CentOS 7部署redis 5.0.5

Redis基於內存存儲的非關係型數據庫，存儲速度快，支持主從複製，支持字符串(string)、列表(list)、集合(set)、散列(hash)、有序集合(zset) 五種數據類型,

1、數據庫安裝

一、使用yum安裝
[root@test ~]# yum install redis

[root@test ~]# redis-server --version
Redis server v=3.2.12 sha=00000000:0 malloc=jemalloc-3.6.0 bits=64 build=7897e7d0e13773f
[root@test ~]# redis-cli --version              //能夠看出使用yum安裝的版本都比較舊，下面咱們安裝最新的5.0.5版本的redis
redis-cli 3.2.12

二、編譯安裝最新版本redis

[root@test ~]# wget http://download.redis.io/releases/redis-5.0.5.tar.gz

[root@test ~]# tar -zxvf redis-5.0.5.tar.gz

[root@test ~]# yum install gcc -y       //gcc -v查看，若是沒有須要安裝

[root@test redis-5.0.5]# make MALLOC=lib

[root@test redis-5.0.5]# cd src && make all

[root@test src]# make install

[root@test src]# ./redis-server

  `-._    `-._`-.__.-'_.-'    _.-'                                   
      `-._    `-.__.-'    _.-'                                       
          `-._        _.-'                                           
              `-.__.-'                                               

出現以上界面說明安裝成功

[root@test src]# ./redis-cli --version           //查詢是安裝的最新版本的redis
redis-cli 5.0.5
[root@test src]# ./redis-server --version
Redis server v=5.0.5 sha=00000000:0 malloc=libc bits=64 build=4db47e2324dd3c5

　　2、配置啓動數據庫

一、第一種方法就是安裝時候的./redis-server,可是這種啓動方式須要一直打開窗口，不能進行其餘操做，不太方便。

二、之後臺進程方式啓動redis

[root@test src]# vim /etc/redis-5.0.5/redis.conf   //默認安裝好的配置文件並不在這個目錄下，須要找到複製到該目錄下

daemonize no 改成 daemonize yes        //以守護進程運行            

[root@test src]# ./redis-server /etc/redis-5.0.5/redis.conf
21845:C 17 Jun 2019 15:44:14.129 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
21845:C 17 Jun 2019 15:44:14.129 # Redis version=5.0.5, bits=64, commit=00000000, modified=0, pid=21845, just started
21845:C 17 Jun 2019 15:44:14.129 # Configuration loaded

關閉redis進程
[root@test src]# ps -ef|grep redis
root     21846     1  0 15:44 ?        00:00:00 ./redis-server 127.0.0.1:6379
root     22042  6950  0 15:46 pts/1    00:00:00 grep --color=auto redis

[root@test src]# kill -9 21846

此方法啓動關閉較爲麻煩，且不能設置開機自啓動

　　3、設置系統進程啓動數據庫

先編輯配置文件，而後在把配置文件拷貝到/etc/redis下
[root@test ~]# vim /root/redis-5.0.5/redis.conf 

#bind 127.0.0.1           //將bind 127.0.0.1註釋掉，不然數據庫只有本機可以使用

daemonize yes          //將no改成yes，使數據庫可以之後臺守護進程運行

protected-mode no      //把保護模式的yes改成no,不然會阻止遠程訪問

requirepass redis         //打開註釋，設置密碼

[root@test ~]# cp /root/redis-5.0.5/redis.conf /etc/redis/

開機自啓動，將redis的啓動腳本複製一份放到/etc/init.d目錄下
[root@test redis]# vim /etc/init.d/redis

CONF="/etc/redis/redis.conf"                  //將conf的變量修改下，不然讀不到配置文件

[root@test init.d]# cp /root/redis-5.0.5/utils/redis_init_script /etc/init.d/redis

[root@test ~]# cd /etc/init.d

[root@test init.d]# chkconfig redis on

下面就能夠用systemctl管理redis
[root@test ~]# systemctl start redis

[root@test ~]# systemctl status redis
