redis安装

1.环境准备

//环境准备
systemctl stop firewalld
systemctl disable firewalld
setenforce 0
sed -i 's/enforcing/disabled/' /etc/selinux/config

修改系统内核

vim /etc/sysctl.conf

sysctl -p

2. 安装redis

安装环境

yum install -y gcc gcc-c++ make

解压 

tar zxvf /opt/redis-7.0.9.tar.gz -C /opt/

编译

tar zxvf /opt/redis-7.0.9.tar.gz -C /opt/
cd /opt/redis-7.0.9
make
make PREFIX=/usr/local/redis install

 创建redis工作目录

mkdir /usr/local/redis/{conf,log,data}

cp /opt/redis-7.0.9/redis.conf /usr/local/redis/conf/

useradd -M -s /sbin/nologin redis
chown -R redis.redis /usr/local/redis/

环境变量

vim /etc/profile 

PATH=$PATH:/usr/local/redis/bin		#增加一行
source /etc/profile

修改配置文件 

vim /usr/local/redis/conf/redis.conf
bind 127.0.0.1 192.168.2.107					#87行，添加 监听的主机地址
protected-mode no					#111行，将本机访问保护模式设置no。如果开启了，那么在没有设定bind ip且没有设密码的情况下，Redis只允许接受本机的响应
port 6379										#138行，Redis默认的监听6379端口
daemonize yes									#309行，设置为守护进程，后台启动
pidfile /usr/local/redis/log/redis_6379.pid		#341行，指定 PID 文件
logfile "/usr/local/redis/log/redis_6379.log"	#354行，指定日志文件
dir /usr/local/redis/data						#504行，指定持久化文件所在目录
requirepass abc123								#1037行，增加一行，设置redis密码

定义systemd服务管理脚本

vim /usr/lib/systemd/system/redis-server.service
[Unit]
Description=Redis Server
After=network.target

[Service]
User=redis
Group=redis
Type=forking
TimeoutSec=0
PIDFile=/usr/local/redis/log/redis_6379.pid
ExecStart=/usr/local/redis/bin/redis-server /usr/local/redis/conf/redis.conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

启动服务

systemctl start redis-server
systemctl enable redis-server

netstat -lntp | grep 6379

redis-cli -h 192.168.2.107 -p 6379 -a 'abc123'
