如何开机自启动

启动脚本 redis_init_script 位于位于redis的 /utils/目录下

复制此脚本文件至/etc/init.d目录下

cp /usr/local/redis-3.0.5/utils/redis_init_script /etc/init.d/redis

修改文件

vi /etc/init.d/redis

#!/bin/sh
# chkconfig:   2345 80 90
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.

REDISPORT=6379
EXEC=/usr/local/redis-3.0.5/src/redis-server 
CLIEXEC=/usr/local/redis-3.0.5/src/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

和原配置文件相比： 

1.原文件是没有以下第2行的内容的，

#chkconfig: 2345 80 90 

我自己改写的文件

#!/bin/bash  
# Startup script for the redis
# chkconfig: 2345 80 90
# description: The redis daemon is a network memory cache service.
# processname: redis  
# pidfile: /var/run/redis.pid 
REDISPORT=6379  
EXEC=/usr/local/redis-3.0.5/src/redis-server   
CLIEXEC=/usr/local/redis-3.0.5/src/redis-cli   
PIDFILE=/var/run/redis_${REDISPORT}.pid  
CONF="/etc/redis/${REDISPORT}.conf" 
RETVAL=0  
prog="redis"  
# Source function library.  
. /etc/init.d/functions  
# Source networking configuration.  
. /etc/sysconfig/network  
# Check that networking is up.  
[ ${NETWORKING} = "no" ] && exit 0  
[ -x $EXEC ] || exit 0  
# Start redis daemons functions.  
start() {  
   if [ -f $PIDFILE ];then  
      echo "$PIDFILE exists, process is already running or crashed"  
      exit 1  
   fi  
   echo  $"Starting $prog: "  
   $EXEC $CONF & 
   RETVAL=$?  
   return $RETVAL  
}  
# Stop redis daemons functions.  
stop() {  
   if [ ! -f $PIDFILE ];then  
      echo "$PIDFILE exists, process is already running or crashed"  
      exit 1  
   fi 
   echo -n $"Stopping $prog: "  
   PID=$(cat $PIDFILE)
   $CLIEXEC -p $REDISPORT shutdown 
   while [ -x /proc/${PID} ]
   do
      echo "Waiting for Redis to shutdown ..."  
      sleep 1  
   done 
   echo "redis stopped"  
   RETVAL=$?  
}  
# See how we were called.  
case "$1" in  
start)  
        start  
        ;;  
stop)  
        stop  
        ;;  
restart|reload)  
        stop  
        start  
        ;;  
*)  
        echo $"Usage: $prog {start|stop|restart|reload}"  
        exit 1  
esac  
exit $RETVAL  

你喜欢的话，也可以用我改写的噢

2.原文件EXEC、CLIEXEC参数，也是有所更改。

1 2	EXEC=/usr/local/redis/bin/redis-server CLIEXEC=/usr/local/redis/bin/redis-cli

3.redis开启的命令，以后台运行的方式执行，加上 &

$EXEC $CONF & 

ps:注意后面的那个“&”，即是将服务转到后面运行的意思，否则启动服务时，redis服务将 占据在前台，占用了主用户界面，造成其它的命令执行不了。

将redis配置文件拷贝到/etc/redis/${REDISPORT}.conf  

mkdir /etc/redis

cp /usr/local/redis-3.0.5/redis.conf /etc/redis/6379.conf

修改此配置文件

daemonize no                    //修改为yes    使redis以守护进程模式启动

pidfile /var/run/redis.pid        //修改为/var/run/redis_6379.pid    设置redis的PID文件的路径

赋予redis文件执行权限

chmod +x /etc/init.d/redis

添加服务

chkconfig --add redis

设置开机启动

chkconfig --level 35 redis on

查看是否设置成功

chkconfig --list | grep redis

此状态下表面开机启动成功

service方式启动redis服务

service redis start

service方式停止redis服务

service redis stop

将redis的命令所在目录添加到系统参数PATH中

修改profile文件：

vi /etc/profile

追加

export PATH=$PATH:$JAVA_HOME/bin:/usr/local/redis-3.0.5/src

使配置文件立即生效

source /etc/profile

这样就可以直接调用redis-cli的命令了，如下所示： 

退出客户端输入quit即可

检测后台进程是否存在

ps -ef|grep redis

检测6379端口是否在监听

netstat -tunpl | grep 6379

密码认证

打开 /etc/redis.conf 修改 requirepass 配置项

# vim /etc/redis.conf

requirepass test123

# service redis restart
Stopping redis-server:                                     [  OK  ]
Starting redis-server:                                     [  OK  ]

# redis-cli
redis 127.0.0.1:6379> set h helloworld
(error) ERR operation not permitted

auth test123

redis 127.0.0.1:6379> auth test123
OK
redis 127.0.0.1:6379> set h helloworld
OK
redis 127.0.0.1:6379> get h
"helloworld"
redis 127.0.0.1:6379> exit

redis-cli -a 参数指定密码

# redis-cli -a test123
redis 127.0.0.1:6379> set h helloworld
OK
redis 127.0.0.1:6379> get h
"helloworld"
redis 127.0.0.1:6379> exit

通过 config 动态改变密码，无需重新启动 redis 进程

# redis-cli -a test123
redis 127.0.0.1:6379> config get requirepass
1) "requirepass"
2) "test123"
redis 127.0.0.1:6379> config set requirepass passabc
OK
redis 127.0.0.1:6379> auth passabc
OK
redis 127.0.0.1:6379> set h helloworld
OK
redis 127.0.0.1:6379> get h
"helloworld"
redis 127.0.0.1:6379> exit

master/slave 模式， master 有密码, slave 怎样配置？

masterauth  password

redis的主从配置

1、选中一台服务器作为master

2、其它服务器作为slave

       修改/etc/redis/6379.conf配置文件

       找到# slaveof <masterip> <masterport>

把此配置注释放开，写上master的ip 端口号即可

如

slaveof 192.168.1.101 6379

重启服务，即可发现master机子中的相关数据已经同步到所有的slave从机中
