fastdfs/tracker
max_c /span> kWork_thReads = 8
Store_Lookup = 0
Store_path = 0
ReserVED_SPACE_SPACE = 4g
//Run_by_group = Fastdfsrun_BY_USTER = FASTDFS
rotate_error_log=true
For configuration analysis, please refer to my article
trackerConfiguration file analysis
3, modify the configuration file of Nginx
[root@localhost ~]# vim /usr/local/nginx/conf/nginx.confuser
nginx
nginx;//Here are the already established users and groups worker_processes 3;
pid /usr/local/nginx/logs/nginx.pid;worker_rlimit_nofile
1024;
events {use epoll;
// epoll
is the pollLinuxkernel improved for handling large batches of file descriptorsworker_connections 1024 ;
} http {
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$re quest" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /usr/local/nginx/logs/access.log main;
upstream server_g1 {
server 192.168.
80.101:
80; //What is configured here is the IP of storagecan be configured with multiple units server 192.168.80 .
102:80;}server {
listen 80;
server_name localhost;
location /g1 {
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header
proxy_pass http://server_g1;
}
}
}
4, hand over tracker
toservice management and set up startup
[root@localhost ~]# cp / usr/local/ src/FastDFS/init.d/fdfs_trackerd /etc/init.d/[root@localhost ~]# chkconfig --add fdfs_trackerd
[root@localhost ~]# chkconfig fdfs_trackerd on
Configure storage
(Configure on192.168.80.101,102 respectively)
1, Create the data storage directory [root@localhost ~]# mkdir -p /data /fastdfs /storage
/data
2, modify the storage.conf
configuration file ofFastDFS
[root@localhost ~]# vim /etc/fdfs/storage.conf group_name=g1
base_path=/data/fastdfs
##The number of worker threads, usually set to CPU
numberwork_threads=8
store_ path_count=1
The address of store_path0=/data/fastdfs/storage
##tracker_server=192.168.
80.100:22122
##Run FastDFS
’s user grouprun_by_group =fastdfs
##User runningFastDFS
run_by_user=fastdfsfile_distribute_path_mode=1
rotate_error_log=true
3. Copy the configuration file of the nginx module to /etc/fdfs and modify it
[root@localhost ~]# cp /usr/local/src/fastdfs-nginx-module /src/mod_fastdfs.conf /etc/fdfs/
[root@localhost ~]# vim /etc/fdfs/mod_fastdfs.conf
c/span>
tracker_server=192.168. 80.100 :22122
group_name=g1
url_have_group_name = true
store_path_count=1
store_path0=/data/fastdfs/storage
4, modified nginx Configuration file
[root@localhost ~]# vim /usr/local/nginx/conf/nginx.conf
user nginxnginx;
worker_processes 8;
pid /usr/local/nginx/logs/nginx.pid;
worker_rlimit_nofile 1024;
events {
use epoll ;
worker_connections 1024 ;
}
http {
include mime.types;
default_type application/octet-stream;
log_format main '$ remote_addr - $remote_user [$time_local] " $request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /usr/local/nginx/logs/access.log main;
server {
listen 80;
server_name localhost;
location /g1/M00{
root /data/fastdfs/stor age/data;
ngx_fastdfs_module;
}
}
}
5, hand over storage [root@localhost ~]# cp /usr/local/src /FastDFS/init.d/fdfs_storaged /etc/init.d/
[root@localhost ~]# chkconfig --add fdfs_storaged
[root@localhost ~]# chkconfig fdfs_storaged on
[ root@localhost ~]# service fdfs_storaged startManage and set up startup for service
//Create a soft connection
[root@localhost ~]# ln -s /data/fastdfs/storage/ data /data/fastdfs/storage/data/M00
Four tests
1, start tracker, nginx on 192.168.80.100
[root@localhost ~]# service fdfs_trackerd start
[root@localhost ~]# /usr/local/nginx/sbin/nginx
2, start storage and ng respectively on 192.168.80.101,102 inx
[root@localhost ~]# service fdfs_storaged start
[root@localhost ~]# /usr/local/nginx/sbin/nginx
3 Configure a client in tracker Go to
[root@localhost ~]# vim /etc/fdfs/client.conf
base_path=/data/fastdfs
tracker_server=192.168.80.100:22122
4, view Cluster details
[root@localhost ~]# fdfs_monitor /etc/fdfs/client.conf
5, test upload
root@localhost ~]# fdfs_upload_file /etc/fdfs/ client.conf aa.jpg

The above introduces the installation and use of FastDFS+Nginx lightweight distributed file system, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
