Since both Redis servers are installed on the Linux operating system, and the two Redis servers will switch when the Master master server fails, it must be ensured that the port numbers of the two Redis servers have been added to the firewall, or the firewalls of the two Linux operating systems have been shut down, otherwise Master-link-Status: down will be prompted, and Master master server is not connected. There are two solutions: the first is to shut down the firewalls of the two Linux operating systems; The second method is to add the port number of each Redis service to the firewall to allow communication through the port number. You can use the command "firewall-cmd-query-port=6379/tcp" first. If the result is No, you can continue to execute the following command "firewall-cmd-add-port=6379/tcp". After the command is executed, you will return Success, indicating that the increase was successful. In this way, Redis servers on the two Linux systems can be switched smoothly to perform sentinel mode operations.And then threw it in the heart of the Sahara Desert,In Wenchuan, Huang Weiping found that those people he was eager to "rescue" did not need him at all at present.
