1. Redis server


First download the Redis server, click to download the .msi version, double-click to install the Redis server, and it will be installed as a service. Start the system together:

How to use Redis cache server under Windows

The first thing after installing the Redis server is to set a password and enter the installation directory: C:\Program Files\Redis - Find the configuration file: redis. windows-service.conf - Find: # requirepass foobared - Enter, line feed and add: requirepass Write your new password here (write it on the top line, without leaving a space in front) - Go to the service and restart the Redis service, or restart the computer

The disadvantages of not setting a password can be understood by looking at what happened to this guy from Ctrip: Remember an incident where Redis was attacked


2. Redis client (command line and Visual tool RDM)

Command line demonstration: start Redis client, read and write Redis server

How to use Redis cache server under Windows

Command explanation in the above picture:

cd C:\Program Files\Redis: The cd command enters the Redis installation directory, which is equivalent to double-clicking to enter the Redis installation directory in Windows.

redis-cli.exe: Opens the redis-cli client program, which is equivalent to Windows Double-click to run an exe program in the system (after installing the above Redis server program, a client program is needed to connect to the server. To connect to the local redis server, type this command directly. To connect to the remote, you need to add the ip and port, for example: redis- cli.exe -h 111.11.11.111 -p 6379)


keys *: View all key-value pairs (if the Redis server has a password set, this command will report an error, need Enter the password first and execute this command: auth your password)

set blog oppoic.cnblogs.com: Set a key-value pair, the key is: blog, the value is: oppoic.cnblogs.com (stored by directory : set directory name: key value)

get blog: Get the value corresponding to the key blog

keys *: View all key-value pairs

Other commonly used commands:

config get dir: Get the redis installation directory

ping: Return PONG to indicate that the redis server is normal

redis-cli.exe: Enter the first database (default), redis has a total of 0 There are 16 libraries in total to 15, enter the third library redis-cli -n 2 (already entered, select 0~15 to switch at will)

quit: Exit the redis program

exit: Exit dos window

flushdb: Delete all keys in the currently selected database

flushall: Delete databases in all databases

More commands: https://redis.io/ commands

At this point, a Redis cache server running on the local machine has been set up and can be read and written. However, the command line is obviously not friendly to novice users. The visualization tool appears: Redis Desktop Manager (https://redisdesktop.com/download)

How to use Redis cache server under Windows

The tree on the left shows that there are already Once connected, click Connect to Redis Server at the bottom to add another connection:

Name: connection name, start as you like

Host: host address, this machine is 127.0.0.1, input remotely Corresponding IP

Port: Port, the Redis server default port is 6379

Auth: password, enter it if set, leave it blank if not set

You can see it after connecting to the Redis server , the default is 16 libraries (the configuration file can be changed), and the index starts from 0. A common usage is to have one project and one library, and different functional modules under the project are stored in different directories under this library.

Needless to say, the operation after having the visualization tool is to double-click, right-click to create, and delete. . . Anyone who knows how to use Windows system will use this tool. Compared with the command line, Redis Desktop Manager is a visual tool that is more user-friendly and more convenient for debugging data on remote servers.

Note: This machine can do this. To connect to the remote server, you need to go to the Redis installation directory on the server, find the redis.windows-service.conf file, find bind 127.0.0.1, add "#" in front of it, comment it out, and then Right-click on the service to restart the redis service, or restart the Windows system

3. C# operating Redis server

The above are all command lines and visual tools to operate Redis server. C# programs need to use StackExchange.Redis(https://github.com/StackExchange/StackExchange.Redis to operate Redis) ), in order to call it uniformly, a RedisHelper helper class is encapsulated:

                    {
                        if (_redis != null) return _redis;

                        _redis = GetManager();
                        return _redis;
                    }
                }
                return _redis;
            }
        }

        private static ConnectionMultiplexer GetManager(string connectionString = null)
        {
            if (string.IsNullOrEmpty(connectionString))

Add a record with the key name and the value wangjie to the fd1 directory of the first library of the redis server:

RedisHelper.StringSet(CacheFolderEnum.Folder1, "name", "wangjie");
Copy after login

Get this record:

string key = RedisHelper.StringGet(CacheFolderEnum.Folder1, "name");
Console.WriteLine("键为name的记录对应的值:" + key);
Copy after login

Delete this record:

bool result = RedisHelper.StringRemove(CacheFolderEnum.Folder1, "name");
if (result)
{
    Console.WriteLine("键为name的记录删除成功");
}
else
{
    Console.WriteLine("键为name的记录删除失败");
}
Copy after login

Query whether this record exists:

bool ifExist = RedisHelper.KeyExists(CacheFolderEnum.Folder1, "name");
if (ifExist)
{
    Console.WriteLine("键为name的记录存在");
}
else
{
    Console.WriteLine("键为name的记录不存在");
}
Copy after login

Go to the fd2 directory of the second library of the redis server , add a record with the key sd1 and the value an object:

Student student = new Student() { Id = 1, Name = "张三", Class = "三年二班" };
RedisHelper.Set<Student>(CacheFolderEnum.Folder2, "sd1", student, 10, 1);
Copy after login

Get this object:

Student sdGet = RedisHelper.Get<Student>(CacheFolderEnum.Folder2, "sd1", 1);
if (sdGet != null)
{
    Console.WriteLine("Id:" + sdGet.Id + " Name:" + sdGet.Name + " Class:" + sdGet.Class);
}
else
{
    Console.WriteLine("找不到键为sd1的记录");
}
Copy after login

The environment is VS 2013. If it cannot run, copy the code in cs and compile and run it yourself


4. Others

MSOpenTech developed the Redis cache server with built-in persistence. After writing, the key-value pair will still exist when the computer is restarted. Generally, the expiration time must be set for writing the key-value pair, otherwise the memory occupied will not be released. Redis storage method not only has keys corresponding to strings, but also corresponds to List, HashTable, etc. Of course, more advanced uses of Redis are still under Linux.

Laravel8 optimization points Laravel8 optimization points Apr 18, 2025 pm 12:24 PM

Laravel 8 provides the following options for performance optimization: Cache configuration: Use Redis to cache drivers, cache facades, cache views, and page snippets. Database optimization: establish indexing, use query scope, and use Eloquent relationships. JavaScript and CSS optimization: Use version control, merge and shrink assets, use CDN. Code optimization: Use Composer installation package, use Laravel helper functions, and follow PSR standards. Monitoring and analysis: Use Laravel Scout, use Telescope, monitor application metrics.

In Laravel development, dealing with complex model relationships has always been a challenge, especially when it comes to multi-level BelongsToThrough relationships. Recently, I encountered this problem in a project dealing with a multi-level model relationship, where traditional HasManyThrough relationships fail to meet the needs, resulting in data queries becoming complex and inefficient. After some exploration, I found the library staudenmeir/belongs-to-through, which easily installed and solved my troubles through Composer.

Redis plays a key role in data storage and management, and has become the core of modern applications through its multiple data structures and persistence mechanisms. 1) Redis supports data structures such as strings, lists, collections, ordered collections and hash tables, and is suitable for cache and complex business logic. 2) Through two persistence methods, RDB and AOF, Redis ensures reliable storage and rapid recovery of data.
