1 Aerospike Databases部署前準備工作
- 盡量不要對ssd做RAID,RAID控制器會帶來不必要的延遲
- 如果必須做RAID,建議每塊盤單獨做RAID0。如果做了RAID,需要利用 LSI Mega CL 進行一些優化設定。參考:LSI Mega CLI: [[http://www.aerospike.com/docs/operations/plan/ssd/lsi_megacli.html]]
- SSD硬碟不需要格式化,不需要挂載,直接attach到伺服器主機闆上,Aerospike把SSD當raw disk使用。
- 有些SSD需要預留部分空間給驅動控制器使用,這樣能帶來更好的性能。
對于intel CD S3500的SSD,Aerospike強烈建議進行分區,第一個分區79%,第二個分區21%。 使用第一個分區進行後面的ACT測試
- SSD硬碟在第一次使用之前需要做清零操作,清零操作會清除SSD硬碟硬碟中的資料。新添加SSD硬碟對資料庫存儲容量進行擴容時,隻需要對新添加的SSD硬碟做清零操作(參照下面資訊進行清零操作)。
sudo dd if=/dev/zero of=/dev/<deviceID> bs=1M&
出現提示:No space left on device or an out of space error 說明硬碟清零操作完畢。
2 Aerospike Databases部署步驟
- 依賴環境安裝
sudo yum install openssl-devel sudo yum install gcc gcc-c++
- server端安裝步驟
wget -O aerospike.tgz 'http://aerospike.com/download/server/latest/artifact/el6' tar -xvf aerospike.tgz cd aerospike-server-community-*-el6 sudo ./asinstall # will install the .rpm packages sudo service aerospike start sudo tail -f /var/log/aerospike/aerospike.log | grep cake
wait for it. "service ready: soon there will be cake!"
- 關閉Aerospike Databases節點機器之間的防火牆
- 參考下面配置,修改Aerospike Server端conf檔案。
service { user root group root paxos-single-replica-limit 1 # Number of nodes where the replica count is automatically reduced to 1. pidfile /var/run/aerospike/asd.pid service-threads 32 transaction-queues 32 transaction-threads-per-queue 3 proto-fd-max 100000 fabric-workers 96 microbenchmarks true } logging { # Log file must be an absolute path. file /var/log/aerospike/aerospike.log { context any info } } network { service { address any port 3000 } heartbeat { mode multicast address 239.1.99.222 port 9918 #interface-address 192.168.1.116 # To use unicast-mesh heartbeats, remove the 3 lines above, and see # aerospike_mesh.conf for alternative. # #mode mesh #port 3002 #mesh-seed-address-port 192.168.1.116 3002 #mesh-seed-address-port 192.168.1.117 3002 interval 150 timeout 20 } fabric { port 3001 } info { port 3003 } } namespace test { replication-factor 2 memory-size 75G default-ttl 30d # 30 days, use 0 to never expire/evict. high-water-memory-pct 90 high-water-disk-pct 90 # Warning - legacy data in defined raw partition devices will be erased. # These partitions must not be mounted by the file system. storage-engine device { # Use one or more lines like those below with actual device paths. device /dev/sdb1 #device /dev/sdc1 #device /dev/fioa # The 2 lines below optimize for SSD. scheduler-mode noop write-block-size 128K # Use the line below to store data in memory in addition to devices. # data-in-memory true } }
- 啟動Aerospike Databases
sudo service aerospike start 或者 sudo /etc/init.d/aerospike start
