centos安装zookeeper
安装路径/usr/local/src/project
下载安装
zookeeper.3.6.3
以zookeeper.3.6.2版本为例
wget /apache/zookeeper/zookeeper-3.6.2/apache-zookeeper-3.6.
修改配置文件
[root@centos-linux1 apache-zookeeper-3.6.2]# tar -zxvf apache-zookeeper-3.6.
[root@centos-linux1 apache-zookeeper-3.6.2]# cd conf/
[root@centos-linux1 conf]# cp zoo_sample.cfg
[root@centos-linux1 conf]# ll

[root@centos-linux1 conf]# ll
dataDir=/usr/local/src/program/apache-zookeeper-3.6.2-bin/data
dataLogDir=/usr/local/src/program/apache-zookeeper-3.6.2-bin/logs
启动和停止
bin/ start
启动报错
ZooKeeper JMX enabled by default
Using config: /usr/local/src/program/apache-zookeeper-3.6.2/bin/../conf/
Starting zookeeper ... FAILED TO START
查看日志
Error: Could not find or load main class
原因是需要安装编译好的二进制文件包，重新下载apache-zookeeper-3.6.包安装
重新启动
[root@centos-linux1 apache-zookeeper-3.6.2-bin]# bin/ start
/usr/bin/java
ZooKeeper JMX enabled by default
Using config: /usr/local/src/program/apache-zookeeper-3.6.2-bin/bin/../conf/
Starting zookeeper ... STARTED
停止和重启
bin/ stop
bin/ restart
验证
[root@centos-linux1 apache-zookeeper-3.6.2-bin]# bin/ -server localhost:2181
/usr/bin/java

单机zk集群
1.复制zookeeper根目录，创建zookeeper1，zookeeper2，zookeeper3
2.修改对应的文件
dataDir=/usr/local/src/program/zookeeper3/data
dataLogDir=/usr/local/src/program/zookeeper3/logs
# the port at which the clients will connect
# 端口号修改
clientPort=2183
# 每个节点的文件中都要添加节点server地址
server.1=127.0.0.1:2881:3881
server.2=127.0.0.1:2882:3882
server.3=127.0.0.1:2883:3883
3.分别启动每个节点
