What Should I Do If a Service Port Is Used by the Agent?

Constraints

The restoration method in this section only supports new Agent version. If your Agent is of an earlier version, you are advised to upgrade it to the new version.

Run the following command to check the current Agent version:

if [[ -f /usr/local/uniagent/extension/install/telescope/bin/telescope ]]; then /usr/local/uniagent/extension/install/telescope/bin/telescope -v; elif [[ -f /usr/local/telescope/bin/telescope ]]; then echo "old agent"; else echo 0; fi

Procedure

1. Log in to the primary node as a root user.
2. Run the following command to open the sysctl.conf file:

   vim /etc/sysctl.conf

3. (Permanent change) Add new ports to the sysctl.conf file:

   net.ipv4.ip_local_port_range=49152 65536

4. Run the following command to make the change take effect:

   sysctl -p /etc/sysctl.conf

   

   • The modification is permanent and still takes effect after the host is restarted.
   • To make a temporary modification (the password becomes invalid after the host is restarted), run the # echo 49152 65536 > /proc/sys/net/ipv4/ip_local_port_range command.
5. Restart the Agent:
   • Windows:
     • In the directory where the Agent installation package is stored, double-click the shutdown.bat script to stop the Agent, and then execute the start.bat script to start the Agent.
   • Linux:
     • Run the following command to check the PID of telescope:
     • ps -ef |grep telescope
     • After the process is forcibly stopped, wait for 3 to 5 minutes for the Agent to automatically restart. Figure 1 shows an operation example.
     • kill -9 PID
