We need to copy the three sample files and remove them.

[root@localhost fdfs]# cp client.conf.sample client.conf
[root@localhost fdfs]# cp storage.conf.sample storage.conf
[root@localhost fdfs]# cp tracker.conf.sample tracker.conf

FastDFS Installation Ended

Installation of Tracker

1. Create a tracker working directory

This directory is used to save tracker's data and log

[root@localhost fdfs]# mkdir /opt/fastdfs_tracker

2. Configure tracker

Configure tracker.conf in / etc/fdfs directory
The following four configurations are implemented:

1.disabled=false 
2.port=22122 #Default port number 
3.base_path=/opt/fastdfs_tracker #Directory I just created 
4.http.server_port=8080 #The default port is 8080
5.bind_addr= 0.0.0.0 Monitor address

The complete tracker.conf file information is as follows:

disabled=false

bind_addr= 0.0.0.0

port=22122

connect_timeout=30

network_timeout=60

base_path=/opt/fastdfs_tracker

Create Soft References after Modification and Save

[root@localhost fdfs]# ln -s /usr/bin/fdfs_storaged /usr/local/bin

4. Start tracker and add boot start item

[root@localhost fdfs]# service fdfs_trackerd start

Go through the tracker directory you just created and find that there are two more directories in the directory, data and log.

[root@localhost fdfs]# ll /opt/fastdfs_tracker/
//Total dosage 0
drwxr-xr-x. 2 root root 178 1 Month 1713:48 data
drwxr-xr-x. 2 root root  26 1 Month 1711:35 logs

Add tracker to startup entry

[root@localhost fdfs]# echo "service fdfs_trackerd start" |tee -a /etc/rc.d/rc.local

Take a look at tracker port listening

[root@localhost fdfs]# netstat -unltp|grep fdfs
tcp        0      0 0.0.0.0:22122           0.0.0.0:*               LISTEN      3088/fdfs_trackerd  

III. Installation of Storage

1. Configure the storage working directory

Because storage also requires a directory to store data, two more directories, fastdfs_storage_data and fastdfs_storage, have been built.

[root@localhost opt]# mkdir fastdfs_storage
[root@localhost opt]# mkdir fastdfs_storage_data
[root@localhost opt]# ll
//Total dosage 0
drwxr-xr-x. 4 root root 30 1 Month 1711:45 fastdfs_storage
drwxr-xr-x. 3 root root 18 1 Month 1711:45 fastdfs_storage_data
drwxr-xr-x. 4 root root 30 1 Month 1711:35 fastdfs_tracker

2. Configure storage file

Modify the storage.conf file in the / etc/fdfs directory
The main points of modification are as follows:

1.disabled=false 
2.group_name=group1 #Group name, change according to actual situation 
3.port=23000 #Set the storage port number, default is 23000. The storage port number of the same group must be the same. 
4.base_path=/opt/fastdfs_storage #Setting storage Data Files and Log Directories 
5.store_path_count=1 #Number of storage paths, need to match the number of store_path s 
6.store_path0=/opt/fastdfs_storage_data #Actual file storage path 
7.tracker_server=192.168.43.60:22122 #My ip address for CentOS7 
8.http.server_port=8888 #Setting the http port number

The complete information is as follows:

disabled=false
group_name=group1
bind_addr= 0.0.0.0
client_bind=true
port=23000
connect_timeout=30
network_timeout=60
heart_beat_interval=30

Create Soft References after Modification and Save

[root@localhost fdfs]#  ln -s /usr/bin/fdfs_storaged /usr/local/bin

3. Start Storage

[root@localhost fdfs]# service fdfs_storaged start

Set boot start:

[root@localhost fdfs]#  echo "service fdfs_storaged start" |tee -a /etc/rc.d/rc.local

Check to see if the service is started

[root@localhost fdfs]# netstat -unltp | grep fdfs 
tcp        0      0 0.0.0.0:22122           0.0.0.0:*               LISTEN      3088/fdfs_trackerd  
tcp        0      0 0.0.0.0:23000           0.0.0.0:*               LISTEN      3139/fdfs_storaged  

4. Verification Integration

At this point, everything for fastdfs has been installed. Finally, we need to make sure that storage is registered with tracker.
View commands:

[root@localhost fdfs]# /usr/bin/fdfs_monitor /etc/fdfs/storage.conf

After success, we can see that:
ip_addr = 192.168.43.60 (localhost.localdomain) ACTIVE

Four, test

1. Configuring Client

Modify client.conf file in / etc/fdfs/directory
The main points of modification are as follows:

base_path=/opt/fastdfs_tracker #tracker server file path
tracker_server=192.168.43.60:22122 #tracker server IP address and port number
http.tracker_server_port=8080 # The http port number of the tracker server must correspond to the settings of the tracker

The complete client.conf file information is as follows:

connect_timeout=30
network_timeout=60
base_path=/opt/fastdfs_tracker
tracker_server=192.168.43.60:22122
log_level=info
use_connection_pool = false
connection_pool_max_idle_time = 3600
load_fdfs_parameters_from_tracker=false
use_storage_id = false
storage_ids_filename = storage_ids.conf
http.tracker_server_port=8080

Analog upload
Upload a picture from the personal user directory for testing

[root@localhost fdfs]# fdfs_upload_file  /etc/fdfs/client.conf /home/zhangyongliang/9408.jpg  #The position of the picture is behind it.

