zookeeper安装

安装之前：先关闭三台服务器的防火墙！！！！！

systemctl stop firewalld

systemctl disable firewalld

1)上传 /opt/modules下面

2）解压 /opt/installs下面

tar -zxvf zookeeper-3.4.10.tar.gz -C /opt/installs/

3） 重命名

mv zookeeper-3.4.10/ zookeeper

4）修改配置文件

进入到/opt/installs/zookeeper/conf文件夹下，重命名zoo_sample.cfg

mv  zoo_sample.cfg  zoo.cfg

修改这个配置文件

我的配置文件全部：

# 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/installs/zookeeper/zkData
# 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.1=bigdata01:2888:3888
server.2=bigdata02:2888:3888
server.3=bigdata03:2888:3888

记得在zookeeper中创建zkData文件夹，以及myid文件

配置环境变量：

/etc/profile

刷新一下环境变量：

source /etc/profile

接着配置第二台和第三台：

在bigdata02中，修改myid 为2

bigdata03中，修改myid为3

在每一台电脑上，都启动zkServer

zkServer.sh start
