Centos-7.4_安裝_Redis_4.0.8

1、安裝redis

第一步:下載redis安裝包

[root@Redis ~]# mkdir /usr/local/redis/                      --建立目錄redis

[root@Redis redis]# cd /usr/local/redis/                        --進入當前目錄vim

[root@Redis ~]# wget http://download.redis.io/releases/redis-4.0.8.tar.gz       --下載軟件包

第二步:解壓壓縮包

[root@Redis redis]# tar -zxvf redis-4.0.8.tar.gzidea

第三步:yum安裝gcc依賴

[root@Redis redis]# yum -y install gcc-*spa

第四步:跳轉到redis解壓目錄下

[root@Redis redis]# cd redis-4.0.8/.net

第五步:編譯安裝

[root@Redis redis]# make MALLOC=libcrest

將/usr/local/redis-4.0.8/src目錄下的文件加到/usr/local/bin目錄server

cd src && make install

[root@Redis redis-4.0.8]# cd src && make install
CC Makefile.dep

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

INSTALL install
INSTALL install
INSTALL install
INSTALL install
INSTALL install

2、啓動redis的三種方式

先切換到redis src目錄下

[root@Redis redis-4.0.8]# cd src/

一、直接啓動redis

[root@Redis src]# ./redis-server
35611:C 30 Dec 12:16:11.035 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
35611:C 30 Dec 12:16:11.036 # Redis version=4.0.8, bits=64, commit=00000000, modified=0, pid=35611, just started
35611:C 30 Dec 12:16:11.036 # Warning: no config file specified, using the default config. In order to specify a config file use ./redis-server /path/to/redis.conf
35611:M 30 Dec 12:16:11.036 * Increased maximum number of open files to 10032 (it was originally set to 1024).

35611:M 30 Dec 12:16:11.037 # WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.
35611:M 30 Dec 12:16:11.037 # Server initialized
35611:M 30 Dec 12:16:11.037 # 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.
35611:M 30 Dec 12:16:11.037 # 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.
35611:M 30 Dec 12:16:11.037 * 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。

二、之後臺進程方式啓動redis

第一步:修改redis.conf文件

[root@Redis src]# vim /usr/local/redis/redis-4.0.8/redis.conf 

daemonize no

修改成

daemonize yes

第二步:指定redis.conf文件啓動

[root@Redis src]# ./redis-server /usr/local/redis/redis-4.0.8/redis.conf
45390:C 30 Dec 12:42:32.886 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
45390:C 30 Dec 12:42:32.886 # Redis version=4.0.8, bits=64, commit=00000000, modified=0, pid=45390, just started
45390:C 30 Dec 12:42:32.886 # Configuration loaded

第三步:關閉redis進程

首先使用ps -aux | grep redis查看redis進程

[root@Redis src]# ps -aux | grep redis
root 45391 0.0 0.0 141816 2004 ? Rsl 12:42 0:00 ./redis-server 127.0.0.1:6379

使用kill命令殺死進程

[root@Redis src]# kill -9 45391

三、設置redis開機自啓動

一、在/etc目錄下新建redis目錄

mkdir redis

[root@Redis src]# mkdir /etc/redis

二、將/usr/local/redis/redis-4.0.8/redis.conf 文件複製一份到/etc/redis目錄下,並命名爲6379.conf

[root@Redis src]# cp /usr/local/redis/redis-4.0.8/redis.conf /etc/redis/6379.com 

三、將redis的啓動腳本複製一份放到/etc/init.d目錄下

[root@Redis src]# cp /usr/local/redis/redis-4.0.8/utils/redis_init_script /etc/init.d/redisd

四、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@Redis init.d]# chkconfig redisd on
服務 redisd 不支持 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

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@Redis 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

若是出現以下問題:

[root@Redis ~]# service redisd start 
Please use start or stop as first argument

可用安裝文件啓動     redis-server /etc/redis/6379.conf

[root@Redis ~]# redis-server /etc/redis/6379.conf
9562:C 30 Dec 13:44:57.160 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
9562:C 30 Dec 13:44:57.160 # Redis version=4.0.8, bits=64, commit=00000000, modified=0, pid=9562, just started
9562:C 30 Dec 13:44:57.160 # Configuration loaded
