這兩天工作有空閒，所以看了一下redis文件，決定按照文件搭建一套測試環境，做一下叢集的測試。在開始配置叢集時，官方推薦採用6個節點，但是測試樣例中需要手動建立每個節點的目錄和配置檔案。正好最近想學習一下指令碼，所以寫了一個指令碼進行自動建立節點，用來學習shell指令碼編寫。本文只是學習記錄，如有打擾請見諒。

指令碼程式碼如下

#!/bin/bash
if [ $# -ne 3 ]
then
        echo "scan param count is : $#"
        echo "scan param is : $*"
        exit 1
fi

REDIS_BASE_PATH=$1
REDIS_START_PORT=$2
REDIS_INSTENCE_NUM=$3

echo "redis base path is ${REDIS_BASE_PATH}"
echo "redis start port is ${REDIS_START_PORT}"
echo "redis instence num is ${REDIS_INSTENCE_NUM}"

if [ $REDIS_INSTENCE_NUM -gt 0 ]
then
        echo "redis instence is $REDIS_INSTENCE_NUM"
        int=1
        while (($int<=${REDIS_INSTENCE_NUM}));
        do
                redis_config_path=$REDIS_BASE_PATH/$REDIS_START_PORT
                redis_config_file=$redis_config_path/redis.conf
                mkdir -p $redis_config_path
                echo "mkdir path is $redis_config_path"
                touch $redis_config_file
                echo "touch file is $redis_config_file"
                chmod 777 $redis_config_file
                echo "port $REDIS_START_PORT" > $redis_config_file
                echo "cluster-enabled yes" >> $redis_config_file
                echo "cluster-config-file nodes.conf" >> $redis_config_file
                echo "cluster-node-timeout 5000" >> $redis_config_file
                echo "appendonly yes" >> $redis_config_file
                let "int++"
                let "REDIS_START_PORT++"
        done
else
        echo "redis instence is 0"
        exit 1
fi
exit 0
