Linux install redis database

1. The first step to download the redis database

cd /usr/local

mkdir Redis

cd /usr/local/Redis

wget https://download.redis.io/releases/redis-6.2.7.tar.gz

2 Unzip

tar -zxvf redis-6.2.7.tar.gz

3 Check the installation environment, C language support is required

gcc --version

My linux already comes with c language environment, if not, please install it by yourself, the command is

yum install gcc

If there is no yum command, please install the yum source first. If there is no yum command, an error will be reported

Error: Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again

Install yum command reference

(1) Check the gcc environment gcc --version

(2) If there is no problem with the gcc environment, execute the command make distclean

5 install redis

make install

The installed files are under /usr/local/bin

cd /usr/local/bin

ls

6 start redis

(1) Redis is started in the foreground, and it cannot run after the window is closed (not recommended)

redis-server

(2) Modify the configuration file, note that the configuration file is in the decompression directory of the second step, here is /usr/local/Redis/redis-6.2.7 (recommended)

cd /usr/local/Redis/redis-6.2.7

vi redis.conf

Press q twice to query, the query content is /daemonize

    Press insert to edit

Change daemonize no to daemonize yes

    Version problem, some versions do not havedaemonize,Add manually if not

  Start command:redis-server The full path of the redis.conf file, such as

redis-server /usr/local/Redis/redis-6.2.7/redis.conf

If no error is reported, it means that redis is running successfully. The command to check whether redis is running successfully is:

ps -ef | grep redis
