搭建双tracker双storage的fastdfs集群
主机概况：
192.168.25.124——运行一个tracker，一个storage（容器内还有一个nginx服务）
192.168.25.125——运行一个tracker，一个storage（容器内还有一个nginx服务）
#1)在192.168.25.124上运行tracker server
docker run -d --name fdfs_tracker \
-v /home/fastdfs/tracker:/export/fastdfs/tracker --net=host \
-e TRACKER_BASE_PATH=/export/fastdfs/tracker \
-e TRACKER_PORT=22123 \
gzlj2018/fastdfs:5.11 \
sh /usr/local/src/tracker.sh
#2)在192.168.25.124上运行storage server
docker run -d --name fdfs_storage \
-v /home/fastdfs/storage:/export/fastdfs/storage --net=host \
-e STORAGE_PORT=23001 \
-e STORAGE_BASE_PATH=/export/fastdfs/storage \
-e STORAGE_PATH0=/export/fastdfs/storage \
-e TRACKER_SERVER=192.168.25.124:22123,192.168.25.125:22123 \
-e GROUP_COUNT=1 \
-e HTTP_SERVER_PORT=8081 \
-e GROUP_NAME=group1 \
gzlj2018/fastdfs:5.11 \
sh /usr/local/src/storage.sh
#3)在192.168.25.125上运行tracker server
docker run -d --name fdfs_tracker \
-v /home/fastdfs/tracker:/export/fastdfs/tracker --net=host \
-e TRACKER_BASE_PATH=/export/fastdfs/tracker \
-e TRACKER_PORT=22123 \
gzlj2018/fastdfs:5.11 \
sh /usr/local/src/tracker.sh
#4)在192.168.25.125上运行storage server
docker run -d --name fdfs_storage \
-v /home/fastdfs/storage:/export/fastdfs/storage --net=host \
-e STORAGE_PORT=23001 \
-e STORAGE_BASE_PATH=/export/fastdfs/storage \
-e STORAGE_PATH0=/export/fastdfs/storage \
-e TRACKER_SERVER=192.168.25.124:22123,192.168.25.125:22123 \
-e GROUP_COUNT=1 \
-e HTTP_SERVER_PORT=8081 \
-e GROUP_NAME=group1 \

日志查看：
进入容器或者在宿主机上查看日志：发现tracker server有两个，其中leader tracker server是192.168.25.124:22123
[root@cool logs]# ip addr show | grep 192.168.25.125

[root@cool logs]# cd /home/fastdfs/storage/logs
[root@cool logs]# tail storaged.log
