# 概述 #

Redis是一款开源的基于内存的**数据结构化存储工具**，被广泛应用为数据库，缓存以及消息代理,详情见[官网][Link 1]。

# 安装 #

下面记录如何在Linux发行版Ubuntu18.04上安装配置Redis的方法。

## 更新仓库 ##

sudo apt update

## 运行安装命令 ##

sudo apt install redis-server

若期间有询问的话，选择`Y`继续

## 配置 ##

使用vim打开redis配置文件

sudo vim /etc/redis/redis.conf

找到

supervised no

修改为：

supervised systemd

上面的步骤是为了可以对redis使用`systemctl`命令

## 解决报错（可选，如果没有报错就万事大吉了） ##

*  安装过程有可能报如下错误

Job for redis-server.service failed because a timeout was exceeded.
    See "systemctl status redis-server.service" and "journalctl -xe" for details.
    invoke-rc.d: initscript redis-server, action "start" failed.
    ● redis-server.service - Advanced key-value store
       Loaded: loaded (/lib/systemd/system/redis-server.service; disabled; vendor preset: enabled)
       Active: activating (auto-restart) (Result: timeout) since Sun 2021-01-03 17:04:06 CST; 9ms ago

**解决方法：**

打开redis.service文件

sudo vim /etc/systemd/system/redis.service

在

ExecStop=/bin/kill -s TERM $MAINPID

下面添加一行

ExecStartPost=/bin/sh -c "echo $MAINPID > /var/run/redis/redis.pid"

载入并重启redis

sudo systemctl daemon-reload
    sudo systemctl restart redis

**注意**：  
如果使用`systemctl`命令时报如下错的话

Unit redis.service could not be found.

就需要使用如下命令创建一个symlink

sudo systemctl enable redis-server

输出如下结果说明成功了：

Synchronizing state of redis-server.service with SysV service script with /lib/systemd/systemd-sysv-install.
    Executing: /lib/systemd/systemd-sysv-install enable redis-server
    Created symlink /etc/systemd/system/redis.service → /lib/systemd/system/redis-server.service.

重新执行载入并重启的命令

sudo systemctl daemon-reload
    sudo systemctl restart redis

*  重启后使用如下命令查看redis状态

sudo systemctl status redis

如果报类似如下错误

● redis-server.service - Advanced key-value store
       Loaded: loaded (/lib/systemd/system/redis-server.service; enabled; vendor preset: enabled)
       Active: failed (Result: protocol) since Sun 2021-01-03 18:07:00 CST; 1min 3s ago

可能是你的机器不支持IPV6

**解决方法：**

打开redis配置文件，

sudo vim /etc/redis/redis.conf

找到

bind: bind 127.0.0.1 ::1

修改为

bind 127.0.0.1

后，重启redis

sudo systemctl restart redis

# 连接 #
