Redis 集群搭建 哨兵模式搭建

Redis version 6.0.5 集群搭建

下载文件

下载 命令 url 可找官网  复制
wget http://download.redis.io/releases/redis-6.0.5.tar.gz

环境安装

yum install gcc-c++
yum install cpp 
yum install binutils
yum install glibc 
yum install glibc-kernheaders
yum install glibc-common
yum install glibc-devel
yum install gcc
yum install make
yum -y install centos-release-scl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils

解压

创建redis文件夹
cd /home
mkdir redis
cd redis
解压 
tar -zxvf redis-6.0.5.tar.gz
重命名
mv redis-6.0.5 redis-1
复制 
cp -r redis-1 redis-2
cp -r redis-1 redis-3 

编译

cd /home/redis/redis-1
每一个redis执行下行命令
scl enable devtoolset-9 bash
如果以以下编译安装 的命令失败 基本上是因为 环境安装问题 可以直接百度 相关更全面的安装环境
make MALLOC=lib
make install

密码设置

# 两台机器一台master，一台slave，两个sentinel
#master修改
#1. redis.conf
requirepass 123456        #添加密码
#2. sentinel.conf
sentinel auth-pass mymaster 123456     #连接master密码
#slave修改
#1. redis.conf
masterauth 123456    #连接master密码
slaveof 10.100.134.109 6379  #slaveof表示该机器是slave，后边ip为master地址和端口
#2. sentinel.conf
sentinel auth-pass mymaster 123456     #连接master密码,这个配置一定要在sentinel monitor 配置之后
