Redis installation/Ubuntu18.04

Introduction of Redis

Redis is an open source (BSD licensed) in-memory data structure stored as a database, cache and message broker. Redis provides data structures such as strings, hashes, lists, collections, sorted collections with range queries, bitmaps, hyperlogs, geospatial indexes, and streams. Redis has built-in replication, Lua scripting, LRU eviction, transactions and different levels of disk persistence, and provides high availability through automatic partitioning of The Redis Sentinel and Redis Cluster.

Official Installation Tutorial

Compile environment Installation

Redis is written in C/C++, so compiling from source to executable requires a C/C++ compiler and a Make toolchain

Compile the installation

Root @ DESKTOP: / usr/local/SRC/REDIS# ls redis - 6.2.3. Tar. Gz root @ DESKTOP: / usr/local/SRC/REDIS# tar XVF - redis - 6.2.3. Tar. Gz Root @ # decompression DESKTOP: / usr/local/SRC/REDIS# redis - 6.2.3 / root @ DESKTOP: CD/usr/local/SRC/redis/redis - 6.2.3 # make # compiling redis Root @ DESKTOP: / usr/local/SRC/REDIS/REDIS - 6.2.3 # make install REDIS server REDIS - cli # REDIS - benchmark installed to the specified directoryCopy the code

Custom configuration files

#Creating a Configuration DirectoryRoot @ DESKTOP: / usr/local/SRC/REDIS/REDIS - 6.2.3 # mkdir MYCONF#Copy the /redis-6.2.3/redis.conf redis server configuration file to MYCONFRoot @ DESKTOP: / usr/local/SRC/REDIS/REDIS - 6.2.3 # cp REDIS. Conf MYCONF /Copy the code

Modifying a Configuration File

Root @ DESKTOP: / usr/local/SRC/REDIS CD MYCONF/root/REDIS - 6.2.3 # @ DESKTOP: / usr/local/SRC/REDIS/REDIS - 6.2.3 / MYCONF# vim redis.confCopy the code

Redis does not start in the background by default. If you normally want it to start in the background, change it as follows:

daemonize no
#Modified to
daemonize yes
Copy the code

By default, Redis does not have a login password, and the official password configuration section is commented, and the corresponding password is added for security reasons:

#requirepass foobared
#Modified to
requirepass wsharkcoder
#The password is wsharkcoder

### Redis server started

``` shell
#Boot mode: redis-server < profile >Root @ DESKTOP: / usr/local/SRC/REDIS/REDIS - 6.2.3 / MYCONF# REDIS server/usr/local/SRC/REDIS/REDIS - 6.2.3 / MYCONF/REDIS.

The Redis built-in client connects to the Redis server

Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.

Close the Redis

#Redis- you can use shutdown to shutdown the cli connectionLocalhost: 6379 > shutdown not connected > root @ DESKTOP: / usr/local/SRC/REDIS/REDIS - 6.2.3 / MYCONF# ps - ef | grep - e REDIS root  17824 11798 0 18:41 pts/0 00:00:00 grep --color=auto -e redisCopy the code

The startup script

#Simple script startupRoot @ DESKTOP: / usr/local/SRC/REDIS/REDIS - 6.2.3 # touch Start_Redis. Sh # create startup scripts Root @ DESKTOP: / usr/local/SRC/REDIS/REDIS - 6.2.3 # vim Start_Redis.

Shell scripts and commands are the same. More convenient script way, learned to use in the future and then add, hey hey ~

conclusion

Here is the source code compilation of the installation, we know that the Linux platform installation software also includes the use of package management software, the way is relatively simple will not repeat the introduction! If you think my article is helpful to you, give me a thumbs up!