When successful, the image storage path will be returned.

[root@localhost fdfs]# fdfs_upload_file  /etc/fdfs/client.conf /home/zhangyongliang/9408.jpg 
group1/M00/00/00/wKgrPFpe9OqAWsHxAAH5yvc2jn8251.jpg

Group name: group 1
Disk: M00
Catalogue: 00/00
File name: wKgrPFpe9OqAWsHxAAH5yvc2jn8251.jpg
The location of the uploaded file is as follows:

[root@localhost fdfs]# ll /opt/fastdfs_storage_data/data/00/00/
//Total dosage 256
-rw-r--r--. 1 root root 129482 1 Month 1715:02 wKgrPFpe9OqAWsHxAAH5yvc2jn8251.jpg
-rw-r--r--. 1 root root 129482 1 Month 1711:53 wKgrPFpeyM2ATkGUAAH5yvc2jn8013.jpg

There are created multi-level directories in the actual file storage path. There are 256 1-level directories under data, and 256 2-level subdirectories under each level, totaling 65536 files. Newly written files are routed to one of these subdirectories in hash mode, and then the file data is stored directly as a local file in the directory.

If we want to access the newly uploaded image, we need to combine nginx to achieve it.

5. Install Nginx and implement configuration

1. Install Nginx dependency environment

[root@localhost fdfs]# yum -y install pcre pcre-devel  
[root@localhost fdfs]# yum -y install zlib zlib-devel  
[root@localhost fdfs]# yum -y install openssl openssl-devel

2. Install nginx and add fastdfs-nginx-module

Unzip nginx and fastdfs-nginx-module

[root@localhost fdfs]# tar -zxvf nginx-1.10.3.tar.gz
[root@localhost fdfs]# unzip fastdfs-nginx-module-master.zip

After decompression, compile and install nginx in nginx directory, and add fastdfs-nginx-module

[root@localhost nginx-1.10.3]# ./configure --prefix=/usr/local/nginx --add-module=/home/zhangyongliang/apps/fastdfs-nginx-module-master/src #Location of fastdfs-nginx-module after decompression

Then compile and install

[root@localhost nginx-1.10.3]# make && make isntall

After successful installation, nginx will be installed in / usr/local/nginx. Check after installation

[root@localhost src]# ll /usr/local/nginx/
//Total dosage 8
drwx------. 2 nobody root    6 1 Month 1713:23 client_body_temp
drwxr-xr-x. 2 root   root 4096 1 Month 1713:17 conf
drwx------. 2 nobody root    6 1 Month 1713:23 fastcgi_temp
drwxr-xr-x. 2 root   root   40 1 Month 1713:17 html
drwxr-xr-x. 2 root   root   58 1 Month 1713:49 logs
-rw-r--r--. 1 root   root 1156 1 Month 1713:29 nginx.conf
drwx------. 2 nobody root    6 1 Month 1713:23 proxy_temp
drwxr-xr-x. 2 root   root   19 1 Month 1713:17 sbin
drwx------. 2 nobody root    6 1 Month 1713:23 scgi_temp
drwx------. 2 nobody root    6 1 Month 1713:23 uwsgi_temp

After successful installation, nginx is not running, and there are no temporary folders in the nginx folder, such as fastcgi_temp files.

3. Configure Storage Nginx

Modify the configuration file nginx.conf under the Nginx directory and add location information as follows:

server {
        listen       9991;
        server_name  localhost;

        location / {
            root   html;
            index  index.html index.htm;
        }

        location ~/group1/M00 {
            root /opt/fastdfs_storage/data;
            ngx_fastdfs_module;
        }

        location = /50x.html {
            root   html;
        }
}

Then enter the unzipped directory of FastDFS installation and copy http.conf and mime.types to / etc/fdfs directory:

[root@localhost src]# cp http.conf  mime.types  /etc/fdfs/
[root@localhost src]# cp mime.types  /etc/fdfs/

In addition, it is necessary to copy mod_fastdfs.conf in the src directory of the fastdfs-nginx-module installation directory to the / etc/fdfs directory:

[root@localhost src]# cp mod_fastdfs.conf  /etc/fdfs/

Modify the mod_fastdfs.conf file just copied:

base_path=/opt/fastdfs_storage  #Save Log Directory
tracker_server=192.168.43.60:22122 #IP address and port number of tracker server
storage_server_port=23000 #Port number of storage server
url_have_group_name = true #Does the group name exist in the file url?
store_path0=/opt/fastdfs_storage_data   #Storage path
group_count = 1 #Set the number of groups

At the end of the file, set the group

[group1]
group_name=group1
storage_server_port=23000
store_path_count=1
store_path0=/opt/fastdfs_storage_data

Create a symbolic connection from M00 to storage directory:

ln  -s  /opt/fastdfs_storage_data/data/ /opt/fastdfs_storage_data/data/M00

Start Nginx:

[root@localhost src]# /usr/local/nginx/sbin/nginx

Accessing Nginx to Start

[root@localhost src]# curl localhost:9991

4. Configure Tracker Nginx

Add a virtual machine to the nginx.conf file

upstream fdfs_group1 {
        server 127.0.0.1:9991;
    }
   server {
        listen       80;
        server_name  localhost;
       location /group1/M00 {
            proxy_pass http://fdfs_group1;
        }
