zookeeper集群部署(伪集群,版本号zookeeper-3.4.10)
在虚拟机上进行伪集群部署,部署一个节点,拷贝两个,完成三个节点的部署
1,zookeeper下载,下载zookeeper安装包,并解压
2,进入zookeeper的conf目录下,对文件zoo_sample.cfg进行重命名为zoo.cfg,并进行如下编辑:
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/srv/new_solr/solrCloud/zk-1/zookeeper-3.4.10/data
dataLogDir=/srv/new_solr/solrCloud/zk-1/zookeeper-3.4.10/data/log
# the port at which the clients will connect
clientPort=2281
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
autopurge.purgeInterval=1
server.1=10.1.88.101:2188:3188
server.2=10.1.88.101:2288:3288
server.3=10.1.88.101:2388:3388
主要是对 dataDir 数据目录,dataLogDir日志目录,clientPort端口号等参数进行目录设置,并设置server1,2,3的IP及通信端口。
3,进入zookeeper的data目录下,对myid文件进行编辑,直接在myid文件中写入1即可,id值与zoo.cfg中的server.*是对应的, server.1的myid文件,就写入1。其他节点就是对应的2,3。如果没有myid文件,就执行下述命令创建并写入。
echo 1 > /srv/new_solr/solrCloud/zk-1/zookeeper-3.4.10/data/myid
4,复制配置好的server1,粘贴为server2,server3,并更改相应zoo.cfg的端口为2282myid为2,端口为2283的myid为3。
