# 05.CentOS7 Zookeeper安装教程

### 一、下载地址

http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.5.8/apache-zookeeper-3.5.8-bin.tar.gz

### 二、安装

**1. 解压**

```
[hadoop@localhost sources]$ sudo tar -zxf apache-zookeeper-3.5.8-bin.tar.gz -C /usr/local/
```

**2. 修改权限**

```
[hadoop@localhost local]$ sudo chown -R hadoop:hadoop /usr/local/apache-zookeeper-3.5.8-bin/
```

**3.修改配置文件**

+ zoo.cfg

```
[hadoop@localhost apache-zookeeper-3.5.8-bin]$ cd /usr/local/apache-zookeeper-3.5.8-bin/conf/
[hadoop@localhost conf]$ cp zoo_sample.cfg zoo.cfg
[hadoop@localhost conf]$ vim zoo.cfg
[hadoop@localhost apache-zookeeper-3.5.8-bin]$ mkdir -p tmp/zookeeper
```

修改文件

```xml
# The number of milliseconds of each tick
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=/usr/local/apache-zookeeper-3.5.8-bin/tmp/zookeeper
# the port at which the clients will connect
clientPort=2181
# 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
```

**4. 添加环境变量**

```
[hadoop@localhost zookeeper]$ vim ~/.bashrc
```

添加如下内容

```
export ZOOKEEPER_HOME=/usr/local/apache-zookeeper-3.5.8-bin
export PATH=$ZOOKEEPER_HOME/bin:$PATH
```

使配置生效

```
[hadoop@localhost zookeeper]$ source ~/.bashrc 
```

**5. 启动**

```
[hadoop@localhost zookeeper]$ zkServer.sh start
```

**6. 验证**

```
[hadoop@localhost zookeeper]$ zkServer.sh status
```
