*** FATAL CONFIG FILE ERROR ***
Reading the configuration file, at line 194
>>> 'always-show-logo yes'
Bad directive or wrong number of arguments
Cause analysis:
Error means that the specified configuration file directory is wrong or the number of parameters in the configuration file is wrong
the reason is that redis-4.0 is installed for the first time At 8:00, the environment variable is written. When redis server is executed, it will first query whether this instruction is configured in the environment variable,
it is found that there is (or the old 4.0.8) However, the configuration file used is 5.0 To sum up, the redis server in the environment variable is imported from my previous version. If I change the version of redis, I can’t use the previously imported environment variable to execute
Solution:
From this point of view, the solution is clear:
method 1: re import the redis server of the new version of redis to the environment variable
method 2: directly use the redis server in the new version of redis to execute the startup command
Finally, let’s see the situation after the solution
