2.下载Redis
Redis官方下载链接
下载安装包：
wget http://download.redis.io/releases/redis-5.0.7.tar.gz
3.解压/编译/安装
- 先准备个文件夹 /usr/local/redis 将解压后的文件存放在该目录
tar -zxvf redis-5.0.7.tar.gz -C /usr/local/redis
- 等待解压完成 cd 到/usr/local/redis目录下 查看解压后的文件
- cd到redis-4.0.9目录下 运行编译命令
make MALLOC=libc
- 等待编译完成 cd 到redis-4.0.9下的src目录 运行安装命令
make install
- 等待安装完成 会自动在/usr/local/bin目录下生成redis相关的可执行文件 可以cd到该目录下查看一下
4. 启动Redis（临时方式）
我们以后也可以在该目录下用./redis-server来启动redis 也可以在刚刚的src目录下运行./redis-server
无论用哪个目录下的./redis-server都可以启动redis 我们来试一下
/usr/local/bin目录 启动redis【./redis-server】
/usr/local/redis/redis-5.0.7/src 目录启动redis 【./redis-server】
[root@instance-6uz2q7zs bin]# ./redis-server

15886:C 02 Feb 2020 14:53:32.730 # Redis version=5.0.7, bits=64, commit=00000000, modified=0, pid=15886, just started
15886:C 02 Feb 2020 14:53:32.730 # Warning: no config file specified, using the default config. In order to specify a config file use ./redis-server /path/to/redis.conf

如上图 redis就成功启动了 当然这种并不是后台启动(守护线程)的方式 因为退出该窗口redis就关闭了 接下来我来教大家如何以守护线程启动redis
5.守护线程(后台启动)方式启动redis
首先按ctrl+c退出该窗口 我们cd 到redis的解压目录下 我们可以看到有个redis.conf文件 这个文件是redis的配置文件
vim 打开redis.conf文件
我们可以看到有个daemonize配置项 这个就是后台启动的意思 将no改成yes即可 修改完之后 保存退出(修改配置文件并保存退出这里我就不介绍了哈)
5.1 启动Redis（方式1）
这时候我们再去启动 要知道启动文件在src目录下 cd 到src目录 运行如下命令
./redis-server ../redis.conf
运行该目录下的启动文件redis-server 再将上级目录下的redis.conf配置文件带进去 就可成功后台启动redis了
5.1 启动Redis（方式2）
cd redis-5.0.7目录下，将redis.conf文件复制到/usr/local/bin目录下启动redis
cp redis.conf /usr/local/bin
启动Redis
[root@zzy bin]# ./redis-server redis.conf
32483:C 25 Feb 2020 12:41:01.729 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
32483:C 25 Feb 2020 12:41:01.729 # Redis version=5.0.7, bits=64, commit=00000000, modified=0, pid=32483, just started
32483:C 25 Feb 2020 12:41:01.729 # Configuration loaded
[root@zzy bin]# pwd
/usr/local/bin
修改 /usr/local/bin下的redis.conf配置文件可以设置
- 守护线程启动
- 远程链接redis
- 设置redis密码
这时候 我们可以去看一下redis是否启动成功
如上图 redis我们成功后台启动了
到此完成
若关闭redis 可以直接 kill -9 16582
6 远程连接redis
6.1 修改redis配置文件
找到redis的安装目录
vim redis.conf
bind 0.0.0.0
protected-mode no
关闭redis后重启redis
远程连接Redis 成功
7. 设置Redis密码
在服务器上，这里以linux服务器为例，为redis配置密码。
7.1 第一种方式 （临时方式）
（当前这种linux配置redis密码的方法是一种临时的，如果redis重启之后密码就会失效）
（1）首先进入redis，如果没有开启redis则需要先开启：
[root@iZ94jzcra1hZ bin]# redis-cli -p 6379
127.0.0.1:6379>
（2）查看当前redis有没有设置密码：
127.0.0.1:6379> config get requirepass
1) "requirepass"
2) ""
（3）为以上显示说明没有密码，那么现在来设置密码：
127.0.0.1:6379> config set requirepass abcdefg
OK
127.0.0.1:6379>
（4）再次查看当前redis就提示需要密码：
127.0.0.1:6379> config get requirepass
(error) NOAUTH Authentication required.
127.0.0.1:6379>
7.2 第二种方式 （永久方式）
需要永久配置密码的话就去redis.conf的配置文件中找到requirepass这个参数，如下配置：
修改redis.conf配置文件
vim redis.conf
查找requirepass foobared（Esc ：/requirepass foobared），把前面的注释去掉，
将foobared改成自己的密码
#requirepass foobared
requirepass 123 指定密码123
保存后重启redis就可以了
7.3 redis-cli连接redis
[root@iZ2ze3zda3caeyx6pn7c5zZ bin]# redis-cli
127.0.0.1:6379> keys *
(error) NOAUTH Authentication required.
#使用auth password验证密码
127.0.0.1:6379> auth 123 //指定密码
OK
127.0.0.1:6379> keys *
1) "a"
2) "cit"
3) "clist"
4) "1"
#客户端使用config get requirepass命令查看密码
127.0.0.1:6379> config get requirepass
1) "requirepass"
2) "123"
