zookeeper注册中心安装（单机版）

下载zookeeper-3.4.9.tar.gz

wget http://apache.fayea.com/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz

解压到 /home/目录下：

cd /home/zookeeper-3.4.9

在/home/zookeeper-3.4.9目录下创建以下目录：

mkdir data

mkdir logs

将/home/zookeeper-3.4.9/conf/下的zoo.sample.cfg 文件拷贝一份，命名为zoo.cfg

cp zoo_sample.cfg zoo.cfg

修改zoo.cfg的配置文件：

vi 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=/tmp/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

其他默认，dataDir修改成刚才新建的data目录，同时新增dataLogDir:

dataDir=/home/zookeeper-3.4.9/data

dataLogDir=/home/zookeeper-3.4.9/logs

保存，单机版配置已经完成。

vi /root/.bash_profile

# zookeeper env
export ZOOKEEPER_HOME=/home/zookeeper-3.4.9
export PATH=$ZOOKEEPER_HOME/bin:$PATH

source /root/.bash_profile

启动zk：

sh /home/zookeeper-3.4.9/bin/zkServer.sh start

jps:

sh zkServer.sh status

开机启动：

在/etc/rc.local文件中追加：

# java_home
export JAVA_HOME=/opt/java/jdk1.7.0_75
# zookeeper
/home/zookeeper-3.4.9/bin/zkServer.sh start

以上即可开机自动启动！！

（带用户：- user -c '/home/zookeeper-3.4.9/bin/zkServer.sh start'）
