Linux下Redis的安装

一、安装gcc环境

    由于redis是由C语言编写的，它的运行需要C环境，因此我们需要先安装gcc。安装命令如下：

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

   查看是否安装成功

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

二、下载Redis安装包

   用wget直接在linux环境下下载，                     // wget 是一个从网络上自动下载文件的自由工具

   [[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

三、解压安装
   [[email protected]_SW_5748F_1 lhl]# tar -zvxf redis-4.0.1.tar.gz     //进行解压

   [[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              //对解压后的文件进行编译

   [[email protected]_SW_5748F_1 redis-4.0.1]# make install         //对Redis进行安装
 

  安装成功如下

[[email protected]_SW_5748F_1 redis-4.0.1]# make install
cd src && make install
make[1]: 进入目录“/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
    INSTALL install
    INSTALL install
make[1]: 离开目录“/lhl/redis-4.0.1/src”

四、启动Redis

  [[email protected]_SW_5748F_1 redis-4.0.1]# cd src
  [[email protected]_SW_5748F_1 src]# ls
  redis-cli  redis-server  //会看到redis一些配置启动文件，这里只复制了两个

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

[[email protected]_SW_5748F_1 src]# redis-server
11981:C 30 Mar 22:08:43.224 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

           _.-``__ ''-._

              `-.__.-'                                               

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

五、连接Redis

  因为不是在后台运行，所以需要重新创建一个窗口连接

 [[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  //退出
not connected> exit
[[email protected]_SW_5748F_1 src]# 

六、配置Redis（让Redis在后台运行，其实是守护线程）

 [[email protected]_SW_5748F_1 redis-4.0.1]# mkdir /usr/config     //创建config文件夹
 [[email protected]_SW_5748F_1 redis-4.0.1]# cp redis.conf /usr/config     //复制redis.conf到 /usr/config文件夹
 [[email protected]_SW_5748F_1 redis-4.0.1]# cd /usr/config

 修改redis.conf文件

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

七、再次启动redis

  [[email protected]_SW_5748F_1 src]# redis-server /usr/config/redis.conf    //启动redis并且指定配置文件     回到redis-server所在的目录

  [[email protected]_SW_5748F_1 src]# ps -ef|grep redis             //查看redis进程是否存在

[[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
root      12368      1  0 22:41 ?        00:00:00 redis-server 127.0.0.1:6379
root      12373   7913  0 22:41 pts/0    00:00:00 grep --color=auto redis
[[email protected]_SW_5748F_1 src]# 

成功完成，有问题可以问我
