Zookeeper Setup

I. Download Installation Package

Download address: https://zookeeper.apache.org/releases.html

Historical version download address: https://archive.apache.org/dist/zookeeper/

It is recommended to select versions 3.5.8 and above. The 3.8.4 version is used for installation below.

Note

The following commands need to be executed in the Zookeeper installation directory. You can enter the directory by the command cd <Zookeeper installation directory>. On Linux/macOS systems, use the default terminal; on Windows systems, use PowerShell.

II. Installation

(I) Unzip

Use visualization tools or the following commands to unzip:

# Linux/macOS
tar zxvf apache-zookeeper-3.8.4-bin.tar.gz -C <Zookeeper installation directory>

Windows can try the above command. If there is no tar command, use Windows Explorer to unzip.

Prompt

For the convenience of subsequent operations, a soft link can be created for the Zookeeper installation directory.

Create a soft link (optional):

# Linux/macOS
ln -s apache-zookeeper-3.8.4-bin zookeeper

# Windows
New-Item -Path .\zookeeper\ -ItemType SymbolicLink -Target .\apache-zookeeper-3.8.4-bin

(II) Configuration

Create a data storage directory:

# Linux/macOS/Windows
mkdir data

Modify the Zookeeper configuration:

# Linux/macOS
cat > ./conf/zoo.cfg << EOF
tickTime=2000
initLimit=10
syncLimit=5
dataDir=data
clientPort=2181
clientPortAddress=127.0.0.1
autopurge.snapRetainCount=3
autopurge.purgeInterval=1
admin.serverPort=8888
admin.enableServer=false
EOF

# Windows
Set-Content -Path ./conf/zoo.cfg -Value @(
    "tickTime=2000"
    "initLimit=10"
    "syncLimit=5"
    "dataDir=data"
    "clientPort=2181"
    "clientPortAddress=127.0.0.1"
    "autopurge.snapRetainCount=3"
    "autopurge.purgeInterval=1"
    "admin.serverPort=8888"
    "admin.enableServer=false"
)

III. Run

# Linux/macOS
./bin/zkServer.sh start

# Windows
.\bin\zkServer.cmd

IV. Stop

# Linux/macOS
./bin/zkServer.sh stop

# Windows
Close the running terminal
