一.前言：

　　前期，已经搭建好了一套fastdfs文件服务器，一个tracker和一个storage，且部署在同一台服务器上，已经正式投入运行快半年了，1T的空间现在只剩下100G容量了，现在需要扩容，再增加1T。
有两种方案：1.在原有的storage直接挂存储，这样单个storage达到2T；2.另外部署一套storage，作为group2，这样，就是一个tracker对应两个storage，方便维护以及备份转移。
　　现采用第二种方案。

二.前期准备：

　　已经一套fastdfs文件服务器，如果没有，请参考我以前的博客，地址为：https://www.cnblogs.com/lazyInsects/p/9486354.html。

　　另外一台新的1T服务器，centeOS6.5以上，关闭防火墙。

三.开始搭建：

　　
1. 拷贝安装目录下各个.gz文件到/usr/local/src下，解压各个install lib，例如tar -zxvf xxx.tar.gz，这些.gz文件在我的百度网盘，有需要可以联系我。
2.需要先安装 gcc,gcc-c++,perl。命令为
　　yum install gcc;
　　yum install gcc-c++;
　　yun install perl;
 3. 先安装libfastcommon，（需要先安装 gcc,gcc-c++,perl）

    cd libfastcommon

    ./make.sh

    ./make.sh install

    4. 安装FastDFS

    cd FastDFS

    ./make.sh

    ./make.sh install

    5. 修改storage.conf

    cd /etc/fdfs

    cp storage.conf.sample storage.conf

    //创建目录

    mkdir -p /opt/fdfs/storage

    mkdir -p /data/fdfs

    vi storage.conf

    修改项：

    base_path=/opt/fdfs/storage

    group_name=group1

    store_path0=/data/fdfs

    tracker_server=tracker服务器ip:22122

    http.server_port=8080

    6. 拷贝命令到指定目录

    cp /usr/bin/fdfs_storaged /usr/local/bin

    cp /usr/bin/fdfs_monitor /usr/local/bin

    7. 连接目录

    ln -s /usr/include/fastcommon /usr/local/include/fastcommon

    ln -s /usr/include/fastdfs /usr/local/include/fastdfs

    ln -s /usr/lib64/libfastcommon.so /usr/local/lib/libfastcommon.so

    ln -s /usr/lib64/libfdfsclient.so /usr/local/lib/libfdfsclient.so

    8：启动storage

    fdfs_storaged /etc/fdfs/storage.conf start

    重启
fdfs_storaged /etc/fdfs/storage.conf restart

    (/usr/bin/restart.sh /usr/local/bin/fdfs_storaged /etc/fdfs/storage.conf)

    9：查看启动状态

    netstat -unltp | grep fdfs

        查看log： cat /opt/fdfs/stroage/logs/storaged.log  

              or

        tail -f /opt/fdfs/stroage/logs/storage.log

    10: 监控storage状态

    //查看storage状态

    fdfs_monitor /etc/fdfs/storage.conf

    fdfs_monitor /home/fastdfs/fdfs_conf/storage.conf

二：storage上安装nginx

    1：确保依赖安装

    yum install –y openssl-devel pcre-devel zlib-devel

    2：解压/usr/local/src下的相关压缩包

    3：编译和安装nginx

    创建用户和响应的目录和文件，请参考nginx的安装文档

    cd /usr/local/src/nginx-1.8.0

----整段运行------

    ./configure \

    --prefix=/usr \

    --sbin-path=/usr/sbin/nginx \

    --conf-path=/etc/nginx/nginx.conf \

    --error-log-path=/media/disk1/nginx/logs/error.log \

    --pid-path=/var/run/nginx/nginx.pid \

    --lock-path=/var/lock/nginx.lock \

    --user=nginx \

    --group=nginx \

    --with-pcre=/usr/local/src/pcre-8.35 \

    --with-http_ssl_module \

    --with-http_flv_module \

    --with-http_gzip_static_module \

    --http-log-path=/media/disk1/nginx/logs/access.log \

    --http-client-body-temp-path=/media/disk1/nginx/client \

    --http-proxy-temp-path=/media/disk1/nginx/proxy \

    --http-fastcgi-temp-path=/media/disk1/nginx/fcgi \

    --with-http_stub_status_module \

    --with-poll_module \

    --with-http_realip_module \

    --add-module=/usr/local/src/ngx_cache_purge-2.3 \

    --add-module=/usr/local/src/fastdfs-nginx-module/src \

    --with-cc-opt=-Wno-error 

安装：

    make

    make install

    4: 配置mod_fastdfs.conf

        cp /usr/local/src/fastdfs-nginx-module/src/mod_fastdfs.conf /etc/fdfs/

    修改/etc/fdfs/mod_fastdfs.conf配置项

    base_path=/data/fdfs

    tracker_server=tracker服务器io:22122#修改为tracker server信息

    url_have_group_name= true #改为true

    store_path0=/data/fdfs #改为数据存储路径，和storage.conf一样

        group_name=group1

        group_count = 2

    并且在文件末尾加上以下信息：

    [group1]

    group_name=group1

    storage_server_port=23000

    store_path_count=1

    store_path0=/data/fdfs

    5:ln -s /data/fdfs/data /data/fdfs/data/M00

ln -s /opt/file/fdfs/data /opt/file/fdfs/data/M01

    6：拷贝http.conf和mime.type

        cp /usr/local/src/FastDFS/conf/http.conf /etc/fdfs/

        cp /usr/local/src/FastDFS/conf/mime.types /etc/fdfs/

    7：设置启动文件和nginx配置文件

    请参考安装目录下的storage下的nginx和nginx.conf

    location ~/group[1-3]/M00 {

        root /home/fastdfs/data;

        ngx_fastdfs_module;

    }

    修改对应的ip后分别拷贝到/etc/init.d/、/etc/nginx/

        cp /usr/sbin/nginx /etc/init.d/

        如果忘记copy 会报错：[emerg]: getpwnam(“nginx”) failed  ，原因没有注册用户

         chmod u+x nginx

    8: 启动nginx

         cd /usr/sbin/

         ./nginx

        #service nginx start
　　　　重启nginx
　　　　./nginx -s reload
9: 查看启动进程 ps aux | grep nginx cat /media/disk1/nginx/logs/access.log cat /media/disk1/nginx/logs/error.log 如不清楚log位置可在nginx.conf 配置中查看。 安装tracker 和 storage之后，测试 上传文件： 上传： /usr/local/bin/fdfs_upload_file /etc/fdfs/client.conf /usr/local/a.txt 测试： /usr/local/bin/fdfs_test /etc/fdfs/client.conf upload /usr/local/a.txt

四.遇到的问题及解决办法

1.测试上传时生成的链接访问不了
原因：storage.config里面，由于store_path我配置了2个，store_path0和store_path1，但是store_path_count默认是1，忘记修改了，应该改成2.
改完后，重启storage和tracker，命令分别为：fdfs_storaged /etc/fdfs/storage.conf restart和fdfs_trackerd /etc/fdfs/tracker.conf restart

2.打开storage2里面的文件很慢
原因：在tracker服务器的nginx配置代理没配正确，正确配置看上面的内容。
