[root@q zk1]# cp -rf zookeeper-3.4.6 /home/zsq/tools/zk2
[root@q zk1]# cp -rf zookeeper-3.4.6 /home/zsq/tools/zk3

修改zk2和zk3

[root@q dataDir]# pwd

[root@q dataDir]# cat myid

[root@q dataDir]# pwd

启动 zk1 zk2 zk3

[root@q zookeeper-3.4.6]# cd bin/
[root@q bin]# ls   # zkServer.cmd是windows下的运行程序
README.txt  zkCleanup.sh  zkCli.cmd  zkCli.sh  zkEnv.cmd  zkEnv.sh  zkServer.cmd  zkServer.sh
[root@q bin]# ./zkServer.sh start  #启动
JMX enabled by default
Using config: /home/zsq/tools/zk1/zookeeper-3.4.6/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

启动完成会在目录下生成zookeeper.out

[root@q bin]# cat 
README.txt     zkCleanup.sh   zkCli.cmd      zkCli.sh       zkEnv.cmd      zkEnv.sh       zkServer.cmd   zkServer.sh    zookeeper.out

相应的命令启动另外两台，进入到相应的路径

[root@q zookeeper-3.4.6]# netstat -ntpl|grep "218"
tcp        0      0 :::2181                     :::*                        LISTEN      5727/java           
tcp        0      0 :::2182                     :::*                        LISTEN      5673/java           
tcp        0      0 :::2183                     :::*                        LISTEN      5640/java

连接测试，能连进去就表面OK

[root@q bin]# ./zkCli.sh -server 127.0.0.1:2181
