1、安裝redislinux

第一步：下載redis安裝包redis

wget http://download.redis.io/releases/redis-4.0.6.tar.gzvim

[root@localhost ~]# wget http://download.redis.io/releases/redis-4.0.6.tar.gzcentos

第二步：解壓壓縮包

tar -zxvf redis-4.0.6.tar.gz

[root@localhost home]# tar -zxvf redis-4.0.6.tar.gz

第三步：yum安裝gcc依賴

yum install gcc

[root@localhost home]# yum install gcc

遇到選擇,輸入y便可

第四步：跳轉到redis解壓目錄下

cd redis-4.0.6

[root@localhost home]# cd redis-4.0.6

第五步：編譯安裝

make MALLOC=libc　　

[root@localhost redis-4.0.6]# make MALLOC=libc

將/usr/local/redis-4.0.6/src目錄下的文件加到/usr/local/bin目錄 cp –rf 就行

cd src && make install

[root@localhost redis-4.0.6]# cd src && make install

CC Makefile.dep

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

INSTALL install

2、啓動redis的三種方式

先切換到redis src目錄下

[root@localhost redis-4.0.6]# cd src

1、直接啓動redis

./redis-server

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

18685:C 13 Dec 12:56:12.507 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

18685:C 13 Dec 12:56:12.507 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=18685, just started

18685:C 13 Dec 12:56:12.507 # Warning: no config file specified, using the default config. In order to specify a config file use ./redis-server /path/to/redis.conf

18685:M 13 Dec 12:56:12.508 # Server initialized

18685:M 13 Dec 12:56:12.508 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.

18685:M 13 Dec 12:56:12.508 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.

18685:M 13 Dec 12:56:12.508 * Ready to accept connections　　

如上圖：redis啓動成功，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。

按 ctrl + c能夠關閉窗口。

2、之後臺進程方式啓動redis

第一步：修改redis.conf文件

將

daemonize no

修改成

daemonize yes

第二步：指定redis.conf文件啓動

1	./redis-server /usr/local/redis-4.0.6/redis.conf

[root@localhost src]# ./redis-server /usr/local/redis-4.0.6/redis.conf

18713:C 13 Dec 13:07:41.109 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

18713:C 13 Dec 13:07:41.109 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=18713, just started

18713:C 13 Dec 13:07:41.109 # Configuration loaded

第三步：關閉redis進程

首先使用ps -aux | grep redis查看redis進程

[root@localhost src]# ps -aux | grep redis

root 18714 0.0 0.1 141752 2008 ? Ssl 13:07 0:00 ./redis-server 127.0.0.1:6379

root 18719 0.0 0.0 112644 968 pts/0 R+ 13:09 0:00 grep --color=auto redis

使用kill命令殺死進程

[root@localhost src]# kill 18714

3、設置redis開機自啓動

mkdir redis

[root@localhost etc]# mkdir redis

2、將/usr/local/redis-4.0.6/redis.conf 文件複製一份到/etc/redis目錄下，並命名爲6379.conf　　

[root@localhost redis]# cp /usr/local/redis-4.0.6/redis.conf /etc/redis/6379.conf

3、將redis的啓動腳本複製一份放到/etc/init.d目錄下

[root@localhost init.d]# cp /usr/local/redis-4.0.6/utils/redis_init_script /etc/init.d/redisd

4、設置redis開機自啓動

先切換到/etc/init.d目錄下

而後執行自啓命令

[root@localhost init.d]# chkconfig redisd on

service redisd does not support chkconfig　

看結果是redisd不支持chkconfig

解決方法：

使用vim編輯redisd文件，在第一行加入以下兩行註釋，保存退出

# chkconfig: 2345 90 10

# description: Redis is a persistent key-value database

註釋的意思是，redis服務必須在運行級2，3，4，5下被啓動或關閉，啓動的優先級是90，關閉的優先級是10。

再次執行開機自啓命令，成功

[root@localhost init.d]# chkconfig redisd on

如今能夠直接已服務的形式啓動和關閉redis了

啓動：

service redisd start　

[root@localhost ~]# service redisd start

Starting Redis server...

2288:C 13 Dec 13:51:38.087 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

2288:C 13 Dec 13:51:38.087 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=2288, just started

2288:C 13 Dec 13:51:38.087 # Configuration loaded

關閉：

方法1：service redisd stop

[root@localhost ~]# service redisd stop

Stopping ...

Redis stopped

方法2：redis-cli SHUTDOWN

3、linux服務器端能夠鏈接而遠程沒法鏈接的緣由

[root@localhost src]# vim ../redis.conf

把protected-mode yes改成protected-mode no（在沒有密碼的狀況下，關閉保護模式）

註釋掉bind 127.0.0.1 （取消綁定本地地址）

把daemonize no改成daemonize yes （是否爲進程守護，關閉ssh窗口後便是否在後臺繼續運行）

在redis-conf註釋掉bind 127.0.0.1 （取消綁定本地地址）

若還不能訪問則開啓制定端口號或者關閉防火牆，在這採用關閉防火牆，因爲是centos7，防火牆進行了升級

systemctl stop firewalld.service #中止firewall

systemctl disable firewalld.service #禁止firewall開機啓動

若是出現以下問題：

[root@localhost ~]# service redisd start

/var/run/redis_6379.pid exists, process is already running or crashed

刪除redis_6379.pid便可
