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。
