Centos7安装Redis

一、安装gcc依赖

由于 redis 是用 C 语言开发，安装之前必先确认是否安装 gcc 环境（gcc -v），如果没有安装，执行以下命令进行安装

yum install -y gcc

二、下载并解压安装包

wget https://github.com/antirez/redis/archive/5.0.3.tar.gz

tar -zxvf 5.0.3.tar.gz

三、cd切换到redis解压目录下，执行编译

cd redis-5.0.3

make

四、安装并指定安装目录

make install PREFIX=/usr/local/redis

五、启动服务

5.1前台启动

cd /usr/local/redis/bin/

./redis-server

5.2后台启动

从 redis 的源码目录中复制 redis.conf到 redis 的安装目录

cp /root/redis-5.0.3/redis.conf /usr/local/redis/bin/

修改 redis.conf文件，把 daemonize no 改为 daemonize yes

vim redis.conf

# By default Redis does not run as a daemon. Use 'yes' if you need it.
# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
daemonize yes

后台启动

./redis-server redis.conf

ps -ef | grep redis

六、设置开机启动

添加开机启动服务

vim /etc/systemd/system/redis.service

[Unit]
Description=redis-server
After=network.target

[Service]
Type=forking
ExecStart=/usr/local/redis/bin/redis-server /usr/local/redis/bin/redis.conf
PrivateTmp=true

[Install]
WantedBy=multi-user.target

注意：ExecStart配置成自己的路径

设置开机启动

systemctl daemon-reload

systemctl start redis.service

systemctl enable redis.service

创建 redis 命令软链接

ln -s /usr/local/redis/bin/redis-cli /usr/bin/redis

测试 redis

redis

服务操作命令

systemctl start redis.service   #启动redis服务

systemctl stop redis.service   #停止redis服务

systemctl restart redis.service   #重新启动服务

systemctl status redis.service   #查看服务当前状态

systemctl enable redis.service   #设置开机自启动

systemctl disable redis.service   #停止开机自启动

七、设置远程连接访问密码

vim redis.conf

在配置文件中配置requirepass

requirepass pasd201314

远程连接

import redis

host = '47.99.156.219'
port = 6379
password = "NewHopeData@123"
r = redis.Redis(host = host, port = port,password=password)

if __name__ == '__main__':
  r.set("868474045748926","{'id': 168111142, 'deviceType': 2, 'batteryLevel': 75, 'signalStrength': 21, 'sampleData': '410677', 'passNum': 0, 'alarmType': '2', 'unit': 'm', 'dataBody': None, 'time': '2020-11-04 14:17:09.0', 'offlineTime': None, 'lon': None, 'lat': None, 'address': None, 'value': '1.0677', 'sendDate': None, 'status': None, 'pressure': None, 'name': None, 'deviceName': None, 'deviceModelName': None, 'imei': '868474045748926'}")
  for key in r.keys():
      print(key.decode())
      print(r.get(key).decode())
