一、redis单机安装

linux安装：源来自官网 Download | Redis，版本选择7.0 stable

# 1.将Redis安装包上传到Linux
# 2.解压安装包，命令：
tar -zxvf redis-7.0.5.tar.gz

# 3.安装Redis的依赖环境gcc，命令：
yum install gcc-c++

# 4.不指定prefix会编译到/usr/local/bin，指定后删除/usr/local/redis，方便删除redis
cd /root/redis-7.0.5
make && make PREFIX=/usr/local/redis install

服务指令

# 设置开机自启动：
systemctl enable redis

# 关闭开机自动启动：
systemctl disable redis

# 启动redis服务：
systemctl start redis

# 停止服务：
systemctl stop redis

# 重新加载redis配置文件：
systemctl reload redis

# 查看所有已启动的服务：
systemctl list-units --type=service

#查看服务当前状态：
systemctl status redis

二、简易测试

# 启动服务
redis-server

# 测试
redis-cli
127.0.0.1:6379> ping
PONG
127.0.0.1:6379> keys *
(empty array)
redis> set foo bar
OK
redis> get foo
"bar"

三、生产配置

这里演示的是两台干净主机的初识配置，如果是主从不一致，需要重新同步具体看下一节

配置文件

# 采用配置文件启动
redis-server /root/redis-7.0.5/redis.conf

# 关于配置文件的主要配置
daemonize yes # 以守护进程方式启动
supervised systemd # 可以跟systemd进程进行交互

#其他配置供参考
bind 0.0.0.0 #任意ip都可以连接
protected-mode no #关闭保护，允许非本地连接
port 6379 #端口号
pidfile /var/run/redis_6379.pid #进程守护文件，就是存放该进程号相关信息的地方
dir /usr/loacl/redis-6.0.10/data/ #db等相关目录位置
logfile "/usr/local/redis-6.0.10/logs/redis_6379.log"
appendonly yes #开启日志形式
requirepass 123456 #密码

设置开机自启

客户端

可以搜索安装 another redis desktop manager，原版已经收费了~
