Redis安装部署

Redis安装部署

一、编译安装

下载、解压

wget http://download.redis.io/releases/redis-3.2.8.tar.gz
tar -zxvf redis-3.2.8.tar.gz
cd  redis-3.2.8

make 编译
编译之前

00-RELEASENOTES  BUGS  CONTRIBUTING  COPYING  deps  INSTALL  Makefile  MANIFESTO  README.md  redis.conf  runtest 

编译完成之后,可以看到解压文件redis-3.0.7 中会有对应的src、conf等文件。

二、部署文件结构

首先为了方便管理,将Redis文件中的conf配置文件和常用命令移动到统一文件中
创建以下文件目录

mkdir -p /usr/local/redis/bin
mkdir -p /usr/local/redis/etc

切换到redis-3.2.8目录,移动redis.conf配置文件:

mv /home/payn/redis-3.2.8/redis.conf /usr/local/redis/etc

继续进入到src目录执行其他文件移动:

mv mkreleasehdr.sh redis-benchmark redis-check-aof redis-check-rdb redis-cli  
redis-sentinel redis-server redis-trib.rb /usr/local/redis/bin

三、配置和启动redis服务

编辑redis.conf

cd /usr/local/redis/etc
vi redis.conf

需要修改的参数

--后台运行
daemonize yes
       
--端口号
port 63700          

--和哪个网卡绑定,和客户端是什么网段没有关系,这里我绑定的是内网网卡,
bind 192.168.25.128

-- AES("https://github.com/Tinywan/Lua-Nginx-Redis/blob/master/Redis/redis-install.md") 加密
-- 结果:b6Pbc42gP8hXPNLzZaDnhREijtn1BSVSIYTkhTXw8SuPGpWZvN5kVpVeEVBdEQDw7M/+EZuDS6FxTOtgD2QrPe6014LPEdv2DY+YSUQZ4cE=

requirepass b6Pbc42gP8hXPNLzZaDnhREijtn1BSVSIYTkhTXw8SuPGpWZvN5kVpVeEVBdEQDw7M/+EZuDS6FxTOtgD2QrPe6014LPEdv2DY+YSUQZ4cE=

-- db文件名
dbfilename dump63700.rdb

-- log 日志文件路径
logfile "/usr/local/redis/etc/redis_63700.log"

-- 安全考虑,rename-command 配置以下命令
rename-command FLUSHALL "payngithubFLUSHALL"

rename-command CONFIG "payngithubCONFIG"

rename-command SHUTDOWN "payngithubSHUTDOWN"

rename-command DEBUG "payngithubDEBUG"

启动redis服务,并指定启动服务配置文件,检测运行端口,为了安全,请不要使用root用户去启动

$ sudo chown -R www:www  /usr/local/redis/    //赋予指定该用户组,而非root账号
$ /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis6379.conf
$ ps -aux | grep redis
www      70764  0.6  0.1  38160      0:00 /usr/local/redis/bin/redis-server 127.0.0.1:63700
www   70768  0.0  0.0  15984      0:00 grep --color=auto redis

redis-cli启动、检测重置命令是否生效(结果:配置文件已经OK)

$ redis-cli -h 127.0.0.1 -p 63700 -a b6Pbc42gP8hXPNLzZaDnhREijtn1BSVSIYTkhTXw8SuPGpWZvN5kVpVeEVBdEQDw7M/+EZuDS6FxTOtgD2QrPe6014LPEdv2DY+YSUQZ4cE= 
  127.0.0.1:63700> set username tinywan
  OK
  127.0.0.1:63700> get username
  "tinywan"
  127.0.0.1:63700> SHUTDOWN
  (error) ERR unknown command 'SHUTDOWN'
  127.0.0.1:63700> FLUSHALL
  (error) ERR unknown command 'FLUSHALL'
  127.0.0.1:63700> tinywangithubFLUSHALL
  OK
  127.0.0.1:63700> get username
  (nil)
  127.0.0.1:63700>

远程链接出现的错误:
错误信息

 xxxxxxxxxx DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password is requested to    clients.......  

修改配置文件:protected-mode yes 修改为protected-mode no

查看远程Redis服务器的版本 redis-cli -h 192.168.25.128 info | grep 'redis_version'

四、Redis开机启动的方法

Linux中设置Redis开机启动的方法

环境:Ubuntu 16.04.2 LTS
编辑脚本:vim /etc/init.d/redis

#!/bin/sh
#
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.
### BEGIN INIT INFO
# Provides:   redis6379
# Required-Start: $local_fs $network
# Required-Stop:  $local_fs
# Default-Start:  2 3 4 5
# Default-Stop:  0 1 6
# Short-Description: redis6379
# Description:  penavico redis 6379
### END INIT INFO

REDISPORT=6379  # 【1】修改一
EXEC=/usr/local/bin/redis-server
CLIEXEC=/usr/local/bin/redis-cli

PIDFILE=/var/run/redis_${REDISPORT}.pid
CONF="/usr/local/redis/etc/redis_6379.conf"  # 【2】修改二

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 
  • 注册事件,开机启动:update-rc.d redis defaults
  • 启动服务:sudo systemctl start redis
  • 停止服务:sudo systemctl stop redis
  • 查看服务是否启动:
ps -aux | grep redis
root      1722  0.0  0.8  44752  8300 ?        Ssl  13:08   0:00 /usr/local/bin/redis-server 127.0.0.1:6379
www       1730  0.0  0.1  14224  1024 pts/0    S+   13:08   0:00 grep --color=auto redis

五、Redis关闭

命令方式关闭

redis-cli -h 127.0.0.1 -p 6379
127.0.0.1:6379> shutdown

进程号杀掉redis

ps -ef | grep redis
kill -9 XXX

六、Redis数据迁移

  • 查找RDB文件:
sudo find / -name dump.rdb
  • 进行远程拷贝备份文件:
scp ./dump.rdb www@192.168.1.18:/home/www/redis/
  • 数据迁移步骤如下
    • (1)关闭目标Redis服务;
    • (2)将相应的RDB文件或者AOF文件复制过去;
    • (3)设置REDIS的DIR或者开启AOF功能;
    • (4)启动目标REDIS服务;
