一.Ubuntu 20 里安装 Redis

使用 apt 安装

 apt install redis -y

支持远程连接

修改 /etc/redis/redis.conf

• 修改 bind 127.0.0.1 为 bind 0.0.0.0
• 修改 protected-mode yes 为 protected-mode no

1 # By default, if no "bind" configuration directive is specified, Redis listens
2 # for connections from all the network interfaces available on the server.
3 # It is possible to listen to just one or multiple selected interfaces using
4 # the "bind" configuration directive, followed by one or more IP addresses.
5 #
6 # Examples:
7 #
8 # bind 192.168.1.100 10.0.0.1
9 # bind 127.0.0.1 ::1
10 #
11 # ~~~ WARNING ~~~ If the computer running Redis is directly exposed to the
12 # internet, binding to all the interfaces is dangerous and will expose the
13 # instance to everybody on the internet. So by default we uncomment the
14 # following bind directive, that will force Redis to listen only into
15 # the IPv4 loopback interface address (this means Redis will be able to
16 # accept connections only from clients running into the same computer it
17 # is running).
18 #
19 # IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
20 # JUST COMMENT THE FOLLOWING LINE.
21 # ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
22 # bind 127.0.0.1 # 注释掉这⾏
23 bind 0.0.0.0 # 添加这⾏
24
25 protected-mode no # 把 yes 改成 no

控制 Redis 启动

启动 Redis 服务

 service redis-server start

停止 Redis 服务

service redis-server stop

重启 Redis 服务

service redis-server restart

---

二.Centos

如果是 Centos8 , yum 仓库中默认的 redis 版本就是5.直接yum install 即可

Centos7

使用 yum 安装

首先安装 scl 源, 再安装 redis

yum install centos-release-scl-rh

yum install rh-redis5-redis

创建符号链接

默认安装的目录为 /opt/rh/rh-redis5/root/usr/bin/ , 藏的太深了, 不方便使用. 我们通过符号链接, 把需要用到的关键内容设置到方便使用的目录中.

1. 针对可执行程序设置符号链接

cd /usr/bin
ln -s /opt/rh/rh-redis5/root/usr/bin/redis-server ./redis-server
ln -s /opt/rh/rh-redis5/root/usr/bin/redis-sentinel ./redis-sentinel
ln -s /opt/rh/rh-redis5/root/usr/bin/redis-cli ./redis-cli

2. 针对配置文件设置符号链接

cd /etc/
ln -s /etc/opt/rh/rh-redis5/ ./redis

修改配置文件

1. 设置 ip 地址

 bind 0.0.0.0

2. 关闭保护模式

protected-mode no

3. 启动守护进程

daemonize yes

4. 设置工作目录

先创建工作目录

mkdir -p /var/lib/redis

再在配置文件中, 设置工作目录

dir /var/lib/redis

5. 设置日志目录

先创建日志目录

mkdir -p /var/log/redis/

再在配置文件中, 设置日志目录

logfile /var/log/redis/redis-server.log

启动 redis

 redis-server /etc/redis/redis.conf

停止 redis

先查看到 redis-server 的 pid

ps aux | grep redis

然后通过 kill 命令直接杀死 redis 进程

kill 进程 id
