1. Use WinSCP to remotely record three servers
2. Use XShell5 to connect to three servers respectively, and use commands to perform remote operations on them
3. Create zookeeper folders under the three servers respectively
mkdir zookeeper
4. Download zookeeper-3.4.10 on three servers respectively (or download on one service, and then copy to the other two), and decompress them. The names are zookeeper-3.4.10_1, ookeeper-3.4.10_2, ookeeper -3.4.10_3
tar -czvf zookeeper-3.4.10.tar.gz ./zookeeper-3.4.10_1
5. Locate the conf path and create the file zoo.cfg
cd zookeeper-3.4.10_1/conf/ (same for the other two)
touch zoo.cfg
6. Create a data folder under zookeeper-3.4.10_1, zookeeper-3.4.10_3, zookeeper-3.4.10_3, and create a logs folder under the data folder
cd ../ (same for the other two)
mkdir data
cd data
mkdir logs
Seven, modify the contents of the three zoo.cfg respectively

1) Modify the paths of dataDir and dataLogDir to actual paths respectively
2) Since the three servers are deployed on different machines, their port numbers clientPort can be set to the same or different.
3) server.X=A:B:C where
X: is a number, indicating which server this is
A: is the IP address where the server is located, write the IP addresses of the three servers respectively
B: Configure the port used by the server to exchange information with the leader in the cluster. Since the three servers are deployed on different machines, they can be set to the same or different
C: Configure the port used to elect the leader. Since the three servers are deployed on different machines, they can be set to the same or different
8. Create myid under the paths of /zookeeper-3.4.10_1/data, /zookeeper-3.4.10_2/data, and /zookeeper-3.4.10_3/data, and write 1, 2, and 3 in the file respectively.
touch myid
9. Enter the /zookeeper-3.4.10_1/bin, /zookeeper-3.4.10_2/bin, and /zookeeper-3.4.10_3/bin directories respectively, and enter the command: ./zkServer.sh start to start the server. Use the ./zkServer.sh status command to view the running status of the three servers. Use the ./zkServer.sh stop command to stop the server from running.
