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'...

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

#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
