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.该剧讲述了家庭主妇苟吉祥因为追查丈夫死因还自己清白，加入巡捕房。遇到了傲慢公子毛儒毅等侦探，从此主妇励志大翻身，不仅侦破一个个悬疑案件，还收获了爱情。这话把赵耘和杨简之听傻了。他们已经不是光凭热血和激情行事的少年了，多年战场和朝堂的经历，使得他们这次面对紫茄的被掳，并没有被愤怒冲昏头脑，从而失去理智。In this way, through the call to the Bridge class, the call to the implementation classes SourceSub1 and SourceSub2 of the interface Sourceable is realized.
