3. Redis starts and closes the script, places the file in the / etc/init.d/ directory, and gives execution permission
#! / bin/sh

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

5. Start redis and sentinel:
/ etc/init.d/redis start
/ usr/sbin/redis-sentinel / etc/redis/sentinel.conf
6. Redis multi-instance automatic configuration script
#! / bin/bash
Set-e
# get the port number
[$#-ne 1] & & echo "Please enter the port number (For example:. / redis-add.sh 4379)" & & exit 1
# RP= `echo $1`
RP=$1
# check whether the configuration file exists
If [- f / etc/redis/redis_$RP.conf]; then

7. Zabbix monitoring script:
#! / bin/bash
HOST= "127.0.0.1"
PORT=$1
# testing redis performance
Function Clients {
/ usr/sbin/redis-cli-h $HOST-p $PORT info Clients | awk-favored rig''NR==2 {print $2}'
}

Used_memory= `/ usr/sbin/redis-cli-h $HOST-p $PORT info Memory | awk-fanglu 'NR==2 {print $2}' | grep-o "[0-9]\ +"`
Max_memory= `/ usr/sbin/redis-cli-h $HOST-p $PORT info Memory | awk-fanglu 'NR==12 {print $2}' | grep-o "[0-9]\ +"`
Usage_memory= `expr $used_memory\ * 100 / $max_ expy`
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 $2}' | grep-o-I "[Amurz]\ +" `
If ["$INFO" = = "Server"]; then
INFO1=1
Else
INFO1=0
Fi
Echo $INFO1
}
# execute function

8. Performance testing:
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
