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。
