Redis installation test

Use the source code to install and compile :  

Install the source code compilation support library ：yum install gcc gcc-c++

Download package ：wget https://download.redis.io/releases/redis-6.2.3.tar.gz

Unzip the package ：tar xzf redis-6.2.3.tar.gz

Get into redis Catalog ：cd redis-6.2.3

Compilation and installation ：make

( This process takes a long time ,)

After completion : Get into redis Execute... In directory make test command :

 

Pictured : Initial configuration , Two errors in the figure will appear ,, The solution is as follows :

Need to install TCL:

TCL8.6 install

wget Download Tcl from SourceForge.net

tar xzvf tcl8.6.1-src.tar.gz  -C /usr/local/

cd  /usr/local/tcl8.6.1/unix/

./configure

make

make install

The installation is basically finished here :

Then start redis, 

 

There are two possible warnings ;

 

Solution :

The solution to the first problem :

 

The solution to the second problem : modify /etc/sysctl.conf The content of the file is shown in the figure :

 

Then you need to restart the service , This time you need to specify a file to start : Pictured

 

The front-end start Redis after , The terminal will enter Redis Console , There's no way to go on Linux command , That is, the terminal window is ” Abandoned ”, Input only Redis My orders . Need to restart a terminal window .

In the new window : Enter the following command , You can write data to it .

 

Here we need to pay attention to : The same key value , The later entry will overwrite the previous content .

Front end initiated shutdown command ：

closed ：Ctrl+c

Normally shut down ：./redis-cli shutdown

• Forced shutdown is only required in Redis The console can execute directly （redis Some data may be lost ）.
• Normal closing requires opening another terminal window （redis No loss of data , Recommended ）.

Start and stop of the backend ;

1. To start the backend, you need to modify the configuration file : modify redis.conf file , take daemonize To change the value of yes After saving .
2. 
3. Backend start command : src/redis-server redis.conf
4.  

Back end shutdown command ;

closed ：kill -9 process id

Normally shut down ：src/redis-cli shutdown

                   

Redis client

1、redis It comes with its own client

Introduced earlier redis Installation directory src The structure of the directory , It has been marked redis The client of , It is redis-cli. This client has two common functions ：

• Used to shut down normally redis service .
• Let the terminal enter redis Console （ Background operation redis In the scenario of ）.

start-up :

src/redis-cli -h 127.0.0.1 -p 6379

• -h： Specify the access to redis Server's ip Address
• -p： Specify the access to redis Server's port port
• If used ip The address and port are the default , Then the above command can be written as follows ：src/redis-cli

close : quit

Graphical interface client :

There is one redis GUI client software , be known as redis-destop-manager. Support Windows、Mac OS X、Linux, Please choose to download according to your computer system , Here we use windows For example , In brief, the use of this software , Easy to install , All the way to the next step , Open the application after installation .

1、 modify redis Under the folder redis.conf file , stay bind 127.0.0.1 Add before the line # Comment out this line , Enable remote connection （ By default, only local connections can be used ）.

 

 

And then use kill command , Kill those opened before redis service , Then restart the service in the background , Here, you should pay attention to starting according to the configuration file : command :

stay redis Execute under directory  src/redis-server redis.conf  use redis.conf Reset of set parameters redis-server service .

4、 Command line execution src/redis-cli  Get into redis Command line , perform config set requirepass 123456  Set password for graphical interface login connection

5、 stay RedisDesktopManager The client enters the user name 、 password 、 Server address 、 Port to server , Click test connection .

 

After success , You can see that redis Next 16 Databases , From here, you can view redis The operation test has been carried out .
