Redis default configuration is very simple, port, storage log and path, password setting, storage policy and so on. There are many references for specific settings on the Internet.

Port 6379

Dbfilename dump.rdb

Dir d:\ redis

Requirepass redis@123

Maxclients 10000: 10000 clients by default. When you cannot set the process file handle limit, redis will be set to the current file handle limit minus 32, because redis will leave some handles for its internal processing logic.

If this limit is reached, redis rejects new connection requests and sends a "max number of clients reached" to those connection requesters in response.

Maxmemory:

Sets the amount of memory that redis can use. Once the memory usage limit is reached, redis will attempt to remove internal data, and removal rules can be specified through maxmemory-policy.

If redis cannot remove data from memory according to the removal rule, or if we set "do not allow removal", then redis will return an error message for instructions that need to request memory, such as SET, LPUSH, and so on. However, instructions with no memory requests will still respond normally, such as GET, etc.

It is important to note that if your redis is the master redis (indicating that your redis has a slave redis), then when setting the upper limit of memory usage, you need to set some memory space in the system for the synchronization queue cache, and only if you set it to "do not remove", do not consider this factor.

For memory removal rules, redis provides up to six removal rules. They are:

1.volatile-lru: use the LRU algorithm to remove key from expired collections

2.allkeys-lru: remove key using the LRU algorithm

3.volatile-random: removes random key from expired collections

4.allkeys-random: remove random key

5.volatile-ttl: remove the key with the lowest TTL value, that is, the key that has only recently expired.

6.noeviction: no removal. For write operations, only error messages are returned.

Whichever of the above removal rules is used, redis returns an error message for the write request if there is no appropriate key to remove.

Many times this setting will leave a huge hole after a long time.

Enter redis:

A normal startup displays the following message:

Sometimes a 1067 error will be reported when the windows system service redis is added, and the re-registration service can be deleted. Most of the system will start normally after the system restart.
