centos 7 下安装 redis

一、安装redis服务

第一步：下载redis安装包

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

[root@chenzhengduan local]# wget http://download.redis.io/releases/redis-4.0.6.tar.gz

---- ::--  http://download.redis.io/releases/redis-4.0.6.tar.gz

-- :: ( KB/s) - ‘redis-4.0..tar.gz’ saved [/]

第二步：解压压缩包

命令：tar -zxvf redis-4.0.6.tar.gz

[root@chenzhengduan local]# tar -zxvf redis-4.0..tar.gz

第三步：yum安装gcc依赖（如已安装可跳过此步骤）

命令：yum install gcc

[root@chenzhengduan  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

命令：cd redis-4.0.6

[root@chenzhengduan local]# cd redis-4.0.

第五步：编译安装

命令：make MALLOC=libc

[root@chenzhengduan redis-4.0.]# make MALLOC=libc

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

redis 目录下执行命令 cd src && make install

[root@chenzhengduan redis-4.0.]# 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

二、启动redis的三种方式

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

:C  Dec ::12.507 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

:C  Dec ::12.507 # Redis version=4.0., bits=, commit=, modified=, pid=, just started

:C  Dec ::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

                _._

           _.-``__ ''-._

      _.-``    `.  `_.  ''-._           Redis 4.0. (/)  bit

  .-`` .-```.  ```\/    _.,_ ''-._

 (    '      ,       .-`  | `,    )     Running in standalone mode

 |`-._`-...-` __...-.``-._|'` _.-'|     Port:

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

 |    `-._`-._        _.-'_.-'    |           http://redis.io

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

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

 |    `-._`-._        _.-'_.-'    |

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

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

          `-._        _.-'

              `-.__.-'                                               

:M  Dec ::12.508 # WARNING: The TCP backlog setting of  cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of .

:M  Dec ::12.508 # Server initialized

:M  Dec ::12.508 # WARNING overcommit_memory is set to ! 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.

:M  Dec ::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.

:M  Dec ::12.508 * Ready to accept connections

如上图：redis启动成功，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 redis 目录下命令：vim redis.conf

将 daemonize no 改成 daemonize yes

第二步：指定redis.conf文件启动

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

[root@chenzhengduan 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：关闭redis进程

首先使用ps -aux | grep redis查看redis进程

[root@chenzhengduan 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命令杀死进程

[root@chenzhengduan src]# kill 18714

3、设置redis开机自启动

mkdir redis

[root@chenzhengduan 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　　

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

3、将redis的启动脚本复制一份放到/etc/init.d目录下

[root@chenzhengduan 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

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

service 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 database

注释的意思是，redis服务必须在运行级2，3，4，5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

[root@chenzhengduan 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：

service redisd start　

[root@chenzhengduan /]# 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

关闭：

方法1：service redisd stop

[root@chenzhengduan /]# service redisd stop

Stopping ...

Redis stopped

再次启动完成~

如果遇到使用RedisDesktopManager客户端无法连接Redis服务器的问题
