1.下载

https://redis.io/download  cd /usr/local/src  wget -c http://download.redis.io/releases/redis-3.2.6.tar.gz

2.解压

cd /usr/local/src  tar xzf redis-3.2.6.tar.gz

3.编译

cd /usr/local/src/redis-3.2.6make

#若出现错误则说明未安装gcc

yum install gcc && make MALLOC=libccd /usr/local/src/redis-3.2.6 &&  make

4.创建redis目录

mkdir -p /usr/local/redis

5.复制主要配置文件到新文件夹

cp /usr/local/src/redis-3.2.6/src/redis-server /usr/local/redis/  cp /usr/local/src/redis-3.2.6/src/redis-cli /usr/local/redis/  cp /usr/local/src/redis-3.2.6/redis.conf /usr/local/redis/

6.开启后台运行

vim /usr/local/redis/redis.conf  修改redis.conf文件中的daemonize no为daemonize yes并保存

7.创建redis命令软连接

ln -s /usr/local/redis/redis-cli /usr/bin/redis  在任意命令行执行redis

8.添加开机启动服务

vim /etc/systemd/system/redis-server.service

粘贴以下内容

[Unit]  Description=The redis-server Process Manager  After=syslog.target network.target      [Service]  Type=simple  PIDFile=/var/run/redis_6379.pid  ExecStart=/usr/local/redis/redis-server /usr/local/redis/redis.conf  ExecReload=/bin/kill -USR2 $MAINPID  ExecStop=/bin/kill -SIGINT $MAINPID      [Install]  WantedBy=multi-user.target

9.设置开机启动

systemctl daemon-reload  systemctl start redis-server.service  systemctl enable redis-server.servic

10.检查是否安装成功

ps -A|grep redis

11.连接登录

#交互式

  #redis-cli -h {host} -p {port}  $redis-cli -h 127.0.0.1 -p 6379  127.0.0.1：6379>set hello world  OK  127.0.0.1：6379>get hello  "world"

#命令式

  #redis-cli -h {host} -p {port} {command}  $redis-cli -h 127.0.0.1-p 6379 get hello  "world"

12.永久设置Redis密码

vim /etc/redis.conf  #在配置文件中有个参数：requirepass 这个就是配置redis访问密码的参数；  #比如 requirepass test123；

需重启Redis才能生效

13.临时设置Redis密码

redis 127.0.0.1:6379> config set requirepass test123

#查询密码：

redis 127.0.0.1:6379> config get requirepass  (error) ERR operation not permitted

#密码验证：

redis 127.0.0.1:6379> auth test123  OK

#再次查询：

redis 127.0.0.1:6379> config get requirepass  1) "requirepass"  2) "test123"

14.登陆有密码的Redis

redis-cli -p 6379 -a test123

15.先登陆后验证

redis-cli -p 6379  redis 127.0.0.1:6379> auth test123  OK

16.开启后台运行

将redis.conf中的"daemonize no"为"daemonize yes"并保存,重启redis生效。
