项目中使用了FastDFS作为文件系统，这里记录一下它的安装和配置过程
项目场景
由于是测试环境，所以只提供了一台服务器，后续软件的安装和配置都在这台服务器上完成
准备工作
| 软件名称 | 下载地址 |
|---|---|
| FastDFS | fastdfs-5.10.tar.gz |
| libfastcommon | libfastcommon-1.0.35.tar.gz |
| nginx | nginx-1.9.9.tar.gz |
| fastdfs-nginx-module | fastdfs-nginx-module_v1.16.tar.gz |
Tracker安装配置
1、安装fastdfs公共库libfastcommon，注意fastdfs和libfastcommon的安装目录，后面安装fastdfs-nginx-module时需要进行相关配置
cp /mnt/download/libfastcommon-1.0.35.tar.gz /usr/local/
cd /usr/local
tar -zxvf libfastcommon-1.0.35.tar.gz
cd libfastcommon-1.0.35
./make.sh
./make.sh install
2、安装fastdfs
cp /mnt/download/fastdfs-5.10.tar.gz /usr/local/
cd /usr/local
tar -zxvf fastdfs-5.10.tar.gz
cd fastdfs-5.10
./make.sh
./make.sh install

注意一下存放数据和日志的目录，启动后需要查看日志信息
4、启动Tracker
fdfs_trackerd /etc/fdfs/tracker.conf
5、查看日志
为了确保Tracker启动成功，我们可以在刚在配置的日志目录中查看日志信息
cd /mnt/fastdfs/logs
cat trackerd.log
[2017-09-14 15:42:11] INFO - FastDFS v5.10, base_path=/mnt/fastdfs, run_by_group=, run_by_user=, connect_timeout=30s, network_timeout=30s, port=22122, bind_addr=, max_connections=256, accept_threads=1, work_threads=4, min_buff_size=8192, max_buff_size=131072, store_lookup=2, store_group=, store_server=0, store_path=0, reserved_storage_space=10.00%, download_server=0, allow_ip_count=-1, sync_log_buff_interval=10s, check_active_interval=120s, thread_stack_size=64 KB, storage_ip_changed_auto_adjust=1, storage_sync_file_max_delay=86400s, storage_sync_file_max_time=300s, use_trunk_file=0, slot_min_size=256, slot_max_size=16 MB, trunk_file_size=64 MB, trunk_create_file_advance=0, trunk_create_file_time_base=02:00, trunk_create_file_interval=86400, trunk_create_file_space_threshold=20 GB, trunk_init_check_occupying=0, trunk_init_reload_from_binlog=0, trunk_compress_binlog_min_interval=0, use_storage_id=0, id_type_in_filename=ip, storage_id_count=0, rotate_error_log=0, error_log_rotate_time=00:00, rotate_error_log_size=0, log_file_keep_days=0, store_slave_file_use_link=0, use_connection_pool=0, g_connection_pool_max_idle_time=3600s

出现上述信息表示Tracker已启动成功
6、遇到的问题
Tracker启动后，如果改了Tracker的配置文件想要重新启动，执行启动命令后发现日志中报错
[2017-09-14 15:29:19] INFO - FastDFS v5.10, base_path=/mnt/fastdfs, run_by_group=, run_by_user=, connect_timeout=30s, network_timeout=30s, port=22122, bind_addr=, max_connections=256, accept_threads=1, work_threads=4, min_buff_size=8192, max_buff_size=131072, store_lookup=2, store_group=, store_server=0, store_path=0, reserved_storage_space=10.00%, download_server=0, allow_ip_count=-1, sync_log_buff_interval=10s, check_active_interval=120s, thread_stack_size=64 KB, storage_ip_changed_auto_adjust=1, storage_sync_file_max_delay=86400s, storage_sync_file_max_time=300s, use_trunk_file=0, slot_min_size=256, slot_max_size=16 MB, trunk_file_size=64 MB, trunk_create_file_advance=0, trunk_create_file_time_base=02:00, trunk_create_file_interval=86400, trunk_create_file_space_threshold=20 GB, trunk_init_check_occupying=0, trunk_init_reload_from_binlog=0, trunk_compress_binlog_min_interval=0, use_storage_id=0, id_type_in_filename=ip, storage_id_count=0, rotate_error_log=0, error_log_rotate_time=00:00, rotate_error_log_size=0, log_file_keep_days=0, store_slave_file_use_link=0, use_connection_pool=0, g_connection_pool_max_idle_time=3600s

这是因为此时Tracker已经启动了，再执行启动命令就会报错地址已被使用，此时可以执行restart命令进行重启
fdfs_trackerd /etc/fdfs/tracker.conf restart
或者
ps -ef | grep tracker
#杀死对应的进程号
kill -9 xxxx
fdfs_trackerd /etc/fdfs/tracker.conf
Storage安装配置

这是因为此时Storage已经启动了，再执行启动命令就会报错地址已被使用，此时可以执行restart命令进行重启
fdfs_storaged /etc/fdfs/storage.conf restart
或者
ps -ef | grep storage
#杀死对应的进程号

fdfs_storaged /etc/fdfs/storage.conf
之前阿里云ESC实例迁移，导致服务器内网ip地址发生了改变，重启Storage时日志报错
[2017-09-14 15:04:54] ERROR - file: storage_ip_changed_dealer.c, line: 186, connect to tracker server 10.163.174.222:22122 fail, errno: 110, error info: Connection timed out
这是由于Storage配置文件中tracker_server的ip地址还是旧地址，所以会出现连接超时的问题，将配置文件中的地址改成新的地址重启Storage
Storage上fastdfs-nginx-module安装配置
1、配置fastdfs-nginx-module所需的配置文件，包括mod_fastdfs.conf，http.conf，mime.types
配置mod_fastdfs.conf
vi /etc/fdfs/mod_fastdfs.conf

注意CORE_INCS和CFLAGS两项的配置
Storage上nginx安装配置
1、建立nginx用户
groupadd nginx
useradd -g nginx nginx --shell=/sbin/nologin
2、安装配置
cp /mnt/download/nginx-1.9.9.tar.gz /usr/local/
cd /usr/local
tar -zxvf nginx-1.9.9.tar.gz
cd nginx-1.9.9
./configure --prefix=/usr/local/nginx --add-module=/usr/local/fastdfs-nginx-module/src --group=nginx --user=nginx
make && make install
3、更改nginx目录权限
chown -R nginx:nginx /usr/local/nginx
4、配置文件nginx.conf
提供一个最简单的配置方式供参考，由于项目中nginx还做了其他处理，配置文件比较复杂，这里就不贴出来了
user nginx;
worker_processes 1;
events {
worker_connections 1024;
}
http {
server {
listen 80;
server_name localhost;
# group1为Storage所在的group
location /group1/M00 {
# Storage的data目录
root /mnt/fastdfs/data;
# 由于fastdfs保存的文件名已经编码，源文件名将丢失，应用可通过在请求url后加oname参数指定源文件名
if ($arg_oname != ''){
add_header Content-Disposition "attachment;filename=$arg_oname";
}
# 调用nginx-fastdfs-module模块
ngx_fastdfs_module;
}
}
}
5、启动nginx
两种方式
cd /usr/local/nginx/sbin/
./nginx -s reload
或者
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
