通过之前的努力，已经搭建好了一套基本的tfs环境，包括一台nameserver和一台dataserver以及独立的nginx-tfs，而在实际应用中的分布式文件系统，只有一台dataserver明显是不行的，因而本文将介绍tfs环境下添加data server的操作和配置过程。
环境介绍：
Tfs nameserver服务器IP: 192.168.1.225
Tfs dataserver服务器IP: 192.168.1.227
新增tfs dataserver服务器IP：192.168.1.228
Nginx tfs服务器IP：192.168.1.12
一：228服务器上安装tfs软件，修改配置文件
| 1 2 3 4 5 6 7 8 9 10 11 | 227服务器： # cd /usr/local/ # tar -zcvpf tfs.tgz tfs/ # scp tfs.tgz 192.168.1.228:/usr/local/ 228服务器： # cd /usr/local/ # tar -zxvpf tfs.tgz # cd tfs # rm -rf dataserver_* # df -h |grep data |
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 | # grep -v '^#' /usr/local/tfs/conf/ds.conf |grep -v '^$' [public] log_size=1073741824 log_num = 16 log_level=info task_max_queue_size = 10240 port = 9998 work_dir=/usr/local/tfs dev_name= eth0 thread_count = 4 ip_addr = 192.168.1.228 [dataserver] ip_addr = 192.168.1.225 ip_addr_list = 192.168.1.225|192.168.1.226 port = 8108 heart_interval = 2 check_interval = 2 replicate_threadcount = 2 block_max_size = 7549747 dump_visit_stat_interval = 60 backup_type = 1 backup_path = /data/tfs mount_name = /tfs/data mount_maxsize = 20971520 base_filesystem_type = 1 superblock_reserve = 0 avg_file_size = 40960 mainblock_size = 7549747 extblock_size = 419430 block_ratio = 0.5 hash_slot_ratio = 0.5 ds_thread_count = 4 |
二：对磁盘进行初始化，启动dataserver服务
| 1 2 3 | # cd /usr/local/tfs/scripts/ # sh stfs format 1-3 # df -h |grep data |
| 1 2 3 4 5 | # sh tfs start_ds 1-3 dataserver 1 is up SUCCESSFULLY pid: 29264 dataserver 2 is up SUCCESSFULLY pid: 29290 dataserver 3 is up SUCCESSFULLY pid: 29309 # netstat -ntpl |grep data |
三： 查看添加是否成功，修改nameserver replicate为2
| 1 2 3 4 5 6 7 8 9 10 11 12 13 | Name server服务器 # grep 'replication' /usr/local/tfs/conf/ns.conf max_replication = 2 min_replication = 2 # /usr/local/tfs/scripts/tfs stop_ns nameserver exit SUCCESSFULLY # /usr/local/tfs/scripts/tfs start_ns nameserver is up SUCCESSFULLY pid: 12037 # /usr/local/tfs/bin/ssm -s 192.168.1.225:8108 show > machine -a |
# /usr/local/tfs/bin/ssm -s 192.168.1.225:8108 -i show server
# tail -f /usr/local/tfs/logs/nameserver.log
四：上传，读取测试，可以看到shadow文件存储到了228上
| 1 2 | # /usr/local/tfs/bin/tfstool -s 192.168.1.225:8108 TFS> put /etc/passwd |
| 1 | TFS> put /etc/shadow |
