Managing Zookeeper user rights on CentOS usually involves the following aspects:

1. Configure Zookeeper's ACL (Access Control Lists)

Zookeeper supports ACL-based permission management, which can be set through configuration files or command lines.

Setting up ACL via configuration file

Edit the zoo.cfg file, add or modify the following:

 authProvider.1=org.apache.zookeeper.server.auth.SASLAuthenticationProvider
jaasLoginRenew=3600000

Then create a JAAS configuration file (such as zookeeper_jaas.conf) with the following content:

 Server {
    org.apache.zookeeper.server.auth.DigestLoginModule required
    user_super="super_secret_password"
    user_admin="admin_password";
};

Specify the JAAS configuration file path in zoo.cfg:

 jaasLoginPath=/path/to/zookeeper_jaas.conf

Setting the ACL via the command line

After starting Zookeeper, you can use the zkCli.sh script to set the ACL:

 ./zkCli.sh -server localhost:2181
addauth digest username:password
create /path "data" acl

2. Use Zookeeper's command line tool

Zookeeper provides some command line tools to manage users and permissions.

Add a user

 addauth digest username:password

Create node and set up ACL

 create /path "data" acl

View node ACL

 getAcl /path

Modify node ACL

 setAcl /path acl

3. Configure firewalls and security groups

Ensure that the firewall and security group configuration of the Zookeeper server allows necessary port communication (default is 2181).

Firewall configuration

 sudo firewall-cmd --permanent --zone=public --add-port=2181/tcp
sudo firewall-cmd --reload

Security group configuration (if using cloud service)

In the cloud service provider's console, configure security group rules to allow traffic on port 2181.

4. Monitoring and logging

Configure Zookeeper's monitoring and logging to promptly discover and resolve permission-related issues.

Log configuration

Edit the zoo.cfg file to ensure that the log level and log file path are set correctly:

 dataLogDir=/var/log/zookeeper
maxConsoleLogLevel=INFO

Through the above steps, you can effectively manage Zookeeper's user rights on CentOS. Ensure that permission settings are regularly reviewed and updated to keep the system secure.
