FastDFS增加path横向扩容

## **FastDFS增加path横向扩容** ##

> 关注点:
> 
> 1.规划好新的挂载点. \#\#目前环境的规则为/mnt/fdfs01
> 
> 2.集群内的每个节点的path数(store\_path\_count)必须一致.
> 
> 3.每个集群节点的path路径和大小最好一致.

### 操作步骤: ###

#### 一、停止FDFS服务 ####

systemctl stop fdfs_storaged.service fdfs_trackerd.service

#### 二、修改fastdfs配置(*每个节点都需要修改*) ####

cd /etc/fdfs/
    vim storage.conf

# 修改完配置如下：
    
    disabled=false
    group_name=ahFastDFS
    bind_addr=
    client_bind=true
    port=23000
    connect_timeout=30

    accept_threads=1
    work_threads=4
    disk_rw_separated = true
    disk_reader_threads = 1
    disk_writer_threads = 1
    sync_wait_msec=50
    sync_interval=0
    sync_start_time=00:00
    sync_end_time=23:59
    write_mark_file_freq=500
    store_path_count=2						//修改为2 原为1
    store_path0=/opt/fdfs_storage_data		//原有path
    store_path1=/mnt/fdfs01					//新增path
    subdir_count_per_path=256
    tracker_server=192.168.1.179:22122

    sync_binlog_buff_interval=10
    sync_stat_file_interval=300
    thread_stack_size=512KB
    upload_priority=10
    if_alias_prefix=
    check_file_duplicate=0
    file_signature_method=hash
    key_namespace=FastDFS
    keep_alive=0
    use_access_log = false

    file_sync_skip_invalid_record=false
    use_connection_pool = false
    connection_pool_max_idle_time = 3600
    http.domain_name=
    http.server_port=8888

vim mod_fastdfs.conf

# 修改完配置如下：
    
    connect_timeout=2
    network_timeout=30
    load_fdfs_parameters_from_tracker=true
    storage_sync_file_max_delay = 86400
    use_storage_id = false
    storage_ids_filename = storage_ids.conf
    tracker_server=192.168.1.179:22122
    storage_server_port=23000
    group_name=group1
    url_have_group_name = true
    store_path_count=2
    log_level=info
    log_filename=
    response_mode=proxy
    if_alias_prefix=
    flv_support = true
    flv_extension = flv
    group_count = 1
    [group1]
    group_name=ahFastDFS
    storage_server_port=23000
    store_path_count=2							//修改为2 原为1
    store_path0=/opt/fdfs_storage_data			//原有path
    store_path1=/mnt/fdfs01						//新增path
    base_path=/opt/fdfs_storage

#### 三、启动服务 ####

systemctl stop fdfs_storaged.service fdfs_trackerd.service

#### 四、查看各节点的状态 ####

fdfs_monitor /etc/fdfs/client.conf
    fdfs_monitor /etc/fdfs/client.conf | grep ACTIVE

#### 五、文件写入读取测试 ####

略…–开发补充。
