Install redis under linux

Download the latest stable version from the official website

• Open the official website address

• Right-click to copy the download address as follows:
  

• Linux common commands

  • Create directory mkdir software
  • Download the compressed package wget http://download.redis.io/releases/redis-5.0.3.tar.gz
  • delete directory rm -rf redis
  • -r is to recurse downwards, no matter how many levels of directories there are, delete them together
  • -f means to delete directly without any prompt
  • Delete folder instance: rm -rf /var/log/httpd/access
  • The /var/log/httpd/access directory and all files and folders under it will be deleted
  • Delete file usage example: rm -f /var/log/httpd/access.log
  • The file /var/log/httpd/access.log will be deleted forcibly
  • Decompress the compressed package tar zxvf redis-5.0.3.tar.gz
  • Compile the file ./config

• Open linux and enter the following command:

  • mkdir software (create directory)
  • wget download address
  • Unzip the source code and enter the directory (zxvf redis-5.0.3.tar.gz )(cd redis-5.0.3 )
  • no config
  • Direct make (if it is a 32-bit machine make 32bit)

• 注:易碰到的问题,时间错误.

  • Reason: The source code is officially configured, but when the official configure, the generated file has timestamp information,
  • Make can only happen after configure,
  • If the time of your virtual machine is wrong, for example, it is 2012
  • Solution: date -s 'yyyy-mm-dd hh:mm:ss' rewrite time, then clock -w write cmos

• Optional step: make test to test compilation

  • (It may appear: need tcl >8.4, you need to enter the command yum install tcl)

• make compile

• make test test (if the above need tcl>8.4 occurs)

• Switch to root (su root)

• Then execute yum install tcl

• Try it in make test to see if the system is satisfied and if there is any error in compiling

• Install to a specified directory, such as /usr/local/redis

• Specify directory installationmake PREFIX=/usr/local/redis install

• 注: PREFIX要大写

• After make install, the following files are obtained

• redis-benchmark performance testing tool

• redis-check-aof log file detection tool (for example, log damage caused by power failure, can be detected and repaired (tool for checking aof log)

• redis-check-dump snapshot file detection tool, effect class (tool for checking rdb logs)

• redis-cli client (client for connection)

• redis-server server (redis service process)

• ll bin (view all sub-files under the current bin directory)

• Copy the configuration file (copy the redis.conf file in the source code to the current directory)

• cp /home/zcx/Software/redis-5.0.3/redis.conf ./

After copying the configuration file, start redis (you need to call the server binary file because it is a service process)

• To start the server binary file and find a way to specify this to let him use this conf file to let him start
• The startup command is as follows:
• ./bin/redis-server ./redis.conf

(Make this configuration file in the current directory as its startup condition)

• The following appears to indicate successful execution
  

• If ctr C exits this process, it will be killed (in order to observe its changes, do not close it first, there will be a way to make it run in the background later)

client connection

• Open another terminal

• cd /usr/local/redis/

• ./bin/redis-cli
  

• show success

Let redis run as a background process

• Vim edits the conf configuration file and modifies the following content;\
• daemonize yes
• just restart
• ps aux|grep redis (view redis process)
• ./redis-cli shutdown (close the default port
  )
• ps aux|grep redis (view redis process)
• ./redis-cli shutdown (close the default port)
