## 查看redis版本信息
hc@uos:~$ redis-server -v
Redis server v=5.0.7 sha=00000000:0 malloc=jemalloc-5.2.1 bits=64 build=636cde3b5c7a3923

## 使用客户端登录连接redis 默认端口号 6379
hc@uos:~$ redis-cli -h localhost -p 6379
localhost:6379> get n
"18"
localhost:6379> exit
hc@uos:~$ redis-cli
127.0.0.1:6379> get n
"18"
127.0.0.1:6379> ping
PONG

901 # requirepass foobared 修改为取消注释，设置密码
requirepass 123456

#/usr/local/redis/redis_6379.conf

安装启动服务

image-20211018163717940

#别名
$ alias redis='/usr/local/redis/bin/redis-cli'

#redis客户端登录 -h 主机 -p 端口 -n 数据库代号 -a 
$ redis -h localhost  -p 6379 -n 0 -a 123456

redis安装步骤

1、sudo apt install gcc make pkg-config -y
2、wget https://download.redis.io/releases/redis-6.2.6.tar.gz
3、tar -zxvf redis-6.2.6.tar.gz
4、cd redis-6.2.6 
5、sudo make PREFIX=/usr/local/redis install
   #编译安装后，可执行的程序在
   /usr/local/redis/bin 目录 redis-server 服务器  redis-cli客户端
6、sudo cp redis.conf /usr/local/redis 
   #复制配置文件到 /usr/local/redis
7、sudo ln -s /usr/local/redis/bin/redis-cli /usr/bin/redis
   #建立软连接，就是快捷方式，可以直接输入redis客户端登录服务器
   #cd /usr/local/redis/bin 目录下
   # ./redis-cli 才能登录
8、编辑sudo vim /usr/local/redis/redis.conf 
	75 bind 127.0.0.1 -::1 注释此行
	#bind 127.0.0.1 -::1

	94 protected-mode yes 修改为
	protected-mode no

	98 port 6379 此行不用修改

	257 daemonize no 修改为
	daemonize yes

	289 pidfile /var/run/redis_6379.pid 此行不变和/etc/systemd/system/redis.service内容一样

	302 logfile "" 修改为
	logfile "/usr/local/redis/logs/redis.log"

	431 dbfilename dump.rdb #此行不变，为数据库名

	454 #dir ./ 修改为
	dir /usr/local/redis/data/

	901 # requirepass foobared 修改为取消注释，设置密码
	requirepass 123456    

9、建立服务文件 sudo vim /etc/systemd/system/redis.service 
	#建立文件 sudo vim /etc/systemd/system/redis.service 
	#内容如下：
	[Unit]
	Description=Advanced key-value store
	After=network.target

	[Service]
	Type=forking
	ExecStart=/usr/local/redis/bin/redis-server /usr/local/redis/redis.conf
	ExecStop=/bin/kill -s TERM $MAINPID
	PIDFile=/var/run/redis_6379.pid
	Restart=always
	RestartSec=5s
	Restart=on-failure

	[Install]
	WantedBy=multi-user.target
	Alias=redis.service

10、sudo systemctl enable redis.service  #将redis服务器设置开机启动 
    sudo systemctl start redis #直接手动启动redis服务
    sudo systemctl status redis #可以查看redis服务状态
    #查看redis相关的进程
    ps -ef | grep redis
	root         826       1  0 12月09 ?      00:01:19 /usr/local/redis/bin/redis-server *:6379
	root        1348       1  0 12月09 ?      00:01:21 ./redis-server *:6380
	hc      24789   24774  0 10:55 pts/0    00:00:00 grep --color=auto redis

11、redis 回车 默认是本机 localhost 端口6379 -n 0
    127.0.0.1>ping
    PONG

    127.0.0.1>shutdown #给服务器发送一个关闭命令

    #临时关闭服务，下次开机redis自动启动
    sudo systemctl stop redis
