环境搭建

1. Ubuntu 14.04.5 LTS

2. zookeeper-3.4.6

3. jdk1.7.0_76

安装

• 下载zookeeper包，由于apache官方网络慢，我们选择从华科大的镜像地址进行下载

wget http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.6/zookeeper-3.4.6.tar.gz

• 解压zookeeper到/usr/local

tar -xzvf zookeeper-3.4.6.tar.gz -C /usr/local
cd /usr/local/zookeeper-3.4.6

• 拷贝一份zookeeper的配置文件，zoo_sample.cfg => zoo.cfg

cd conf
cp zoo_sample.cfg zoo.cfg

• 变更zoo.cfg配置

vi zoo.cfg

主要更改zookeeper的数据存放地址和日志地址

dataDir=/HD/logs/zookeeper
dataLogDir=/HD/logs/zookeeper

# The number of milliseconds of each 
ticktickTime=2000
# The number of ticks that the initial 
# synchronization phase can 
takeinitLimit=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=/HD/logs/zookeeper
dataLogDir=/HD/logs/zookeeper
# 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

• 启动zookeeper

cd ../bin
sh zkServer.sh start //启动
sh zkServer.sh status //检查状态
sh zkServer.sh stop //停止

• 检查zookeeper启动状态

ps -ef|grep zookeeper

遇到的问题

root@127.0.0.1:/usr/local/zookeeper-3.4.6# sh bin/zkServer.sh start
JMX enabled by default
bin/zkServer.sh: 95: /usr/local/zookeeper-3.4.6/bin/zkEnv.sh: Syntax error: "(" unexpected (expecting "fi")

百度得到的答案是Ubuntu的默认shell有问题，把dash改成bash就可以了

root@127.0.0.1:~# cd /bin/
root@127.0.0.1:/bin# ls -l /bin/shlrwxrwxrwx 1 root root 4 Dec 23 22:30 /bin/sh -> dash(默认)
root@127.0.0.1:/bin# ln -sf bash /bin/sh
root@127.0.0.1:/bin# ls -l /bin/shlrwxrwxrwx 1 root root 4 Dec 23 22:37 /bin/sh -> bash
