一.安装jdk环境

1>.操作环境

[root@node101.yinzhengjie.org.cn ~]# cat /etc/redhat-release 
CentOS Linux release 7.6.1810 (Core) 
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# uname -r
3.10.0-957.el7.x86_64
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# uname -m
x86_64
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# cat /etc/hosts | grep yinzhengjie            #注意,本片博客只有3台测试机,每台测试机器必须得配置jdk环境!
172.30.1.101 node101.yinzhengjie.org.cn
172.30.1.102 node102.yinzhengjie.org.cn
172.30.1.103 node103.yinzhengjie.org.cn
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# free -h
              total        used        free      shared  buff/cache   available
Mem:           3.7G        331M        2.9G        9.4M        570M        3.3G
Swap:          2.0G          0B        2.0G
[root@node101.yinzhengjie.org.cn ~]# 

2>.打开Oracle官方网站下载相应的平台的安装包(https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

3>.卸载平台中已经存在的JDK版本 

[root@node101.yinzhengjie.org.cn ~]# java -version
openjdk version "1.8.0_201"
OpenJDK Runtime Environment (build 1.8.0_201-b09)
OpenJDK 64-Bit Server VM (build 25.201-b09, mixed mode)
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# rpm -qa *openjdk*
java-1.7.0-openjdk-headless-1.7.0.191-2.6.15.5.el7.x86_64

java-11-openjdk-11.0.ea.28-7.el7.x86_64
java-1.8.0-openjdk-1.8.0.201.b09-2.el7_6.x86_64
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# rpm -e --nodeps java-1.7.0-openjdk-headless-1.7.0.191-2.6.15.5.el7.x86_64          #卸载JDK版本!
[root@node101.yinzhengjie.org.cn ~]# rpm -e --nodeps java-1.7.0-openjdk-1.7.0.191-2.6.15.5.el7.x86_64
[root@node101.yinzhengjie.org.cn ~]# rpm -e --nodeps java-1.8.0-openjdk-headless-1.8.0.201.b09-2.el7_6.x86_64
[root@node101.yinzhengjie.org.cn ~]# rpm -e --nodeps java-11-openjdk-headless-11.0.ea.28-7.el7.x86_64
[root@node101.yinzhengjie.org.cn ~]# rpm -e --nodeps java-1.8.0-openjdk-devel-1.8.0.201.b09-2.el7_6.x86_64
[root@node101.yinzhengjie.org.cn ~]# rpm -e --nodeps java-11-openjdk-11.0.ea.28-7.el7.x86_64
[root@node101.yinzhengjie.org.cn ~]# rpm -e --nodeps java-1.8.0-openjdk-1.8.0.201.b09-2.el7_6.x86_64
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# rpm -qa *openjdk*
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# java -version
-bash: /usr/bin/java: No such file or directory
[root@node101.yinzhengjie.org.cn ~]#

4>.将下载的jdk版本进行解压安装并配置环境变量(如果你下载的是rpm包的oracle jdk的话就无需配置环境变量啦!)

[root@node101.yinzhengjie.org.cn ~]# mkdir /yinzhengjie/softwares -p
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# tar -zxf jdk-8u201-linux-x64.tar.gz -C /yinzhengjie/softwares/
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# ll /yinzhengjie/softwares/jdk1.8.0_201/

# 滴答,计时的基本单位,默认是2000毫秒,即2秒。它是zookeeper最小的时间单位,用于丈量心跳时间和超时时间等,通常设置成默认2秒即可。
tickTime=2000

# 初始化限制是10滴答,默认是10个滴答,即默认是20秒。指定follower节点初始化是链接leader节点的最大tick次数。
initLimit=5

# 数据同步的时间限制,默认是5个滴答,即默认时间是10秒。设定了follower节点与leader节点进行同步的最大时间。与initLimit类似,它也是以tickTime为单位进行指定的。
syncLimit=2

# 指定zookeeper的工作目录,这是一个非常重要的参数,zookeeper会在内存中在内存只能中保存系统快照,并定期写入该路径指定的文件夹中。生产环境中需要注意该文件夹的磁盘占用情况。
dataDir=/home/yinzhengjie/zookeeper

# 监听zookeeper的默认端口。zookeeper监听客户端链接的端口,一般设置成默认2181即可。
clientPort=2181

# 这个操作将限制连接到 ZooKeeper 的客户端的数量,限制并发连接的数量,它通过 IP 来区分不同的客户端。此配置选项可以用来阻止某些类别的 Dos 攻击。将它设置为 0 或者忽略而不进行设置将会取消对并发连接的限制。
#maxClientCnxns=60
 
# 在上文中已经提到,3.4.0及之后版本,ZK提供了自动清理事务日志和快照文件的功能,这个参数指定了清理频率,单位是小时,需要配置一个1或更大的整数,默认是0,表示不开启自动清理功能。
#autopurge.purgeInterval=1

# 这个参数和上面的参数搭配使用,这个参数指定了需要保留的文件数目。默认是保留3个。
#autopurge.snapRetainCount=3

#server.x=[hostname]:nnnnn[:nnnnn],这里的x是一个数字,与myid文件中的id是一致的。右边可以配置两个端口,第一个端口用于F和L之间的数据同步和其它通信,第二个端口用于Leader选举过程中投票通信。

三.zookeeper客户端四字符指令

  ZooKeeper 支持某些特定的四字命令字母与其的交互。它们大多是查询命令,用来获取 ZooKeeper 服务的当前状态及相关信息。用户在客户端可以通过 telnet 或 nc 向 ZooKeeper 提交相应的命令,接下来我们一起体验一下吧。
