Background:
1. Do a picture upload small item.
2. Image upload, need to manage multiple graphs.
3. Image upload, need to store to Fastdfs.
4.Fastdfs pictures, and nginx combination.
5.Nginx images obtained from Fastdfs need to use thumbnails.
A. You can use the original image in case you don't need a thumbnail or a small picture.
B. If a thumbnail is required, specify the target width and height to get a thumbnail of the specified width and height.

1th Step: Check the Nginx compile and install the command, which modules are installed
/usr/local/nginx/sbin/nginx-v
Nginx version:nginx/1.8.0
Built by GCC 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC)
Configure arguments:--ADD-MODULE=/ROOT/SOFT/FASTDFS-NGINX-MODULE-MASTER/SRC
cd/root/soft/nginx-1.8.0
./configure--prefix=/root/soft/--add-module=/root/soft/fastdfs-nginx-module-master/src--with-http_image_filter _module--with-http_realip_module--with-debug
An error.
./configure:error:the HTTP Image Filter module requires the GD library.
You can either does not enable the module or install the libraries.
2nd step: Install the GD library
#这种不行, my own yy.
Yum Install GD

According to their own YY way, can not start.
Baidu Search "The HTTP image filter module requires the GD library", find the following way ~

complete!
3rd step: There are binaries in this directory
/root/soft/nginx-1.8.0/objs
Still under the directory "/root/soft/nginx-1.8.0"
The original Nginx binary file
-rwxr-xr-x 1 root root 3322288 Oct 14:29 nginx
The generated nginx is compiled
-rwxr-xr-x 1 root root 3480087 Nov 5 18:10 Nginx
A little bit bigger, this should be the effect of adding a module
CP./objs/nginx/usr/local/nginx/sbin/
[email protected] nginx-1.8.0]# CP./objs/nginx/usr/local/nginx/sbin/
Cp:overwrite '/usr/local/nginx/sbin/nginx '? Y
Cp:cannot Create regular file '/usr/local/nginx/sbin/nginx ': Text file busy
4th Step: Stop Nginx 2 processes, again CP
[Email protected] conf]# Ps-ef|grep Nginx
Root 11648 5064 0 18:18 pts/0 00:00:00 grep nginx
Root 30321 1 0 Oct29? 00:00:00 Nginx:master Process/usr/local/nginx/sbin/nginx
Nobody 30322 30321 0 Oct29? 00:00:08 Nginx:worker Process

[Email protected] conf]# kill-9 30322
[Email protected] conf]# Ps-ef|grep Nginx
Root 11672 5064 0 18:19 pts/0 00:00:00 grep nginx
Re-execute CP command
5th step: Check the configuration and find the boot error
[Email protected] conf]#/usr/local/nginx/sbin/nginx-t
Nginx: [alert] could not open error log file:open () "/root/soft//logs/error.log" failed (2:no such file or directory)
2015/11/05 18:20:52 [Emerg] 11697#0:open () "/root/soft//conf/nginx.conf" failed (2:no such file or directory)
Nginx:configuration file/root/soft//conf/nginx.conf Test Failed
Should be compiled--prefix/root/soft caused by, before the installation, not specified, the default may be "/usr/local".
6th step: You can start by specifying the path to the configuration file.
Nginx-c </path/to/config>
This command parameter specifies a new nginx configuration file to replace the default Nginx configuration file, if you are not sure whether the new Nginx configuration file syntax is correct, you can use the Nginx command-t parameter to test, the-t parameter means not to run the configuration file, but just the test configuration file, that is,
Nginx-t-C </path/to/config>
This time, I'll just recompile.
./configure--prefix=/usr/local/nginx--add-module=/root/soft/fastdfs-nginx-module-master/src--with-http_image_ Filter_module--with-http_realip_module--with-debug
Make
CP./objs/nginx/usr/local/nginx/sbin/
7th step: Image_filter instruction, no more error.
Location ~ group1/m00/(. +) \.? (.+) {
Alias/home/fastdata/data;
Ngx_fastdfs_module;
Image_filter Resize 200 220;
}
