一、前言 {#一、前言}
本篇衔接 《FastDFS 环境搭建》 内容进行讲解,上篇文章我们实现了图片上传的功能,但是无法通过 http 进行访问,本篇将解决该问题。
建议读者先浏览 《FastDFS 环境搭建》 再继续浏览本篇文章。
二、安装 {#二、安装}
2.1 下载 fastdfs-nginx-module {#2.1-下载-fastdfs-nginx-module}
Nginx 整合 FastDFS 需要依赖 fastdfs-nginx-module 模块,我们需要将其下载下来。
|-----------|----------------------------------------------------------------------------|
| 1
| git clone https://github.com/happyfish100/fastdfs-nginx-module.git
|
查看下载文件:
|-------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 1 2 3 4 5 6 7 8

2.2 安装 nginx/fastdfs-nginx-module {#2.2-安装-nginx-fastdfs-nginx-module}
笔者通过 yum 方式安装 nginx,具体操作可以访问 《Nginx 快速入门》 。
现在出现一个尴尬的问题:nginx 安装第三方模块需要通过 configure 命令,因此我们还得下载 nginx 源码对第三方模块进行编译安装。
由于笔者已经提前安装 nginx ,键入命令:
|---------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 1 2 3 4 5 6
| [root@fastdfs ~]# nginx -V nginx version: nginx/1.14.0 built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) built with OpenSSL 1.0.2k-fips 26 Jan 2017 TLS SNI support enabled configure arguments: --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-compat --with-file-aio --with-threads --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_mp4_module --with-http_random_index_module --with-http_realip_module --with-http_secure_link_module --with-http_slice_module --with-http_ssl_module --with-http_stub_status_module --with-http_sub_module --with-http_v2_module --with-mail --with-mail_ssl_module --with-stream --with-stream_realip_module --with-stream_ssl_module --with-stream_ssl_preread_module --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -fPIC' --with-ld-opt='-Wl,-z,relro -Wl,-z,now -pie'
|
可以看到 nginx 的版本以及安装好的 nginx 模块,我们需要下载 nginx/1.14.0 的源码:
|-------------------|----------------------------------------------------------------------------------------------------------|
| 1 2 3 4 5
| wget http://nginx.org/download/nginx-1.14.0.tar.gz tar -zxvf nginx-1.14.0.tar.gz cd nginx-1.14.0
|
进入到 nginx-1.14.0 目录后,我们就看到 configure 命令了。
通过源码编译 nginx 模块需要安装依赖包(如果之前通过源码方式安装 nginx 可以忽略该步骤):
|---------------------|---------------------------------------------------------------------------------------------------------------------------------------|
| 1 2 3 4 5 6
| yum install pcre yum install pcre-devel yum install zlib yum install zlib-devel yum install openssl yum install openssl-devel
|
安装完成后,我们现在需要拼接执行命令。
即 ./configure 已安装的模块 --add-module=/root/fastdfs-nginx-module/src,最终的结果如下:
|-----------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 1
| ./configure --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-compat --with-file-aio --with-threads --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_mp4_module --with-http_random_index_module --with-http_realip_module --with-http_secure_link_module --with-http_slice_module --with-http_ssl_module --with-http_stub_status_module --with-http_sub_module --with-http_v2_module --with-mail --with-mail_ssl_module --with-stream --with-stream_realip_module --with-stream_ssl_module --with-stream_ssl_preread_module --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -fPIC' --with-ld-opt='-Wl,-z,relro -Wl,-z,now -pie' --add-module=/root/fastdfs-nginx-module/src
|
执行上边的命令,编译好之后再执行 make 即可。注意,不需要 make install
最后替换 nginx 命令:
|-------------|---------------------------------------------------------------------------|
| 1 2
| cp /usr/sbin/nginx /usr/sbin/nginx.bak cp ./objs/nginx /usr/sbin/
|
三、配置 {#三、配置}
3.1 修改 fastdfs-nginx-module 配置文件 {#3.1-修改-fastdfs-nginx-module-配置文件}
复制 mod_fastdfs 配置文件:
|-----------|-----------------------------------------------------------------------|
| 1
| cp /root/fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/
|
修改 vim /etc/fdfs/mod_fastdfs.conf:
|---------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------|
| 1 2 3 4 5 6 7 8 9
| base_path=/data/fastdfs/tmp tracker_server=192.168.10.110:22122 group_name=light url_have_group_name = true store_path0=/data/fastdfs/storage
|
注意:请确保 /etc/fdfs 有如下 .conf 文件:
|------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14
| [root@fastdfs fdfs]# pwd /etc/fdfs [root@fastdfs fdfs]# ll total 84 -rw-r--r--. 1 root root 1462 Oct 17 01:50 client.conf -rw-r--r--. 1 root root 1461 Oct 16 22:26 client.conf.sample -rw-r--r--. 1 root root 955 Oct 17 04:34 http.conf -rw-r--r--. 1 root root 31172 Oct 17 04:35 mime.types -rw-r--r--. 1 root root 3744 Oct 17 04:22 mod_fastdfs.conf -rw-r--r--. 1 root root 7976 Oct 17 01:57 storage.conf -rw-r--r--. 1 root root 7978 Oct 16 22:26 storage.conf.sample -rw-r--r--. 1 root root 105 Oct 16 22:26 storage_ids.conf.sample -rw-r--r--. 1 root root 7442 Oct 16 23:34 tracker.conf -rw-r--r--. 1 root root 7441 Oct 16 22:26 tracker.conf.sample
|
缺少配置文件,可能会造成后边启动 nginx 失败,如果根据笔者介绍的步骤,应该不会出现缺漏文件的情况。
3.2 修改 nginx 配置文件 {#3.2-修改-nginx-配置文件}
vim /etc/nginx/conf.d/default.conf ,新增 location 配置:
|---------------------------------|----------------------------------------------------------------------------------------------------------------------------------|
| 1 2 3 4 5 6 7 8 9 10 11
| server { server_name 192.168.10.110; location /light/M00 { root /data/fastdfs/storage/data; ngx_fastdfs_module; } ... }
|
保存文件,重启 nginx :
|-----------|-------------------------|
| 1
| nginx -s reload
|
四、测试 {#四、测试}
打开浏览器访问 http://192.168.10.110/light/M00/00/00/wKgKblvG1hmAafZBAADByGKuVUM369.jpg (上篇文章中笔者上传图片后 fdfs 返回的 url 地址),显示效果:
图片正常访问,大功告成。
如果访问不通,检查是否是防火墙问题,或者查看 nginx 日志。
