Zookeeper fully distributed installation step tutorial

1. Three nodes need to install JDK
2. Three nodes need to close the firewall
   service iptables stop
   chkconfig iptables off
3. The first server enters the software directory
   cd /home/software/
4. Delete the stand-alone mode of Zookeeper
   rm -rf zookeeper-3.4.8
5. Turn off Zookeeper's stand-alone mode.
   View through jps, find QuorumPeerMain, and then kill -9 process number
6. Re-extract
   tar -xvf zookeeper-3.4.8.tar.gz
7. Enter
   cd zookeeper-3.4.8/conf in the subdirectory conf
8. Copy
   cp zoo_sample.cfg zoo.cfg
9. Edit
   vim zoo.cfg to
   modify the dataDir attribute
   dataDir=/home/software/zookeeper-3.4.8/tmp and
   add
   server at the end of the file . Number = IP or host name: port number 1: port number 2,
   for example
   server.1=10.9.162.133 :2888:3888
   server.2=10.9.152.65:2888:3888
   server.3=10.9.130.83:2888:3888
10. Create a new data directory and enter
    cd…
    mkdir tmp
    cd tmp
11. Edit
    vim myid
    to add the number given by the current cloud host to the file, for example, the number 1 given by the first cloud host
12. Remote copy
    cd /home/software/
    scp -r zookeeper-3.4.8 [email protected]: $PWDscp-rzookeeper-3.4.8root@10.9.130.83:$ PWD
    cloud host password: tarena2017Up;
13. Modify the myid of the other two cloud hosts
    cd /home/software/zookeeper-3.4.8/tmp
    vim myid
    to change the number to the number corresponding to the current cloud host
14. Start Zookeeper
    cd /home/software/zookeeper-3.4.8/bin
    sh zkServer.sh start
15. Check the status of the Zookeeper node
    sh zkServer.sh status
    If there is 1 leader+2 followers, it means the startup is successful
