Foreword

It is more troublesome to start Redis every time you want to use Redis. We can directly set the startup to start automatically, so that we do not need to manually operate it every time.This article teaches you how to implement self-starting at boot by configuration.

I. What is Redis?

Redis is completely open source, complies with the BSD protocol, and is a high-performance key-value database.

Redis and other key-value caching products have the following three characteristics:

1. Redis supports data persistence, which can save data in memory on disk, and can be loaded again for use when restarting.

2. Redis not only supports simple key-value type data, but also provides storage of data structures such as list, set, zset, and hash.

3.Redis supports data backup, that is, data backup in master-slave mode.

Second, use steps

1. Create a new system service file

First enter the command: vi /etc/systemd/system/redis.service

After entering vim, paste the code below, and pay attention to check whether the address is the same.

After ExecStart is the installation location of your redis-server and the directory of the redis configuration file

[Unit]Description=redis-serverAfter=network.target[Service]Type=forkingExecStart=/usr/local/redis/bin/redis-server /usr/local/redis/redis-6.2.6/redis.confPrivateTmp=true[Install]WantedBy=multi-user.target

2. Reload system services

The command is as follows:

systemctl daemon-reload

3. Start and view Redis

The command is as follows:

#Start Redissystemctl start redis#View Redis statussystemctl status redis

You can see that Redis is already running (running)

4. Stop Redis

The command is as follows:

systemctl stop redis

You can see that Redis is dead

5. Self-start at boot

After entering the command, Redis realizes the function of self-starting at boot. The command is as follows:

systemctl enable redis
