zookeeper安装

本文下载稳定版：zookeeper-3.4.10.tar.gz

  • 下载
[root@yyp softpackages]# wget http://apache.mirrors.lucidnetworks.net/zookeeper/stable/zookeeper-3.4.10.tar.gz
  • 模拟集群
    • 新建一个zookeeper文件夹
    • 在zookeeper文件加下新建server1、server2、server3三个文件夹模拟3台服务器
    • 每个server下新建文件夹data、dataLog、logs
[root@yyp install]# mkdir zookeeper
[root@yyp install]# cd zookeeper/
[root@yyp zookeeper]# mkdir server1 server2 server3
[root@yyp zookeeper]# ll
total 0
drwxr-xr-x. 2 root root 6 Jul 15 11:07 server1
drwxr-xr-x. 2 root root 6 Jul 15 11:07 server2
drwxr-xr-x. 2 root root 6 Jul 15 11:07 server3
[root@yyp zookeeper]#
  • 按以下方式分别解压zookeeper-3.4.10.tar.gz到server1、server2、server3
[root@yyp softpackages]# tar zxvf zookeeper-3.4.10.tar.gz -C /usr/local/install/zookeeper/server1/
  • 每个server文件夹结构如下：
[root@yyp server1]# ll
total 4
drwxr-xr-x.  2 root   root      6 Jul 15 11:23 data
drwxr-xr-x.  2 root   root      6 Jul 15 11:23 dataLog
drwxr-xr-x.  2 root   root      6 Jul 15 11:23 logs
drwxr-xr-x. 10 esuser esuser 4096 Mar 23 07:28 zookeeper-3.4.10
[root@yyp server1]#

配置

  • 进入data目录，创建一个myid的文件，里面写入一个数字（vi myid）
    • server1，myid文件写入一个1
    • server2，myid文件写入一个2
    • server3，myid文件写入一个3
  • 配置server1

进入zookeeper-3.4.10/conf/目录

[root@yyp server1]# cd zookeeper-3.4.10/conf/
[root@yyp conf]# ll
total 12
-rw-rw-r--. 1 esuser esuser  535 Mar 23 06:14 configuration.xsl
-rw-rw-r--. 1 esuser esuser 2161 Mar 23 06:14 log4j.properties
-rw-rw-r--. 1 esuser esuser  922 Mar 23 06:14 zoo_sample.cfg
[root@yyp conf]#

创建一个zoo.cfg的配置文件,并修改配置：

## 创建zoo.cfg
[root@yyp conf]# cp zoo_sample.cfg zoo.cfg
## 编辑
[root@yyp conf]# vi zoo.cfg

修改dataDir(增加dataLogDir)

# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/usr/local/install/zookeeper/server1/data
dataLogDir=/usr/local/install/zookeeper/server1/dataLog/

修改客户端端口

clientPort=2181

在末尾加入

server.1=192.168.74.129:2888:3888
server.2=192.168.74.129:2889:3889
server.3=192.168.74.129:2890:3890
  • server.X 这个数字就是对应 data/myid中的数字。你在3个server的myid文件中分别写入了1，2，3，那么每个server中的zoo.cfg都配server.1,server.2,server.3就OK了。
  • 因为在同一台机器上，后面连着的2个端口3个server都不要一样，否则端口冲突，其中第一个端口用来集群成员的信息交换，第二个端口是在leader挂掉时专门用来进行选举leader所用。
  • 最终zoo.cfg配置如下：
# 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/install/zookeeper/server1/data
dataLogDir=/usr/local/install/zookeeper/server1/dataLog
# 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=192.168.74.129:2888:3888
server.2=192.168.74.129:2889:3889
server.3=192.168.74.129:2890:3890
  • 按上面方法配置server2、server3。因为在同一台服务器上模拟，所以clientPort要不一样
    • server2的配置参数：
      • dataDir=/usr/local/install/zookeeper/server2/data
      • dataLogDir=/usr/local/install/zookeeper/server2/dataLog
      • clientPort=2182
    • server3的配置参数：
      • dataDir=/usr/local/install/zookeeper/server3/data
      • dataLogDir=/usr/local/install/zookeeper/server3/dataLog
      • clientPort=2183
    • server2、server3底部都配置
      • server.1=192.168.74.129:2888:3888
      • server.2=192.168.74.129:2889:3889
      • server.3=192.168.74.129:2890:3890

接入客户端

  • 进入任意server，比如进入server1
[root@yyp bin]# cd /usr/local/install/zookeeper/server1/zookeeper-3.4.10/bin
  • 启动客户端(./zkCli.sh -server 192.168.74.129:2181) ## 2181是server1配置的clientPort
[root@yyp bin]# ./zkCli.sh -server 192.168.74.129:2181
Connecting to 192.168.74.129:2181

[root@yyp bin]# ./zkCli.sh -server 192.168.74.129:2181
