安装nginx和nginx-gridfs和mongodb
1.安装依赖包：
[root@mongo_rs1 ~]# yum -y install pcre-devel openssl-devel zlib-devel git gcc gcc-c++
[root@mongo_rs1 zhuyr]# git clone https://github.com/mdirolf/nginx-gridfs.git [root@mongo_rs1 zhuyr]# cd nginx-gridfs/ [root@mongo_rs1 nginx-gridfs]# git checkout v0.8 [root@mongo_rs1 nginx-gridfs]# git branch [root@mongo_rs1 nginx-gridfs]# git submodule init #子模组 'mongo-c-driver' (git://github.com/mongodb/mongo-c-driver.git) 已为路径 'mongo-c-driver' 注册 [root@mongo_rs1 nginx-gridfs]# git submodule update 正克隆到 'mongo-c-driver'... remote: Counting objects: 101193, done. remote: Compressing objects: 100% (128/128), done. remote: Total 101193 (delta 159), reused 195 (delta 127), pack-reused 100938 接收对象中: 100% (101193/101193), 49.45 MiB | 4.55 MiB/s, done. 处理 delta 中: 100% (88309/88309), done. 子模组路径 'mongo-c-driver'：检出 '74cc0b8005fbbc84ec4a0003ff80c68f9e9cc7de'
2.安装nginx
[root@mongo_rs1 zhuyr]# wget http://nginx.org/download/nginx-1.7.9.tar.gz [root@mongo_rs1 zhuyr]# tar -zxvf nginx-1.7.9.tar.gz [root@mongo_rs1 zhuyr]# cd nginx-1.7.9/ [root@mongo_rs1 nginx-1.7.9]# ./configure --prefix=/usr/local/nginx --with-openssl=/usr/include/openssl --add-module=/zhuyr/nginx-gridfs [root@mongo_rs1 nginx-1.7.9]# make -j8 && make install -j8
#如果报错 [root@mongo_rs1 nginx-1.7.9]# ./configure --prefix=/usr/local/nginx --with-openssl=/usr/include/openssl --add-module=/zhuyr/nginx-gridfs #把第3行的-Werror错误去掉 [root@mongo_rs1 nginx-1.7.9]# vi objs/Makefile [root@mongo_rs1 nginx-1.7.9]# make && make install
3.修改配置文件
[root@mongo_rs1 nginx-1.7.9]# vi /usr/local/nginx/conf/nginx.conf
#添加以下内容
location /girdfstest/ {
gridfs pics
field=filename
type=string;
mongo 127.0.0.1:27017;
}
location /girdfsjava/ {
gridfs pics
field=_id
type=objectid;
mongo 127.0.0.1:27017;
}
#gridfstest：访问地址
#field=filename http://172.16.160.91/girdfstest/后面填写什么？
#type=string; 字符窜
#field=_id
#type=objectid;
#pics:数据库
#mongo 127.0.0.1:10001 #mongo的服务器地址及端口
#启动nginx
[root@mongo_rs1 nginx-1.7.9]# /usr/local/nginx/sbin/nginx
#配置修改后重新加载
[root@mongo_rs1 nginx-1.7.9]# /usr/local/nginx/sbin/nginx -s reload
4.安装mongodb
vi /etc/yum.repos.d/mongodb-org-3.4.repo [mongodb-org-3.4] name=MongoDB Repository baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.4/x86_64/ gpgcheck=0 enabled=1 gpgkey=https://www.mongodb.org/static/pgp/server-3.4.asc $ yum -y install mongodb-org 查看修改配置文件 ： vim /etc/mongod.conf
mongodb的配置文件中的bind_ip 默认为127.0.0.1，默认只有本机可以连接。 此时，需要将bind_ip配置为0.0.0.0，表示接受任何IP的连接。 启动mongodb ：systemctl start mongod.service 停止mongodb ：systemctl stop mongod.service
如果报错：
[root@ansible nginx-1.7.9]# journalctl -xe 7月 11 10:54:03 ansible.test yum[797]: Erased: mongodb-org-3.2.20-1.el7.x86_64 7月 11 10:54:04 ansible.test systemd[1]: Reloading. 7月 11 10:54:04 ansible.test systemd[1]: Configuration file /usr/lib/systemd/system/ebtables.service is marked executable.

#解决方法： [root@ansible mongodb]# rm /var/run/mongodb/mongod.pid -f [root@ansible mongodb]# systemctl start mongod.service
5.使用mongofiles工具
[root@mongo_rs1 tmp]# mongofiles put 1.JPG -d pics -t jpg 2018-07-11T11:34:16.002+0800 connected to: localhost added file: 1.JPG [root@mongo_rs1 tmp]# mongofiles list -d pics 2018-07-11T11:34:33.037+0800 connected to: localhost 1.JPG 138424 [root@mongo_rs1 tmp]# mongofiles -d pics get 1.JPG 2018-07-11T13:39:50.775+0800 connected to: localhost finished writing to 1.JPG
6.http访问：
http://172.16.160.91/girdfstest/1.JPG
7.使用java开发：

String mongoHost = "172.16.160.91";
int mongoPort = 27017;
String dbName = "pics";
public MongoDatabase mongoDatabase() throws Exception {
MongoClient mongoClient = new MongoClient(mongoHost, mongoPort);
return mongoClient.getDatabase(dbName);
}

GridFSBucket bucket = GridFSBuckets.create(mongoDatabase());
// 上传
ObjectId fileId = bucket.uploadFromStream(UUID.randomUUID().toString(), in);
System.out.println("上传完成。 文件ID：" + fileId);
}
