Method of Web Access Fastdfs

As teacher Yu in V4.05 after the version of the built-in HTTP service removed, so even if you test the upload success, you can not access. We recommend that you use the Fastdfs-nginx-module module with Nginx,
After building the FASTDFS system, we can build the Web Access function.
The general idea has the following two kinds
1. Directly install the Nginx extension module on the Fastdfs collection Fastdfs-nginx-module
or directly install the Apache extension module on the Fastdfs collection Fastdfs-apache-module 2. After installing the Web software, the function of Fastdfs-nginx-module is realized by configuring Nginx.
The first kind (recommended).
Download Nginx and plug-in Fastdfs-nginx-module-master.zip the two software (if Nginx has been installed, need to recompile again, compile the plugin loaded)
(if Nginx is installed with Yum, you need to download the same version of Yum install package, recompile)
Here from the beginning install: Unzip: # TAR-ZXVF Nginx-1.13.5.tar.gz
# Unzip Fastdfs-nginx-module-master.zip
Installing Nginx and Fastdfs plugins:
./configure--prefix=/usr/local/nginx--ADD-MODULE=/HOME/PACKAGES/FASTDFS-NGINX-MODULE-MASTER/SRC
Consecutive error: Error: The HTTP rewrite module requires the PCRE library ....
Workaround: Yum Install pcre-devel.x86_64 error: The HTTP gzip module requires the Zlib library ....
Solution: Yum Install zlib-devel.x86_64
Compilation succeeded:
Adding module IN/HOME/PACKAGES/FASTDFS-NGINX-MODULE-MASTER/SRC+ Ngx_http_fastdfs_module was configured

Continue installation: # make # make Install
Go to the Nginx installation directory and modify its configuration file: # cd/usr/local/nginx/conf # VI nginx.conf Add the following:
location/m00 {root/home/yuqing/fastdfs/data;         Ngx_fastdfs_module; }

Create a new Soft connection: # Ln-s/home/yuqing/fastdfs/data/home/yuqing/fastdfs/data/m00
Copy and modify the mod_fastdfs.conf file: # CP mod_fastdfs.conf/etc/fdfs/# vi/etc/fdfs/mod_fastdfs.conf modified here: tracker_server= 10.0.0.42:22122
(Copy these two files to the Fdfs configuration file, or you can not access Nginx) (# cp/home/fastdfs-5.11/conf/http.conf/etc/fdfs/)
(# cp/home/fastdfs-5.11/conf/mime.types/etc/fdfs/)

Restart Nginx:
#/usr/local/nginx/sbin/nginx-s stop;
#/usr/local/nginx/sbin/nginx

Here's a look at the mod_fastdfs.conf file:# Connect timeout in seconds # default value is 30s connect_timeout=2 connection time-out

If the information is not read from the Tracket server, the following three parameters are in effect # storage sync file max delay seconds # same as tracker.conf # valid only when Load_fdfs_param       Eters_from_tracker is False # since V1.12 # default value was 86400 seconds (one day) Storage_sync_file_max_delay = 86400 When Load_fdfs_parameters_from_tracker is set to False, this parameter takes effect the maximum delay time of the synchronization file, same as the parameters in the tracker.conf file
The default is one day

Set no 0, support multiple group groups on this storage server set 0 to only one group If there are multiple groups on the server, the settings for the group are like this [group1], [group2], ..., [GROUPN] The default is 0, a set of

Second, the direct use of Web Access this is relatively simple, just need to assign the Web root directory to the Fastdfs storage directory is available

Third, several ideas of Web Access Fastdfs

3.1 Use group name only
Suitable for large pictures, group groups, each group has a backup access address is similar to picture.xxx.com/groupx/m00/......jpg only need a domain name;
When you upload a picture, the value returned directly + the domain name is saved as a picture name: Picture.xxx.com/groupx/m00/......jpg The front end uses one nginx to do the reverse proxy + load balancer configuration as follows:Upstream group1{server group1_storage1:80;
Server group1_storage2:80;
} upstream group2{server group2_storage1:80;
Server group2_storage2:80;
}
location/group1/m00{proxy_pass http://group1;} location/group2/m00{proxy_pass http://group2;}
Note: The machines in group1 and group2 are properly configured nginx.conf storage.conf and mod_fastdfs.conf files in nginx.conf
location/group1/m00 {root/home/yuqing/fastdfs/data; Ngx_fastdfs_module;}
Pay particular attention to the two group names in the mod_fastdfs.conf file, whether the URLs contain group names
Group_name=
Url_have_group_name =


3.2 Using domain names only (deployed production environments)
Applies to fewer pictures, each group is a single run, no backup situation
