安装软件其实主要是配置软件的配置文件。
1、单机安装
先去zookeeper官网下载zookeeper压缩包加压到安装目录。然后修改配置文件。配置文件如下：
# 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=/opt/zookeeper/data #数据路径 需要自己创建 并赋权限
# the port at which the clients will connect
clientPort=2181 #默认zookeeper端口 尽量不改
# 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
dataLogDir=/opt/zookeeper/logs #日志路径 需要自己创建 并赋权限
server.1=localhost:2888:3888 #zookeeper 服务地址 此地是本机。
简单的配置文件配置结束。
然后到zookeeper/bin目录下，运行./zkServer.sh start。因为 zookeeper启动 默认配置文件为conf/zoo.cfg。所以这里注意修改配置文件 zoo_sample.cfg名为 zoo.cfg.
2、集群安装
集群安装就是在 conf末尾添加 其他节点的ip和端口。例如修改 zoo.cfg如下：
# 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=/opt/zookeeper/data #数据路径 需要自己创建 并赋权限
# the port at which the clients will connect
clientPort=2181 #默认zookeeper端口 尽量不改
# 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
dataLogDir=/opt/zookeeper/logs #日志路径 需要自己创建 并赋权限
server.1=ip1:2888:3888
server.2=ip2:2888:3888
server.3=ip3:2888:3888
配置好后将安装包发送到各个目标机器。使用上面命令启动各个机器就ok了。
