export JVMFLAGS="-Xms1024m -Xmx2048m $JVMFLAGS"

vi /export/servers/zookeeper/bin/zkEnv.sh

(修改下面的参数zookeeper.out存储路径)

ZOO_LOG_DIR="/export/log/zookeeper/"

上述操作在三台主机上都执行，或者直接拷贝。

第1机器创建相应文件夹

mkdir /export/data/zookeeper/
mkdir /export/log/zookeeper/
echo "0" > /export/data/zookeeper/myid

第2机器创建相应文件夹

mkdir /export/data/zookeeper/
mkdir /export/log/zookeeper/
echo "1" > /export/data/zookeeper/myid

第3机器创建相应文件夹

mkdir /export/data/zookeeper/
mkdir /export/log/zookeeper/
echo "2" > /export/data/zookeeper/myid

启动方式：

编写zookeeper的启动文件：
