Redis安装

一顿操作，下载安装，启动，删除安装包

#下载到local下
cd /usrl/local
wget http://download.redis.io/releases/redis-4.0.9.tar.gz
#解压安装包
tar xzf redis-4.0.9.tar.gz
cd redis-4.0.9
#编译安装
make
sudo make install
#使用默认配置启动redis
./src/redis-server ../redis.conf
#删除安装包
cd ..
rm redis-4.0.9.tar.gz

其他常用命令
停止redis
./src/redis-cli -h 127.0.0.1 -p 6379 shutdown
设置了密码停止
./src/redis-cli -a "密码" -h 127.0.0.1 -p 6379 shutdown

直接用默认文件启动，会出现界面，而且窗口不能关闭，换一种方式

#复制一份配置文件
cd /usr/local/redis-4.0.9
cp redis.conf ./use.conf
vim use.conf
将daemonize 配置成yes 作为守护进程运行
保存之后，指定配置文件启动
./src/redis-server ./use.conf 

使用客户端连接redis，连接之后，如果有密码要加上后面那句

redis.cli -p 127.0.0.1 -h 6319
auth 密码

在redis-4.0.9下面发现了一个utils目录，进去一看发现有惊喜，里面有个redis_init_script的脚本，里面定义了开启和关闭的脚本。稍微修改下

#!/bin/sh./src/redis-cli -h 127.0.0.1 -p 6379 shutdown
REDISPORT=6379
EXEC=/usr/local/bin/redis-server
CLIEXEC=/usr/local/bin/redis-cli
PIDFILE=/var/run/redis_${REDISPORT}.pid
#CONF="/etc/redis/${REDISPORT}.conf"
CONF="/usr/local/redis-4.0.9/use.conf"
case "$1" in
    start)
        if [ -f $PIDFILE ]
        then
                echo "$PIDFILE exists, process is already running or crashed"
        else
                echo "Starting Redis server..."
                $EXEC $CONF
        fi
        ;;
    stop)
        if [ ! -f $PIDFILE ]
        then
                echo "$PIDFILE does not exist, process is not running"
        else
                PID=$(cat $PIDFILE)
                echo "Stopping ..."
                $CLIEXEC -a "123456" -p $REDISPORT shutdown
                while [ -x /proc/${PID} ]
                do
                    echo "Waiting for Redis to shutdown ..."
                    sleep 1
                done
                echo "Redis stopped"
        fi
        ;;
    restart)
        if [ ! -f $PIDFILE ]
        then
                echo "$PIDFILE does not exist, process is not running"
        else
                PID=$(cat $PIDFILE)
                echo "Stopping ..."
                $CLIEXEC -a "123456" -p $REDISPORT shutdown
                while [ -x /proc/${PID} ]
                do
                    echo "Waiting for Redis to shutdown ..."
                    sleep 1
                done
                echo "Redis stopped"
        fi
        if [ -f $PIDFILE ]
        then
                echo "$PIDFILE exists, process is already running or crashed"
        else
                echo "Starting Redis server..."
                $EXEC $CONF
        fi
        ;;
    *)
        echo "Please use start or stop as first argument"
        ;;
esac

然后将此文件复制到外层

 cp redis_init_script ../redis.sh

接下来启动，停止，重启就变成下面这样了

由于每次连接redis去测试都要redis -cli -a 密码 -h 127.0.0.1 -p 6379，觉得比较麻烦，所以在创建了个连接脚本。

cd /
mkdir script
cd script
vim redis-connect.sh

编写脚本如下：

#!/bin/bash
cd /usr/local/redis-4.0.9
redis-cli -a 123456 -h 127.0.0.1 -p 6379

接下来就是自由发挥时间了。。。
