【zookeeper】集群安装

蓝晶灵

　　1.解压(按照简单安装操作)
　　2.修改配置文件
vim zoo.cfg
-----------
# 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=/usr/local/zookeeper/data
dataLogDir=/usr/local/zookeeper/log
# the port at which the clients will connect
clientPort=2181
# 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.186=10.1.44.186:2888:3888
server.187=10.1.44.187:2888:3888
server.188=10.1.44.188:2888:3888　　3.创建所需文件夹
mkdir -p /usr/local/zookeeper/data
mkdir -p /usr/local/zookeeper/log　　4.配置文件传输给其他zookeeper集群节点
scp zoo.cfg　　5.创建myid标识文件(同上面server.186的尾号)
# 186 server
cd /usr/local/zookeeper/data
echo '186' > myid
# 187 server
cd /usr/local/zookeeper/data
echo '187' > myid
# 188 server
cd /usr/local/zookeeper/data
echo '188' > myid　　6.启动
# 186 server
/usr/local/zookeeper/bin/zkServer.sh start
