跟大家讲解下有关如何在centos系统下安装redis数据库，相信小伙伴们对这个话题应该也很关注吧，现在就为小伙伴们说说如何在centos系统下安装redis数据库，小编也收集到了有关如何在centos系统下安装redis数据库的相关资料，希望大家看到了会喜欢。

具体安装步骤如下：

一、安装redis

第一步：下载redis安装包

[[emailprotected] local]# wget http://download.redis.io/releas/redis-4.0.6.tar.gz--2017-12-13 12:35:12-- http://download.redis.io/releas/redis-4.0.6.tar.gzResolving download.redis.io (download.redis.io)... 109.74.203.151Connecting to download.redis.io (download.redis.io)|109.74.203.151|:80... connected.HTTP request nt, awaiting respon... 200 OKLength: 1723533 (1.6M) [application/x-gzip]Saving to: ‘redis-4.0.6.tar.gz’100%[==========================================================================================================>] 1,723,53动态搞笑图片笑死人3 60卧轨自杀8KB/s in 2.8s 2017-12-13 12:35:15 (608 KB/s) - ‘redis-4.0.6.tar.gz’ saved [1723533/1723533]

第二步：解压压缩包

tar -zxvf redis-4.0.6.tar.gz[[emailprotected] local]# tar -zxvf redis-4.0.6.tar.gz

第三步：yum安装gcc依赖

yum install gcc[[emailprotected] local]# yum install gcc

遇到选择,输入y即可

第四步：跳转到redis解压目录下

cd redis-4.0.6[[emailprotected] local]# cd redis-4.0.6

第五步：编译安装

make MALLOC=libc　　[[emailprotected] redis-4.0.6]# make MALLOC=libc

将/usr/local/redis-4.0.6/src目录下的文件加到/usr/local/bin目录

cd src && make install

[[emailprotected] redis-4.0.6]# cd src && make install CC Makefile.depHint: It's a good idea to run 'make test' ;) INSTALL install INSTALL install INSTALL install INSTALL install INSTALL install

二、启动redis的三种方式

先切换到redis src目录下

[[emailprotected] redis-4.0.6]# cd src

1、直接启动redis

./redis-rver

[[emailprotected] src]# ./redis-rver18685:C 13 Dec 12:56:12.507 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo18685:C 13 Dec 12:56:12.507 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=18685, just started18685:C 13 Dec 12:56:12.507 # Warning: no config file specified, using the default config. In order to specify a config file u ./redis-rver /path/to/redis.conf _._ _.-``__ ''-._ _.-`` `. `_. ''-._ Redis 4.0.6 (00000000/0) 64 bit .-`` .-```. ```\/ _.,_ ''-._ ( ' , .-` | `, ) Running in standalone mode |`-._`-...-` __...-.``-._|'` _.-'| Port: 6379 | `-._ `._ / _.-' | PID: 18685 `-._ `-._ `-./ _.-' _.-' |`-._`-._ `-.__.-' _.-'_.-'| | `-._`-._ _.-'_.-' | http://redis.io `-._ `-._`-.__.-'_.-' _.-' |`-._`-._ `-.__.-' _.-'_.-'| | `-._`-._ _.-'_.-' | `-._ `-._`-.__.-'_.-' _.-' `-._ `-.__.-' _.-' `-._ _.-' `-.__.-' 18685:M 13 Dec 12:56:12.508 # WARNING: The TCP backlog tting of 511 cannot be enforced becau /proc/sys/net/core/somaxconn is t to the lower value of 128.18685:M 13 Dec 12:56:12.508 # Server initialized18685:M 13 Dec 12:56:12.508 # WARNING overcommit_memory is t 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 tting after a reboot. Redis must be restarted after THP is disabled.18685:M 13 Dec 12:56:12.508 * Ready to accept connections

如上图：redis启谦虚动成功但是这种启动方式需要一直打开窗口不能进行其他操作不太方便。

按 ctrl + c可以关闭窗口。

2、以后台进程方式启动redis

第一步：修改redis.conf文件

将

daemonize no

修改为

daemonize yes

第二步：指定redis.conf文件启动

./redis-rver /usr/local/redis-4.0.6/redis.conf [[emailprotected] src]# ./redis-rver /usr/local/redis-4.0.6/redis.conf 18713:C 13 Dec 13:07:41.109 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo18713:C 13 Dec 13:07:41.109 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=18713, just started18713:C 13 Dec 13:07:41.109 # Configuration loaded

第三步：关闭redis进程

首先使用ps -aux | grep redis查看redis进程

[[emailprotected] src]# ps -aux | grep redisroot 18714 0.0 0.1 141752 2008 ? Ssl 13:07 0:00 ./redis-rver 127.0.0.1:6379root 18719 0.0 0.0 112644 968 pts/0 R+ 13:09 0:00 grep --color=auto redis

使用kill命令杀死进程

[[emailprotected] src]# kill 18714

3、设置redis开机自启动

1、在/etc目录下新建redis目录

mkdir redis[[emailprotected] etc]# mkdir redis

2、将/usr/local/redis-4.0.6/redis.conf 文件复制一份到/etc/redis目录下并命名为6379.conf　　

[[emailprotected] redis]# cp /usr/local/redis-4.0.6/redis.conf /etc/redis情侣称呼/6379.conf

3、将redis的启动脚本复制一份放到/etc/init.d目录下

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

4、设置redis开机自启动

先切换到/etc/init.d目录下

然后执行自启命令

[[emailprotected] init.d]# chkconfig redisd onrvice redisd does not support chkconfig　

看结果是redisd不支持chkconfig

解决方法：

使用vim编辑redisd文件在第一行加入如下两行注释保存退出

# chkconfig: 2345 90 10# description: Redis is a persistent key-value databa

注释的意思是redis服务必须在运行级2345下被启动或关闭启动的优先级是90关闭的优先级是10

再次执行开机自启命令成功

[[emailprotected] init.d]# chkconfig redisd on

现在可以直接已服务的形式启动和关闭redis了

启动：

rvice redisd start　[[emailprotected] ~]# rvice redisd startStarting Redis rver...2288:C 13 Dec 13:51:38.087 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo2288:C 13 Dec 13:51:38.087 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=2288, just started2288:C 13 Dec 13:51:38.087 # Configuration loaded

关闭：

方法1：rvice redisd stop

[[emailprotected] ~]# rvice redisd stopStopping ...Redis stopped

方法2：redis-cli SHUTDOWN

如果出现如下问题：

[[ema天际歌词ilprotected] ~]# rvice redisd start/var/run/redis_6379.pid exists, process is already running or crashed
