安装单机版redis

$ wget http://download.redis.io/releases/redis-4.0.9.tar.gz
$ tar xzf redis-4.0.9.tar.gz
$ cd redis-4.0.9
$ make && make test && make install

redis作为daemon进程去运行的，每次系统启动，redis进程一起启动

拷贝启动脚本

• redis utils目录下，有个redis_init_script脚本

cp utils/redis_init_script /etc/init.d/redis_6379

• 将redis_init_script脚本拷贝到linux的/etc/init.d目录中，重命名为redis_6379，6379是我们希望这个redis实例监听的端口号。

修改端口

• 修改redis_6379脚本的第6行的REDISPORT，设置为相同的端口号（默认就是6379）

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

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"

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 -p $REDISPORT shutdown
                while [ -x /proc/${PID} ]
                do
                    echo "Waiting for Redis to shutdown ..."
                    sleep 1
                done
                echo "Redis stopped"
        fi
        ;;
    *)
        echo "Please use start or stop as first argument"
        ;;
esac

创建配置目录和持久化目录

创建两个目录：/etc/redis（存放redis的配置文件），/var/redis/6379（存放redis的持久化文件）

mkdir -p /etc/redis
mkdir -p /var/redis/6379

• 修改redis配置文件（默认在根目录下，redis.conf），拷贝到/etc/redis目录中，修改名称为6379.conf

cp redis.conf /etc/redis/6379.conf

• 修改redis.conf中的配置参数

daemonize   yes                         让redis以daemon进程运行
pidfile     /var/run/redis_6379.pid     设置redis的pid文件位置
port        6379                        设置redis的监听端口号
dir         /var/redis/6379             设置持久化文件的存储位置

• 启动redis，确认redis进程是否启动

cd /etc/init.d
chmod 777 redis_6379
./redis_6379 start

root@VM-0-10-ubuntu:/etc/init.d# ./redis_6379 start
Starting Redis server...

root      3120 31412  0 09:52 pts/0    00:00:00 grep --color=auto redis

• 让redis跟随系统启动自动启动

root@VM-0-10-ubuntu:/etc/init.d# update-rc.d redis_6379 defaults 
update-rc.d: warning: /etc/init.d/redis_6379 missing LSB information
update-rc.d: see

   /etc/rc5.d/S20redis_6379 -> ../init.d/redis_6379

centos在redis_6379脚本中，最上面，加入两行注释

# chkconfig:   2345 90 10
# description:  Redis is a persistent key-value database

命令行执行 ：chkconfig redis_6379 on

redis-cli SHUTDOWN，连接本机的6379端口停止redis进程
redis-cli -h 127.0.0.1 -p 6379 SHUTDOWN，制定要连接的ip和端口号
redis-cli PING，ping redis的端口，看是否正常
redis-cli，进入交互式命令行
