CentOS8系统Redis单机安装

安装依赖包

sudo yum -y install gcc automake autoconf libtool make tcl

安装Redis

wget http://download.redis.io/redis-stable.tar.gz
sudo cp redis-stable.tar.gz /opt
cd /opt
sudo tar zxvf redis-stable.tar.gz
sudo mv redis-stable redis
cd /opt/redis
make
make test
sudo make install

配置Redis

创建Redis配置目录和数据目录

sudo mkdir /etc/redis
sudo mkdir -p /opt/redis-data/6379

复制启动脚本

sudo cp utils/redis_init_script /etc/init.d/redis

编辑启动脚本

sudo vi /etc/init.d/redis

根据情况修改REDISPORT。pid文件路径和配置文件名取决于端口号。

复制配置文件

sudo cp /opt/redis/redis.conf /etc/redis/6379.conf

修改配置文件

sudo vi /etc/redis/6379.conf

更改以下配置

# 后台启动
daemonize yes
# 设置端口
port 6379
# 设置pidfile
pidfile /var/run/redis_6379.pid
# 注释bind，允许远程访问
# bind 127.0.0.1
# 修改密码
requirepass 您的密码
# 关闭protected-mode模式，允许外网访问
protected-mode no
# 设置日志级别
loglevel notice
# 设置日志文件
logfile /var/log/redis_6379.log
# 设置redis数据存储目录
dir /opt/redis-data/6379

如果redis有设置密码，则/etc/init.d/redis需要增加密码：

#!/bin/sh
#
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.
