firewall- cmd --add-port=2300/tcp --permanent
reload the added port: firewall-cmd --reload
verification: /etc/fdfs/ There should be four files under .sample
5. Configure tracker and modify base_path (file storage Path) is /opt/fastdfs
mkdir /opt/fastdfs
cp tracker.conf.sample tracker.conf
vim tracker.conf
base_path=/opt/fastdfs
check whether it is started
[root@localhost fdfs]# fdfs_trackerd /etc/fdfs/tracker.conf start
[root@localhost fdfs]# ps -ef|grep tracker.conf Figure 1.5 Configure tracker
[root@localhost fdfs]# netstat -tunlp|grep fdfs
tcp 0 0 0.0.0.0:22122 0.0.0.0:LISTEN 101689/fdfs_tracker
[root@localhost fdfs]# tail /opt/fastdfs/logs/trackerd.log
INFO-FastDFS v5.12, base_path=/opt/fastdfs...
6. Configure storage
cp storage.conf.sample storage.conf
vim storage.conf
mainly modifies the connection address of basepath, storepath and tracker, as well as the http service port configuration of storage.
group_name=group1 # Group name (the first group is group1, the second group is group2, and so on...)
base_path=/opt/fastdfs # The root directory for storing data and log files
store_path0=/opt/fastdfs # The first storage directory, The second storage directory starts with the name: store_path1=xxx, and the other storage directory names are
deduced by analogy... store_path_count=1 # The number of storage paths must match the number of
store_path tracker_server=192.168.1.120:22122 # tracker server IP and port, yes If there are multiple, add multiple lines.
Check whether it is started
[root@localhost fdfs]# fdfs_storaged /etc/fdfs/storage.conf start
[root@localhost fdfs]# netstat -unltp|grep fdfs

[root@localhost fdfs]# tail /opt/fastdfs/logs/storaged.log
mkdir data path: FA…
mkdir data path: FB…
mkdir data path: FC…
mkdir data path: FD…
mkdir data path: FE…
mkdir data path: FF…
data path: /opt/fastdfs/data, mkdir sub dir done…
Use the following command on any storage node to view the status information of the cluster: fdfsmonitor /etc/fdfs/storage.conf If ipaddr = Active appears, it means The storage server has been registered to the tracker server;
7. Install nginx on the storage and configure the fastdfs-nignx module
unzip fastdfs-nginx-module-master.zip
mv fastdfs-nginx-module-master /usr/local/fastdfs-nginx-module
tar -zxvf nginx-1.16.0.tar.gz
cd nginx-1.16.0/
./configure --prefix=/usr/local/nginx --add-module=/usr/local/fastdfs-nginx-module/src/ #Configure fastdfs-nignx module
without error
make
make install
otherwise you need to install the prompted library (
install on demand according to the prompt) yum install -y pcre pcre-devel
yum install -y zlib zlib-devel
yum install -y openssl openssl-devel The
following means success
[root@localhost nginx- 1.16.0]# /usr/local/nginx/sbin/nginx -V

8. Configure client
cd /etc/fdfs/
cp client.conf.sample client.conf
vim client.conf
modify the following items
base_path=/opt/fastdfs # data and log file storage root directory
tracker_server=192.168.1.120:22122 # tracker Server IP and port, there are multiple add-by-line (after testing, localhost cannot be used)
http.tracker_server_port=8080 # Server IP and port number
upload a picture for testing, see if it returns the path, return is successful (note whether the port Open)
[root@localhost Picture]# fdfs_upload_file /etc/fdfs/client.conf a.jpg
group1/M00/00/00/wKgBeF0tkduAP5J0AAR5MnVKolg001.jpg

Figure 1.5 Configure client
9. Configure fastdfs-nginx-module and nginx
cd /etc/fdfs/
cp /usr/local/fastdfs-nginx-module/src/mod_fastdfs.conf.
Vim mod_fastdfs.conf
modify the following items
base_path=/opt /fastdfs # Save log directory
tracker_server=192.168.1.120:22122 # Tracker server IP and port, there are multiple add by line
url_have_group_name = true # Is there a group name in the file url
store_path0=/opt/fastdfs # Store path
copy http.conf ,minme.types to /etc/fdfs under
cp /usr/local/fastdfs/conf/http.conf /usr/local/fastdfs/conf/mime.types /etc/fdfs/
10. Anti- leech configuration, modify the copied http.conf
prepares the corresponding anti-hotlinking prompt picture hotlinking.png in advance, and places it in /etc/fdfs/
cd /etc/fdfs/
vim http.conf to modify the file to the following parameters

http.anti_steal.check_token=true
http.anti_steal.token_ttl=240
http.anti_steal.secret_key=FastDFS123Luntek20100514
http.anti_steal.token_check_fail=/etc/fdfs/hotlinking.png
修改nginx.conf，修改内容如下
vim /usr/local/nginx/conf/nginx.conf

server {
    listen       80;
    server_name  luntek.static;
    location ~/group([0-9])/ {
         alias   /opt/fastdfs/data/;
         ngx_fastdfs_module;
    }
    location / {
        root   html;
        index  index.html index.htm;
    }
    }

Start nginx: /usr/local/nginx/sbin/nginx Restart nginx:
/usr/local/nginx/sbin/nginx -s reload Then access the url of the string splicing generated in the above file:
http://192.168.1.120/ group1/M00/00/00/wKgBeF0tkduAP5J0AAR5MnVKolg001.jpg If there is no anti-theft link configuration, the picture should be displayed. After configuration, 400 BadRequest will be displayed.
11. Startup automatically.
Edit the file vim /etc/rc.d/rc.local and add the following:

fastdfs start

/ usr / bin / fdfs_trackerd /etc/fdfs/tracker.conf restart
/ usr / bin / fdfs_storaged /etc/fdfs/storage.conf restart

nginx start

/usr/local/nginx/sbin/nginx
In centos7, the permissions of the /etc/rc.d/rc.local file have been reduced. You need to add executable permissions to the rc.local file chmod +x /etc/rc. d/rc.local
