X.X.2Since 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.当张大栓和赵三等人闻声赶过来，看见大大小小的少年和姑娘，连上丫头们，在萝卜地头围了一大圈，笑嚷声响彻山谷，心下纳闷，挤进人群一看，顿时眼睛瞪得跟铜铃似的——只见小孙子正撅着小屁股，双手攥住一窝萝卜缨——他贪多，觉得一根一根地拔太费事了——咬牙使劲，小脸憋得紫涨，用力往后拽。心理医生罗威与未婚妻姚雨薇因在火锅店外接到一个奇怪电话而逃过火锅店爆炸。免于死亡的他们却身陷随后的一系列奇异死亡事件中。随着罗威一步步的调查揭秘，他发现死亡的源头竟然是自己在一家书店买了一个奇怪的笔记本，当罗威再次陷入诡异爆炸事件中时，他突然醒来，发现自己被困在一间实验室里，更可怕的是他发现自己并不是罗威，所经历的一系列可怕事件，都是关于惩罚和自我救赎的死亡体验。
