背景
原本使用redis，但是redis cluster不是很成熟，选用了相似的Aerospike
配置文件
默认配置文件地址
vim /etc/aerospike/aerospike.conf
# Aerospike database configuration file.
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 4
transaction-queues 4
transaction-threads-per-queue 4
proto-fd-max 15000
}
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 mesh
address 10.100.1.235
port 3102
# To use unicast-mesh heartbeats, remove the 3 lines above, and see
# aerospike_mesh.conf for alternative.
#mesh-seed-address-port 10.100.1.170 3102
#mesh-seed-address-port 10.100.1.190 3102
#mesh-seed-address-port 10.100.1.116 3102
interval 150
timeout 10
}
fabric {
port 3101
}
info {
port 3103
}
}
namespace dfp {
replication-factor 2 #一般为2，最大不超过3
memory-size 4G
default-ttl 0 # 30 days, use 0 to never expire/evict.
storage-engine memory
# To use file storage backing, comment out the line above and use the
# following lines instead.
# storage-engine device {
# file /opt/aerospike/data/bar.dat
# filesize 16G
# data-in-memory true # Store data in memory in addition to file.
# }
}
当需要单节点时，注释掉 heartbeat中其他的节点
需要多节点时，在heartbeat中添加即可
不过需要注意的是复制因子replication-factor 2，最大不超过3，否则会引起性能的急剧下降
保存配置后，重启并查看aerospike状态
/etc/init.d/aerospike restart
/etc/init.d/aerospike status
