TFS configuration ha and Failover Test

After configuring multiple dataservers, you need to consider the single point of failure problem of nameserver. This article will introduce how to implement ha for the nameserver of TFS. It is officially recommended to use heartbeat, but the implementation configuration of heartbeat is much more complicated than keepalive, therefore, keepalive is used to implement ha and Failover of namserver.

 

Environment Introduction:

NS Server 1 --> 192.168.1.225

NS Server 2 --> 192.168.1.226

Ns vip --> 192.168.1.229

Data Server 1 --> 192.168.1.227

Data Server 2 --> 192.168.1.228

Nginx server --> 192.168.1.12

Disable all name servers and data servers of TFS before starting.

# /usr/local/tfs/scripts/tfs  stop_ns nameserver exit SUCCESSFULLY  # /usr/local/tfs/scripts/tfs stop_ds 1-3 dataserver 1 exit SUCCESSFULLY  dataserver 2 exit SUCCESSFULLY  dataserver 3 exit SUCCESSFULLY

I. Configure TFs Name Server

225 server: # grep-V '^ #'/usr/local/TFS/CONF/ns. conf | grep-V '^ $' [public] log_size = clerk = 16 log_level = clerk = 10240 Port = 8w.work_dir =/usr/local/tfsdev_name = eth0thread_count = 4ip_addr = 192.168.1.229 // 229 IP Address: VIP [nameserver] hosts = 300 hosts = 192.168.1.225 | 192.168.1.226group _ mask = 255.255.255.255block _ max_size = 83886080 max_replication = 2min_replication = 2 servers = 3600cluster_id = physical _ = 50max_write_filecount = 16heart_thread_count = 2 bytes = 10repl_max_time = Cost = 15 compact_max_load = Cost = 120build_plan_ratio = Cost = 60000000 bytes = 2 bytes = 5add_primary_block_count = 3block_chunk_num = 32task_percent_sec_size = 200 task_max_queue_size = bytes = 1 # cd/usr/local/# tar-zcvpf TFs. tgz TFs/# SCP TFs. tgz 192.168.1.226:/usr/local/226 server: # cd/usr/local/# tar-zxvpf TFs. tgz

Ii. Configure ha

225 server # cd/usr/local/src/# wget http://www.keepalived.org/software/keepalived-1.2.13.tar.gz# tar-zxvpf keepalived-1.2.13.tar.gz # cd keepalived-1.2.13 #. /configure -- prefix =/usr/local/keepalived # Make & make install # Cat/usr/local/keepalived/etc/keepalived. conf global_defs {router_id tfs_ns} vrrp_script failed {script "killall-0 blocks" interval 2 weight 2} vrrp_instance vi_1 {state master interface eth0 limit 23 priority 101 limit 1 authentication {auth_type limit password_123} virtual_ipaddress {192.168.1.229/24 BRD 192.168.255.255 Dev eth0 label eth0: 0} track_interface {eth1} track_script {chk_nameserver }}# CD/usr/local/# tar-zcvpf keepalived. tgz keepalived/# SCP keepalived. tgz 192.168.1.226:/usr/local/226 server: # cd/usr/local/# tar-zxvpf keepalived. tgz # tar-zxvpf TFs. tgz # Cat/usr/local/keepalived/etc/keepalived. conf global_defs {router_id tfs_ns} vrrp_script failed {script "killall-0 blocks" interval 2 weight 2} vrrp_instance vi_1 {state master interface eth0 limit 23 priority 100 limit 1 authentication {auth_type limit password_123} virtual_ipaddress {192.168.1.229/24 BRD 192.168.255.255 Dev eth0 label eth0: 0} track_interface {eth1} track_script {chk_nameserver }}

3. modify data server configurations

# Grep-2 'vip '/usr/local/TFS/CONF/Ds. conf // The two data servers perform the same modification operation [dataserver] # nameserver ip addr (VIP) ip_addr = 192.168.1.229

4. Start the service

#/Usr/local/TFS/scripts/TFS start_ds 1-3/227,228 servers run #/usr/local/TFS/scripts/TFS start_ns // 225,226 servers respectively run #/usr/local/keepalived/sbin/keepalived-F/usr/local/keepalived/etc/keepalived. conf // on the 225,226 server, the 225 server will become the master node and register VIP # ip

The nginx configuration file needs to be slightly modified, pointing to VIP # grep '000000'/usr/local/nginx/CONF/nginx. conf server 192.168.1.229: 8108; # service nginx restart http: // 192.168.1.12: 7500/V1/TFS/t1brxtbyjt1rcvbvdk
