前言
本文将介绍如何安装和配置Redis单机版和扩展集群版。首先,我们会详细说明如何安装Redis单机版,并提供了相应的脚本来简化安装过程。然后,我们会介绍如何在已经安装好的Redis单机版基础上搭建扩展集群,并提供了相应的脚本来帮助您完成这一步骤。最后,我们还会演示一些测试命令以验证集群是否正常工作。
一、Redis单机版安装教程
1. 复制脚本
首先,将以下脚本内容复制并保存为/tmp/install_redis.sh文件。
#!/bin/bash# 安装版本
redis_version="6.2.7"
# 安装目录
#redis_installDir="/opt/module/redis"
redis_installDir="/opt/bigdata/redis"install_redis() {local version=$1local installDir=$2local redisconf_file=$installDir/redis-$version/redis.conf# 安装工具包yum -y install epel-release gcc make tcl# 下载地址local downloadUrl="http://download.redis.io/releases/redis-$version.tar.gz"if [ -z "$(command -v wget)" ]; thenyum -y install wgetif [ $? -eq 0 ]; thenecho "wget安装完成"elseecho "wget安装失败,请检查"exit 1fifiif [ ! -d "${installDir}" ]; thenmkdir -p "${installDir}"if [ $? -eq 0 ]; thenecho "安装目录${installDir}已创建"elseecho "请确保您有足够的权限来创建目录,请增加权限后再次执行"exit 1fifiif [ ! -f "/tmp/redis-$version.tar.gz" ] ; thenwget "$downloadUrl" -P /tmpif [ $? -eq 0 ]; thenecho "redis-$version.tar.gz下载成功"elseecho "redis-$version.tar.gz下载失败,请重试或手动下载到/tmp目录下再次执行"echo "下载地址:$downloadUrl"exit 1fielseecho "/tmp/redis-$version.tar.gz文件已存在"fiif [ -d "${installDir}/redis-$version" ]; thenecho "${installDir}/redis-$version 已存在,正在删除..."rm -rf "${installDir}/redis-$version"fitar -zxvf "/tmp/redis-$version.tar.gz" -C "${installDir}"if [ $? -eq 0 ]; thenecho "redis-$version.tar.gz解压成功"elseecho "redis-$version.tar.gz解压失败,请查看异常信息后重试"exit 1fi# 编译和安装cd ${installDir}/redis-$versionmake && make installsed -i "s|daemonize no|daemonize yes|" "$redisconf_file"sed -i "s|bind 127.0.0.1 -::1|bind 127.0.0.1 -::1\nbind 0.0.0.0|" "$redisconf_file"sed -i "s|# requirepass foobared|# requirepass foobared|" "$redisconf_file"# sed -i "s|port 6379|port 6379|" "$redisconf_file"

2. 增加执行权限
在终端中执行以下命令,为脚本添加执行权限。
chmod a+x /tmp/install_redis.sh
3. 执行脚本
执行以下命令,运行脚本开始下载、安装和配置Redis。
/tmp/install_redis.sh
请等待安装完成,如有异常会有提示。
成功如下图所示:
二、Redis扩展集群版安装教程
1. 安装Redis单机版
要安装Redis扩展集群版,要先安装好单机版。
2. 复制脚本
首先,将以下脚本内容复制并保存为/opt/bigdata/redis/redis-6.2.7/redis_cluster.sh文件。
#!/bin/bash# 安装版本

echo "clean -- Remove all instances data, logs, configs."
echo "clean-logs -- Remove just instances logs."
echo "call <cmd> -- Call a command (up to 7 arguments) on all nodes."
3. 增加执行权限
在终端中执行以下命令,为脚本添加执行权限。
cd /opt/bigdata/redis/redis-6.2.7
chmod a+x ./redis_cluster.sh
4. 执行脚本
执行以下命令,运行脚本开始创建Redis扩展集群的目录。
./redis_cluster.sh start
如下图所示:
执行以下命令创建Redis扩展集群。
echo yes | ./redis_cluster.sh create
成功的开始和结束的截图如下图所示:
5. 测试
执行以下命令进入Redis扩展集群交互界面。
redis-cli -h 192.168.145.105 -c -p 30001
使用命令测试是否正常,如下图所示。
6. redis_cluster.sh 命令
6.1 启动Redis扩展集群
cd /opt/bigdata/redis/redis-6.2.7
./redis_cluster.sh start
6.2 停止Redis扩展集群
cd /opt/bigdata/redis/redis-6.2.7
./redis_cluster.sh stop
6.3 查看Redis扩展集群节点信息
cd /opt/bigdata/redis/redis-6.2.7
./redis_cluster.sh watch
6.4 查看Redis扩展集群实时日志
cd /opt/bigdata/redis/redis-6.2.7
./redis_cluster.sh tail 1
6.5 清除Redis扩展集群目录所有数据
cd /opt/bigdata/redis/redis-6.2.7
./redis_cluster.sh clean
6.6 清除Redis扩展集群目录日志数据
cd /opt/bigdata/redis/redis-6.2.7
./redis_cluster.sh clean-logs
总结
通过本教程,您学习到了如何在Linux系统上进行Redis的安装和配置。首先,您学习到了如何使用脚本自动下载、编译和安装Redis单机版,并对其进行必要的配置修改以满足实际需求。然后,在已经部署好的单机版基础上,您学习到了如何使用另一个脚本创建并启动一个具有多个节点(主节点+从节点)组成的扩展集群。
