安裝libfastcommon, fastdfs5.X 取消了對libevent的依賴,添加了對libfastcommon的依賴. wget https://github.com/happyfish100/libfastcommon/archive/master.zip unzip libfastcommon-master.zip cd libfastcommon-master/ ./make.sh ./make.sh install ``` ##### 下載安裝FastDFS ```python tar xvf FastDFS_v5.05.tar.gz -C /usr/local/fast/ cd /usr/local/fast/FastDFS/ ./make.sh && ./make.sh install # 建立軟連結 ln -s /usr/lib64/libfastcommon.so /usr/local/lib/libfastcommon.so ln -s /usr/lib64/libfastcommon.so /usr/lib/libfastcommon.so ln -s /usr/lib64/libfdfsclient.so /usr/local/lib/libfdfsclient.so ln -s /usr/lib64/libfdfsclient.so /usr/lib/libfdfsclient.so ``` ##### 修改fastdfs配置檔案 > 修改fastdfs服務指令碼bin目錄為/usr/local/bin,但是實際我們安裝在了/usr/bin/下面。所以我們需要修改FastDFS配置檔案中的路徑,也就是需要修改倆 個配置檔案: 命令:vim /etc/init.d/fdfs_storaged 然後輸入全域性替換命令:`%s+/usr/local/bin+/usr/bin`並按回車即可完成替換 `修改tracker.conf` > 第一處:base_path,將預設的路徑修改為/fastdfs/tracker。第二處:store_lookup,該值預設是2(即負載均衡策略),現在把它修改為0(即輪詢策略,修改成這樣方便一會兒我們進行測試,當然,最終還是要改回到2的。如果值為1的話表明要始終向某個group進行上傳下載操作,這時下圖中的"store_group=group2"才會起作用,如果值是0或2,則 ```python mkdir -p /fastdfs/tracker cd /etc/fdfs cp tracker.conf.sample tracker.conf vim /etc/fdfs/tracker.conf base_path=/fastdfs/tracker store_lookup=0 # 然後將這個配置拷貝到另一臺tracker上 ``` ##### 啟動tracker ```python # 啟動tracker fdfs_trackerd /etc/fdfs/tracker.conf start or service fdfs_trackerd start # 驗證埠 lsof -i:22122 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME fdfs_trac 15222 root 5u IPv4 49284 0t0 TCP *:22122 (LISTEN) fdfs_trac 15222 root 18u IPv4 49304 0t0 TCP tracker1:22122->192.168.43.60:63056 (ESTABLISHED) ``` #### 部署Storage ##### 配置storage.conf ```python mkdir -p /fastdfs/storage vim /etc/fdfs/storage.conf base_path=/fastdfs/storage store_path0=/fastdfs/storage store_path_count=1 disabled=false tracker_server=192.168.43.234:22122 tracker_server=192.168.43.233:22122 group_name=group1 # 分配的group1可以直接將此檔案拷貝過去,group2修改下group_name就行了 ``` ##### 啟動storage ```python service fdfs_trackerd start # 驗證埠 lsof -i:23000 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME fdfs_stor 14105 root 5u IPv4 44719 0t0 TCP *:inovaport1 (LISTEN) fdfs_stor 14105 root 20u IPv4 45629 0t0 TCP group1:inovaport1->192.168.43.60:44823 (ESTABLISHED) fdfs_monitor /etc/fdfs/storage.conf |grep ACTIVE [2020-07-03 20:35:09] DEBUG - base_path=/fastdfs/storage, connect_timeout=30, network_timeout=60, tracker_server_count=2, anti_steal_token=0, anti_steal_secret_key length=0, use_connection_pool=0, g_connection_pool_max_idle_time=3600s, use_storage_id=0, storage server id count: 0 ip_addr = 192.168.43.24 ACTIVE ip_addr = 192.168.43.60 (group1) ACTIVE ip_addr = 192.168.43.128 ACTIVE ip_addr = 192.168.43.97 ACTIVE ``` ##### 驗證服務可用性 ```python #
