【zookeeper】简单安装
1.关闭防火墙systemctl stop firewalld.service
systemctl disable firewalld.service
2.安装java
# 卸载已有的jdk
java -version
rpm -qa |grep jdk
yum -y remove java
# 安装同一版本的jdk
rz (jdk-8u144-linux-x64.rpm)
rpm-ivh jdk-8u144-linux-x64.rpm
java -version 3.安装zookeeper
下载地址 : http://zookeeper.apache.org/releases.html
tar zxvf zookeeper-3.4.10.tar.gz
mvzookeeper-3.4.10 /usr/local/zookeeper
cd /usr/local/zookeeper
mkdir data
cd /usr/local/zookeeper/conf
cp -a zoo_sample.cfg zoo.cfg
vim zoo.cfg
----------------
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/usr/local/zookeeper/data
clientPort=2181
----------------
/usr/local/zookeeper/bin/zkServer.sh stop# 停止ZooKeeper服务器
/usr/local/zookeeper/bin/zkServer.sh start# 启动ZooKeeper服务器
----------------
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
---------------- 4.zookeeper客户端的使用(zkCli.sh)
/usr/local/zookeeper/bin/zkCli.sh # 直接进入localhost
/usr/local/zookeeper/bin/zkCli.sh -server 127.0.0.1:2181# -server设定进入那个zookeeper
# zookeeper里面都是绝对路径，没有相对路径
ls / # ls / 查看下初始化后的根目录
