Clearing System Logs

Delete log files and historical records, and stop the ECS.

1. Run the following commands to delete redundant key files:

   echo > /$path/$to/$root/.ssh/authorized_keys

   An example command is echo > /root/.ssh/authorized_keys.

   echo > /$path/$to/$none-root/.ssh/authorized_keys

   An example command is echo > /home/linux/.ssh/authorized_keys.

2. Run the following command to clear log files in the /var/log directory:

   rm -rf /var/log/*

   

   Before deleting log files, back up log directories and log files required by application startup. For example, if the default Nginx log directory /var/log/nginx is deleted, Nginx may fail to be started.

3. Run the following commands to delete historical records:

   echo > /root/.bash_history

   history -c
