linux centos Firewall configuration ASD

To safely configure ZooKeeper permissions on CentOS system, you need to follow the following steps:

Step 1: Install ZooKeeper

First, make sure ZooKeeper is installed. If not installed, use the following command to install:

 sudo yum install zookeeper zookeeper-server

Step 2: Configure ZooKeeper

Edit the ZooKeeper configuration file /etc/zookeeper/conf/zoo.cfg to ensure the configuration is correct. The following is an example configuration:

 <code>tickTime=2000 dataDir=/var/lib/zookeeper clientPort=2181 initLimit=5 syncLimit=2 server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888 ``` 請根據(jù)實際情況修改服務(wù)器地址(`server.1`, `server.2`, `server.3`)。 **第三步:創(chuàng)建目錄**創(chuàng)建ZooKeeper數(shù)據(jù)目錄和日志目錄,并設(shè)置權(quán)限: ```bash sudo mkdir -p /var/lib/zookeeper sudo mkdir -p /var/log/zookeeper sudo chown -R zookeeper:zookeeper /var/lib/zookeeper sudo chown -R zookeeper:zookeeper /var/log/zookeeper</code>

Step 4: SELinux configuration (if enabled)

If SELinux is in enforcing mode, you need to configure SELinux policies. It is recommended to temporarily set to permissive mode test first:

 sudo setenforce 0

After the test is successful, create a permanent SELinux policy module:

 sudo ausearch -c 'zookeeper' --raw | audit2allow -M zookeeper_selinux
sudo semodule -i zookeeper_selinux.pp

Step 5: Start the ZooKeeper service

Start the ZooKeeper service and check the status:

 sudo systemctl start zookeeper
sudo systemctl status zookeeper

Step 6: Permission Verification

Verify that the ZooKeeper process can access the data directory and log directory:

 sudo -u zookeeper ls -l /var/lib/zookeeper
sudo -u zookeeper ls -l /var/log/zookeeper

Step 7: Firewall configuration (if enabled)

If you enable the firewall, open the ZooKeeper port (default 2181):

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

Step 8: Log Check

If you have any questions, please check the log file /var/log/zookeeper/zookeeper.out for more information.

Through the above steps, you can safely configure ZooKeeper permissions on the CentOS system. Please be sure to adjust the configuration according to your actual environment, especially the server address and SELinux part.

How to configure Windows 11 firewall to allow PHP services PHP port open and secure settings How to configure Windows 11 firewall to allow PHP services PHP port open and secure settings Jul 23, 2025 pm 06:27 PM

To allow PHP services to pass through the Windows 11 firewall, you need to create inbound rules to open the corresponding port or program. 1. Determine the port that PHP is actually listening. If the built-in server is started with php-Slocalhost:8000, the port is 8000. If using Apache or IIS, it is usually 80 or 443. 2. Open the advanced settings of "WindowsDefender Firewall", create a new inbound rule, select "Program" or "Port", fill in the PHP or Web server path or specify the port number. 3. Select Allow Connections, check the applicable network configuration file, name the rules and add a description. The IP addresses that are allowed to access, such as local network or specific IP, can be restricted through the scope. Safety

Configure CI/CD tools such as GitLabCI, and define the build, test and deployment stages through the .gitlab-ci.yml file to achieve automatic construction, testing and deployment; 3. Integrate test frameworks such as PHPUnit to ensure that tests are automatically run after code changes; 4. Use automated deployment strategies such as Kubernetes to define deployment configuration through the deployment.yaml file; 5. Optimize Dockerfile and adopt multi-stage construction
