Redis installation under Linux

One 、 install gcc Environmental Science

     because redis By C language-written , Its operation requires C Environmental Science , So we need to install gcc. The installation command is as follows ：

    [[email protected]_SW_5748F_1 local]# yum install gcc-c++

    Check whether the installation is successful

   [[email protected]_SW_5748F_1 local]# gcc -v

Two 、 download Redis Installation package

    use wget Directly in linux Download in the environment ,                     // wget Is a free tool to download files from the Internet automatically

   [[email protected]_SW_5748F_1 lhl]# wget http://download.redis.io/releases/redis-4.0.1.tar.gz
   [[email protected]_SW_5748F_1 lhl]# pwd
     /lhl
   [[email protected]_SW_5748F_1 lhl]# ls
   redis-4.0.1.tar.gz

3、 ... and 、 Unpack the installation
   [[email protected]_SW_5748F_1 lhl]# tar -zvxf redis-4.0.1.tar.gz     // unpack

   [[email protected]_SW_5748F_1 lhl]# ls
   redis-4.0.1  redis-4.0.1.tar.gz
   [[email protected]_SW_5748F_1 lhl]# cd redis-4.0.1
   [[email protected]_SW_5748F_1 redis-4.0.1]# ls
   00-RELEASENOTES  BUGS  CONTRIBUTING  COPYING  deps  INSTALL  Makefile  MANIFESTO  README.md  redis.conf                 runtest   runtest-cluster  runtest-sentinel  sentinel.conf  src       tests  utils
   [[email protected]_SW_5748F_1 redis-4.0.1]# make              // Compile the extracted file

   [[email protected]_SW_5748F_1 redis-4.0.1]# make install         // Yes Redis Installation
 

  The installation was successful as follows

[[email protected]_SW_5748F_1 redis-4.0.1]# make install
cd src && make install
make[1]:  Entry directory “/lhl/redis-4.0.1/src”
    CC Makefile.dep

Hint: It's a good idea to run 'make test' ;)

    INSTALL install
    INSTALL install
    INSTALL install

make[1]:  Leave the directory “/lhl/redis-4.0.1/src”

Four 、 start-up Redis

  [[email protected]_SW_5748F_1 redis-4.0.1]# cd src
  [[email protected]_SW_5748F_1 src]# ls
  redis-cli  redis-server  // Will see redis Some configuration startup files , There are only two copies here

  [[email protected]_SW_5748F_1 src]# redis-server
 

[[email protected]_SW_5748F_1 src]# redis-server

11981:M 30 Mar 22:08:43.227 # WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.
11981:M 30 Mar 22:08:43.227 # Server initialized

5、 ... and 、 Connect Redis

  Because it doesn't run in the background , So you need to re create a window connection

 [[email protected]_SW_5748F_1 src]# redis-cli -p 6379

[[email protected]_SW_5748F_1 src]# redis-cli -p 6379
127.0.0.1:6379> ping
PONG
127.0.0.1:6379> set k1 v1
OK
127.0.0.1:6379> get k1
"v1"
127.0.0.1:6379> shutdown  // sign out 
not connected> exit
[[email protected]_SW_5748F_1 src]# 

6、 ... and 、 To configure Redis（ Give Way Redis Running in the background , It's actually a daemon thread ）

 [[email protected]_SW_5748F_1 redis-4.0.1]# mkdir /usr/config     // establish config Folder
 [[email protected]_SW_5748F_1 redis-4.0.1]# cp redis.conf /usr/config     // Copy redis.conf To /usr/config Folder
 [[email protected]_SW_5748F_1 redis-4.0.1]# cd /usr/config

  modify redis.conf file

 [[email protected]_SW_5748F_1 config]# vim redis.conf            //daemonize no Change to yes
 

7、 ... and 、 Start again redis

  [[email protected]_SW_5748F_1 src]# redis-server /usr/config/redis.conf    // start-up redis And specify the configuration file       go back to redis-server directory

  [[email protected]_SW_5748F_1 src]# ps -ef|grep redis             // see redis Whether the process exists

[[email protected]_SW_5748F_1 src]# redis-server /usr/config/redis.conf
12367:C 30 Mar 22:41:27.556 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
12367:C 30 Mar 22:41:27.556 # Redis version=4.0.1, bits=64, commit=00000000, modified=0, pid=12367, just started
12367:C 30 Mar 22:41:27.556 # Configuration loaded
[[email protected]_SW_5748F_1 src]# ps -ef|grep redis
