### 附：1）[Linux Centos7.5 安装配置Oracle jdk1.8，亲测成功][Linux Centos7.5 _Oracle jdk1.8] ###

### **        2）****[zookeeper下载][zookeeper]** ###

**ps: 从目前的最新版本3.5.5开始，带有bin名称的包才是我们想要的下载可以直接使用的里面有编译后的二进制的包，而之前的普通的tar.gz的包里面是只是源码的包无法直接使用。**

**1、下载zookeeper安装包**

**ps:安装包地址随着版本升级，官网这个安装包地址可能就没有了，官网找到自己想安装的版本，安装方法类似。**

**(1)wget https://www-us.apache.org/dist/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz**

**(2)wget --no-check-certificate  https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.14/zookeeper-3.4.14.tar.gz**

**2、解压**

**tar -zxvf   zookeeper-3.4.10.tar.gz**

**3、重命名**

**mv zookeeper-3.4.10/ zookeeper**

**4、编辑profile配置文件**

**  vim /etc/profile **

**由于我安装了jdk,所以这里的配置文件内容是：**

export JAVA_HOME="/opt/jdk1.8.0_191"
    export ZOOKEEPER_HOME="/usr/local/lucifer/zookeeper"
    export CLASSPATH=".:$JAVA_HOME/lib"
    export PATH="$JAVA_HOME/bin:$PATH"
    export PATH="$ZOOKEEPER_HOME/bin:$JAVA_HOME/bin:$PATH"

**source /etc/profile  让配置文件生效；**

**5、将zoo\_sample.cfg复制一份，并且重命名zoo.cfg**

**6、vim zoo.cfg**

dataDir=/usr/local/lucifer/zookeeper/dataDir  
**dataLogDir=/usr/local/lucifer/zookeeper/dataLogDir**

**7、创建dataDir（必须配置，默认是临时文件夹，官方不赞成临时文件夹）和dataLogDir（存放日志）文件夹**

**8、启动**

**执行.zkServer.sh，会显示zookeeper的各种命令：**

**./zkServer.sh start 启动**

**./zkServer.sh stop 停止**

**.zkServer.sh restart重启**

## 注： ##

**如果在执行./zkServer.sh status命令，出现下面问题，或者./zkServer.sh start命令没有报错，但是找不到进程，则看下面解决方案：**

**报错：Error contacting service. It is probably not running.**

**1)首先执行netstat -an | grep 2181，查看2181端口是否被占用，如果如图：**

**执行netstat -nap，查看所有进程，找到2181端口的进程，如果不是zookeeper的，给干掉。**

**kill 进程号**

**可以参考我的另一篇博客：[端口被占用，解决办法][Link 1]**

**2)查看zoo.cfg的配置文件中设置的dataDir,dataLogDir两个路径是否正确，两个文件夹是否创建了。**

### 如果都没有问题，再启动zookeeper试试。 ###

### ps: ###

**     网上说Error contacting service. It is probably not running.这个问题跟防火墙有没有关闭有关系，那我试了下，我原本防火墙是处于关闭状态的，那么我开启试试，结果发现，报上面的错误跟防火墙毛关系都没有。**
