How to manage user permissions of Zookeeper on CentOS
Apr 14, 2025 pm 03:57 PMManaging 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.
