Centos下redis的安装

一、前置依赖安装

yum install gcc-c++

二、redis的安装

1.安装

redis官网下载地址: http://download.redis.io/releases/

# 下载
cd /usr/local/src
wget http://download.redis.io/releases/redis-6.2.5.tar.gz
tar -zxvf redis-6.2.5.tar.gz 
cd redis-6.2.5/
# 编译安装
# 安装指定/usr/local/redis
make PREFIX=/usr/local/redis install
make install
# redis路径
cd /usr/local/redis
mkdir conf
mkdir data
mkdir logs
cp /usr/local/src/redis-6.2.5/redis.conf /usr/local/redis/conf/

2.配置

redis.conf 配置：

# 远程访问
bind 0.0.0.0
# 是否开启后台运行
daemonize yes
# 是否开启保护模式，默认开启。要是配置里没有指定bind和密码。开启该参数后，redis只会本地进行访问，拒绝外部访问。要是开启了密码和bind，可以开启。否则最好关闭，设置为no。

3.命令

配置conf后启动redis:

# 服务端启动
/usr/local/redis/bin/redis-server /usr/local/redis/conf/redis_6379.conf
##################################
# 客户端启动
/usr/local/redis/bin/redis-cli 
127.0.0.1:6379> auth 密码
OK
127.0.0.1:6379> get *
(nil)
127.0.0.1:6379> 

4.目录结构

启动后的目录结构:

tree redis/
redis/
├── bin
│   ├── redis-benchmark
│   ├── redis-check-aof -> redis-server
│   ├── redis-check-rdb -> redis-server
│   ├── redis-cli
│   ├── redis-sentinel -> redis-server
│   └── redis-server
├── conf
│   ├── redis_6379.conf
│   └── redis.conf
├── data
│   ├── appendonly_6379.aof
│   └── dump_6379.rdb
├── logs
│   └── redis.log
└── redis.pid

4 directories, 12 files

5.防火墙

防火墙开放6379端口

# 查询防火墙已开放端口
firewall-cmd --list-port
# 设置开放80端口
firewall-cmd --zone=public --add-port=6379/tcp --permanent
# 重启防火墙，生效设置
firewall-cmd --reload
