Note: server.1 server.2 server.3 refers to three machines
Two directories created manually
dataDir = / Home / Hadoop / ZooKeeper-3.4.14 / Data
dataLogDir = / Home / Hadoop / ZooKeeper-3.4.14 / log
Creating java.env conf directory
vi
java.env
export JVMFLAGS="-Xms100m -Xmx300m $JVMFLAGS"
Each set of id zoomkeeper
echo "1" > /home/hadoop/zookeeper-3.4.14/data/myid
After doing the above configuration, the other two machines to copy the entire directory on the remote zookeeper's
scp -r /home/hadoop/zookeeper-3.4.14 hadoop @ slave1: / Home / hadoop /
scp -r / Home / haddop / zookeeper- 3.4.14 hadoop @ slave2: / home / hadoop /
and content data / myid is from 2 (server 2) or 3 (seerver 3)
a start command
zookeeper-3.4.14 / bin / zkServer.sh start log will start generating a directory zookeeper.out
view the status of the command
zookeeper-3.4.14 / bin / zkServer.sh status
