Tokumx 代替 Mongodb 群集部署

一, 配置环境:

系统: CentOS 7 x64

tokumx1 ip: 192.168.0.155

tokumx2 ip: 192.168.0.156

tokumx3 ip: 192.168.0.157

二, 部署前准备:

useradd -u 1002 tokumx

tar zxvf tokumx-1.5.1-linux-x86_64-main.tar.gz

mv tokumx-1.5.1-linux-x86_64 /opt/local/tokumx/

mkdir -p /opt/local/tokumx/data/shard

mkdir -p /opt/local/tokumx/data/logs

mkdir -p /opt/local/tokumx/data/config

chown -R tokumx:tokumx /opt/local/tokumx

三, 增加配置文件

vi /opt/local/tokumx/tokumx.conf

-----------------------------------------------------------------

port=27017

fork=true

logpath=/opt/local/tokumx/data/logs/shard.log

pidfilepath=/opt/local/tokumx/tokumx.pid

logappend=true

dbpath=/opt/local/tokumx/data/shard/

shardsvr=true

directio=true

maxConns=20000

replSet=shard1

oplogSize=5000

cacheSize=8G

expireOplogDays=15                  

--------------------------------------------------------------------

四, 启动tokumx 实例

启动之前需要关闭hugepages：

echo never > /sys/kernel/mm/transparent_hugepage/enabled

/opt/local/tokumx/bin/mongod -f /opt/local/tokumx/tokumx.conf

五, 初始化replica set

/opt/local/tokumx/bin/mongo

config={

"_id" : "shard1",

"members" : [

{"_id" : 0, "host" : "192.168.0.155:27017"},

{"_id" : 1, "host" : "192.168.0.156:27017"},

{"_id" : 2, "host" : "192.168.0.157:27017"}

  ]

}

rs.initiate(config)

然后查看集群运行情况：

rs.status()

固定 主服务器

cfg = rs.conf()

cfg.members[0].priority = 1

cfg.members[1].priority = 0.5

cfg.members[2].priority = 0.5

rs.reconfig(cfg)
