Linux下安装Redis

编译安装工作：

#下载redis安装包
wget http://download.redis.io/releases/redis-4.0.10.tar.gz
#解压安装包
tar -zxvf redis-4.0.10.tar.gz -C /usr/local/
#重命名为redis
mv /usr/local/redis-4.0.10 /usr/local/redis
#进入安装目录
cd /usr/local/redis
#编译并安装
make && make install

修改redis.conf配置：

#进入配置文件所在目录
cd /usr/local/redis
#开启守护进程模式（即允许后台运行）
sed -i 's/daemonize no/daemonize yes/g' redis.conf
#关闭protected-mode模式，使外部网络可以直接访问（生产慎用）
sed -i 's/protected-mode yes/protected-mode no/g' redis.conf
#设置redis连接密码（生产建议使用密码）
sed -i 's/# requirepass foobared/requirepass 123456/g' redis.conf
#对过期事件进行通知发送（可用于token过期提醒）
sed -i 's/notify-keyspace-events ""/notify-keyspace-events Ex/g' redis.conf

编写Redis启动脚本：

#创建redis脚本
vi /etc/init.d/redisd
#向脚本中写入以下内容：

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

### BEGIN INIT INFO

# 启动服务

        while [ -x /proc/${PID} ]
        do
            echo "Waiting for Redis to shutdown ..."
            sleep 1
        done
        echo "Redis stopped"
    fi
}
# 启动状态
status(){
    if [ -f $PIDFILE ]
    then
        PID=$(cat $PIDFILE)
        echo "$PIDFILE is running，pid=${PID}"
    else
        echo "$PIDFILE is not running"
    fi
}

case "$1" in
    start)
        start
        ;;
    stop)
        stop
        ;;
    status)
        status
        ;;
    restart)
        stop
        sleep 1s
        start
        ;;
    *)
        echo "Please use start|stop|restart|status as first argument"
        ;;
esac

启动Redis服务（需要赋权限chmod 755 /etc/init.d/redisd）：

#设置开机自启动 chkconfig redisd on
#查看开机自启动 chkconfig --list | grep redisd
#启动redis服务 service redisd start
#停止redis服务 service redisd stop
#重启redis服务 service redisd restart
#查看redis服务 service redisd status

注：要使远程能够登录访问，还需开启防火墙和配置安全组规则（阿里云服务器），可参考https://www.cnblogs.com/54hsh/p/13355413.html
