sentinel redis 集群部署+zabbix监控配置+性能测试+多实例自动配置脚本

一、集群架构:

二、服务器配置：

cpu：4核

内存：16G

硬盘：50G

三、安装命令：

cd /opt/redis/

ls

yum install tcl -y

tar xf redis-3.2.9.tar.gz

yum install gcc -y

ls

cd redis-3.2.9

ls

make

make test

ls

mkdir /etc/redis #存放redis配置文件

ln -s /opt/redis/redis-3.2.9/src/redis-cli /usr/sbin/redis-cli

ln -s /opt/redis/redis-3.2.9/src/redis-server /usr/sbin/redis-server

ln -s /opt/redis/redis-3.2.9/src/redis-sentinel /usr/sbin/redis-sentinel

四、配置文件信息：

1、redis 从节点配置文件信息，将该文件保存到/etc/redis目录下

bind 0.0.0.0

protected-mode no

port 4379

tcp-backlog 511

timeout 300

tcp-keepalive 300

#requirepass redis

supervised no

pidfile "/var/run/redis_4379.pid"

loglevel notice

logfile ""

databases 16

#save 900 1

#save 300 10

#save 60 10000

stop-writes-on-bgsave-error yes

aof-rewrite-incremental-fsync yes

# Generated by CONFIG REWRITE

maxmemory 200mb

maxmemory-policy noeviction

slaveof xx.xx.xx.xx 4379 #主节点将这一行注释掉

2、sentinel 配置文件

port 14379

daemonize yes

protected-mode no

dir "/opt/redis-3.2.1"

logfile "/var/log/sentinel.log"

sentinel monitor r1 xx.xx.xx.xx 4379 2

sentinel down-after-milliseconds r1 20000

sentinel parallel-syncs r1 1

sentinel failover-timeout r1 30000

# Generated by CONFIG REWRITE

3、redis 启动、关闭脚本，将该文件放到/etc/init.d/目录下，并给与执行权限

#!/bin/sh

#

# Simple Redis init.d script conceived to work on Linux systems

# as it does use of the /proc filesystem.

REDISPORT=4379

EXEC=/usr/sbin/redis-server

CLIEXEC=/usr/sbin/redis-cli

PIDFILE=/var/run/redis_${REDISPORT}.pid

CONF="/etc/redis/redis.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

五、启动redis和sentinel：

/etc/init.d/redis start

/usr/sbin/redis-sentinel /etc/redis/sentinel.conf

六、redis多实例自动配置脚本

#!/bin/bash

set -e

#获取端口号

[ $# -ne 1 ] && echo "Please enter the port number (For example: ./redis-add.sh 4379)" && exit 1

#RP=`echo $1`

RP=$1

#查看配置文件是否存在

if [ -f /etc/redis/redis_$RP.conf ];then

echo "Warning:There are already exists /etc/redis/redis_$RP.conf,Please check" && exit 1

elif [ -f /etc/redis/sentinel_$RP.conf ];then

echo "Warning:There are already exists /etc/redis/sentinel_$RP.conf,Please check" && exit 1

elif [ -f /etc/init.d/redis_$RP ];then

echo "Warning:There are already exists /etc/init.d/redis_$RP,Please check" && exit 1

fi

#生成配置文件

/bin/cp /etc/redis/bak/redis.conf.bak /etc/redis/redis_$RP.conf

/bin/cp /etc/redis/bak/sentinel.conf.bak /etc/redis/sentinel_$RP.conf

/bin/cp /etc/init.d/redis /etc/init.d/redis_$RP

#修改配置文件

SRP=$(( $RP + 10000 ))

#echo $SRP

sed -i s/4379/$RP/ /etc/redis/redis_$RP.conf

sed -i s/4379/$RP/ /etc/redis/sentinel_$RP.conf

sed -i s/r1/r$RP/ /etc/redis/sentinel_$RP.conf

sed -i s/sentinel.log/sentinel_$SRP.log/ /etc/redis/sentinel_$RP.conf

sed -i s/14379/$SRP/ /etc/redis/sentinel_$RP.conf

sed -i s/4379/$RP/ /etc/init.d/redis_$RP

sed -i s/redis.conf/redis_$RP.conf/ /etc/init.d/redis_$RP

#启动redis和sentinel

echo "/etc/init.d/redis_$RP start" >> /etc/rc.d/rc.local

echo "/usr/sbin/redis-sentinel /etc/redis/sentinel_$RP.conf" >> /etc/rc.d/rc.local

/etc/init.d/redis_$RP start

wait

/usr/sbin/redis-sentinel /etc/redis/sentinel_$RP.conf

七、zabbix监控脚本：

#!/bin/bash

HOST="127.0.0.1"

PORT=$1

# 检测redis性能

function Clients {

/usr/sbin/redis-cli -h $HOST -p $PORT info Clients | awk -F':' 'NR==2{print $2}'

}

function Memory {

used_memory=`/usr/sbin/redis-cli -h $HOST -p $PORT info Memory | awk -F':' 'NR==2{print $2}'| grep -o "[0-9]\+"`

max_memory=`/usr/sbin/redis-cli -h $HOST -p $PORT info Memory | awk -F':' 'NR==12{print $2}'| grep -o "[0-9]\+"`

usage_memory=`expr $used_memory \* 100 / $max_memory`

echo $usage_memory

}

function Slowlog {

/usr/sbin/redis-cli -h $HOST -p $PORT slowlog len | awk '{print $1}'

}

function Info {

/usr/sbin/redis-cli -h $HOST -p $PORT info Server &>/tmp/info.txt

INFO=`cat /tmp/info.txt | awk 'NR==1{print $2}' | grep -o -i "[a-z]\+"`

if [ "$INFO" == "Server" ];then

INFO1=1

else

INFO1=0

fi

echo $INFO1

}

# 执行function

$2

八、性能测试：

cd /opt/redis/redis-3.2.9/src/

./redis-benchmark -h xx.xx.xx.xx -p 6379 -c 30 -n 100000 -q > /opt/redis/log/30.log
