Redis Installation instructions

Most enterprises are based on Linux Server to deploy the project , and Redis The official did not provide Windows Version of the installation package （Windows Version provided by Microsoft ）. So the next step is based on Linux System to install Redis.

Selected here Linux Version is CentOS 7.

Redis The official website address of ：https://redis.io/

1. Stand alone installation Redis

1.1. install Redis rely on

Redis Is based on C language-written , So first you need to install Redis The required gcc rely on ：

yum install -y gcc tcl

1.2. Upload the installation package and unzip it

And then Redis Upload the installation package to any directory of the virtual machine ：

for example , I put it /usr/local/src Catalog ：
If the directory cannot upload files , You can modify permissions ：

chmod a+w /usr/local/src/

decompression ：

tar -xzf redis-6.2.6.tar.gz

After decompressing ：

Get into redis Catalog ：

cd redis-6.2.6

Run the compile command ：

make && make install

If there is no error , The installation should be successful .

The default installation path is /usr/local/bin Under the table of contents ：

The directory has been configured to the environment variable by default , Therefore, you can run these commands in any directory . among ：

• redis-cli： yes redis The command line client provided
• redis-server： yes redis Server startup script
• redis-sentinel： yes redis Sentinel startup script

1.3. start-up

redis There are many ways to start , for example ：

• The default startup
• Specify the configuration to start
• Boot from boot

1.3.1. The default startup

After installation , Enter... In any directory redis-server Command to start Redis：

redis-server

Pictured ：

This startup belongs to The front desk starts , Will block the entire session window , Close the window or press CTRL + C be Redis stop it . It is not recommended to use .

1.3.2. Specify the configuration to start

If you want to make Redis With backstage Mode start , You have to modify Redis The configuration file , Just before we unzipped redis Under the installation package （/usr/local/src/redis-6.2.6）, Name is redis.conf：

Let's back up this configuration file first ：

cp redis.conf redis.conf.bck

And then modify redis.conf Some configurations in the file ：

vi redis.conf
 After entering , Input  /bind  Rapid positioning bind The location of 
 Press  i  key   Enter edit mode 
 After editing , Press ESC Post key , Input again  ：wq  Save and exit  

#  Listening address , The default is 127.0.0.1, Will result in local access only . It is amended as follows 0.0.0.0 It can be in any IP visit , The production environment should not be set to 0.0.0.0
bind 0.0.0.0
#  Daemon , It is amended as follows yes After, it can run in the background 
daemonize yes 
#  password , Access after setting Redis You must enter a password 
requirepass 123321

Redis Other common configurations ：

#  Listening port 
port 6379
#  working directory , The default is the current directory , Which is running redis-server When the command , journal 、 Files such as persistence will be saved in this directory 
dir .
#  Number of databases , Set to 1, Stands for using only 1 Databases , The default is 16 Databases , Number 0~15
databases 1
#  Set up redis Maximum memory available 
maxmemory 512mb
#  Log files , The default is empty. , Do not log , You can specify the log file name 
logfile "redis.log"

start-up Redis：

#  Get into redis The installation directory  
cd /usr/local/src/redis-6.2.6
#  start-up 
redis-server redis.conf
#  see Redis process 
ps -ef | grep redis
# kill -9  process id, Kill process 

Out of Service ：

#  utilize redis-cli To execute  shutdown  command , Just stop  Redis  service ,
#  Because the password was configured before , So it needs to pass  -u  To specify the password 
redis-cli -u 123321 shutdown

1.3.3. Boot from boot

We can also realize self startup through configuration .

First , Create a new system service file ：

vi /etc/systemd/system/redis.service

The contents are as follows ：

[Unit]
Description=redis-server
After=network.target

[Service]
Type=forking
ExecStart=/usr/local/bin/redis-server /usr/local/src/redis-6.2.6/redis.conf
PrivateTmp=true

[Install]
WantedBy=multi-user.target

Then reload the system services ：

systemctl daemon-reload

Now? , We can use the following set of commands to operate redis 了 ：

#  start-up 
systemctl start redis
#  stop it 
systemctl stop redis
#  restart 
systemctl restart redis
#  Check the status 
systemctl status redis

Execute the following command , It can make redis Boot from boot ：

systemctl enable redis

2.Redis client

installation is complete Redis, We can operate Redis, To achieve data CRUD 了 . It needs to use Redis client , Include ：

• Command line client
• Graphical desktop client
• Programming client

2.1.Redis Command line client

Redis After the installation is completed, the command-line client comes with it ：redis-cli, Use as follows ：

redis-cli [options] [commonds]

One of the common ones is options Yes ：

• -h 127.0.0.1： Specify the... To connect to redis Node IP Address , The default is 127.0.0.1
• -p 6379： Specify the... To connect to redis Port of node , The default is 6379
• -a 123321： Appoint redis Access code for

Among them commonds Namely Redis Operation command of , for example ：

• redis-cli -a Input password
• ping： And redis The server does a heartbeat test , The server will normally return pong
  

Don't specify commond when , Will enter redis-cli Interactive console ：

• First use redis-cli Access control
• Enter after entering auth + password
  

2.2. Graphical desktop client

GitHub The great God of wrote Redis Graphical desktop client , Address ：https://github.com/uglide/RedisDesktopManager

But the warehouse provides RedisDesktopManager Source code , Not provided windows Installation package .

The installation package can be found in the following warehouse ：https://github.com/lework/RedisDesktopManager-Windows/releases

2.2.1. install

After decompression , Run the installer to install ：

Here slightly .

After installation , Found in the installation directory rdm.exe file ：

Double click to run ：

2.2.2. Establishing a connection

Click on the top left Connect to Redis The server Button ：

Fill in the pop-up window Redis Service information ：

Click OK , This link will appear in the left menu ：

Click to establish a connection ：

Redis The default is 16 A warehouse , Number from 0 to 15. The number of warehouses can be set through the configuration file , But no more than 16, And you can't customize the warehouse name .

If it is based on redis-cli Connect Redis service , Can pass select Command to select the database ：

#  choice  0 Signal library
