安装 zookeeper

cd zookeeper-3.4.8

cp -r * /zookeeper/server1/

cp -r * /zookeeper/server2/

cp -r * /zookeeper/server3/

 

在之前设置的dataDir中新建myid文件, 写入一个数字, 该数字表示这是第几号server. 该数字必须和zoo.cfg文件中的server.X中的X一一对应.

/zookeeper/server1/data/myid文件中写入1, 

/zookeeper/server2/data/myid文件中写2, 

/zookeeper/server3/data/myid文件中写入3.

redis01:/zookeeper/server1/data# cd /zookeeper/
