root@zhao:/apps# tar xf redis-5.0.6.tar.gz 			 #解压
root@zhao:/apps# cd redis-5.0.6/					#进入目录

编译安装

需要依赖（gcc gcc-c++ make)

编译安装并指定安装位置，如果报错使用#make MALLOC=libc PREFIX=/apps/redis install

make PREFIX=/apps/redis install && cd src && make install

root@zhao:/apps/redis-5.0.6# make MALLOC=libc PREFIX=/apps/redis install
cd src && make install



make[1]: Entering directory '/apps/redis-5.0.6/src'
......
Hint: It's a good idea to run 'make test' ;)

    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
make[1]: Leaving directory '/apps/redis-5.0.6/src'

安装完后进入安装位置的目录中。

创建配置文件、日志等目录

mkdir /apps/redis/{etc,logs,run,data}

root@zhao:/apps/redis# mkdir /apps/redis/{etc,logs,run,data}
root@zhao:/apps/redis# ll
total 28
drwxr-xr-x 7 root root 4096 Apr  3 18:07 ./
drwxr-xr-x 4 1001  121 4096 Apr  3 18:03 ../
drwxr-xr-x 2 root root 4096 Apr  3 18:03 bin/
drwxr-xr-x 2 root root 4096 Apr  3 18:07 data/
drwxr-xr-x 2 root root 4096 Apr  3 18:07 etc/
drwxr-xr-x 2 root root 4096 Apr  3 18:07 logs/
drwxr-xr-x 2 root root 4096 Apr  3 18:07 run/

添加配置文件

把源码包中的redis.conf移动到/apps/redis/etc

cp /apps/redis-6.2.6/redis.conf /apps/redis/etc/

root@zhao:/apps/redis# cp /apps/redis-6.2.6/redis.conf /apps/redis/etc/
root@zhao:/apps/redis# ll /apps/redis/etc/
total 100
drwxr-xr-x 2 root root  4096 Apr  3 18:15 ./
drwxr-xr-x 7 root root  4096 Apr  3 18:14 ../
-rw-r--r-- 1 root root 93724 Apr  3 18:15 redis.conf

修改配置文件

vim /apps/redis/etc/redis.conf

root@zhao:/apps/redis/etc# vim /apps/redis/etc/redis.conf
74 bind 127.0.0.1 -::1		修改为	bind 192.168.66.140		#绑定IP地址，其他机器可以通过此IP访问redis
98 port 6379											#端口号
257 daemonize no			修改为daemonize yes			#是否为前台启动
289 pidfile /apps/redis/run/redis_6379.pid				   #pid文件存放的位置，可以改
302 logfile "/apps/redis/logs/redis-6379.log"			   #redis存放的日志文件
327 databases 16										#默认redis数据库提供的数据库数量，16够用
454 dir ./					修改为dir /apps/redis/data		#redis数据库产生的目录
901 requirepass foobared   	  修改为requirepass 123456		 #redis密码启动

添加profile中

vim /etc/profile

root@zhao:/apps/redis# vim /etc/profile
export PATH=/apps/redis/bin:$PATH

root@zhao:/apps/redis# source /etc/profile

创建启动账号

groupadd -g 1000 redis && useradd -u 1000 -g 1000 redis

root@zhao:/apps/redis/etc# groupadd -g 1001 redis && useradd -u 1001 -g 1001 redis

修改属主属组

chown redis:redis /apps/redis -R

root@zhao:/apps/redis/logs# chown redis:redis /apps/redis -R

启动redis

用redis用户启动

sudo -u redis /apps/redis/bin/redis-server /apps/redis/etc/redis.conf

sudo -u redis /apps/redis/bin/redis-server /apps/redis/etc/redis.conf

这是用root账号启动

redis-server /apps/redis/etc/redis.conf

root@zhao:/apps/redis# ss -tnl
State          Recv-Q          Send-Q        Local Address:Port          Peer Address:Port    
LISTEN         0               128           127.0.0.53%lo:53            0.0.0.0:*
LISTEN         0               128           0.0.0.0:22                  0.0.0.0:*
LISTEN         0               511           192.168.66.140:6379         0.0.0.0:*
LISTEN         0               128           [::]:22                     [::]:*

设置开启自启

通过用rc.local设置开启启动

vim /etc/rc.local
#!/bin/bash
sudo -u redis /apps/redis/bin/redis-server /apps/redis/etc/redis.conf
chmod +x /etc/rc.local
systemctl start rc.local

进入redis

redis-cli [参数]

参数：

-u 指定主机名，配置文件中bind中的用户

-p 指定指定端口号

一台主机启多个redis实力

复制一个配置文件，修改一下配置文件名和里边端口号，然后在启动的时候指定新的配置文件，这样就可以启动两个redis了。

1、cd /apps/redis/etc/
2、cp redis.conf redis-6380.conf
3、mv redis.conf redis-6379.conf
4、vim redis-6380.conf 
	修改port 6380
	:%s/6379/6380/g			#执行这一条命令就行
5、/apps/redis/bin/redis-server /apps/redis/etc/redis-6379.conf		#启动6379端口的redis服务
6、/apps/redis/bin/redis-server /apps/redis/etc/redis-6380.conf		#启动6380端口的redis服务
