1.选择zookeeper文件夹
安装的时候选择的是/usr/local目录，根据个人情况而定
2.下载zookeeper文件压缩包
wget https://archive.apache.org/dist/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz
3.解压压缩包到当前目录
tar -zxvf zookeeper-3.4.9.tar.gz
4.重命名目录文件（可以不改）
mv zookeeper-3.4.9\ zookeeper
5.复制zookeeper配置文件并重命名zoo.cfg
cd zookeeper/conf/
cp zoo_sample.cfg zoo.cfg
6.修改zoo.cfg文件
vim zoo.cfg
# The number of milliseconds of each tick
# zookeeper 定义的基准时间间隔，单位：毫秒
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
# 数据文件夹
dataDir=/usr/local/zookeeper/data
# 日志文件夹
dataLogDir=/usr/local/zookeeper/logs
# the port at which the clients will connect
# 客户端访问 zookeeper 的端口号
clientPort=2181
# 下面可以增加集群配置
# 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
:wq保存退出
7.增加zookeeper环境变量
#修改环境变量文件 vim /etc/profile #后面增加zookeeper变量 export ZOOKEEPER_INSTALL=/usr/local/zookeeper/ export PATH=$PATH:$ZOOKEEPER_INSTALL/bin export PATH
:wq保存退出
8.使环境变量生效
source /etc/profile
9.启动zookeeper服务
cd /usr/local/bin
#启动服务器
./skServer.sh start
10.查询zookeeper服务
zkServer.sh status
11.查询zookeeper进程
jps
其中QuorumPeerMain是属于zookeeper的进程，表示zookeeper服务已经正常启动
12.安装过程中的出现的问题
12.1出现启动成功，但是进程没有启动
./zkServer.sh start-foreground #启动过程中加入参数详细输出
提示找不到class org.apache.zookeeper.server.quorum.QuorumPeerMain类方法
zookeeper启动需要依赖java环境，将java环境添加到/etc/profile文件内
echo $JAVA_HOME
出现java版本说明java环境正常，如果还存在找不到类方法就重新下载一个zookeeper版本
