1 Aerospike Databases部署前准备工作

• 尽可能不要对ssd做RAID，RAID控制器会带来没必要要的延迟
• 如果必须做RAID，建议每块盘单独做RAID0。如果做了RAID，需要利用 LSI Mega CL 进行1些优化设置。参考：LSI Mega CLI: [[http://www.aerospike.com/docs/operations/plan/ssd/lsi_megacli.html]]
• SSD硬盘不需要格式化，不需要挂载，直接attach到服务器母板上，Aerospike把SSD当raw disk使用。
• 有些SSD需要预留部份空间给驱动控制器使用，这样能带来更好的性能。
  

  对intel CD S3500的SSD，Aerospike强烈建议进行分区，第1个分区79%，第2个分区21%。
  使用第1个分区进行后面的ACT测试
  

• SSD硬盘在第1次使用之前需要做清零操作，清零操作会清除SSD硬盘硬盘中的数据。新添加SSD硬盘对数据库存储容量进行扩容时，只需要对新添加的SSD硬盘做清零操作（参照下面信息进行清零操作）。
  

  sudo dd if=/dev/zero of=/dev/<deviceID> bs=1M&
  

出现提示：No space left on device or an out of space error 说明硬盘清零操作终了。

2 Aerospike Databases部署步骤

• 依赖环境安装
  

  sudo yum install openssl-devel
  sudo yum install gcc gcc-c++
  

• server端安装步骤
  

  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!"

• 关闭Aerospike Databases节点机器之间的防火墙
• 参考下面配置，修改Aerospike Server端conf文件。
  

  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
          }
  }

  
  
• 启动Aerospike Databases
  

  sudo service aerospike start 或 sudo  /etc/init.d/aerospike  start 

生活不易，码农辛苦
