二、安装
文档参考：https://blog.csdn.net/miss1181248983/article/details/90056960
1、部署规划
| c1 | port | c2 | port | c3 | port |
|---|---|---|---|---|---|
| 192.168.139.12 | 6379 | 192.168.139.15 | 6379 | 192.168.139.16 | 6379 |
| 192.168.139.15 | 6380 | 192.168.139.16 | 6380 | 192.168.139.12 | 6380 |
2、redis-5.0.7的安装
2.1、安装
# 安装所需依赖
# yum install gcc-c++ automake autoconf libtool make -y
# yum install -y gcc*
# 下载所需安装包
# wget http://download.redis.io/releases/redis-5.0.7.tar.gz
# 解压编译安装
# tar xzf redis-5.0.7.tar.gz
# cd redis-5.0.7
# make -j 4 && make install PREFIX=/app_server/redis
# 新建相关目录
# cd /app_server/redis
