Redis(一)安装使用

Redis的安装使用

安装

wget http://download.redis.io/releases/redis-5.0.8.tar.gz
tar -xf redis-5.0.8.tar.gz
cd redis-5.0.8
make
src/redis-server redis.conf #启动,如果需要后台启动需要修改redis.conf -> daemonize yes

若环境中没有gcc需要先安装 yum install gcc

若make时出现 fatal error: jemalloc/jemalloc.h: No such file or directory 错误,这是由于redis默认MALLOC=jemalloc 修改为 make MALLOC=libc

密码设置

  • 使用配置文件进行设置密码

    #打开redis.conf配置文件
    vim redis.conf
    #找到requirepass配置,取消注释,修改为自己的密码
    requirepass 123456
    #重启redis即可生效
    
  • 使用命令方式设置密码**(重启后失效)**

    #进入到redis客户端
    [root@centos7lzj redis-5.0.8]# src/redis-cli 
    #查看密码
    127.0.0.1:6379> config get requirepass
    1) "requirepass"
    2) ""
    #设置密码
    127.0.0.1:6379> config set requirepass 123456
    OK
    #此时密码会立即生效,需要验证,否则报(error) NOAUTH Authentication required.
    127.0.0.1:6379> config get requirepass
    (error) NOAUTH Authentication required.
    #验证
    127.0.0.1:6379> auth 123456
    OK
    #再次查看密码
    127.0.0.1:6379> config get requirepass
    1) "requirepass"
    2) "123456"
    
  • 登录(auth password)

    #进入redis客户端
    [root@centos7lzj redis-5.0.8]# src/redis-cli 
    #尝试ping
    127.0.0.1:6379> ping
    (error) NOAUTH Authentication required.
    #此时无权限,登录
    127.0.0.1:6379> auth 123456
    OK
    #再次ping
    127.0.0.1:6379> ping
    PONG
    

开启远程连接

#打开配置文件redis.conf
#注释bind配置
