引言
好久没有安装这些东西,在此处记录一下
========================教程开始======================
1、获取安装包
[root@jack soft]# wget http://archive.apache.org/dist/zookeeper/zookeeper-3.4.10/zookeeper-3.
2、解压
[root@jack soft]# tar -zxvf zookeeper-3.4.10.tar.gz
3、在安装路径下面创建文件夹
[root@jack soft]# mkdir zookeeper-3.4.10
4、将解压文件移动到安装目录下面
[root@jack soft]# mv zookeeper-3.4.10 /data/app/zookeeper-3.4.10/zookeeper1
5、在zk1下面创建文件夹data
mkdir /data/app/zookeeper-3.4.10/zookeeper1/data
6、创建 识别文件
在目录/data/app/zookeeper-3.4.10/zookeeper1/data下创建标识文件myid,在 myid 文件中设置标识(数字),在配置文件中要用到,集群中各个节点不能重 复
echo 1 > myid
7、修改配置文件
主要配置文件位置在:/data/app/zookeeper-3.4.10/zookeeper1/conf
复制出一个 配置文件 cp zoo_sample.cfg zoo.cfg,然后修改配置文件中的内容,下面是我项目中用到的配置文件
# 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=/data/app/zookeeper-3.4.10/zookeeper1/data # 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 server.1=1.2.6.1:2881:3881 server.2=1.2.6.1:2882:3882 server.3=1.2.6.1:2883:3883
8、修改日志配置文件
日志配置文件位置在:/data/app/zookeeper-3.4.10/zookeeper1/conf 路径下log4j.properties
主要修改下面这几个配置项
zookeeper.root.logger=INFO, CONSOLE zookeeper.console.threshold=INFO zookeeper.log.dir=/data/logs/zookeeper zookeeper.log.file=zookeeper.log zookeeper.log.threshold=DEBUG zookeeper.tracelog.dir=/data/logs/zookeeper zookeeper.tracelog.file=zookeeper_trace.log
9、启动服务
/data/app/zookeeper-3.4.10/zookeeper1/bin/zkServer.sh start
10、配置 节点2 和 节点3
同理配置zookeeper2和zookeeper3,其中myid不同,zoo.cfg中的clientPort值不同,修改配置文件 中的端口。
至此,整个 集群的安装完成
附录:zk配置文件的主要配置项介绍
#节点数据、日志路径 dataDir=/opt/zookeeper/zk1/data #dataLogDir=/opt/zookeeper-3.4.10/zk1/logs # 服务器与客户端之间交互的基本时间单元(ms) tickTime=2000 # zookeeper所能接受的客户端数量 initLimit=10 # Leader服务器与follower服务器之间信息同步允许的最大时间间隔,如果超过次间隔,默认follower服务器与leader服务器之间断开链接 syncLimit=5 #节点监听端口 clientPort=2181 #集群中各个节点地址和监听端口 server.1=zk1.jack.com:2881:3881 server.2= zk2.jack.com:2882:3882 server.3= zk3.jack.com:2883:3883 #限制连接到zookeeper服务器客户端的数量 #maxClientCnxns=60
