一.环境准备

Centos6.5_x86_64

jdk-7u71-linux-x64.rpm

zookeeper-3.4.8.tar.gz

mkdir /zookeeper/data

二.安装、
mkdir -pv /usr/java
[root@zookeeper1 java]# tar zxvf zookeeper-3.4.8.tar.gz
mv zookeeper-3.4.8 zookeeper
cd zookeeper
cd conf
mv zoo_sample.cfg zoo.cfg
vi zoo.cfg

# synchronization phase can take

# 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=/zookeeper/data和dataLogDir=/zookeeper/logs (这个路径是数据路径，自己建立)

这里的server.25是个重点，自己定义，用在myid里。

在/zookeeper/data下

touch myid

echo 25 > myid (三台不一样）

这里用的是IP，如果用主机名的话，就要修改/etc/hosts

如果这里没有这个myid文件或者值不对，就会出现启动报错
