C#redis Installation and use

Redis is a widely used Key/value memory database and one of the fastest key-value distributed caches.

One, Redis installation

Select a version to download, the package includes 32-bit and 64-bit installation tools, or directly using the installation version of the installation, is the same, the use of the installation version, the installation results

A Redis server system service will appear in the system service after the installation is complete.

Redis-server.exe: The server's daemon startup program.

Redis.conf: Configuration file.

Redis-cli.exe: Command line client.

Redis-check-dump.exe: Local Database check

Redis-check-aof.exe: Update log check

Redis-benchmark.exe: Performance testing tool to test the read and write performance of Redis in your system and in your configuration.

Second, Redis configuration

1. Port port number, for example 6379

2. Bind instance binding access address 127.0.0.1

3. Password for requirepass access

4. Maxheap Remember to open this configuration node and the Redis service will not start. For example Maxheap 1024000000

5. Timeout: Request time-out

6. logfile:log File Location

7. Databases: Number of open databases

8. Dbfilename: Data Snapshot file name (only file name, excluding directory)

Third, Redis use

Locate the Redis-cli.exe file in the Redis installation directory, and double-click to start it:

Test OK, this is the end of the Redis installation, followed by the actual use in C #.

Second, Redis combat

1. Build the project and refer to the four class libraries associated with Servicestack.redis.

2. Configuration files

<!--Redis Start-to-<add key="sessionexpireminutes"Value=" the"/> <add key="redis_server_session"Value="127.0.0.1:6379"/> <add key="Redis_max_read_pool"Value="3"/> <add key="Redis_max_write_pool"Value="1"/> <!--Redis end-->

3. Create a common class for Redis operations Rediscachehelper

usingServicestack.redis;usingSystem;usingSystem.Collections.Generic;usingSystem.Configuration;usingSystem.Linq;usingSystem.Text;usingSystem.Threading.Tasks;namespaceconsoleapplication{classRediscachehelper {Private Static ReadOnlyPooledredisclientmanager pool =NULL; Private Static ReadOnly string[] redishosts =NULL;  Public Static intRedismaxreadpool =int.

Format ("{0}:{1} has an exception! {2}","Cache","Get", key); }            returnobj; }         Public Static voidRemove (stringkey) {            Try            {                if(Pool! =NULL)                {                    using(varR =pool. Getclient ()) {if(r! =NULL) {R.sendtimeout= +;                        R.remove (key); }                    }                }            }            Catch(Exception ex) {stringmsg =string.
