创建日志目录和数据存放的目录
[root@q zookeeper-3.4.6]# mkdir dataDir dataLogDir [root@q zookeeper-3.4.6]# cd dataDir/ [root@q dataDir]# touch myid #创建一个myid的文件 [root@q dataDir]# echo "1" >> myid #编号为1 [root@q dataDir]# cd ..

修改zk2和zk3
[root@q dataDir]# pwd /home/zsq/tools/zk2/zookeeper-3.4.6/dataDir [root@q dataDir]# cat myid 2 dataDir=/home/zsq/tools/zk2/zookeeper-3.4.6/dataDir dataLogDir=/home/zsq/tools/zk2/zookeeper-3.4.6/dataLogDir # the port at which the clients will connect clientPort=2182 server.1=127.0.0.1:8880:7770 server.2=127.0.0.1:8881:7771 server.3=127.0.0.1:8882:7772 [root@q dataDir]# pwd /home/zsq/tools/zk3/zookeeper-3.4.6/dataDir [root@q dataDir]# cat myid 3 dataDir=/home/zsq/tools/zk3/zookeeper-3.4.6/dataDir dataLogDir=/home/zsq/tools/zk3/zookeeper-3.4.6/dataLogDir # the port at which the clients will connect clientPort=2183 server.1=127.0.0.1:8880:7770 server.2=127.0.0.1:8881:7771 server.3=127.0.0.1:8882:7772
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
