解决 K8s 部署 MySQL 集群 StatefulSet 时报错: 'ncat: not found'

The error message indicates that the command 'ncat' is not found in the system.

'ncat' is a tool used for network connections and it seems to be missing in your environment.

To resolve this issue, you can install 'ncat' by following the steps below:

1. Connect to the node where the MySQL StatefulSet is deployed.

2. Run the following command to install 'ncat':

   • For CentOS/RHEL:

     sudo yum install nmap-ncat
     

   • For Ubuntu/Debian:

     sudo apt-get install nmap
     

3. After installing 'ncat', verify its installation:

   ncat --version
   

   This command should display the version information of 'ncat' if it is installed correctly.

Once 'ncat' is installed, try deploying the StatefulSet again and check if the issue is resolved.
