官网下载地址:http://www.apache.org/dyn/closer.cgi/zookeeper
wget http://mirror.olnevhost.net/pub/apache/zookeeper/zookeeper-3.4.11/zookeeper-3.4.11.tar.gz
tar zxvf zookeeper-3.4.11.tar.gz
mv zookeeper-3.4.11 /usr/local/zookeeper
编辑 /etc/profile 文件, 在文件末尾添加以下环境变量配置:
# ZooKeeper Env
export ZOOKEEPER_HOME=/usr/local/zookeeper
export PATH=$PATH:$ZOOKEEPER_HOME/bin
运行以下命令使环境变量生效:
source /etc/profile
初次使用 ZooKeeper 时,需要将$ZOOKEEPER_HOME/conf 目录下的 zoo_sample.cfg 重命名为 zoo.cfg, zoo.cfg
mv $ZOOKEEPER_HOME/conf/zoo_sample.cfg $ZOOKEEPER_HOME/conf/zoo.cfg
创建目录/usr/local/zookeeper/data
和/usr/local/zookeeper/logs
修改配置文件
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/usr/local/zookeeper/data
dataLogDir=/usr/local/zookeeper/logs
clientPort=2181
如果是多节点,配置文件中尾部增加
server.1=192.168.1.110:2888:3888
server.2=192.168.1.111:2888:3888
server.3=192.168.1.112:2888:3888
同时,增加
#master
echo "1">/usr/local/zookeeper/data/myid
#slave1
echo "2">/usr/local/zookeeper/data/myid
#slave2
echo "3">/usr/local/zookeeper/data/myid
# cd /usr/local/zookeeper/zookeeper-3.4.11/bin
# ./zkServer.sh start

服务启动完成后,可以使用 telnet 和 stat 命令验证服务器启动是否正常:
# telnet 127.0.0.1 2181
